Donkey traction, use and welfare needs at Daman region of Dera Ismail Khan, Pakistan

  This paper reviews donkey utilization in the livelihood of people in the arid zone of Dera Ismail Khan and adjoining areas of Khyber Pakhtoon Khawa, commonly known as Daman. The physical atmosphere of Daman region is rather harsh and the annual rainfall is low. The lands are sandy to muddy or mixed, very poor in nutrients and relatively salty. Most of the region is a broad plain approximately 500 to...

A review on the fabrication techniques of functionally graded ceramic-metallic materials in advanced composites

    Whenever two or more dissimilar materials are bonded, large jump in the stresses occurred at the interface during the fabrication will leads to the delamination and poor load-bearing performance on the final structures. Functionally graded material (FGM) which has compositional and microstructure gradient along its thickness was introduced to be a great solution to this...

Developing new exchanger for removal of inorganic arsenic species from groundwater

    A new Dowex monospher-BBr exchanger was prepared by the reaction between the conjugated base sulfonic acid [R-S-O3]- of DOWEX MONOSPHERE MR-450 UPW and the strong Lewis acid BBr3 forming adduct (coordinated complex) [(R–S-O3)2 BBr3]+3. The prepared resin is a promising exchanger for the removal of inorganic arsenic species from underground water. More than...

Linear thermoelastic analysis of a functionally graded (FG) rotating disk with different boundary conditions using Adomian’s decomposition method

    Linear thermoelastic formulation of a functionally graded rotating disk is studied in the present paper. Thermoelastic solution of a rotating disk, due to the nonhomogenous terms, needs more mathematic operation and the solution of the governing equation is more complicated. In the present paper, thermo elastic formulation of a functionally graded rotating disk is presented...

Macroscopic and microscopic findings of infant lung in case of live or still birth

    In the case of a newly born infant, either stillborn or found dead, the state of the lungs is of particular forensic interest. The aim of this study was to determine whether lungs are adequate for pathological comment about stillbirth or live birth of an infant. In order to evaluate the relevance of 171 autopsy reports of infants, macroscopic and microscopic findings, and body...

Simulation of the adaptive neuro-fuzzy inference system (ANFIS) inverse controller using Matlab S-function

    In this paper, for the purpose of simulating the mathematical model of adaptive neuro-fuzzy inference system (ANFIS), we use Matlab/Simulink environment with its powerful S-functions. The simulated model of ANFIS network can be then used to make the simulation of the identification and the control of linear or nonlinear systems. Created Simulink block of ANFIS give...

Theoretical analysis on the laminar flow of an elastico-viscous fluid between a moving elliptic plate with constant injection and the ground

    A theoretical study is presented for the problem of injection of an elastico-viscous fluid through a moving elliptic plate. The governing equations are reduced to a system of nonlinear ordinary differential equations by means of appropriate transformations for the velocity components. The resulting boundary value problem is solved numerically using the Matlab solver singular...

Experimental and numerical stress analysis of glass fiber-reinforced polymer (GFRP) -stiffened shells with cutout under axial loading

    In the present study, the stress analysis of thin-walled glass fiber-reinforced polymer (GFRP) cylindrical shells with and without cutout subjected to axial loading was carried out by using experimental and finite-element method. The effect of cutout type on the stress distribution of the shell was described. In the experimental procedure electrical strain gauges...

Perceptions of rural consumers on the quality of mutton in the Eastern Cape Province, South Africa

    The objective of the study was to determine the perceptions of consumers from the Eastern Cape Province of South Africa on the quality of mutton. A survey was conducted on 215 consumers from five different municipalities in the Eastern Cape province of South Africa. Data was gathered from interviewed consumers at the point of purchase, or when they left the shops. Door to door...

Mechanism(s) of humic acid induced beneficial effects in salt-affected soils

    There is enough evidence that humic acid (HA) helps to enhance crops yield by promoting certain physical, chemical and biological activities in soil-plant system. Indigenously produced coal derived, HA was added to saline-sodic silty clay soil to determine its effects on activities of alkaline phosphatase, urease, microbial activities, cation exchange capacity and moisture...

Pre-germination hydration affects seed performance in bambara groundnut

      In a study to determine the response of local bambara groundnut (Vigna subterranea (L.) Verdc.) germplasm to seed enhancement, seeds were subjected to hydration (12, 75 and 93% RH) to influence pre-germination water activity (aw) and subsequent germination and seedling establishment. This study also reports on seedling characteristics 28 days after sowing under...
