Optimal average size

In this paper, curcumin nano-emulsions were successfully prepared by combining hominization and ultra-sonication methods which have been mentioned. The optimal conditions for the hominization method have been established as follows: 3% emulsifier concentration, 20,000 rpm of capacity in 60 minutes, the average size of nano drops was 78 nm.

The paper has developed an optimization procedure to design the rotor lamination and magnetic sizes. The average torque is improved by changing the thickness of the outer bridge and magnetic width. Various metamodels with the best prediction performance generated for each of the multiobjective functions and constraints have been selected.

Studying four species of red wood ants (Formica rufa, F. polyctena, F. aquilonia, F. lugubris), we examined nest morphometrics (height and diameter of anthills), spatial parameters (location of anthills of different sizes relative to each other), and the number of trails per colony in three regions of Ukraine and Russia: Kyiv region (877 anthills), the Urals (274 anthills) and Cis-Baikal (72 anthills). We have established a relationship between the number of anthills in the nest complex and the maximum parameters of the average height and diameter, as well as the average number of trails.

The catalyst 7.5% NiO/TiO2 and seven samples of NiO/γ-Al2O3 with NiO content from 7.5% to 60% have been obtained and studied. Physico-chemical characteristics of the catalysts were determined by methods of Adsorption (BET), X-ray Diffraction (XRD), TemperatureProgrammed Reduction (TPR) and Hydrogen Pulse Titration. The catalytic properties of the obtained samples were investigated in the reaction of CO methanation at temperatures 180 – 220◦C and mole ratios hydrogen/carbon monoxide 25-100.

Exact prediction of the cooling and heating load, proper sizing of the heat ventilation airconditioning (HVAC) system and optimal control of the HVAC systems are important to minimize energy consumption. Calculation of thermal load of building is very essential to find exact air-conditioning equipment and air handling unit, to achieve comfort operation and good air distribution in the air-conditioned zone. This project Cooling load estimation for a Reading Hall of CAET, JAU presents by using TETD method. The Reading Hall considered in this study is situated in Junagadh (70.45°E, 21.

The objective of present work was to utilize potential of nanostructured lipid carriers (NLCs) for improvement in oral bioavailability of raloxifene hydrochloride (RLX). RLX loaded NLCs were prepared by solvent diffusion method using glyceryl monostearate and Capmul MCM C8 as solid lipid and liquid lipid, respectively. A full 32 factorial design was utilized to study the effect of two independent parameters namely solid lipid to liquid lipid ratio and concentration of stabilizer on the entrapment efficiency of prepared NLCs.

This study was focused on the synthesis of silver nanoparticles using Acalypha hispida leaf extract and the characterization of the particles using UV–Vis spectroscopy, XRD, FT-IR, and TEM. The results showed the formation of silver nanoparticles, crystalline in nature, with an average size of 20–50 nm. The leaf extract components were analyzed with GC–MS and exhibited a high content of Phytol (40.52%), n-Hexadecanoic acid (9.67%), 1,2,3-Benzenetriol (7.04%), a-D-Mannofuranoside methyl (6.22%), and D-Allose (4.45%).

In this paper, we discussed the effects of discount price on demand and profit in a diminishing market. A production plan has been suggested for an imperfect production system. Here, demand is considered to be price sensitive and negative power function of the selling price. This problem is solved by optimization, using the Hessian matrix of order three. The main objective is to find the optimal excepted average profit, optimal selling price, discount rate, backorder level, and lot-size. The recommendations are provided to offer a price discount for limited sale season on different occasions.

There is a global trend of falling household sizes over time, though an international comparison quickly reveals that this reduction is not uniform across countries. Apart from tradition, economic variables are influential in determining how many people live together in one household. We have tried to capture this relationship with a pooled cross-section of 38 countries and data for different years between 1960 and 2006. The dependent variable is the average household size.
