Published: August 2021

Background:

Gastric adenocarcinoma (GA) is a serious malignancy with growing incidence and mortality rate worldwide. The objective of the present study was to determine whether 7-geranyloxycoumarin, a natural monoterpene coumarin, could induce anticancer effects, in single use and/or in combination with anticancer drugs and ionizing radiation, on GA cells.

Materials and Methods:

7-geranyloxycoumarin was synthesized by a reaction between 7-hydroxycoumarin and transgeranyl bromide. MKN45 cells were treated with 7-geranyloxycoumarin, and the viability of cells was determined by resazurin. Apoptosis was then evaluated by flow cytometric analysis using annexin V and propidium iodide, and the expression of P53 and BCL2 was analyzed by quantitative polymerase chain reaction (qPCR). Combinatorial effects of 7-geranyloxycoumarin with 5-fluorouracil (5-FU), cisplatin (CDDP), and X radiation were also evaluated.

Results:

Assessment of cell viability indicated that 7-geranyloxycoumarin induced its toxic effects in a time- and dose-dependent manner. This was confirmed by the detection of apoptotic cells, and qPCR results revealed a significant downregulation in BCL2 expression. Although combinatorial use of 7-geranyloxycoumarin + 5-FU or + CDDP did not improve cytotoxicity of anticancer drugs, significant increase in the effectiveness of applied radiations was detected upon pretreatment with 7-geranyloxycoumarin.

Conclusion:

Our findings provide valuable insights into single and combinatorial effects of 7-geranyloxycoumarin on the GA cells.

PurposeTo evaluate the role of postmastectomy radiation therapy (PMRT) in patients with node-negative breast cancer of 5cm or larger tumors undergoing mastectomyMaterials and MethodsMedical records of 274 patients from 18 institutions treated with mastectomy between January 2000 and December 2016 were retrospectively reviewed. Among these, 202 patients underwent PMRT, while 72 did not. Two hundred and forty-one patients (88.0%) received systemic chemotherapy, and 172 (62.8%) received hormonal therapy. Patients receiving PMRT were younger, more likely to have progesterone receptor-positive tumors, and received adjuvant chemotherapy more frequently compared with those without PMRT (p <0.001, 0.018, and <0.001, respectively). Other characteristics were not significantly different between the two groups.ResultsWith a median follow-up of 95 months (range, 1-249), there were 9 locoregional recurrences, and 20 distant metastases. The 8-year locoregional recurrence-free survival rates were 98.0% with PMRT and 91.3% without PMRT (p=0.133), and the 8-year disease-free survival (DFS) rates were 91.8% with PMRT and 73.9% without PMRT (p=0.008). On multivariate analysis incorporating age, histologic grade, lymphovascular invasion, hormonal therapy, chemotherapy, and PMRT, the absence of lymphovascular invasion and the receipt of PMRT were associated with improved DFS (p=0.025 and 0.009, respectively).ConclusionLocoregional recurrence rate was very low in node-negative breast cancer of 5cm or larger tumors treated with mastectomy regardless of the receipt of PMRT. However, PMRT was significantly associated with improved DFS. Further investigation is needed to confirm these findings.

For a limited time only, SAE is offering a 20% discount off the list price of $70. Purchase today for $56. What is acoustics? What is noise? How is sound measured? How can the vehicle noise be reduced using sound package treatments? Pranab Saha answers these and more in Acoustical Materials. Acoustics is the science of sound, including its generation, propagation, and effect. Although the propulsion sources of internal combustion engine (ICE) vehicles and electric motor-powered vehicles (EV) are different and therefore their propulsion noises are different, both types of vehicles have shared noise concerns: Tire and road noise Wind noise Vehicle noise and vibration issues have been there almost from the inception of vehicle manufacturing. The noise problem in a vehicle is very severe and is difficult to solve only by modifying the sources of noise and vibration. Sound package treatments address the noise and vibration issues along the path to reduce in-cabin noise. In Acoustical Materials, readers will grasp the science of reducing sound and vibration using sound absorbers, sound barriers, and vibration dampers. Sound provides information on the proper operation of the vehicle, but if unchecked, can detract from the consumer experience within the vehicle and create noise pollution outside the vehicle. Acoustical Materials provides essential information on the basics of sound, vehicle noise source, how these are measured, how vehicle owners perceive sound, and ultimately, how to solve noise problems in vehicles using sound package materials.

Published: August 2021

The phenomenon of northern pile dwellings has been found in different geographical zones and landscapes of the Circum-Baltic region: in sea landscapes and on the shores of inland lakes and rivers. Inland sites were established in specific lacustrine landscapes, appearing within former post-glacial basins. The pile dwellings revealed here are characterized by different types of wooden buildings, including structures with raised floors. They are dated to the 4th millennium BC to 4th century BC in Central Europe and the Baltics, and to the end of the 4th to end of the 3rd millennium BC – in NW Russia and Belarus. They appeared in major cases independently and followed different cultural trajectories. The article presents an overview of a number of sites which can be attributed to pile dwelling settlements distributed in the Circum-Baltic area. It discusses particular features of their construction, traits of material culture, and site location patterns.

Published: August 2021

Background: Controlling infections in healthcare facilities is necessary for reducing infection transmission. There is limited data on the status of Infection Prevention and Control (IPC) programme in healthcare facilities in Rivers State. An assessment of IPC implementation in health facilities in Rivers State was therefore conducted.Methods: In this cross-sectional study, stratified sampling technique was applied to select 99 healthcare facilities. Health personnel in-charge of selected facilities were interviewed using the validated Infection Prevention and Control Assessment Framework (IPCAF) tool. It was modified to focus on four out of eight core components areas and graded using the World Health Organization IPCAF guidelines.Results: Twenty (20.2%) facilities had IPC programmes with clearly defined objectives and activity plans. A copy of the IPC guidelines was available in 56 (56.6%) facilities, however, only 13 (13.1%) monitored implementation of the guidelines. Forty (40.4%) facilities had healthcare workers that were trained based on updated IPC guidelines. Supply of personal protective equipment was adequate in 29 (29.3%) facilities and a mixed method of healthcare waste disposal was practiced in 46 (46.4%) facilities. Overall, 56 (56.6%) of the facilities had scores within the basic IPC level of practice while 43 (43.4%) had scores within the intermediate level of IPC practice.Conclusion: Findings from this study indicate that IPC committees should be set up in all healthcare facilities with the obligation of updating IPC guidelines, training healthcare personnel, and implementing IPC activities in respective healthcare facilities.

The aim of the study was to evaluate the carcass characteristics, proximate composition, and sensorial attributes of meat from sheep fed diets in which buffelgrass silage replaced corn silage. Thirty-two intact male crossbred Santa Inês sheep with an average live weight of 20.09 ± 2.0 kg were housed in individual stalls and allotted at random to four treatments in which corn silage was replaced by buffelgrass silage at the levels of 0 (control), 33.3%, 66.6%, and 100%. After an adaption period of 10 days, the sheep were fed for an additional 61 days. Feed was offered ad libitum and corn silage comprised 60% of the diet for the control group. Carcass characteristics, non-carcass components and meat quality were evaluated. Hot carcass yield, cold carcass yield, true carcass yield, trimmings, fat weight, and mesenteric and omental fat weight were highest for the control group (P <0.05). Loin eye area had a quadratic response (P =0.02), with the largest areas being observed in animals fed the diet containing 66.6% buffelgrass silage. Liver weight (P <0.01), luminosity of the meat (P <0.05), and cooking loss (P <0.05) likewise had nonlinear responses to the concentration of buffelgrass silage in the diet. The treatments did not have significant negative influence on the nutritional and organoleptic characteristics of the meat.

Published: August 2021

Ensuring food safety is a legal obligation of the manufacturer or of the entity that places the product on sale. Traceability is one of the tools that are used to ensure food safety. It allows the withdrawal of a dangerous or non-compliant product from the market and determines the source of a threat. The aim of the study was to compare the functioning and effectiveness of traceability systems in selected approved meat industry plants. The system functioning in a large meat processing plant, in which the circulation of documents was implemented in a computer system, was compared with two smaller ones, in which paper documentation was carried out, but supported by a computer system. In these plants, the traceability system was based on internal procedures. Properly developed traceability procedures and simulations support and enable response in a crisis. Computer systems streamline and facilitate the traceability process. However, the comparative analysis showed that the use of paper records allowed for efficient identification of the source of the threat. The possibility of performing product traceability was confirmed in these plants. Internal markings and codes and documentation flow, staff training, and awareness proved helpful.

To evaluate the effect of a production system and feeding regimen on meat quality attributes of Naked Neck chickens, a total of 150 cockerels at 18 weeks old (1625 ± 70 g) were collected from 10 treatment groups with five replicates of three birds. The factorial arrangement of treatments consisted of two production systems (intensive and free-range) and five nutritional regimens, namely 100% commercial feed; 75% commercial feed plus 25% kitchen waste; 50% commercial feed plus 50% kitchen waste; 25% commercial feed plus 75% kitchen waste; and 100% kitchen waste. Carcass traits, meat quality, and meat organoleptic were found to differ significantly among production systems, feeding regimens, and their interaction. Higher liver weight was observed in birds reared under an intensive system. Higher gizzard weight was noted in birds fed with 100% kitchen waste, whereas lower gizzard weight was observed in birds fed the commercial diet. The meat from cockerels fed with 75% kitchen waste was most yellow, whereas the meat from the birds fed with 100% kitchen waste was least yellow. At two hours after slaughter, pH of the meat was highest in birds fed 50% kitchen waste and lowest in birds fed 100% kitchen waste. The interaction of production system and feeding regimen was significant for overall acceptability score. In conclusion, Naked Neck chickens performed equally well under intensive and free-range systems, irrespective of the level of kitchen waste that they were fed.

Published: August 2021

The goal of this research was to gain understanding of in vitro methane (CH4) production from the cecal contents of White Roman geese under various incubation conditions. Five experiments were conducted to ascertain the effects of i) incubation time, ii) pH, iii) the addition of formic acid to the culture media, iv) temperature, and v) the addition of salt to the nutritive liquid. Methane production increased significantly with the supplementation of formic acid in the culture fluid (Experiment III). Additionally, CH4 production Experiment V was higher than that without saline. In contrast, low CH4 production occurred under acidic conditions (pH ≦5.4) and at temperatures higher or lower than typical bird body temperature (43 °C) without formic acid and saline solution in the culture media. Since bird body temperature cannot be controlled easily, approaches such as maintaining cecum fluid at low pH and preventing the formation of formic acid by adjusting the recipes of feeds could be considered for controlling in vivo CH4 production from the intestinal tract digesta of geese.

The aim of the research was to determine whether enrichment of the atmosphere in an incubator with carbon dioxide (CO2) and oxygen (O2) and eggshell thickness (EST) affected embryonic death (ED), hatchability of fertile eggs (HFE) and hatching time (HT). A total of 320 Ross 308 eggs were used and the experiment was repeated twice. Eggshell thickness was classified as thin (<31 μm), medium (31 - 32 μm) and thick (>32 μm). The incubators were operated with their internal atmosphere enriched with CO2 (1.57% CO2; 20.23% O2) or O2 (0.50% CO2; 22.44% O2). Embryonic death, HFE and HT data were monitored at three periods, namely early (<486 hours), middle (486 - 492 hours), and late (492 - 510 hours). Early ED, late ED and hatchability of fertile eggs were not affected by EST or by the incubator’s internal atmosphere (P >0.05). Thus, O2 supplementation to the incubator was deemed unnecessary at 822 m altitude. There was a highly significant interaction between EST and HT. Eggs with shells 31 to 32 μm thick hatched at an appreciably greater rate between 486 and 492 hours of incubation (17%) than eggs with thicker (0.6%) or thinner (0.4%) shells in both the CO2 and O2 enriched atmospheres. The hatching rate was significantly higher in the eggs with an intermediate EST than in thick-shelled eggs. A greater proportion of eggs hatched at the late HT as opposed to earlier, regardless of EST.

Authors: Çayan H. , Şahin A.
Published: August 2021

This study was conducted to determine egg yield performance and quality, animal partiality to poultry meal, and consumer preferences for eggs produced by various feeding methods. A total of 72 Nick Brown laying hens, aged 22 weeks, were offered three feeding methods with 24 replicates per treatment and one hen per experimental unit. These methods consisted of i) vegetarian (no poultry meal), ii) omnivorous (5% poultry meal), and iii) a choice between vegetarian and omnivorous. Feed and water were provided ad libitum. The study lasted for 10 weeks. Feeding methods did not affect feed intake, feed conversion ratio, egg yield, and egg quality. However, they affected the malondialdehyde (MDA) value of eggs on the 42nd day of storage significantly (P <0.05). The highest MDA value was obtained from the eggs of ‘omnivorous’ hens. More hens (51.4%) in the choice group preferred omnivorous feed to ‘vegetarian’. Panellists found organoleptic differences among sample eggs from hens subjected to various feeding methods. They reported that the eggs obtained from vegetarian hens were preferable. The conclusions were that i) no feeding method changed egg yield performance and quality, ii) omnivorous feeding shortened the shelf-life of eggs, iii) hens with a choice of feed did not reject the omnivorous diet, but increased their intake, and iv) the panellists disliked eggs from the omnivorous hens. Finally, these preferences should be considered in legislation for poultry feeding and animal husbandry.

Published: August 2021

The research aimed at assessing the effects on nutrient digestion and ruminal fermentation by goats of a complete feed block (CFB) that incorporated agro-industrial by-products that were high in fibre and cellulolytic bacteria. Three Kacang goats, a native Indonesian breed, were used in a 3 × 3 Latin square experimental design with i) CFB without microbes (control), ii) CFB containing 1% Pseudomonas aeruginosa and 1% Acinetobacter baumannii, and iii) CFB containing 2% P. aeruginosa and 2% A. baumannii. Microbes in the CFBs consisted of lactic acid bacteria, yeast and cellulolytic bacteria that ranged from 106 to 108 cfu/g. The goats were fed each day at 08h00 and 16h00. The inclusion of P. aeruginosa and A. baumannii at 2% level reduced both neutral detergent fibre (NDF) and acid detergent fibre compared with other treatments. Goats fed on CFB with microbes had higher (P <0.01) digestibility of organic matter (OM) and NDF compared with control. The addition of P. aeruginosa and A. baumannii at 2% level increased (P <0.05) ruminal ammonia nitrogen (N-NH3), acetate, and total VFA. However, goats fed on CFB with microbes had lower (P <0.05) urinary N excretion, which improved (P <0.05) N retention compared with the control. It was concluded that a combination of lactic acid bacteria, yeast and cellulolytic bacteria in the CFB could modify fermentation in the rumen and increase the use of nitrogen in goats.
Modelling lactation curves for fat-to-protein ratio of milk in the first three lactations of Polish Holstein-Friesian cows
Authors: Satola A.
Published: August 2021

Among milk traits, fat-to-protein ratio (FPR) is considered a potential measure of a cow’s energy status and is one of the selection criteria necessary to improve metabolic stability. Further genetic analyses require an appropriate model that describes the pattern of FPR changes throughout lactation. The objective of the study was to examine five mathematical functions to describe the lactation curve for FPR in the first three lactations of Polish Holstein-Friesians. The dataset contained FPR records for 5690 cows in the first lactation, 4081 cows in the second, and 2636 cows in the third lactation based on 48908, 34706, and 22097 test-day (TD) records, respectively. Using the MIXED procedure of SAS statistical analytics software, ten linear models (five with fixed effects only, and five with the additional random effect of cow) were fitted to the TD records. The goodness of fit was tested with Akaike's information criterion, residual variances and the correlation coefficient between the actual and estimated values. The model proposed by Ali and Schaeffer (1987) had the best fit to FPR in the first three parities, and the model of Wilmink (1987) provided the worst fit. The correlation coefficient between the actual and the estimated values of FPR was higher for models that included the random cow effect compared with models without this effect.

The objective of this research was to evaluate lamb diets with a high proportion of concentrate and various levels of physically effective neutral detergent fibre (NDF) using tropical ingredients. Four diets were formulated: D1 with 16.5% physically effective NDF (peNDF), D2 with 21.4% peNDF, D3 with 23.3% peNDF, and D4 with 24.6% peNDF. Twenty male Santa Inês lambs at four months old with an average liveweight (LW) of 18.6 ± 3.4 kg were fed for 49 days. There were no differences (P >0.05) among the diets in dry matter (DM) intake. Crude protein (CP) intake, relative to either LW or metabolic live weight (LW0.75) or LW, was greater (P ≤0.05) for D2 and D3 than for D1 or D4. Lower (P ≤0.05) NDF intake, relative to LW0.75 or LW, was lower for D1 than for the other diets. Selection indexes (SIs) were similar (P >0.05) among diets. Animals that consumed D1 had less (P ≤0.05) rumination time per bolus. Meaningful variations were not observed in performance and efficiency of finishing lambs that were related to differences in peNDF among the diets. Santa Inês lambs were able to adapt to diets with low levels of peNDF by increasing rumination time as a consequence of increased fibre consumption and greater particle size selection.

Published: August 2021

A systematic review of the literature was carried out to perform a meta-analysis to assess effects of age at weaning on the performance of piglets in the range of 14 to 42 days old. This step consisted in defining the databases and keywords to be employed in searching for papers for the meta-analysis. To that end, the databases Capes Publication Portal and Google Scholar were searched for researches published from 2001 to 2019. After the acceptance and exclusion criteria had been defined and applied, 28 papers were selected. The data were collected with Excel® software of Microsoft Office for later statistical analysis. Orthogonal polynomial contrasts were used and the linear and quadratic regression equations were fitted with hypotheses tested at the 5% significance level. The results confirmed the disadvantages of early weaning and the benefits of weaning at around 28 days old. In the farrowing phase, piglets weaned after 35 days had lower daily weight gain (DWG) (P =0.002) than those weaned at 27 days. The derivative of the regression of DWG while nursing on age revealed that a weaning age of 26.34 days yielded the maximum DWG among the ages assessed. After weaning, the maximum DWG was achieved by weaning piglets at 32.26 days. Given the performance of piglets in the farrowing and nursery phases, the results of this meta-analysis indicated the best weaning age was between 26 and 32 days.

Thuma Mina - an Isaiah 6:8 perspective in crossfire with Step-aside: SA ruling party’s moral restoration efforts
Authors: Thinane Jonas Sello
Published: August 2021

This article builds on the excellent article by Prof. Kgatle and Mashau who examined the
prospects and success of the presidency of Cyril Ramaphosas by reflecting on the concept of Thuma Mina. In this article, Ramaphosas Thuma Mina's manifesto is placed in the same restorative context as the implementation of the African National Congress (ANC) step-aid resolution. Almost 27 years of democracy today since the ANCs came to power in South Africa in 1994, and yet members' moral values continue to decline, as reflected in Gwede Mantashe's devastating Organizational Diagnostic Report. This paper reflects the concept of Thuma Mina at Isaiah 6: 8 as redirected into politics by Cyril Ramaphosa to fight corruption in collaboration with the resolution of the 54th Conference. The Thuma Mina Group's implementation of StepAside threatened the unity of the ANC when the then suspended ANC General Secretary suspended his own suspension to suspend ANC President Cyril Ramaphosa. If the Magashule group succeeds in flaunting the party rules and rejecting the Step-Aside policy, this will lead
to a political catastrophe. This paper uses two disciplines (theology and politics) to shed light on the prospects of Thuma Mina as advocated by President Cyril Ramaphosa, along with the fair implementation of the ANC's Step Aside resolution. This study is important as it provides a more concise understanding of the concept of Thuma Mina campaign.

El propósito de este ensayo es disertar sobre las relaciones entre la Resiliencia y la Neurociencia a partir de sus implicaciones en el contexto educativo. Se parte de la premisa central que la realidad educativa tiene un gran apoyo en la neurociencia y es a través de la resiliencia que le damos un sí a la vida; por lo tanto, la educación debe sacar la mejor versión del estudiante, los cuales deben motivarse por escenarios innovadores focalizando a la educación hacia la flexibilidad cognitiva, imaginación y creatividad. Como conclusión se plantea la necesidad de un escenario ideal sería lograr que en la formación académica de docentes y todos aquellos profesionales que tengan una relación directa con la educación, las emociones y los aprendizajes, se incorporaran conocimientos en neurociencias, porque no todos los procesos de enseñanza aprendizaje son iguales y teniendo en cuenta la plasticidad del cerebro, es posible adaptar más eficazmente ese proceso.
Educación ambiental y ruralidad: Reflexiones para el contexto ecuatoriano
Authors: Veracierto Delgado Ruben Dario , Ormaza Cevallos Miguel Giancarlo , Armas Víctor Hugo
Published: August 2021

Ecuador es el país más deforestado del mundo en proporción a su superficie de 256.370 Km cuadrados. Además de la explotación petrolera, que se ha visto desplazada en los últimos años, preocupa la expansión de la minería a gran escala que se proyecta en zonas rurales del país. Modificar esa tendencia debe ser el principal reto para la educación ambiental. Cuando se destruyen los bosques, para expandir la frontera agrícola o minera, se genera una afectación sobre todos los recursos naturales. Sobre la base de este planteamiento, surge la inquietud del presente ensayo, el cual se centra en analizar la incidencia de la educación ambiental como instrumento de transformación social y gestión de los recursos naturales en los espacios rurales. Igualmente, se reflexiona sobre la naturaleza de la educación rural, desde distintas miradas para la comprensión del proceso enseñanza aprendizaje in situ, transformador y contextualizado a las especificidades socioeconómicas, culturales y cognitivas de los niños y jóvenes de las zonas rurales. Se concluye que la educación ambiental debe ser una educación para la participación y, en última instancia, para la autogestión del medio, como la manera óptima de conservar la mega diversidad ecuatoriana.
A Laudato Si em chave a Ecoteológica: uma interface entre fé e vida
Authors: Mamede José Flávio
Published: August 2021

RESUMOA presente pesquisa objetiva fazer uma relação entre a ecologia e a encíclica Laudato Si do papa Francisco (2015). Desse modo, apresenta-se uma leitura da encíclica Laudato Si a partir da ecoteologia latino-americana, defendendo a tese fundamental da teologia da libertação que é a fé unida à vida. Trata-se de uma opção fundamental pelos pobres. Nesse sentido, o conceito de pobre comporta todo o planeta terra ou “casa comum”, bem como toda humanidade. Tanto o planeta terra quanto a humanidade passam por uma verdadeira crise com muitas faces. A exploração do meio ambiente por meio de um progresso tecnológico desordenado tem provocado um verdadeiro desequilíbrio ecológico e social com graves prejuízos para com todos os seres, atingindo com mais veemência os mais pobres. O papa Francisco propõe uma ecologia integral que valorize todos os seres. Portanto, a Laudato Si se torna uma proposta planetária, isto é, um programa ecoteológico em que a teologia se torna prática libertadora.

ABSTRACT

The crime of theft that often occurs in society is not only committed by adults but also children. The purpose of this study is to find out the factors that cause children to commit theft, how to apply restorative justice to crimes committed by children and what the future concept will be so that the diversion process runs properly. The method used is normative juridical through a statutory approach. The legal materials consist of the 1945 Constitution, Law Number 11 of 2012 concerning the Juvenile Criminal Justice System, Secondary materials consist of books, journals related to research. The data processing technique is obtained from primary and secondary legal materials which are processed in such a way as to be used as material to be studied. The finished data analysis is carried out as an effort to find and organize systematically in order to increase understanding of the subject matter studied. The results of this study are factors that cause children to steal because of endogenous factors from within themselves besides factors from the family and the surrounding environment that can influence children to steal and the last is economic factors and mass media, in addition to the application of restorative justice for criminal acts. theft committed by children is contained in Article 7 of Law Number 11 of 2012 concerning the juvenile criminal justice system, but in the Act on the juvenile criminal justice system there are several articles that are considered harmful, therefore for the future concept that the rules are changed so that everything is fair not only the perpetrators but also all the injured parties.

Published: August 2021

The health crisis that the world is experiencing with the Covid-19 virus has not really created new challenges; it has made those we were facing stronger, as it has made us more aware of the need to protect our environment. All countries are seeking to organise an energy transition to a low-carbon society, but not all have the same ambitions, the same constraints or the same means to achieve it. Several challenges need to be addressed.

Purpose: The purpose of the study was to explore the influence of Islamic auto financing instruments on financial performance of commercial banks in Isiolo County Kenya.

Methodology: This study used descriptive research design. The respondents were customer service officers and loan officers in the ten commercial banks in Isiolo County. They were be selected using census method. Data collection was done using closed-ended questionnaires and secondary data collected through analysis of report from 2017 to 2020. To ensure validity and reliability, pre-testing of questionnaires was done at Kenya Commercial Bank in Meru town. Coded data in SPSS 24.0 computer program analyzed quantitative and qualitative data using the descriptive statistics such as mean, percentage and standard deviation. Multiple regression was used to test hypothesis of the study. Tables, graphs and detailed explanations were used to present the final results of the study.

Results: Options had a statistically significant relationship with financial performance. The respondents agreed that the lending terms of Islamic automobile financing have attracted diverse clients (mean of 4.78). However, in comparison with other statements, the respondents did not tally that having sharia committee in disbursing car loans had enabled clients have confidence with the automobile loans (mean of 3.83). The R value was 0.862 and R-square of 0.743. This indicated that Islamic auto financing instruments’ level of contribution towards financial performance was 74.3%. The Durbin- Watson value was 1.969. This value lied between 0 and 2 hence indicating that there was a positive correlation between auto financing instruments and financial performance. The significance value was 0.000 which was below 0.05 hence Islamic Auto financing instruments had a significant influence of financial performance. In addition, the respondents did not tally that having sharia committee in disbursing car loans had enabled clients have confidence with the automobile loans. This proved that the confidence that clients had on auto financing, was not purely on the nature and process of administration of the financing but also due to reliability.

Unique contribution to theory, policy and practice: The study recommends that auto financing should be provided reliably by ensuring all client concerned are amicably handled by the banking staff. The various car loan officer should be trained on good customer service to as to ensure they sell well their products without necessarily losing new clients. The bank management should also diversify auto financing to cater for all categories of vehicles for expansion of their client base.

Enhancing the learning experience of primary school learners through the utilisation of a hybrid web-based learning model : a case study of learning mathematics of areas and perimeters
Authors:   , Naidoo Nirendran
Published: August 2021

The use of web based learning in primary schools has been neglected. The aim of the study is the design of a hybrid web based learning model for primary school mathematics especially in the teaching and learning of perimeter and areas. It is indicated in a study in I calculus teaching and learning at a higher institution by Naidoo (1998) that students have fundamental problems in understanding pre-concepts such as perimeter and areas which are taught in primary schools and that the Piagetian pre-formal and formal stages have not been developed. ti Primary school learners' first encounters with mathematics in a traditional learning environment often create lifelong 'math phobia' (Papert, 1980). The situation in a country I emerging from an oppressive education system designed to educationally disempower the I majority of the population is much worse. The typical scenario in a previously disadvantaged South African primary school is a classroom filled beyond capacity with the educator struggling to establish an effective learning environment. Thus the educator I resorts to rote learning, drill and practice and 'chalk and talk' methods of teaching. The I individual needs and levels of learners are disregarded and blanket assessment methods I are employed (Naidoo and Naidoo, 2006b). Collaborative learning is minimal or nonexistent. These traditional teaching strategies often disregard cultural and social factors, and pre-knowledge frames of learners. Furthermore there is a dire shortage of qualified mathematics educators in the South African schooling system. Therefore there is an urgent need for alternative teaching and learning strategies to address the teaching of mathematics in primary schools.

Esta investigación tiene como objetivo relacionar los factores de atributo y tipologías de liderazgo con apoyo informacional y emocional, eficacia colectiva y gestión institucional en directores de nivel primaria ante el manejo de situaciones de conflicto. El diseño es de enfoque cuantitativo, no experimental, transversal con alcance descriptivo, aplicando los instrumentos Escala de Eficacia Colectiva Docente para el Manejo de la Agresión entre Pares; Escala de Apoyo Directivo e inventario de prácticas de liderazgo, a 199 directores de Primarias del Estado de Sonora, México. El análisis de conglomerados con el método de K medias, mostró dos conglomerados, el primero nombrado “mayor capacidad de liderazgo”, integrado por 89 directores y el segundo “menor capacidad de liderazgo”, conformado por 110 directivos. Las correlaciones positivas más altas son 0.76 entre gestión institucional y eficacia colectiva docente, En la prueba T de Student para los factores de atributo, se obtiene diferencia estadísticamente significativa con el factor tipo de sostenimiento (público–privado) en la dimensión de la variable de liderazgo inspirar una visión compartida. Contrastando los conglomerados se obtienen diferencias significativas en apoyo emocional, gestión institucional y eficacia colectiva. Se discuten los resultados en términos de la importancia del liderazgo directivo para promover la gestión y eficacia colectiva docente concluyendo que cuando el directivo realiza prácticas de liderazgo y acciones de gestión institucional éstas impactan positivamente en la eficacia colectiva docente, a medida que el directivo inspira visión en su colectivo se asumen riesgos para modificar el curso de los acontecimientos desafiando el proceso.
Examination regarding the tolerability of the homochord Acidum L(+)-lacticum at a dosage of sixty drops three times daily
Authors: Sonntag Dieter
Published: August 2021

In Germany, the commission D recommends in its current dosage guidelines from March 17, 2004, that homeopathic dilutions higher than 24x will be prescribed in a daily application of five drops once. This recommendation is decisive for the German Regulatory Authority. Even though the homochord Acidum L(+)-lacticum 4x/6x/12x/30x/200x contains dilutions above 24x, it is commonly used in clinical practice for over 30 years in a dosage of 60 drops three times daily.

In order to explore the clinical safety and tolerability of Acidum L(+)-lacticum 4x/6x/12x/30x/200x at a dosage of 60 drops three times daily, as well as lower dosages, a therapist survey was designed to address the questions.

Highly experienced and licensed therapists, including general and alternative practitioners, reported their usual dosage of homochord, incidences of drug reactions, initial homeopathic aggravations as well as the diagnoses that led to the prescription of Acidum L(+)-lacticum 4x/6x/12x/30x/200x. 167 therapist responses were analyzed.

Only four therapists reported occurrences that classify as initial aggravation, (2.40 %), compared to 159 with no incidences (95.21 %). Four therapists made no statement. Nevertheless, there were no adverse drug reactions documented in the survey. Consequently, Acidum L(+)-lacticum 4x/6x/12x/30x/200x at a dosage of 60 drops three times daily or lower dosages may be construed to be clinically tolerable and safe. This evidence might lead to further re-evaluations of other homochords, and rigorous clinical trials for its safety and tolerability.

Published: August 2021

Em 2020, o mundo foi surpreendido pela pandemia de COVID-19, doença causada pelo coronavírus, que apresenta um espectro clínico variando de infecções respiratórias assintomáticas a quadros graves. Junto a pandemia, surgiu também a infodemia, caracterizada pelo excesso de informações, precisas ou não, que dificultam o acesso a fontes idôneas e orientações relevantes. Diante desse quadro, objetivo deste trabalho é um estudo teórico acerca da percepção da realidade na infodemia de COVID-19, especialmente na interpretação de desinformação. A expectativa é que a discussão identifique os aspectos mentais do indivíduo envolvidos no processamento da informação em excesso.
