“Hac ibadetindeki bazı uygulamaların vadî hükümlerden “sebeple” olan ilişkisi konulu makalemizin gayesi; konu hakkında sebep-hüküm arasındaki bağlantıyı, bu ibadetin son bulduğu vakti, mezheplere göre değerlendirip fıkıh usulündeki
gerekçeleriyle birlikte temellendirerek ifade etmektir. Bu konu hakkında gerek klasik kaynaklarda ve gerekse günümüz kaynaklarında birçok çalışma bulmamız mümkündür. Fakat konunun zamanla ilişkili olan tarafının müstakil bir başlık
altında değerlendirmeye tabi tutulmasına rastlanmamıştır. Araştırmamızda mümkün olduğunca fıkhî mezheplerin görüşleri mukayeseli olarak ortaya konulmaya gayret edilmiştir. Aslı itibariyle teklifi gerektiren bütün hükümler; ayın,
dünyanın ve özellikle de güneşin hareketlerine göre hayat bulmakta ve önem kazanmaktadır. Bu durum da zaman kavramının ibadetler için vazgeçilmez olduğunun önemli bir göstergesidir. Fıkıh usulünde zaman sadece namaz, oruç ve hac
ibadetleri için “sebep” olarak kalmamakta, bu ibadetlerin dışındaki diğer ibadetler için de önem ifade etmektedir. Meshin geçerliliğinde, kurban kesmede, zekât vermede ve diğer ibadetlerde başlangıç ve bitiş vakitleri Müslümanların
yükümlülüklerini ifa etmede vaktin çok önemli bir disiplin olduğunu somutlaştırmaktadır. İbadetlerin gerçekleşmesinde; sebep, şart, mâni gibi vadî hükümler mükellefler açısından zihinlerde birtakım sorular meydana getirmektedir.
Konunun önemi sebebiyle Şâri’in güneşin batışına bağladığı hac ibadetiyle ilgili olarak güneşin hareketleri ve bu hareketin uygulamaya olan etkileri ve sınırları araştırılmıştır. Hac ibadetinde uygulanan birtakım menâsik hakkında
fakihlerin ihtilafı, bu ihtilaflardaki râcih görüşler ve bu görüşlerin delilleri birlikte zikredilerek fıkıh usulündeki vadî hükümlerle ilişkilendirilmiştir. Araştırmamızda ilk olarak fıkıh usulündeki vadî hükümlerden; rükün, şart,
sebep, illet ve mâni hakkında kısaca bilgi verilecektir. Daha sonra güneşin batmasının hac menâsikini gerçekleştirmedeki yeri değerlendirilecektir. Buna bağlı olarak sırasıyla: Gün batımından önce Arafat’tan Müzdelife’ye inmek,
gün batımına kadar Arafat’ta vakfe yapmak, Cemretü’l-Akabe’nin vakti, teşrik günlerinde geceleyin taş atma, Mina’dan erken dönmek isteyen kimsenin durumu ve son olarak da Mina’dan ayrılmaya niyetlenip hazırlanan kimsenin Mina’da
gecelemesi konuları değerlendirmeye tabi tutulacaktır.

Dinin temel kaynağı olan Kurʾân’da üzerinde durulan konulardan biri, anne ve babaya karşı sergilenmesi gereken tavırlardır. Bu çerçevede insana, anne ve babasına iyi davranması, tatlı ve güzel söz söylemesi ve yaşlandıklarında azarlamadan
onlarla ilgilenmesi emredilmektedir. Konunun önemine binaen bu emirler, bazen Allah’a şirk koşmamak gerektiği hususunun ardından, bazen de “emrettik, vasiyet ettik” gibi vücûb ifade eden lafızlarla zikredilmektedir. Hadis kaynaklarındaki
çok sayıda rivayette bu hususların, Kurʾân’ı teyit edici ve açıklayıcı şekilde mevzubahis edildiği anlaşılmaktadır. Bu çalışma, bu rivayetlerden Abdullâh b. Abbâs, Enes b. Mâlik ve Câhime b. el-Abbâs’tan nakledilmiş üç rivayeti
sened ve metin açısından ele almayı amaçlamaktadır. Üç rivayetin ortak noktası, zahiri itibariyle “cennetin annelerin ayakları altında” olduğunu haber vermiş olmalarıdır. Öncelikle tespit edilen bu rivayetler, sened tahliline tabi
tutulmaktadır. Böylece onların Rasûlullah'a (s.a.v.) aidiyetleri ve sıhhat durumları ortaya konulmaktadır. Ardından ilgili ayet ve rivayetler ışığında rivayetlerin metin tahlili yapılmaktadır. Böylelikle bu rivayetlerin hangi bağlamda
söylendiği, “cennetin annelerin ayakları altında” olmasının ne anlama geldiği ve cennetin neden yalnızca annelerle ilişkilendirildiği gibi hususlara cevap aranmaktadır.

Optimized model for rapid battery charging using constant current constant voltage protocol
Authors: Emeruwa, C  , Edem, M. E.
Published: February 2022

This research, which aims to find the best constant current, constant voltage parameters for charging a battery in the quickest time possible, subjects battery cells to varied charging and discharge rates in order to determine their rate capabilities. Cycling the cells using constant current, constant voltage charge in 60 minutes and 90 minutes discharge for 400 cycles examines the effects of the charging current Charge Rate and the voltage limit for the constant voltage on the battery's discharge capacity. The results obtained showed that 1.3C-rate and 4.3V voltage limit produced the utmost discharge capacity and cycle life. During the cycling period, the cell temperature was under 39°C with a capacity loss after 400 cycles of 8%. A 3 percent capacity gain was seen after charging the batteries using the cccv methodology for 180 minutes and then discharging them for 120 minutes. This low capacity loss after 400 cycles suggests that an optimal charging model employing the cccv protocol is possible.
Effect of vulcanizer solution on the blood lipid profile of Wister albino rats
Authors: Otitoju Olawale  , Moses A. Abah
Published: February 2022

Inhalant abuse is a worldwide problem that is common especially in individuals from minority and marginalized populations, and is strongly correlated with the social determinants of health. The abuse of inhalants such as vulcanizer solutions among Nigerian youths, for the purpose of mind-alteration or getting high is on the increase at an alarming rate. These inhalants are pharmacologically diverse products that are selected for their low price, legal and widespread availability, and ability to rapidly induce euphoria. The aim of this research was to subject wistar albino rats to different vulcanizer solutions and investigate the possible effects of these solutions on the social behavior as well as significant changes in the concentrations of blood lipid profile parameters (TChol, TAG, HDL, and LDL). A commercial assay kit from Randox laboratories Ltd was used for the determination of the parameters. The acute effects of administration of the vulcanizer solution through inhalation on the High density lipoprotein level of albino rats showed that rats administered with Miliki diamond solution (group A) (1.1±0.04a) and OSHN diamond solution (group D) (1.0 ±0.03a) is statistically significant (p<0.05) having lower High density lipoprotein compared to the control group (E) (1.4±0.85b). There was an increase in the level of total cholesterol in group D (OSHN diamond) (5.2±0.35a) which is not statistically significant (P<0.05) compared to the control groups (E) (4.8±0.10a). The results also showed a decrease in the level of low density lipoprotein in all test groups compared to the control group which is not statistically significant (P<0.05). On the chronic inhalation, there were significant increase (p<0.05) in the total Cholesterol level of group D animals (4.5±0.08c) compared to the control group (4.3±0.29b). There was neither an increase nor a decrease in the level of total cholesterol of the remaining groups which are not statistically significant (P<0.05) when compared to the control group. On HDL level, only OSHN diamond solution decreased the serum. Despite the increasing and decreasing effects of these solutions, they have been shown to be statistically not significant (p<0.05) when compared with those of the control. The changes seen in the behavior as well as blood lipid profile of the wistar albino rats could be attributed to the effects caused by the various chemical constituents (such as toluene, benzene, ethyl, etc) of vulcanizer solutions. Therefore, abusers of vulcanizer solutions may be susceptible to various cardiovascular diseases as well as diseases of the liver and other organs, thus adding to the number of people with the aforementioned diseases in this generation.

Émancipation identitaire : une analyse de La discrétion de Faïza Guène
Authors: Ardenghi Fulvia
Published: February 2022

Faïza Guène’s sixth novel La discrétion focuses on a Maghreb Muslim woman who, having migrated to France, is trying to reconstruct her personal and family history. It is a memoir whose aim is to make the experiences of first-generation migrants an integral part of cultural memory. This search for identity concerns the children of those migrants who try to relate to a fragmented, often suppressed family history they did not experience themselves, but whose burden they nonetheless inherited. The aim of this article will be to prove that what allows both the protagonist of the story and who tells it to free themselves from this overwhelming past is in fact the narrative itself, a process of identity construction with which each author is confronted.

Радиационные горелки цилиндрической формы, у которых длина газопроницаемого излучателя превышает диаметр, перспективны к применению в современных водогрейных и паровых котлах. Важным компонентом горелки является система подачи предварительно перемешанной газовоздушной смеси в объем излучателя. Рассмотрены две стратегии ввода топливно-воздушной смеси через торец цилиндрической радиационной горелки с тонкослойным пористым излучателем из Ni-Al-Cr сплава:(1) струйный ввод смеси из газоподающего канала с заданным профилем и (2) распределенный ввод смеси посредством тонкослойной мелкопористой вставки, соосно размещенной в объеме полости излучателя. В диапазоне мощностей 4,0-9,1 кВт и коэффициентов избытка воздуха 1,0-1,7 изучены температурные характеристики горелки, эмиссия оксидов азота и шума. Установлено, что вторая стратегия ввода топливной смеси позволяет обеспечить более равномерный нагрев излучателя, значительно снизить шум и эмиссию оксидов азота горелки.

This chapter presents a Land Use Cover Change (LUCC) model application developed for Greater Sydney. It aims to help decision making in the context of the strategic and spatial planning of Greater Sydney. To this end, the model simulates the dynamics of industrial, low density residential and medium-high density residential areas at spatial resolution of 100x100 m.A series of three Land Use Maps at 30m were specifically developed for the modelling exercise. They determine part of the exercise´s limitations, such as the model simplicity and the short timeframe of the simulation (2006-2011-2016). Future efforts should focus on the simulation of population and job growth, exchanges between regions and the application of the model for scenario analysis and impact assessment.All data of the modelling exercise are openly available at the CityData portal of the City Futures Research Centre.

The study investigated farmers’ adoption of yam minisett technology in Agricultural Zone 3, Rivers State, Nigeria. The objectives of the study were to examine farmers’ level of awareness of yam minisett technology in the study area, to access the extent of adoption of yam minisett production technique in the study area, examine the constraints to adoption of yam minisett technology in the study area and to determine the influence of yam minisett utilization on the yield of yam in the study area. The study adopted a survey research design. A sample of 360 farmers was selected using random sampling technique. Structured questionnaire was used for data collection. Frequency, percentages, mean and standard deviation were used to analyze and realize the objectives of the study. The findings of the study reveal that farmers in the study area had low awareness level about the yam minisett technology and adoption of the yam minisett technology. Cost of innovations, lack of technical efficiency and low sprouting rate of minisetts, poor extension delivery service and the top-down extension approach which does not take cognizance of farmers-identified production problems, lack of youth participation and involvement in farming (yam production) as a result of search for white-collar jobs, socio-economic characteristics such as educational level or background, and lack of land to commercially produce in quantity, among others are constraints to the adoption of yam minisett technology in the study area. It was recommended that the farmers should be encouraged to engage in training and to seek financial assistance in order to overcome the problem of scarcity and high cost of inputs.

The experiment was conducted at the Federal College of Forestry Demonstration Farm in Jos, Plateau State, Nigeria during the 2018 and 2019 growing seasons to determine the efficacy of intra-row spacing on the growth and yield of groundnut cultivars on the Jos, Plateau, Nigeria. A Randomized Complete Block Design (RCBD) was used involving four row spacings (15, 25, 35 and 45 cm) and three groundnut cultivars (SAMNUT 22, SAMNUT 23, and SAMNUT 24) arranged in 12 treatment combinations and replicated three (3) times on a 3 m x 3 m plot size with an alley of 0.5 m. Data were collected on plant height (cm), numbers of leaves, branches and pods plant-1, canopy width (cm), 100 seeds weight (g), plant biomass (kg ha-1) and yield (kg ha-1). The data collected was subjected to analysis of variance (ANOVA) to test the significance between the treatment effects using F-test in XLSTAT 18 statistical package and where significance was observed, means were separated using Duncan’s Multiple Range Test. The experiment showed that intra row spacing and cultivar significantly (p≤0.001) affected the growth and yield characters of the groundnuts. An intra-row spacing of 45 cm produced the highest growth characters of groundnut and 25 cm row spacing produced the highest yield characters while SAMNUT 24 out yielded the other cultivars producing the highest growth and yield. Based on the afore mentioned, it can be concluded and recommended that SAMNUT 24 is the most suitable cultivar and 25 cm intra row spacing is the optimal spacing for groundnut production in the study area.

In ethno-medicinal practice in the South-western part of Nigeria, the rhizome of Anchomanes difformis is claimed to be effective in the management of mental illness. This study determined the antidepressant effects of hydro-alcoholic extract and fractions of Anchomanes difformis rhizome and the likely mechanisms of action of the extract and the most active fraction in mice. The extract was partitioned into n-hexane, ethylacetate, butanol and distilled water to obtain n-hexane, ethylacetate, butanol and residual aqueous fractions, respectively. The extract and fractions were administered to mice of both sexes (18 to 25 g) at 60, 125, 250, 500, and 1000 mg/kg, orally. Tail suspension and forced swimming anti-depressant animal models were used. The likely mechanism of anti-depressant action was assessed using yohimbine and cyproheptadine. The data were analyzed using one-way ANOVA followed by Student-Newman-Keul’s post hoc test with the level of significance taken as p<0.05. The extract and ethylacetate fraction at 60 to 250 mg/kg significantly (p<0.05) reduced the period of immobility in both the tail suspension and forced swimming tests without significantly impairing the locomotor activity, suggesting an anti-depressant effect. This effect was reversed by yohimbine (1 mg/kg, i.p.), an α2-adrenergic receptor antagonist, yohimbine and also by cyproheptadine (0.5 mg/kg, i.p.), a serotonergic receptor antagonist. The study concluded that the extract and ethylacetate fraction of A. difformis rhizome possessed an anti-depressant effect in mice which was probably mediated through α2-adrenergic and serotonergic pathways.

QSAR models of 25 iminoguanidine derivatives with inhibitory HemO were developed. The QSAR model was built by using DFT-MLR and the best QSAR model has R2, Q2 values of 0.6569 and 0.5493 for cross-validated and non-cross-validated. The predictive ability of QSAR model was further validated by a test set of 7 compounds, giving R2pred value of 0.7123. 3D-QSAR and docking studies were used to find the actual conformations of chemicals in active site of HemO, as well as the binding mode pattern to the binding site in HemO enzyme. Molecular dynamics and simulations study revealed that A-chain of HemO protein was stable at and above 100ps with respect to temperature (at and above 298 K), electrostatic (at and above 57500 kJ/mol), kinetic energy (at and above 12200 kJ/mol) and total energy (at and above 30500 kJ/mol). The information provided by QSAR, 3D-QSAR and molecular docking may provide a better understanding of the structural requirements of iminoguanidine-based inhibitors of HemO and help to design potential antibacterial molecules. Four (4) new compounds (4A, 5A, 6A, and 7A) with high predicted antibacterial activities have been theoretically designed and they are expected to be confirmed experimentally.

INTRODUCTION: Utilization of digital devices create some problems for users, such as, mental disorder, visual problems, headache, weight gain and unnecessary time consumption. Therefore, this study aims to identify the information about the practices on the use of digital devices, its impact on physical health and pattern of self-care among the university students involved in different professions.

MATERIALS AND METHODS: MPhil scholars involved in different professions (n= 315) of Nepal Open University (NOU) had participated in this cross-sectional online survey during January 2019 to August 2019. Multivariable analysis was employed to obtain rate ratios and chi-square test was used for the association of the use of digital devices with physical health problems.

RESULTS: Socio-demographic factors like age was significantly associated with neck pain (p=0.02) and stiffness in hands/arms (p=0.04), while profession was associated with weight gain and difficulty in sleep (p=0.04). Moreover, the use of tablets or taking tea or coffee during the use of digital devices was associated with headache among university students (p=0.05) with small effect sizes. Additionally, we found that headache (p< 0.001), and weight gain (p= 0.01) were significantly associated with the daily use of computer and TV respectively.

CONCLUSIONS: Physical health problems among the subjects who used computers and TV were relatively high as compared to the subjects who used laptops. Self-care measures taken by participants for physical health problems involved the use of medicine and meditation.

INTRODUCTION: Organophosphorus is one of the most common causes of poisoning worldwide. Organophosphorus (OP) poisoning is a major public health problem in Nepal. This study was conducted to observe the epidemiological pattern and mortality in patients with OP poisoning admitted to provincial hospital Janakpurdham, Nepal.

MATERIALS AND METHODS: It was a retrospective study. All the consecutive poisoning cases due to op compound admitted through emergency either in the ward or ICU of the provincial hospital from 15 May 2020 to 15 November 2020 included in the study.

RESULTS: A total of 160 cases of poisoning were admitted through emergency either in the medical ward or ICU of the provincial hospital. Out Of these 81 (51.63 %) was OP poisoning. Among 81 cases 51.85 % were male.70.37 % of cases were from the young adult group i.e., 15 to 30 years. 38.37 % were housewives. Among all included cases 43.20 % had consumed Methyl parathion (Metacid) followed by Phorate 24.69 %. 55 % of total cases were from Dhanusha district followed by Mahottari and Sarlahi. The mortality rate was 14.81 % of total admitted cases, with an average of 5.7 days of hospital stay in the recovered case.

CONCLUSIONS: OP poisoning is a major public health problem in province 2. It affects mostly the young age population. Housewives are at more risk of poisoning. The mortality in patients with OP poisoning is high even if antidotes are available. Considering the common occurrence and full curability of the condition early arrival to the hospital, timely monitoring, and prompt management may help to reduce mortality. With strict laws on the provision of pesticide availability, the poisoning incidence can be decreased and by proper development of infrastructure and ICU facility mortality can be decreased.
