T HE old-age and survivors insurance program combines three types of protection for workers and their families-retirement protection for those between the ages of 65 and 75, annuities for those aged 75 or over, and survivor insurance, payable on the death of an insured worker at any age. The retirement test (or work clause) is applicable when the beneficiary is under age 75, both for retirement...
among the main factors of friendly commercial and political relations between safavid iran and india were reciprocal needs and policies of safavid kings concerning trade development. thus, various regions of iran, especially isfahan, had became a good market for indian goods. isfahan as a capital of safavid state was a centre of commercial activities of such indians as baniyans, multanians, and...
Signature iii ABSTRACT This study was conducted to collect data about milk consumers in San Luis Obispo County. Surveys were created and administered to grocery store shoppers at five different cities in San Luis Obispo County. These surveys included questions about demographics, purchasing behavior, and desirability ratings. The data was inputted into a computer and then analyzed using Statist...
any change in the refractive index of a laser active medium can lead to serious degradation of beam quality, laser beam modes, laser performance and variation in the intensity distribution. alteration in the refractive index of laser active medium is especially notable in high power lasers. it is clear that in the laser beam production, the pumping agent induces a great amount of heat which...
Known as a Lewis acid which acts as a natural catalyst, bentonite can be used to produce several arylidene (thio) barbituric acid derivatives through conducting a Knoevenagel reaction between aromatic aldehydes and (thio) barbituric acid. Water is considered as the medium for this reaction and the results are at arange of good to excellent over a reasonable reaction time. This method i...
abstract ion selective electrodes (ises) are electrochemical sensors that respond selectivity to the activity of ionic species. an ion-selective electrode is an electrochemical device that uses a thin selective membrane or film as the recognition element, and is an electrochemical half-cell equivalent to other half-cells of the zeroth (inert metal in a redox electrolyte). in common methods o...
The C-C bond formation is an important reaction in organic synthesis to obtain value-added intermediates. Therefore, in this paper an attempt has been made to accelerate the Henry reaction (C-C bond formation) between aryl aldehydes and nitromethane using less expensive whole cell biocatalyst, baker’s yeast (BY). The scope of the methodology was also tested for the heteryl aldehyde i.e. 2-chlor...
Small changes in pressure or temperature, close to the critical point, lead to large changes in solubility of supercritical carbon dioxide (CO2). Environmentally friendly supercritical CO2 is the most popular and inexpensive solvent which has been used for preparation of nanodrugs and nanocarriers in drug delivery system with supercritical fluid technology. Delivery...
