- Apolipoprotein E-epsilon 4 is the main known genetic risk factor for Alzheimer’s disease. Functional abnormalities in the parietal cortex have been reported for Alzheimer’s disease patients and also for those at risk. Hence, a critical question is whether measurements of parietal cortex integrity may predict negative outcome among at- risk persons. We studied nondemented apolipo-protein E-epsilon 4 carriers and found a significant relationship between parietal blood-oxygen-level-dependent functional magnetic resonance imaging response during a word categorization task and subsequent episodic memory performance. Thus, the results show that parietal cortex alterations predict memory decline in nondemented apolipoprotein E-epsilon 4 carriers, and hence likely progression to Alzheimer’s disease.

- Jordan has seen a large increase in inhabitants over the past five decades as a result of a high population growth rate and forced migrations. Economic and cultural development has improved the standard of living and changed consumer habits, resulting in an increase in the volume of municipal solid waste (MSW) over time. The rate of production of MSW has been estimated at about 1,964,284 ton annually with an average generation rate of 0.95 kg/ cap/day in urban and 0.85 kg/cap/day in rural areas (SWEEP, 2010) and is expected to reach 2.5 million ton by 2015. The major fraction of MSW composition is organic (Fig. 1), which implies a high moisture content value, as expected in a developing country where food is the major component of the solid waste stream (Abu Qdais, 2007). About 86% of the MSW is decomposable and recyclable, while the remainder is inert matter. The solid waste volume is still increasing at high rates due to the rapid population increase as well as the change in living standards and consumption patterns.

Tidskriftsartikel (populärvet., debatt m.m.)abstract
- Municipal solid waste is one of the major environmental problems in Jordan. The World Bank visibility study (2004) showed that the rate of production of solid waste in Jordan was estimated annually of about 1.46 million ton, and is expected to reach 2.5 million ton by the year 2015 with a generation of 0.9/kg/capita/day. This solid waste volume is still increasing at high rates due to the rapid increase of populations and change in living standards and the consumption patterns. The majorities of landfills in Jordan are practicing open dumping and thus cause various environmental problems such as health hazards, surface water and ground water contamination, odors, etc. Sanitary landfills offer a viable option for the Common Service Councils (CSCs) which are responsible for operation and management of disposal sites in the country, to deal with the environmental hazards caused by open dumps practice within its financial constraints. If sanitary landfills are conducted properly, the negative environmental impacts can be kept to a minimum level. This paper will discuss the environmental, economic and social opportunities of moving open dumps toward sanitary landfills such a transfer is necessary and it could play important roles in tackling the pressing solid waste problems and a forward step for an approach for integrated solid waste management in the country.

Municipal Landfilling Practice and Its Impact on the Water Resources - Jordan

Tidskriftsartikel (populärvet., debatt m.m.)abstract
- Jordan is considered one of the most water-stressed countries in the world, with less than 150 cubic meters freshwater available per capita annually. Groundwater resources are clearly vital for Jordan´s population and economic wellbeing. It´s quality and amount has therefore to be managed in a sustainable way avoiding possible contaminations. Unfortunately the groundwater quality is threatened by several factors including unsafe landfilling. Jordan has been facing a unique situation in solid waste management due to sudden population and the change in living standards. Serious environmental problems are connected to this, which could threaten human, surface water and ground water. With the current regulation and attention focused in many environmental aspects in the country, the risk of water resources contamination is not completely recognized. The aim of this study is to provide an overview of environmental problems associated to the mismanagement of solid waste and the possible threats for human and water resources.

Tidskriftsartikel (populärvet., debatt m.m.)abstract
- Solid waste became one of the major environmental problems in Jordan, which has been aggravated over the past 15 years by the sharp increase in the volume of waste generated as well as qualitative changes in its composition. The challenges face solid waste management (SWM) in Jordan are numerous. Financial constraints, shortage of proper equipment and limited availability of trained and skilled manpower together with massive and sudden population increases due to several waves of forced migration. In this work we discussed these challenges; the main problems which stand against developing this sector to sustainable levels in the coming future are identified. Suggestions and recommendations that should be taken in consideration for developing the sector are also presented

The Role of Informal Sector in Waste Management, A Case Study; Tafila-Jordan

Tidskriftsartikel (populärvet., debatt m.m.)abstract
- Scavengers play a major role in the waste management process in developing countries. This study analyzed the informal recycling activities carried out by scavenger in the Tafila region of Jordan. The results show that scavengers have an important role in the informal solid waste management (SWM) especially in term of waste reduction, minimization and material recovery. Significant values from the scavenged material make the scavenging somewhat a profitable business for poor people and could track more in the future. Socially scavenging tends to be acceptable in the community, especially with the increasing of the poverty and employments rates and became more acceptable in rural areas as it is already in urban areas. Despite the low level of education, the awareness for the negative health effect from working with waste was very high. The organizing of the scavenger work is suggested, since it would improve their working environment, income and living conditions. Therefore it should increase their contribution significantly to resource recovery.

- In a study of the neutralization capacity and limestone content the artificial recharge area of the Sydvatten waterworks Vombverket in Vomb, Skåne, five samples from different locations in the area was collected, sieved and acidified with hydrochloric acid. The neutralization capacity measured as calcium carbonate content was found to vary in the different sandy soil samples but was generally high (about 2–14 % by weight). The total mass of calcium carbonate in the infiltration area was determined taking into account the volume and density, i.e. possible porosity of the soil. There is at least equal to 4.3 million tons of calcium carbonate present in the infiltration area. This corresponds to a neutralization capacity of 88 x 109 moles in the study area. The annual limestone dissolution in the area is about 750 tons. The limestone content in the area is generally high and has a good ability to buffer also more acidic water than water from Vombsjön. At present limestone consumption, the neutralization capacity lasts for at least 5700 years.
