ISOLATION AND IDENTIFICATION OF THE BACTERIAL COMMUNITY ASSOCIATED WITH THE ROVE BEETLE, Paederus fuscipes CURTIS (COLEOPTERA: STAPHYLINIDAE)

The rove beetle, Paederus fuscipes Curtis has caused tremendous dermatitis once unintentionally crushed against human skin due to their potent toxic released called paederin produce by the endosymbiont bacteria. The genus Pseudomonas was hypothesized to be the endosymbiont bacteria involved in the production of paederin in Paederus. However, no extensive studies have been performed to investigate the existence of other bacteria, and the relationship between the endosymbiont counts amongst male and female P. fuscipes beetles. We found that P. fuscipes harbours surprising numbers of bacteria diversity with a total of 20 different bacterial species identified. Bacillus, Serratia, Staphylococcus, and Pseudomonas bacteria were the dominated genus found in all collected beetles from all light trap locations. However, only Pseudomonas aeruginosa Migula is the medically important species and is commonly known to cause severe dermatitis lesions to humans. Our results revealed the P. aeruginosa counts cultured on Pseudomonas medium was found higher total mean bacteria counts in P. fuscipes females (2.58 x 105 ± 2.73 x 104 cell) compared to male beetles (5.68 x 104 ± 3.70 x 103 cells). We demonstrated that a large diversity of bacterial community has been isolated from both male and female P. fuscipes, however P. aeruginosa colonies were frequently detected in females compared to male beetles. These results can be used in future studies to investigate the possible impact of these bacterial counts on the concentration of paederin produced in P. fuscipes.
Outcome Based Education (OBE) Tools: A Study of EvalTools LMS

: Global developments in higher education show a shift from the traditional teacher-centered model that stresses on lectures, tests and other methods of assessments towards the technology supported learning that emphasize on what students know and can actually do. To meet this challenge a new learning model called Outcome-Based Education (OBE) emerged which was adopted by many educational institutions around the world in order to promote educational reform and renew education strategy. This model emphases on extra attention towards the evaluation of learning outcomes which has resulted in new challenges for teachers and administrators. The traditional manual paper-based process of evaluation to assess the achievement of learning outcomes in a course is usually an exhaustive process. Since the assessment and evaluation is foremost measure for educational effectiveness that is required by accreditation bodies, therefore, there was need for an organized computerized system to link all the course level assignments, quizzes and other activities for the assessment. Learning Management Systems (LMS) are such systems that facilitate the capture and storage of all course related activities like, quizzes, exams, assignments, projects etc. along with the scores and evaluation of each of these activities. EvalTools LMS is one such software that has all the features that can fulfill the requirements of OBE learning model. Keeping in view the importance of LMS in OBE model, this paper discusses EvalTools LMS and its various features.
A small dual-frequency transformer in two sections

One of the most useful transmission-line constructs is the quarter-wave transformer that is used to impedance match a line at a single frequency f/sub 0/. The feasibility of an electrically small transformer with two sections and capable of achieving ideal impedance matching at two arbitrary frequencies is demonstrated analytically. To achieve this, the exact solution to the resulting transcendental transmission-line equations for two sections is obtained with no restrictions. The parameters of the transformer are presented in explicit closed form, and are exact. The results of this study are useful for a number of practical design problems, including dual-band antennas and RF circuits in general. In particular, feasibility of ideal operation at the important first harmonic frequency 2f/sub 0/ is demonstrated.
Increasing knowledge and attitudes of adolescents related to sexual and reproductive health by using audio-visual media during the covid-19 pandemic

Adolescence is a developmental stage from the transition to adulthood. A cognitive problem that affects adolescence namely the lack of knowledge about reproductive health. The purpose of this study was to explain the effectiveness of health education using audio-visual methods on students' knowledge and attitudes about adolescent reproductive health during the COVID-19 pandemic. This research uses a quasi-experimental design. The results obtained from the 75 respondents who filled out the questionnaire showed that the attitude of the students on the pre-test score was 60,00 and the post-test was 63,45, whereas the students' knowledge on the pre-test score was 15,89 and the post-test is 17,20. From the results of the research carried out with the Wilcoxon test that the Asymp. Sig (2-tailed) is worth 0,0001 where the value is less than <0.005, therefore the hypothesis was accepted. Using audiovisual media is that it will add more real material content and will increase memory retention due to media that is much interesting and easy to remember by the individual, factors that can influence knowledge and attitudes related to reproductive and sexual health in adolescents are knowledge, attitudes and the individual's environment in processing the information obtained. Therefore there is a significant effect of health education with audiovisual methods on increasing the knowledge and attitudes of adolescents related to reproductive and sexual health.
Seasonality of the Mesoscale Inverse Cascade as Inferred from Global Scale-Dependent Eddy Energy Observations

Oceanic mesoscale motions including eddies, meanders, fronts, and filaments comprise a dominant fraction of oceanic kinetic energy and contribute to the redistribution of tracers in the ocean such as heat, salt, and nutrients. This reservoir of mesoscale energy is regulated by the conversion of potential energy and transfers of kinetic energy across spatial scales. Whether and under what circumstances mesoscale turbulence precipitates forward or inverse cascades, and the rates of these cascades, remain difficult to directly observe and quantify despite their impacts on physical and biological processes. Here we use global observations to investigate the seasonality of surface kinetic energy and upper ocean potential energy. We apply spatial filters to along-track satellite measurements of sea surface height to diagnose surface eddy kinetic energy across 60-300 km scales. A geographic and scale dependent seasonal cycle appears throughout much of the mid-latitudes, with eddy kinetic energy at scales less than 60 km peaking 1-4 months before that at 60-300 km scales. Spatial patterns in this lag align with geographic regions where an Argo-derived estimate of the conversion of potential to kinetic energy are seasonally varying. In mid-latitudes, the conversion rate peaks 0-2 months prior to kinetic energy at scales less than 60 km. The consistent geographic patterns between the seasonality of potential energy conversion and kinetic energy across spatial scale provide observational evidence for the inverse cascade, and demonstrate that some component of it is seasonally modulated. Implications for mesoscale parameterizations and numerical modeling are discussed.
The use of the Box-Cox transformation, an alternative to the quadratic production functions.

This study pleads for the use of other alternative variants, flexible from the point of view of the mathematical expression, for the production functions in the case of determining the influence of fertilizing substances on cereal production. Practically, we examine the differences from the quadratic function, corresponding to a real situation of corn fertilization for a production function obtained by the Boxâ€“Cox transformation. The values obtained are very close, but in the context of a more flexible expression, they indicate the possibility of use for fertilization optimization issues. Â
AskNow Instant Messaging: innovation in virtual reference

In late 2006, the National Library of Australia implemented a trial Instant Messaging service that ran in parallel with the AskNow chat reference service for a six month period. The trial was a resounding success, proving both a demand for an IM service and the suitability of the medium for reference service provision in a collaborative environment. The trial also allowed the collection of a significant body of data on user expectations, librarian experience and the nature of enquiries. This article begins by introducing the concept of IM and discusses the impetus for its use as a channel for reference service provision. It presents and analyses data collected from user surveys, session transcripts, usage statistics, staff surveys and other staff feedback mechanisms, and explores the issues arising from the data analysis. The article concludes by discussing the IM system architecture that the NLA is currently developing, which will allow the Library to move forward with an ongoing IM service.
Exploring environmental connection: ecological network opportunities in the Shahdagh National Park, Azerbaijan

The high growth rate of consumption of natural resources by people in the last century have seriously and negatively affected ecosystems and led to the loss of biodiversity. At present, it is important to take the necessary measures to ensure sustainable development and biodiversity conservation. Ecological networks play an important role in maintaining and controlling the stability and balance of communication between ecosystem complexes. For this purpose, the possibility of creating an ecological network that includes core areas, buffer zones, ecological corridors and restoration areas in the section of Shamakhi district of the Shahdagh National Park was explored. The designated buffer zone of the national park includes 14 villages and 1 settlement type administrative unit. Mountainous landscapes predominate in the area, and the absolute height ranges from 500-200 m. Riverbeds, intermountain depression, mountain passes, trails and forests which should be planted in the areas we offer, were considered as main factors during the construction of ecological corridors in the national park and the buffer zones. The materials obtained from the literature and our field studies, also, vector and raster data were used during the site identification. The data was processed in software such as ArcGIS 10, ERDAS Imagine, Global Mapper, Google Earth, etc. Existing ecosystems were identified, and areas were calculated in separate elements of the ecological network in the study area.

Alma mat(t)er(s): Determinants of early career success in economics

We study 6000 author-publication observations to investigate predictors of early career success in six fields of economics. Concentrating on top researchers enables us to control for the effects of ability and effort, and focusing on the start of their careers minimizes distortions from reputation feedback. Our results reveal that the most important predictor for early career success is the ranking of an author’s PhD granting institution, followed by his first placement. Our insights suggest that a counterfactual decrease in the Alma mater of a high ability author, who graduated from a top 10 university, by as little as 10 to 20 ranks, reduces his probability of getting a top 5 publication significantly by 13 percentage points. Lowering the ranking of his Alma mater by another 80 ranks decreases his chances of getting a top publication by a factor of three. Our findings suggest that the economics publication market values Alma mater signals, discounting newcomers graduating from- or working at lower ranked departments.
Subtle, intimate interfaces for mobile human computer interaction

The mobile phone is always carried with the user and is always active: it is a very personal device. It fosters and satisfies a need to be constantly connected to one's significant other, friends or business partners. At the same time, mobile devices are often used in public, where one is surrounded by others not involved in the interaction. This private interaction in public is often a cause of unnecessary disruption and distraction, both for the bystanders and even for the user. Nevertheless, mobile devices do fulfill an important function, informing of important events and urgent communications, so turning them off is often not practical nor possible. This thesis introduces Intimate Interfaces: discreet interfaces that allow subtle private interaction with mobile devices in order to minimize disruption in public and gain social acceptance. Intimate Interfaces are inconspicuous to those around the users, while still allowing them to communicate. The concept is demonstrated through the design, implementation and evaluation of two novel devices : " Intimate Communication Armband a wearable device, embedded in an armband, that detects motionless gestures through electromyographic (EMG) sensing for subtle input and provides tactile output; " Notifying Glasses a wearable notification display embedded in eyeglasses; it delivers subtle cues to the peripheral field of view of the wearer, while being invisible to others. The cues can convey a few bits of information and can be designed to meet specific levels of visibility and disruption. Experimental results show that both interfaces can be reliably used for subtle input and output. Therefore, Intimate Interfaces can be profitably used to improve mobile humancomputer interaction.

Cultivation optimization and modeling for microalgae to produce biodiesel

Microalgae has shown to be an ideal choice for biofuel industry. Algae has high oil productivity, a short growth cycle and survives in a wide variety of water sources including high salinity and waste water. For this project, four different species of marine microalgae were screened based on oil content. They were Dunaliella tertiolecta(CCMP364), Nannochloropsis gaditana (CCMP527), Tetraselmis sp (CCMP 908) and Nannochloropsis salina (CCMP1776). Experimental results showed that CCMP 527 and 1776 strains had higher lipid content and better fatty acids profile than the other two. Further investigations were carried on CCMP 527 in order to maximize biomass productivity and lipid content. Nutrients, salinity, pH, temperature, light intensity and aging of the culture can all affect both lipid content and fatty acid profile and were investigated. Nutrient stress is the easiest way to manipulate lipid composition and increase lipid content. Hence, various carbon and nitrogen sources were investigated to determine the range and amount of substrates that may be feasible for cultivation. For supplying lipid for biodiesel production, the optimum culture conditions for strain Nannochloropsis gaditana are using CO2 enriched air bubbling, f/2-Si medium, pH control, and nitrate as the nitrogen source. Use of other fertilizers is feasible as well, however, the nitrogen source greatly affects lipid productivity, but trace amounts of organics in ground water do not. A model which predicts cell growth, nitrogen concentration, and lipid yield in batch systems is developed that is applicable for low nitrogen conditions. Plus, a sensitivity analysis of three major parameters was done to validate how variations in these key
Handling constraints with an evolutionary tool for scheduling oil wells maintenance visits

Oil exploitation and transportation are very important activities for the development of industrial society. However, these activities are generating risks that are translated into accidental or chronic contaminations that directly affect the ecosystem. It is important that oil companies carry out correct maintenance of their oil fields. For example, the scheduling of visits to oil wells is a critical problem that has to be addressed in this scenario. To do that, an efficient tool called PAE was formerly proposed that is based on an evolutionary algorithm which obtains better schedules than those obtained by experts. In this article, an extension of PAE is presented to solve a constrained version of the maintenance problem. This new version of PAE is studied under the application of a set of constraint-handling techniques based on penalty functions and repair algorithms. The results and comparisons demonstrated that PAE, using a repair algorithm, required less computational effort (evaluations) with the same quality of solutions for the set of instances used. Details of implementation, results and benefits are presented.
Sea Ice Variability and Trends in the Western Indian Ocean Sector of Antarctica During the Past Two Centuries and Its Response to Climatic Modes

Antarctic sea ice is a critical component of the ocean‐climate system. Sea ice concentration (SIC) records of various oceanic sectors of Antarctica available since 1979 reveal dramatic changes in recent years; however, there is no consensus yet on drivers of sea ice variability, changes and their future projections. The lack of long‐term SIC records has impeded the quantification of sea ice variability, trends and various forcing factors and mechanisms. Here, we present a long‐term SIC record (1809−1993 CE) for the Western Indian Ocean Sector (WIOS) of Antarctica derived from a new ice core oxygen isotope (δ18O) record together with three available records from Dronning Maud Land (DML), East Antarctica. This long‐term SIC record at annual resolution reveals a significant decline during 1830–1884 CE with a rate of 0.58% ± 0.12% decade−1 followed by moderate increase during 1927–1993 CE with a rate of 0.24% ± 0.11% decade−1. Current satellite‐derived SIC records reveal an increase of 2.59 ± 0.86% decade−1 during 1994–2014 CE, which is unprecedented over the last two centuries as determined by the ice core‐derived SIC record. The satellite and ice core combined SIC record (1809−2019 CE) also reveals a significant increase in interannual variability at El Niño Southern Oscillation band and decadal variability at 16–32 years band in the last few decades. Our investigation suggests that wind‐driven sea‐ice dynamics associated with switching phases of Southern Annular Mode and remote teleconnections of Pacific oscillations largely control the interannual to decadal sea ice variability in this region.
Nano-optical devices and integration based on nanopattern replications and nanolithography

We developed a nano-manufacturing platform based on wafer level nano-replication with mold and nano-pattern transfer by nano-lithography. The nano-replication process, which based on imprinting a single-layer spin-coated UV curable resist, achieved excellent nano-patterning fidelity and on-wafer uniformity with high-throughput. Nano-optic devices, such as, quarter wave plates and polarizers, were manufactured with the nano-manufacturing platform. Excellent wafer level performance and yield were achieved. The developed technology is suitable for high-throughput and low cost manufacturing needs for commercializing nano-structure based optical devices and integrated optical devices.
Computational fluid dynamics study and evaluation of different personalized exhaust devices

This article investigates the performance of three different types of personalized exhaust devices. A top-personalized exhaust, which is a round device just above the human head; a shoulder-personalized exhaust, which consists of two local exhaust devices installed at the chair just above shoulder level; and a chair-personalized exhaust, which is at the upper part of a chair just behind the human head, were simulated, evaluated, and compared numerically using the computational fluid dynamics method. Two seated occupants representing healthy and infected manikins equipped with two types of personalized ventilation devices in a simulated consulting room in a healthcare center were modeled. Two indices—personalized exposure effectiveness and inhaled fraction—were introduced to evaluate the improvement of general inhaled air quality after adding different types of personalized exhaust devices and to compare the performance of different kinds of personalized exhaust devices with respect to the healthy manikin's exposure to exhaled contaminated air. The computational fluid dynamics models were validated with a set of experiments conducted in an environmental chamber. The results indicate that all the three personalized exhaust devices might be able to reduce the transmission of exhaled air between occupants. The lowest inhaled fraction was achieved by the combination of a vertical desk grill and a top-personalized exhaust. However, only the shoulder-personalized exhaust device has the potential to improve the amount of personalized ventilation air in the inhaled air.
Lightweight Cellulose Nanofibril/Reduced Graphene Oxide Aerogels with Unidirectional Pores for Efficient Electromagnetic Interference Shielding

Lightweight and compressible aerogels have been widely considered as promising materials for electromagnetic interference (EMI) shielding. Herein, a lightweight cellulose nanofibril/reduced graphene oxide carbon aerogel fabricated by unidirectional freeze‐drying and pyrolysis processes is reported. The results show that the aerogels with unidirectionally aligned pores possess better compression resilience and EMI shielding performance in the radial direction. The unidirectional aerogel with low density (≈0.0058 g cm−3) exhibits a high EMI shielding effectiveness (SE) of ≈33 dB at 8.2–12.4 GHz and a specific EMI SE of 5759 dB cm3 g−1. Therefore, the fabricated aerogel demonstrates a promising potential in the field of next‐generation EMI shielding materials.
Perceptual Control: Management Insight for Problem Solving
