WRITING ACCURACY PERCEIVED BY THE LANGUAGE OUTPUT-BASED TASK
Authors: Indra Sudrajat
Published: April 2022

This study has a purpose to find out the effectiveness of a task, which was exclusively invented for the study, on the students’ writing accuracy. The task, namely Language Output-based Task, is derived from the functions of the language output hypothesis proposed by (Swain, 1985). The three functions of language output are the noticing or triggering function, the hypothesis-testing function, and the metalinguistic or reflective function ((Swain, 1995);(Swain, M., and Lapkin, 1995). In her latest definition, Swain defines language output as an act of producing language either in form of speaking or writing (Swain, 1995). The study chose writing as the productive skill since the existing curriculum as this study conducted emphasized on accuracy in writing. In order to measure the students’ accuracy, the narrative text was involved in the study as it has a moderate level of language features. The samples of the study were the 60 first-year students of two different classes consisting of 30 students in each class. Since this is a pre-experimental study, it implemented pre test and post test to the experimental and control group. The pre and post test were created by involving the target text (i. e. narrative text). The result of the study showed that there was a significant difference between the post-test scores of the experimental group and the post-test scores of the control group. From its result, it was concluded that the Language Output-based task was effective to improve the students’ accuracy (Castro, C. and Wang, 2010; Izumi, 2002).

Published: April 2022

A low regression rate is a major limitation in the hybrid rocket propulsion system. This paper is to study the regression rate characteristics of a cylindrical solid grain with cryogenic propellants. Paraffin (P) fuel is coupled with two types of oxidizers, namely gaseous oxygen (GOX) and nitrous oxide (N2O). ANSYS software is used as the CFD platform to observe the hybrid rocket flow-fields. The modelling values obtained from the pressure, temperature, velocity, and wall heat flux contours are used to calculate the hybrid rocket performance in terms of regression rate, thrust, specific impulse, characteristic velocity, and exit Mach number. The numerical results show that the mass-flow-inlet boundary conditions, initial design feature, and type of propellant play an important role in the enhancement of hybrid rocket performance. Result shows that enhanced of 68 % of the regression rate, 59 % of thrust, 6 % of specific impulse and exit Mach number, and % of characteristic velocity by improved 50% of mass flow rate. Due to the high flame temperature, the GOX/P propellants produce the best hybrid rocket motor compared with the others.

Authors: Maula Inayatul , Zainuddin  , Muhammad Solehuddin
Published: April 2022

AbstractThe idea of ecological boarding school is actually not a new idea in the  of Islamic boarding school. Islamic boarding schools as the oldest educational institutions in Indonesia are already familiar with ecological studies, both in the fields of interpretation of the Qur'an, Hadith, Fiqh, and the yellow book which become the basis of their knowledge. However, it is still theoretical and has not yet fully implemented. This study uses library research in the form of searching the latest books, books and journals. This paper concludes that it is time for Islamic boarding schools to transform their scientific treasures, especially those related to ecology, into a real movement. Islamic boarding schools must return to their identity as agents of social change by utilizing the scientific treasures, their community and human resources they have by creating ecological boarding schools.

Authors: Carrillo-Cortés Sara L. , Claudio-Rizo Jesús A. , Burciaga-Montemayor Nidia G. , Caldera-Villalobos Martín
Published: April 2022

The aim of this work was to study the adsorption properties of interpenetrating polymeric networks (IPNs) based on alginate, collagen, and two different polyurethanes (ACP(HDI), ACP(IPDI)) for the removal of textile dyes from aqueous solutions and wastewaters. The interaction of ACP(HDI) and ACP(IPDI) with methylene blue (BB9), malachite green (BG4), indigo carmine (AB74), and Congo red (DR28) was studied by adsorption kinetics and adsorption isotherms. Concentration profiles revealed a fast removal of dyes from aqueous solutions reaching the equilibrium after 4 h of contact. ACP(IPDI) removed up to 87 ± 0.5% of BG4 and the removal efficiency for the other dyes was lower. Experimental data fit the pseudo-second-order model showing that the removal process is controlled by diffusion. Adsorption isotherms were described by the Freundlich’s model observing concave up isotherms. Results showed that IPNs obtained from the polyurethane containing P(IPDI) cyclic moieties are better for dye removal than those obtained from the P(HDI) acyclic polyurethane.

Published: April 2022

Socio-Economic Status (SES) is an obscure perception of two diverse phases, the sociological phase and the economic phase. The sociological phase includes class or place surrounded by a communal stratification and the financial phase includes assets such as, livelihood, earnings as well as possessions. Tribal women contain multidimensional roles and household tasks in their families but she is still lagging behind. The present study was carried out in Kashmir valley to analyze the Socio Economic Status of tribal women in respective to their categories, educational status and marital status. Out of 2, 19,774 tribal women in Kashmir valley, 1031 tribal women were taken by applying proportionate stratified random sampling technique. To collect information, a standardized scale “Socio Economic Scale” constructed by Kalia and Sahu was administered during the data collection. The results of the present study reveal that tribal women in Kashmir have low socio cultural, economic, health and educational status.

People with chronicle wounds in the skin associated with diabetic neuropathy, a venous ulcer, and burns were invited to participate and signed an informed consent to use a gel-based on collagen-polyacrylate-MOF, which acted as an adjuvant in skin wound healing. The outstanding results of the study indicated that the gel-based on collagen-polyacrylate-MOF, enhances the healing process in short periods of use in patients (promoted by collagen), preventing the appearance of pathogens that hinders the healing (effect promoted by polyacrylate and MOFs). According to the preview results, a further clinical study should be made with a major population.
Echocardiographic parameters for differentiation of balanced from unbalanced forms of complete atrioventricular septal defect
Authors: Vassileva Zornitsa , Kaneva Anna
Published: April 2022

The diagnosis of complete atrioventricular septal defect (CAVSD) relies completely on echocardiography. Different measurements can be used for the differentiation of the balanced from the unbalanced forms of the defect but each of them has limitations and cannot be applied separately. There is no established algorithm ensuring precise classiﬁ cation of the CAVSD as balanced or unbalanced, especially in borderline forms. Based on a protocol, including measurements of a series of echocardiographic parameters used by other investigators, we have managed to identify 4 measurements which when applied in a predictive model allow for correct determination of the form of the CAVSD in 97% of the cases. These parameters are: inﬂ ow angle right ventricle/left ventricle, left atrioventricular valve inﬂ ow, atrioventricular valve index, and ratio between the long axes of the two ventricles.

The Łojasiewicz inequality for free energy functionals on a graph
Authors: Li Kongzhi , Xue Xiaoping
Published: April 2022

Rencently Chow, Huang, Li and Zhou proposed discrete forms of the Fokker-Planck equations on a finite graph. As a primary step, they constructed Riemann metrics on the graph by endowing it with some kinds of weight. In this paper, we reveal the relation between these Riemann metrics and the Euclidean metric, by showing that they are locally equivalent. Moreover, various Riemann metrics have this property provided the corresponding weight satisfies a bounded condition. Based on this, we prove that the two-side Łojasiewicz inequality holds near the Gibbs distribution with Łojasiewicz exponent \begin{document}$ \frac{1}{2} $\end{document}. Then we use it to prove the solution of the discrete Fokker-Planck equation converges to the Gibbs distribution with exponential rate. As a corollary of Łojasiewicz inequality, we show that the two-side Talagrand-type inequality holds under different Riemann metrics.
Novel Noor iterations technique for solving nonlinear equations
Authors: Chairatsiripong Chonjaroen , Thianwan Tanakit
Published: April 2022

The aim of this paper is to propose a novel Noor iteration technique, called the CT-iteration for approximating a fixed point of continuous functions on closed interval. Then, a necessary and sufficient condition for the convergence of the CT-iteration of continuous functions on closed interval is established. We also compare the rate of convergence between the proposed iteration and some other iteration processes in the literature. Specifically, our main result shows that CT-iteration converges faster than CP-iteration to the fixed point. We finally give numerical examples to compare the result with Mann, Ishikawa, Noor, SP and CP iterations. Our findings improve corresponding results in the contemporary literature.
Popularity Prediction for Consumers' Product Recommendation Articles
Authors: Wang Tao , Han Dongmei , Dai Yonghui
Published: April 2022

Consumer product recommendation articles posted in Social Shopping Community (SSC) have become an important source of purchase information for other potential consumers. However, less effort has been put into understanding and predicting the popularity of such a distinctive form of consumer-generated content. In this study, we built a rich and comprehensive dataset comprising author-related features, article-related features, and engagement behavior information collected from post.smzdm.com. We constructed machine learning models to predict article popularity, and used the SHapley Additive exPlanations (SHAP) approach to visualize and explain feature importance in the prediction. The results show that with all identified features, LGBMClassifier gives best results with most evaluation metrics, and that the author-related feature set has better predictive capability than the article-related one. To the best of our knowledge, ours is the first study to investigate the popularity of consumers’ product recommendation articles in SSCs.

COVID-19, air quality and space monitoring
Authors: Tourre Yves M. , Paulin Mireille , Dhonneur Gilles , Attias David , Pathak Atul
Published: April 2022

Due to the worldwide spread of the coronavirus disease 2019 (COVID-19), human mobility and economic activity have slowed down considerably since early 2020. A relatively high number of those infected develop serious pneumonia leading to progressive respiratory failure, system disease and often death. Apart from close human-to-human contact, the acceleration and global diffusion of this pandemic has been shown to be associated with changes in atmospheric chemistry and air pollution by microscopic particulate matter (PM). Breathing air with high concentrations of nitrogen dioxide and PM can result in over-expression of the angiotensin converting enzyme-2 (ACE-2) leading to stress of organs, such as heart and kidneys. Satellite monitoring can play a crucial role in spatio-temporal surveillance of the disease by producing data on pollution as proxy for industrial activity, transport and traffic circulation. Real-time monitoring of COVID-19 in air and chemical pollution of the atmospheric boundary layer available from Earth-observing satellites commuting with Health Information Systems (HIS) would be useful for decision makers involved with public health.

Feto a rischio per iperplasia surrenalica congenita
Authors: Spagnolo Antonio G. , Di Pietro Maria Luisa
Published: April 2022

Gli autori discutono il caso clinico di una donna gravida di 21 anni, con un figlio maschio già nato affetto da una iperplasia surrenalica congenita dovuta al deficit di 21-idrossilasi. Nel corso dell'ottava settimana di gravidanza viene iniziata la somministrazione di glucocorticoidi nel sospetto che il feto potesse essere affetto dalla stessa malattia dell'altro figlio: la terapia viene continuata dopo conferma della malattia effettuata mediante diagnosi prenatale con prelievo dei villi coriali (CVS) alla 10a settimana. Tre problemi etici sono considerati: 1) il grado di accettabilità del rischio connesso con metodiche diagnostiche come la CVS; 2) il rapporto rischi/benefici per il nascituro e per la madre in relazione alla terapia attuata; 3) l'efficacia di una terapia che fosse iniziata dopo una diagnosi prenatale più tardiva ma effettuata con una tecnica meno rischiosa e più sicura, come l'amniocentesi. E' proposta, infine, la posizione personale degli autori in merito alla decisione etica in un caso come questo.

The contribution of family physicians to district health services in South Africa: A national position paper by the South African Academy of Family Physicians
Authors: Family Physicians South African Academy Of
Published: April 2022

The purpose of this position paper by the South African Academy of Family Physicians (SAAFPs) is to inform decision making on human resources for health policy in South Africa and the placement of family physicians (FPs) in the district health system. National policies have been marred by misunderstanding of the roles and contribution of FPs; and there is unhelpful variability in how FPs are positioned in the health services between provinces. In the private sector, medical aid schemes have discriminated against FPs by failing to remunerate them as specialists and to recognise their scope of practice.

Oesophageal cancer in South Africa: A scoping review
Authors: Ferndale Lucien , Aldous Colleen
Published: April 2022

Background: Oesophageal cancer is an aggressive cancer that is endemic in certain parts of South Africa where it is the second commonest cause of cancer-related deaths. Yet, there is a paucity of research on the topic from the area.Aim: This article aimed to assess the body of literature on clinical and epidemiological research on oesophageal cancer from South Africa and identify key research gaps.Methods: We conducted a scoping review of research on oesophageal cancer in South Africa. We performed a search of databases as well as manual searches after cross-referencing from selected articles. We selected all appropriate articles published up to the end of 2020 and excluded genetic and laboratory-based studies without clinical components.Results: We identified 81 articles that were published from 1957 to 2020. There was a significant decrease in the number of publications after the year 2000 and studies on the surgical management are non-existent after 2000. We found inconsistencies in the data regarding the incidence of oesophageal cancer in South Africa. Late presentation appears to be a huge factor in South Africa resulting in a poor prognosis. The largest research gaps included studies on incidence, curative management, follow-up after treatment and screening.Conclusion: There needs to be a strong drive towards research on oesophageal cancer in order to first establish the burden of disease in South Africa and thereafter investigate ways to diagnose the disease and institute appropriate management earlier.
Enriched pre-Lie operads and freeness theorems
Authors: Dotsenko Vladimir , Foissy Loïc
Published: April 2022

In this paper, we study the

\mathcal{C}

-enriched pre-Lie operad defined by Calaque and Willwacher for any Hopf cooperad

\mathcal{C}

to produce conceptual constructions of the operads acting on various deformation complexes. Maps between Hopf cooperads lead to maps between the corresponding enriched pre-Lie operads; we prove criteria for the module action of the domain on the codomain to be free, on the left and on the right. In particular, this implies a new functorial Poincaré–Birkhoff–Witt type theorem for universal enveloping brace algebras of pre-Lie algebras.

Authors: S. Adewale Tunde , O. Abosede Olufunso
Published: April 2022

Co-crystal engineering is an important aspect of pharmaceutical development as it enables the obtainment of structural varieties of drug forms of same active pharmaceutical compounds while maintaining or improving physico-chemical and therapeutic activities of the active pharmaceutical compounds. In this work, we report the green synthesis of two co-crystals of fluconazole with succinic acid and urea. White block single crystals were obtained after slow evaporation of ethanolic solution of fluconazole (FLU) with the coformers (succinic acid and urea) in 1:1 molar ratio and were characterized using UV and Fourier Transform Infrared (FTIR) spectroscopy. FTIR spectra of the co-crystals confirms the formation of the co-crystals in solid state with the appearance of diagnostic FTIR bands of both fluconazole functional groups and those of the coformers (succinic acid and urea) in succinic acid-fluconazole (SFLU) and urea-fluconazole (UFU) respectively. UV-Vis spectra also features the π-π* absorption maxima of fluconazole in the co-crystals, providing additional evidence for the formation of the co-crystals.

Fungal strains are widely used for the cleaning of soil, sediments, groundwater, surface water, and theecosystem. The presence of extracellular enzymes in fungi facilitates the process of bioremediation of textile dyes. Thisstudy was conducted to observe the quality of water being released from textile dyes industries and also the capabilityof some fungal strains which can remediate these dyes by showing the tendency of their resistance. Samples of waterwere collected from the polluted area surrounding the textile dyeing industries in Lahore. In the process of isolation,Potato Dextrose Agar (PDA) medium was used to verify the fungal growth. Fungal strains were purified, and themorphological characterization of fungal strains was carried out at 10X and 100X by using a magnification microscope.The fungal strains, such as Aspergillus niger, Aspergillusoryzae, and Aspergillusflavus were identified. The stress offour types of dyes was given to each fungal strain. The results showed that Aspergillusoryzae was one of the moststable, non-toxic, and resistant fungal species against the high stress of dyes as compared to other species.

The 2-D seismic and well log data set is composed of three seismic lines and well log data of Chak 66–1. Five horizons have been marked with the help of well to seismic tie namely tops of Ranikot, Parh, upper Goru, lower Goru, basal and top massive sands, and out of which basal and massive sands are the objective focus of the present study. Based on seismic data, the study area is characterized by normal faults showing NW–SE dipping trend. Horst and graben structural features are prominent on the seismic lines, which indicated the extensional tectonic regime. Time–depth contour maps and 3D surfaces of objective horizons depict their actual spatial distribution in this area. Wireline logging analysis revealed the physical properties of both basal and massive grains of sand, as 17% effective porosity, 25% average volume of shale (Vsh), 40% water and 60% hydrocarbon saturations for basal sands, Whereas, 16% effective porosity, 35% Vsh, 30% water and 70% hydrocarbon saturations are interpreted for massive sands. Cross–plots of Nphi–Dt and Dt–Rhob also identified that both areas of sand are clean, gas–saturated and have the potential to produce hydrocarbons.

Bela Ophiolite and suture zone host several types of gemstones in the underlain and overlain rocks such as garnet (demantoid and almandine), quartz, brucite, malachite, chrysocolla, azurite, calcite, natrolite, green chert, jasper, serpentine, agate, epidote, augite and prehnite. However, the rare gemstones including demantoid garnet are found as dodecahedron green crystals associated with the altered peridotite rocks such as serpentinite. Brucite is found in the botryoidal habit in the ultramafic rocks of Bela Ophiolite associated with the chromite mines in the Baran Lak and Amorzai area of Wadh in the host rock dunite. The serpentine is found in several locations associated with the altered ultramafic rocks formed after the serpentinization of peridotite. Furthermore, one of the rare gemstones such as petroleum and diamond quartz is formed due to the hydrothermal intrusion in the sedimentary rocks such as limestone; calcite also occurs in limestone as dogtooth crystals. While azurite, malachite and chrysocolla are formed as secondary deposits in the oxidized zone of copper and sulphide mines in the Manjawi, Nal and Sonaro associated adjacent to basalt. Moreover, epidote is found as green crystals having porphyritic texture in the host rock granite mainly in the Bakhalo area, Wadh. Agate, jasper, green chert and several other kinds of chert are found associated with the basalt chert unit in the mélange and gossan. In addition to that natrolite is found in the Nal ophiolite mainly in the Hazarghanji town found associated with the cracks and vugs of dolerite dykes as fibrous and cylindrical crystals. In metamorphic sole rocks of Bela Ophiolite in the Sonaro area, marble and quartzite are associated with the metamorphic rocks such as greenschist and amphibolite facies that are formed during the e volution period of the ophiolite. In pegmatite gabbro, the elongated and prismatic black crystals of augite are found in the host rock gabbro near the Ornach cross area, and the prehnite gemstone is found associated with the basalt and gabbroic rocks transition zone in the Ornach area.

Rice husk is one of the utmost obtainable feedstock for renewable energy production and can contribute to resolving energy scarcity and environmental problems. Appropriate knowledge of the rice husk's physiochemical properties is essential for the approach of thermochemical conversion systems. The present study delivers data on proximate and ultimate analysis and heating values of rice husk collected from different regions of Sindh, Pakistan. Moisture content was found low ranging between 12.76% to 13.50% (Mean 12.98%), higher volatile matter in the range of 55.77% to 62.88% (Mean 61.19%) and ash particles of 14.50% to 16.48% (Mean 15.20%). The lower concentrations of nitrogen, 0.37% to 1.31%, (Mean 0.70%) and sulfur, 0.02% to 0.19%, (Mean 0.11%) environmentally deal with more appropriate fuel properties. The heating value of rice husk ranges varied from 5,276.33 to 6,237.13 Btu/lb (Mean 5,859.87 Btu/lb). The significant values of the rice husk samples indicated that the locally available renewable resources can be transformed into an extensive amount of energy products at a small level from active conversion techniques. Therefore, rice husk can be deliberated as appropriate fuel for energy generation and can be considered as an environmentally friendly and economically feasible fuel that helps to decline harmful pollutions.

Abstract
One of the most crucial consumer behaviors needed to be well understood by the retailer is impulse buying. Customers at impulse are prone to buying beyond their shopping mission, which, in turn, may lead to an increase in sales of the store. This study presents the effects of shelf position in a supermarket on impulse buying among Filipino Millennials. It focuses on comparing the Filipino consumers’ buying behavior based on their demographic characteristics and how relevant these are to impulse buying. The study led to the following outcomes: Horizontal and vertical shelf positions influence impulse buying. In addition, gender, civil status, and income do not have an effect between shelf position and impulse buying. Age, however, positively moderates the effect of horizontal shelf position and negatively moderates the effect of vertical shelf position on impulse buying. Educational attainment also positively moderates the effect of vertical shelf position on impulse buying. Thus, the influence of horizontal and vertical shelf position on impulse buying among Filipino Millennials is moderated to some extent by their demographic characteristics. The study used descriptive and inferential statistics covering the relationship between impulse buying, shelf position, and demographics through snowball sampling. The study has a sample size of 225.
