Rainwater Harvesting and Its Impact on Farming Systems

Landless, small holders and other poors supplement their livelihood and adapt to climate change by grazing, stall feeding with crop residues and fodder cultivated under rainfed and irrigated conditions. Improving productivity by conserving rainfall, ground water recharging, harvesting and recycling of rainwater especially in degraded open access or shared land with community participation was quite successful over a wide range of precipitation and ecological situations. Various types of trenches, bunding, vegetative barriers, gully plugs, ponds, check dams, land slides and mine spoils stabilization etc. retained more soil moisture, seeds, vegetative propagules etc. in situ and prevented soil erosion. It regenerated and enhanced biomass production of grasses, other forages, crop residues and environmental externalities. It reduced socially undesirable seasonal migration of herders by 35-100%, number of goats, dependency on open or common access resources and increased bovine population, stall feeding and milk productivity. Limited irrigation with harvested and recharged rainwater led to farm diversification, more availability of crop residues and better income. Climate change has reduced number of rainy days, increased intensity and frequency of run off producing events and can be converted into still better opportunities of adaptation by rain water harvesting

The Role of Precedent in Defining Res Judicata in Investor–State Arbitration

As international arbitration, and investment arbitration in particular, becomes more prevalent, the risks of doctrinal fragmentation also increase, in part driven by the disparate treatment of the doctrine of res judicata throughout most jurisdictions, and in the arbitration context. Notwithstanding the general consensus regarding the broad contours of res judicata and its firm position as a principle of international law, there is little agreement regarding how it is to be administered. These developments threaten to undermine the international arbitration system, wresting from it normative legitimacy. The U.S. common law version of res judicata, which is distinct from res judicata as developed in many civil law jurisdictions, may serve as a substantial conceptual foundation upon which civil law and other common law res judicata precepts may merge to fashion a uniform doctrine applicable in international arbitration that is expansive, substantive/transactional-based as to criteria, and non-formalistic in its application so as to avert and discourage the doctrine’s circumvention through the use of legal fictions

Catatonia with GABAA receptor antibodies

A 22-year-old African woman developed acute behavioural change, against a background of sickle cell disease with strokes requiring a ventriculoperitoneal shunt. She alternated between mutism with prolonged staring and posturing, and a state of agitation with elation and echolalia. Cerebrospinal fluid (CSF) protein was elevated and electroencephalogram showed mild slowing with bitemporal slow and sharp waves. We suspected catatonia secondary to possible autoimmune encephalitis but her condition persisted despite intravenous methylprednisolone. After identifying a positive serum anti-gamma-aminobutyric acid-A (GABAA) antibody, treatment with intravenous immunoglobulin, oral corticosteroids and rituximab led to gradual improvement. Patients with catatonia may show reduced GABAA receptor density and there are two other reports of catatonia with anti-GABAA antibodies. This patient's treatment response supports the antibody's causative role

Synthesis and Characterization of ZnO-MMT Nanocomposite for Antibacterial Activity Studies

ZnO oxide Nanoparticle and ZnO oxide with Montmorillonite nanocomposite were prepared by an environmentally friendly, efficient, and  inexpensive method that was synthesized using the chemical method. ZnO nanoparticles as an effective antibacterial material were immobilized on the surface of montmorillonite (MMT). The objectives of this paper are to summarize our research activities in (a) developing processes to dispersenanomaterials (undoped and doped zinc oxide powders) in the polymers matrix, (b) using X-ray diffraction (XRD), Fourier Transform Infra-Red Spectroscopy (FT-IR), Scanning Electron Microscopy (SEM) and Thermo Gravimetric Analysis (TGA) techniques to characterize polymer matrix structures, (c) studying structure-property relationship of these types of new materials, and (d) evaluating the antibacterial performance of these materials for different applications. The results showed that the ZnO nanocomposite was uniformly dispersed in the polymer matrix and the particles remained their average size (20 - 150 nm) before incorporation into the polymer matrix.

On the shock behaviour and response of Ovis Aries vertebrae

When investigating a biological system during shock loading, it is best practice to isolate different components to fully comprehend each individual part [1,2] before building up the system as a whole. Due to the high acoustic impedance of bone in comparison to other biological tissues [3] the majority of the shock will be transmitted into this medium, and as such can cause large amounts of damage to other parts of the body potentially away from the impact area
