Disparities In The Utilization Of Nambia's Grassland: A Need For Adjustments In The Beef Industry, Helmke Sartorius Von Bach, Johan Van Zyl

IGC Proceedings (1977-2023)

Extensive beef production, Namibia's life-line in agriculture, depends entirely on natural pastures. Socioeconomic and environmental disparities, namely (a) the· traditional smallholder communal sector versus the commercial sector and (b) areas in the vicinity versus distant from centralised abattoirs, are analysed by' using econometric analysis of time-series data on the regional influence of prices and· access to markets on beef numbers. This is particulary relevant because Namibia is in a process of structural adjustment, and in view of the beef sector's importance in the Namibian economy. The results accentuate the role of access to markets and productive opportunities for beef production …

Cadmium In Soil, Pasture And Grazing Ruminants, J Lee, N D. Grace, A D. Mackay, M J. Hedley, J R. Rouce

IGC Proceedings (1977-2023)

Cadmium, present in New Zealand hill country pastures rrom Cd­amended phosphatic fertiliser use, is assimilated by grazing ruminants. Concentrations of Cd in plasma from sheep grazing pastures containing low (0.1-0.2µglg dry weight) or high (0.8-1.4 µgig dry weight) levels of Cd were 0.15±0.04 nglg and 0,35:1:0.15 ng/g, respectively (P<0.08). Cadmium in pasture was highly correlated (P<0,001) with soil O.IM HCl-extractable Cd (log10 Soiled= -0.98+0.26 Plantcd).

Nitrogen Dynamics In Three Contrasting Grassland Systems: Implications For Pasture Productivity And The Potential For Environmental Pollution, B E. Ruz-Jerez, R E. White, P Roger Ball

IGC Proceedings (1977-2023)

Nitrogen (N) dynamics were compared in 3 contrasting grassland systems (2 legume-based and I receiving fertiliser N) in a cool temperate region of New Zealand. The study was concentrated on the various N transfers that occurred during and after grazing. Critical periods for N loss by different processes have been identified, allowing a more comprehensive understanding of the role of N in the productivity of different types of pasture, and the potential for environmental pollution, Calculation of N inputs and outputs for the three pastures indicated that the two legume-based systems were more or less in balance, but in the …

Reduction Of Nutrient Losses For Dairy Farms, With Emphasis On Nitrogen, W Luten, D J. Den Boer

IGC Proceedings (1977-2023)

Recently the Dutch government presented several policy papers in which standards are given for maximum allowed emissions to air, groundwater and surface water. Depending on the farm situation an optimum combination of measures in relation to housing, slurry storage, slurry and fertiliser application, and composition of the ration can be taken. In general a better use of nutrients from animal manure by applying slurry with low emission techniques in the growing season and a reduction of the stocking rate by a higher milk production per cow are the most effective and cheapest measures to reach these targets. There is a …

Pastoral Systems Of Central Himalaya: How Long Will They Survive?, K S. Rao, K G. Saxena

IGC Proceedings (1977-2023)

Pastoral systems of Central Himalaya are very old and until recent time were in balance with environment, Recent changes in socio­political setup have drastically altered the status of these systems. The change of political power in trans-Himalayan Tibetean plateau has resulted in closure of international boarders, thus taking away the mercantile aspects of pastoralists and reducing pastoral area. Increased human disturbances on fragile Himalayan marginal lands and excessive onslaught on forests for fuel and fodder by the sedentary population has resulted in degradation and non-productive grasslands which do not help pastoralists sustain existing systems. Changes in relations between migratory pastoralists …

Sustainable Direction For Resource Management An Assessment Of The Regional Council Role, Allan Lohrey

IGC Proceedings (1977-2023)

The 1980s has seen an increased world awareness of the concept of sustainability. In 1991 New Zealand enacted the Resource Management Act (RMA) which reflected society's concern for a need to consider future generations when making decisions relating to the use of natural resources. Regional councils have been allocated the role within the Act to promote sustainable management at the regional level. The short term challenge to regional councils is to manage resources in manner which strikes a pragmatic balance between the ongoing needs of society and the need to provide resources for future generations. Regional councils will know they …

Locating The Ilokano Baglan In The Gender And Sexuality Continuum, Aurelio Solver Agcaoili

Budhi: A Journal of Ideas and Culture

The article is an attempt to recover the baglan tradition of ritual healing among the Ilokano people. Currently, only pejorative comments exist about this baglan tradition whose practices represent the continuum of sex, sexuality, and gender among these groups of people in the Northern Philippines. The argument presented leads to a critique of knowledge formation in colonial Ilocos and unmasks the problem of reproduced versions of the truth about the baglan and their role in the definition of the healthy human being and the healthy community. The ungendered baglan, is, in fact, the person that is all-gender, all-sex, and all-sexuality, …

Breakthrough Conductivity Enhancement In Deep Eutectic Solvents Via Grotthuss-Type Proton Transport, Desiree Mae Prado, Clemens Burda, Anthony Jahng, Kayla Poling

Faculty Scholarship

There is an increasing demand for the development of ion-conducting electrolytes for energy storage systems. Much attention is directed toward deep eutectic solvents as potential candidates. In the search for highly conductive systems, the possibility of designing deep eutectic solvents with Grotthuss-type proton transport is widely overlooked. Herein, ethaline, a mixture of choline chloride and ethylene glycol is used in a 1:2 molar ratio, to induce a significant conductivity increase with the addition of water and sulfuric acid (H₂SO₄). The achieved breakthrough conductivity is analyzed experimentally and simulated with ab initio molecular dynamics (AIMD). At sufficient water content, an H-bonding …

A Basic Qualitative Study Of African American Covid-19 Survivors’ Experiences, Beliefs, And Critical Health Literacy, Lauren Erika Myers

Walden Dissertations and Doctoral Studies

African Americans make up 13.4% of the U.S. population but accounted for 18.2% of those infected and 20.9% of deaths, reflecting significantly higher rates of illness and mortality from the COVID-19 pandemic than their non-African American counterparts. This disparity makes the effects of the COVID-19 pandemic as much a social concern as it is a health issue. The purpose of this study was to explore critical health literacy among African American COVID-19 survivors within the conceptual framework of the health belief model (HBM) in conjunction with critical health literacy theory. The overall research design is basic qualitative design using a …
