Abstract:
Light pollution is a worldwide problem that affects fewer stars that can be seen at night. This study aims to measure the brightness of the sky in the zenith direction to minimize the effect of light pollution in observing celestial bodies. The research used the observation method of sky brightness level with SQM. Measurement of sky brightness was carried out in two places, namely in Medan and Serdang Bedagai. The SQM is mounted in a zenith direction and set to retrieve data every two seconds. Observations were made on November 10-13, 2018, during the new moon phase. The average value of sky b

Abstract:
A total lunar eclipse plausibly has an influence on the variation of some environmental physical parameters, specifically on the conditions of the sky brightness, humidity and temperature. During the eclipse on 14th - 15th April 2014, these parameters were measured with a photometer and a weather station. The obtained results allow the comparison, practically, of the optimal conditions for observational astronomy work in the Tatacoa desert and, therefore, to certify it as suitable place to develop night sky astronomical observations.

The widespread use of artificial light at night has improved the quality of human life, but it has also brought about a global light pollution problem with profound and complex ecological, human and economic impacts. To measure the severity of light pollution, a new light pollution risk index was developed in this paper. Three main aspects of light pollution impacts were considered: economic level (EL1), ecological level (EL2) and social level (SL), and six tertiary levels were identified under the secondary evaluation indicators.

Acetic acid promotes the reduction of aldehydes and ketones by the readily available N-heterocyclic carbene borane, 1,3-dimethylimidazol-2-ylidene borane. Aldehydes are reduced over 1–24 h at room temperature with 1 equiv of acetic acid and 0.5 equiv of the NHC-borane. Ketone reductions are slower but can be accelerated by using 5 equiv of acetic acid. Aldehydes can be selectively reduced in the presence of ketones. On a small scale, products are isolated by evaporation of the reaction mixture and direct chromatography.

Metals in borate lacked intrinsic catalytic activity for propane conversion; instead, they modulated [BO3]3− group reactivity through adjustments in electron density.

Abstract:
In this study, the evaluation of interfaces on iron boride Fe2B growth obtained by paste boriding process was carried out. Fractal geometry is used like a powerful tool for the roughness analysis present during iron boride growth. Experiments were performed in AISI 1045 steel at temperatures of 1193K for exposure times of 2, 4 and 6 h, and 1223K for treatment times of 2, 4, 5 and 6 h, varying the boron paste thicknesses in the range of 1 – 5 mm for each temperature and time. The fronts of the interfaces in iron boride coatings were characterized and digitized with mean of an optic microscope a

Abstract:
Novel hexafluoroisopropylboranes (CF3)(CF2H)CFBH2·L and -borate anions [(CF3)(CF2H)CFBH2X]− with Lewis basic heterocyclic ligands L and the anionic substituents X = F− and CN− were obtained. The syntheses were accomplished by substitution reactions of the dimethyl sulfide adduct (CF3)(CF2H)CFBH2·SMe2, which was synthesized on a large scale. The hexafluoroisopropylboranes and -borates were characterized by NMR and vibrational spectroscopy, elemental analysis, and single-crystal X-ray diffraction. In addition, the thermal and electrochemical stabilities were investigated by DSC measurements and

Abstract:
Neglected and underutilized species (NUS) offer largely unexplored opportunities for providing nutritious plant food, while making agro-ecosystems more diverse and resilient to climate change. The aim of this work was to explore the potential of two typical Mediterranean underutilized species, purslane and borage, as novel vegetable product (microgreens). Micro-scale production of edible plants is spreading due to the simplicity of their management, rapid cycle, harvest index, and phytochemical value of the edible product. Microgreens, therefore, represent an opportunity to link NUS, nutrition

Abstract:
Glass fiber is commonly used as thermal insulation for the equipment in nuclear power plants. In case of LOCA (Loss Of Coolant Accident), the insulation can be damaged by the jet impact and carried to the screens of the emergency systems needed to cool the reactor. In this case, the fibers can be strongly corroded by particular cooler solutions and their behavior under this environment can modify the head loss of the screens. The pH value of coolant solution can be stabilized respectively by borate or phosphate buffering systems depending of the plants. A new type of small scale laboratory equ

Do consumers prefer certain combinations of edible-flower species and colors over other assortments? Two hundred and sixteen people were self-selected for a survey at a Michigan flower show to rate 15 photographs of edible flowers arranged in 0.24-L, clear, plastic containers. Each container had either an individual species or combinations of Viola tricolor L. `Helen Mount' (viola), Borago officinalis L. (borage), and Tropaeolum majus L. `Jewel Mix' and `Tip Top Apricot' (nasturtium). To determine what color(s) of nasturtium participants would prefer, containers held either orange and crimson,

Abstract:
New organic nanostructures were synthesized by introducing 2-methylbenzimidazole (MBI) molecules from a melt, gas phase, or alcoholic solution into nanosized voids of borate porous glasses (PG), nanotubes of chrysotile asbestos (ChA), and mesoporous silica (MS). The incorporation of MBI into borate glasses with different pore sizes is accompanied by the appearance of several phases formed by nanocrystallites which have a MBI crystal structure, but somewhat differ in lattice parameters. The size of some crystallites significantly exceeds the size of nanopores, which indicates the presence of lo

Since then, 68 ZIKV positive cases have been reported from Kerala, with majority of cases from Thiruvananthapuram Corporation area. Based on the preliminary investigation, micro containment zones were identified and detailed investigation was carried out in these areas. Entomological surveillance indicated that all the three species of Aedes mosquitoes - Ae. aegypti, Ae. albopictus and Ae. vittatus were present in the survey areas. The Aedes larval indices were found above the critical level. T
