Published: November 2020

Microbial communities promptly respond to the environmental perturbations, especially in the Arctic and sub-Arctic systems that are highly impacted by climate change, and fluctuations in the diversity level of microbial assemblages could give insights on their expected response. 16S rRNA gene amplicon sequencing was applied to describe the bacterial community composition in water and sediment through the sub-Arctic Pasvik River. Our results showed that river water and sediment harbored distinct communities in terms of diversity and composition at genus level. The distribution of the bacterial communities was mainly affected by both salinity and temperature in sediment samples, and by oxygen in water samples. Glacial meltwaters and runoff waters from melting ice probably influenced the composition of the bacterial community at upper and middle river sites. Interestingly, marine-derived bacteria consistently accounted for a small proportion of the total sequences and were also more prominent in the inner part of the river. Results evidenced that particular conditions occurring at sampling sites (such as algal blooms, heavy metal contamination and anaerobiosis) may select species at local scale from a shared bacterial pool, thus favoring certain bacterial taxa. Conversely, the few phylotypes specifically detected in some sites are probably due to localized external inputs introducing allochthonous microbial groups.
In-Channel Managed Aquifer Recharge: A Review of Current Development Worldwide and Future Potential in Europe
Authors: Standen Kathleen , Costa Luís R. D. , Monteiro José-Paulo
Published: November 2020

Managed aquifer recharge (MAR) schemes often employ in-channel modifications to capture flow from ephemeral streams, and increase recharge to the underlying aquifer. This review collates data from 79 recharge dams across the world and presents a reanalysis of their properties and success factors, with the intent of assessing the potential of applying these techniques in Europe. This review also presents a narrative review of sand storage dams, and other in-channel modifications, such as natural flood management measures, which contribute to the retardation of the flow of flood water and enhance recharge. The review concludes that in-channel MAR solutions can increase water availability and improve groundwater quality to solve problems affecting aquifers in hydraulic connection with temporary streams in Europe, based on experiences in other parts of the world. Therefore, to meet the requirements of the Water Framework Directive (WFD), in-channel MAR can be considered as a measure to mitigate groundwater problems including saline intrusion, remediating groundwater deficits, or solving aquifer water quality issues.

Published: November 2020

Relying on the results of multivariate analysis of the re-analysis case studies from the BaltCoast project, specific features of integrated coastal management (ICM) approaches in Estonia, Latvia, Lithuania, and the Kaliningrad Oblast of the Russian Federation are highlighted in this paper. Eleven Eastern Baltic ICM case studies have been re-analyzed in-depth, which was the main focus of the present paper, covering a wide range of coastal landscapes, themes, policy issues, and ICM approaches. Five principal components explaining 84.86% of the total variance of ICM factor scores have been elicited by calculating rotation sums of squared loadings: (1) Stakeholder Involvement; (2) Research Base; (3) Planning Consistency; (4) Policy Environment, and (5) Development of Plans/Strategies. A truly dedicated involvement of a wide range of stakeholders throughout all process stages showed to be critical for further successful advance of ICM processes and principles based on the systems approach in the Baltic States and the Russian Federation.
Lumped Approach for Reactive Transport of Organic Compound Mixtures through Simulated Aquifer Sands in Lab-Scale Column Tests
Authors: Joo Jin Chul , Moon Hee Sun , Chang Sun Woo
Published: November 2020

The feasibility of the lumped approach for reactive transport of 12 organic compounds in mixtures through simulated aquifer sands with different organic carbon content (foc) within soil columns was evaluated. From direct measurements of effluent samples and temporal and spatial pore-water concentration profiles within soil columns, 12 organic compounds in mixtures were sorbed to different extents due to the different dependence of sorption on foc. Considering the tradeoff between accuracy and simplicity, four, five, and six pseudocompounds were determined for simulated aquifer sands with foc of 0.006%, 0.051%, and 0.221%, respectively, to approximate the reactive transport of 12 organic compounds in mixtures. Each pseudocompound presented obviously different reactive transport behavior in terms of both sorption capacity and nonlinearity, indicating that each pseudocompound contained components with relatively similar sorption capacities and nonlinearity. Similar to the results from batch equilibrium sorption tests, log Koc can be used as the a priori grouping criterion, although the relative contributions of different forces to the overall sorption may differ for different composition of organic mixtures and foc values of aquifer sands. Finally, the assignment of the Freundlich sorption parameters of pseudocompounds using averages of Freundlich sorption parameters of their components led to reasonable prediction for reactive transport of organic compounds in mixtures through the soil columns. Further study is warranted to evaluate the effective coupling between lumped approach and reactive transport model using complex multicomponent mixtures within heterogeneous subsurface systems.
Optimization Assessment of Projection Methods of Climate Change for Discrepancies between North and South China
Authors: Lun Yurui , Liu Liu , Wang Ruotong , Huang Guanhua
Published: November 2020

Downscaling methods have been widely used due to the coarse and biased outputs of general circulation models (GCMs), which cannot be applied directly in regional climate change projection. Hence, appropriate selection of GCMs and downscaling methods is important for assessing the impacts of climate change. To explicitly explore the influences of multi-GCMs and different downscaling methods on climate change projection in various climate zones, the Heihe River Basin (HRB) and the Zhanghe River Basin (ZRB) were selected in this study to represent the north arid region and the south humid region in China, respectively. We first evaluated the performance of multi-GCMs derived from Coupled Model Inter-comparison Project Phase 5 (CMIP5) in the two regions based on in-situ measurements and the 40 year European Centre for Medium-Range Weather Forecasts (ECMWF) Re-Analysis (ERA-40) data. Subsequently, to construct appropriate climate change projection techniques, comparative analysis using two statistical downscaling methods was performed with consideration of the significant north–south meteorological discrepancies. Consequently, specific projections of future climate change for 2021–2050 under three representative concentration pathway (RCP) scenarios (RCP2.6, RCP4.5, and RCP8.5) were completed for the HRB and ZRB, including daily precipitation, maximum air temperature, and minimum air temperature. The results demonstrated that the score-based method with multiple criteria for performance evaluation of multiple GCMs more accurately captured the spatio-temporal characteristics of the regional climate. The two statistical downscaling methods showed respective advantages in arid and humid regions. The statistical downscaling model (SDSM) showed more accurate prediction capacities for air temperature in the arid-climate HRB, whereas model output statistics (MOS) better captured the probability distribution of precipitation in the ZRB, which is characterized by a humid climate. According to the results obtained in this study, the selection of appropriate GCMs and downscaling methods for specific climate zones with different meteorological features significantly impact regional climate change projection. The statistical downscaling models developed and recommended for the north and south of China in this study provide scientific reference for sustainable water resource management subject to climate change.
Assessment of Causes and Effects of Groundwater Level Change in an Urban Area (Warsaw, Poland)
Authors: Krogulec Ewa , Małecki Jerzy J. , Porowska Dorota , Wojdalska Anna
Published: November 2020

Monitoring the data of groundwater level in long-term measurement series has allowed for assessment of the impact of natural and anthropogenic factors on groundwater recharge. It allows for assessing the actual groundwater quantity, which constitutes the basis for balanced and sustainable groundwater planning and management in an urban area. Groundwater levels in three aquifers were studied: the shallow and deeper Quaternary aquifers and the Oligocene aquifer in Warsaw (Poland). Statistical analysis was performed on a 27-year (1993–2019) cycle of daily measurements of groundwater levels. The studies focused on determining the range and causes of groundwater level changes in urban-area aquifers. The groundwater table position in the Quaternary aquifer pointed to variable long-term recharge and allowed for the identification of homogenous intervals with identification of water table fluctuation trends. A decrease in the water table was observed within the Quaternary aquifers. The Oligocene aquifer displayed an opposite trend.
A New Beach Topography-Based Method for Shoreline Identification
Authors: Luppichini Marco , Bini Monica , Paterni Marco , Berton Andrea , Merlino Silvia
Published: November 2020

The definition of shoreline is not the same for all contexts, and it is often a subjective matter. Various methods exist that are based on the use of different instruments that can determine and highlight a shoreline. In recent years, numerous studies have employed photogrammetric methods, based on different colours, to map the boundary between water and land. These works use images acquired by satellites, drones, or cameras, and differ mainly in terms of resolution. Such methods can identify a shoreline by means of automatic, semi-automatic, or manual procedures. The aim of this work is to find and promote a new and valid beach topography-based algorithm, able to identify the shoreline. We apply the Structure from Motion (SfM) techniques to reconstruct a high-resolution Digital Elevation Model by means of a drone for image acquisition. The algorithm is based on the variation of the topographic beach profile caused by the transition from water to sand. The SfM technique is not efficient when applied to reflecting surfaces like sea water resulting in a very irregular and unnatural profile over the sea. Taking advantage of this fact, the algorithm searches for the point in the space where a beach profile changes from irregular to regular, causing a transition from water to land. The algorithm is promoted by the release of a QGIS v3.x plugin, which allows the easy application and extraction of other shorelines.
“HOUSE LIKE A SHADOW”, “BUTTERFLY OF REVENGE” AND A “DEAD PORTRAIT”: MOTIF CONCORDANCE IN RUSSIAN GULAG POETRY AND CHINESE “FOG POETRY”
Authors: Boldyreva Elena M. , Asaf’yevа Elena V.
Published: November 2020

The article considers the system of creative concordances of Russian gulag poets and representatives of Chinese «fog poetry». The creative work of poets is analysed in the context of typologically similar trends in the Russian and Chinese literary process – the Russian literature of the gulag and the Chinese literature «wounds and scars», «the fate of poets are considered as an example of the complex opposition of the personality to the totalitarian system. When comparing the works of the «fog poets» and the poets of the gulag, a lot of motifs and figurative calls significant for the artistic world of poets are revealed: images of a butterfly of revenge, shadow, a portrait leading to horror, a motif for identifying historical memory, a motif for the absence of guilty, a destroyed youth, the inseparability of the fate of man from the fate of the homeland, a motif for suffering for the good and faith in the future, a representation of poetry as a way of survival and overcoming evil, a motif for resistance to nature, a steady and decisive movement forward, a motif for bodily destruction, voices from under stone, patience. After studying a number of common ideas and motifs, the authors of the article conclude that the creative work of «fog poets» and gulag poets is not only a way to survive in harsh conditions of imprisonment and exile, but also a historically significant phenomenon, because it reflects the nature of the era in which poets were forced to write and exist. This body of texts is considered as a material for studying the status of the poetry word as an aesthetic means capable of giving historical and artistic evidence of the Soviet and Chinese reality of the 20th century.
THE ACTIVITIES OF THE DONBASS CRIMINAL STAFF EMPLOYEES TO COMBAT CRIME ON RAILWAY TRANSPORT IN THE 1940S
Authors: Groshevaya Viktoriya K.
Published: November 2020

The article is devoted to the features of activity of criminal investigators of the Donbass for railway crime control in the 1940s. In the first years of the Soviet power there were no dramatic changes in railway crime development. However, in the years before World War II criminal activity in railway transport intensified significantly. Operational employees of the railway militia became to be responsible for the results of the fight against specific types of crimes, mainly against the most dangerous of them. In turn this required them to study in more depth the nature and dynamics of crime, as well as improve preventive and operational-search activities. Wherein special attention was paid to improving the quality of the intelligence work of the transport police and the timely removal of the criminal element penetrating the transport. Significant efforts were made in organising a system of counteraction to banditry, reflecting various aspects of the fight against organised crime. During the World War II in the Donbass territory the main task facing employees of the internal affairs bodies in transport
was to combat sabotage and attacks on trains and also other crimes related to inventory theft offences. At the same time, the tactics of the operational units of the criminal investigation department of the transport militia were formed and laid.
CAMPAIGN AGAINST THE OLD BELIEVERS’ RELIGION IN BURYATIA IN THE 1920S:
IMPLEMENTATION METHODS
Authors: Khomyakov Sergey V.
Published: November 2020

Purposeful struggle against religion became one of the most important directions in the ideology of the Soviet country in the 1920s. For Old Believers, who had been living in settlements along the Selenga River (near the City of Verkhneudinsk) since the 1760s, this meant a continuation of the conflict situation in communication and interaction with the contemporary government. The Old Believers, who for decades had been trying to preserve the specifics of the old Orthodox religion, fulfilled the entire list of economic and military duties, but resisted the decisions of the tsarist administration to eliminate the schism (sealing chapels, monitoring the activities of preceptors, conversion in coreligionism etc.). The Soviet power, established in the 1920s in Buryatia, demonstrated continuity in the perception of the Old Believer religion as a problem. Hence, the article sets a task of characterisation of the methods of the struggle of the Soviet government against the Old Believer religion in the 1920s. The goal of the research is an attempt to study the anti-religious campaign of the Bolsheviks in the settlements of the Old Believers of the Buryat-Mongol autonomous Soviet Socialist Republic, which can complete the ideas about their way of life, the attitude to the authorities in the turning point of the early Soviet power. The object of
the study is the Old Believers’ population of the Buryat-Mongol ASSR, the subject is the religious and cultural policy of the Soviet power. In the long-term planning of the Bolsheviks was the complete suppression of the religious worldview among the
population rather than elimination of the schism in the Orthodox Church (as before), hence the methods of achieving the goal were completely different – defamation of character of the preceptors, in many ways identical with the practices of working
with other religions, promotion ideas that religion is the main reason for their ignorance and lack of freedom, etc., among the Old Believer youth. In the 1920s (in contrast to the next decade of repressive politics) the authorities approached religion with caution, their methods were mainly aimed at creating a negative information background and supporting that part of the Old Believers who sought changes in their lives.

Published: November 2020

Introduction. Outbreaks of infectious diseases and the COVID-19 pandemic in particular pose a serious public health challenge.

The other side of the challenge is always opportunity, and today such opportunities are information technology, decision making systems, best practices of proactive management and control based on modern methods of data analysis (data driven decision making) and modeling.

The article reviews the prospects for the use of publicly available software in modeling epidemiological trends. Strengths and weaknesses, main characteristics and possible aspects of application are considered.

The purpose of the article is to review publicly available health software. Give situations in which one or another approach will be useful. Segment and determine the effectiveness of the underlying models. Note the prospects of high-performance computing to model the spread of epidemics.

Results. Although deterministic models are ready for practical use without specific additional settings, they lose comparing to other groups in terms of their functionality. To obtain evaluation results from stochastic and agentoriented models, you first need to specify the epidemic model, which requires deeper knowledge in the field of epidemiology, a good understanding of the statistical basis and the basic assumptions on which the model is based. Among the considered software, EMOD (Epidemiological MODelling software) from the Institute of Disease Modeling is a leader in functionality.

Conclusions. There is a free access to a relatively wide set of software, which was originally developed by antiepidemiological institutions for internal use in decision-making, however was later opened to the public. In general, these programs have been adapted to increase their practical application. Got narrowed focus on potential issues. The possibility of adaptive use was provided.

We can note the sufficient informativeness and convenience of using the software of the group of deterministic methods. Also, such models have a rather narrow functional focus. Stochastic models provide more functionality, but lose some of their ease of use. We have the maximum functionality from agentoriented models, although for their most effective use you need to have the appropriate skills to write program code.

Keywords: epidemiological software, deterministic modeling, stochastic modeling, agentoriented mode-ling, high performance computing, decision making systems.

Authors: Eissa Moataz , Mitarai Takuya , Amemiya Tomohiro , Miyamoto Yasuyuki , Nishiyama Nobuhiko
Published: November 2020

In this work, electron beam lithography proximity effect correction (PEC) was experimentally studied for patterning of Si photonic waveguides with a relatively thick resist mask. Beam’s energy density distribution (EDD) was experimentally extracted by the line exposure method; however, exposure lines in this work were developed after cleavage with a high-contrast process to reduce developer-related effects. The measured line spread function was fitted to a 4-Gaussian function to model mid-range energy densities accurately. The extracted EDD showed less proximity effects compared to conventional Monte-Carlo simulation performed by a commercial software. PEC processes with both techniques were experimentally compared for a Si photonic waveguide pattern with different side-cladding trench widths. Microscopic images confirmed that the presented calibration method could achieve better development conditions near the required clearance dosage. Single-mode propagation loss for a 500 × 220 nm Si wire waveguide was reduced from 3.2 to 2.4 dB cm−1 using the presented process.

Detection of Hepatitis B surface Antibodies (Anti-Hbs), Lifelong Immunity to HBV in HIV positive Patients in Ojo, Lagos, Nigeria
Authors: Anjorin Abdulazeez. A
Published: November 2020

Background: Detection of Hepatitis B surface antibodies (anti-HBs) in the serum implies that an individual is immune to HBV infection either from vaccination or past infection, which usually persists for life. Aim: This study was aimed to determine the seropositivity of anti-HBs among HIV-seropositive patients and further appraise the effect of co-infection on their immunological status in Ojo, Lagos. Materials and Methods: A total of 74 blood samples collected from HIV positive patients were analysed for anti-HBs (HBsAb) by Immunochromatographic assay (Biotec, UK). CD4+ count was determined using BD FACS Count Automated analyser. Results: Out of the 74 HIV infected patients screened, 12 (16.2 %) males and 62 (83.8 %) females, 2 patients (2.7 %) were positive for anti-HBs, with no prevalence among the males and 2.7 % among the females. Anti-HBs was only recorded in HIV positive patients in the 21-30 years age group (8.7 %). The result showed anti-HBs lifelong protection to HBV among HIV patients with CD4+ Count ranging from 601-700 and 901-1000 to be 1.7 % and 1.7 % respectively. Protection of 3.5 % was reported among antiretroviral therapy (ART) naïve patients and 0 % protection among ART patients. Conclusions: Our findings showed prevalence of 2.7% HBsAb in the studied HIV positive patients with a protection of 3.5 % anti-HBs to HBV among antiretroviral therapy (ART) naïve patients in Ojo, Lagos. The low prevalence of HBsAb in HIV positive patients may be attributed to suppression of immune responses leading to the loss of previously developed protective antibody against HBV infection. We hereby suggest anti-HBs screening for all HIV positive patients and that those negative should be vaccinated to help them develop protective immunity to HBV infection.
Assessment of Liquefaction Potential of Some Coastal Soils in Lagos, South-Western Nigeria Using Geophysical and Geotechnical Methods
Authors: Oladunjoye Hamid Titilope
Published: November 2020

Liquefaction occurs in shallow, loose, saturated deposits of cohesionless soils subjected to strong shearing stresses. This leads to the transfer of stress from the soil skeleton to the pore water precipitating a decrease in effective stress and shear resistance of the soil. The study gives the results of the liquefaction potential assessment in some part of Lagos wetland areas of Lagos. The aim of this study was to assess the liquefaction potential through the evaluation of its severity in response to Earth tremors. In order to achieve this purpose, Multi-channel Analysis of Surface waves (MASW) and Cone penetration testing (CPT) were carried out. For an optimal coverage of the study area, twenty-four channels 4.5Hz geophones connected to the ABEM Mark 6 Seismograph through two cable reels were used to detect the generated seismic wave produced by the weight drop of about 19.1 kg. The CPT soundings for assessing subsurface stratigraphy with respect to liquefiable soils were carried out with a 10-Ton Dutch Cone Penetrometer. The softwares used were SeisImager, for processing the MASW data and CLiq for the CPT measurements. The shear wave velocity models were generated for the MASW measurements. The models show that sand sediments with velocity ranging from 118 - 279 m/s dominated most of the study area. Also, the results show that for the potential liquefiable sands identified, the shear wave velocity ranges between 118.0 – 180 m/s delineated at depths between 10.0 – 20.0 m within study profile an is typical of liquefiable sands. Simplified procedure of assessment of Liquefaction potential from CPT showed a model curve whereby some CPT points were within the liquefiable zones.

An overview of the human immune system and the role of interferon regulatory factors (IRFs)
Authors: Kaur Ashwinder , Fang Chee-Mun
Published: November 2020

The immune system consists of a dynamic network of cells, proteins, tissues, and organs that communicate to provide adequate defense responses against pathogenic agents. The immune system divide into the non-specific (innate) and the specific (adaptive) components, where the interactions between these two arms are intricately regulated. To deploy effective immune responses, immune systems comprise various cells and molecules that communicate with each other via signaling pathways coordinated by gene regulatory networks. The interferon regulatory factors (IRFs) are critical regulators of both the immune system’s development and activation of different cells. To better understand the essential components of the normal immune system, this review essentially aims to cover the current knowledge of individual components of the immune system and the important role of IRFs in regulating the immune system.

The Ministry of Education Malaysia (MoE) has suggested usingFlipped Classroom (FC) teaching methodas an innovation inthe teaching of additional mathematics especially in algebra.The suggestion of using FC is very much related to the concept of 21th Century Classroom that emphasizes good communication, collaboration, critical as well as creative thinking. This quasi-experimentalresearchwas carried out to determine the effects of FC on the motivation of students taking additional mathematics.Treatment group (n = 36) was treated with FC methods, whereas control group (n = 34) received conventional methods of learning additional mathematics.To control the difference in dependent variables, a pre-test was given before the experiment started.After nine weeks of treatment, bothgroups were given a post-test.The motivational questionaire on additional mathematics was used as a tool to collect the data.In determining the differenceof databetweentreatment and control groups, thepre- andpost tests data were analyzed using multivariateanalysis ofvariance (MANOVA)followed by univariate analysis of variance(ANOVA).The findings from ANOVA analysis reveal that overall there was a difference between thetreatment and control groupsfor motivation.MANOVA analysis confirmsmore significant differences on motivational subscales namely on attention, relevance, level of confidence and satisfaction between these twogroups.In general, the impact was very substantial and gave a strong indication that the treatment was very meaningful.Therefore, this research has given a newandideal way of teaching additional mathematics to school administrators, subject teachers and students byengagingthe use ofalternativedynamic geometric softwares that are of the same quality as the ones supplied by MoE.

Kajian ini bertujuan bagi mendalami dan meneroka pengajaran matematik sekolah rendah menggunakan pendekatan kontekstual berdasarkan lapan komponen teori Johnson (2002). Terdapat tiga objektif kajian iaitu pemahaman guru matematik mengenai pendekatan kontekstual, pelaksanaan pengajaran kontekstual yang digunakan oleh guru matematik dan halangan yang dihadapi oleh guru matematik dalam proses pengajaran dan pembelajaran (PdPc). Reka bentuk kajian kes secara kualitatif dengan menggunakan penelitian kajian secara naturalistik telah dilaksanakan bagi mengamati sebuah latar tertentu tanpa sedikit pun mengubahnya di mana, persampelan adalah purposif. Kajian ini melibatkan 4 orang guru matematik daripada dua buah sekolah rendah daripada populasi 107 buah sekolah dalam Daerah Seremban, Negeri Sembilan. Kajian ini melibatkan empat kaedah pengumpulan data iaitu temu bual pra dan pasca- pengajaran, pemerhatian, nota lapangan (senarai semak) dan pengumpulan dokumen. Hasil kajian menunjukkan bahawa semua peserta kajian menghadapi kesukaran dan kurang pasti dalam menjelaskan makna pendekatan kontekstual, namun peserta kajian lebih berkeyakinan setelah menerima penerangan secara umum daripada penyelidik serta sebahagian besar peserta kajian berupaya melaksanakannya dalam proses PdP. Dapatan kajian juga menunjukkan peserta kedua dan ketiga berupaya melaksanakan pendekatan kontekstual dalam kedua-dua sesi, peserta keempat berupaya melaksanakannya pada sesi kedua berbanding sesi pertama, manakala peserta pertama tidak berupaya laksanakannya pada kedua-dua sesi pemerhatian pengajaran. Kesimpulan daripada kajian, penggunaan pendekatan kontekstual dalam pengajaran matematik sekolah rendah bergantung pada kefahaman dan pengetahuan guru tentang strategi pengajaran kontekstual secara mendalam dan berkesan. Implikasi kajian menunjukkan, pengajaran secara kontekstual menjadikan PdP guru bersama murid lebih bermakna dan efektif dengan mengaitkan Matematik dengan situasi sebenar dan kehidupan seharian.

Kajian ini bertujuan untuk menentukan dan mengatasi masalah yang dihadapi oleh pelajar di dalam topik operasi penambahan dan penolakan pecahan. Tinjauan awal dilakukan melalui semakan latihan dan ujian pra mendapati pelajar mempunyai masalah terhadap topik berkenaan. Hasil tinjauan tersebut seramai 10 orang pelajar telah dijadikan sampel kajian. Ia melibatkan pelajar tahun 4 di salah sebuah sekolah sekitar Wilayah Persekutuan Kuala Lumpur. Pembinaan Fraction Cipher dilakukan sebagai bahan bantu mengajar bagi mengatasi masalah tersebut. Tiga instrumen utama digunakan dalam kajian ini seperti ujian pencapaian matematik (pecahan), instrumen pemerhatian dan instrumen temu bual separa struktur. Kajian dimulakan dengan ujian pra, intervensi selama empat minggu, ujian pos dan temubual pelajar seminggu selepas ujian pos dijalankan. Hasil kajian ini diharapkan dapat memberikan gambaran jelas kemampuan Fraction Cipher sebagai bahan bantu pengajaran alternatif yang dapat dilaksanakan oleh guru dan pendidik dalam mengamalkan pengajaran dan pembelajaran untuk abad ke-21. Kajian ini juga diharapkan dapat membantu Aspirasi dan Misi Negara Malaysia dalam membangunkan modal insan yang berjaya.

Dual Language Programme (DLP) was introduced to improve the level of English proficiency among students. This has become a hot topic since the Ministry of Education (MOE) was requested to review the implementation of DLP as the teachers and students face challenges in teaching and learning of Science and Mathematics in English. Thus, this study aims to identify the teachers’ and students’ insights on DLP and the challenges they faced after the implementation. The data were obtained through a questionnaire. A total of 146 DLP students consisting of Form 1 and Form 2 students and 8 teachers from four secondary schools in Klang, Selangor participated in this study. Besides, semi-structured interviews were carried out among the teachers as well. The finding shows that most of the teachers and students have positive views towards the implementation of DLP, although they faced some challenges. Moreover, students are keen to learn Science and Mathematics in English even though their English proficiency still at the unsatisfying level.

Currently, COVID-19 is unquestionably becoming a universal problem and for the predictable forthcoming. It has aroused an alarm concerning the spread and infects humans worldwide. In COVID-19, Olfactory and taste disorders (OTDs) are newly testified disorders and have been hypothesized that oral and nasal tissues possibly encompass host cells of SARS-CoV-2. Researchers have concluded that hyposmia or anosmia (decrease or loss of smell) and ageusia (loss of taste) is a key indicator that a person who else gives the impression that he is healthy is carrying the virus and possibly be spreading it to others. Hereby, this article gives an insight review of these indicators.

Legumes are the plant that contains high protein content that has been used as supplementary for animal feed and has a great potential to increase the productivity of livestock. However, no much study has been measured on the nutritive value of legume species. Thus, the aims of this study were to measure the nutritive content in the leaves of three different legume species (Leucaena leucocephala, Calopogonium mucunoides and Stylosanthes guianensis) and to compare the species that contain high of nutritive value. The samples were collected in Tembila area, Besut, Terengganu, then were brought to the Plant Physiology laboratory at UniSZA Kampus Besut for sample preparation. The samples were washed under tap water for 30 seconds to prevent nutrient leaching, then were dried and ground before analyzed by proximate analysis and mineral analysis using Induces Coupled Plasma Optical Emission Spectrometry (ICP-OES) machine. The parameters that were measured by using the proximate analysis consist of dry matter (DM), crude protein (CP), crude fibre (CF), ash, ether extract (EE) and Nitrogen Free Extract (NFE). For mineral analysis, the samples were analyzed for Calcium (Ca), Zinc (Zn), Iron (Fe), Copper (Cu) and Manganese (Mn). The results of this study showed that Leucaena leucocephala had significantly higher (p < 0.05) of CP and EE. While, Stylosanthes guianensis had significantly higher (p < 0.05) of the micro-elements which are Zn, Fe and Mn. Therefore, this study revealed that L. leucocephala contained the highest nutritive value of CP, EE and Calcium.
