In this paper we will compute a new algorithm for new graph which its vertex is a graph.

This paper presents some important operational matrices of fourth kind Chebyshev wavelets. New formula of operational matrix of derivative for fourth kind Chebyshev polynomials is first obtained and then operational matrices of derivative and integration of the fourth Chebyshevwavelets basis are derived. The proposed results are of direct interest in many applications.

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.
