Cyclopentadienyl-titanium complexes containing –OC6H4X ligands (X = Cl, CH3) activated with methylaluminoxane (MAO) were used in the homo-polymerization of ethylene, propylene, 1-butene, 1-pentene, 1-butene, and 1-hexene, and also in copolymerization of ethylene with the α-olefins mentioned. The -X substituents exhibit different electron donor-acceptor properties, which is described by Hammett’...

The mono-epoxidation of geraniol by dimethyldioxirane was carried out in various solvents. In all cases, the product ratios for the 2,3 and 6,7 mono-epoxides were in agreement with literature values. Kinetic studies were carried out at 23 degrees C in the following dried solvent systems: acetone (k(2) = 1.49 M(-1)s(-1)), carbon tetrachloride/acetone(9/1, k(2)=2.19 M(-1)s(-1)), and methanol/acet...

Selective reagent ionization time-of-flight mass spectrometry with NO(+) as the reagent ion (SRI-TOF-MS (NO(+))) was applied for near real-time monitoring of selected skin-borne constituents which are potential markers of human presence. The experimental protocol involved a group of 10 healthy volunteers enclosed in a body plethysmography chamber mimicking the entrapment environment. A total of...

The mechanical behaviour of a new type of open-cell foam made by a thermally induced phase separation (TIPS) process was investigated. Foams made by the TIPS process are characterized by cell sizes which are 10-100 times smaller than conventional foam materials. In this work, the linear elastic modulus of these foams in dynamic tension/compression was measured. A comparison was made with the th...

In this work, the role of the disulfide bridges in the maintenance of the secondary structure of the antimicrobial peptides androctonin, polyphemusin-I, and thanatin is analyzed on the basis of their structural characteristics and of three of their respective mutants, andry4, poly4, and thany2, in which all the cysteine residues have been replaced with tyrosine residues. The absence of the disu...

Background and Purpose: Soleshine is a polyherbal preparation established in the market for the treatment of cracks and tinea pedis, which is applied externally. This preparation is composed of the extracts of indigenous plants, namely Azadirachta indica, Lawsonia alba, and Shorea robusta, mixed with castor oil and sesame oil. In the present study, an attempt was made to identify the constituen...

Two novel hollow-fibre liquid–liquid membrane contactor (HF-LLMC) modules, containing S-type (skin layer with low porosity) and Q-type higher fibres, have been evaluated. Both asymmetric, porous, hydrophobic membranes, made from poly(4-methyl-1-pentene) (PMP), were used as efficient technology for ammonia recovery to produce liquid fertilisers. The ammonia-rich stream was fed into the shell sid...

A study was carried out to examine the effects of different potassium fertilizer sources on growth, fodder yield and quality at Research Farm, Rani Lakshmi Bai Central Agricultural University, Jhansi, Uttar Pradesh. The experiment conducted under semi-arid climatic conditions in a simple Randomized Block Design (RBD) with ten treatments (control, 100% NP, recommended dose (RDK) through MOP, RDK...
