Authors: Fajinmi Olufunke O. , Olarewaju Olaoluwa O. , Arthur Georgina D. , Naidoo Kuben , Coopoosamy Roger M.
Published: June 2022

Background: Food and nutritional security are main development goals in several countries of Africa. In West Africa, the use of African indigenous vegetables caters for the food and nutritional needs of a high proportion of the people, most particularly amongst the poor and rural dwellers. The family Cucurbitaceae is one of the most important and widely grown vegetables in the tropical and subtropical climates.Aim and objective: This review discusses the culinary relevance of several species of Cucurbitaceae and their roles in food security in West Africa.Methods: A literature search was conducted on electronic databases such as Google Books, Google Scholar, Scopus and Web of Science.Discussions: Certain genera such as Telfairia, Cucurbita and Citrullus and other Egusi species are commonly cultivated in different parts of West Africa including Nigeria for their fruits, seeds and leaves because of their crucial nutrient compositions and palatability in local diets. These species and other species of Cucurbitaceae are used as traditional vegetables or African indigenous vegetables and are either sourced from the wild or cultivated in several African countries. Some of these species have played roles beyond food security but have also been crucial tools for nutritional security, especially within the low-income group and rural communities.Conclusions: Several communities in West Africa use almost all parts of the plant (leaves, fruit, seed, flowers) of some species of this family as food or in food preparations. Their use could also lead to innovative pathways towards reducing diseases associated with malnutrition especially those related to protein deficiency.
How Balinese Hindus interpret the story adapted from the story of the Syrophoenician woman found in the Christian Bible in Mark 7:24–30
Authors: Hauw Andreas , Okvitawanli Ayu , Sari Betty T.
Published: June 2022

This article proposes an alternate way of reading the story of the Syrophoenician woman found in the Christian Bible in Mark 7:24–30. The goal of this contextual reading is to see how cultural and ethnic identity affects the perception of the story and the level of reverence to Jesus in the story. In this study, a non-Christian population was selected to avoid pre-conceived notions of the well-known story. The sample in this study comprised a Balinese student population (90.3% Hindu and 40.3% men). The results show that ethnic identity relates positively to positive perception of the Syrophoenician woman. When forced to choose between siding with the woman or with Jesus (labelled as ‘religious leader’), the perception of the good character of the woman relates to her being chosen as the hero of the story; however, her submissive attitude relates negatively to her being chosen as the hero of the story.Intradisciplinary and/or interdisciplinary implications: This article takes a cultural psychology and narrative approach to evaluate the behaviour and perceptions of Balinese Hindus in seeing the roles of women and religious teachers. The general perception and behaviour in religion seems to be influenced by the sociocultural context. Interdisciplinary implications of theological and psychological study are confirmed in the article.
Acoustic-Fluid-Structure Interaction (AFSI) in the Car Underbody
Authors: Schwertfirm Florian , Hartmann Michael
Published: June 2022

The turbulent flow around vehicles causes high amplitude pressure fluctuations at the underbody, consisting of both hydromechanic and acoustic contributions. This induces vibrations in the underbody structures, which in turn may lead to sound transmission into the passenger compartment, especially at low frequencies. To study these phenomena we present a run time fully coupled acoustic-fluid-structure interaction framework expanding a validated hybrid CFD-CAA solver. The excited and vibrating underbody is resembled by an aluminium plate in the underbody of the SAE body which allows for sound transmission into the interior.

Different excitation situations are generated by placing obstacles at the underbody upstream of the aluminium plate. For this setup we carry out a fully coupled simulation of flow, acoustics and vibration of the plate. The simulation results are compared and validated with experimental results of surface microphones, acceleration measurements and sound spectra of the interior. The analysis of the results focuses on the ratio of hydromechanic and acoustic excitation in frequency space and on possible back coupling effects of the structural vibration on the results. In the outlook, one example of an application of this method in the vehicle development is given.
Model Based Design, Prototyping and Testing of a Small Size High Speed Electrically Driven Centrifugal Pump

Published: June 2022

Within automotive sector, there are several high-performance applications, like, for instance, those referred to racing and motorsport, where cooling needs are usually fulfilled by simple circuits with conventional low-efficiency pumps. The cooling needs in these applications are represented by low flow rates delivered (in the range of 10 - 50 L/min). The operating conditions of these small pumps are usually characterized by very high revolution speeds, which intrinsically cause low efficiency and critical intake phenomena (cavitation) if the design is not specifically optimized to address these concerns.

Hence, in this paper a small-size pump operating in the racing sector has been designed using a model-based approach, built and tested having reached both high efficiency (aimed to 50%) and absence of intake operational problems (cavitation). Starting from the specific cooling request (design flow rate equal to 14.0 L/min and pressure rise equal to 2.5 bar), the very limited space available on board oriented the design to an operational revolution speed of 12000 RPM. The interest of this study was to introduce a so high revolution speed in more conventional automotive cooling pumps electrically assisted, keeping high efficiency. In fact, the strong reduction of the size of the pump allows an easy and correct positioning on board.

The model-based design was done by a two-steps procedure. The first made use of a 0D model which, catching main physical phenomena of the flow even in simplified form, leads to an optimum geometrical design for the impeller and the volute. A final refinement has been done with a CFD code predicting the off-design performance and limiting cavitation zones. Cavitation, which is one of the most critical issues of high-speed pumps, was completely investigated through a CFD numerical analysis.

The pump has been prototyped and tested on a dynamic test bench for pumps, which reproduces homologation cycles and real driving. A good agreement has been reached between theoretical and experimental results, being the mean relative error on pressure rise for all operating point close to 4 %. This model-based procedure opens the way to support the development of electric water pumps for more conventional applications (automotive, light duty engines) in which a redesign will be focused to manage the thermal state of the engine and reduce the energy absorbed during the homologation cycle.
Design of the In-vehicle Experience
Authors:   fka SV Inc, Roth Christian
Published: June 2022

The in-vehicle experience, both physical and digital, is increasingly the differentiating factor between vehicles. Since touch displays, smart surfaces, and internet connectivity are present in most vehicle segments, the growing resemblance of in-vehicle experiences with mobile experiences leads to user expectations on par with smartphones. While manufacturers are faced with providing suitable service offerings that are safe to use, they must also identify services to exclude or limit, without encouraging drivers to resort back to their mobile devices. This increasingly complex in-vehicle experience design process is being shaped by new stakeholders, including operating system providers and application developers. Design of the In-vehicle Experience examines the challenging and changing relationships between manufacturers (that lack in software development and mobile experience design skills) and new stakeholders (that lack the decades of experience designing for the driving context). The report also discusses augmenting and expanding existing guidelines and best practices to address the challenges of modern in-vehicle experience design.

Au sahel, le déséquilibre entre les besoins des populations et la capacité de production des écosystèmes entrainent un amenuisement des ressources forestières consécutif à une baisse du niveau de vie des populations. Toutefois, la connaissance du niveau de résilience des communautés et des écosystèmes comme les aires protégées permettra d’atténuer les impacts. Cette étude vise à évaluer la phytodiversité des unités d’occupations de la forêt classée de Gorou Bassounga et à apprécier la perception paysanne du changement climatique. Une cartographie de la forêt a été réalisée avec des images sentinel suivis d’un inventaire floristique dans 59 relevés issus d’un échantillonnage stratifié aléatoire et des enquêtes auprès des groupes ethnolinguistiques. La carte d’occupation a fait ressortir six unités à savoir savane arbustive, forêt galerie, sol nu, champ-jachère, formation contractée et affleurement rocheux. Trois groupements végétaux ont été identifiés avec une flore constituée de 95 espèces et une diversité de Shannon élevée. Cependant, la qualité des parcours pastoraux est menacée par l’abondance de Hyptis suaveolens. Par ailleurs, les paysans perçoivent le changement climatique à travers la baisse des pluies, la perte de la biodiversité et l’exode des populations. Ces résultats sont des outils qui serviront pour une meilleure gestion de la forêt.

Published: June 2022

Jatropha curcas L. est une plante arbustive de la famille des Euphorbiaceae qui a la capacité de croître en s’adaptant à divers environnements. Cette étude visait à apprécier son développement lorsqu’il est conduit sur un sol surexploité. Spécifiquement, il s’agit de tester le type de matériel végétal, l’écartement de semis et les délais sur quelques paramètres morphométriques de cette espèce. Le modèle linéaire à effet mixte et le modèle linéaire généralisé ont été utilisés sous le logiciel R pour évaluer les performances de croissance du pourghère. Les analyses statistiques ont permis de comparer les moyennes. Les résultats révèlent que la croissance en hauteur des plantes de Jatropha est influencée de manière très significative (P <0.001) par l’interaction du type de matériel végétal et de l’écartement de semis et que la croissance du diamètre au collet s’accroit avec le temps tout le long de l’année. L’émission des feuilles s’est accrue pendant les trois premiers mois, puis il y a eu une chute continue le reste du temps quel que soit l’écartement et le type de matériel végétal. Au regard des résultats obtenus, il ressort que Jatropha curcas développe plusieurs mécanismes pour s’adapter et croître sur un sol surexploité.

Published: June 2022

Maerua angolensis is a shrub/small tree that grows up to about 10 m tall. The plant is widely distributed in tropical Africa and used in various ethnomedicinal applications across the region. The objective of this study is to investigate the oral safety profile of the infusion extract of Maerua angolensis (IEMa) in laboratory animals. Hippocratic screening was adopted to evaluate the acute toxicity profile using 2000 mg/kg of IEMa, p.o. in mice. The sub-chronic toxicity was performed by daily oral administration of IEMa (800 mg/kg) in Wistar rats for 28 days and clinical observations and toxicological related parameters were recorded. After the treatment period, blood was collected for hematological and biochemical analysis, and organs were removed for macroscopic analysis. The agent exhibited mild symptoms and no mortality recorded in the Hippocratic screening. In the sub-chronic test, few changes in urine output, platelets counts and alkaline phosphatase were observed, but are within the physiological ranges for this animal specie. The results shows that IEMa does not present oral toxicity thereby displaying a wide safety margin for therapeutic use.

Au Niger, le Gombo représente l’une des plus importantes cultures maraichères. L’objectif de cette étude était d’évaluer l’impact de cinq types de fertilisants sur la productivité de trois variétés du gombo de la région de Zinder. L’étude a été conduite pendant la campagne agricole 2020-2021 en deux essais repartis sur deux périodes : la première pendant la saison de pluie (Juillet à Octobre 2020) et la deuxième en saison sèche froide (octobre 2020 à Janvier2021). Le dispositif adopté est un split-plot avec trois répétions et cinq traitements de fertilisants dont deux types de composts (Fumier de bovin et Fiente de volaille bien décomposés), deux fertilisants minéraux (NPK et Urée) et un témoin qui consistait à aucun apport de fertilisants. Les données collectées à travers 15 caractères agronomiques et morphologiques du gombo ont été analysées avec le logiciel XLSTAT version d’essai 2021. Il résulte de cette étude que les fertilisants ont eu des impacts sur la productivité des variétés du gombo. La meilleure production en biomasse et en fruits a été obtenue avec la Fiente de volaille suivie de NPK et Compost pour toutes les variétés étudiées. En effet, la fiente de volaille a augmenté de plus 70% le poids des fruits chez la variété longue. Donc la fiente de volaille et le compost pourraient constituer une bonne alternative aux engrais minéraux.

L’insémination artificielle sur oestrus induit constitue une alternative intéressante pour améliorer la production laitière bovine et de contourner aux problèmes de détection de chaleur naturelle. L’objectif de cette étude était de déterminer l’efficacité des traitements d’induction d’oestrus à base de spirale Delta associé à la prostaglandine (PGF2α) et à l’équine chorionic gonadotropin (eCG) et la fertilité après IA dans les élevages de zébu de la zone péri-urbaine de Ouagadougou. L’expérimentation a concerné 156 femelles zébus regroupant des nullipares (n=77) et des multipares (n=79). Elles ont été soumises à un protocole d’induction d’oestrus à base de spirale vaginale Prid® Delta imprégnée de 1,55 ml de progestérone. La pose de la spirale correspondait à la date J0 et suivie d’une Injection Intramusculaire (IM) de 5 ml de PGF2α (enzaproste) au 8ème jour et de 5 ml (en IM) d’eCG au 10ème jour. Le retrait de la spirale est intervenu à J10. Tous les animaux ont été inséminés systématiquement 48 h après l’arrêt du traitement. Le diagnostic de gestation a été réalisé à 60 jours plus tard après l’insémination artificielle par palpation transrectale (PTR). Les taux d’induction et de fertilité ont été respectivement de 100% et de 61,59%. Les paramètres tels que la race, le poids et la parité ont influencé significativement (p ≤ 0,05) la fertilité à l’IA. Le taux de gestation a été de 61,33% pour les Métis, 58,33% pour les zébus Peulh et 42,10% pour les zébus Goudali. Les animaux de poids excédant 300 kg ont donné un taux de gestation de 60,60% contre 44,89% pour les animaux de poids inférieur à 300 kg. Un taux de gestation de 64,51% a été obtenu chez les vaches de parité 2 et 3 contre 74,07% chez celles de parité ≥ 4. L’application du protocole à base de spirale vaginale Prid® Delta associé à la PGF2α et à l’eCG dans les élevages bovins de la zone péri-urbaine de Ouagadougou a été efficace pour l’induction d’oestrus et l’IA. Par ailleurs, il est envisageable avec l’échographie, de suivre l’évolution folliculaire pour déterminer les dates et les qualités des ovulations afin de mieux ajuster les interventions.

Anthocyanins are bioactive compounds which, due to their free radical scavenging properties, can protect the human body against oxidative stress that can cause many diseases, such as cancer, aging. The Tuskegee purple Cap Vert and Tuskegee purple sweet potato (Ipomoea batatas L.) varieties are rich in anthocyanins. Indeed, their total anthocyanin contents are estimated at 0.211 and 0.122 mg/g of fresh plant material, respectively. And the antiradical activities of the varieties Tuskegee purple and Tuskegee purple Cap Vert extracts were estimated at 0.06 and 0.05 mg/mL respectively. The identification of anthocyanins in the extracts of the two sweet potato varieties was performed by HPLC-MS-UV, and HPLC-MS/MS analyses. Four anthocyanin isomers were identified in Tuskegee purple Cap Vert variety. These are : cyanidin 3-sophoroside-5-glucoside ; peonidin 3-sophoroside-5-glucoside ; cyanidin 3-laminaribioside-5-glucoside ; peonidin 3- laminaribioside-5-glucoside.

Ces dernières années, le bassin versant de Didagou à Dapaong a été transformé en dépotoir par les populations, occasionnant la pollution du barrage de Kalsom qui approvisionne la ville en eau potable. Cette étude avait pour objectif de faire l’état des lieux de la pollution des ressources en eau du bassin. L’évaluation de la qualité physicochimique et bactériologique a été réalisée sur 26 échantillons en janvier et Octobre 2019 en utilisant les méthodes normalisées de l’Association Française de Normalisation. Les résultats ont révélé qu’en saison pluvieuse, tous les échantillons analysés ont été pollués par au moins un germe indicateur de pollution fécale. Les puits traditionnels étaient plus contaminés (92% de non-conformité). Dans la même saison les concentrations en nitrates, nitrites et phosphores étaient à la hausse. Aussi, les facteurs de concentration des éléments traces métalliques par rapport à la valeur guide OMS dans les échantillons prélevés allaient de 1,6 à 2,5 pour le Mercure ; de 1,13 à 2,3 pour le Cadmium ; de 1,18 à 6 pour le plomb et de 2,3 à 6,7 pour l’Arsenic. La qualité actuelle des ressources en eau dans le bassin de Didagou est non satisfaisante, malheureusement ces eaux sont par ignorance consommées par la population.
Impact of informal sector tax revenue on capital growth in Ebonyi State Capital, Abakaliki
Authors: Awa Felix N.
Published: June 2022

The study examined the effect of informal sector tax revenue on capital growth in Ebonyi State Capital, Abakaliki. The study adopted Ex-post facto research design in obtaining secondary data, covering 21 years (2000–2020) from the State Internal Revenue Service and the Ministry of Budget and Planning, Abakaliki. The data collected were tested using Ordinary Least Square (OLS) regression. The findings revealed that tax collected from Traders’ unions, Petty traders, and Market men and women had a significant effect on capital growth in Abakaliki, the State Capital. This is evident from the monumental capital projects being executed by the government in Abakaliki, the capital city. The study recommended that the government should not only create an enabling environment for the informal sector to thrive but should also give all necessary assistance/support for its survival because the sector has contributed to the capital development of the state capital through the tax revenue generated.

Mortality of fish seeds is recognised as one of the major factors responsible for serious economic losses in fish culture business. A preliminary investigation on the effects of aqueous extracts of dried African mahogany, Khaya ivorensis bark on the growth, survival, haematology and histology of Clarias gariepinus fingerlings was conducted. A total of 135 C. gariepinus fingerlings (1.41±0.03 g/fish) were randomly allocated into three treatments, T1 (Control), T2 and T3, and fed with three different diets (40% CP) D1, D2 and D3 containing 0g/L, 25g/L and 50g/L aqueous extracts of K. ivorensis bark respectively. The experimental fish were fed ad-libitum for a period of 28 days in rectangular plastic containers (15x25x30cm3 ) and water exchange was done daily. Experimental data were analyzed for statistical differences in the growth, survival indices, haematology and histology of experimental fishes using analysis of variance (ANOVA). There was no significant difference (p>0.05) in mean weight gain of Control (2.91±0.68g) and T2 (2.20±0.20g) but T3 (1.79±0.39g) was significantly low. There was a significant difference in the survival (S) of experimental fish with the S (%) values of 73.67±13.50, 68.67±16.50 and 57.00±10.00 for T2, T3 and control respectively, no significant different in the feed conversion ratio (p>0.05) in the experimental groups. The haematological characteristics of all experimental fish were not significantly different, though the packed cell volume, PCV (%), haemoglobin count, HB (g/dl) and red blood cell, RBC (million/mm) were in the order T2˃T3˃Control having mean values of 22.71±4.5˃21.67±5.1˃19.67±1.53 (PCV); 22.67±4.51˃2.67±6.51˃19.67±1.53 (HB) and 2.09±0.47>1.99±0.57>1.73±0.13 (RBC) for T2, T3 and control respectively. The white blood cell, (No/mm) was highest in T1 (4.03±0.25) and least in T3 (3.67±1.35). Although there was no degeneration, the histological characteristics of liver of the experimental fish ranged from moderately diffused to fewer hepatocytes when compared to the normal liver, of the control. It is therefore concluded that Khaya ivorensis bark can be included in the diet of Clarias gariepinus fingerlings at 25g/L aqueous extract for good growth and high survival rates of fish under culture

Taxonomy and biodiversity is an important aspect of fish studies as it gives fish scientists information about the types of fish present, their name and classification based on discrete sets in a given locality. This study is on the taxonomy and bio-diversity of Cichlids collected from the Eniong River and the Lower Cross River in the Niger Delta, Nigeria between January and June 2020. A total of 358 cich-lids were collected from three sampling stations (the Eniong River, the confluence and the lower Cross River). Sampling was conducted with active and passive sampling techniques with the help of local fishermen using various fishing gears including beach net (10 – 15 m length, 2 –3.5 m height, mesh size of 0.5 – 5cm), fixed gill net (40 – 60 m long, mesh size 15 – 57 mm), cast net (2 – 5 m diameter, mesh size 15 – 20 mm) and local traps (made from raffia palm). The sampling du-ration with the fishing gear and methods were approximately the same. Gill nets and traps were set between 1600 h and 1800 h and fishes caught were removed from the gear between 0600 h and 0900 h the next day. Fish were identified using morphological and meristic traits. The species found and percentage abundance were; Coptodon zilli (5.9%), Coptodon dageti (31.2 %), Coptodon guineensis (16. 4%), Hemichromis elongatus (6.4 %), Hemichromis fasciatus (2.2%), Ore-ochromis niloticus (5.3%), Oreochromis aureus (0.8%), Sarotherodon melanotheron (3.6%), Sarotherodon galileus (0.8%), Sarotherodon macrocephala (1.95%), Chromidotilapia guntheri (10.3%), Pelmatolapia mariae (12.3%), Tylochromis sudanensis (1.7%) and the unidentified species(0.8%). There was higher abundance of cichlids in Eniong River (36%) than in the confluence (34%) and lower Cross River (30%). Simpson’s diversity index was 0.97 - 0.98 in the three stations. Shannon-Wiener’s index of diversity was 2.18 in Station 1, 1.76 and 1.68 in stations 2 and 3 respectively. Margalef index of diversity was 2.05 in station 1 and 1.66 and 1.71 in stations 2 and 3 respectively. Some species ap-peared to be specific in their habitat; O.niloticus, O.aureus, S. macrocephala were found in freshwater. S. galileus in the estuarine habitat while all other spe-cies were found in all the stations. A dichotomous key which will serve as a guide for fish scientist in the field was prepared using morphomeristic characters.

Published: June 2022

This research was carried out to evaluate the effective and efficient treatment of abattoir wastewater using calcium hydroxide coagulant. Samples were collected from an abattoir unit in Ikpoba-Okha Local Government Area, Benin City, Edo State. The raw samples were characterized to determine: Dissolved oxygen (DO), chemical oxygen demand (COD), biochemical oxygen demand (BOD), temperature (T), pH, electrical conductivity (EC), turbidity, total dissolved solids (TDS), total suspended solids (TSS), total alkalinity (Alk), chloride, total Kjeldhal nitrogen (TN), hardness, potassium, phosphorous and total bacteria count (TBC). Thereafter, the samples were treated with several doses of calcium hydroxide coagulant (2g, 4g, 6g, 8g, 10g, 12g, 14g, and 16g). Results obtained were used to determine the optimum coagulant dosage in a plot of percentage COD against masses of coagulants used. From the optimum dose obtained (12g Ca(OH)2), a batch treatment was carried out. The treated wastewater was further characterized to ascertain compositional changes. Result revealed increase in oxygen and substantial reduction in chemical oxygen demand, total nitrogen, phosphorus and turbidity. Biochemical oxygen demand and total solids were also reduced. The treated effluent could be discharged into the environment without fear of pollution and may be reused for agricultural purposes.
“Shaping the new freedom”: A reflexive thematic analysis on patients’ post cure needs after years of living with hepatitis C

Published: June 2022

BACKGROUND: Direct-acting antivirals present a treatment opportunity that provides high rates of sustained viral response even for people who have lived for years with hepatitis C virus (HCV) infection. While it is known that liver-related morbidity and mortality can be decreased and many symptoms reversed, this population's need for post-treatment professional support has not been extensively assessed. Therefore, our study aimed to describe the experiences of patients cured of chronic HCV infection and explore the meaning of these experiences regarding specific follow-up care needs within the context of the Swiss health system. METHODS: For this qualitative study, we applied a reflexive thematic analysis approach with a social constructivist orientation. Twelve participants shared their experiences of being cured and their needs regarding follow-up care. Subsequently, the data were analysed in an iterative process based on Braun and Clarke's six phases of analysis. RESULTS: In the overarching theme, participants summarised their new situation with the statement, “being cured feels like being released from a cage”. They experienced striking health improvements with overwhelmingly positive influences on their everyday lives. This experience was characterised for all participants by important changes on three levels. We categorised these in three sub-themes: a) “the ball and chain have been lightened”: this sub-theme illustrates the reduction of social limitations and emotional stress; b) “the gnawing at the liver has let up”: this signifies relief from physical symptoms and strongly improved well-being. And under the third sub-theme, “shaping the new freedom”, the participants described their new situation as a sometimes-stressful challenge because they had to reorient their self-management. They shared their concerns regarding the ongoing stigma of HCV infection, feeling insecure in their own health after being cured, and learning how to use their heightened sense of confidence and openness to enact behavioural changes that would improve their health-related lifestyles. CONCLUSION: The findings of this study provide insights into treatment experiences of patients cured of chronic HCV infection and the need for follow-up care even after successful virus eradication. The results can sensitise healthcare professionals to patients’ post-cure challenges and guide their care interventions. Some of these challenges, such as dealing with stigma, can be addressed during treatment; other needs, like providing motivation to engage in healthy behaviour, may warrant targeted follow-up.

Published: June 2022

El objetivo de la investigación fue describir las experiencias educativas que evidencian la consideración de las Inteligencias múltiples en los entornos digitales de la Unidad Educativa Fiscomisional “Sathya Sai”, al observar que en los entornos digitales solo se toman en cuenta unas pocas inteligencias como son las inteligencias visual-espacial, la lingüístico-verbal, y la lógico-matemática; quedando en segundo plano el resto de las inteligencias múltiples que pudieran emplearse para ampliar los procesos educativos. La misma se desarrolla en el marco de una metodología positivista con enfoque cuantitativo, no experimental de carácter descriptivo. La fuente de información la conformaron 30 estudiantes, a estos se les aplicó una encuesta estructurada cuyo instrumento fue un cuestionario con 10 preguntas cerradas.  El análisis de la información se realizó con el apoyo de la estadística descriptiva. De la representación porcentual surgida en los resultados, se evidencia la persistencia en el alto índice de incidencia en la utilización de ciertas inteligencias sobre otras. La conclusión del estudio se enmarca en torno a la necesidad de extender el uso de todas las inteligencias para profundizar en el aprendizaje y complementar los conocimientos mientras el estudiante se desarrolla cognitivamente.

Toprak gibi, çok kıymetli ve miktarı artırılamayan, yanlış uygulamalarla üst verimli kısmı azalan milli servetimizi korumak için, öncelikle onu iyi tanımak, özelliklerini ve verimlilik durumunu bilmek toprak bilimciler için bir ödevdir. Bu ödevin en son yerine getirilmiş, görsel hali toprak haritalarıdır. Bir ülke veya bölge topraklarında meydana değişikliklerin izlenmesi ve gerekli önlemlerin alınması için toprak haritalarının belirli süreler içerisinde yenilenmesi, ilk haritaların oluşturulmasından daha önemlidir. Türkiye toprak haritalamasındaki gelişmelerin kronolojik olarak verildiği bu çalışmada, 1958-2021 tarihleri arasında hazırlanan toprak haritaları sunulmuştur. Çalışma alanımız olan Iğdır ili örneklendirmeleri, toprak haritaları üzerindeki okumalarla yapılmıştır. Köy Hizmetleri Genel Müdürlüğü (KHGM), Kars ili arazi varlığı paftalarındaki Iğdır ili sınırları sayısallaştırılarak, Coğrafi Bilgi Sistemleri (CBS) ortamında tüm karakteristikler öz nitelik tablosu halinde veri tabanına dönüştürülmüş ve Toprak Reformu Genel Müdürlüğü 1/25.000 ölçekli sayısal toprak verileri ile birlikte kullanılarak; büyük toprak grupları, arazi kullanım kabiliyet sınıfları ve problemli arazileri kapsayan çok amaçlı bir Iğdır ili haritası hazırlanmıştır. 1958 yılında, Iğdır ili için 1 büyük toprak grubu ortaya konmuş iken; 1998 yılından bugüne kadar 7 büyük toprak grubu belirlenmiştir.

Diabetes mellitus sebagai salah satu penyakit kronik dengan solusi pengobatan yang panjang menggunakan obat kimia dan memiliki tingkat kejenuhan pengobatan yang tinggi sehingga banyak orang beralih kepada pengobatan alternatif. Salah satunya adalah dengan menggunakan obat tradisional, namun pemahamannya masih bersifat reduksionis atau mengganti obat kimia menjadi obat yang berasal dari bahan alam. Penelitian ini bertujuan untuk mengetahui manfaat dan pengaruh jus buah pare yang dibuat secara tradisional terhadap glukosa darah dan kualitas hidup pasien diabetes mellitus yang menjalani perawatan dengan skema pengobatan holistik. Penelitian dilakukan pada pasien diabetes mellitus tipe 2 pada tahap awal yakni pasien yang baru terkena diabetes mellitus tanpa komplikasi penyakit lain. Kadar glukosa darah dicek sejak pasien mulai perawatan sampai pasien pulang, begitu juga pemantauan kualitas hidup menggunakan kuesioner instrumen SF-36. Hasil penelitian menunjukkan bahwa jus buah pare yang diolah secara tradisional memberikan pengaruh yang signifikan terhadap kondisi klinis pasien dengan skema pengobatan holistik yang diukur pada kadar glukosa darah sewaktu sebesar 51,5% dengan signifikansi 0,001. Pada kualitas hidup pasien memberi pengaruh sebesar 61,3% dengan signifikansi 0,000 yang berarti ada perbedaan yang berbeda bermakna pada kadar gula darah sewaktu dan kualitas hidup pasien sebelum dan setelah diberika jus buah pare.

Statins are widely used in patients with cardiovascular disorders. However, the issue of the feasibility of prescribing the high-dose and medium-dose statins to elderly patients remains a matter of discussion. That is due to higher prevalence of the statin therapy side effects in this age group. The paper reports a clinical case of statin-induced myopathy, associated with the prolonged use of atorvastatin, in the elderly patient.

Osteoarthritis associated with metabolic syndrome (MetOA) is a clinical phenotype defined by the role of obesity and metabolic syndrome as risk factors, as well as mild chronic inflammation. Obesity is an established risk factor for developing osteoarthritis (OA) not only in the knee but also in the hands. Metabolic syndrome is also a risk factor for the development of OA, and the cumulative effect of the various components of the syndrome is combined with the independent action of each individual component (diabetes mellitus, dyslipidemia and/or arterial hypertension). The higher incidence of OA in obese patients is associated with several factors. One of them is a large fat mass, which increases the stress on the joints. Another is the production of pro-inflammatory mediators by adipose tissue, which negatively affect the tissues of the joints. Finally, patients with OA, with or without metabolic syndrome, are at increased risk of cardiovascular mortality, not only due to a sedentary lifestyle, but also due to common risk factors. Among them is the mild inflammation seen in patients with metabolic disorders. Thus, primary prevention and appropriate treatment of obesity and metabolic syndrome can delay the development and slow the progression of OA.
