This thesis describes methods to obtain value–added compounds from TMPturpentine obtained from the spruce, Picea abies. The methodology focuses on biotransformations using two approaches: an oxygenation approach (i.e. oxygenation of terpene hydrocarbons by cell cultures) and an esterification approach (i.e. lipase-catalysed transesterification of vinyl acetate with terpene alcohols, and a furth...

During our screening program for agrochemicals from Chinese medicinal herbs and wild plants, the essential oil of Carum carvi fruits was found to possess strong contact toxicity against Sitophilus zeamais and Tribolium castaneum adults, with LD₅₀ values of 3.07 and 3.29 μg/adult, respectively, and also showed strong fumigant toxicity against the two grain storage insects with LC₅₀ values of 3.3...

During human infection, Mycobacterium tuberculosis (Mtb) survives the normally bacteriocidal phagosome of macrophages. Mtb and related species may be able to combat this harsh acidic environment which contains reactive oxygen species due to the mycobacterial genomes encoding a large number of dehydrogenases. Typically, dehydrogenase cofactor binding sites are open to solvent, which allows NAD/N...

‎Let $p(z)$ be a polynomial of degree $n$ and for a complex number $alpha$‎, ‎let $D_{alpha}p(z)=np(z)+(alpha-z)p'(z)$ denote the polar derivative of the polynomial p(z) with respect to $alpha$‎. ‎Dewan et al proved‎ ‎that if $p(z)$ has all its zeros in $|z| leq k, (kleq‎ ‎1),$ with $s$-fold zeros at the origin then for every‎ ‎$alphainmathbb{C}$ with $|alpha|geq k$‎, ‎begin{align*}‎ ‎max_{|z|=...

چکیده در این پایان نامه به بررسی شرایط کافی برای قویا ستاره گون بودن توابع p- ارزاز مرتبه ی ?و از نوع ? درuپرداخته و داریم: فرض کنیم a_pکلاس نگاشت های f(z) به شکل f(z)=z^p+?_(n=1)^???a_(p+n) z^(p+n) ? (p?n={1,2,3,…}) که هر کدام روی دیسک واحد بازu={z:|z|<1} تحلیلی هستند، باشد.تابع f(z)?a_p را ستاره گون p- ارز از مرتبه ی ?می گوییم هر گاه برای هر ??[0,1) و هر z?u داشته باشیم: re((zf^ (z))/f(...
