IT Conference White Paper - Essay Example However, the PSI-CoE has also indicated its interest in increasing effectiveness, efficiency, cost saving and productivity of the program. Army requests are currently the only requests being processed by the CoE; this however rules out the army reserves and the national guards. The main objective behind this move was to ensure the CoE had the sole responsibility of issuing security clearances and at the same time, bring down any other channel apart from the CoE that issued security clearances. Initially, about 36% of the total requests are being accepted with percentage destined to rise significantly after merging. Pros and Cons Pros The APG will acquire a new platform, while at the same time the additional technical personnel will boost its operations by making it efficient and effective. The APG NEC is currently indicated to lack high bandwidth pipes connecting its different locations, thus the building up of an updated network infrastructure will upgrade the process of attaining a nd working on the information received in the APG NEC. In addition to this, supplementing technical support will also increase efficiency and effectiveness of the Aberdeen Providing Ground Network Enterprise Center. The joint services between the various departments of security will enhance corporation between the numerous personnel involved in the different departments. A good example as indicated is the facilitation of the military intelligence (COEMI) by the Intelligence command (INSCOM). In addition to this, workstation maintenance is destined to be provided by the APG NEC especially if the joint services between the CoE and the MI are undertaken. Moreover, improvement of security is guaranteed upon undertaking the course of action. This will be made possible as the crucial facilities such as the technical and network infrastructure will undergo upgrading or complete makeover. Self-reliance and self-containment will also be upheld in missions, as it will provide the APG NEC with greater flexibility. In order to achieve self-reliance, the mission will rely on organic staffing (Personnel Security Investigation ââ¬â Center of Excellence (PSI-CoE) IT Way Ahead Conference

Business Plan Assignment Example | Topics and Well Written Essays - 1250 words
Business Plan - Assignment Example The existing capacity of Protrich is not able to meet the demand for the products in its various markets. If the company is not able to expand the capacity for the existing demand and for the anticipated future demands, it will lose the market to other major competitors. Also, the Protrich need to expand as an international brand rather than confining itself to the south Indian and Middle East market. The potential markets for Protrich are China, Europe and USA. In order to compete in China, Europe and USA markets, Protrich will not only have to focus on the quality aspect but also on the cost aspect. For having an edge over the price, Protrich should adopt cost effective manufacturing. This is possible in India only up to a certain limit. Therefore, to have an even lower cost of production, it is better for Protrich to setup manufacturing unit in China. China, along with Netherlands accounts for more than 50% of the exports of white button mushrooms. Chinaââ¬â¢s mushroom producti on has been in question for several times including certain countries imposing even anti-dumping measures on them. But this is mainly based on the fact that there wasnââ¬â¢t much notable technology being used for production process in the country. (Mushroombusiness, 2011) But Protrich being a company with all technological support for production, quality of production will never be in question. This report will analyze the benefits for Protrich to invest in China. Analysis Home Country The home country of the company is India. India as a mushroom market is not well flourished. There are very few established brands in the country. Even for the established brands, the market coverage will be limited. Retail customers are mainly from the upper middle class and above. Even for them, mushroom is not a frequent item on the dining table. But there is huge demand from hotels and restaurant chains. This is the customer group from which Mushroom companies have a steady demand. Dominos Pizz a and US Pizza has been the customers of Protrich for six years and four years respectively. Apart from these established brands, there are also many other mediocre restaurant chains who are frequent customers of Protrich. Protrichââ¬â¢s major market is the southern states of India such as Kerala (the companyââ¬â¢s home state), Karnataka, Tamil Nadu and Andhra Pradesh. Protrichââ¬â¢s products are available only in the major cities of these states. It is not distributed widely to include the smaller towns because there is very less demand in the smaller towns and cities. Even in the cities, the products will be available only in supermarkets. Protrich enjoys third position in terms of market share. The market leaders are Best Mushroom Limited and Mushroom India Limited. Protrich is almost at par with the market leaders in terms of the brand value. In the UAE market all the three brands are very popular. The advantage of current expansion move of Protrich is that it will be a ble to gain market share over the other two. Neither Best Mushroom nor Mushroom India has a market presence in Europe and USA. At this point, if Protrich is able to provide the market with quality products, it will be advantageous for the company in terms of brand value and market share. Host Country The potential host markets of Protrich are China, Europe and USA. Among these, foreign direct investment will be made by Protrich in China where it intends to setup the manufacturing units. The analysis will be based on the

Assessing General George Thomas Essay Example | Topics and Well Written Essays - 1250 words
Assessing General George Thomas - Essay Example In his early days, George would show his feelings towards the disenfranchised, despite the consequences present at the time. In this case, "George Henry Thomas was born July 31, 1816, at Newsom's Depot, VA. Growing up on a plantation, Thomas was one of many who violated the law and taught his family's slaves to read," ("About.com", p.1). From a personal standpoint, Thomas' desire to help those despite the presence of existing laws against such help at the time, would show a sense of character and consideration for those around him. At a point in time, George would seek to pursue a career in law. Such a career path choice, would last for only a short period of time. It would be at this period in time that George would elect to enroll at West Point. While at the academy, one of his associates would be William T. Sherman, who shared a room with the young Thomas. At this point in time, "Becoming friendly rivals, Thomas soon developed a reputation among the cadets for being deliberate and cool-headed. Graduating 12th in his class, Thomas was commissioned as a second lieutenant and assigned to the artillery," ("About.com", p.1). By having a mentality of sharp thinking and level headedness, it would enable Thomas to effectively execute his responsibilities to the men and his unit and better serve the cause. The com The commanding officer which George would have had during the Second Seminole conflict that took place in Florida, described him in this manner, "I never knew him to be late or in a hurry. All his movements were deliberate, his self-possession was supreme...," ("About.com", p.1). By taking into consideration the appraisal of George Thomas by his commanding officer, it would further outline a man who would possess an attitude towards structure and a conviction for steadfast behavior. General Thomas' career would essentially begin with the Mexican American War. During this conflict, Thomas would be provided with the opportunity to increase his held rank not once, but in fact would do it twice. With regards to the Civil War, George Thomas would see his career begin in one area and then shift to another as time would go on. He would take part in the conflict known as the First Battle of Manassas but in the end, would be transferred to what would be referred to as the western theatre for the remainder of the war. In reference to the time after Thomas would arrive in the western region of the battle front, "Thomas began his time in the Western Theater by commanding an independent force in eastern Kentucky, which defeated Confederate forces at Mill Springs in early 1862," ("George Thomas", p.1). As one of the battles that Thomas would be a part of, this battle would provide to be essential. In these terms, "This battle is seen as one of the first important Union victories in the war," ("George Thomas", p.1). For this battle to have been considered an important aspect of the victories seen by the union movement that would only serve to elevate George Thomas, to an even higher standing within the military hierarchy of status and importance. It would be during the same year as the victory seen at Mill Springs that George Thomas would see another increase in rank. This time, he would in fact become a Major General and would take, "..command of four divisions from Grant's former Army of the Tennessee and one from the

Bedside Index for Severity in Acute Pancreatitis (BISAP)
Bedside Index for Severity in Acute Pancreatitis (BISAP) Abstract Objectives The aim of this study was to evaluate the diagnostic performance of Bedside Index for Severity in Acute Pancreatitis (BISAP) score for predicting severe acute pancreatitis (SAP) in the early phase. Method The PubMed, Cochrane library and EMBASE databases were searched until May 2014. The strict selection criteria and exclusion criteria were determined, and we applied hierarchic summary receiver operating characteristic (HSROC) model and bivariate random effects models to assess thediagnosibility of the BISAP score for predicting SAP. We obtained pooled summary statistics for sensitivity, specificity, positive likelihood ratio (PLR), negative likelihood ratio (NLR), diagnostic odds ratio (DOR) and calculated the area under the HSROC curve (AUC). The 95% confidence intervals (CI) for each diagnostic test measure were also calculated. Publication bias was assessed using Deekââ¬â¢s funnel plot asymmetry test. Statistical analyses were performed using the STATA12.0 software. Results The pooled sensitivity, specificity, PLR, NLR, and DOR were 64.82%, 83.62%, 3.96, 0.42 and 9.41, respectively. The AUC was 0.77 and the HSROC curve for individual studies was generated and analyzed to explore the influence of threshold effects. Conclusion We confirmed that BISAP score is an accurate means to predict SAP in the early phase. Keywords: BISAP, HSROC curve, severe acute pancreatitis, acute pancreatitis Introduction Acute pancreatitis (AP) is an inflammatory condition of the pancreas with a clinical course that varies from mild to severe and characterized by activation of pancreatic enzymes to cause self-digestion of the pancreas 1. Generally, AP is mild, self-limiting, and requires no special treatment and ranges about 80-90% of patients with only minimal or transitional systemic manifestations, but about 20%-30% of patients develop a severe disease that can progress to systemic inflammation and cause pancreatic necrosis, multi-organ failure, and potentially death 1-4. So it is important to have an early, quick, and accurate risk stratification of AP patients, which would permit evidence-based early initiation of intensive care therapy for patients with severe AP (SAP) to prevent adverse outcomes and allow treatment of mild AP (MAP) on the common ward. Early identification of patients with SAP would allow the clinician to consider more aggressive interventions within a time frame that could pre vent possible complications. Currently, there are a variety of score systems developed for the early detection of SAP, such as Ransonââ¬â¢s score 5, acute physiology and chronic health examination (APACHE) II 6, 7 and computed tomography severity index (CTSI) 8. Also there are many inflammation markers such as C-reactive protein (CRP), interleukin-6 (IL-6) and others 9, 10. Several studies show that cytokines play an important role in the cascading inflammatory responses 11 and it may act as mediators of distant organ complications in SAP. So the levels of cytokine in serum may also reflect the degree of the inflammatory response 12. In 2008, Wu et al. 13 proposed a new prognostic scoring system, the bedside index of severity in acute pancreatitis (BISAP), is a simple and accurateà ¢Ã¢â ¬Ã¢â¬Å¾ method that can predict the clinical severity of AP within 24 h of presentation. BISAP incorporates five parameters: blood urea nitrogen > 25 mg/dL, impaired mental status, systemic inflammatory response syndrome ( SIRS), age > 60 years, and detection of pleural effusion by imaging 14. Unfortunately there has been no systematic or meta-analytic review of cross-sectional studies of this scoring system. The purpose of this study was to aggregate the reported data across the different studies and to assess the ability of the BISAP score to predict SAP. Materials and methods 2.1 Literature search The search was performed on three databases: PubMed, Cochrane library and EMBASE. These databases were searched from the first date available in each database up to May 2014, using the search terms ââ¬Ëacute pancreatitisââ¬â¢ AND (ââ¬ËBISAPââ¬â¢ OR ââ¬Ëbedside index of severity in acute pancreatitisââ¬â¢). Once articles had been collected, bibliographies were then hand-searched for additional references. 2.2 Inclusion and Exclusion Criteria To be included in this meta-analysis, studies must meet the following criteria: (1) studies evaluate the BISAP score for predicting SAP; (2) the subjects were diagnosed with AP; (3) prospective study; (4) the absolute numbers of true positive (TP), false negative (FN), false positive (FP), and true negative (TN) test results were available or derivable from the article; (5) the clinical result of patients was indicated as SAP. Studies were excluded if one of the following existed: (1) the numbers of TP, FN, FP, and TN test results were not derivable from the article; (2) cross-sectional study; (3) non-original articles, such as review, meeting abstract, case report and comment; (4) duplicate of previous publications and data description is not clear. 2.3 Data extraction and quality assessment All data were extracted independently by two authors according to the inclusion criteria listed above. Disagreements were resolved by discussion or solved by consultation of a third reviewer. The following characteristics were collected from each study: the first author, year of publication, source, experiment design, sample size, the reference standard (gold standard), the numbers of TP, FN, FP, and TN and others. The QADAS (Quality Assessment of Diagnostic Accuracy Studies) criteria were used to assess the quality of diagnostic accuracy studies included in this meta-analysis 15. Statistical analyses Hierarchical summary receiver operating characteristic (HSROC) modeland bivariate random effects model were performed in STATA 12.0 (StataCorp, College Station, TX, USA) software using the program ââ¬Ëmetandiââ¬â¢ to generate pooled accuracy estimates of sensitivity, specificity, positive likelihood ratio (PLR), negative likelihood ratio (NLR), diagnostic odds ratio (DOR) and calculated the area under the HSROC curve (AUC) 16. The HSROC curve for individual studies was generated and analyzed to explore the influence of threshold effects. The 95% confidence intervals (CI) for each diagnostic test measure were also calculated. Publication bias was assessed using Deekââ¬â¢s funnel plot asymmetry test 17. Results 3.1 Eligible Studies The process of selecting studies for the meta-analysis was shown in Fig. 1. There were 32 studies potentially eligible studies identified. Of these, 14 studies were excluded after screening based on abstracts or titles to avoid obvious irrelevance. Finally, 9 studies 14, 18-25 met the inclusion criteria and were included in the meta-analysis. The data collected from the related studies was summarized in Table 1. Among these studies, kim et al. 20 reported the results of the meta-analysis with the cutoff values set at 2and 3, respectively. All patients were recruited within 24 h from the time of admission or transfer and used for the calculation of the BISAP scores. All included citations were prospective cohort studies. The absolute numbers of TP, FN, FP, and TN were calculated by sample size and the degree of sensitivity and specific. A summary of the quality of the studies was displayed in table 2. The included studies were not descript the tenth quality indicator (were the index test results interpreted without knowledge of the results of the reference?) and the eleventh quality indicator (were the reference standard results interpreted without knowledge of the results of the index test?) 15. At the same time, there are some studies not described in detail for eliminate and exit objects. 3.2 Meta-analysis The results of the HSROC model were show in Table 3. The pooled sensitivity of BISAP testing for the diagnosis of SAP was 64.82% (95% CI: 54.47%-73.74%), and the specificity was 83.62% (95%CI: 70.03%-91.77%). The pooled DOR was 9.41 (95%CI: 5.38-16.45), the PLR was 3.96 (95%CI: 2.27-6.89), and the NLR was 0.42 (95%CI: 0.34-0.52). The AUC of the HSROC was 0.77 (95%CI: 0.73-0.80) (Fig. 2). The I2 index of heterogeneity was 95% (95% CI, 91%-99%). 3.3 Subgroup Analyses There was a negative correlation between the logits of sensitivity and specificity (Spearman correlation coefficient, 20.09), indicating the present of an importanteffect of the diagnostic threshold (cutoff level) on the performance of BISAP score. The following cutoffs were selected for subgroups analysis (Table 4). Analysis of studies that set the BISAP cutoff point at 2, the pooled sensitivity, specificity, PLR, NLR, and DOR were 67.30% (95%CI: 60.53%-73.42%), 78.28% (95%CI: 68.86%-85.46%), 3.10 (95%CI: 2.12-4.52), 0.42 (95%CI: 0.34-0.51) and 7.42 (95%CI: 4.39-12.54), respectively. The AUC of the HSROC was 0.70(95%CI: 0.66-0.74). Analysis of studies that set the BISAP cutoff point at 3, the pooled sensitivity, specificity, PLR, NLR, and DOR were 61.18% (95%CI: 41.20%-78.00%), 88.64% (95%CI: 88%-97.18%), 5.39 (95%CI: 1.80-16.12), 0.44 (95%CI: 0.30-0.64), and (95%CI: 4.44-34.03), respectively. The AUC of the HSROC was 0.78 (95%CI: 0.75-0.82). 3.4 Publication Bias Deeksââ¬â¢ Funnel Plot Asymmetry Test for the overall analysis showed that no significant publication bias was found (P = 0.359, Fig. 3). Discussion Generally, Ranson, APACHE II, and CTSI scoring systems have been used to evaluate the severity of AP 22, 23. However, these techniques all have their inherent strengths and weaknesses. For example, the Ransonââ¬â¢s score 5 is relatively accurate at classifying the severity of AP, but the evaluation cannot be completed until 48 h, which will miss the potential for early treatment and increase mortality. The APACHE II system 6, 7 allows the determination of disease on the first day of admission and is more accurate than Ransonââ¬â¢s score, but complexity is its major drawback. CTSI 26, 27 is calculated based on CT findings of some local complications and cannot reflect the systemic inflammatory response. Recently, the BISAP score has been proposed as an accurate method for early identification of patients at risk for in hospital mortality 13. Several studies showed that BISAP score is a reliable and accurate means for predicting the severity of AP in the early phase 18, 22, 23. B ut these studies are not systematic, so we collect the reported data across the different studies and apply HSROC model and bivariate random effects model to assess the ability of the BISAP score to predict SAP. The pooled sensitivity, specificity, PLR, NLR, and DOR were 64.82%, 83.62%, 3.96, 0.42 and 9.41, respectively. The AUC of the HSROC was 0.77. Our meta-analysis indicated that BISAP score is a reliable and accurate means to predict SAP. This meta-analysis assessed the diagnostic performance of BISAP in 1972 individuals from 9 research studies 14, 18-25. The results show that the performance of BISAP to predict the severity of AP has a good specificity, but moderate sensitivity in predicting SAP. In addition, compared with other scoring systems in predicting SAP, BISAP has a higher specificity but a lower sensitivity 21-23, 28. The low sensitivity may be caused by these factors. First, the characteristics of study participants are differences (cultural and geographical differences), such as lifestyle, race, and genetic basis. Second, etiologic distribution may also explain the noted differences. Third, the different definitions of SAP may also be a reason for these variations. The HSROC curve presents a global summary of test performance and shows the tradeoff between sensitivity and specificity. The summary DOR and the AUC of the HSROC were 9.41 and 0.77, respectively.The predictive accuracy of BISAP scoring system was measured by AUC. An AUC of 1.0 represents a perfect test, whereas an AUC of 0.5 represents a test that performs no better than chance 29. The result revealed that the discrimination of disease severity was good in our study, which is similar to other reports. DOR is a single indicator of test accuracy that combines the sensitivity and specificity data into a single number. The DOR of a test is the ratio of the odds of positive test results in the patient with disease relative to the odds of positive test results in the patient without disease. The value of a DOR ranges from 0 to infinity, with higher values indicating better discriminatory test performance (higher accuracy).A DOR of 1.0 indicates that a test does not discriminate between pa tients with the disorder and those without it 30. In the present meta-analysis, we found that the pooled DOR was 9.41, also indicated a high level of overall accuracy. Since the HSROC curve and theDOR are not easy to interpret or use in clinical practice, and likelihood ratios are considered to be more clinically meaningful, we also presented both PLR and NLR as our measures of diagnostic accuracy. Likelihood ratios of > 10 or 31. The PLR and NLR value were 3.96 and 0.42, respectively. This result performed similar to traditional scoring systems in predicting SAP and suggested that the accuracy of still need to improve. But BISAP is relatively simple and had greater accuracy than other scoring systems, making it a promising method of predicting SAP 14, 19, 21, 28. Furthermore,it may be combined in medical decision-making at the extreme of the prediction range, such as enrollment criteria for clinical trials, and as triaging intensive care unit admission 32, 33. We also explored systematically the issue of heterogeneity by use of subgroup analysis. In our analysis, the diagnostic threshold presented an important effect on the performance of BISAP score. The results demonstrated that a BISAP score of 3 had greater accuracy and high predictive value than a score of 2 for predicting SAP. Our meta-analysis had several limitations. First, when the BISAP scoring system converts continuous variables into binary values of equal weight, it fails to capture synergistic or multiplicative effects based on the interactions of interdependent systems 21. Future research could focus on comprehensive reassessment of the pathologic mechanisms of AP with attention to the effects of preexisting risk factors (e.g. age, obesity, genetic) and well-defined end points, identification of accurate biomarkers to assess activity on these pathways, and mathematical models that have strong predictive accuracy. Second, the exclusion of conference abstracts, letters to the editor, and non-English-language studies might have led to publication bias, which was not found in the present review. However, a review of these abstracts and letters suggested that the overall results were similar to the results in the English language studies included. Third, there is a risk for publication bias in which positive results or results with ââ¬Ëexpectedââ¬â¢ findings are more likely to be published. We made every possible effort to minimize this type of bias by contacting investigators in the field of BISAP. If editors were more likely to publish manuscripts showing the ââ¬Ëexpectedââ¬â¢ results of a good diagnostic performance for BISAP, then our results may be overestimating the real diagnostic performance of BISAP. In conclusion, we confirmed that BISAP score is an accurate means to predict SAP in the early phase. Due to simplicity and easily obtained parameters, BISAP score should gain broad acceptance in routine use not by replacing clinical assessment, but rather by complementing and objectifying it.

Storming of the Bastille :: essays research papers
The characteristics of a group are determined by its elements. The mob that stormed the Bastille on July 14th, 1789 was a group of citizens that were fierce, enraged, and blood-thirsty. To the people of Paris, the Bastille was a symbol of brutality and totalitarian power. It was hated because of the many stories that had emerged from its walls of horrible torture and brutality. To the people of Paris who stormed the Bastille, the prison which was the symbol of the absolute monarchy which France had been suffering under for so long. They were tired of being treated unfairly and not having a voice in most of the political affairs during the time period. They wanted "life, liberty, fraternity" and were determined to fulfill their wishes of a fair ruling system by means of force or agreement. Unfortunately, citizens had to resort to the use of force to gain what the felt lacked. Later on that day, a delegation was invited into the prison by the Governor of the Bastille, Bernard de Launay. DeLaunay then invited the delegation to lunch with him. When they did not return the mob became angry, fearing that they had been detained. A second delegation was sent forth. These soon came out again with the message that the Governor had adamantly refused to surrender. The delegates also had the information that the cannon were unloaded. This piece of news was all that the mob needed to urge them on. "...But the fury of the crowd continued to increase and their blind wrath did not spare de Launay's escort...Exhausted by his efforts to defend his prisoner...he had to seperate from M. de Launay...Hardly had he sat down when, looking after the procession, he saw the head of M. de Launay stuck on the point of a pike...The people, fearing that their victim might be snatched away from them, hastened to cut his throat on the steps of the Hotel de Ville..." The mob rushed into the prisonââ¬â¢s courtyard. Some individuals were not as ruthless as others. "...Those who came in first treated the conquered enemy humanely and embraced the staff officers to show there was no ill-feeling..." However, several of the protestors were hurt as they attacked soldiers from the army. "....The people, transformed with rage, threw themselves on the sodiers..." Fierce fighting followed and carried on into the evening. Finally the mob got their hands on some cannons.

The 13 Forms of Insect Antennae
The 13 Forms of Insect Antennae Antennae are movable sensory organs located on the head of most arthropods. All insects have a pair of antennae, but spiders have none. Insect antennae are segmented, and usually located above or between the eyes. How Do Insects Use Antennae? Antennae serve different sensory functions for different insects. In general, the antennae might be used to detect odors and tastes, wind speed and direction, heat and moisture, and even touch. A few insects have auditory insects on their antennae, so theyre involved in hearing.à In some insects, the antennae may even serve a non-sensory function, such as grasping prey. 13 Different Shapes Because antennae serve different functions, their forms vary greatly within the insect world. In all, there are about 13 different antennae shapes, and the form of an insects antennae may be an important key to its identification. Learn to differentiate the forms of insect antennae, and it will help you improve your insect identification skills. Aristate Are Pouch-Like Aristate antennae are pouch-like, with a lateral bristle. Aristate antennae are most notably found in the Diptera (true flies). Capitate Have a Prominent Club or Knob at Their Ends Capitate antennae have a prominent club or knob at their ends. The term capitate derives from the Latin caput, meaning head. Butterflies (Lepidoptera)à often have capitate form antennae. Clavate Have a Gradual Club or Knob The term clavate comes from the Latinà clava, meaning club. Clavate antennae terminate in a gradual club or knob (unlike the capitate antennae, which end with an abrupt, pronounced knob). This antennae form is found most often in beetles, such as in carrion beetles. Filiform Are Slender and Thread-Like The term filiform comes from the Latin filum, meaning thread. Filiform antennae are slender and thread-like in form. Because the segments are of uniform widths, there is no taper to filiform antennae. Examples of insects with filiform antennae include: rock crawlers (order Grylloblattodea)gladiators (order Mantophasmatodea)angel insects (order Zoraptera)cockroaches (order Blattodea) Flabellate Look Like a Folding Paper Fan Flabellateà comes from the Latin flabellum, meaning fan. In flabellate antennae, the terminal segments extend laterally, with long, parallel lobes that lie flat against one another. This feature looks like a folding paper fan. Flabellate (or flabelliform) antennae are found in several insect groups within the Coleoptera, the Hymenoptera, and the Lepidoptera. Geniculate Are Bent or Hinged Sharply Geniculate antennae are bent or hinged sharply, almost like a knee or elbow joint. The term geniculate derives from the Latin genu, meaning knee. Geniculate antennae are found mainly in ants or bees. Lamellate Are Flattened and Nested The term lamellate comes from the Latin lamella, meaning a thin plate or scale. In lamellate antennae, the segments at the tip are flattened and nested, so they look like a folding fan. To see an example of lamellate antennae, look at a scarab beetle. Monofiliform Look Like Strings of Beads Monofiliform comes from the Latin monile, meaning necklace. Moniliform antennae look like strings of beads. The segments are usually spherical, and uniform in size. The termites (order Isoptera) are a good example of insects with moniliform antennae. Pectinate Have a Comb-Like Shape The segments of pectinate antennae are longer on one side, giving each antennae a comb-like shape. Bipectinate antennae look like two-sided combs. The term pectinate derives from the Latin pectin, meaning comb. Pectinate antennae are found mainly in some beetles and sawflies. Plumose Haveà a Feathery Appearance The segments of plumose antennae have fine branches, giving them a feathery appearance. The term plumose derives from the Latin pluma, meaning feather. Insects with plumose antennae include some of the true flies, such as mosquitoes, and moths. Serrate Look Like a Saw Blade The segments of serrate antennae are notched or angled on one side, making the antennae look like a saw blade. The term serrate derives from the Latin serra, meaning saw. Serrate antennae are found in some beetles. Setaceous Are Bristle-Shaped The term setaceous comes from the Latin seta, meaning bristle. Setaceous antennae are bristles of insects with setaceous antennae include mayflies (order Ephemeroptera) and dragonflies and damselflies (order Odonata). Stylate Terminate in a Long, Slender Point Stylateà comes from the Latinà stylus, meaning pointed instrument. In stylate antennae, the final segment terminates in a long, slender point, called a style. The style may be hairlike but will extend from the end and never from the side. Stylate antennae are found most notably in certain true flies of the suborder Brachycera (such as robber flies, snipe flies, and bee flies). Source: Triplehorn, Charles A. and Johnson, Norman F.
