An experiment was carried out at the Agronomy Research field of Sher-e-Bangla Agricultural University, Dhaka, Bangladesh during the period from November, 2013 to April, 2014 with a view to observe the effect of micronutrients (Zn, B and Mn) with different levels of macronutrients (NPKS fertilizers) on onion (Allium cepa L.) seed yield. The experiment was conducted with four levels of micronutrients viz. M1= Zn0B0Mn0 kg/ha, M2= Zn4B1Mn2 kg/ha, M3= Zn6B2Mn3 kg/ha and M4= Zn8B3Mn4 kg/ha and three doses of macronutrients viz. F1= N57P21K39S9 kg/ha, F2= N114P42K78S18 kg/ha and F3 =N171P63K117S27 kg/ha. All doses of micro and macronutrients are applied to the soil. Application of micronutrients and different doses of macronutrients increased number of umbels/plot, number of seeds per umbel, weight of seeds per umbel, seed yield per plant. The highest seed yield (879.9 kg/ha) were recorded from M3 treatment and the lowest seed yield (787.4 kg/ha). The positive effects of micronutrients were found in order of M3> M4> M2> M1. The F2 treatment produced the highest seed yield (957.6 kg/ha) and F1 treatment produced lowest (776.6 kg/ha). The positive effects were found in order of F2> F3> F1. Amongst the treatment combinations, M3F2 produced the highest seed yield (1027.0 kg/ha) and M1F1 produced the lowest yield (734.4 kg/ha).

The present study was conducted in district Shopian of Jammu and Kashmir in 2014 with sample size of 180 respondents. The district Shopian was purposively selected, because of the potential for the development of horticulture, mainly because 90% of the district was under apple cultivation. The data were collected from three different altitudes viz- low, medium and high altitudes. Different socio-personal characteristics viz- age, experience, education, family education, family type, family size, innovative proneness were studied from different altitudes. Attitude of the apple growers was also studied and it has been revealed that most of the apple growers from all three altitudes were having neutral attitude towards apple cultivation.

Introduction: Despite the benefits of breastfeeding, neither its duration, nor its exclusivity are respected by the majority of mothers. Among the modifiable factors and sensitive to the interventions of health professionals, the self-efficacy has been recognized as the most influential to improve the duration and exclusivity of breastfeeding.

Aim: We conducted this work to assess the factors associated with exclusive breastfeeding to 8 weeks and breastfeeding self-efficacy among mothers delivering in a Tunisian University Hospital.

Place and Duration of the Study: The maternity unit of the University hospital of Farhat Hached of Sousse in Tunisia during the period from 15th May to 15th June 2014 from birth to the eight postnatal weeks conducted among the mothers delivering in a Tunisian University Hospital.

Type of the Study: This is a descriptive study with longitudinal follow-up.

Methodology: Data collection has been carried out by a questionnaire including the French version of the Breastfeeding self-efficacy scale-Short Form.

Results: The mean of the breastfeeding self-efficacy score was 44.88 ± 11.74, 95% CI [46.99-50.78]. The score of breastfeeding self-efficacy was significantly associated to age (p = .003), to maternal education (p = .02), to the intention to breastfeed (p <10-3), to a previous positive experience of breastfeeding (p <10-3), to the vaginal delivery (p <10-3) and the exclusive breastfeeding at 8 weeks (p <10-3).

Conclusion: A new perspective for breastfeeding promotion focusing on major modifiable factors, mainly breastfeeding self-efficacy, is advocated to enhance breastfeeding duration and exclusivity rates in Tunisia.

DOI: 10.9734/AIR/2017/36610

Aims: This study was conducted to investigate the antioxidant potential, antimicrobial activity and wound healing activity of ethyl acetate, butanol, and aqueous fractions of methanolic extract of leaves of Adina cordifolia (Roxb.) a locally used leave in Jharkhand, India.

Place and Duration of Study: Department of Pharmaceutical Sciences, Birla Institute of Technology, Mesra, Ranchi between June 2014 to April 2015.

Methods: Dried powder of the Adina cordifolia leaves was extracted with methanol. The methanolic extract was then fractionated with solvents of increasing polarity; ethyl acetate, n-butanol and the residual soluble aqueous fraction. Estimation of total phenolic and total flavonoid contents for the methanol extract and all fractions was done. The free radical scavenging activity was studied in-vitro by measuring 2,2-diphenyl-1- picrylhydrazyl (DPPH) and hydrogen peroxide scavenging of methanolic extract and all the three fractions. Antibacterial activities were evaluated against four micro-organisms viz; Pseudomonas aeruginosa, Escherichia coli, Bacillus subtilis, Staphylococcus aureus using agar well diffusion method. The wound healing activity was evaluated by excision and incision wound models.

Results: Among all the three fractions, n-butanol fraction and aqueous fraction possessed high amount of phenolic and flavonoid contents as compared to the ethyl acetate fraction. Subsequently the n-butanol fraction and aqueous fraction also showed better free radical scavenging activity on DPPH and hydrogen peroxide radical than ethyl acetate fraction. Antibacterial activities were evaluated against four micro-organisms in which only the n-butanol fraction and Ethyl acetate fraction had showed effective antimicrobial activity against Staphylococcus aureus and n-butanol fraction showed better antimicrobial activity at different concentrations than Ethyl acetate fraction. Excision wound model showed highly significant effect of drugs on percent wound contraction at all the periods under study and at day 12, percent wound contraction was 96.03 ± 0.78 in test drug and 66.16 ± 1.56 in control. In incision wound model, significantly higher tensile strength was observed in standard (5.022 ± 0.052 g/mm2) and test drug (4.858 ± 0.073 g/mm2) as compared to control (2.960 ± 0.031 g/mm2). 

Conclusion: This results shows that the n-butanol fraction possess effective wound healing properties due to their antimicrobial and antioxidant activities by possessing the active compounds such as flavonoids (polyphenols), terpenes, alkaloids, saponins.

This paper presents a survey of publications on Optimal Power Flow (OPF) analysis of longitudinal power system with emphasis on the Nigerian power grid. It explained the nitty-gritty of OPF analysis. The study revealed that application of heuristic optimization techniques to OPF analysis have obviated the drawbacks of the previously used traditional optimization techniques with better solution quality, convergence time and flexibility. Although, the heuristics techniques were not flawless but well off to that of traditional techniques, a careful hybridization of both techniques seemed best off. This publication will be found handy for power system operators as well as researchers in an attempt to enhance the operations of the electrical power system.
