Aims: This study was conducted to detect the impact of dry cupping therapy on acupuncture point P6 in alleviating nausea and vomiting symptoms during pregnancy.

Study Design: Randomized control trial.

Place and Duration of Study: This study was conducted in Outpatient Clinic of Obstetrics Department at Sidi Salm Hospital from March, 2016 to January, 2017.

Methodology: Randomized controlled study, 30 pregnant females, their age ranged from (18-30) years, 7- 14 weeks of gestation and their body mass index not exceeds 30 kg/m2. They were randomly divided in to two equal groups (A & B). Both groups were advised to change their life style, divided their diet on five or six meals, avoid spicy or fatty food and advised to take vitamin B6 tablet once daily. In addition to dry cupping on acupuncture point P6 in group A. Both groups were evaluated by pregnancy unique qualification of emesis and nausea questionnaire (PUQE) at the beginning of the study and after 2 weeks.

Results: There was significant reduction in frequency of nausea and vomiting between both groups at post treatment (p<0.05) and this significant reduction in favor to group A. Also there was improvement in the quality of life between both groups at post treatment (p<0.05) and this significant increase in favor to group A.

Conclusion: Dry cupping on acupuncture point pis a simple, safe and easy method used in treatment of nausea and vomiting symptoms during pregnancy.

In this paper we are investigate in the evolution equation p(x)- laplacian with the initial boundary value question. We translate the parabolic equation into the elliptic equation by using a finite difference method, and then the existence and uniqueness solution are obtained. The blow-up property is shown, by using the energy method. We perform, using Matlab (Ode45 subroutine), some numerical experiments just to illustrate our general results.

Many researches have been devoted for studying poly(vinyl alcohol) (PVA) and hydroxypropyl cellulose (HPC) and their blends as important promising biomaterials. In the present work, thin films of pure PVA, pure HPC and their PVA/HPC blends were prepared using the solution casting method. The mechanical properties of the prepared thin films such as stress-strain curve, tensile modulus and tensile strength as well as elongation at break were investigated. The obtained results show that there is an increase in the elastic range and decrease in the hardness of the resulting blends by increasing the concentration of HPC due to the different molecular morphology. In addition, the range in which it would responds elastically to external stress was decreased to some extent.

DOI: 10.9734/BJAST/2017/32187

Aims: The study examines the effect of capital cost and operating cost on some selected quarries within North Central Nigeria.

Study Design:  Survey design was used in designing the questionnaire used for collecting data from the selected quarries.

Study Area and Methodology: Twenty four quarries were selected in North- Central Nigeria for this study. Sixteen of these quarries were for commercial purposes while eight were for construction purposes. A total number of one hundred and fifty-five questionnaires were randomly distributed to the workers and managements of the various quarries to collect data on the quantity of granite rock blasted per month, cost of drilling accessories used, cost of explosives used, cost of maintenance of plant/equipment and cost of manpower. Net Present Value (NPV) and Internal Rate of Returns (IRR) were the two economic evaluation data analyses used for the study because they rely on the time value of money.

Results: The result shows that Majok quarry, Cafon quarry, Rock bridge quarry, Academ quarry, Trans Engineering and Sinac granite quarry are not doing well as their internal rate of returns falls short of the annual internal rate of returns of 20%. This indicates that the companies could not break even as they failed to cover the average operating cost.

Conclusion: The study noted that it is not only huge capital cost that determine the production cost of aggregates, rather, such measures as the size of the jaw of the crushing plant, appropriate spacing and burden drilling plan are very important to guide against the extra operating cost of secondary blasting.

The lift and drag coefficient plots for any airfoil provides a means for measuring its aerodynamic characteristics. These are very useful in deciding if a particular airfoil is appropriate for any particular application area. This study computationally predicts how the lift coefficient, drag coefficient and drag polar derived for the aerodynamic flow over the NACA 4412 airfoil vary with angles of attack. The effect of varying Reynolds number on the aerodynamic characteristics was also investigated. The finite-volume based computational fluid dynamics code; ANSYS Fluent was used to solve the continuity equation, the Reynolds Averaged Navier-Stokes equation and the turbulence transport equations governing the flow. For the range of Reynolds number considered, flow was taken as incompressible, steady and two-dimensional. Simulations were run for angles of attack ranging from -10° to 18° with an interval of 2° and for a Reynolds number range of 1.0 x 106 to 13.0 x 106. Results at a given Reynolds number revealed a steady variation between lift coefficient and angle of attack within the pre-stall region and a gradually increasing curve for the drag coefficients. A constant stalling angle at 14° with gradually increasing value for the maximum lift coefficient was recorded as the Reynolds number increased. The drag polar was also found to be constant at 6° for all the ranges of Reynolds number. The results obtained showed that numerically solving for flow problems is a valid approach for obtaining the aerodynamic characteristics of an airfoil since the results were compared with data from wind tunnel tests.

DOI: 10.9734/BJAST/2017/33142

Blocks are widely used in construction industry for both load and non-load bearing walls, blocks are of different forms and shapes and the most common is hollow sandcrete blocks. Glass wool fibre is an industrial waste product which can be turned to a useful material in the construction industry. The effect of glass wool fibre on the strength properties of hollow sandcrete blocks was investigated.

Sieve analysis was done on the sand used. The batching of the materials were done by weight and the mix ratio used was 1:8 with an average water-cement ratio of 0.5. Block samples of 150×225×450 mm (6” block) were produced by hand moulding process. Glass wool fibre at 0%, 5%, 10%, 15% and 20% of cement were added to the mix and compressive strength test was done by the ADR Touch 1500 kN Compression Testing Machine on the block samples.

The Coefficient of Curvature (Cc) and Coefficient of Uniformity (Cu) of the sand were 1.04 and 4.47 respectively, the sand is well graded. The compressive strength test results of an average of 0.6, 0.8, 0.9, 1.1 and 0.4 N/mm2 were obtained respectively.

It was concluded that the compressive strength of the hollow sandcrete block gradually increased and attained the maximum strength at 15% addition of glass wool fibre which is 33% increase in the compressive strength, where the weight also decreased by 1.6%. Therefore, the block at 15% addition of glass wool fibre can be used for non-load bearing walls such as fence and partition walls in building construction.

The dramatic development of multimedia technology, and the use of image capturing equipment have increased the number of images worldwide which are needed to be available. For this purpose, there are many general processes of image retrieval of which are Text based image retrieval (TBIR), Content based images retrieval (CBIR). While retrieving images using text-based approach, all the images are needed to be annotated manually which is time consuming. To be get the image retrieval process rid of this complexity content based approach was introduced. There are several processes of CBIR system. Here a new method of CBIR has been proposed which is based on both texture features and color features. Here, HSV histogram, Autocorrelogram, and color moment have been used to extract the color features. On the other hand, for the purpose of the extraction of texture features, Wavelet transformation, and Gabor wavelet transformation have been used. For implementing the process, a GUI has been designed at first. For every category searching, the elapsed time is calculated, and compared with the existing methods.
