103High volume and low concentration of anaesthetic solution in the perivascular interscalene sheath determines quality of block and incidence of complications

Though analysis and determination on wastewater quality of Gas Field, it can be seen that the main organic matter in wastewater is low concentration methanol. Aiming at the characteristics of higher degree of mineralization, methanol and lower pH ,the experiment is focusing on the effect of manganese dioxide & hydrogen peroxide catalytic oxidation process on methanol wastewater treatment properties and functions.The results show, for low concentration methanol wastewater,the manganese dioxide used has a diameter of 5nm with a dosage of 300mg/L, also a illumination intensity of 120Q, when the dosing ratio with hydrogen peroxide is 1:10, after 8h reaction period, the degradation rate of methanol were all above 70.0%.The methanol content after treated can meet the reference standard for Gas Field reinjection water

AbstractEpitaxial layers (EL) Si:Sn doped with Yb in the process of liquid phase epitaxy were studied by optical microscopy and photoluminescence (PL) methods.At low concentration of lanthanoid (0,01 < Nyb > 0,1 weight %) the good planarity of the interface and high quality of the surface are detected. At NYb > 0,1 weight % microirregularities are presented.In EL Si:(Sn, Yb) irradiated by 4,5 MeV-electrons the suppression of the generation of radiaton defects, responsible for G– and C-lines of PL, has been found. This effect has been explainedwithin the score of the model takeng into the consideration gettering propering ofYb in reference to the impurities of 0 and C as deformation fields, attributed to the presence of Sn atoms.

Increasing Student Learning

The concentration of student learning will influence the process and learning outcomes obtained by students. if students have low concentration, the quality of learning is also low. Students who have low concentration, the quality of learning is also low. Therefore, this study aims to increase the concentration of students in Pancasila and Citizenship Education subjects. This type of research is Class Action Research (CAR). The research subjects were 32 grade VII3 students at SMPN 7 Muara Bungo. This type of research is Class Action Research (CAR). The research subjects were 32 grade VII3 students at SMPN 7 Muara Bungo. Class action research is carried out in two cycles with procedures including 1) Planning, 2) Actions, 3) Reflections and 4) Evaluation. The results of the study indicate that the application of the picture to picture method can increase the concentration of student learning. this is indicated by the increasing completeness of student learning outcomes from the first cycle of only 65.62%, increasing to 87.50% in cycle II. Then the absorption of students in PPKn learning by using the picture to picture method increased from the first cycle of 68.90% to 88.59% in cycle II. As well as increasing student learning activities from the first cycle 68.75% increased to 84.37% in the second cycle with a good category.

Abstract Background: Knee osteoarthritis (KO) is one of the most common joint diseases, often determining knee pain and reduction of mobility with impact on the overall quality of life of the patients. Intra-articular injections of different formulations of platelet rich plasma (PRP) are an increasingly common non-surgical treatment for KO. Recently, in order to combine the antinflammatory effect of platelet rich plasma and the viscosupplementation effect of hyaluronic acid, a formulation of plasma with relatively low concentration of platelets and very few leukocytes combined with hyaluronic acid (PRP+HA) has been proposed. The purpose of this study is to retrospectively compare the effectiveness of plasma with high concentration of platelets and leukocytes (L-PRP) with PRP+HA in patients with mild to moderate (Kellegren-Lawrence scale II-III grade) KO.Materials and Methods: Among the 51 patients included, 28 have been treated with L-PRP, while 23 with PRP+HA. A retrospective evaluation at baseline (T0), after 3 months (T1) and 1 year (T2) has been performed. The outcome analyzed are the Knee Society Score(KSS), the Visuo Analogic Scale (VAS) (at T0,T1 and T2) and the Knee injury and Osteoarthritis Outcome Score(KOOS) (T0 and T2).We evaluated change in mean scores within group among different time points using repeated measures ANOVA or paired t-test. Comparison between different groups of treatment has been performed using mixed ANOVA.Results: The main finding is that, although the two treatments have been both effective, PRP+HA determined significantly better functional status, pain and mobility, measured with KSS.Discussion: We observed a significant effect of the two formulations in exam in all the outcomes in analysis: both treatments were effective in improving pain, knee functional status and symptoms, and the benefits persisted after 3 and 12 months from the infiltrative therapy. Nevertheless, patients who received PRP+HA injections presented higher knee mobility and better function (measured by KSS score) after one year.Conclusions: This work compares clinical outcomes of L-PRP and PRP+HA treatment in patients with KO. Our results encourage the use of one of the two treatments in patients with mild to moderate KO. When possible, we suggest to the use of PRP+HA formulation, because it may determine better results in improving knee function and mobility.

Polyunsaturated fatty acids (PUFAs) supplementation has been widely discussed as a strategy for improving meat quality in pig production, but the effects are inconsistent. This meta-analysis was performed to comprehensively evaluate its effects on the meat quality and growth performance of pigs. We searched the PubMed and the Web of Science databases (articles published from January 1, 2000 to October 16, 2020) and compared PUFAs-supplemented diets with control diets. We identified 1,670 studies, of which 14 (with data for 752 pigs) were included in our meta-analysis. The subgroup analysis was classified as PUFA source [conjugated linoleic acid (CLA) or linseed], concentration (high or low concentration), and initial stage (growing or finishing pigs). Our analysis found that PUFA supplementation increased the intramuscular fat (IMF) content (WMD = 0.467%, 95% CI: 0.312–0.621, p < 0.001), decreased the meat color L* (WMD = −0.636, 95% CI: −1.225 to −0.047, p = 0.034), and pH 24 h (WMD = −0.021, 95% CI: −0.032 to −0.009, p < 0.001) but had no influence on drip loss, meat color a* and b*, pH 45 min, and growth performance. CLA supplementation improved IMF content (WMD = 0.542%, 95% CI: 0.343–0.741, p < 0.001) and reduced meat color b* (WMD = −0.194, 95% CI: −0.344 to −0.044, p = 0.011). Linseed supplementation increased IMF content (WMD = 0.307%, 95% CI: 0.047–0.566, p = 0.021), decreased meat color L* (WMD = −1.740, 95% CI: −3.267 to −0.213, p = 0.026), and pH 24 h (WMD = 0.034, 95% CI: −0.049 to −0.018, p < 0.001). We discovered an increase on the IMF content in both high and low concentration PUFA supplementation (WMD = 0.461%, 95% CI: −0.344 to −0.044, p < 0.001; WMD = 0.456%, 95% CI: 0.276–0.635, p < 0.001). Furthermore, we also found the effects of PUFA supplementation on meat color L* and pH 24 h are concentration- and stage-dependent. PUFA supplementation can improve the meat quality of pigs, which mainly emerges in greatly increasing IMF content.
