Pressure-density-temperature (PρT) properties, vapor pressures, and saturated liquid and vapor densities for refrigerants R 1234ze(Z) (cis-1,3,3,3-tetrafluoroprop-1-ene; CF3CHCHF) and R 245fa (1,1,1,3,3-pentafluoropropane; C3H3F5) were measured with two types of isochoric methods. Pressure was ...

The uniqueness of positive Z-eigenvector of nonnegative tensors has many important applications in both theory and practical application. In this paper, we give a sufficient condition that a nonnegative tensor has unique positive Z-eigenvector by using its entries. For the third order transition...

To Prof. Jürgen Köhler to his 60th birthday.ORCs (Organic Rankine Cycle) experience growing interest for the generation of electricity from industrial waste heat. However, the widely used working fluid R-245fa does not seem to be sustainable due to its relative high GWP (Global Warming Potentia...

Decisions are made based on information. Information must be reliable in order to be useful and in many subjects this confidence depends on some conditions. Thus, the Z-Advanced number (ZA-number) consists of several parts each of which play their own roles. The ZA-number is classified in two ma...

We report a systematic study of Z+jet correlation in Pb+Pb collisions at the LHC by combining the next-leading-order matrix elements calculations with matched parton shower in Sherpa for the initial Z+jet production, and Linear Boltzmann transport Model for jet propagation in the expanding quark...

A Hydro-Fluoro-Olefin refrigerant cis-1,1,1,4,4,4-hexafluoro-2-butene (R-1336mzz(Z)) has low global warming potentials and it is considered as a potential working fluid for high temperature heat pump and Organic Rankine Cycle. Thermophysical properties of this fluid are necessary to be used in p...

Z-pins offer effective through-thickness reinforcement for laminated composites. Various studies have however, shown that metal Z-pins are less effective at bridging Mode I delaminations than carbon-fibre composite Z-pins, due to poor interfacial bonding with the laminate. This is exacerbated by...

Opposite signs of specific rotation are reported in the literature for (4S,5S)-(2,2-dimethyl-5-phenyl-[1,3]dioxolan-4-yl)-methanol. The correct assignment was made by unambiguous synthesis of the title compound via the reaction of (S)-O-TBS-mandelic aldehyde with vinyl magnesium chloride, separa...

In recent years, the frequent eutrophication of water bodies around the world has led to the accumulation of microcystins (MC-LR) in water bodies, causing great harm to humans and aquatic organisms. In this study, a Z-scheme Ag3PO4/NG/PI composite photocatalyst was fabricated by using silver ort...

In collision-induced dissociation (CID) experiments of peptides, the formation of c- and z-ions originating from NCα bond cleavage of the peptide backbone is unusual, whereas b- and y-ions are often observed in positive-ion CID spectra. Here we report that characteristic product c- and z-ions c...

The new arginine derivatives Fmoc-Argω,ω′(Boc)2 -OH and Z-Argω,ω′ (Boc)2 -OH have been easily prepared in hiqh yield starting from Z-Orn-OH and N,N′-bis (tert-butoxycarbonyl) -S-methylisothiourea.

CQ 32-084 and CQP 201-403, two ergot derivatives that previous behavioural studies in rats had suggested to be differently active on dopamine (DA) receptors, were IP injected into male chickens. Both compounds strongly modified the animals' behaviour. CQ 32-084 led to sedation, increased ya...

Acute injection of the cannabinoid agonist HU 210 (6.25–100 μgkg, i.p.) dose-dependently inhibited rat locomotor activity and rearing, while subchronic treatment with the drug (once daily for 7 days) at the same doses only diminished locomotion. Acute but not subchronic administration of HU 21...

A 2D finite difference time domain method is used to design a single-mode photonic crystal fiber (PCF) with engineered parameters that is studied with the aim of simultaneous achievement of low loss (below 10−14dB/km) and low chromatic dispersion over a broad band for future optical communicatio...

3-Car☐ypyridinium dichromate (NDC),readly prepared from nicotinic acid and chromium trioxide, is an efficient reagent for the oxidation of alcohols into carbonyl compounds in the presence of pyridine. The optimum molar ratio substrate:reagent:pyridine to ensure complete oxidation of starting mat...

The strengths of a number of monoazo dyes, each containing a (3-carboxypyridinium) triazinyl reactive group, were assessed by titrimetric reduction of the azo groups with a standard solution of titanium (III) chloride. The results obtained by this method initially appeared at variance with those...

Cisplatin, a chemotherapeutic agent for treating various solid tumors, produces hearing loss in approximately half a million cancer patients annually in the United States. In the course of developing a new protective agent against cisplatin-induced ototoxicity, we have been interested in a novel...

The total syntheses of both natural (+)-spiculoic acid A and (+)-zyggomphic acid, new cytotoxic marine natural products of polyketide origin, have been accomplished for the first time. These syntheses were achieved by the highly stereoselective and high-yielding intramolecular Diels–Alder react...

A simple, efficient, green and solvent-free procedure for the synthesis of pyrano[3,2-c]chromen-5-ones has been developed by multi-component condensation of 4-hydroxycoumarin, aldehydes and (E)-N-methyl-1-(methylthio)-2-nitroethenamine in the presence of a catalytic amount of silica-supported tu...

A library of over 20, mainly aryl or heteroaryl, N-methyliminodiacetic acid (MIDA) boronates have been synthesised. A rapid microwave-mediated (MW) method (5–10 min) has been developed using polyethylene glycol 300 (PEG 300) as solvent. However, acetonitrile (MeCN) and dimethylformamide (DMF) w...
