In the present work, for the first time on the basis ofpoly （vinyl alcohol）（PVA）, 2- （4-dimethylaminostyryl）-l-ethylquinolinium iodide （quinaldine red （QR）） and trisodium （4E）-5-oxo- 1-（4-sulfonatophenyl）-4-[（4-sulfonatophenyl）hydrazono]-3 pyrazolecarboxylate （tartrazine （T））, thermostable polarizing film in a wide range of spectra （λmax=394-511 nm） with polarization efficiency （PE） = 98% in absorption maximum and stretching degree （Rs） = 3.5 was developed. The basic spectral-polarization parameters （polarization efficiency and transmittance） of oriented colored PVA-films were measured and discussed. During the work it was found that oriented PVA-films are the phenomenon of anisotropy of thermal conductivity （λ｜/λ⊥）. It is a very important parameter for the development of thermostable PVA-polarizing films. For the first time quantum-chemical calculations using density functional theory （DFT） approach for structural analysis and electronic spectrum of the QR were carried out via the B3LYP/dgdzvp and TDB3LYP/dgdzvp methods. Interpretation of absorption strips in visible region of spectrum was also reported. The excitation energies, electronic transitions and oscillator strengths for the studied structures have also been calculated （B3LYP/dgdzvp）. The NBO analysis and Mulliken atomic charges of the QR were carried out.

Objective: To evaluate the epidemiology of candidiasis and the antifungal susceptibility profile of Candida species isolated from the intensive care unit(ICU) ***: The study used a qualitative descriptive design. Relevant samples depending on organ system involvement from 100 ICU patients were collected and *** and speciation of the isolates was conducted by the biochemical *** susceptibility testing was carried out as per CLSI-M27-A3 ***: Ninety Candida isolates were isolated from the different clinical samples: urine(43.3%), tracheal aspirate(31.1%), urinary catheter(12.2%), endotracheal tube(7.8%),abdominal drains(3.3%), sputum(2.2%). The incidence of candidiasis caused by nonalbicans Candida(NAC) species(63.3%) was higher than Candida albicans(36.7%).The various NAC species were isolated as: Candida tropicalis(41.1%), Candida glabrata(10%), Candida parapsilosis(6.7%), Candida krusei(3.3%) and Candida kefyr(2.2%). The overall isolation rate of Candida species from samples was 53.3%. Antifungal susceptibility indicated that 37.8% and 7.8% of the Candida isolates were resistant to fluconazole and amphotericin B, ***: Predominance of NAC species in ICU patients along with the increasing resistance being recorded to fluconazole which has a major bearing on the morbidity and management of these patients and needs to be further worked upon.

A comparative subgrade moduli study is carried out by static and dynamic deflection methods using lightweight deflectometer and conventional Benkelman beam deflec- tometer on low volume road. Field and laboratory tests are performed at 40 test locations on in-service road of 2 km stretch that contains three common types of cohesive soils （CH, CI, and CL）. Pavement static and dynamic responses are estimated to ascertain static, backcalculated, and composite moduli of subgrade. The backcalculated and composite moduli of subgrade is validated at given moisture content using repeated triaxial test. Static moduli values are on lower side as compared with dynamic moduli values whereas the composite, and laboratory moduli of subgrade are approximately consistent with 2% to 7% variation, respectively. Correlation analyses between static and dynamic moduli of different types of subgrade soils depict good correlation of determination （R2） varies between 0.75 and 0.91. Subsequently, validation of static moduli with California bearing ratio （CBR） related subgrade moduli shows moderate correlation of 0.67 to 0.74 whereas dynamic moduli shows good correlation of 0.74 to 0.93 for different types of soils, respectively. Therefore, the comparative analysis shows that lightweight deflectometer provides reliable subgrade moduli values, and it can be used as a quick subgrade strength evaluating tool for low volume roads.

Background: Blumgart's pancreaticojejunostomy(PJ) has been described with low pancreatic leak rates. This study aimed to evaluate our experience with this technique regarding the pancreatic leak and other perioperative outcomes. Methods: We performed a single-center retrospective analysis of a cohort of 81 patients who underwent pancreaticoduodenectomy in our department from January 2011 to February 2018. The primary endpoint was the occurrence of a clinically relevant postoperative pancreatic fistula(CR-POPF) and analysis of its risk factors. Results: The CR-POPF rate was 12.3%. Fistula risk score(FRS) was the only significant risk factor for the occurrence of overall POPF in multivariate analysis. However, none of the other factors including FRS was found to be significantly associated with CR-POPF risk. A strong positive correlation was found between the CR-POPF and the incidence of delayed gastric emptying, post-pancreatectomy hemorrhage and increased length of hospital stay. Conclusion: Blumgart's technique is a safe technique of pancreatico-enteric anastomosis with low rates of CR-POPF. CR-POPF with this technique is independent of most of the preoperative and intraoperative factors. Therefore, this technique can be used for all types of the pancreas with consistently good results.
