Antithrombin (AT) is a glycoprotein that inactivates the several physiological target enzymes of coagulation system. The effect of purification strategies plays a crucial role in getting maximum recovery of yield, purity and biological activity of recombinant human antithrombin (rhAT). In the present work, the task of purifying rhAT from Saccharomyces cerevisiae BY4741 has been carried out usin...

This paper addresses the problem of determining the sale price and the production quantity under supply uncertainty. The problem is commonly observed in the agricultural industry. We consider a firm that initially leases farm space in order to grow fruit. The realized amount of fruit supply fluctuates due to weather conditions, diseases, etc. At the end of the growing season, the firm makes two...

background: 66ga (t1/2=9.49 h, β+: 4.153 mev, γ: 511, 834, 1039, 2752 kev) has a wide range of applications in different fields of medical sciences. production of 66ga became one of our main interests, according to its increasing applications in nuclear medicine, particularly in pet imaging. materials and methods: 66 zn (p,n)66ga reaction was determined as the best choice for the production of ...

growing applications of phenylalanine dehydrogenase (phedh) enzyme in the medical and pharmaceutical industries encourages researchers to seek simple, fast and economical alternative purification methods. with goal of finding a new technique, the extraction and purification of recombinant bacillus badius phedh in polyethylene glycol 6000 (peg-6000) and ammonium sulfate aqueous two-phase systems...

Our work solves the problem of inventory tracking in the retail industry using Hidden Markov Models. It has been observed that inventory records are extremely inaccurate in practice (cf. [1–4]). Reasons for this inaccuracy are item losses due to item theft, mishandling, etc. which are unaccounted. Even more important are the lost sales due to lack of items on the shelf, called stockout losses. ...

grain discoloration caused by fungi agents, in crop season that the mature grain stage coincides with rain, it causes many damages. in this research effect of paddy discoloration of three varieties (hashemi, gohar and khazar) and disease index in two levels (high and low disease index levels) on grain apparent quality, milling properties and grain bending strength was investigated in a factoria...
