Abstract The chlorine and total trihalomethane (TTHM) concentrations are sparsely measured in the trunk network of Bogotá, Colombia, which leads to a high uncertainty level at an operational level. For this reason, research assessed prediction accuracy for TTHM two black-box models based on following artificial intelligence techniques: neural networks (ANNs) adaptive neuro-fuzzy inference syste...
data envelopment analysis (dea) is a powerful tool for measuring relative efficiency of organizational units referred to as decision making units (dmus). in most cases dmus have network structures with internal linking activities. traditional dea models, however, consider dmus as black boxes with no regard to their linking activities and therefore do not provide decision makers with the reasons...
هدف از این پژوهش بهبود گوارش پذیری سورگوم دانه ای با کاهش تانن سورگوم دانه ای و جیره نویسی به روش استاندارد آمینواسیدهای گوارش پذیر در جوجه های گوشتی cobb 500)) بر پایه سورگوم دانه ای و بررسی اثر جیره ها بر عملکرد، گوارشپذیری مواد خوراکی، وزن نسبی اندام ها و لاشه بود. در آغاز هفته ی دوم دوره پرورش، تعداد 320 قطعه جوجه ی به 8 تیمار (هر تیمار دارای 4 تکرار و هر تکرار دارای 10 قطعه جوجه) دسته بند...
background: in the recent years, eutrophication has become a serious challenge for many of the water ecosystems. it has affected the environmental and economical aspects of the anzali wetland, which is known as one of the significant ecosystem. due to the increase of the nutrient loadings from the industrial, agricultural and human activities, the wetland’s health is faced many serious problems...
present transplant study was carried out across lucknow, the capital of utter pardesh using two medicinally important plants viz., ?catharanthus roseus l.? and ?ocimum sanctum l.? to assess whether certain ecophysiological responses (change in total flavonoids and total phenolics) in these two plants may serve as the biomarkers of auto exhaust pollution. samples were taken from five different s...
hedging is a multi-purpose rhetorical strategy which is usually used in scientific arguments to secure ratification of claims, reduce the risk of negation, avoid conflict, manage disagreement and leave room for the audience to assess presented information. hedges are frequently used in research articles to mitigate the findings of research endeavors. the present research aims to investigate the...
چکیده پژوهش انسان بالغ در24 ساعت به حدود 2400 کیلوکالری انرژی نیاز دارد.بدن این انرژی راازسوزاندن مواد غذایی اصلی همچون چربی ها پروتئین هاوهیدراتهای کربن تامین می نماید.این میزان انرژی موردنیاز باپارامترهایی چون سن،جنس بیماریهاوشرایط مختلف فیزیولوژیک تغییرمی کند . بیهوشی یکی ازعواملی است که این میزان نیازراتغییرمیدهد.دراین پایان نامه سعی شده است اصول تغذیه کامل ازراه تزریقی دربیهوشیهای مختلف ،د...
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, ...
