Determining the seasonal and annual quantities and compositions of the municipal solid waste and assessing the present management conditions of three urban communities in the northwest of Iran were the core objectives of this study. Our findings revealed that the average daily per capita of municipal waste generation was 0.489–0.841 kg/cap-day. Organic and food waste comprised the largest part ...
This study was carried out to determine the effects of acetic acid, hot water, and cold sand stratification scarification at different periods on seed germination carob (Ceratonia siliqua L.) in Salah Alden province. The seeds were collected from Kirkuk province area September 2016. Carob stratified not treated by soaking glacial acid for 20, 40, 60, 120 min. lab temperature (25oC). Hot water (...
.soil microorganisms are important agents in nutrient cycling and energy flow. they are extremely sensitive to environmental changes. soil microbial biomass has been proposed as an index of soil stress and disturbance. the objective of this study was to determine the effects of barley (hordeum vulgare l.) residue amounts, burning, nitrogen fertilizer levels and tillage management on organic car...
Let $G=(V(G),E(G))$ be a graph, $gamma_t(G)$. Let $ooir(G)$ be the total domination and OO-irredundance number of $G$, respectively. A total dominating set $S$ of $G$ is called a $textit{total perfect code}$ if every vertex in $V(G)$ is adjacent to exactly one vertex of $S$. In this paper, we show that if $G$ has a total perfect code, then $gamma_t(G)=ooir(G)$. As a consequence, ...
I. A machine is described which automatically releases previously weighed rations to individually penned sheep at hourly intervals for 24 h. 2. Six sheep were kept in a room with constant light, temperature and continuous background noise and given 91 2 g lucerne daily at 10.00 h or at hourly intervals by means of the automatic feeder. Faeces and urine were collected every 2 h. 3. Hourly feedin...
Abstract Background and purpose: Eutrophication is one of the major environmental problems in waterways causing substantial adverse impact on domestic, livestock and recreational use of water resources. Aras Dam, Iran which provides Arasful city with drinking water, has chronic algal blooms since 1990. Levels of up to 900,000 cells/mL of toxic cyanobacteria (mainly Anabaena and Microcystis) hav...

OBJECTIVE Abnormalities in frontal lobe phosphorous metabolism in patients with bipolar disorder have been reported, but many of the patients studied were receiving lithium. In this study, medication-free bipolar patients were examined to determine abnormalities in frontal lobe high-energy phosphorous metabolism. METHOD In vivo phosphorous-31 magnetic resonance spectroscopic imaging was perfo...
1. to determine whether difference in birth body mass influenced growth performance in pipistrellus kuhlii we studied a total of 12 captive-born neonates. bats were assigned to two body mass groups: light birth body mass (lbw: 0.89 ± 0.05, n=8) and heavy birth body mass (hbw: 1.35 ± 0.08, n=4). heavier body mass at birth was associated with rapid postnatal growth (body mass and forearm length) ...
