The dynamic behavior of infrastructure development has opened a wide area for research in construction management in general, and maintenance management in particular, globally. Ready mix concrete, which is mostly preferred nowadays, is loaded in a transit mixer, and is transported to the construction site. The concrete is delivered to the construction point by means of a concrete pump. Life of the concrete pump can be enhanced and hence capacity of the plant using effective preventive maintenance. In this paper, optimal time for replacement for some critical components has been established using the approach of reliability centered maintenance. The paper includes the reliability assessment and the details of the effectiveness of maintenance on the system under investigation are reported in the paper.

Biotechnological applications provide us significant economic and social benefits in areas such as health, agriculture, the environment and industry. Considering its advantages and potent capability innovation in genetic engineering and biotechnology has been extended protection of patent. Almost every international legal instrument has accepted the role of biotechnological inventions in growth of the society. However, when researchers and corporate houses moved for getting patent for higher life forms it was opposed on the ground that it will be in violation of traditional fundamentals of patent laws. Even the claim of patent was denied by patent offices for the process relating to study of growth of cancerous cell in the mouse. This paper is an attempt to assess the effect of patenting of higher life forms and also to identify the philosophical basis thereto. The researcher supports the corollary drawn by European Courts for the patenting of higher life forms.

Pericardial effusions are frequent conditions, there etiologies are dominated by: acute infarction of the myocardium, myocarditis, metabolic disorders, certain neoplasias, inflammatory or infectious diseases, traumatisms and cardiac surgery. The dissection of the aorta is one of the rare conditions; it is primarily due to a rupture of the ascending aorta and presents diagnostic difficulties.We report the case of an 80 years old male, with a medical history of chronic smoking stopped since 2 years, a recently discovered of hypertension, a surgery for an inguinal hernia and appendicitis. Presented in our formation with an expansive pericardial effusion; clinical examination found an asymmetry of upper extremity blood pressures, thoracic radiography showed an unrolled aorta. Thoracic CT scan has allowed the diagnosis of aortic dissection type 1 of De Bakey classification and type A of Stanford. The patient was referred to a cardiovascular surgical center where he benefited of the replacement of the dissected aorta by a prosthetic tube while preserving his native valve, with positive outcomes.Our clinical observation aim to discuss diagnostic of dissection to any pericardial effusion or pericarditis, even in the absence of usual symptoms, in order to avoid any diagnostic delay. In our methodology we have overview a systemic review included PuBMed; all of our results in discussion are not based to basis recommendations because of the uncommun presentation having problem in extrapolating strong evidence but we have reporting somes basis of experts’ opinion.

This study presents the application of geophysical wireline logs for porosity and permeability characterization of “AHO” field, Eastern Niger Delta, Nigeria. The main objective of the study is to understand the effects of petrophysical parameters on reservoir quality of the field. A suite of wireline logs (gamma ray, resistivity, and density logs) from seven wells of “AHO” field were analyzed. Gamma ray log motif was used to delineate lithologies, delineate the top and base of reservoir units, and consequently determined petrophysical parameters using standard relations. The reservoir properties evaluated include porosity, permeability and fluid saturation. The study identified six (6) reservoir sand bodies (A, B, C, D, E, and F) delineated from their tops and bases at depth 3000ft – 5280ft. Petrophysical evaluation computed across the reservoir shows porosity ranging from 32.08 % to 37.47%; permeability 3067.72md to 4051.06md and average hydrocarbon saturation of 71.1% to 77.6% for reservoirs A-F. Plots of depth versus porosity shows that porosity decreases with increasing depth, and porosity versus permeability shows that permeability increases as porosity increases. From the analysis, the reservoirs show excellent porosity and permeability. The reservoirs in AHO field are of high quality to enhance hydrocarbon accumulation and production.

The present investigation was carried in the experimental test organism, Mugil cephalus exposed to cadmium, copper, lead and zinc in acute and chronic toxicity test. The raw survival data from the acute toxicity test were utilized for the prediction of No Observed Effect Concentration (NOEC). The data obtained from the laboratory and the predicted endpoints were then compared with the heavy metal concentrations in the Ennore creek. Acute toxicity tests revealed that fingerlings were sensitive to copper, followed by cadmium, lead and zinc, and the 96-hour LC₅₀ values were 4.29 mg/l Cd, 2.29 mg/l Cu, 6.90 mg/l Pb and 7.92 mg/l Zn. Experimental NOEC had strong correlation with the predicted NOEC at P=0.0001 and P=0.005. Correlations were significant at P<0.01 (2-tailed), (? =0.05). The predicted and the experimental NOEC values were lower than the heavy metal concentrations in the Ennore creek. The concentrations of heavy metals in the Ennore creek were relatively higher than the NOEC values for juvenile marine organisms tested in the laboratory. Hence, there exists threat for survival and an urgent need for the enactment and enforcement of stringent laws to control the heavy metal pollution in the Ennore creek as well as to protect estuarine and marine bio-resources.

An electronic device based on capacitive sensor was developed to predict the volume of banana fruit. This system, which is used for volume measurement has four components: a rectangular parallel plate capacitor, electronic circuitry, microcontroller, and display unit. After calibrating the electronic system, the results were verified with calibrated curve by means of linear regression and paired t-test. The coefficient of determination (R2) for 1, 10, 100, and 450 kHz frequencies were obtained as 0.934, 0.88, 0.932, and 0.935, respectively. The acquired P-values for 1, 10, 100, and 450 kHz frequencies were 0.541, 0.448, 0.132, and 0.064. The results indicated that banana fruits size has no effect on the accuracy of the computed volume. The results for banana fruits showed that the predicted volume and actual volume are highly correlated and this method is ideal for determining the volume of fruits and it can be developed for other fruits, too.

The marine biosphere is one of the richest habitats of microorganisms. Marine microbes particularly bacteria are considered for their secondary metabolites and enzymes with novel properties. The Marine Soil Microbial isolates were screened for potential producers of L-asparagines using a phenol red indicator and growth medium. The isolates were characterized by biochemical tests and found to belong to Bacillus sp. We performed random amplification of polymorphic DNA (RAPD) analysis on five strain of Bacillus sp. Random primers were used for the PCR. Electrophoresis on denaturing acrylamide gels improved RAPD reproducibility and increased the band number. The primer of OPU series gave reproducible results and band profiles.

Diabetic neuropathy is a type of nerve damage that is seen in people who have diabetes. This makes it difficult for the nerves to carry messages to the brain and parts of the body. Diabetic neuropathy can result in numbness or painful tingling in different parts of the body. Diabetic neuropathy can affect any part of the nervous system. This nerve disorder should be suspected in all patients with type 2 diabetes and in patients who have had type 1 diabetes for more than five years. About 60 to 70 percent of people with diabetes have some form of neuropathy. People with diabetes can develop nerve problems at any time, but the risk increases with age and duration of the disease. The highest rates of neuropathy occur among people who have had diabetes for at least 25 years and among people who have trouble controlling their blood sugar levels, as well as those with high levels of blood fat and blood pressure and those who are overweight. Diabetic neuropathy is long-term damage to the nerve fibres. It happens when high blood glucose levels are present over several years. In diabetes, the form it usually first takes is reduced sensation in the feet. The nerve damage affects each foot equally and eventually spreads up the legs. Poor sensation in your feet makes them more prone to injury. Combined with poor circulation this can easily lead to ulcers and infections.

Collaborative Sensor Fault Detection (CSFD) technique is used to detect the faults in the sensor nodes of a fusion center in a robust distribution estimation scheme. This technique can identify the faulty nodes efficiently and improve the accuracy of the estimates. ASIC implementation is used to design the fusion center based on their applications. In this approach there occurs some limitations such as computational complexity; hardware implementation is quite complex and high power consumption. In order to overcome these difficulties, we modify CSFD and propose an ECSFD scheme. ECSFD is simple and requires lower computational complexity, thus lower hardware cost and power consumption can be achieved. Furthermore, ECSFD achieves almost the same performance as CSFD. VLSI architecture is developed for hardware implementation.

Waste is an unavoidable by product of human activities. All the human activities ie., domestic, commercial, industrial, healthcare, organizations, generates solid wastes that are normally discarded as useless or unwanted. The wastes generated from these activities of more advanced society produce more complex and heterogeneous wastes because of living standards and changing food habits. With rising urbanization, change in life style and improving living standards in cities; have led to increase in per capita waste generation and complexity of generated waste in the recent years. The problem in cities lies not only in the quantity but also in the quality and composition of the wastes, which have changed from being dense and almost entirely organic to voluminous and increasing non-biodegradable with higher percentage of toxic substance. The exponential growths of human population & resource consumption have left outstripped the ability of the natural environment to assimilate it and municipal authorities to manage it. Increasing migration, high-density population will make waste management a difficult issue to handle in the near future.
