Democratization and Women's Empowerment: The Effects of Electoral Systems, Participation and Repetition in Africa.

This article investigates three hypotheses suggested in the literature on women's political empowerment, operationalized here as increased legislative representation. These hypotheses are that (1) electoral systems manipulate women's political empowerment; (2) increased popular participation empowers women in particular; and (3) accumulated experience gained over several electoral cycles facilitat

The potential of polymeric cryogels in bioseparation

This is a review discussing the production and properties of cryogels (from the Greek κριoσ (kryos) meaning frost or ice), immobilization of ligands in cryogels and the application of affinity cryogels in bioseparation. Cryotropic gel formation proceeds in a non-frozen liquid microphase existing in the macroscopically frozen sample. Due to the cryoconcentration of gel precursors in the non-frozen

Two major classes in the M protein family in group A streptococci

The M protein family of molecules in the group A streptococcus comprises a number of cell surface proteins that interact with the immune system of the host. One of the proteins in this family is the IgA receptor Arp4, which has C repeats similar to those that characterize the known M proteins. The streptococcal strain expressing Arp4 also expresses a second immunoglobulin-binding protein, Mrp4, wh

Risk of collapse in the eastern Baltic cod fishery

The eastern Baltic cod fishery, as many fisheries worldwide, is experiencing a major crisis. The combination of current environmental conditions, fishing mortality rates, and stock size indicates that this fishery is not sustainable. In order to rebuild the population and sustain the fishery in the future, it is essential to define a biologically appropriate exploitation level. In this paper, we t

Photochemical reactivity of aquatic macrophyte leachates: abiotic transformations and bacterial response

We evaluated the influence of UV radiation exposure time on abiotic transformations of leachates from 2 aquatic macrophytes: Phragmites australis and Hydrocaris morsus-ranae. In addition, we studied the influence of phototransformations of DOM on bacterial growth. Sterile filtered leachates were exposed to UV radiation for 5, 10, 24, 48, 72 and 120 h or kept in the dark. Dissolved inorganic carbon

ACTH reduces the rise in ApoB-48 levels after fat intake.

It has been repeatedly demonstrated that ACTH administration lowers plasma lipid concentrations in man. The present study was designed to test the hypothesis, based on observations of decreased apolipoprotein B (ApoB) synthesis and secretion in vitro, that ACTH administration inhibits the postprandial output of ApoB in man. Therefore, we studied the response to a fat-rich meal supplemented with Vi

Sensed presence and mystical experiences are predicted by suggestibility, not by the application of transcranial weak complex magnetic fields

Transcranial magnetic stimulation (TMS) with weak (micro Tesla) complex waveform fields have been claimed to evoke the sensed presence of a sentient being in up to 80% in the general population. These findings have had a questionable neurophysiological foundation as the fields are approximately six orders of magnitude weaker than ordinary TMS fields. Also, no independent replication has been repor

Effects of litter addition and warming on soil carbon, nutrient pools and microbial communities in a subarctic heath ecosystem

Climatic warming leads to the expansion of deciduous shrubs and trees in the Arctic. This leads to higher leaf litter inputs, which together with warming may alter the rate of carbon and nutrient cycling in the arctic ecosystems. We assessed effects of factorial warming and additional litter on the soil ecosystem of a subarctic heath in a 7-year-long field experiment. Fine root biomass, dissolved

Oxidized LDL antibodies in treatment and risk assessment of atherosclerosis and associated cardiovascular disease.

Immune responses against oxidized forms of LDL play a critical role in activation and regulation of the inflammatory process that characterizes all stages of atherosclerosis. In humans oxidized LDL is targeted by both IgM and IgG autoantibodies. Immunization of hypercholesterolemic animals with oxidized LDL has been shown to inhibit atherosclerosis demonstrating that at least some of these immune

The instability of planetary systems in binaries: how the Kozai mechanism leads to strong planet-planet interactions

In this Letter we consider the evolution of a planetary system around a star inside a wide binary. We simulate numerically the evolution of the planetary orbits for both coplanar and highly inclined systems. We find that the Kozai mechanism operates in the latter case. This produces a highly eccentric outer planet the orbit of which crosses those of some of the inner planets. Strong planet-planet

Effects of waterfowl, large fish and periphyton on the spring growth of Potamogeton pectinatus L. in Lake Mogan, Turkey

It has been argued that waterfowl and fish may threaten growth of submerged macrophytes, especially in spring during the early growth phase when plant biomass is low. A small reduction of biomass at that time might delay growth or decrease subsequent productivity. We investigated the impact of waterfowl and large fish on the spring growth of fennel pondweed (Potamogeton pectinatus L.) by employing

Non-contact surface wave scanning of pavements using a rolling microphone array

We present experiments with a rolling multichannel microphone array where measurements can be taken continuously while moving. Leaky air-coupled surface waves are measured with ordinary non-directional audio microphones. Results show that microphones can be successfully used to produce a realistic phase velocity spectrum even while moving along the surface. The paper presents some theoretical back

Intrathecal cyclosporin prolongs survival of late-stage ALS mice

Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disease characterized by upper and lower motor neuron death with ascending paralysis leading to death. In a transgenic mouse model of ALS (SOD1-G93A) weakness appears at 3 months of age, and because of progressive paralysis leads to death by 5 months. Cyclosporin A (CsA) is well known, for its extracerebral effect, as an immunosuppressant

Green tea powder and Lactobacillus plantarum affect gut microbiota, lipid metabolism and inflammation in high-fat fed C57BL/6J mice

Background: Type 2 diabetes is associated with obesity, ectopic lipid accumulation and low-grade inflammation. A dysfunctional gut microbiota has been suggested to participate in the pathogenesis of the disease. Green tea is rich in polyphenols and has previously been shown to exert beneficial metabolic effects. Lactobacillus plantarum has the ability to metabolize phenolic acids. The health promo

Monitoring Assisted Robust Routing in Wireless Mesh Networks

In this paper, we present a monitoring assisted robust routing scheme for wireless mesh networks which exploits the broadcast nature of wireless transmissions at special routers with added monitoring functionalities. These routers passively listen to the transmissions in their neighborhood and compare the routing behavior against the routing state collectively maintained by them. If any inconsiste
