Design and implementation of remotely monitoring system for pH level in Baghdad drinking water networks
Many people in the recent days have suffering from number of diseases due to unsafe and impure drinking water, especially in rural areas. As typical laboratory experiments and official water quality tests take considerable amount of time to obtain results and due to non availability of a simple device that can measure such water quality parameters in real time, therefore in this paper a remote pH level monitoring system for Baghdad drinking water system is proposed. A PH level sensing and monitoring nodes are distributed at different location. These nodes are proactively measured pH level of water and send data to the maintenance center to give them overall picture about pH level via global position system (GSM). This proposed system gives a robust, low-cost and effective method for the drinking water maintenance center to measure and monitoring the water quality in real time environment
Phosphate binding therapy in dialysis patients: focus on lanthanum carbonate
Hyperphosphatemia is an inevitable consequence of end stage chronic kidney disease and is present in the majority of dialysis patients. Recent observational data has associated hyperphosphatemia with increased cardiovascular mortality among dialysis patients. Dietary restriction of phosphate and current dialysis prescription practices are not enough to maintain serum phosphate levels within the recommended range so that the majority of dialysis patients require oral phosphate binders. Unfortunately, conventional phosphate binders are not reliably effective and are associated with a range of limitations and side effects. Aluminium-containing agents are highly efficient but no longer widely used because of well established and proven toxicity. Calcium based salts are inexpensive, effective and most widely used but there is now concern about their association with hypercalcemia and vascular calcification. Sevelamer hydrochloride is associated with fewer adverse effects, but a large pill burden and high cost are limiting factors to its wider use. In addition, the efficacy of sevelamer as a monotherapy in lowering phosphate to target levels in severe hyperphosphatemia remains debatable. Lanthanum carbonate is a promising new non-aluminium, calcium-free phosphate binder. Preclinical and clinical studies have demonstrated a good safety profile, and it appears well tolerated and effective in reducing phosphate levels in dialysis patients. Its identified adverse events are apparently mild to moderate in severity and mostly GI related. It appears to be effective as a monotherapy, with a reduced pill burden, but like sevelamer, it is significantly more expensive than calcium-based binders. Data on its safety profile over 6 years of treatment are now available
Enhancing the quality of service for real time traffic over optical burst switching (OBS) networks with ensuring the fairness for other traffics
Optical burst switching (OBS) networks have been attracting much consideration as a promising approach to build the next generation optical Internet. A solution for enhancing the Quality of Service (QoS) for high priority real time traffic over OBS with the fairness among the traffic types is absent in current OBS ’ QoS schemes. In this paper we present a novel Real Time Quality of Service with Fairness Ratio (RT-QoSFR) scheme that can adapt the burst assembly parameters according to the traffic QoS needs in order to enhance the real time traffic QoS requirements and to ensure the fairness for other traffic. The results show that RT-QoSFR scheme is able to fulfill the real time traffic requirements (end to end delay, and loss rate) ensuring the fairness for other traffics under various conditions such as the type of real time traffic and traffic load. RT-QoSFR can guarantee that the delay of the real time traffic packets does not exceed the maximum packets transfer delay value. Fur- thermore, it can reduce the real time traffic packets loss, at the same time guarantee the fair- ness for non real time traffic packets by determining the ratio of real time traffic inside the burst to be 50 – 60%, 30 – 40%, and 10 – 20% for high, normal, and low traffic loads respectively
Analysis of Marketing Channel and Market Structure of Dried Fish in Maiduguri Metropolis of Borno State, Nigeria
The study examined channel and market structure of dried fish in Maiduguri Metropolis of Borno State, Nigeria. Data were obtained using structured questionnaire. Three (3) major dried fish markets were purposely selected out of the seven (7) markets in the study area to reflect areas where dried fish sellers are predominantly found. A total of 100 respondents from the three (3) markets were randomly selected for the study. Descriptive statistics, Ginni coefficient, least square simple regression and budgetary techniques were used as analytical tools. The result reveals that marketing channel is divided into wholesalers and retailers of fresh and processed fish (dried fish). The finding also indicates that the values of Ginni coefficient were (0.5478) and (0.5252) for wholesalers and retailers, respectively. And the dried fish market had non competitive behaviour with monopolistic nature. The finding also reveals that (82%) of the marketers engaged in marketing Grade C dried fish products. The result of economies of scale reveals that the coefficient of wholesalers was (-0.005) while that of retailers was (-0.741) and are all negative but, statistically significant at 1% and 5%, respectively. It was recommended that local dried fish marketers should be organized into cooperative groups and government should provide adequate infrastructural facilities such as good road net work and market facilities.

Identification Pseudomonas aeruginosa by 16s rRNA gene for Differentiation from Other Pseudomonas Species that isolated from Patients and environment
Pseudomonas aeruginosa is a common and major opportunistic human pathogen, its causes many and dangersinfectious diseases due to death in some timesex: cystic fibrosis , wounds inflammation , burns inflammation , urinary tract infection , other many infections otitis external , Endocarditis , nosocomial infection and also causes other blood infections (Bacteremia). thereforebecomes founding fast and exact identification of P. aeruginosafrom samples culture very important.However, identification of this species may be problematic due to the marked phenotypic variabilitydemonstrated by samples isolates and the presence of other closely related species. To facilitate species identification, we used 16S ribosomal DNA(rRNA) sequence data toidentify genus- and species-specific 16S rRNA signature sequences,its account a stable part of the geneticcode. Based on these sequences we designed simple, rapid, and accurate PCR assays that allow the differentiation of P. aeruginosa from Pseudomonas species and other pathogen genus ,also this test considered as the most specific than the other diagnostic tests like API (20) which give 70% while the 16SrRNA test give more than 90 %
Study of functional outcome of muller type C distal femur fracture treated with locking compression plate
Background: To evaluate the functional outcome of Muller type C distal femur fracture treated with locking compression plate (LCP).
Methods: This prospective study was carried out at Al-Ameen medical college and hospital, Vijayapura. Forty patients (24 males and 16 females) with Muller type C distal femur fractures were enrolled in our study. Patients were treated with open reduction and internal fixation with LCP. They were followed up for 9 months with clinical examination and serial x-rays. The functional outcome was evaluated using Neer’s scoring system.
Results: Forty patients who completed follow up of 9 months were included. There were 18 muller type C1, 14 muller type C2 and 8 Muller type C3 fractures. The functional evaluation with Neer’s scoring system was excellent in 8 patients, good in 20 patients, fair in 8 patients and poor in 4 patients. Complications observed were difficulty in reduction, superficial infections, knee stiffness and limb length discrepancy.
Conclusions: The LCP is a safe and effective tool to manage these difficult fractures as we had no incidence of implant failure, delayed union, non-union and revision surgery except that we had knee stiffness as commonest complication which can be tackled by early surgery, surgical expertise, meticulous soft tissue handling and vigorous early knee mobilisation.
Hepatoprotective Effects of Orthosiphon stamineus Extract on Thioacetamide-Induced Liver Cirrhosis in Rats
Orthosiphon stamineus as medicinal plant is commonly used in Malaysia for treatment of hepatitis and jaundice; in this study, the ethanol extracts were applied to evaluate the hepatoprotective effects in a thioacetamide-induced hepatotoxic model in Sprague Dawley rats. Five groups of adult rats were arranged as follows: Group 1 (normal control group), Group 2 Thioacetamide (TAA) as positive control (hepatotoxic group), Group 3 Silymarin as a well-known standard drug (hepatoprotective group), and Groups 4 and 5 as high and low dose (treatment groups). After 60-day treatment, all rats were sacrificed. The hepatotoxic group showed a coarse granulation on the liver surface when compared to the smooth aspect observed on the liver surface of the other groups. Histopathological study confirmed the result; moreover, there was a significant increase in serum liver biochemical parameters (ALT, AST, ALP, and Bilirubin) and the level of liver Malondialdehyde (MDA), accompanied by a significant decrease in the level of total protein and Albumin in the TAA control group when compared with that of the normal group. The high-dose treatment group (200 mg/kg) significantly restored the elevated liver function enzymes near to normal. This study revealed that 200 mg/kg extracts of O. stamineus exerted a hepatoprotective effect
