In this work, a novel dual-nozzle ejector enhanced triple-evaporator refrigeration cycle (DETRC) without separator is proposed to improve the performance of the conventional ejector one (CETRC). The performance of DETRC is analyzed and compared with CETRC in term of energy coefficient of performance (COPen). Under given operating conditions, the COPen improvement of the no...

BACKGROUND Failed visualization of the fetal nasal bone (NB) by ultrasound at 11 - 14 weeks of gestation is strongly associated with chromosomal abnormalities. Meanwhile, the incidence of the absent fetal NB in normal fetuses in the first trimester in mothers of different ethnic origins differs significantly. It is, therefore, important to assess ethnic variations in the first-trimester visuali...

The phosphoenolpyruvate:glycose phosphotransferase system (PTS) participates in important functions in the bacterial cell, including the phosphorylation/uptake of PTS sugars. Enzyme I (EI), the first protein of the PTS complex, accepts the phosphoryl group from phosphoenolpyruvate, which is then transferred through a chain of proteins to the sugar. In these studies, a mutant GFP, enhanced yello...

This retrospective, descriptive study aimed to assess hematologic testing practices in 100 patients with preeclampsia undergoing neuraxial blockade (NB). Prior to NB, platelet (PLT) count was performed in 61 (98%) of 62 women in labor and in 37 (97%) of 38 women undergoing cesarean delivery (CD). No patients had a pre-NB PLT count <70 × 10(9)/L. Pre-NB tests for prothrombin time (PT) and activa...

Introduction: Iron deficiency anemia and beta-thalassemia trait are the two most common causes of hypochromic microcytic anemia. There are some discriminating functions (DFs) formula to differentiate these two conditions based on RBC's indices which would be compared the validity of the 14 various indices in this study. Correspond...

In the title compound, [Nb(CH(3)O)(2)(C(5)H(7)O(2))Cl(2)], a slightly distorted octa-hedral coordination geometry is observed around the Nb(V) atom with Nb-O distances in the range of 1.8254 (16)-2.0892 (16) Å and Nb-Cl distances of 2.3997 (14) and 2.4023 (12) Å. The O-Nb-O angles vary between 81.36 (7) and 172.65 (7) °, while the trans Cl-Nb-Cl angle is 167.34 (2)°. There are no hydrogen bonds...

BACKGROUND Energy intake (EI) during weight loss is difficult and costly to measure accurately. OBJECTIVE The objective was to develop and validate a computational energy balance differential equation model to determine individual EI during weight loss. DESIGN An algorithm was developed to quantify EI during weight loss based on a validated one-dimensional model for weight change. By using ...

Since the acute toxicity of nitrobenzene (NB) in rats has not been characterized, experiments were performed to ascertain the possible deleterious effects of NB in different tissues of the male Fischer-344 rat. Rats were given single oral doses of NB (50-450 mg/kg) and at the time of sacrifice, 25 tissues were removed and examined histologically by light microscopy. Histopathological changes in...

Emotional intelligence (EI) has attracted considerable interest amongst both individual differences researchers and those in other areas of psychology who are interested in how EI relates to criteria such as well-being and career success. Both trait (self-report) and ability EI measures have been developed; the focus of this paper is on ability EI. The associations of two new ability EI tests w...
