Health Professionals’ Roles In Animal Agriculture, Climate Change, And Human Health, Aysha Z. Akhtar, Michael Greger, Hope Ferdowsian, Erica Frank

Michael Greger, MD, FACLM

What we eat is rapidly becoming an issue of global concern. With food shortages, the rise in chronic disease, and global warming, the impact of our dietary choices seems more relevant today than ever. Globally, a transition is taking place toward greater consumption of foods of animal origin, in lieu of plantbased diets. With this transition comes intensification of animal agriculture that in turn is associated with the emergence of zoonotic infectious diseases, environmental degradation, and the epidemics of chronic disease and obesity. Health professionals should be aware of these trends and consider them as they promote healthier and more …

Grain Iron And Zinc Density In Pearl Millet: Combining Ability, Heterosis And Association With Grain Yield And Grain Size, Mahalingam Govindaraj

Mahalingam Govindaraj

Genetics of micronutrients and their relationships with grain yield and other traits have a direct bearing on devising effective strategies for breeding biofortified crop cultivars. A line × tester study of 196 hybrids and their 28 parental lines of pearl millet (Pennisetum glaucum (L.) R.Br.) showed large genetic variability for Fe and Zn densities with predominantly additive gene action and no better-parent heterosis. Hybrids with high levels of Fe and Zn densities, involved both parental lines having significant positive general combining ability (GCA), and there were highly significant and high positive correlations between performance per se of parental lines and …

Atomic, Crystalline And Powder Characteristics Of Treated Zirconia And Silica Powders, Mahendra Kumar Trivedi

Mahendra Kumar Trivedi

Zirconium oxide and silicon dioxide powders are selected and subjected to a non-contact Biofield energy known to be transmitted by Mahendra Kumar Trivedi. Particle sizes d50 and d99 showed up to 71.5 percent decrease indicating that the energy had caused deformation and fracture as if the powders have been subjected to high energy milling. This is also supported by increase in specific surface area up to 19.48 percent. In the present investigation Zirconium oxide and silicon dioxide powders are exposed to Bio-field. Both the exposed and unexposed powders are later characterized by various techniques. The treated powders when characterized by …

Managing China's Pastoral Lands: Current Problems And Future Prospects, Victor Roy Squires Dr

Victor Roy Squires Dr

China has the second largest area of pastoral land in the world, and these lands and their peoples play a very beneficial role in the global environment. Because of China’s huge population, rate of social reform, and economic development, the pastoral ecosystems are at a critical turning point. There is a conflict between national benefit and the land users (mainly herders) benefit. This paper introduces the scale of pastoral land, the history of its management institutions, past and current projects and programs, as well as the current framework of policy and law as relevant to land management.

Management Regimes And Its Impact On The Wetland Fisheries Management In Assam, Ganesh Chandra

Ganesh Chandra

Assam is endowed with copious aquatic wealth in the form of beels, swamps, ponds and rivers. The floodplain wetlands (beels) extending over one lakh hectare, constitute the most important fishery resource of the state. The beels are considered as one of the most productive ecosystems owing to their characteristic interactions between land and water system. These wetlands are the common property resource and under different management regimes. These wetlands are under various management regimes, i.e., private management (individuals and groups), fishermen cooperative management, Community-based fisheries management (decentralized management, Government works as facilitator) and open access. Most of the unregistered beels …

Connecting Through Consilience: Ecology, Society, Culture And Technology, Ruth Mirams, Alexander Hayes

Alexander Hayes Mr.

Amongst linguistic, cultural and geographic diversity, humanity is characterised by inquisitiveness, communication and a deep desire to connect with each other. Despite our advanced intelligence and technological capacity, we are creatures of nature - a species which occupies a habitat, depends on consumable resources and fragile in many ways. As a species, we currently face challenges including overpopulation, diminishing resources and habitat degradation. In essence, we are exhausting the resources we depend on. [1] Resource depletion, disruption, famine, growth and sustainability are all observable in other species and natural systems. Human societies and systems can be described through the same …

Jeffrey W Adelberg

Two clones of turmeric (Cucruma longa L.) were assessed nine times during a 28-day culture period in double phosphate MS liquid medium containing 2%, 4% and 6% sucrose. The phase of rapid shoot bud multiplication lasted for 21 days or less, in both clones in all media. The maximum multiplication rate was 3.4× at 20 and 19 days, with 3.9% or 4.7% initial sucrose concentration being optimal for the clones 9-3 and 35-1, respectively. Dry mass increased over the entire culture period and was greatest with 4.8% or at least 6% initial sucrose concentration for the two clones, 9-3 and …

Efficiency In Thin-Film Liquid System For Hosta Micropropagation, Jeffrey Adelberg

Jeffrey W Adelberg

Three varieties of Hosta (‘Striptease’, ‘Minuteman’ and ‘Stiletto’) at four densities (40, 80, 120 and 200 explants per litre) were micropropagated on semi-solid agar and a thin-film liquid system with intermittent wetting of plant tissue. The mechanics of wetting by a small wave front required a larger rectangular vessel (11 × 27=297 cm 2) compared to the common cylindrical baby food jar (18 cm 2). Plants multiplied more rapidly in the agitated thin-film system than on agar. Lower plant densities increased rates of multiplication in liquid, but had little or no effect on multiplication rate on agar. Increasing plant density …

Mitigation Site Soil Characteristics And The Effects Of Inoculation, Nursery Fertilizer Practices And Irrigation On Survival And Growth Of Mesquite (Prosopis Glandulosa) In The Coachella Valley, California, David A. Bainbridge, Marcelle M. Darby

David A Bainbridge

Prosopis glandulosa var. torreyana (mesquite, honey mesquite) is a small to medium sized leguminous tree that was once common in the low desert of California. Widespread destruction of mesquite woodlands in the Coachella Valley of southern California for fuel wood, agricultural and urban development, and urbanization has reduced once vast stands to isolated remnants. The rerouting and widening of Highway 86 in the Coachella Valley was a typical example of ongoing mesquite woodland removal. Despite the recognized need for mitigation, relatively little information on mesquite establishment in California is available. This research explored mesquite establishment by replanting on an abandoned …

Jeffrey W Adelberg

Unitized, nonselective mass cutting of Stage II Citrullus lanatus cv. Charlee (watermelon) plant tissue cultures has been achieved with various configurations and sizes of wire cutter devices. Time studies revealed that the wire cutters increased the productivity of the cutting function over conventional scalpel and forceps by a factor of 14, Total transfer productivity, including the manual functions of removing tissue from an initial culture vessel and filling (sorting and placing cut tissue segments) new vessels, was increased by a factor of 1,8, The square grid-type cutting devices yielded from 48 to 59% as many viable bud clusters per culture …

Approaching Mechanization Of Plant Micropropagation, Jeffrey Adelberg, R E. Young, A Hale, N D. Camper

Jeffrey W Adelberg

Investigations of materials and methods for growing plant tissue in a continual-flow, liquid nutrient medium as an alternative to semisolid agar medium have been made. Enhanced growth of plant tissue on microporouspolypropylene membranes floating on a liquid nutrient has been demonstrated. Moreover, in vitro plantlets on the microporous membrane are free from entanglement with the support matrix and readily available to mechanizedhandling. Trained growth of plantlets through polypropylene netting shows potential for mechanization by mass handling (separation, singulation, and transfer) of plant tissue cultures.

Mass Handling Of Watermelon Microcuttings, Jeffrey Adelberg, Y Alper, R E. Young, B B. Rhodes

Jeffrey W Adelberg

Modifications were made in the configurations of the unitizing, nonselective wire cutters used by Alper et al.(1992) for mass cuttings of Stage II Citrullus lanatus cv. Charlee (watermelon) plant tissue cultures to further enhance productivity. Mounting the cutter in an inverted position over the receiving vessel eliminated time required for filling. This cut-and-dump technique became 4.8 times more productive for the total transfer process than the conventional scalpel and forceps technique when both time and yield of cut segments with visible buds were considered. A concept for growing fewer, larger tissue clusters per vessel in mini-trays with orienting cells and …
