A novel intramolecular Prins type cyclisation of cyclopropylvinylic aldehydes promoted by TiCl(4) under mild reaction conditions to form cis-cyclic products in high yields has been accomplished.
A large database of invasive forest pathogens (IFPs) was developed to investigate the patterns and determinants of invasion in Europe. Detailed taxonomic and biological information on the invasive species was combined with country-specific data on land use, climate, and the time since invasion to identify the determinants of invasiveness, and to differentiate the class of environments which sha...
This study was conducted to determine the chemical composition, digestibility, degradability and nutritive value of madder, Rubia tinctorum L. and alfalfa Medicago sativa. using in vitro and in situ measurements. The mean values for OM, CP, NDF, ADF and EE were 892.5, 172.0, 306.5, 219.4 and 16.0 g/kg DM for madder hay, and 921.3, 141.4, 482.0, 361.1 and 6.50 g/kg DM for alfalfa hay, respectiv...
Lymphoepithelial - like carcinoma, is rarely recognized in the urinary bladder and less commonly occurs with papillary transitional cell carcinoma i.e. mixed pattern. Also, less uncommon is the occurrence of carcinoma in situ changes in the adjacent urothelium of these tumors. Here, a case of lymphoepithelial – like carcinoma and papillary transitional cell carcinoma associated with carci...
The aim of this study was to determine and compare in situ biohydrogenation (BH) fatty acids in three forms of soybeans and linseed (raw, extruded and roasted). Nylon bags (5×10 cm) containing 4 g of raw, extruded or roasted soybeans or raw, extruded or roasted linseed were incubated in the rumen of fistulated ewes for 4, 8, 12 and 24 hours. Results for linoleic acid (C18:2) showed tha...
Despite the great potential of graphene as a nanofiller, achieving homogeneous dispersion remains the key challenge for effectively reinforcing polyolefin (such as polyethylene (PE) and polypropylene (PP)) nanocomposites. Therefore, in this research, we report a facile combined in situ polymerization and masterbatch method for fabricating PP/reduced graphene oxide (rGO) nanocomposites. In the p...
abstract since for some reasons such as studying the behaviour of old construction materials and proper replacement of the deteriorated sections, adequate knowledge about the true in situ strength of the construction materials has become a necessity, many attempts have been made to invent and develop new in situ methods in recent years. most of these methods measure the in situ strengths of mat...
In situ activation of a Ni catalyst with Mo ion for hydrogen evolution reaction in alkaline solution
In this study Ni catalyst have been activated during hydrogen evolution reaction (HER) by adding Mo ions into the alkaline electrolyte. After dissolving different amounts of ammonium molybdate in the 1M NaOH as electrolyte, Ni catalyst was used as cathode for HER. Afterwards a comparison between hydrogen overpotential measured in Ni catalyst with and without in situ activation has been made; th...
This study was aimed to evaluate the correlation between in vitro fermentation and in situ degradation parameters and to predict dry matter degradability and energy protein synchronization of roughage based diets. Different inclusion of roughage in diets [roughage 50% diet (R50D), roughage 60% diet (R60D), roughage 65% diet (R65D) and roughage ...
Background and Objective: Since the advent of mammography screening, ductal carcinoma in situ (DCIS) of the breast has been diagnosed increasingly. In contrast to the situation in invasive breast carcinoma, there are only a few reports on androgen receptor (AR) status in DCIS and few reports on estrogen ...
