Leaching Mechanism Of Semiconducting Minerals, Fathi Habashi

Fathi Habashi

The mechanism of leaching of semiconducting minerals such as PbS, ZnS, UO2, etc., has been the subject of intensive speculation by hydrometallurgists in the early 1950s. The electrochemical mechanism proposed in 1970 by the author in volume 2 of his Principles of Extractive Metallurgy avoids the assumption of forming intermediate complexes that cannot be isolated or identified.

Institutional Structure And Decision Making In Sudan, Professor Issam A.W. Mohamed

Professor Issam A.W. Mohamed

The study here presented reviews the institutional structure of the Sudanese government. Truly, though it is stigmatized as totalitarian, the structure is phenotypically perfect. Ministry of Ministries council is supposed to cater for analyzing data concerning ministries performance, drawing strategic planning, executing them through ministries and conduct the follow-ups. Department of decision-making was created and packages for data collection and analyses were improvised. However, all these structures seem skeletal as the final decisions structurally seem to be lost between the Presidency Institution and the executive institutions. An introduced flowing chart indicates that the cycle of all decisions end up at …

The International Society And The Sudanese National Disintegration, Professor Issam A.W. Mohamed

Professor Issam A.W. Mohamed

The political crisis of Sudan is amplified everyday with the expansion of civil conflict from Darfur to Southern Kordofan state. The inevitable secession of Southern Sudan is threatened by the chronic crisis of Abyei pocket between the north and the south that saw open war between the two opponents; the Sudanese army and Popular Liberation of Sudan. Nevertheless, the Attorney General of the International Criminal Court, Ocambo vocalizes more concerns of humanitarian sufferings and war crimes that he claims to be continuing despite of peaceful negotiations. Such situation seems irrational with the de facto state of war that currently prevails …

The Impact Of Tribal Structure On The Economic Parameters And Conflicts Between North And South Sudan, Professor Issam A.W. Mohamed

Professor Issam A.W. Mohamed

The crisis of Greater Darfur Region of Sudan extends to other regions as the South Sudan prepares for secession next July 2011. In the past eight years Sudan's crisis in Darfur was amplified by global news media all over the world. Civil conflict erupted, developed into armed rebellions and open uncontrolled war that enveloped the whole region. The current inflamed undecided and unmarked future borders between the south and north are also facing growing tensions. In this current paper we present some information on what we see as the seeds of conflicts with complicated tribal structures in both sides and …

Growth And Species Interactions Of Eucalyptus Pellita In A Mixed And Monoculture Plantation In The Humid Tropics Of North Queensland, Mila Bristow, Jerome K. Vanclay, Lyndon O. Brooks, Mark Hunt

Dr Lyndon O Brooks

This study investigated whether mixed-species designs can increase the growth of a tropical eucalypt when compared to monocultures. Monocultures of Eucalyptus pellita (E) and Acacia peregrina (A) and mixtures in various proportions (75E:25A, 50E:50A, 25E:75A) were planted in a replacement series design on the Atherton Tablelands of north Queensland, Australia. High mortality in the establishment phase due to repeated damage by tropical cyclones altered the trial design. Effects of experimental designs on tree growth were estimated using a linear mixed effects model with restricted maximum likelihood analysis (REML). Volume growth of individual eucalypt trees were positively affected by the presence …

Fend For Sudan Unity, Professor Issam A.W. Mohamed

Professor Issam A.W. Mohamed

Sudan is unified as a country by many bonds that are also reasons for it disintegration. From the year 2005 where Nivasha Comprehensive Peace Agreement between the North and South parts, to 2011 the efforts of dividing the country were evident. From 2005, many analysts, tried to warn of the coming consequences of the Southern part secession. There were calls for improvements of the current regime's totalitarianism, open the doors for democracy, sharing people in power and decision making and amending human standards and freedom. However, all calls fell on deaf ears. The Darfur crisis accelerated and the regime clutch …

Economic Crisis And External Trade In Sudan, Professor Issam A.W. Mohamed

Professor Issam A.W. Mohamed

Nowadays, Sudan suffers severe financial crisis with the eminent demise of 75% of its oil revenues that represented over 90% of its foreign currency after the secession of its Southern part after a constitutional referendum. The compensatory revenues generating economic sectors are not able in the short, medium or runs to function due to the lack/diminished infrastructures. Hard currency exchange rates have soured against the domestic one and inflation sky-rocketed with severe recession grasping the economic cycle in the country which assess logic assumptions of stagflation. Reforming Sudan's foreign trade sector is essential though it will not replace oil revenues …

European Policies On Land Compensation And Support For Displaced Rural Workers: Relevance To China, Mel Cousins, Zhihui Wu, Jean-Phillipe Lhernould, Malgosia Rusewicz, Simon Roberts

Mel Cousins

This report examines the position of farmers who have lost their land (or displaced rural workers) in China. It studies policies adopted in three EU countries (France, Poland and the UK) (i) to provide compensation for land which has been compulsorily purchased; and (ii) to provide social policy support to disaplaced rural workers. It draws out the possible implications of these EU experiences for China

Spring-Fed Stream Benthic Macroinvertebrate Communities As Early Biological Indicators Of Groundwater Tipping Points., Rosemary A. Burk, Jan Kallberg, James H. Kennedy

Rosemary A. Burk

In 2007, a 20-county area encompassing the Dallas-Fort Worth Metroplex was designated by the State as a Priority Groundwater Management Area (PGMA) in need of implementing strategies for groundwater conservation. The newly created PGMA’s population is expected to increase from 5.5 million in 2000 to 9.5 million by 2030 with projected water needs rising from 1,677 million m3 in 2000 to 3,034 million m3 by 2030 according to a study by Texas Commission on Environmental Quality (TCEQ). The Trinity Aquifer supplied 73% of the area’s groundwater in 2000, with the aquifer outcrop zone being highly susceptible to anthropogenic sources of …

Analysis Of The Regulatory Effects Of California Specialty Crops: An Examination Of Various Issues Impacting Selected Forest Products, Tree Fruit, Nut, And Vegetable Crop Industries, Sean P. Hurley, Richard Thompson, Christopher Dicus, Lori Berger, Jay E. Noel

Christopher Dicus

In a research report for the California Institute for the Study of Specialty Crops, Hurley provided a broad overview of the web of regulatory bodies affecting California agricultural producers. He found that California specialty crop producers must comply with multiple regulations from multiple local, state, and federal agencies. Locally, producers must comply with county land use regulations developed by the county, as well as, regulations established by the County Agricultural Commissioner. At the state level, producers must follow the regulations established by California Environmental Protection Agency (CALEPA), the Department of Pesticide Regulation (DPR), and the California Department of Food and …

Consumer Perceptions Of Three Food Safety Interventions Related To Meat Processing, Christiane Schroeter, Karen P. Penner, John A. Fox

Christiane Schroeter

A focus group study with 37 residents of Manhattan, Kansas, was conducted to examine consumers' risk perceptions of foodborne illnesses from eating beef. The four focus-group sessions were designed to determine (1) relative preferences for alternative combinations of public food safety measures (Hazard Analysis Critical Control Points [HACCP], carcass pasteurization, irradiation) and private protection (home preparation of rare, medium, and well-done hamburgers); (2) how who is at risk (children vs. adults) influences preferences; (3) whether consumers would pay a premium for increased product safety arising from the adoption of three different innovations in processing plants; and (4) how to improve …

Relating Diet, Demographics And Lifestyle To Increasing U.S. Obesity Rates, Christiane Schroeter

Christiane Schroeter

Changes in the American lifestyle are putting more individuals at risk due to the declining quality of their diets. In the last 20 years, the readily available high-fat foods (e.g., "fast foods") combined with the decreased caloric requirements due to lower physical activity levels is assumed to be the major factor in the sharp rise in the prevalence of obesity. The typical away-from-home meal is less healthy than food at home, since it tends to contain more total fat and saturated fat, less calcium, fiber, and iron, and fewer servings of fruits and vegetables. Furthermore, due to the super-sizing trend …

Determining The Impact Of Food Price And Income Changes On Body Weight, Christiane Schroeter, Jayson Lusk, Wallace Tyner

Christiane Schroeter

We develop a theoretical model to identify conditions under which price and income changes are most likely to change weight. Although it is intuitive that raising the price of high-calorie food will decrease consumption of such goods; it is not clear that such an outcome will actually reduce weight. Our empirical analysis demonstrates a case where a tax on food away from home, a food intake category blamed for much of the rise in obesity, could lead to an increase in body weight; a finding which emphasizes the need to employ economic modeling when developing public policy to reduce obesity.

Fruit And Vegetable Consumption Among College Students In Arkansas And Florida: Food And Culture Vs. Health Knowledge, Christiane Schroeter, Lisa House, Argelia Lorence

Christiane Schroeter

This study determines the impact of demographics, dietary and health knowledge, and food culture on fruit and vegetable consumption of college students in Arkansas and Florida. Our empirical analysis demonstrates that food culture significantly impacts consumption of fruits and vegetables; a finding which emphasizes the need to target cultural aspects when developing effective and efficient management of agribusiness firms. Understanding the antecedents to consumption for products like fruits and vegetables is important to agribusiness industry, policy makers and organizations interested in evaluating the effectiveness of health education in promoting college students’ health and decreasing the trends to obesity.

The Impact Of Health Information And Women In The Work Force On Aggregate Meat Demand, Christiane Schroeter, Ken Foster

Christiane Schroeter

Over the past few decades, U.S. meat consumption patterns have changed. Changes in food consumption patterns can be the result of changing demographic characteristics, changing lifestyles, increasing health awareness, and nutritional concerns. Prior research suggests that these factors have significant influence on the demand for meat (Capps and Schmitz; Kinnucan, Hsia, and Jackson). The recent interest in low carbohydrate diets and the association with increased red meat consumption is an anecdotal example of this phenomenon.

The Janjaweed, The Armed Movements And The Political Disintegration Of Sudan, Issam A.W. Mohamed Professor

Professor Issam A.W. Mohamed

The present paper is part of unpublished book divided into three interrelated manuscripts that analyze the collapse of the Sudan. The current paper concludes that the rebellion by certain in Darfur region has triggered a further a counteraction by other tribes of Arab descendants. The counter-actors were recruited by an unprecedented tyrannical regime to submit the rebels but succeeded only in genocide and the turning over the regime and started their own rebellion. That resulted in an intricate situation carrying all symptoms of chaos. Truly, the regime maintained its existence but with continuously deteriorating life condition in Darfur region. The …

Estimating The Impacts Of Differing Price-Risk Management Strategies On The Net Income Of Salinas Valley Lettuce Producers: A Stochastic Simulation Approach, Roland Fumasi, Wayne H. Howard, Jay E. Noel

Jay E. Noel

While government safety-net programs are used to mitigate the price risk for commodity producers, limited programs exist for specialty crop producers. Specialty crop producers utilize forward contracts to reduce downside price risk. In order to estimate the method of price-risk management, if any, that is preferable to selling at market determined prices, a stochastic simulation model was constructed. The completed simulation model was used to estimate probability distributions for Salinas Valley net income under different pricing scenarios. Probabilities of reaching various net income thresholds were compared. Results indicate that Salinas Valley lettuce producers should maximize profitability by using forward contracts.

Devolution Of Federal Agricultural Policy: The Case Of Specialty Crop Block Grants, Jay E. Noel, David Schweikhardt

Jay E. Noel

There is a lengthy history of devolution of federal policy and programs to the states through the use of grants-in-aid in general and block grants in particular. In the area of agricultural policy, for example, programs for agricultural research and extension have, since their origin, been jointly funded by a system of grants from the federal government to the states. In recent years, the possible consequence of a major devolution of farm policy and programs from the federal government to the states has received much attention.
