Published: September 2020

The increase in motor vehicles accompanied with expansion of roads has brought with it the challenge of addressing the adverse influence of road traffic accidents. Road incidents are a nationwide cataclysm with ever increasing trend which incurs a human health and development challenge and highly affect the human capital development of every nation. A mortality rate database (WHO, 2002) assures that India has highest number of accidents. Accident Black Spots are those locations on the road which have higher severity of accident either in terms of numbers or in terms of injuries. In this paper, efforts have been made to identify the location of accident black spots on national highway from singhpora pattan to panthachowk srinagar.The present era accidents are contributing major deaths worldwide due to increase in vehicular traffic.It has been estimated that every year 1.38 lakh lose their limbs and 6 lakh people get injured in road accidents in india.our country incurs a loss of 58000 crore each year due to road accidents. The most used roads to travel from jalandhar in punjab to uri in kashmir is NH-1A.The old name for NH-44 is NH-1A which was replaced after renumbering of all national highways in year 2010. In this report,the analysis includes study of some major accident spots or busy intersections in the NH-1A in between Pantha chowkh Srinagar to Singhpora Pattan.The study includes visiting sites,collecting required data for analysis and derives the results and remedies from what we had got. This report will be containing the material surveyed,pictures of road at different locations ,road details,figures,material for understanding of the unknown and finally the conclusion

Racism and Discrimination: Let's practice what we preach
Authors: Modi Neena , Kumar Parveen , Rao Mala
Published: August 2020

With the world in turmoil,  an unexpected and tragic consequence of the SARS-CoV-2 pandemic has been its disproportionate impact on the British Asian and Minority Ethnic (BAME) communities. The pandemic led to an excessive number of deaths in these populations and revealed long-standing inequalities that began many years ago. This indictment raises questions about the extent to which racism and discrimination remain deeply rooted in British society.  Have the diverse groups that together constitute the rich fabric of British society not heard, or do they choose to be deaf and blind to the suffering caused by racism and discrimination?
A STATE-OF-THE-ART REVIEW OF TOURIST DECISION-MAKING LITERATURE
Authors: Vuong Thi Thao Binh , Nguyen Van Thang

Previous studies on responses of Foreign Direct Investment (FDI) firms to policy changes mainly focus on the impact of government policies on foreign investment flows in a country or in a province. So far, there has been no research on how Foreign Direct Investment enterprises, which are investing in Vietnam, react to unexpected changes in policies. We focus on studying some main factors affecting the behavior of FDI firms in Vietnam when the policy changes adversely. Using the data set of the annual Vietnam Provincial Competitiveness Index (PCI) survey with the foreign invested firms (FIFs) in Vietnam for 4 years from 2013 to 2016, the study shows that enterprises’ behaviors strongly depend on the capacity to predict changes in government policies. The policy changes directly affect business activities, so policymakers need to make a long-term stability plan to attract the FIFs. In addition, the FIFs tend to choose moving production to another country or coordinating with other businesses if local leaders are highly transparent. The opposite is true for the proactivity. In the case that local leaders are proactive, it helps FIFs feel secure to invest with enthusiastic support so the desire to move location or coordinate with other businesses is reduced. On the other hand, the FIFs are more likely to employ both formal and informal diplomacy if there is an increase in the number of employees, time spent interacting with government officers and prediction about policy change. Moreover, it is more likely to employ formal diplomacy than informal diplomacy in the case of FIFs’ size expanding. Similar to that case, it is true when increasing the capability of predicting harmful policy changes. We also find that the tendency of choosing formal diplomacy of foreign leaders is higher than that of Vietnamese leaders.
The impacts of consumer value and brand identification on brand loyalty and electronic word of mouth: the case of smartphone market in Ho Chi Minh City
Authors: Tran The Nam , Tieu Van Trang
Published: September 2020

Finding out the antecedents of brand loyalty is an interesting topic. The paper’s target is answering the question “Do consumer value and consumer-brand identification lead to consumer’s loyalty with the brand and positive electronic word of mouth in the context of smartphone market in Ho Chi Minh City?”. The authors used the PLS-SEM (Partial least squares structural equation modeling) to verify the relationship between independent variables and dependent variables using data collected from 320 smartphone users. The study shows that proposed antecedents have influences on dependent constructs. Such discoveries have both theoretical and practical implications. In theory, they support the theory of consumer value and the approach of brand identification. In practice, smartphone producers should provide gadgets with excellent performance and unique identity to keep consumers’ loyalty. As a result, companies will have active ambassadors for their brand.

The size of the dust torus in active galactic nuclei (AGNs) and their high-luminosity counterparts, quasars, can be inferred from the time delay between UV/optical accretion disk continuum variability and the response in the mid-infrared (MIR) torus emission. This dust reverberation mapping (RM) technique has been successfully applied to ∼70 z ≲ 0.3 AGNs and quasars. Here we present first results of our dust RM program for distant quasars covered in the Sloan Digital Sky Survey Stripe 82 region combining ∼20 yr ground-based optical light curves with 10 yr MIR light curves from the WISE satellite. We measure a high-fidelity lag between W1 band (3.4 μm) and g band for 587 quasars over 0.3 ≲ z ≲ 2 (

) and two orders of magnitude in quasar luminosity. They tightly follow (intrinsic scatter ∼0.17 dex in lag) the IR lag–luminosity relation observed for z < 0.3 AGNs, revealing a remarkable size–luminosity relation for the dust torus over more than four decades in AGN luminosity, with little dependence on additional quasar properties such as Eddington ratio and variability amplitude. This study motivates further investigations in the utility of dust RM for cosmology and strongly endorses a compelling science case for the combined 10 yr Vera C. Rubin Observatory Legacy Survey of Space and Time (optical) and 5 yr Nancy Grace Roman Space Telescope 2 μm light curves in a deep survey for low-redshift AGN dust RM with much lower luminosities and shorter, measurable IR lags. The compiled optical and MIR light curves for 7384 quasars in our parent sample are made public with this work.

Published: September 2020

In the present work, an experimental analysis was performed to obtain the calibration curve of three load cells connected in series. The control of the load applied on a given component is an important factor in some engineering applications, for example, in cases where it is desired to increase the heat exchange between two surfaces. One of the ways to control the applied load is the use of load cells, which has as its principle of use a strain gauge that has its resistance varied when it undergoes a deformation, thus causing a voltage variation due to the application of load. This study used an ArduinoTM microcontroller as a data acquisition system and blocks with known mass for load application.  In this way it was possible to obtain the calibration curve of the load cells by means of linear regression between the mass of the blocks and the data obtained by the ArduinoTM microcontroller and verify their applicability according to their measurement uncertainties.

Nos últimos anos, a crescente demanda por produtos naturais na indústria de alimentos incentivou esforços notáveis no desenvolvimento de processos biotecnológicos para a produção de compostos aromatizantes. O presente estudo relata a maximização da produção de acetato de isoamila por esterificação de álcool isoamílico e ácido acético em um sistema isento de solventes usando duas lipases diferentes como catalisador. A lipase Novozyme NZL-102-LYO-HQ (Candida antarctica B imobilizada em poliuretano – PU) foi comparada com a comercializada Novozym 435 e foi avaliada em termos de desempenho, rendimento e estabilidade operacional. Os efeitos nas taxas de reação mostraram valores maximizados diferentes, empregando esses dois catalisadores, no entanto as condições reacionais no que se refere a razão molar do substrato (ácido acético: álcool isoamílico), massa de catalisador e tempo de reação foram distintos. Embora Novozym 435 exibisse maior conversão inicial com relação a NZL-102-LYO-HQ, ambas formas lineares e apresentaram uma conversão superior a 90%. Para o catalisador Novozym 435 (razão molar 1:3 de ácido acético:álcool isoamílico e massa de catalisador 17% em peso) em 240 minutos e a Novozyme NZL-102-LYO-HQ (Candida antarctica B imobilizada em poliuretano – PU) (razão molar 1:5 de ácido acético:álcool isoamílico e massa de catalisador 7% em peso) em 360 minutos de reação com 10 ciclos de reutilização. Sendo assim esses resultados são de grande valia para a produção industrial, sobretudo na síntese de ésteres de cadeia média, como acetato de isoamila em diferentes preparações enzimáticas, tornando uma fonte promissora comparado com estudo apresentados na literatura aberta.

Published: September 2020

A rotulagem de produtos alimentícios é um importante elo entre o fabricante e o consumidor e representa o primeiro contato do consumidor com o produto. O rótulo tem por função fornecer diversas informações sobre os alimentos aos consumidores sendo estas informações determinadas por legislações específicas. Apesar da existência de resoluções sobre o assunto, ainda é observado o descumprimento das mesmas. Este trabalho teve por objetivo verificar a adequação da rotulagem de pães caseiros, pães integrais e biscoitos/ bolachas, comercializados em uma cidade do interior do Paraná, frente à legislação vigente. Foram analisados cinco rótulos de pães caseiros, cinco de pães integrais e nove de biscoitos/bolachas, totalizando dezenove produtos. Ao final do estudo, constatou-se que 94,74% dos rótulos analisados apresentaram no mínimo um tipo de não conformidade e, apenas 5,26%, estavam conformes com o estabelecido pela legislação brasileira vigente. Em relação ao tipo de irregularidades, a indicação do lote e da presença de alergênicos foram os itens que menos apareceram nos rótulos. Diante dos resultados encontrados fica evidente a falha dos produtores na elaboração dos rótulos de seus produtos e também dos órgãos fiscalizadores em permitir que tais produtos sejam comercializados sem atenderem as legislações vigentes.

Published: September 2020

Objetivou-se avaliar os efeitos do processamento sob a capacidade antioxidante de Tomate Seco Processado (TSP), por meio da comparação com Pasta de Tomate in natura (PT) e Tomate Seco Industrializado (TSI). As análises realizadas foram: carotenoides totais (CT), teor de antocianinas totais, polifenóis extraíveis totais (PET), atividade antioxidante total (DPPH) e capacidade antioxidante total (ABTS+).  Os dados obtidos foram avaliados quanto à correlação de Pearson. Observaram-se perdas de compostos bioativos nos tomates secos, exceto para antocianinas, onde TSP (3,04 mg.100 g-1) e TSI (2,67 mg.100 g-1) apresentaram teores estatisticamente superiores à PT in natura (1,65 mg.100 g-1), mostrando que o processamento promoveu a concentração das antocianinas. TSP e TSI forneceram acima de 100% da necessidade diária de licopeno total recomendada (8,06 e 10,96 mg/dia, respectivamente), na porção de consumo de 40 g, apresentando-se como alimentos ricos nesse carotenoide. Comparando-se os dois métodos de avaliação de atividade antioxidante total, pelo DPPH e pelo ABTS+, verificou-se que o TSP apresentou as melhores atividades antioxidantes (3379,93 EC50 em g.g-1 DPPH e 16,44 microM Trolox.g-1), em ambas as metodologias, em comparação a TSI e PT. A correlação de Pearson apontou que a atividade antioxidante dos produtos avaliados está mais relacionada à presença de carotenoides e antocianinas. O processamento térmico apresentou respostas variáveis na retenção e perda dos diferentes compostos bioativos, mas conferiu aumento da atividade antioxidante total. Os tomates secos apresentaram-se como produtos com alto teor de compostos antioxidantes, que podem substituir o tomate in natura, além de ser uma rica fonte de licopeno.

Published: September 2020

A COVID-19 gerou crise mundial na saúde pública e na economia, mas muitas universidades se engajaram para minimizar impactos negativos na sociedade. O projeto ‘Atentar-se à Exclusão para Contribuir com a Inclusão’, da UTFPR, propôs ação emergencial para enfrentamento da pandemia. A ação envolve esforços colaborativos de extensionistas para assessorar e empoderar catadores de materiais recicláveis na obtenção de auxílios emergenciais. A abordagem concatena pesquisa sobre saúde ocupacional, levantamentos de necessidades das famílias dos catadores, definição de estratégia da campanha 'Catadores em Quarentena' e avaliação da ação. A iniciativa prossegue com cadastramento para auxílios governamentais, entrega de alimentos, medicamentos e produtos de higiene e limpeza. Este artigo descreve que as ações não se encerram em caráter assistencialista, mas exigem responsabilidade social e cívica na valorização do trabalho dos catadores de materiais recicláveis, durante e após a pandemia.
A guild classification system proposed for anuran advertisement calls

Published: September 2020

Zoologists have widely acknowledged the utility of classification systems for characterising variation in anuran egg and clutch types, tadpole morphotypes, embryonic and tadpole development, amplexus types and reproductive modes. These classification systems have facilitated unambiguous communication between researchers, often working in completely different fields (e.g. taxonomy, ecology, behaviour), as well as comparisons among studies. A syntactic system, classifying anuran call guilds, is so far lacking. Based on examination of the calls of 1253 anuran species we present a simple, easy to use dichotomous key and guild system for classifying anuran advertisement calls – the call type most frequently emitted by anurans and studied by researchers. The use of only three call elements, namely clearly-defined calls, notes, and pulses, plus presence or absence of frequency modulation, allows assigning all currently known anuran advertisement calls to one of eight distinct call guilds defined here. This novel toolkit will facilitate comparative studies across the many thousand anuran species, and may help to unravel drivers of anuran call evolution, and to identify ecological patterns at the level of acoustic communities.
La coexistence de l’amour romantique et du confluent en Espagne
Authors: Roche Cárcel Juan A.
Published: September 2020

À de rares exceptions près dans son histoire, la sociologie a négligé l’étude de l’amour jusqu’à l’apparition, en 1982, de l’ouvrage de N. Luhmann sur L´amour passion . Depuis lors sont apparus de nombreux travaux, théoriques et empiriques, ainsi que d’importantes monographies sur ce sujet. Cette problématique des émotions amoureuses a pu ainsi prendre une place centrale dans notre discipline. En suivant, précisément, les lignes tracées par la sociologie, et à partir de quelques-uns des travaux sociologiques les plus récents qui ont analysé l’amour dans la société espagnole, j’essaie de montrer comment ils y sont institutionnalisés, formalisés ou « familiarisés » ; des manières modernes d’aimer, c’est-à-dire romantiques et confluentes ; comment ces deux types d’amour coexistent et comment ils le font ; quels sont leurs degrés de priorité première et secondaire ; enfin, j’essaierai d’expliquer, à travers les différentes visions de l’amour romantique et de l’amour confluent, les causes de cette situation. Comme nous le verrons, les deux manières modernes d’aimer sont présentes et coexistent actuellement dans la société espagnole : l’amour romantique est encore majoritaire, alors que l’amour confluent progresse sans pour autant s’institutionnaliser, selon les différentes conceptions du temps sous-jacentes à ces deux formes d’amour.

In this paper, we will investigate some properties for almost cellular algebras. We compare the almost cellular algebras with quasi-hereditary algebras, which are known to carry any homological and categorical structures. We prove that any almost cellular algebra is the iterated inflation and obtain some sufficient and necessary conditions for an almost cellular algebra $ \mathrm{A} $ to be quasi-hereditary.
Incentive contract design for supplier switching with considering learning effect
Authors: Wei Qian , Zhang Jianxiong , Sun Xiaojie
Published: September 2020

For minimizing purchase cost, a buying firm would switch to suppliers with providing more favorable prices. This paper investigates the optimal switching decision of a buyer that may switch to an entrant supplier with production learning ability (which is regarded as a private information) under a principal-agent framework. The results obtained show that the switching cost and the learning effect have significant impacts on the buyer's switching decision. Only when the fixed component of the switching cost is relatively low, the buyer can be better off from a partial switching strategy; otherwise, the buyer should take an all-or-nothing switching strategy or no switching strategy. As the learning ability of the entrant supplier increases, the buyer prefers to make more switching. Finally, a benefit-sharing contract is proposed to evaluate the performance of the principal-agent contract, and we demonstrate that the principal-agent contract almost completely dominates the benefit-sharing contract.
A Bayesian Approach to Supervisory Risk Control of AUVs Applied to Under-Ice Operations

Published: August 2020

AbstractAutonomous underwater vehicles (AUVs) are efficient sensor-carrying platforms for mapping and monitoring undersea ice. However, under-ice operations impose demanding requirements to the system, as it must deal with uncertain and unstructured environments, harsh environmental
conditions, and reduced capabilities of the navigational sensors. This paper proposes a Bayesian approach to supervisory risk control, with the objective of providing risk management capabilities to the control system. First, an altitude guidance law for following a contour of an ice surface
via pitch control using measurements from a Doppler velocity log (DVL) is proposed. Furthermore, a Bayesian network (BN) for probabilistic reasoning over the current state of risk during the operation is developed. This is then extended to a decision network (DN) for autonomously adapting
the behavior of the AUV in order to maximize the mission utility, subject to a constraint on the predicted risk from the risk model. The vehicle is thus able to autonomously adapt its behavior in response to its current belief about the risk. The goal of this work is to improve the AUV performance
and likelihood of mission success. Results from a simulation study are presented in order to demonstrate the performance of the proposed method.
Vaginal Cuff Dehiscence with Small-Bowel Evisceration Following Total Laparoscopic Hysterectomy – An Unusual Case
Authors: Thakur Vaidehi D. , Paprikar Manoj M , Singh SM
Published: September 2020

Small bowel evisceration from dehiscent vaginal cuff is unusual subsequent to laparoscopic hysterectomy. This complication is seldom cited in studies and reviews. We present an uncommon case of evisceration of small bowel from vaginal cuff dehiscence (VCD). The event occurred approximately 2 hours subsequent to the first act of coitus performed 3 months after the laparoscopic hysterectomy. Patient was brought to the emergency department for primary treatment. Urgent surgical intervention was planned. Small intestine was reposed after saline wash. Repairing of the vault was done with continuous suture by polyglactin-910 braided synthetic absorbable suture no.1. Patient was sent to home after 5 days of surgery. The strength of vaginal vault in laparoscopic hysterectomy depends on technique of vaginal cuff closure and types of suture materials used during surgery. Postoperative counseling of patients for recommencing physical activity and sexual intercourse is also of utmost significance.
Fostering posterity and socio-economic transformation through the prism of indigenous languages in youth training: A participatory approach
Authors: Mavesera M. , Magege D.
Published: September 2020

This paper reviews thee mediating role of indigenous languages in vocational skills and national development in the Zimbabwean context. In the wake of the current outcry for jobs, employment creation and entrepreneurship the need for new strategies to revive industry by focusing on community resources has become imperative. Youths need to turn to themselves as repositories of skills required for operationalising dormant and fledgling industries. In pursuit of this new strategy they need the expertise of local artisans. The initiative, adopted in the spirit of national consciousness, should yield an indigenous brand of technology. It is from this perspective that the paper argues for a fresh, broader approach to youth training, through the identification of a national programme that encourages skilled artisans to use indigenous languages as vehicles for imparting industrial skills to out of school youths. The envisaged formal programme can be implemented through the identification of industrial bases that would tap the industrial skills of out of school youths, under the tutorship of local skilled artisans. For more effective implementation the proposed blueprint argues for the liberalization of instructional media. Trainers and trainees would switch on to their preferred language in skills’ acquisition. Such a flexible project, sustained through collaborative engagement, between skilled artisans and youths, would go a long way towards enhancing the latter’s creative potential, by fostering familiarity with the terminology required by a particular industry. Further, the article envisages learners’ progressive training programmes that motivate vocational training graduates to apply modern technology to productive processes demanded by the respective communities. The study concludes by emphasizing that the achievement of national goals for entrepreneurship and youth empowerment/employment requires the adoption of new strategies encapsulated in the Education 5.0.blueprint.

“In Our House We Speak Polish”
Authors: Borowczyk Margaret
Published: September 2020

This study explores the ways the value of Polish is framed in a promotional campaign for Polish heritage language education (HLE), and how heteroglossia (Bakhtin, 1981) functions within campaign interviews to construct alternative visions for the future of Polish HLE. In communities where knowledge of the HL cannot easily be credentialed or monetized, and where increasing demographic diversity demands to be acknowledged, neoliberal and essentialist arguments for learning the HL often seem incomplete and insufficient. Counting Polish among these languages, I explore how advocates of Polish HLE frame the ways in which Polish can serve as a resource for heritage speakers, identify important absences in this discourse, and then discuss how centripetal and centrifugal discourses (Bakhtin, 1981) vie for primacy in their arguments. I conclude by critically examining the ideologies that contribute to this promotional strategy and suggest future avenues for promotion that move beyond pitches about the global economy and essentialist
identity, by centering locality and hybridity
Effect of pH, Anions and Acids on the Extraction of Zinc (II) from Aqueous media using Acetylacetone Solutions of Sulphamethoxazole

Published: August 2020

The challenge of heavy metal contaminations have been remediated to a certain level by the application of several methods of their extractions from aqueous media. Solvent extraction of zinc (II) ions from buffered aqueous solutions into acetylacetone solution of sulphamethoxazole as a function of pH and concentration of anionic substances and certain mineral acids were investigated in this work. The aqueous medium was prepared by dissolving 1.0995g of ZnSO4.7H2O in 250 ml volumetric flask to form 1000mg/L solution. 50mg/L working concentration was prepared from the 1000mg/L by dilution method. The organic phase is 0.5 M Sulfamethoxazole solution prepared by dissolving 12.664g of the salt in 100 ml acetylacetone. 2 ml each of aqueous and organic phases were taken with micro pipette and transferred into a set of 20 ml extraction bottle and the mixture was agitated mechanically for about 30 minutes. The mixture was allowed to settle and separate into two layers. 1 ml of the aqueous phase was taken, diluted and analysed for Zn (II) ions using atomic absorption spectrophotometer at a wavelength of 213.9. The results obtained on studying the effect of pH showed that Zn (II) ion was quantitatively extracted between pH of 7.0 to pH 8.0. The highest percentage extraction 85.37% was observed at pH 8.0 in acetylacetone solution of sulphamethoxazole. Increase in pH above 8.0 resulted in a steady decrease in the extraction of Zn (II). Studies on the effect of anions showed significant extractions which changes as the anions concentrations increased. All studies on mineral acids also showed significant extractions and increase in the concentrations of the acids affected the percentage extraction. Generally Zinc (II) ions can be extracted quantitatively in mild acids and anions concentrations when buffered from slightly acidic pH ranges of 6.0 to slightly alkaline pH values of 8.5.
Petroleum Potential of Gombe Formation, Kolmani River-1 Well Gongola Basin, NE Nigeria

Published: August 2020

Gombe Formation is one of the promising potential source-rock of petroleum in the Gongola basin based on its appreciable amount of organic matter. The present study is therefore aimed at evaluating the hydrocarbon potential of Gombe Formation. Ditch-cutting samples were collected from the depth of 731.5 m to 1554.5 m from Gombe Formation that penetrated the Kolmani River-1 well. The source-rock potential was evaluated based on kerogen analysis and soluble organic matter content using Fourier Transform- Infra red spectroscopic (FT-IR) and Gas chromatography-Mass spectrometric (GC-MS) techniques respectively. There is presence of peak at 900-1000 cm-1 which is due to CH2 rocking vibration in long chain aliphatic substances, which is characteristic of liptinite macerals indicating good potential source-rock for oil and gas. The n-alkane ranges from C11-C33 maximizing at nC16 which suggests that the organic matter are majorly derived from marine organic matter. The Pr/Ph (1.49-1.92) shows that the organic matter was deposited under sub-oxic condition. The distribution of hopanes, homohopanes (C27-C29) steranes, (C0-C4) alkylated naphthalenes and (C0-C3) alkylated phenanthrenes indicate the presence of angiosperm, gymnosperm, algae, marine and bacteria input to the organic matter contained in the samples. Also the plot of DBT/P vs. Pr/Ph classifies the samples into zone 3 (i.e. marine shale and other lacustrine). Various maturity parameters computed from saturate biomarker and polycyclic aromatic hydrocarbon distributions shows that the samples are low mature with the moderately mature zone at the bottom (>1408.2 m) of Gombe Formation. In conclusion, the kerogen was probably derived from type II/III organic matter capable of generating both oil and gas and the moderately mature zone lies at the bottom of the Formation. Key words: Lacustrine, Gombe formation, Maturity, Hydrocarbon, Kerogen

The Gas Chromatography– Flame lonization Detector (GC-FID) method was employed in this study to evaluate the phytochemical constituents of both the aqueous and petroleum ether extracts of phyllanthus amarus leaves. Preliminary phytochemical screening showed the presence of Alkaloids, Flavonoids Glycosides, Phenols, Saponins, and Tannins. Further analysis revealed a total concentration of Phenol as 82.95mg/100g (4.46%) in the aqueous extract, Tannins 722.77mg/100g(38.82%),Alkaloids was 466.82mg/100(25.07%) while in the petroleum ether extract, Flavonoids was 472.59mg/100g (29.50%), Saponins 12.60mg/100g (0.79%) and Glycosides 18.63mg/100g (1.16%). These results are suggestive that P.amarus is endowed with phytochemicals that contains therapeutic potencies which support its use as traditional remedies for the treatment of variety of ailments.

Hydrogeophysical investigation of groundwater systems in Otukpo, Benue State, Nigeria has been carried out using vertical electrical sounding (VES) technique to delineate the groundwater potentials across the study area. Ten (10) vertical electrical soundings were carried out during the geophysical survey using the Schlumberger configuration of electrical resistivity method with maximum current and potential electrode spacing of 600 meters and 80 meters respectively. The VES data was qualitatively and quantitatively interpreted using the conventional curve matching and computer iteration methods. The result of qualitative interpretation depicts that the VES curves obtained within the study area are mainly the QH and KQH which are typically indicative of a sedimentary terrain. The results of the quantitative interpretation reveal that the resistivity values from shallow subsurface to the depth of about 500 m of the VES stations ranges from 3 Ωm to 1250 Ωm. The VES results also show that the study is characterized by seven (7) different inferred lithological layers namely; topsoil, sand/silt, laterite, clay, shale, sandstone and the basement rock. The result also reveals that the depth to water-saturated unit ranges from 450 to 500 meters within the study area. Two distinguished aquifer types were obtained within the area namely; unconfined and confined aquifers. The findings reveal that the future borehole drillers should target the confined aquifers situated between the depths of 450meters to 500 meters beneath the surface for sustainable groundwater yield across the study area.

In order to assess the potability and agricultural application of Mini-Whuo stream in Eliozu Port Harcourt, Rivers State, Nigeria; the physicochemical properties, heavy metal levels (Fe, Cr, Cd, Pb & Ni) and microbiological load of water were evaluated. Five stations were established and sampling made for a period of six months (May-October 2019). Various water samples were collected for the analysis of physicochemical properties, heavy metal and microbiological levels, using titrimetric, spectrophotometric and microbiological methods respectively. Results obtained from the analyses showed that, temperature ranged between (28.7±0.7-30.9±1.9ºC), pH (6.4±0.0-6.7±0.3), electrical conductivity (82±20-172.0±14 µS/cm), total dissolved solids (41±1-86.5±71.1mg/l), turbidity (8.1±1.6-18.1±2.8 NTU), chloride (5.60±1.63-7.76±0.96 mg/l). Levels of heavy metals analyzed for water were below detection limit of 0.01mg/l, except for Fe which ranged between (3±1-4.6±0.8 mg/l). Microbiological study of water showed that the water had (2.6±0.5-6.4±0.6 x103 cfu/MLN) count of total heterotrophic bacteria, (44.3±9- 323.8±44 MPN/100ml-1) count of total coliform bacteria count and (4.3±2.7-59.5±16.9 MPN/100ml-1) faecal coliform bacteria count. From the result of analyses it was observed that iron, dissolved oxygen, electrical conductivity, total dissolved solids, and the microbiological load of the water were high when compared with WHO standards, and this may be attributed to the disposal of wastes such as, human and animal wastes into the water body. Water quality index (WQI) method according to the weighted arithmetic WQI, where (WQI < 50 = excellent water quality), (50 > WQI < 100 = good water quality), (100 > WQI < 200 = poor water quality), (200 > WQI < 300 = very poor water quality), and (WQI > 300 = unfit for drinking). Based on the WQI calculated for the Mini-Whuo stream 1156, the stream is not suitable for domestic use.

The functional properties are the intrinsic physicochemical characteristics which affect the behavior of ingredient in food systems during processing, manufacturing, storage and preparation etc. Such functional properties include water and oil binding, emulsification capacities, swelling ability and viscosity. This work is aimed at evaluating the swelling Ability and water binding capacities of Spinous Amarantus (alayahon daji) (AA) Senna accedentalis (tasba) (TB), Phyllantus niruri (mace mai goyo) (MC), Hibiscus sabdrariffa (yakuwan daji) (YD) and Leptadenia hastate (yadiya) (YE) which are commonly consumed in our localities with little or no knowledge about their nutritional properties. AOAC method of analysis as outlined by Adabowale was adopted for the analysis with little modifications. All the samples analyzed showed significant water swelling ability with AA and YD showing the highest values of 1.5±0.06 v/g while TB shows the lowest value of 0.5±0.05 v/g. There was a significant difference (p <0.05) in the WBC values (%) obtained for the different plants analyzed. The results revealed that crude AA has the highest value of 12.48±0.82 and YD has the lowest value of 5.50±0.09. Insoluble dietary fiber (IDF) was also extracted from the samples and evaluated for water binding capacity. The Insoluble dietary fibre (IDF) showed WBC values. The highest values 1.54±0.08g/g and lowest 0.94±0.00g/g were obtained MC and YE respectively. All the crude samples showed significant water binding capacity (WBC) than their respective insoluble dietary fiber (IDF). This is as a result of the structural and chemical composition of the crude samples. However, the research has revealed that both the crude and the IDF samples analyzed has therapeutic potentials.

O processo cultural deve exercer o papel social, mediando à sociabilidade e preparando o homem para a aplicação do conhecimento por meio do exercício da atividade transformadora da natureza.
Institutional philanthropy and popular organising in Africa : some initial reflections from social movement activists
Authors: Mahomed Halima
Published: September 2020

As popular forms of organising increasingly serve as sites for change in Africa, institutionalised private philanthropy, which has generally stayed away from such activist spaces is slowly engaging. While anecdotal knowledge exists, evidence-based analysis on these relationships is scarce. This study explored how African movements experience and see the role and nature of philanthropy in relation to their own functioning and objectives. It highlighted that it is not merely a question of whether it is appropriate for institutional philanthropy to engage, but the ‘how’ of engagement that matters most. As a result, different challenges and limitations emerged. The research reflected critical concerns raised by movements about philanthropic orientation, ideology, and practice, and called for radical mindset shifts from institutional philanthropy – particularly on aspects such as power, control, accountability, and impact – and provided practical observations for consideration.

Familial non-medullary thyroid cancer (FNMTC) comprises about 5-15% of non-medullary thyroid cancer (NMTC) is a heterogeneous of diseases including both non-syndromic and syndrom forms , Non-syndromic FNMTC tends to manifest paillary thyroid carcinoma,usually multifocal and bilateral.Several high-penetrance genes for FNMTC have been indentified but they are often confined to a few or single families and other susceptibility loci appear to play a small part ,conferring only small increments in risk . Familial susceptibility is like to be due to a combination of genetic and environmental influences . The current focus of research in FNMTC is to charactetise the susceptibility genes and their role in carcinogenesis .FNMTC can also occur as a part of multitumor genetic syndromes such as familial adenomatous polyposis ,Cowden’s syndrome, Werner’s sydrome and Carney complex . There tend to present at an early age and are multicentric and bilateral with distinct pathology . The clinical evaluaion of these patients is similar to that for most patients with a thyroid nodule.
