The physicochemical and functional propertiesof seinat seed flour (SSF), defatted seinat flour (DSSF),and protein isolates were studied. Protein was extractedfrom DSSF using an alkali solution with isoelectricprecipitation and freeze drying. Freeze dried seinat seedprotein isolates (FSSPI), SSF, and DSSF were evaluatedfor their physicochemical and functional properties. SSFcontained high levels of crude fat and fiber (31.13% and24.75%, respectively). FSSPI contained 91.83% proteinversus 28.58% for SSF. The amounts of potassium, themineral with the highest content, were 9,548.33, 6,439.03,and 1,029 mg/100 g in SSF, DSSF, and FSSPI, respectively. The functional properties were variable among samples. The protein solubility of FSSPI was significantly higher(p<0.05) than for DSSF and SSF. FSSPI has a significantlybetter (p<0.05) foaming capacity, water/fat absorptioncapacity, and bulk density than SSF and DSSF. FSSPI alsoshowed an emulsifying capacity comparable to commercialsoy protein isolates.
Monitoring bridge scour using dissolved oxygen probes
Azhari, Faezeh,Scheel, Peter J.,Loh, Kenneth J. Techno-Press 2015 Structural monitoring and maintenance Vol.2 No.2
Bridge scour is the predominant cause of overwater bridge failures in North America and around the world. Several sensing systems have been developed over the years to detect the extent of scour so that preventative actions can be performed in a timely manner. These sensing systems have drawbacks, such as signal inaccuracy and discontinuity, installation difficulty, and high cost. Therefore, attempts to develop more efficient monitoring schemes continue. In this study, the viability of using optical dissolved oxygen (DO) probes for monitoring scour depths was explored. DO levels are very low in streambed sediments, as compared to the standard level of oxygen in flowing water. Therefore, scour depths can be determined by installing sensors to monitor DO levels at various depths along the buried length of a bridge pier or abutment. The measured DO is negligible when a sensor is buried but would increase significantly once scour occurs and exposes the sensor to flowing water. A set of experiments was conducted in which four dissolved oxygen probes were embedded at different soil depths in the vicinity of a mock bridge pier inside a laboratory flume simulating scour conditions. The results confirmed that DO levels jumped drastically when sensors became exposed during scour hole evolution, thereby providing discrete measurements of the maximum scour depth. Moreover, the DO probes could detect any subsequent refilling of the scour hole through the deposition of sediments. The effect of soil permeability on the sensing response time was also investigated.

Background: Breast cancer is the commonest cancer in Egyptian females. Nrf2 is involved in oxidative stress while P73 functions in response to DNA damage. This study aimed to assess the role of Nrf2 promoter and P73 G4C14 to A4T14 SNPs in breast cancer in Egypt. Patients: Eighty-five female patients with breast tumours (41 malignant, 44 benign) were included. Nrf2 (rs6721961) and p73 (G4A) SNPs were determined by PCR- CTPP assay. Results: Genotype frequencies of the Nrf2 promoter SNP were 34.2% and 37.9% for AA in benign and malignant groups respectively, and 43.9% and 40.5% for CC and, 21.9 % and 21.6% for CA. Genotype frequencies for the P73 G4A SNP were 52.9% and 44.7% for GA in benign and malignant groups respectively, and 47.1% and 55.3% for GG. Discussion: Nrf2 genotypes in pre - and post-menopausal patients, showed significantly different distributions in the 2 patient groups, the AA genotype being significantly more common in pre-menopausal patients. The P73 G4A SNP showed no relation to age of disease onset. Conclusion: The Nrf2 (rs6721961) AA genotype might be related to early breast cancer onset. In contrast the P73 G4A polymorphism showed no relation to either disease risk or age at presentation.

This study predicts concentration and dispersion pattern of primary pollutants in Kuala Lumpur city centre. The forecast was carried out under different traffic scenarios; business as usual (BAU) and 30% traffic reduction to see the impact of traffic reduction for a sustainable city management. The Danish OML-Highway model was utilized to calculate hourly time series of particulate matter concentration and distribution caused by traffic emission under different scenario. The average concentration of PM2.5 are 37.6±24.3 μg/m³ and 35.3±23.9 μg/m³ for BAU and 30% traffic reduction scenario respectively, while average concentration of PM10 are 54.5±27.8 μg/m³ and 50.8±26.4 μg/m³ for BAU and 30% traffic reduction scenario respectively. The spatial concentration distribution of annual mean for all primary pollutants in Kuala Lumpur City Centre clearly indicated that the concentration of particulate matter decreases with reduction of traffic volume in the city. The average mean concetration for CO during the BAU runs are ranging at 861-1439 μg/m³ compared to during 30% traffic reduction run at 834-1294 μg/m³. The average mean concentration for NO₂ during the BAU runs are ranging at 31.9-95.8 μg/m³ compared to during 30% traffic reduction run at 28.6-83.9 μg/m³. Average mean concentration for PM2.5 and PM10 during BAU runs are ranging at 30.4-43.7 μg/m³ and 41.4-65.9 μg/m³ respectively compared to during 30% traffic reduction run at 29.9-40.3 μg/m³ and 40.5-59.5 μg/m³ respectively. The average mean concentration for O₃ during the BAU runs are ranging at 3.81-28.6 μg/m³ compared to during 30% traffic reduction run at 5.05-30.7 μg/m³. This research demonstrates that traffic emission in urban area originates from vehicle emission and reduction of traffic volume in the city contributes to reduce the concentration of particulate matter pollution that is harmful to the environment and human health.

Study Design: Cross-sectional. Purpose: Clinical outcome study comparing the Copenhagen Neck Functional Disability Scale (CNFDS) and modified Japanese orthopedic association (mJOA) assessment scales in patients with cervical spondylotic myelopathy (CSM). Overview of Literature: Comparison of instruments that measure patient-reported outcomes is needed. Methods: A cross-sectional analysis was conducted. Ninety five patients with CSM were entered into the study and completed the CNFDS and the mJOA preoperatively and postoperatively. Correlation between the CNFDS and the mJOA was evaluated preoperatively and at the end of follow-up. Responsiveness to change of CNFDS and mJOA was also assessed. Clinical outcomes were also measured with the recovery rate of mJOA score at end of follow-up. Results: The mean age of patients was 58.2 (standard deviation, SD=8.7) years. Mean follow-up was 2.1 years (range, 1 to 4 years). The mJOA correlated strongly with the CNFDS score preoperatively and postoperatively (r =–0.81 and –0.82, respectively; p <0.001). The CNFDS and the mJOA were able to detect changes after the surgery (p <0.001). The mean mJOA recovery rate was 51.8% (SD=13.1%). Conclusions: Surgery for the treatment of patients with CSM is an efficacious procedure. CNFDS and mJOA scores have a strong correlation in measuring disability among CSM patients.

In this study, a selected c-aminobutyric acid (GABA)-rich Malaysian strain Aspergillus oryzae NSK was collected from soy sauce koji. The strain was used to explore the effect of using renewable native sugar syrup, sugarcane, nipa, and molasses as fermentable substrates for developing a novel functional GABA soy sauce. We evaluated the strain using the chosen native sugars for 7 days using shake flask fermentation at $30^{\circ}C$. The results showed optimum GABA concentration was achieved using cane molasses as the fermentable substrate (354.08 mg/L), followed by sugarcane syrup (320.7 mg/L) and nipa syrup (232.07 mg/L). Cane molasses was subsequently utilized as a substrate to determine the most suitable concentration for A. oryzae NSK to enhance GABA production and was determined as 50% g/L of glucose standard cane molasses. Our findings indicate that cane molasses can be used as a GABA-rich ingredient to develop a new starter culture for A. oryzae NSK soy sauce production.

A Steel Plate Shear Wall (SPSW) is a lateral load resisting system consisting of an infill plate located within a frame. When buckling occurs in the infill plate of a SPSW, a diagonal tension field is formed through the plate. The study of the tension field behavior regarding the distribution and orientation patterns of principal stresses can be useful, for instance to modify the basic strip model to predict the behavior of SPSW more accurately. This paper investigates the influence of torsional and out-of-plane flexural rigidities of boundary members (i.e. beams and columns) on the buckling coefficient as well as on the distribution and orientation patterns of principal stresses associated with the buckling modes. The linear buckling equations in the sense of von-Karman have been solved in conjunction with various boundary conditions, by using the Ritz method. Also, in this research the effects of symmetric and anti-symmetric buckling modes and complete anchoring of the tension field due to lacking of in-plane bending of the beams as well as the aspect ratio of plate on the behavior of tension field and buckling coefficient have been studied.
