Oxo-homoscorpionate borate ligand, potassium bis(phthalato)borate (KL) has been synthesized as its potassium salt. It was converted into its Co(II), Ni(II) and Cu(II) dinuclear complexes by mixing and stirring with methanol solution of metal chloride. The compositions of ligand and its metal complexes were investigated by elemental analysis in order to ensure their purity and the structural elu...

Introduction: Dust is one of the significant factors which cause occupational respiratory diseases among workers. Objective: The main purpose of this study was to determine the dust concentration, its silica percentage and comparison with standard. Method: This cross-sectional study was carried out at one of iron-stone ores in Southern Khorasan province. Air dust sampling was done using the NIO...

The tremendous therapeutic potential of curcumin as a chemopreventive, antineoplastic and chemosensitizing agent has failed to progress towards clinical development and commercialization due to its unfavorable physicochemical properties, low aqueous solubility, chemical instability, and pharmacokinetics. The present contribution is focused on the feasibility of using PEGylated calixarene, in pa...

Abstract The synthesized biochars derived from sawdust (SD) SD ozone (SDO) biochar, purified (PSD) and sonicated (SSD) which was employed in the confiscation of methylene blue (MB) dye ion, were characterized employing “Brunauer–Emmett–Teller (BET), scanning electron microscope (SEM), Fourier Transform Infrared (FTIR), Thermal gravimetrical analysis (TGA).” impact various factors, such as pH, b...

The market for mats and blankets made from natural fibers is a rapidly growing segment of the erosion control industry. In south Louisiana, bagasse is a local, readily available material with properties that make it suitable for erosion control products. In the framework of work towards diversifying the sugarcane industry, a prototype of a simple continuous device to produce erosion control mat...

BACKGROUND The start-up behavior of syringe and syringe pump is known to be one of the causes of inaccurate intravenous infusion. This study evaluated the method of priming the infusion system (PRIMING), and its impact on the target-controlled infusion (TCI) of two remifentanil diluents. METHODS PRIMING was performed using an evacuation of 2.0 ml to the atmosphere prior to TCI. Forty-eight TC...

Both the hardening process and formation of microstructure of concrete are significantly influenced by the curing condition. The capillary absorption of concrete is closely related to the structure and distribution of the pores within the material. This paper presents an experimental study on the influence of four curing conditions, i.e., standard curing, natural curing, water curing, and seale...

This paper reports on the indoor and outdoor air quality in informal urban rural settlements Kenya. The study is motivated by need to improve consciousness understand harmful health effects of vulnerable people, especially poor communities. Ng’ando settlement Leshau Pondo village Kenya are selected as representative neighborhoods where unclean energy sources used for cooking, lighting heating. ...

Online-characterization of carbonaceous nanoscaled particles is important in different application fields, e.g., in carbon black production or in automobile raw exhaust. For the determination of mass concentration and primary particle size respectively specific surface area, a possible in situ measurement technique is time-resolved laser-induced incandescence (TIRE-LII). The basic principle of ...
