The effects of aeration through lid filters on the hyphal growth of Lentinula edodes (oak mushroom) in sawdust cultivation bags were investigated. The aeration treatment levels were traditional 27 mm hole cotton plugs, cotton balls and combinations of seven hole sizes × two hole positions (up and under) in the lids covering plastic bags containing 1.4 kg sawdust medium at 63% moisture that had ...

Background:Extrauterine growth restriction remains a common and serious problem in newborns especially who are small, immature, and critically ill. Very low birth weight infants (VLBW) had 97% and 40% growth failure at 36 weeks and 18-22 months post-conceptual age respectively. The postnatal development of premature infants is critically dependent on an adequate nutritional intake that mimics a...

The goal of this study is to show the usefulness of reinforcement learning (RL) to solve a common greenhouse climate optimisation problem. The problem is to minimise the daily heating cost while achieving simultaneously two agronomic goals, namely maintaining a good crop growth and an appropriate development rate. The complexity of the problem is due to the very different time constants of thes...

The purpose of this study was to determine the effect different feeding on survival rate and growth snakehead fish (Channa striata) larvae. This research conducted using a completely randomized design (CRD) with 3 treatments replications. treatment consisted A artificial PF 0, B Daphnia C silk worms. results showed that provision types feed had significant survival, absolute weight growth, dail...

Glucose-dependent growth of the luxCDABE reporter bacterium Pseudomonas fluorescens HK44 was monitored noninvasively in quartz sand under unsaturated-flow conditions within a 45- by 56- by 1-cm two-dimensional light transmission chamber. The spatial and temporal development of growth were mapped daily over 7 days by quantifying salicylate-induced bioluminescence. A nonlinear model relating the ...

artemia plays a major role in aquaculture as one of the most important live foods used in larval rearing. the aim of this study was to determine the optimum level of feeding in artemia urmiana with baker's yeast (saccharomyces cerevisiae). triplicate groups were fed with different levels of s. cerevisiae yeast 0.625 (control), 1.25 (t1), 2.50 (t2), 5.0 (t3) (mg yeast per 1000 nauplii) for ...

present study examines whether there is any beneficial effect of magnetized water application on seedling emergence of maize seeds. water from various sources like tap water, saline water (1,500 ppm), canal water, and sewerage water was treated magnetically by passing it through 235 mt magnetic fields at 3 lpm flow rate. seeds were soaked in water for 24 hours and planted in sand culture. numbe...

A useful approach to monitor tree response to climate change and environmental extremes is the recording of long-term time series of stem radial variations obtained with precision dendrometers. Here, we study the impact of environmental stress on seasonal growth dynamics and productivity of yellow birch (Betula alleghaniensis Britton) and sugar maple (Acer saccharum Marsh.) in the Great Lakes, ...

Studies were conducted to determine the effects of high dietary ascorbic acid (vitamin C) on growth performance and body composition of a commercially important Asian catfish, Clarias batrachus. During experimental trial in the laboratory condition, the change in growth and feed utilization by the Clarias batrachus fed on three different Vitamin C level have been assessed by the determination o...
