Electrochemical treatment of Poultry Slaughterhouse Wastewater using Iron and Aluminium Electrodes

Electrochemical process for the treatment of poultry slaughterhouse wastewater (PSWW) was studied. The effects of some key factors such as initial pH, current density, operating time and the kind of electrodes on the removal of chemical oxygen demand (COD), oil and grease, total suspended solids (TSS), total kjeldahl nitrogen (TKN) and total phosphors (TP) were investigated. It is clear that the process has a good efficiency. The highest removal amount of COD (95.6) was achieved with aluminium electrode (pH value between 2 and 3 and charge passed 20.34x10(3) colons (current density 0.014 A cm(-2)). 95.3 of oil and grease was removed in the same conditions, of course, in the case of iron electrode. The maximum removal efficiency for TKN and TP were 77.8 and 89.6 respectively (pH 3, charge passed 30.51x10(3) colons and with aluminium). Consequently electrocoagulation is comparatively suitable process for PSWW treatment

Quadratic alpha' corrections to T-duality

The quadratic alpha' corrections to the two-dimensional black hole and to its T-dual are calculated. These backgrounds are used to write the covariant form of the quadratic alpha' corrections to the T-duality for general time-dependent backgrounds of dilaton and diagonal metric in the bosonic string theory.Comment: 15 pages, JHEP; typos corrected, references adde

Pengaruh Latihan Kegel Terhadap Frekuensi Inkontinensia Urine Pada Lansia Di Unit Rehabilitasi Sosial Margo Mukti Rembang

The purpose of this study was to determine the influence of the Kegel exercise on frequency of urinary incontinence in the elderly. This study used a quasi -experimental with one group pre and post test study design, conducted on 27 respondents selected by purposive sampling technique. Respondents were divided into three groups which were the first group with frequency of exercise 2 times, the second group with 3 times and the third group 4 times a day for six weeks. Data on the frequency of urinary incontinence were collected in pre and post intervention Kegel exercise. Data were analyzed using t-test (paired t-test).The results of the study revealed that group I , II & III in sequence value of t-count 21.92, t=11,418 and t=15.307 with P values p=0, 00. Further comparisons between the three groups showed group III showed the mean frequency of urinary incontinence at least. It can be concluded that Kegel exercises affect the decrease in the frequency of urinary incontinence in the elderly, and it is suggested that Kegel exercises should be done regularly

Grand multiparity associations with low bone mineral density and degraded trabecular bone pattern

Introduction: Pregnancy is associated with changes in bone remodeling and calcium metabolism, which may increase the risk of fragility fracture after menopause. We hypothesized that in postmenopausal women, with history of grand multiparity, the magnitude of trabecular bone deterioration is associated with number of deliveries. Methods: 1217 women aged 69.2 ± 6.4 years, from the Bushehr Elderly Health (BEH) program were recruited. The areal bone mineral density (aBMD) of the lumbar spine and femoral neck and trabecular bone score (TBS) of 916 postmenopausal women, with grand multiparity defined as more than 4 deliveries, were compared with those of 301 postmenopausal women with 4 or fewer deliveries. The association of multiparity with aBMDs and TBS were evaluated after adjustment for possible confounders including age, years since menopause, body mass index, and other relevant parameters. Results: The aBMD of femoral neck (0.583 ± 0.110 vs. 0.603 ± 0.113 g/cm2), lumbar spine (0.805 ± 0.144 vs. 0.829 ± 0.140 g/cm2) and TBS (1.234 ± 0.086 vs. 1.260 ± 0.089) were significantly lower in women with history of grand multiparity than others. In the multiple regression analysis, after adjusting for confounders, the negative association did persist for lumbar spine aBMD (beta = −0.02, p value = 0.01), and the TBS (beta = −0.01, p value = 0.03), not for femoral neck aBMD. Conclusion: We infer that grand multiparity have deleterious effects on the aBMD and the trabecular pattern of the lumbar spine

Associations between the lipid profile and the lumbar spine bone mineral density and trabecular bone score in elderly Iranian individuals participating in the Bushehr Elderly Health Program: a population-based study

Summary: We hypothesized that the lipid profile or dyslipidemia may have an influence on the bone mineral density and bone microstructure in an elderly Iranian population. The results of this study showed some significant associations between the serum lipid levels and the lumbar spine and femoral areal bone mineral densities and the trabecular bone score (TBS). Purpose: Serum lipid abnormalities are possible risk factors for cardiovascular diseases and osteoporosis. Our aim was to evaluate the associations between the lipid profile and the areal bone mineral density (aBMD) and trabecular bone score in an elderly Iranian population. Methods: The study subjects included 2426 elderly women and men participating in the second stage of the Bushehr Elderly Health program, a population-based prospective cohort study. The aBMDs of the lumbar spine and femoral neck and the lumbar spine texture were measured using dual-energy X-ray absorptiometry and the TBS algorithm, respectively. The associations between the lipid profiles and the aBMDs and TBSs were examined using multivariable linear regression analyses stratified by sex and adjusted for potential confounders. Results: In men, we found negative correlations between the lumbar spine aBMD and TBS and the total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), and low-density lipoprotein cholesterol (LDL-C) levels (TC: p < 0.001 and p < 0.006, HDL-C: p = 0.002 and p = 0.004, and LDL-C: p < 0.001 and p < 0.009, respectively). However, only the HDL-C level was negatively associated with the aBMD in women (p = 0.016). A positive and statistically significant correlation was found between the serum triglyceride (TG) level and the aBMD in the women (p < 0.001). The TG level and the TBS were not statistically significantly correlated in either sex, and the TBS was not correlated with any of the lipid values in women. Conclusion: The results of this study showed some significant but generally weak associations between the lipid profile and the aBMD. The associations that were significant for both the men and the women included positive associations between the TG level and the femoral neck aBMD, as well as the HDL-C level and the femoral neck and lumbar spine aBMD

Screening ethnically diverse human embryonic stem cells identifies a chromosome 20 minimal amplicon conferring growth advantage

The International Stem Cell Initiative analyzed 125 human embryonic stem (ES) cell lines and 11 induced pluripotent stem (iPS) cell lines, from 38 laboratories worldwide, for genetic changes occurring during culture. Most lines were analyzed at an early and late passage. Single-nucleotide polymorphism (SNP) analysis revealed that they included representatives of most major ethnic groups. Most lines remained karyotypically normal, but there was a progressive tendency to acquire changes on prolonged culture, commonly affecting chromosomes 1, 12, 17 and 20. DNA methylation patterns changed haphazardly with no link to time in culture. Structural variants, determined from the SNP arrays, also appeared sporadically. No common variants related to culture were observed on chromosomes 1, 12 and 17, but a minimal amplicon in chromosome 20q11.21, including three genes expressed in human ES cells, ID1, BCL2L1 and HM13, occurred in >20% of the lines. Of these genes, BCL2L1 is a strong candidate for driving culture adaptation of ES cells
