Functional Approach in Teaching and Learning Plane Trigonometry
Authors: Magat Marita Salvo
Published: July 2018

Functional approach is both content and learner based approach of teaching Plane Trigonometry.  As a content-based approach, it is anchored more on the concepts of circles and their applications rather than the concepts of angles.  As a learner-based approach, it is based on Sticht theory of functional context learning which stresses the importance of making learning relevant to the experiences of the learners and their work context.

This study investigated the effect of functional approach in the mathematics performance of college students.  It likewise looked into its effectiveness in developing conceptual understanding, computation and problem solving skills and the factors associated with the development of these skills.  It employed the quasi-experimental method specifically the non-equivalent pretest-posttest control group design.  Findings revealed that the functional approach is more effective in raising the performance of students to the standard level in conceptual understanding, computation and problem solving skills than the traditional approach. It was also found out that factors such as previous ratings in mathematics, scholastic aptitude, attitude towards mathematics and gender are associated with development of the three mathematics skills.  Income of the family is not associated with mathematics skills development.  Functional approach in teaching Plane Trigonometry is recommended since it is anchored on the concepts of circles and circular functions which offers sound background materials for the study of higher mathematics and a high potential for the development of conceptual, computational and problem solving skills because it make use of students’ daily work context.

Influence of Attitude, Cooperative and Inquiry Instructional Strategies on the Academic Performance of Students in Basic Science and Mathematics in Katsina, Nigeria
Authors: Sa’adu Matazu Dr. Suleiman , Julius Elizabeth
Published: July 2018

Investigating the effects of cooperative learning as an instructional strategy for teaching basic science and mathematics to junior secondary school students in Katsina state was the focus of this study. Equally, it also looked at how gender affect students' performance and attitude in basic science and mathematics when cooperative learning was used as an instructional strategy. Quasi-experimental design was used in the study with 240 students as sample selected purposively. Findings of the study revealed that students taught using cooperative learning strategy performed higher than those taught using inquiry learning strategy; there was an insignificant difference in performance between the male and female students in the cooperative learning group. The students in cooperative learning group show a more positive attitude towards basic science and mathematics than those in inquiry classroom learning. On the bases of these findings, it was recommended that cooperative learning strategy be adopted by all secondary school Basic Science and Mathematics teachers as an effective learning strategy in order to improve students’ performance and positive attitude towards science and mathematic

Published: July 2018

Este artigo apresenta as etapas do projeto e implementação de um controlador digital preditivo para regular as correntes de um motor CC de ímãs permanentes sem escovas (BLDC - Permanent Magnets Brushless DC Motor) trifásico à três fios. O projeto e sintonia de controladores lineares, como o PI-SRF (PI no sistema de coordenadas síncrono), é uma tarefa difícil devido às formas de onda não senoidais das FEM internas e das correntes de acionamento dos motores BLDC. A complexidade desta tarefa aumenta quando se considera a faixa de variação de velocidade dos motores usados nos veículos elétricos. Os controladores digitais preditivos têm sido utilizados com sucesso para regular correntes de conversores CC-CC. Será mostrado que pode-se usar um controlador digital preditivo para regular as correntes do sistema de acionamento. Resultados experimentais e de simulação para uma aplicação em um motor BLDC trifásico de 5 kW / 48 V são apresentados para demonstrar a viabilidade da proposta. O algoritmo de controle do sistema de acionamento do motor BLDC foi implementado em um DSP TMS320F28335 da Texas Instruments. Será apresentada uma metodologia para compensar os atrasos dos circuitos de disparo e amostragem, bem como as quedas de tensão do inversor no algoritmo do controlador proposto.

Naming Strategies and Ethnobiological Nomenclature in Kakataibo (Panoan, Peru)
Authors: Zariquiey Roberto
Published: July 2018

The present paper describes and illustrates the main naming strategies attested in a lexical database of 1233 Kakataibo names of plant and animals. Seven naming strategies are proposed for Kakataibo ethnobiological nomenclature: coining, morphological derivation, borrowing, ethnobiological polysemy, compounding and grammatical nominalization (the latter two being exclusively associated with lexically complex forms). Kakataibo ethnobiological terminology overally follows the general word-formation patterns available in the language, but it will be argued that some types of compounds and grammatical nominalizations found in the database are constraint to names of plants and animal. Indeed, one particular type of lexicalized grammatical nominalization seems to be cross-linguistically unusual.

Development of a High-Temperature-Resistant Polymer-Gel System for Conformance Control in Jidong Oil Field
Authors: Zhu Daoyi , Hou Jirui , Wei Qi , Chen Yuguang
Published: July 2018

The PG Reservoir in Jidong Oil Field is at a depth of approximately 4500 m with an extremely high temperature of approximately 150°C. The average water cut has reached nearly 80%, but the oil recovery is less than 10% after only 2 years of waterflooding process. It is of great importance to develop a high-temperature-resistant plugging system to improve the reservoir conformance and control water production. An in-situ polymer-gel system formed by the terpolymer and a new crosslinker system was developed, and its properties were systematically studied under the condition of extremely high temperature (150°C). Suitable gelation time and favorable gel strength were obtained by adjusting the concentration of the terpolymer (0.4 to 1.0%) and the crosslinker system (0.4 to 0.7%). An increase of polymer and crosslinker concentration would decrease the gelation time and increase the gel strength. The gelant could form continuous 3D network structures and thus have an excellent long-term thermal stability. The syneresis of this gel system was minor, even after being heated for 5 months at the temperature of 150°C. The gel system could maintain most of the initial viscosity and viscoelasticity, even after experiencing the mechanical shear or the porous-media shear. Core-flow experiments showed that the gel system could have great potential to improve the conformance in Jidong Oil Field.

Core Ideas

Fungicide in‐furrow and starter fertilzer individually did not increase yield.

Fungicide and starter fertilizer combined in‐furrow increased yield marginally.

Fungicide and starter fertilizer in‐furrow may not be economical without disease.

Planting into cool and wet conditions exposes soybean [Glycine max (L.) Merr.] seed and seedlings to pathogens that may reduce plant populations, resulting in lower yield. Recently, fungicides have been labeled for in‐furrow applications and marketed to provide additional broad‐spectrum protection from soilborne fungi and enhance seedling vigor. Additionally, liquid fertilizers have been promoted recently as a carrier for fungicides to improve yield in some soybean producing areas in the United States. The objective of this study was to evaluate the effect of a fungicide, starter fertilizer, and a combination of fungicide and starter fertilizer on soybean yield. Field experiments were laid out in Arkansas, Indiana, Iowa, and Mississippi in the United States and Ontario, Canada, with a total of 14 site‐years. A positive yield response was observed with the fungicide and starter fertilizer treatment combination in Arkansas in 2014; however, there was no effect of treatment on soybean yield at any other location or year. Overall, a yield benefit of 1.6 bu/acre (107.6 kg/ha) (P = 0.02) with the fungicide and starter fertilizer treatment was observed across all locations when combined using meta‐analysis. In conclusion, our study suggests that the prophylactic application of fungicide and starter fertilizer may not be profitable without the risk of soilborne diseases and nutrient deficiencies.

Bahiagrass (Paspalum notatum Flüggé) and rhizoma peanut (RP, Arachis glabrata Benth.) are widely used in Florida, and growing them in association may decrease the need for N fertilization. This study evaluated herbage responses of mixed RP–bahiagrass swards in comparison with their monocultures. The eight treatments were two bahiagrass entries (‘Argentine’ and DF9, receiving 90 kg N ha−1 harvest−1) and two RP entries (Ecoturf and Q6B) in monoculture and the combinations of each bahiagrass with each RP (Argentine–Ecoturf, Argentine–Q6B, DF9–Ecoturf, and DF9–Q6B). There was no difference in total herbage accumulation (HA) in 2015. In 2016, total HA was greatest for Argentine + N (9630 kg dry matter [DM] ha−1), followed by the mixture Q6B–DF9 (5910 kg DM ha−1). Mixtures produced as much biomass as RP monocultures and DF9 + N. In mixtures, Argentine was the most competitive bahiagrass, whereas Q6B was the most competitive RP. Crude protein concentration of DF9 in the mixture with Q6B was similar to that of N‐fertilized DF9. The total aboveground N was usually greatest in RP monocultures (50–53 kg N ha−1 harvest−1). Percentage of N derived from the atmosphere increased by 22% in Q6B from 2015 to 2016. Biological N2 fixation ranged from 11 (Ecoturf–Argentine) to 44 kg N ha−1 harvest−1 (Ecoturf and Q6B). Entry growth habit affected the proportion of each component in the sward, and this information is crucial when combining warm season grasses and legumes. Rhizoma peanut will add N to bahiagrass systems and improve forage nutritive value but have less HA than heavily fertilized grass.
Statistical Characterization of the Root System Architecture Model CRootBox
Authors: Schnepf A. , Huber K. , Landl M. , Meunier F. , Petrich L. , Schmidt V.
Published: July 2018

Core Ideas

The stochasticity of 3D root architecture models needs to be recognized by statistical analysis.

Probability density functions, regression, and correlation analyses reveal the impact of model input parameters on different CRootBox measures.

Distributions of ratios of root system measures are highly asymmetric.

Multivariate approaches (copulas) are envisioned for future root architecture model analysis.

The connection between the parametrization of three‐dimensional (3D) root architecture models and characteristic measures of the simulated root systems is often not obvious. We used statistical methods to analyze the simulation outcome of the root architecture model CRootBox and built meta‐models that determine the dependency of root system measures on model input parameters. Starting with a reference parameter set, we varied selected input parameters one at a time and used CRootBox to compute 1000 root system realizations as well as their root system measures. The obtained data sets were then statistically analyzed with regard to dependencies between input parameters, as well as distributions and correlations between different root system measures. While absolute root system measures (e.g., total root length) were approximately normally distributed, distributions of ratios of root system measures (e.g., root tip density) were highly asymmetric and could be approximated with inverse gamma distributions. We derived regression models (meta‐models) that link significant model parameters to 18 widely used root system measures and determined correlations between different root system measures. Statistical analysis of 3D root architecture models helps to understand the impact of input parametrization on specific root architectural measures. Our developed meta‐models can be used to determine the effect of parameter variations on the distribution of root system measures without running a full simulation. Model intercomparison and benchmarking of root architecture models is still missing. Our approach provides a means to compare different models with each other and with experimental data.
Berberine Alleviates Amyloid-Beta Pathology in the Brain of APP/PS1 Transgenic Mice via Inhibiting β/γ-Secretases Activity and Enhancing α-Secretases
Authors: Cai Zhiyou , Wang Chuanling , He Wenbo , Chen Yi
Published: July 2018

Background:

Berberine (BBR) has neuroprotective effects on many brain diseases, including
Alzheimer’s disease (AD). Amyloid -beta (Aβ) senile plaque is the most classical pathological
hallmarks of AD. Aβ produces from a sequential cleavage by β-secretase (beta-site amyloid precursor
protein cleaving enzyme 1, BACE1) and γ -secretase. The aim of our work was to investigate
whether the neuroprotective effects of BBR on AD is related to inhibiting Aβ pathology.

Method:

The cognitive function of mice was assessed by the Morris water maze (MWM) test.
The Aβ levels were determined by enzyme linked immunosorbent assay; the expression of APP,
sAPPα, ADAM10 and ADAM17, sAPPβ and BACE1 was detected by Western blotting; and the activity
of γ -secretase complex (NCT, PS1, Aph-1α and Pen-2) was determined by Western blotting and
immunohistochemistry.

Results:

BBR improved learning and memory deficits of APP/PS1 mice. BBR decreased Aβ levels in
the hippocampus of APP/PS1 mice. BACE1 and sAPP -β levels in the BBR-treated groups were significantly
reduced in the hippocampus of AD mice. BBR markedly decreased the expression of PS1,
Aph-1α and Pen-2, but had no effect on NCT. The levels of sAPPα, ADAM10 and ADAM17 in the
hippocampus of BBR-treated mice significantly increased, compared with the control ones (P<0.05).

Conclusion:

BBR inhibits the activity of β/γ-secretases, enhances α-secretases, and lowers the Aβ level
in the hippocampus of AD mice, and improves Alzheimer’s-like cognitive impairment.
Modulation of the Cannabinoid System: A New Perspective for the Treatment of the Alzheimer’s Disease
Authors: Talarico Giuseppina , Trebbastoni Alessandro , Bruno Giuseppe , de Lena Carlo
Published: July 2018

The pathogenesis of Alzheimer’s disease (AD) is somewhat complex and has yet to be fully understood. As the effectiveness of the therapy currently available for AD has proved to be limited, the need for new drugs has become increasingly urgent. The modulation of the endogenous cannabinoid system (ECBS) is one of the potential therapeutic approaches that is attracting a growing amount of interest. The ECBS consists of endogenous compounds and receptors. The receptors CB1 and CB2 have already been well characterized: CB1 receptors, which are abundant in the brain, particularly in the hippocampus, basal ganglia and cerebellum, regulate memory function and cognition. It has been suggested that the activation of CB1 receptors reduces intracellular Ca concentrations, inhibits glutamate release and enhances neurotrophin expression and neurogenesis. CB2 receptors are expressed, though to a lesser extent, in the central nervous system, particularly in the microglia and immune system cells involved in the release of cytokines. CB2 receptors have been shown to be upregulated in neuritic plaque-associated microglia in the hippocampus and entorhinal cortex of patients, which suggests that these receptors play a role in the inflammatory pathology of AD. The role of the ECBS in AD is supported by cellular and animal models. By contrast, few clinical studies designed to investigate therapies aimed at reducing behaviour disturbances, especially night-time agitation, eating behaviour and aggressiveness, have yielded positive results. In this review, we will describe how the manipulation of the ECBS offers a potential approach to the treatment of AD.
A Review on Possible Therapeutic Effect of Nigella sativa and Thymoquinone in Neurodegenerative Diseases
Authors: Samarghandian Saeed , Farkhondeh Tahereh , Samini Fariborz
Published: July 2018

Background & Objective: Medicinal plants have attracted great attention in the recent years
and is increasingly applied instead of the chemical drugs. Several documents showed that herbal medicine
traditionally and clinically applied in the cure and prevention of several diseases. In the recent
years, different medicinal plants and their main components have been chosen in neurological therapy.
The less toxic effects, availability, and lower price of medicinal plants versus synthetic substances
make them as excellent and simple selection in the treatment of nervous diseases. Nigella sativa (N.
Sativa) L. (Ranunculaceae), well recognized as black cumin, has been utilized as a medicinal plant that
has a strong traditional background. Thymoquinone (TQ) is one of the main active components of the
volatile oil of N. sativa seeds and most effects and actions of N. Sativa are mainly related to TQ. The
several pharmacological properties of N. sativa and TQ have been found, for example; anti-tumor,
anti-microbial, anti-histaminic, immunomodulatory, anti-inflammatory, and anti-oxidant effects. Many
reviews have investigated this valuable plant and its components, but none of them focused on their neuroprotective
effects. Therefore, the aim of the present review was to show comprehensive and
neuropharmacological properties of N. sativa and TQ. In this review, various studies on scientific databases
regarding the effects of N. sativa and TQ in neurological diseases have been introduced. Studies
on the neuroprotective effects of N. sativa and TQ which were published between1979 and 2018, were
searched using various databases. The results of these studies showed that N. sativa and TQ have the
protective effects against neurodegenerative diseases, including; Alzheimer, depression, encephalomyelitis,
epilepsy, ischemia, Parkinson, and traumatic brain injury have been discussed in the cell lines
and experimental animal models. Although there are many studies indicating the beneficial actions of
this plant in the nervous system, the number of research projects relating to the human reports is rare.

Conclusion:

Therefore, better designed clinical trials in humans are needed to confirm these effects.

Mount Merapi eruption in 2010 that discharged more than 130 million m3 of landfill material brought impact on the thickness and height of caused damage to the yard and agricultural land. After mining heap of materials in the form of boulders, stones, gravels, and gravel to sand, RLKT activities (Rehabilitation and Soil Conservation) needs to be pursued to mobilize the people in the village of Kepuharjo. Cooperation between BPTKPDAS Solo with Kepuharjo Village community is incorporated in FPL PALEM (Environmental Care Forum Merapi Slope-Nature Lovers) by performing RLKT barrier in the form of grass planting (Grass Barriers) and manure treatment with the observation of surface erosion due to the effects of wind on the rorak. The purpose of this study was to quantify the effectiveness of grass barrier for wind erosion control at the land formerly affected by eruption at Merapi Mountain. The results show that the combination of grass and manure was able to suppress the erosion up to 88%. Effective rorak types were derived from bucket and it is not recommended that rorak includes a stick for a heap of unstable soil particles. Therefore, the usage of plastic is not suggested as it is easily torn. ABSTRAKBencana erupsi Gunung Merapi tahun 2010 telah mengeluarkan material lebih dari 130 juta m3 dan berdampak pada penimbunan material yang tebal dan tinggi, sehingga menyebabkan kerusakan lahan pekarangan dan pertanian.

Представлены результаты экспериментальных измерений остаточных напряжений в элементах рельса, измеренных электромагнитно-акустическим структуроскопом СЭМА с использованием метода акустоупругости. Оценка внутренних напряжений произведена также в отдельных элементах рельса. Настройка чувствительности структуроскопа СЭМА и определение коэффициента акустоупругой связи выполнены в лабораторных условиях путем создания в отрезке рельса напряженного состояния одноосного сжатия в направлении продольной оси на испытательной машине Instron 300DX. Отмечена высокая чувствительность и достоверность измерений с погрешностью определения механических напряжений до 2 МПа и соответствие зарегистрированных структуроскопом механических напряжений нагрузке рельса, реализуемой на стенде. Остаточные напряжения, определяемые акустоупругим методом по измеряемой разнице времени пробега двух ортогонально поляризованных сдвиговых волн на участке от головки до подошвы и обратно, являются усредненными по сечению рельса и несут информацию о величине продольных напряжений в рельсе. Диапазон разброса измеренных в лаборатории остаточных напряжений в отрезках рельсов составил 49…67 МПа. С ростом сжимающей нагрузки происходит уменьшение скорости головной волны на всех измеряемых участках рельса. Для относительной оценки остаточных напряжений в отдельных элементах рельса выполнены измерения скорости распространения акустических волн по головке, шейке и подошве, показавшие, что остаточные напряжения в продольном направлении рельса, как правило, носят сжимающий характер для головки и растягивающий - для шейки.

С целью оценки качества крепления монтажных выводов танталовых объемно-пористых конденсаторов и для рассмотрения необходимости и целесообразности проведения своевременных корректирующих и предупреждающих мероприятий проведен комплексный контроль качества приварки выводов танталовых конденсаторов по методике системного межэтапного комплексного анализа качества танталовых конденсаторов на основе анализа претензионных изделий с учетом конструкторско-технологического, производственного и человеческого факторов. По статистическому анализу возращенных изделий выявлена необходимость рассмотрения качества приварки катодного вывода, и с использованием метода полного факторного эксперимента на операции «приварка катодного вывода к корпусу конденсатора» для двух различных типов конструкций вывода исследовано количественное влияние характеристик технологического процесса с целью выявления режимов, наиболее эффективно воздействующих на качество сварочного соединения. Проведен многофакторный эксперимент, в результате которого построена регрессионная модель качества процесса сварки катодного вывода к корпусу танталового конденсатора и выявлена зависимость от энергетических режимов сварки. Обнаружено сильное влияние на качество выполнения операции токового значения сварки и давления на свариваемые поверхности. Область подачи инертного газа также вносит свой вклад в температурное поле зоны сварки, но в меньшей степени по сравнению с параметрами режима сварки. На основании результатов апробации можно заключить, что методика системного межэтапного комплексного анализа качества танталовых конденсаторов может быть применима для оценки качества танталовых конденсаторов как на этапе производства - для совершенствования технологических процессов, на этапе доработки конструкции, так и на этапе эксплуатации - для удовлетворения требований потребителей, и может дать экономический эффект от снижения доли возвращаемых конденсаторов, подлежащих замене. Комплексный контроль по совокупности параметров на стадии производства, испытаний и эксплуатации позволяет исключить попадание потребителю некачественной продукции.

Authors: Rempel P V , Borisov A P
Published: July 2018

Рассмотрен актуальный вопрос использования нерегламентированных возможностей сетей Wi-Fi и создания программно-аппаратного комплекса для развертывания локальной системы позиционирования объектов, основанной на измерении интенсивности принимаемого сигнала (RSSI). Система может внедряться как в уже существующую инфраструктуру Wi-Fi, так и специально спроектированную. Для расчета координат использовался алгоритм Weighted centroid (центр масс), который вычисляет координату агента как линейную комбинацию координат точек доступа с учетом мощности сигналов, в качестве характеристики веса. Местоположение объекта, оснащенного специальной меткой, отображается на персональном компьютере пользователя в режиме реального времени. Данные от метки передаются по Wi-Fi. Применение акселерометра в данной системе позволяет решить актуальную для подобного рода систем проблему энергосбережения. Другая задача, которую помогает решить акселерометр, - определение падения объекта, в случае которого на устройство управления отправляется специальный сигнал. Погрешность определения местоположения при трех точках достигает 5 метров. При увеличении количества точек происходит увеличение точности позиционирования. При этом при использовании 6 точек погрешность в определении местоположения уменьшается до 1,5 метров.

Authors: Giesey Rachel , Narively Doria , Mostow Eliot , Mullen Chanda
Published: July 2018

Background and Objectives: Dermatology is often an overlooked and underemphasized area of training in postgraduate primary care medical education, with an abundance of dermatological educational resources available, but no clear guidelines on how to best take advantage of them. The objective of this study was to develop a dermatology digital tool kit designed to describe, evaluate, recognize, and manage (DERM) common dermatological conditions in primary care residency education and to evaluate potential improvement in clinical confidence.
Methods: A total of 14 family medicine (FM) and 33 internal medicine (IM) residents were given the DERM tool kit to complete over 7 weeks. Effects on residents’ self-reported comfort with dermatology and resources used were measured by voluntary anonymous surveys distributed before and after DERM completion.
Results: A response rate of 100% (14/14) for FM residents and 52% (17/33) for IM residents was achieved. The majority of residents (61%) recalled minimal dermatology education—less than 2 weeks—in medical school and 71% agreed that there is not enough dermatology in their residency curriculum. A statistically significant increase in resident comfort with describing (P=0.002), recognizing and diagnosing (P<0.001), and managing (P=0.001) dermatologic conditions was observed postcompletion. Residents reported they would recommend this tool to other primary care residents.
Conclusions: Implementing the DERM digital tool kit is feasible with primary care residents and appears to improve comfort with describing, recognizing and diagnosing, and managing dermatologic conditions.

This study was aimed at analyzing the Indonesian translation of spelling, punctuation, and grammatical errors made by autistic character in Flower for Algernon novel. It also analyzes Â translation techniques, methods, ideology, qualities of the translation. The method applied was descriptive-qualitative with the data in the form of translated words and phrases indicating spelling, punctuation and grammatical errors made by the autistic character. The primary data sources were Flower for Algernon novel along with its translation version in Indonesian. Meanwhile, the secondary data sources were informants who gave information on the accuracy, acceptability, and readability of translation. The process of collecting data used documentation, questionnaire distribution, and focus group discussion (FGD) technique whereas the sampling technique applied is purposive sampling. The findings of this research show that there are 309 data of words containing spelling, punctuation and grammatical errors. Four translation techniques are used by translator namely graphology normalizations, established equivalent, compensation, and deletion. The translation method used tends to be established equivalent with domestication ideology. The translation of words with errors by graphology normalization techniques produced accurate translations with decreases in acceptability. This is because the translator removes the autism markers from the source language to the target language.

The focus of the present study was to examine the effect of canal bank filtration on the quality of water and the geological settings along the banks of canals at the shallow depth aquifers. The four Model wells were drilled at different locations of the Line channel, Pinyari and phulali canals in the study area. The samples of soil were collected throughout drilling of the model wells for the analysis of grain size distribution .In addition to this, canal water and model well water samples were collected and analyzed for the water quality characteristics during winter and summer seasons. The analysis of soil and water samples reveals that the ground water is influenced by the grain size distribution, hydraulic conductivity and the location of the model Wells. The model well that has higher percentage of 0.075 mm of grain size distribution(hydraulic conductivity between 10-25 ft/day) was more suitable for the filtration of the canal water through its banks, followed by 0.15 mm of grain size distribution (hydraulic conductivity > 25ft/ day). Moreover, the present study also shows that the canal water filtration is suitable in terms of total alkalinity, nitrate-nitrogen, total iron and pH to get the potable water at the location near upstream of the canal, especially in the summer season.

Libraries as a service provider to the user that needs fast, easy, and efficient services. Optimization of the services performed by the application of information technology such as utilizing barcode technology for the library system. Along with the development, there were some shortcomings in the use of barcode technology. Barcode technology can be replaced by RFID (Radio Frequency Identification) in order to further improve the operational and library services. RFID has some advantages over the barcode system is the possibility of data can be read automatically without regard to alignment readings, past the non conductor materials like cardboard paper with access speeds of several hundred tags per second at a distance of several meters. The advantages and capabilities of RFID can be applied in a library system in the inventory, self-service, and security so as to generate optimal library services more than manual systems or even a barcode system. Utilization of RFID technology in the library and then combined with technology Telegram Bot API as a medium to facilitate user access such as notification, accessing history, and others.

Published: July 2018

Scientific article reading is an important competence for undergraduate students in sciences. To help acquire this skill we chose to propose students a poster session with peer evaluation. Students are grouped in teams to which subjects are assigned. Each team prepares a poster during the semester and prints it before the exam. Students then enter a rotation system in which they alternatively present their poster to their peers and one teacher, or evaluate the posters of other groups. Each session is composed of a presentation, questions and evaluation. The evaluation is performed both by the teachers and the peers. Students are also evaluated for their ability to evaluate their peers, comparing their evaluations to those performed by others (teachers and/or peers). The evaluation is normalised thanks to a dedicated evaluation grid. After 2 years of manual management, the need to scale up our approach to larger cohorts of students lead to the development of a digital system. This article details our motives and method/protocol. Finally observations, limits and improvements are reported.
