The effect of fish-oil supplementation on antenatal and postpartum depression: a randomized controlled trial

This was a randomized, double-blind, placebo-controlled, multi-centre trial. 051 eligible pregnant women aged 01-55 recruited from Feburary 4102 to April 4105 in Tabriz, Iran. Participants randomly assigned to receive either 0111 mg fish oil supplements from 01-41 weeks of gestation to 0month after giving birth or placebo. Subjects completed the Edinburgh Postnatal Depression Scale at enrollment, 41 ndash;51 weeks, 55 ndash;57 weeks, and at 51-25 days after birth. Primary outcomes were mean ...

Effect of vermicompost on yield and seed mucilage content of Plantago psyllium

Effect of vermicompost on yield and seed mucilage content of Plantago psyllium

This research was conducted to investigating of effect of different vermicompost substitutions (0, 25, 50, 75%) on yield and seed mucilage content of Plantago psyllium in a greenhouse experiments. In reproductive phase, spike number per plant, seeds number per spike, thousand seed weight, seed yield and seed mucilage properties were recorded. Results showed that 25% vermicompost substitution promoted the highest seed number per spike and thousand seed weight but the highest number of spikes per ...

Effect of various potassium nitrate levels on germination and morphological characteristics of Mentha longifolia

Effect of various potassium nitrate levels on germination and morphological characteristics of Mentha longifolia

Nitrogen is one of the most important plant macronutrients. Nitrate accumulation in the plants via excessive use of nitrate fertilizers, sewage wastewater and etc., can affect plant growth and development and so could be a threat for human health, animals and the ecosystem. Since the Mentha longifolia is naturally growing in the margin of contaminated water, could be a candidate for nitrate phytoremediation. As the first step to evaluate phytoremediation potential of this species, effect of ...

Investigating the Effect of Applying Polypropylene Fiber on Compressive Strength of Self-consolidating Concrete

Investigating the Effect of Applying Polypropylene Fiber on Compressive Strength of Self-consolidating Concrete

Mechanical characteristics of fiber concrete is affected by type, percentage, length to diameter ration, context resistance, size and shape of fiber, sample preparing method and size and shape of sand material. Therefore, in order to use in each case, mix design should be prepared and it must be tested. The current research have been designed and conducted in order to examine the effect of applying propylene fiber on pressure behavior of Self- consolidating concrete. Washed sand with fineness ...

Voltage Effect on the Optical Properties of Liquid Photonic Crystal Fiber

Voltage Effect on the Optical Properties of Liquid Photonic Crystal Fiber

The parametric performance of the photonic crystal fiber (PCF) infiltrated by LC 5CB is studied under the voltage variations. The COMSOL and MATLAB softwares have been used to study the performance of PCF under the variations of optical parameters including the effective refractive index, the normalized frequency, the effective mode area, numerical aperture and waveguide dispersion. Results indicated that both single-mode transmission and ultra-flat dispersion can be achieved under the ...

Effect of Precipitation Hardening on Deep Drawing of 6061 Al-Alloy

Effect of Precipitation Hardening on Deep Drawing of 6061 Al-Alloy

In this research, to investigate the effect of precipitation hardening on the deep drawing behavior of 6061 Al-alloy, first, the thickness of a 6061 Al-alloy sheet was decreased from 5 mm to 1 mm by four passes rolling and then, punched to obtain circular specimens with diameter of 80 mm. The specimens were heated in 528 deg;C for 60 min and then quenched in water and finally aged in 180 deg;C and 210 deg;C for 30, 120, 240, 360 and 480 min. After aging, they were quenched in water (25 deg;C). ...

Effect of the Medium Composition on Formation of Alpha Amylase by Bacillus licheniformis GMAF438149

A new medium was developed to induce high level of alpha;- amylase from Bacilluslicheniformis GMAF438149.The strain of Bacillus licheniformis was grown on the presence of different carbon , nitrogen and metal ions. The high level alpha;-amylase has been produced when potato starch and xylose were added to medium. Meat extract ,as an organic nitrogen source, had affected on enzyme yield , while inorganic sources were not found to be effective. Calcium chloride increased activity of the ...

The Effect of Priming on Seed Performance of Canola (Brassica napus L.) Under Drought Stress

Abstract: In order to investigate the effect of priming on canola seed performance under drought stress a studywas carried out at the Seed Research Laboratory of Razi University, Kermanshah, Iran. The experiment was afactorial with three factors arranged in a completely randomized design with three replications. The first factorwas seed priming (control (untreated), KNO and distilled water), the second was 3 drought stress levels (0.0, -0.3,-0.6, -0.9, -1.2 and -1.5 MPa) and the third was ...
