研究了黄腐酸(FA)作为一种的新的络合剂,与羟丙基-β-环糊精络合物(Hp-β-CD)相比,对阿司匹林(ASA)分解的影响。ASA与FA以1:0.5、1:1、1:2(物质的量比)络合,并用冷冻干燥、溶剂蒸发和喷雾干燥三种方法进行干燥。ASA-羟丙基-β-环糊精(1:1)络合物通过喷雾干燥制备,并与最佳FA络合物进行比较。将所有的络合物和ASA放入贴好标签的铝塑小包中密封,在温度为40±2℃、相对湿度为75%±5%的稳定暗箱中存放120d。分别在0、30d、60d、90d和120d分析各样品的水杨酸含量。以物质的量比为1:1进行络合的ASA-FA喷雾干燥络合物中水杨酸含量为4.31%,该络合物在所有不同制备方法的络合物中具有最佳稳定性。然而,1:1的ASA-羟丙基-β-环糊精喷雾干燥络合物中测得水杨酸含量只有2.35%。与FA相比,ASA与羟丙基-β-环糊精络合,其稳定性更强。为提高阿司匹林的稳定性,对一种新型FA络合剂进行了研究。与1:1ASA-FA喷雾干燥络合物相比,ASA与羟丙基-β-环糊精1:1络合时,ASA的稳定性有显著改善。

Pigmentation plays important adaptation and physiological efficiency roles in animals. In the sequence of a 648 bp fragment representing intron 1, exon 2, and part of intron 2 of the MLPH mammalian pigmentation gene, we identified a novel g.469C> G mutation in intron 2, and genotyped it in 266 Nigerian goats using PCR-RFLP analysis. The C allele had frequencies of 0.9625, 0.9804 and 0.97405 in West African Dwarf (WAD),Sahel(SH) and Red Sokoto (RS) breeds, respectively. The G allele was the highest in WAD (0.0375), followed by RS (0.02595), and then SH (0.0196). Overall low FIS and FST and high Nm values demonstrate little differentiation within and among the goat breeds at this intronic locus. This g.469C> G polymorphism in MLPH gene is the first in any goat breed and also first in Nigerian goats. Our results suggest that this intronic SNP locus is maintained at Hardy-Weinberg equilibrium (P < 0.05) and the lack of association of this SNP with coat color may indicate its neutrality in goats.

里奥—德雷(Rio del Rey)盆地位于喀麦隆境内、尼日尔三角洲(Niger Delta)东北缘,油气资源十分丰富,已有30余年油气勘探开发历史。古新世以来发生的长期海退和三角洲沉积作用,形成了现今的里奥—德雷被动大陆边缘盆地,其主要发育3个地层单元,自下而上分别为阿卡塔(Akata)组、阿格巴达(Agbada)组和贝宁(Benin)组。在三角洲进积推进过程中,由于大陆边缘的重力作用和三角洲泥岩的塑性推覆作用,由陆向海、自北向南形成了3个构造区,即伸展构造区、泥岩底辟构造区和逆冲推覆构造区。其中,在泥岩底辟构造区形成了许多与泥岩底辟或泥岩脊相关的辟顶背斜、断背斜构造圈闭或辟边岩性遮挡圈闭,现今已发现的大型油气田主要与这些圈闭有关。同时,泥岩底辟的活动也形成了储集和运移方面的优势条件,促使油气在泥岩底辟构造区富集高产。因此,未来泥岩底辟构造区以及与泥岩底辟相关的圈闭仍然是里奥—德雷盆地进一步寻找勘探潜力的主要地区。

This paper aims to explore past researches that examine the relationship between corporate social responsibility (CSR) and financial performance. The researcher intends to conduct researches that examine the relationship between CSR and financial performance in Iraq corporations. This paper highlights review of literatures from various countries that examine relationships between CSR with financial performance. This paper is based on secondary sources which are accumulated from many researches in Malaysia, Australia, UK, Indonesia, Sri Lanka, Nigerian, and Jordan. The study uses information generated from literature reviewed from different researchers relating to the topic. This method was applied by collecting information from journals and online sources relating to the issue under consideration. Regression analysis documents significant evidence to support a positive relationship between CSR and financial performance. Evidence suggests that CSR leads to good financial performance in Iraq corporations. Findings based on the review revealed that researchers also showed that there was a significant positive relationship between CSR practice and financial performance in Iraq corporations. This study focuses on disclosures made in the corporate annual reports. This is because the annual report is the common document produced by companies on a regular basis and is widely used in prior studies related to CSR. The study provides some important insights for our understanding of CSR in developing economies and its effects on financial performance in the context of Iraq companies.
