ABSTRACT: The effect of the pre-selection of particle size range on the treatment of locally-sourced bentonite clay from logomani, North-Eastern Nigeria using aqueous acid and alkali solution has been studied. Characterization of the clay adsorbents was done via Fourier Transform Infrared Spectroscopy (FTIR) and X-ray diffraction analyses (XRD). The acid and alkali modified clay adsorbents were applied in the removal of methylene blue from aqueous media. The highest adsorbed amount (51.196mg/g) which represents 91.421% for the HCl-treated clay was obtained with the clay particle size range of < 63µm treated with 0.5M HCl. While on the other hand, the lowest adsorbed amount of 24.726mg/g which represents 44.154% for the HCl-treated clay was obtained with the clay particle size range of 106-125µm treated with 2.5M HCl. A similar trend was also observed for the H2SO4-treated clay in which case the highest value of Qt (42.636mg/g)which represents 76.137% was obtained with particl...

ABSTRACT: Because of the scarcity of water resources and serious environment, it becomes much more emergence to develop the water saving agriculture. Drip irrigation and straw mulch both at home and abroad were wide studied. However, How to utilize saline water reasonably, scientificly, efficiently and safely has always been a core problem in farmland irrigation using saline water. Based on the relative research about salinity water irrigation, this paper studied on the effect of different salinity water irrigation and soil salt contents on maize growth in a plastic bucket experiment in Yonggu village, Ningxia shizuishan city of Ningxia located in Yellow River Irrigation district. The main results are as follows, showed that the salinity water had much greater effect on maize emergence rate than that of soil initial salt content. With the increase of irrigation water salinity and soil initial salt content, the maize height all decreased. Under the same soil saline content, the m...

ABSTRACT: The mixed Schiff base ligand, N,N′-o-phenylenebis(salicylideneimine) (H2salen) with the ligands 4- aminoantipyrine (AAP) or ammonium pyrrolidinedithiocarbamate (APDC) were reacted with Ni(II), Cu(II) and Co(II) acetates. Four new different complexes were prepared and formulated as [Ni2(salen)(CH3CO2)2(AAP)2] (1), [Ni2(salen)(CH3CO2)2(PDCH)2]·2H2O (2), [Cu2(salen)(CH3CO2)2]·2H2O (3) and [Co(salen)(CH3CO2)]·(H2O) (4). The H2salen ligand and its complexes were characterized by IR, UV-visible, TG, elemental analyses, and molar conductivities. The complexes were proposed to be distorted octahedral geometry with Ni(II) and Co(III) and distorted square planar geometry with Cu(II). Antibacterial activity of the complexes was tested against selected bacteria by agar well diffusion method.

ABSTRACT: Security assessment with vulnerability is based on American Petroleum Institute (API) Standard 780 Security Risk Assessment (SRA) Methodology which gives fixed steps combining with vulnerability, As Low As Reasonably Practicable, Swiss Cheese Model and cost-effectiveness theory. Vulnerability of different periods were analyzed emphatically, such as vulnerability before accidents, vulnerability in accidents and vulnerability after accidents. As Low As Reasonably Practicable can allow managers to know clearly that which assets should be protected deeply. Swiss Cheese Model helps analyzers understand detailed reasons of attacks and avoid adversaries’ attacks. Through cost-effectiveness theory, benefits of the security investments can be maximized. Overall, this article can make managers know more about the risk level in multiple dimensions and enlighten analyzers to assess the risk level of chemical plants.

ABSTRACT: In recent years the increased incidence of candidal infection is observed in the world, among them candidiasis takes the leading place. Candidiasis is an infectious disease caused by yeast-like fungi of Candida genus. There are both mild forms of this disease – candidiasis of the skin and mucous membranes and very severe forms – generalized candidiasis of visceral organs. In order to fight candidiasis the authors have developed an immunobiological drug for prevention and treatment of candidal infection. The drug contains antigens of C. albicans and C. tropicalis fungi with the total protein concentration of 4 mg/ml. The composition of the drug also includes the solvent phosphate buffer solution with рН 7.2 ± 0.2 and the preservative phenol in the conce ntration of 0.25 %. The drug developed possesses the protective and therapeutic effect. The aim of this work was to study toxicity of the immunobiological drug. The abnormal toxicity of the solution of the immunobiologic...

ABSTRACT: The P-sets ( ) F F A , A is introduced to study the dynamic characteristics of the set better. The packet sets ( ) F F A , A is a collection of sets which is composed of the internal packet set F X and the outer packet set F X ; in this paper, we not only introduce the attribute value matrices in the finite case, but also illustrate the relationship between the attribute value matrices and the packet sets. Finally we give the algorithm and examples using the attribute value matrices for the P-sets.

ABSTRACT: Cinnamon oil has been confirmed as a useful antifungal agent to inhibit Rhizopus nigricans. However, the antifungal mechanism has not been clearly revealed. The possible mechanism as follows were investigated, such as the effects of cinnamon oil on the cell morphology, cell membrane and the activities of the key enzymes in tricarboxylic acid (TCA) cycle. Cinnamon oil can inhibit the mycelia growth of R. nigricans, and scanning electron microscope (SEM) observations revealed that the mycelia morphology alterations of R. nigricans were the markedly shriveled and collapsed hypha, even flatted empty hyphae, swelled cell wall, disrupted plasma membrane, with cytoplasmic matrix leakage. Furthermore, cinnamon oil inhibited the biosynthesis of ergosterol significantly, damaging the cell membrane structure, causing the leakage of intracellular ions, protein and the higher absorbance at 260nm. Moreover, cinnamon oil affected the energy metabolism of R. nigricans by decreasing th...
