The minimum fluidization velocity(U_(mf))is a key parameter for the scale-up of inverse liquid-solid flu-idized *** predictions using common correlations were compared against experimental minimum fluidization velocity measurements of low density(28-638 kg/m^(3)),0.80-1.13 mm Styrofoam particles in a fluidized bed with a height of 4.5 m and 0.2 m *** average absolute relative deviation for the predicted minimum fluidization velocity for particles below 300 kg/m^(3) was above 40%using the studied common correlations.A modified Wen and Yu correlation was thus proposed based on novel and past measurements with low-density and small-diameter particles,expanding the range for predicting U_(mf).The new correlation predicted U_(mf) with deviations below 15%for ST028,ST122 and *** modified correlation also improved U_(mf) predictions for comparable particles from a previous study,demonstrating its validity for a larger range of low-density particles.

Ricinus communis L.(R. communis), commonly known as castor oil plant, is used as a traditional natural remedy or folkloric herb for the control and treatment of a wide range of diseases around the globe. Various studies have revealed the presence of diverse phytochemicals such as ***, terpenes, saponins,phenolic compounds such as kaempferol, gallic acid, ricin, rutin, lupeol, ricinoleic acid, pinene, thujone and gentisic *** phytochemicals have been responsible for pharmacological and therapeutic effects,including anticancer, antimicrobial, insecticidal, antioxidant, anti-diabetic, antinociceptive,anti-inflammatory. bone regenerative, analgesic, and anticonvulsant activity. R. communis harbours phytochemicals which have been shown to target peroxisome proliferator activated receptor(PPAR), nuclear factor NF-κ-B, cytochrome p450, P38 mitogen-activated protein kinases kinase(p38 mAPK), tumor protein P53, B-cell lymphoma-extra-large(Bcl-xL) and vascular endothelial growth factor receptor-2(VEGFR-2). Considering its wide variety of phytochemicals, its pharmacological activity and the subsequent clinical trials, R. communis could be a good candidate for discovering novel complementary drugs. Further experimental and advanced clinical studies are required to explore the pharmaceutical, beneficial therapeutic and safety prospects of R. communis with its phytochemicals as a herbal and complementary medicine for combating various diseases and disorders.

Nano-ZnO particle was produced by evaporating zinc powders in air at air flow-rate from 0.2 to 0.6m3/h. Nano-ZnO particles was formed by the oxidation of the evaporated zinc vapor. X-ray diffraction shows the powders to be ZnO with lattice parameters of a=0.3249nm and c=0.5205nm. The particle size is dependent upon the transit time from the source to the collection area. The size of particles was ranged between 81 to 103nm. The average density resulted was 4.865g/cm3. Normal ZnO and nano-ZnO were investigated to use them in aluminum metallurgy as an inert anode material. A certain amount of both oxides were molded subsequently inserted to the molten cryolite-aluminum oxide to investigate the corrosive behavior of both oxides. When the sintering temperature increased up to 1300℃, the weight loss ratio rose to 5.01%-7.33% and up to 7.67%-10.18% for nano-ZnO and normal ZnO, respectively. However, when the samples in the molten cryolite aluminum oxide were put for long time, the corrosive rate was found to be higher. It was found that the corrosive loss weight ratio of nano-ZnO anode was much lower than the normal one made from ordinary-ZnO providing that the nano-ZnO is more possible to be use inert anode material.

BACKGROUND Calciphylaxis is a form of vascular calcification more commonly associated with renal disease. While the exact mechanism of calciphylaxis is poorly understood,most cases are due to end stage kidney disease. However, it can also be found in patients without kidney disease and in such cases is termed non-uremic calciphylaxis for which have multiple proposed *** SUmmARY We describe a case of a thirty-year-old morbidly obese Caucasian female who had a positive history of alcoholic hepatitis and presented with painful calciphylaxis wounds of the abdomen, hips, and thighs. The hypercoagulability panel showed low levels of Protein C and normal Protein S, low Antithrombin Ⅲ and positive lupus anticoagulant and negative anticardiolipin. Wound biopsy confirmed the diagnosis of non-uremic calciphylaxis in the setting of alcoholic liver disease. The calciphylaxis wounds did not improve when Sodium Thiosulfate was used alone. The patient underwent a series of bedside and surgical debridement. Broad spectrum antibiotics were also used for secondary wound bacterial infections. The patient passed away shortly after due to sepsis and multiorgan *** Non-uremic Calciphylaxis can occur in the setting of alcoholic liver disease. The treatment of choice is still unknown.

We investigate quasi-local energy distribution and thermodynamics of the Reissner-Nordstr6m black hole space-time surrounded by quintessence. We use the quasi-local energy distribution from Einstein energy-momentum complex. We plot the variation of the energies, temperature and heat capacity with the state parameter related to the quintessence ωq. We show that due to the presence of quintessence, the total energy of the outer region as well as the temperature and heat capacity decreases with the increase of the density of quintessence, while the total energy of the black hole region increases.

In the previous paper, in order to express steadystate ratchetting, the present s extended the cyclic plasticity model proposed by Ohno and Wang (1993), and the validity of the extended model was discussed on the basis of uniaxial ratchetting experiments of 316FR steel at room temperature. In the present paper, the validity of the extended model is discussed further on the basis of nonproportional experiments of IN738LC at 850 such as multiaxial ratchetting, multiaxial cyclic stress relaxation, circular cyclic straining with strain hold, and so on. Predictions based on the OhnoWang model as well as the ArmstrongFrederick model are also given for the sake of comparison. It is shown that the extended model is capable of simulating the nonproportional experiments accurately, and especially that the extended model can predict much less steadystate ratchetting than the ArmstrongFrederick model. It is also shown that the extended model provides almost the same predictions as the OhnoWang and th

The insulin-like growth factor 1（IGF1） gene is a member of the group of somatotropin axis genes that play a significant role in cell proliferation and growth of muscles. Here, we searched for polymorphisms in buffalo IGF1 and found two novel single nucleotide polymorphisms（SNPs）, G64 A and G280A, in the noncoding sequences of exon 1 and exon 4, respectively. Statistical analysis of different genotypes showed that the individuals with GG genotypes had significantly（P〈0.05） higher body weight（BW） and average daily gain（ADG） than those with other genotypes at ages of 3–6 months in G64A SNP and 6–9 months in G280A SNP. The combined genotypes of these two SNPs produced three haplotypes, GG/GG, AG/AG, and AA/AA, which were significantly associated（P〈0.0001） with BW and ADG at an age from 3 to 12 months. Buffaloes with the homozygous GG/GG haplotype showed higher growth performance than other buffaloes. The two SNPs were correlated with m RNA levels of IGF1 and IGF1 receptor（IGF1 R） in semitendinosus muscle as well as with the serum concentration level of IGF1. Also, buffaloes with GG/GG haplotype showed higher m RNA and serum concentration levels. The data revealed that these two SNPs could be valuable genetic markers for selection of Egyptian buffaloes for better performance in the population.
