Background: The refining process generates large volumes of wastewater containing a variety of chemical contaminants. The use of natural substitutes in treating wastewater which have fewer harmful effects is considered an effective step towards protecting the environment and sustaining the development of these industries. This study focused on the use of Moringa oleifera and alum at t...

There are two ways of incorporating temporal distinctions into a system of logic: tensed theories propose to expand standard logic with intensional tense operators; tenseless theories try to make do with the resources of extensional first-order logic, by using quantification over suitably chosen temporal entities, such as metaphysically basic time points or temporal parts. My concern in this pa...

one of the causes of neonatal hyperbilirubinemia is increased reabsorption of bilirubin from meconium in the gastrointestinal tract. this occurs when the conjugated bilirubin which is excreted into the colon is 'unconjugated by beta glucuronidase activity, present in the neonatal intestine, which hydrolyzes bilirubin diglucuronide into unconjugated bilirubin, which subsequently is reabsorb...

Armed conflicts are as old humanity itself. In past, regular armies were not established. The individuals, ordinarily the adults of hostile tribes, used to participate in armed conflicts. However, participation children was also common certain situations. Although would have been active participants, they engaged a strategic tool and proved be most vulnerable segment such situation. With passag...

background: previous studies have shown that meconium staining of the amniotic fluid may affect maternal and neonatal outcomes. in this study, we aimed to investigate the relationship between birth weight and meconium passage and its related factors in pregnant women.materials and methods: this matched case control study was conducted on a total of 200 newborns (100 as cases and 100 as controls...

One-Fifth of the population of the world live in China. China is the biggest developing country in the world. China also has a higher biodiversity and is the most abundant World Natural and Cultural Heritage country, so Chinese environmental protection is very important to the globe. China is facing the crucial period of developing the economy and protecting the environment. At present in China...

The natural immune system is very e ective at protecting the body from diseases. Several researchers have analyzed the natural system and created arti cial systems which copy mechanisms of the natural system in order to improve computer security. We suggest that the negative selection algorithm, which is at work in the natural system, might have been copied too closely. We argue against the use...

Herein we report the first enantioselective total synthesis of (+)-dichroanone, confirming the absolute configuration of the natural product. This protecting group-free route features the first application of our enantioselective Tsuji allylation in the context of a natural product total synthesis. Additionally, this 11-step preparation of the molecule from commercial material features a novel ...
