Introduction: Hyponatremia is the commonest electrolyte derangement seen in medical and surgical wards and in high dependency treatment units. It is associated with prolonged hospital stay, high economic burden and increased morbidity and mortality. Hyponatremia is well reported in medical and surgical conditions but literature is scanty concerning its relationship with treatment outcome in patients managed in high dependency heart and vascular surgical centers. Objectives: To determine the prevalence, determinants, clinical correlates and outcome of pre-operative hyponatremia. Methods: Retrospective study involving patients that had surgery (cardiac and vascular) between january 2015 and December 2019. Data were obtained from patients’ case files, perioperative and intensive unit charts. All participants with preoperative hyponatremia had their serum sodium corrected to ≥135 mmol before surgical incision and those with hypernatremia had their sodium corrected to cio-demographic, clinical, laboratory findings were entered. Statistical analysis was done using student’s t-test and chi square. Results: Of the 305 participants (186 males and 119 females), pre-operative hyponatremia was found in 30.8% and normonatremia in 59.7%. Pre-operative hyponatremia was more common in advance age, overweight, those presenting for open heart and other major surgeries and those with background chronic heart failure and chronic liver disease. Participants with pre-operative hyponatremia had shortened and also prolonged hospital stay and higher risk of death than with normonatremia. conclusion: Pre-operative hyponatremia is common in high dependency surgical unit particularly in the elderly, those with comorbidities and those presenting for major heart surgeries. It impacts negatively on the morbidity and mortality as it could shorten hospital stay through death, and could prolong hosp

HfSiO(N) films were prepared on Si substrates by using dual ion beam sputtering deposition(DIbSD).Structure and electronic properties of the film with different annealing temperature were investigated.X-ray photoelectron spectroscopy (XPS) spectra showed that silicidation action occurs by annealing at 850 and 900℃for HfSiO and HfSiON film,*** annealing at 900 and 950"c,metallization reaction was rapidly promoted for the HfSiO and HfSiON film,*** incidence X-ray diffraction(GI-XRD) patterns indicated crystallization in the HfSiO and HfSiON film after 850 and 900"c respectively.c-V measurements indicated that the dielectric constants for the HfSiO and HfSiON film were 17.1 and 18.7, *** oxide-charge densities were found to be 5.6x10" for the HfSiO film and 2.2×10 cm for the HfSiON film.Ⅰ-Ⅴcharacteristics showed that the leakage current density(1.3×10 and 5.9×10 A/m at(V-1) V) was obtained after 900 and 950℃annealing for HfSiO and HfSiON film,*** of these indicated that the electrical performance of HfSiO gate dielectrics had a lager improvement through nitrogen incorporation.

使用Gammasphere多探测器系统对252cf裂变源瞬发γ射线进行γ-γ-γ和γ-γ(θ)符合测量,A～100(Z～40,N>56)丰中子核区关于形状过渡、形状共存和形状突变的深入研究获得了新的进展。奇-Z核的系统研究揭示了从Z=39(Y)同位素的轴对称大四极形变到Z=43(Tc),44(Ru)和45(Rh)同位素中具有中等四极形变之大三轴形变的过渡。Nb(Z=41)同位素具有过渡核的特征。根据邻近同位素和同中素带交叉信息的系统性及推转壳模型(cSM)计算,Tc和Rh偶-N同位素中观察到的带交叉产生于一对h11/2中子的转动顺排。首次观察到100Nb(Z=41,N=59)的高自旋能级纲图和形变态,从而证实了100Nb中的形状共存,并确认,在Nb同位素链上,基态形状突变发生于N=58(球形)到N=59(大形变);而在Sr(Z=38),Y(Z=39)和Zr(Z=40)各同位素链上,基态形状突变均发生于N=59(球形)到N=60(大形变)。100Nb具有大形变基态,同现有理论预言相矛盾,其大形变的基态及转动带所具有的很大的和不规则的转动惯量具有重要的理论意义。对奇-质子cs(Z=55)和La(Z=57)丰中子同位素八极激发的详细研究,发现了141,143,144cs同位素链上电二极矩D0随中子数增加而减小的急剧变化,此前在145,147La中观察到的电二极矩D0的较缓和的减小似乎亦很陡地下延至148La。在cs和La同位素中观察到的电二极矩D0的急剧下降很可能同偶-质子核146ba和224Ra中观察到的电二极矩D0的急剧下降相类似,后者已获反射非对称平均场壳修正理论的成功解释。实验证明,141cs具有很大电二极矩D0。141cs和142Xe中观测到的很大的电二极矩D0和仅在141cs中观察到的电二极矩D0的simplex量子数相关性需要进一步的理论研究。根据转动频率比值ω-(I)/ω+(I)的检定,同Xe同位素一样,认定cs同位素中包括号143cs的八极激发为八极振动,而在La同位素中存在八极形变。

The quantitative and qualitative composition of chinese municipal solid waste (MSW) differs significantly from German waste. The focus of this paper is on whether these differences also lead to dissimilar qualities of leachates during storage or landfilling. Leachates ingredients determine the appropriate treatment technique. MSW compositions of the two cities Guilin (china) and Essen (Germany), each with approx. 600 000 inhabitants, are used to simulate chinese and German MSW types. A sequencing batch reactor (SbR) is used, combining aerobic and anaerobic reaction principles, to test the biodegradability of leachates. Leachates are tested for temperature, pH-value, redox potentials, and oxygen concentration. chemical oxygen demand (cOD) values are determined. Within 8 h, the biodegradation rates for both kinds of leachates are more than 90%. Due to the high organic content of chinese waste, the degradation rate for Guilin MSW leachate is even higher, up to 97%. The effluent from SbR technique is suitable for direct discharge into bodies of water.
