Climate Change and Sustainable Management of Salinity in Agriculture: Crimson Publishers

Climate Change and Sustainable Management of Salinity in Agriculture by Gurbachan Singh in Research in Medical & Engineering Sciences


There has been a steady increase in the emission of greenhouse gases like carbon dioxide, methane and nitrous oxide in the environment. Agriculture is reported responsible for up to almost half of all methane emissions. The climate change predictions over India indicate that temperature rise is likely to be around 3”C and rainfall increase is expected by 10-20 per cent over central states of India by 2100 A.D. The climate change triggered frequency of weather related events like floods, droughts, frost, cold and heat waves has considerably increased during last two decades. Continuation of such trends associated with rise in temperature is expected to melt ice, glaciers, re-distribute water flow in rivers, raise sea levels, sub-merge coastal habitats, islands, generate tsunamis and dislocate human and livestock settlements. Predicted spatial redistribution of precipitation, droughts, floods and water balance will change land use, pests, diseases and other ecological parameters. These changes will necessitate the need to devise research strategies to deal with predicted changes to sustain agricultural productivity and to achieve food and nutritional security in 21st century.

The Malachite Wen-Myeloid Sarcoma- Crimson Publishers

The Malachite Wen-Myeloid Sarcoma- Crimson Publishers   Contingent to World Health Organization (WHO) classification, myeloid sarcoma is denominated as a tumefaction comprised of myeloblasts amalgamated at an anatomical site divergent from the bone marrow which engenders distortion of normal tissue architecture. Generally, myeloid sarcoma is contemplated to be equivalent to and concurrent with acute myeloid leukaemia (AML), although lesions may occur in isolation. Additionally designated as granulocytic sarcoma, chloroma or extramedullary myeloid tumour, myeloid sarcoma categorically represents as a distinct tumefaction associated with architectural effacement of circumscribing soft tissue. Myeloid sarcoma may emerge as a de novo lesion or manifest as therapy related myeloid neoplasm or as disease progression within myeloproliferative neoplasm (MPN), myelodysplastic syndrome (MDS) or myelodysplastic / myeloproliferative neoplasm (MDS / MPN). In contrast, leukaemia cutis (LC) is...

Stimulus Activated Shape Switching in Shape Memory Materials with Tailor Able Start/Finish Temperature/ Time - Crimson Publishers

Stimulus Activated ShapeSwitching in Shape Memory Materials with Tailor Able Start/Finish Temperature/Time by Wei Min Huang* in Research in Medical & Engineering Sciences The shape memory effect (SME) refers to the phenomenon of shape recovery in a severely pre-deformed material , but only when a right stimulus is applied. The materials with the SME are called shape memory material (SMM), and typical stimuli include heat, chemical (including water/moisture), light, etc. Right now, the family of SMM has expended significantly, and covers a range of different types of materials, including alloy, polymer and ceramic etc. In general, the SME process includes two steps. The first step is to program the piece of SMM into a temporary shape (known as the programming process); and the second step is to apply the right stimulus for recovery (called the recovery process) with or without constraint applied. https://crimsonpublishers.com/rmes/fulltext/RMES.000515.php For mo...
