This study was carried out at 3 pig farms in Van Giang district of Hung Yen province in winter and summer. Its aims to evaluate the influences of different seasons on the air quality inside the pigsty. The air quality was determined by some criterias: temperature, humidity, air speed, the concentration of CO2, H2S and NH3 around the pig house. Results of this research provide farmers with basic knowledge not only about designing and building pig cages but also rasing pigs suitably with different seasons. The results showed that, in both summer and winter, the value of temperature and humidity in pigsites was under permissible limits. Meanwhile, the concentration of CO2, H2S and NH3 were higher than permitted values. In summer, the the concentration of CO2, H2S, NH3 was higher than standard values (3.6 - 5.0; 2 - 26; 1.5 - 8 times respectively). In winter, the amount of these gases were higher the standard values (4.6 - 12.5; 2 - 26; 8.5 - 13.5 times respectively). In winter, the air quality was not good as that in summer with higher level poisonous gases (CO2: 1.2 to 1.5; H2S: 1.1 to 10; NH3: 1.1 to 6.3 times as compared with those in summer). Seasonal factor affected remarkably on indoor climate of pig house. [less ▲]

In this paper, I examine the experience of listening to one's environment from an ethnographic standpoint. After a brief review of the conceptualizations of everyday listening in the literature, I focus on the difficulties of its observation. I then propose to take noise annoyance as a mean to investigate everyday listening. I show that the heuristic power of noise annoyance comes from the reflexivity towards one's own listening that it fosters. [less ▲]

AIM OF THE STUDY: The in vitro antiplasmodial activity and cytotoxicity of methanolic and dichloromethane extracts from five Congolese plants were evaluated. The plants were selected following an ethnobotanical survey conducted in D.R. Congo and focusing on plants used traditionally to treat malaria. The in vivo antimalarial activity of aqueous and methanolic extracts active in vitro was also determined in mice infected by Plasmodium berghei berghei. MATERIALS AND METHODS: The growth inhibition of Plasmodium falciparum strains was evaluated using the measurement of lactate dehydrogenase activity. The extracts (aqueous, CH(3)OH, EtOH and CH(2)Cl(2)) were prepared by maceration and tested in vitro against the 3D7 (chloroquine sensitive) and W2 (chloroquine resistant) strains of Plasmodium falciparum and against the human normal fetal lung fibroblasts WI-38 to determine the selectivity index. Some extracts were also used at the dose of 300mg/kg to evaluate their activity in mice infected since 4 days by Plasmodium berghei. RESULTS: Two plants presented a very high activity (IC(50)<3mug/ml). These plants were Strychnos icaja roots bark (MeOH and CH(2)Cl(2)) and Physalis angulata leaves (MeOH and CH(2)Cl(2)). One plant (Anisopappus chinensis whole plant, MeOH and CH(2)Cl(2)) presented a high activity (IC50<15mug/ml). The extracts of Anisopappus chinensis and Physalis angulata showed also a good inhibition of parasitemia in vivo. Flavonoids, phenolic acids and terpenes were identified in these plants by a general phytochemical screening method. CONCLUSION: Three plants showed a very interesting antiplasmodial activity (Anisopappus chinensis, Physalis angulata and Strychnos icaja) and one of them showed a good selectivity index (>10, Anisopappus chinensis). Anisopappus chinensis and Physalis angulata were also active in vivo. [less ▲]

This contribution intends to give a preliminary view of the diet of the Cormorant on the lake Kivu. Fifty pellets were collected from August to October 2004 in a colony situated in Bukavu and analysed. A reference collection of fish skull bones was also prepared and correlations between the length of some characteristic bones and the total length of the fish were computed, allowing the assessment of the length of each prey identified in the pellets. The cormorants eat mainly Haplochromis species (either in relative abundance or occurrences) but the biomass intake is dominated by the genera Tilapia and Oreochromis (together: 65 %). The importance of catfish (Clarias sp.) or barbels (Barbus sp.) is very small (< 4%, whatever the expression of the results). The sardine Limnothrissa miodon appears in 1 out of 5 pellets but its contribution in terms of biomass is negligible. Comparing the diet with the available resources, it appears that the cormorant is an opportunistic predator, taking almost all the available taxa (except Raiamas moorii) without selecting a particular one, except the big cichlids (genus Tilapia and Oreochromis). However, more than 90% of its preys are small fish measuring less than 10 cm. [less ▲]

Traditionally regarded as a mere critical inversion of utopia, dystopia will be characterized here as an instance of a more general critical posture, through the concepts of ‘future perfect’ and ‘counterfactual precedent’. The future perfect belongs to, but differs from the logics of alert in its temporal modalities and use of fiction: the dystopian future is described as having already happened in the actuality of the narrative present, in a paradoxical gesture which aims to conjure up the threat in the recipient’s representational space only to thwart it. The cases examined are taken from the issue of new technologies of surveillance and social control, which challenged stakeholders to update their critical reference points and anticipation skills over the last twenty years. An analysis in terms of the future perfect enables us to understand the swing of configurations: Big Brother is now downgraded as a ‘counterfactual precedent’ compared to the new threats posed by ‘societies of control’. In addition, the similar way these fictional patterns and figures operate points to a cognitive (the articulation between the real and the possible worlds accessed by anticipation) as well as a pragmatic dimension (empowering the political community to envision a new future). By the end of the analysis, fiction appears as both a mode of knowledge and a handle on the world. [less ▲]

The study was conducted in the “Mare aux Hippopotames” Biosphere Reserve of Burkina Faso and aimed at assessing the number, age structures and seasonal mobility of Hippopotamus amphibius. Methodology used was based on three consecutive-year (2006-2008) monitoring and ground inventory inside and outside the reserve. The results of the inventories have led to the identification of 41 hippopotamus in 2008 versus 35 in 2006 which are divided into 3 distinct herds. The structure in age group of that population was composed of 32 were adults, 5 sub-adults and 4 juveniles. Location of places where they take a rest varies with the level of the water in the pond. The inventory has identified eight sites on each side of the pond as used by hippos to harvest food. In addition, exploration of the reserve has identified four temporary ponds located near the water meadows used by hippos during the rainy season. These areas were surrounded by agricultural fields that were often raided by these mammals for food. It is urgent to zone agricultural activity in the area and to grant a special conservation status to the four additional ponds to minimize conflicts between humans and hippopotamus. Finally, local participation in conservation activities is probably greatly responsible for an increase in the size of the hippo population. [less ▲]

The long pentraxin 3 (PTX3) plays an important role in host defence and its over-expression may contribute to airway injury. The aim of the present study was therefore to characterize in more detail PTX3 and its expression in the horses airway. Six healthy horses and six horses affected by recurrent airway obstruction (R.A.O.) were submitted to a dusty environment challenge. PTX3 DNA and cDNA were cloned and sequenced. PTX3 expression was evaluated by RT-qPCR, western blotting and immuno-histochemistry in bronchoalveolar lavage fluid (BALF) cells, BALF supernatant and bronchial epithelial cells. An alternative splicing of the second exon of PTX3 occurred, resulting in two forms of the protein: spliced (32 kDa) and full length (42 kDa). PTX3 was detected in BALF macrophages, neutrophils and bronchial epithelial cells. It was over-expressed in the BALF supernatant from R.A.O.-affected horses in crisis. However, dust was unable to induce PTX3 in BALF cells ex vivo, indicating that dust is an indirect inducer of PTX3. Dust exposure in-vivo induced PTX3 in BALF macrophages but there was no significant difference between healthy and R.A.O.-affected horses. Conversely, PTX3 was over-expressed in the bronchial epithelial cells from R.A.O-affected horses in crisis. These data indicate a differential regulatory mechanism in inflammatory and bronchial epithelial cells and offer therapeutically interesting perspectives. [less ▲]

OBJECTIVES: To analyse the first four rounds of country applications to the GAVI Alliance Health Systems Strengthening (GAVI-HSS) funding window; to provide valuable insight into how countries prioritize, articulate and propose solutions for health system constraints through the GAVI-HSS application process and to examine the extent to which this process embodies alignment and harmonization, Principles of the Paris Declaration. METHODS: The study applied multiple criteria to analyse 48 funding applications from 40 countries, submitted in the first four rounds, focusing on the country analysis of health systems constraints, coordination mechanisms, alignment with national and sector planning processes, inclusiveness of the planning processes and stakeholder engagement. RESULTS: The applications showed diversity in the health systems constraints identified and the activities proposed. Requirements of GAVI for sector oversight and coordination, and the management of the application process through the Ministry of Health's Planning Department, resulted in strong alignment with government policy and planning processes and good levels of stakeholder inclusion and local technical support (TS). CONCLUSION: Health Systems Strengthening initiatives for global health partnerships (GHPs) can provide a link between the programmatic and the systemic, influencing policy alignment and harmonization of processes. The applications strengthened in-country coordination and planning, with countries using existing health sector assessments to identify system constraints, and to propose. Analyses also produced evidence of broad stakeholder inclusiveness, a good degree of proposal alignment with national health plans and policy documents, and engagement of a largely domestic TS network. While the effectiveness of the proposed interventions cannot be determined from this data, the findings provide support for the GAVI-HSS initiative as implementation continues and evaluation begins.
