The Use of Social Networking among Senior Secondary School Students in Abuja Municipal Area of Federal Capital Territory, Nigeria

The present study examined the use of social networking among senior secondary school students in Abuja Municipal Area Council of FCT. The study employed quantitative method for data collection involving questionnaire administration. Fifteen questions with Likert model and ten yes/no responses in a questionnaire were personally administered to 400 randomly selected students. The obtained data were analyzed using statistical package for social sciences (SPSS). The results revealed that many students used social networking in high magnitude especially Facebook and that they spend increasing amount of quality time on these networks. This study will be of immense benefit to the Federal Capital Territory Administration as it has shown the potent dangers of uncontrolled use of these social networking by students and therefore the need to put in place measures to forestall its alluded negative effects becomes imperative.

E-teaching of Arabic to non-native speakers in pandemic

The article discusses modern media used during teaching Arabic to non-native speakers, especially e-learning which has become required in the new world, especially in the spread of infectious diseases. This situation urges the teaching system to switch to E-learning, which helps in studies, particularly during the lockdown period in the pandemic. It benefits the teaching by modern technologies and media in transmitting the language to learners. Learning Arabic has increased in recent times, and learners as a modern generation are using modern technologies to learn. This research on E-teaching of Arabic to non-native speakers in a pandemic is urgent, especially in the pandemic era. It must use media in teaching, especially in teaching Arabic. With the emergence of the Corona pandemic that has spread throughout the world, the demand raises high. The results were as following: use of media in education makes teaching more effective and integrated, give effective results, raises the competence of the teacher and the recipient of the language, increases attention and excitement among students, and develops the ability to teach with communication, and the media facilitate the education process even in the spread of diseases and does not interrupt the chain of education between the learner and the teacher. We arrived with results that the necessity of acquaintance with modern methods and technical means and using them will give fruitful results

Phosphorus Fertilizer Response to Onion (Allium cepa L.) Yield in Punjab, Pakistan

Background: Onion (Allium cepa L.) is one of the most essential plants in food with high nutritional value. However, application of right dose of phosphorous (P) is one of the constraints to the profitable onion yields in soils deficient in P.Methods: A systematic study to confirm the best dose of P was conducted for six years in the P deficient soil in farmers’ fields. Based on the findings obtained from 2008-09 to 2010-11, the research was undertaken to determine the effect of different phosphorus levels on the yield of onion in the Randomized Complete Block Design (RCBD) with a total of 114 replicates  in 2011-12 to 2012-13. Four treatments (160, 210, 260 and 310 kg P2O5 ha-1) were tested with N and K at 100 kg ha-1.Results: From the results of this investigation, the variance analysis showed the substantial P impact. The maximum marketable bulb yield (19.03 t ha-1) was obtained from the fertilizer combination NPK @ 100-310-100 kg ha-1 and was shown to be statistically higher than all other treatments.Conclusion: Nonetheless, the nutshell of the overall economic study is that poor farmers (Land holders >12 acres) may have options to select the NPK fertilizer combination @ 100:210:100 kg ha-1 and the average farmer may have options to select the NPK fertilizer combination @ 100:260:100 kg ha-1. But rich farmers (Land holders >25 acres) who can spend more money on fertilizers and are interested in the higher gross margin should follow the combination of NPK fertilizers @ 100:310:100 kg ha-1 to profitably increase their gross margin and maintain soil fertility for onion cultivation in Punjab, Pakistan.   Keywords: Onion; NPK; Plant nutrition; Phosphorus; Pungency

DNA methylation of human choline kinase alpha gene

Increased level of choline kinase (CK) is a common feature in cancers and inhibition of this enzyme has been applied as anticancer strategy. DNA methylation of gene promoter especially at CpG island is associated with suppression of gene expression. Despite the importance of CK especially the alpha isoform in cancer pathogenesis, epigenetic regulation of ckα expression has not been investigated. Hence, this study aimed to determine the effect of DNA methylation on ckα promoter activity and gene expression by using hypomethylating (5-aza) and methylating (budesonide) agents. The level of DNA methylation in the second CpG island of ckα promoter was determined by PCR-based method. 5-aza and budesonide increased the methylation of the selected CpG island compared to untreated control. Treatment with the drugs produced opposite effect, with 5-aza induced ckα promoter activity and gene expression while budesonide suppressed the promoter activity and mRNA level of this gene. Deletion of a region containing the second CpG island on ckα promoter resulted in significantly lower promoter activity. In conclusion, this study showed that DNA methylation could be one of the mechanisms that regulate the expression of ckα gene

Causal Link between Financial Globalisation Uncertainty, Economic Growth, Environmental Degradation and Energy Consumption in ASEAN+3 Countries

This paper aims to examine the causal linkage of financial globalisation uncertainty, Environmental Degradation, economic growth and energy consumption for ASEAN+3 countries using second-generation approach for the period between 1970–2019. The results of second-generation unit root test revealed that economic growth and financial globalisation uncertainty were stationary at level, while energy consumption and environmental degradation were stationary at first difference. In addition, the Larson cointegration test showed that long-run cointegration exists between the variables. Similarly, we found that economic growth and environmental degradation have significant positive influence on energy consumption. However, financial globalisation uncertainty has insignificant influence on energy consumption. The results of causal relationship indicated a bidirectional causal relationship between financial globalisation uncertainty and energy consumption; environmental degradation and energy consumption; and economic growth and energy consumption

The Muslim headscarf and face perception: "they all look the same, don't they?"

YesThe headscarf conceals hair and other external features of a head (such as the ears). It therefore may have implications for the way in which such faces are perceived. Images of faces with hair (H) or alternatively, covered by a headscarf (HS) were used in three experiments. In Experiment 1 participants saw both H and HS faces in a yes/no recognition task in which the external features either remained the same between learning and test (Same) or switched (Switch). Performance was similar for H and HS faces in both the Same and Switch condition, but in the Switch condition it dropped substantially compared to the Same condition. This implies that the mere presence of the headscarf does not reduce performance, rather, the change between the type of external feature (hair or headscarf) causes the drop in performance. In Experiment 2, which used eye-tracking methodology, it was found that almost all fixations were to internal regions, and that there was no difference in the proportion of fixations to external features between the Same and Switch conditions, implying that the headscarf influenced processing by virtue of extrafoveal viewing. In Experiment 3, similarity ratings of the internal features of pairs of HS faces were higher than pairs of H faces, confirming that the internal and external features of a face are perceived as a whole rather than as separate components.The Educational Charity of the Federation of Ophthalmic and Dispensing Opticians
