Introduction: Breast cancer is the most commonly happening female cancer and the leading cause of cancer deaths worldwide. Breast cancer is a heterogeneous disease and it encompasses a variety of entities with distinct morphological appearances and clinical behaviors. Triple-negative breast cancer (TNBC) represents 12.5– 15% of all breast cancers. Its molecular dissimilarity also brings a significantly different clinical course. It has been observed that basal-like breast cancers exhibit a gene expression profile very similar to that of myoepithelial cells. Aim of the study: To identify the basal like TNBC cases and correlate them with histomorphological grade. Material & Methods: This cross sectional study was conducted in the department of BSMMU from January 2016 to December 2017. A total of 41 cases previously diagnosed as TNBC by histological and immunohistochemical examinations were selected for the study. During collecting specimen, all relevant information were recorded systemically in a prescribed proforma. Histopathogical type of tumor was done according to WHO classification of breast tumor, 2012 and grading was done followings Nottingham modification of the Bloom -Richardson Grading System, and recorded. Immunohistochemistry of ER, PR and HER-2/neu expression of all cases were performed using Dako Autostainer Plus at the immunohistochemistry laboratory, of department of Pathology, BSMMU. Statistical analyses of the results were obtained by window based computer software devised with Statistical Packages for Social Sciences (SPSS-20). Prior to the commencement of this study the thesis protocol was submitted to the Institutional Review Board (IRB) of BSMMU, Dhaka for approval and was approved. Results: A total number of 41 cases were selected for the study out of these 41 cases; most of the cases belong to a range of 31 to 40 years. Minimum age was 26 years, maximum age was 70 years. The mean age was 42. There is no association between age and CK 5/6 ......

Published: February 2022

Rapid population growth has had a significant effect on increasing food demand. However, the conversion of agricultural land to non-agricultural land cannot be avoided. Currently, there are only 8.1 million hectares of agricultural land and it is estimated that this will decrease to 5.1 million hectares of agricultural land by 2045. Hydroponic agriculture is one of the solutions for efficient use of agricultural land, one of which is the Hydroponic Nutrient Film Technique. That must be maintained and controlled are pH, Electrical Conductivity (EC), and flow. The optimum value of each parameter is pH 6, EC 5mS cm-1, and a flow of 1.5 l / m. However, the optimal value of each parameter will change with changing conditions and environment. As an innovative solution, the authors offer SANIC technology, a smart agricultural control system in NFT hydroponic based on artificial intelligence of things. The methodology used in this paper is ADDIE (Analysis, Design, Development, Implementation, and Evaluate). This technology has a multifunctional plant treatment that works automatically. The equipment is integrated with several components such as a pH sensor, Solenoid Valve, Flow Sensor and EC meter. The main system of this technology is controlled intelligently by Fuzzy Logic rules. This technology is also equipped with solar panels to support environmentally friendly energy needs.

Authors: Wahyudi Lalu Iman Novian , Antariksa Antariksa , Parlindungan Johanes
Published: February 2022

The Rembitan village is one of the villages in Pujut Subdistrict that still maintains the traditional traditions and culture of the Sasak Tribe. This tradition has built a system of life for the Sasak people who are believed to bring good for themselves and the group. This tribe is a good community and that has been oriented to Ancient Mosque Rembitan which builds the existing traditions and culture. At this time the tradition of this tradition began to decrease in demand and the understanding of its successors related to polishing culture began to decrease due to cultural acculturation. For this reason, there needs to be a continuity of cultural knowledge for the next generation to ensure the preservation of the culture and uniqueness of the region. The purpose of this research is to describe the value contained in polishing culture so that the next generation can learn and understand the meaning and purpose of each tradition carried out by its predecessors. This study shows that the role of the Ancient Mosque of Rembitan is very visible and orientates every activity in Rembitan Village. This is manifested in the form of beliefs, attitudes, and visible symbols such as settlements and indigenous polishing activities. The results of the analysis showed that the role of the Ancient Rembitan mosque was as a space or container for the people of Rembitan Village in carrying out every process of life, both in the form of physical and cultural activities (polishing).
Evaluating Financial Integration and Cooperation in the ASEAN
Authors: Harvey Brendan
Published: February 2022

Financial integration is less pronounced in the ASEAN than other measures of economic integration. This is particularly apparent when compared against other regions that have undergone similar integrative efforts, such as the European Union. Cross-border trade flows, foreign-direct investment, and investment in capital goods outstrip other investment flows. Regional institutional and legal structures governing these investment flows, while limited, present marked achievements towards creating an ASEAN financial community. The gap persists despite suggestions that the Asian Financial Crisis and the Global Financial Crisis (or the North Atlantic Financial Crisis from the Asian and Stiglitz perspective) would accelerate financial regionalism as a way to create a wider safety net against sudden capital outflow or capital stoppage. This paper will endeavor to offer legal, governance, and institutional explanations to explain the impetus for the ASEAN to integrate within itself instead of the Western financial system. It will offer suggestions to augment financial integration by making changes to the most effective initiatives.

Published: February 2022

The goal of this study was to see if language learning beliefs had a mediation influence on students language anxiety in relation to teaching style. In this case, a descriptive correlational survey was used as part of a quantitative research project. It was conducted with 332 research participants at a private institution in Digos City. Adapted questionnaires from Grasha’s Teaching Styles Inventory (2002), Horwitz’s (1987) Beliefs About Language Learning Inventory (BALLI), and Foreign Language Classroom Anxiety were the three instruments used in this study. Horwitz, Horwitz, and Cope are the three levels of the FLCAS scale (1986). The Google survey form was utilized to facilitate the investigation. In the data analysis, the mean, regression analysis, Pearson r, and the Sobel z-test were used. As a result of this research, it has been determined that there is a very high level in each teaching style. Moderate level of anxiety in the Filipino language and high level of belief in language learning. In addition, the variables in this study show a significant correlation. Thus, as a result of the significant correlation of each variable, it was found that there was a full mediation of the effect on language learning beliefs in the correlation of teaching styles and students’ language anxiety.

Analisis Performa Segment Routing dan Reactive Routing pada Software-defined Networking
Authors: Fuadi Lutfi Kiki
Published: February 2022

Software-defined Networking (SDN) is a new paradigm in computer network management that separates the control plane and data plane. The controller is an important component in an SDN-based computer network. The purpose of this research is to conduct a comparative study of the performance of segment routing and reactive routing in SDN. In this study, ONOS was chosen as the controller used in the experiment because it supports the implementation of segment routing and reactive routing. The experiment of implementing the two routing protocols on an SDN network with a full-mesh and tree (depth 5) network topology is the scenario that is tried in this study. QoS results based on TIPHON parameters (throughput, packet loss, delay and jitter) were recorded from each experiment. The throughput of each experiment was 6.97 MB/s, 5.80 MB/s, 1.65 ms and 2.16 ms, indicating index 4 (very good). Packet loss in the full-mesh topology experiment was 5.16% and 5.53% with index 3 (good), while in tree (depth 5) the results were 2.46% and 2.16% showed index 4 (very good). The delay for each experiment was 2.99 ms, 3.17 ms, 4.65 ms and 5.43 ms, indicating an index of 4 (very good). The jitter for each experiment was 7.10 ms, 7.85 ms, 18.30 ms and 18.13 ms, indicating index 3 (good).
Subgraph Complementation and Minimum Rank
Authors: Buchanan Calum , Purcell Christopher , Rombach Puck
Published: February 2022

Any finite simple graph $G = (V,E)$ can be represented by a collection $\mathscr{C}$ of subsets of $V$ such that $uv\in E$ if and only if $u$ and $v$ appear together in an odd number of sets in $\mathscr{C}$. Let $c_2(G)$ denote the minimum cardinality of such a collection. This invariant is equivalent to the minimum dimension of a faithful orthogonal representation of $G$ over $\mathbb{F}_2$ and is closely connected to the minimum rank of $G$. We show that $c_2 (G) = \operatorname{mr}(G,\mathbb{F}_2)$ when $\operatorname{mr}(G,\mathbb{F}_2)$ is odd, or when $G$ is a forest. Otherwise, $\operatorname{mr}(G,\mathbb{F}_2)\leqslant c_2 (G)\leqslant \operatorname{mr}(G,\mathbb{F}_2)+1$. Furthermore, we show that the following are equivalent for any graph $G$ with at least one edge: i. $c_2(G)=\operatorname{mr}(G,\mathbb{F}_2)+1$; ii. the adjacency matrix of $G$ is the unique matrix of rank $\operatorname{mr}(G,\mathbb{F}_2)$ which fits $G$ over $\mathbb{F}_2$; iii. there is a minimum collection $\mathscr{C}$ as described in which every vertex appears an even number of times; and iv. for every component $G'$ of $G$, $c_2(G') = \operatorname{mr}(G',\mathbb{F}_2) + 1$. We also show that, for these graphs, $\operatorname{mr}(G,\mathbb{F}_2)$ is twice the minimum number of tricliques whose symmetric difference of edge sets is $E$. Additionally, we provide a set of upper bounds on $c_2(G)$ in terms of the order, size, and vertex cover number of $G$. Finally, we show that the class of graphs with $c_2(G)\leqslant k$ is hereditary and finitely defined. For odd $k$, the sets of minimal forbidden induced subgraphs are the same as those for the property $\operatorname{mr}(G,\mathbb{F}_2)\leq k$, and we exhibit this set for $c_2(G) \leqslant 2$.
The Density of Fan-Planar Graphs
Authors: Kaufmann Michael , Ueckerdt Torsten
Published: February 2022

A topological drawing of a graph is fan-planar if for each edge $e$ the edges crossing $e$ form a star and no endpoint of $e$ is enclosed by $e$ and its crossing edges. A fan-planar graph is a graph admitting such a drawing. Equivalently, this can be formulated by three forbidden patterns, one of which is the configuration where $e$ is crossed by two independent edges and the other two where $e$ is crossed by two incident edges in a way that encloses some endpoint of $e$. A topological drawing is simple if any two edges have at most one point in common.

 Fan-planar graphs are a new member in the ever-growing list of topological graphs defined by forbidden intersection patterns, such as planar graphs and their generalizations, Turán-graphs and Conway's thrackle conjecture. Hence fan-planar graphs fall into an important field in combinatorial geometry with applications in various areas of discrete mathematics.

 As every $1$-planar graph is fan-planar and every fan-planar graph is $3$-quasiplanar, they also fit perfectly in a recent series of works on nearly-planar graphs from the areas of graph drawing and combinatorial embeddings.

In this paper we show that every fan-planar graph on $n$ vertices has at most $5n-10$ edges, even though a fan-planar drawing may have a quadratic number of crossings. Our bound, which is tight for every $n \geq 20$, indicates how nicely fan-planar graphs fit in the row with planar graphs ($3n-6$ edges) and $1$-planar graphs ($4n-8$ edges). With this, fan-planar graphs form an inclusion-wise largest non-trivial class of topological graphs defined by forbidden patterns, for which the maximum number of edges on $n$ vertices is known exactly.

We demonstrate that maximum fan-planar graphs carry a rich structure, which makes this class attractive for many algorithms commonly used in graph drawing. Finally, we discuss possible extensions and generalizations of these new concepts.
Bohr Neighborhoods in Generalized Difference Sets
Authors: Griesmer John T.
Published: February 2022

If $A$ is a set of integers having positive upper Banach density and $r,s,t$ are nonzero integers whose sum is zero, a theorem of Bergelson and Ruzsa says that the set $rA+sA+tA:=\{ra_1+sa_2+ta_3:a_i\in A\}$ contains a Bohr neighborhood of zero.  We prove a natural generalization of this result for subsets of countable abelian groups and more summands.

Trichloroacetic acid fueled practical amine purifications
Authors: Thomas Aleena , Gasch Baptiste , Olivieri Enzo , Quintard Adrien
Published: February 2022

Amine purification have for long been dominated by tedious stepwise processes involving the generation of large amounts of undesired waste. Inspired by recent work on out of equilibrium molecular machinery, using trichloroacetic acid (TCA), we disclose a purification technique considerably decreasing the number of operations and the waste generation required for such purifications. At first, TCA triggers the precipitation of the amines through their protonated salt formation, enabling the separation with the impurities. From these amine salts, simple decarboxylation of TCA liberates volatile CO2 and chloroform affording directly the pure amines. Through this approach, a broad range of diversely substituted amines could be isolated with success.

We present the third and final data release of the K2 Galactic Archaeology Program (K2 GAP) for Campaigns C1–C8 and C10–C18. We provide asteroseismic radius and mass coefficients, κ

R
and κ

M
, for ∼19,000 red giant stars, which translate directly to radius and mass given a temperature. As such, K2 GAP DR3 represents the largest asteroseismic sample in the literature to date. K2 GAP DR3 stellar parameters are calibrated to be on an absolute parallactic scale based on Gaia DR2, with red giant branch and red clump evolutionary state classifications provided via a machine-learning approach. Combining these stellar parameters with GALAH DR3 spectroscopy, we determine asteroseismic ages with precisions of ∼20%–30% and compare age-abundance relations to Galactic chemical evolution models among both low- and high-α populations for α, light, iron-peak, and neutron-capture elements. We confirm recent indications in the literature of both increased Ba production at late Galactic times as well as significant contributions to r-process enrichment from prompt sources associated with, e.g., core-collapse supernovae. With an eye toward other Galactic archeology applications, we characterize K2 GAP DR3 uncertainties and completeness using injection tests, suggesting that K2 GAP DR3 is largely unbiased in mass/age, with uncertainties of 2.9% (stat.) ± 0.1% (syst.) and 6.7% (stat.) ± 0.3% (syst.) in κ

R
and κ

M
for red giant branch stars and 4.7% (stat.) ± 0.3% (syst.) and 11% (stat.) ± 0.9% (syst.) for red clump stars. We also identify percent-level asteroseismic systematics, which are likely related to the time baseline of the underlying data, and which therefore should be considered in TESS asteroseismic analysis.
Electron Rolling-pin Distribution Inside Magnetic Hole
Authors: Yu Y. , Fu H. S. , Cao J. B. , Liu Y. Y. , Wang Z.
Published: February 2022

Magnetic holes (MHs), characterized by depressions in the magnetic field magnitude, are transient magnetic structures ubiquitous in space plasmas. The electron pitch-angle distribution inside the MHs is key to diagnosing the MH properties and has been suggested to mainly exhibit a pancake-type distribution showing pitch angles near 90°. Here, we present the first observation of electron rolling-pin distribution—showing electron pitch angles mainly at 0°, 90°, and 180°—within an electron-scale MH, by using Magnetospheric Multiscale mission high-resolution measurements. With a second-order Taylor expansion method, the magnetic field topology of the MH is reconstructed, and the characteristics of the rolling-pin distribution inside the MH are investigated. We find that the rolling-pin distribution primarily appears near the MH center and at energies ranging from 110 to 1200 eV. We interpret the rolling-pin formation as a consequence of the combination of local-scale electron trapping and global-scale Fermi acceleration. These results can improve current understanding of electron dynamics in the MHs.
Dust Extinction Law in Nearby Star-resolved Galaxies. I. M31 Traced by Supergiants
Authors: Wang 王 Yuxi 钰溪 , Gao 高 Jian 健 , Ren 任 Yi 逸
Published: February 2022

The dust extinction laws and dust properties in M31 are explored with a sample of reddened O-type and B-type supergiants obtained from the Local Group Galaxies Survey (LGGS). The observed spectral energy distributions (SEDs) for each tracer are constructed with multiband photometry from the LGGS, PS1 Survey, UKIRT, PHAT Survey, Swift/UVOT, and XMM-SUSS. We model the SED for each tracer in combination with the intrinsic spectrum obtained from the stellar model atmosphere extinguished by the model extinction curves. Instead of mathematically parameterizing the extinction functions, the model extinction curves in this work are directly derived from the silicate–graphite dust model with a dust size distribution of

Au rythme des spécialisations : travail et exploitations agricoles dans le Vaucluse (1945-1958)
Authors: Mignemi Niccolò
Published: February 2022

Cet article explore l’essor des spécialisations fruitières et maraîchères sous l’angle de la mobilisation de la main-d’œuvre. Il se focalise sur le cas du Vaucluse entre 1945 et la fin des années 1950. Les données du premier recensement des exploitations servent de point de départ pour réinterroger les binômes traditionnels (familial/salarié, permanent/saisonnier, local/étranger) identifiables dans l’organisation du travail agricole. La production de fruits et légumes repose, en effet, sur la capacité de concilier deux exigences. D’une part, ces cultures s’appuient sur une mobilisation intensive de la main-d’œuvre s’étalant le plus possible sur l’année. D’autre part, elles nécessitent un système d’emploi fluide capable de fournir régulièrement une réponse aussi ponctuelle que rapide afin de préserver la qualité et la rentabilité des récoltes, face aux aléas du climat et des marchés. Si la famille se confirme comme la source première de bras occupés à temps plein ou de manière temporaire, la documentation de la Commission paritaire départementale de travail agricole permet d’approfondir le rôle crucial du salariat. Les débats sur la diversité des statuts et des systèmes de rémunération deviennent alors l’occasion pour explorer les clivages de genre, d’âge et de qualification observables chez les ouvriers et les ouvrières agricoles, ainsi que les nouvelles tensions déterminées par l’accélération de l’exode rural et professionnel.

Les réseaux personnels en France ont-ils changé ? Une comparaison entre 2001 et 2017
Authors: Favre Guillaume , Grossetti Michel
Published: February 2022

La réplique en 2017 d’une partie d’une enquête réalisée en 2001 permet d’étudier l’évolution des réseaux de relations interpersonnelles en France sur une durée de seize ans. Les résultats sont convergents avec ceux d’études comparables effectuées dans d’autres pays, et en particulier aux États-Unis. Alors que, dans les années 2000, divers auteurs pronostiquaient des évolutions majeures des réseaux personnels, ceux-ci se révèlent remarquablement stables dans leur composition comme dans leur structure. On n’observe ni une réduction de leur taille ni des changements massifs dans leur composition (part des relations familiales, professionnelles, de voisinage, etc.). On note néanmoins des changements parallèles à certaines évolutions de la société française (élévation des niveaux d’études, augmentation de l’âge au premier enfant, périurbanisation, etc.) : une évolution des contextes de création des relations pour les 18-30 ans et les plus de 60 ans, une croissance de l’entre-soi des catégories sociales les plus diplômées, et une diminution de la densité des réseaux dans les espaces ruraux.
Exact travelling solution for a reaction-diffusion system with a piecewise constant production supported by a codimension-1 subspace
Authors: Zadorin Anton S.
Published: February 2022

A generalisation of reaction diffusion systems and their travelling solutions to cases when the productive part of the reaction happens only on a surface in space or on a line on plane but the degradation and the diffusion happen in bulk are important for modelling various biological processes. These include problems of invasive species propagation along boundaries of ecozones, problems of gene spread in such situations, morphogenesis in cavities, intracellular reaction etc. Piecewise linear approximations of reaction terms in reaction-diffusion systems often result in exact solutions of propagation front problems. This article presents an exact travelling solution for a reaction-diffusion system with a piecewise constant production restricted to a codimension-1 subset. The solution is monotone, propagates with the unique constant velocity, and connects the trivial solution to a nontrivial nonhomogeneous stationary solution of the problem. The properties of the solution closely parallel the properties of monotone travelling solutions in classical bistable reaction-diffusion systems.
Decision Framework for Cross-Platform Mobile Development Frameworks Using an Integrated Multi-Criteria Decision-Making Methodology
Authors: Lachgar Mohamed , Hanine Mohamed , Benouda Hanane , Ommane Younes
Published: February 2022

Because of the growing popularity of smartphones and tablets, the use of mobile applications has exploded recently. However, the variety of mobile platforms compels developers to create an app for each, making the process more complex and expensive. Thus, open-source cross-platform mobile frameworks have been developed to address this problem, allowing the same code to be imported across various operating systems. This paper comes to propose a new framework for the selection of the appropriate platform for the implementation of a cross-platform mobile application. This framework is based on the most used multi-criteria decision-making (MCDM) methods, namely analytic hierarchy process (AHP) and technique for order preference by similarity to ideal solution (TOPSIS) methods are used. A demonstrative example is proposed to illustrate the suggested methodology.
High-Efficiency Multihomed Multimedia Transmission in Wireless Sensors
Authors: Wang Haitao , Chen Yanli
Published: February 2022

For real-time video transmission in multimedia sensor networks, efficient and reliable communication is very important. However, under actual conditions, when the sensor transmits data to the sink node, the link between the sensor and the sink node usually becomes unstable due to bandwidth limitations and unstable transmission links. Unstable data transmission will affect the normal data transmission of sensor nodes, and even cause sensor nodes to fail to communicate with sink nodes. These problems make users who use multimedia sensor networks have a poor user experience. In order to solve these problems, a brand-new multi-homed multi-connection system was designed for wireless multimedia sensors, and a prototype system was implemented. Compared with the traditional single-homed connection mode, the system can maintain a more stable connection under the same bandwidth, memory and CPU resource constraints.
Mobile Location-Based Services
Authors: Baek Heon
Published: February 2022

This study investigated three factors of self-determination theory (SDT) that influence the intrinsic and external motivation of mobile location-based services (M-LBS). This study was conducted on M-LBS users through an online survey, and a total of 308 response data were used for analysis The results showed that the three factors of SDT significantly influenced the extrinsic motivation of M-LBS and only perceived relatedness significantly affected intrinsic motivation. Intrinsic and external motivation had a great influence on attitudes and attitudes. Recognized competency influenced perceived usefulness more than pull type. A positive attitude influenced the intention to continue pulling rather than pushing. According to service type (i.e., push and pull), users are more likely to continue to use the service when users are satisfied with the service requested by M-LBS than when the operator provides the service on its own, so they need to understand how M-LBS affects perceived usefulness and intrinsic motivation.
Optimization of the Steady Combined Forward and Backward Extrusion Test for Higher Sensitivity to Friction in Cold Forging
Authors: Hu Cheng Liang , Osaki Shogo , Cai Bai Xuan , Aoyama Mitsuru
Published: February 2022

To improve the sensitivity of the steady combined forward and backward extrusion test proposed in previous work, an optimization job based on the finite element simulations was carried out. A raw material of 0.45% carbon steel was tested under different stain rates from 0.001s-1 to 1s-1 and different temperatures from 30°C to 400°C, and the material flow stresses were modelled by Hensel-Spittel equation. The deformation degree of the forward extrusion was set as 50%. The key parameters including the deformation degree of the backward extrusion, the ratio between the radius of the punch nose and the radius of the punch, the taper angle of the punch, the die angle, the sizing lands of the punch and the die were optimized. The sensitivity of the optimal design is improved about 20% compared with previous design when the friction factor is assumed as 0.03~0.15. The new group of calibration curves presents more scatter than the old group. The sensitivity improvement is also validated by the experimental works.

Published: February 2022

Polarisation methods, and Open circuit potential measurements have been utilized to evaluate the impact of heat remediation on the corrosion characteristics of CuAlNi shape memory alloy in 3.5 percent NaCl solutions. CuAlNi alloy specimens were investigated in their as-sintered condition and following a thermal remediation processing that included annealing at 900 °C for 60 min associated with water quenching, and 200-degree centigrade for 30 hrs. and rapid cooling in iced water. The enhancement in polarisation resistance and reduction in corrosion rate of heat-treated CuAlNi alloy further suggests that heat remediation has a positive effect on CuAlNi alloy corrosion resistance. After measurements of polarisation, optical microscopy, SEM/EDX, and XRD examination of specimen surfaces reveal the presence of corrosion damage on the electrode surfaces, with CuCl2, AlCl3, and Cu2Cl (OH)3 compounds as surface corrosion products..

In this study, new tetrazole [A1-A5] were prepared by the reaction of Schiff base with sodium azide in tetrahydrofuran (THF) by the traditional method (reflux) and microwave technology. The prepared compounds were characterized by physical properties, UV-Vis, FT-IR,1H-NMR,13C-NMR spectral, and C.H.N analysis. TLC checked the purity of these compounds. Antibacterial behaviors were investigated against a variety of bacteria, includingEscherichia coli,andKlebsiella pneumoniaGram (-) ve,Staphylococcus aureus, andStaphylococcus epidermidisGram (+) ve. The laser efficacy of the [A1-A5] was evaluated after they were radiated by laser for (10, 20, 30) seconds. As the melting point, and color of the substances were determined, it was discovered that they were unaffected, and did not disintegrate or polymerize. Using the Chem3D 19.0 program, the heat of the formulation of the [A1-A5] was investigated.

Prosthetic socket is the device that link artificial limb with the amputee part. This work has been done on seven laminated composite were prepared by vacuum technique from Polyester resin reinforced with (Jute, Carbon, Glass, Perlon) fibers. The interaction between fibers and matrix material was studied using Fourier transform infrared (FTIR) spectroscopy. DSC test also had been studied for different laminated composite materials to make prosthetic socket. The infrared spectra result of the Polyester composite specimens with natural and synthetic fibers indicate that no additional new peak was observed. While DSC results showed the increase in the glass transition temperature (Tg) as the number of Jute layers increased and this may be related to the nature of Jute fibers. As well as Carbon lead to increase Tg but Glass fiber decreased Tg when added to natural fiber (Jute fiber). The composite specimen reinforced with three layers of Jute fibers plus four layers of Carbon fibers (3 Jute + 4 Carbon) had the highest Tg (107°C).

In this study, pristine graphene/silver/molybdenum disulphide (G/Ag/MoS2) and reduced graphene oxide/silver/molybdenum disulphide (rGO/Ag/MoS2) composites materials were prepared via green solvothermal synthesis method and evaluated as supercapacitor electrodes. The morphology and structure of composites were examined by using Scanning Electron Microscopy (SEM), Energy dispersive spectroscopy (EDX), X-ray diffraction spectroscopy (XRD), and Raman spectroscopy. SEM and TEM indicate successful reduction of silver nitrate (AgNO3) to spherical Ag nanoparticles (NPs) by sodium citrate. The Ag NPs were observed to be evenly deposited on sheets of rGO and MoS2. From the XPS analysis, the spherical Ag NPs exist in zero-valent state, reflecting successful reduction. Based on cyclic voltammetry (CV) performed under 50 mV/s scan rate, G/Ag/MoS2 ternary composite exhibits the highest specific capacitance of 56.38 F/g which is 31 % and 29 % enhancement in specific capacitance of rGO/Ag/MoS2 ternary composite and Ag/MoS2 binary composite, respectively. It is believed that the presence of graphene may provide conductive pathway and a larger surface area for the distribution of Ag NPs.
Making Sure that Health Messaging is Effectively Communicated: A Fundamental Obligation for Pharmacists
Authors: Alderman Chris
Published: February 2022

Though communication problems in everyday life which arise from language difficulties or other issues can interfere with effective verbal and written communication, the potential problems extend far beyond amenity of life. In no realm is this more apparent than in the context of health care, where the types of barriers discussed not only create difficulty in accessing the health care system, but also problems in negotiating it safely. When paired with socio-economic disadvantage that often accompanies the situation of living in a society where an person does not speak the prevailing language, the difficulties rapidly compound.

The fall armyworm (FAW) Spodoptera frugiperda (J.E. Smith), an invasive pest of cereal crops in Africa, poses a real threat to food security in sub-Saharan African countries where cereals are the staple food. Since its appearance in Africa in 2016, the FAW has invaded almost all African countries due to its great dispersal capacity. Because of its resistance to a number of chemical pesticides but also the risks associated with the use of these, the search for an alternative method becomes essential. In order to report on the incidence of this pest and explore its associations with native natural enemies, a monitoring study of S. frugiperda populations, its damage as well as its natural enemies was carried out during the period of August to September 2020 in corn fields of two agro-ecological zones of Senegal and in the laboratory. Monitoring results show a heavy infestation with rates of up to nearly 75% of defoliated plants and more than 60% of attacked ears. The damage recorded remains low overall (score below 3/9). A wide range of auxiliary insects (17 families) made up of parasitoids and predators were identified in the field and in the laboratory as well as an endoparasitic nematode with a parasitism rate of 38.46% and a fungus in one of the sites. These results pave the way for the development of an approach to control CLA with these biological agents.

La carence en vitamine A constitue un problème de santé publique dans les pays en développement et affecte en particulier les jeunes enfants et les femmes en âge de procréer. Le but de cette étude était d'évaluer l’application de la politique nationale en matière de production et d’importation, des huiles végétales raffinées, d’enrichissement obligatoire en vitamine A au Burkina Faso, à travers la détermination de la teneur en vitamine A et de l'indice de peroxyde des huiles végétales vendues sur le marché. Cette étude transversale a été menée dans cinq villes sélectionnées selon la densité de la population. Cinquante-neuf échantillons d’huile ont été achetés dans ces villes pour évaluer la teneur en vitamine A, l'indice de peroxyde et leur conformité aux normes nationales et internationales. Dans l'ensemble, 76,27% des huiles n'étaient pas suffisamment enrichies en vitamine A. Pour l'indice de peroxyde, 3,39% des huiles n'étaient pas conformes. Globalement, 77,97% des huiles n'étaient pas conformes pour ces deux paramètres. Au regard de ces résultats il est nécessaire d’intensifier la lutte contre la mise à la consommation des huiles non enrichies en vitamine A au Burkina Faso.

English title: valuation of the vitamin A content and the peroxide value of vegetable oils commonly sold in markets in Burkina Faso

Vitamin A deficiency is a public health problem in developing countries and particularly affects young children and women of childbearing age. The aim of this study was to assess the implementation of the national policy on the production and importation of refined vegetable oils and mandatory vitamin A fortification in Burkina Faso, through the determination of the vitamin A content and peroxide value of vegetable oils sold on the market. A cross-sectional study was conducted in five cities selected according to population density. Fifty-nine oil samples were purchased in these cities to assess vitamin A content, peroxide value and compliance with national and Codex standards. Overall, 76.17% of the oils were not adequately fortified with vitamin A. For the peroxide value, 3.39% of the oils did not comply. Overall, 77.97% of the oils did not comply for these two parameters. In view of these results, it is necessary to intensify the fight against the consumption of oils not enriched in vitamin A in Burkina Faso.

Les systèmes agroforestiers contribuent comme les forêts à la conservation physique et chimique du sol, à la régulation thermique et à la conservation de la biodiversité. Cette étude visait à caractériser la communauté des espèces ligneuses alimentaires dans quatre systèmes agroforestiers périphériques au noyau central de la Forêt Classée de la Lama. Au total, 770 placeaux carrés (30 m x 30 m) ont été installés de façon aléatoire dans les champs, plantations privées, jardins de case et jachères. Dans chaque placeau, des mesures dendrométriques (diamètre) ont été effectuées sur les individus de diamètre ≥ 5 cm à 1,30 m du sol. L’indice de similarité de Jaccard et le diagramme de Venn ont permis d’évaluer la similarité entre les systèmes agroforestiers. La valeur la plus élevée de l’indice de Shannon a été enregistrée dans les jachères. La structure en diamètre des ligneux présentait une prédominance des sujets de petit diamètre [5-25 cm [. Les jardins de case étaient les seuls regroupant des individus de petites tailles. Une faible variation floristique a été observée entre les systèmes. Il devient impérieux d’intervenir afin d’assurer la conservation de ces espèces.

English title: Diversity and conservation status of woody food species at the periphery of the Lama forest reserve (Benin)

Agroforestry systems, like forests, contribute to the physical and chemical conservation of the soil, to thermal regulation and to the biodiversity conservation. The study aimed to characterize the community of edible woody species in four agroforestry surrounding the central core of the Lama Forest Reserve. A total of 770 square  plots (30m x 30m) were randomly installed in fields, private plantations, home gardens and fallows. In each plot, dendrometric measurements (diameter) were taken on individuals with a diameter ≥ 5 cm at 1.30 m from the ground. Jaccard similarity index and Venn diagram were used to assess the similarity between agroforestry systems. Species density varied significantly from fields to home gardens. The diameter structure of the woody plants showed a predominance of small diameter individuals [5-35 cm [. The home gardens were the only ones gathering individuals of small sizes. A low floristic variation was observed between the systems. It becomes imperative to intervene to ensure the conservation of these species.
