Some transition metal chelates of two ligands L1 and L2 were prepared and characterized by elemental analysis. The IR and 1h NMR spectra of several chelates of two ligands L1 and L2 showed the involvement of the azo group in chelation with the transition metaI ions, in most of the studied chelates, and that the two ligands L1 and L2 showed the involvement of the azo group in chelation with the transition metal ions, in most of the studied chelates, and that the two ligands L1 and L2 were coordinated either in the enol or the keto form. IR spetra also showed that Fe(III)-, Ni(II)-, Mn(II)-, vo(II)-L1 and Cu(II)-L2 chelates behaved in a bidentate manner, in contrast with the two (1:1) M:L cobalt chelates with the two ligands are *** analysis indicated the presence of three to twelve water molecules of hydration eliminated on heating up to 150℃ and one or two coordinated water molecules removed at 150~180℃.The octahedral structure is proposed fOr all the chelates, except Cu(II)-L2 and Ni(II)-L1 chelates which have square planar geometry, based on their electronic spectra

Background:high-intensity interval training(hIIT)induces similar or even superior adaptations compared to continuous endurance ***,just 6 hIIT sessions over 2 weeks significantly improves maximal oxygen uptake(vo_(2max)),submaximal exercise fat oxidation,and endurance *** even faster adaptations can be achieved with hIIT is not ***,we aimed to determine whether 2 sessions of hIIT per day,separated by 3 h,every other day for 5 days(double hIIT(hIIT-D),n=15)could increase vo_(2max),submaximal exercise fat oxidation,and endurance capacity as effectively as 6 sessions of hIIT over 2 weeks(single hIIT(hIIT-S),n=13).Methods:Each training session consisted of 10×60 s of cycling at 100%of vo_(2max)interspersed with 75 s of low-intensity cycling at 60 watt(W).Pre-and post-training assessments included vo_(2max),time to exhaustion at-80%of vo_(2max),and 60-min cycling trials at-67%of vo_(2max).Results:Similar increases(pvo_(2max)(hIIT-D:7.7%***-S:6.0%,p>0.05)and endurance capacity(hIIT-D:80.1%***-S:79.2%,p>0.05)were *** exercise carbohydrate oxidation was reduced in the 2 groups after exercise training(hIIT-D:9.2%,p=0.014 ***-S:18.8%,p=0.012)while submaximal exercise fat oxidation was significantly increased in hIIT-D(15.5%,p=0.048)but not in hIIT-S(9.3%,p=0.290).Conclusion:Six hIIT sessions over 5 days was as effective in increasing vo_(2max)and endurance capacity and was more effective in improving submaximal exercise fat oxidation than 6 hIIT sessions over 2 weeks.

Biomass seaweed Cladophora sp. (BSC) included Cladphora socialis, Cladophora prolifera, Cladophora crupila, which was hydrolysised in dilute sulfuric acid and enzymatic hydrolysis of cellulase. BSC was treated by dilute sulfuric acid at concentration of 0, 0.5%, 1%, 2%, 3%, 4%, 5%, 6% (v/v) (v volume) in autoclave respectively at 121 °C at time 20, 40 and 60 minute, with the rate between seaweed and solution acid of 1/10(w/v) (w weight). Beside, BSC was pretreated in dilute sulfuric acid at 0.5%(v/v) at 121 °C in 20 minute, after it was treat at concentrations 0, 0.2, 0.4, 0.6, 0.8, 1 ml/g with the enzymatic hydrolysis consisted of cellulase in control (50 °C, ph 5.0, 24 h). The results showed that, total sugar contents of two methods are the same, but sugar content was varied by treatment time of heat. Rates of acid 4%; 5%, 6% (v/v) and 0.8; 1 ml/g have high sugar content within the range of 42.38-48.51 mg/ml. 400 ml of hydrolysis solution was fermented by Saccharomyces cerevisiae at 30 °C for 72 h. After fermentation, 5% ethanol solution was identified for the first 100 ml evaporate solution. BSC is easily hydrolyzed and fermented to ethanol, this shows excellent prospects as a potential feedstock for the production of bioethanol.

high-spin states in 145Tb have been populated using the 118Sn (32S, 1p4n) reaction at beam energy of 165 MeV. The level scheme of 145Tb has been established up to Ex ≈7.4 MeV. The level scheme shows characteristics of a spherical or slightly oblate nucleus. Based on the systematic trends of the level structure in the neighboring N = 80 isotones, the level structure in 145Tb below 2 MeV excitation is well explained by coupling an h11/2valence proton to the even-even 144Gd core. Above 2 MeV excitation, most of the yrast levels are interpreted with multi-quasiparticle shell-model configurations.
