Composition of Rambutan Seeds

The seeds of three rambutan clones (R4, R 7 and R169) were analysed. Proximate analysis of the seeds showed that they contained 11.9-14.1% protein, 37.1-38.9% crude fat (peroleum ether extract), 2.8-6.6% crude fibre and 2.6-2.9% ash on a dry weight basis. The seeds contained 34.1-34.6% moisture. The amino acid profile of the seed protein showed that the protein was of good quality. The major fatty acids in rambutan seed fat were C16:0 (4.36-4.86%); C18:0 (5.93-7.49%); C18:1 (37.91-40.15%); C20:0 (36.14-36.77%) and C20:1 (6.92-7.27%)

Impact of secondary hard substrate on the distribution and abundance of Aurelia aurita in the western Baltic Sea

Highlights: • Impacts of wind farms on the occurrence of the moon jelly Aureliaaurita. • Artificial hard substrate has the potential to increase the abundance of A.aurita. • In the given example the abundance of A. aurita increases about 20%. • Distribution patterns indicate cross-border impacts on various sectors. This study assessed the impact of secondary hard substrate, as being introduced into marine ecosystems by the establishment of wind farm pillars, on the occurrence and distribution of the moon jelly Aurelia aurita in the southwestern Baltic Sea. A two-year data sampling was conducted with removable settlement plates to assess the distribution and population development of the scyphozoan polyps. The data collected from these samples were used to set up a model with Lagrangian particle technique. The results confirm that anthropogenic created hard substrate (e.g. offshore wind farms) has the potential to increase the abundance of the A. aurita population. The distribution of wind farm borne jellyfish along Danish, German and Polish coasts indicates conflicts with further sectors, mainly energy and tourism

Spin structure and longitudinal polarization of hyperon in e+e- annihilation at high energies

Longitudinal polarizations of different kinds of hyperons produced in e+e- annihilation at LEP I and LEP II energies in different event samples are calculated using two different pictures for the spin structure of hyperon: that drawn from polarized deep inelastic lepton-nucleon scattering data or that using SU(6) symmetric wave functions. The result shows that measurements of such polarizations should provide useful information to the question of which picture is more suitable in describing the spin effects in the fragmentation processes.Comment: 26 pages with 10 figures.

Impacto de Guadua paraguayana sobre remanescente de Floresta Ombrófila Mista Aluvial: uma abordagem biogeoquímica.

Guadua paraguayana Döll, um bambu nativo da porção meridional da América do Sul particularmente agressivo, está invadindo áreas de preservação permanente no segundo planalto paranaense, com supressão da vegetação instalada e modificações nos padrões de sucessão local. Após estabelecer sua autoecologia, para melhor avaliar seu impacto sobre um dos últimos remanescentes da Floresta Ombrófila Mista Aluvial (FOMA), principalmente na ciclagem de nutrientes e no fluxo de carbono orgânico para o ambiente, estudou-se a composição química da espécie, a produção e decomposição de serapilheira e a distribuição das raízes. A área em estudo (25º 13?20,8? S e 50º04?26,8? W, Ponta Grossa/PR) é uma planície de inundação degradada às margens do rio Tibagi. Os valores anuais de produção de serapilheira de G. paraguayana foram estimados em 7.500 kg/ha, com meia vida superior a 260 dias para os limbos e 360 dias para as bainhas foliares. No período analisado, as folhas retornaram ao ambiente 164,27 kg/ha de macronutrientes. Com base na concentração de carbono da folha, o fluxo de carbono orgânico da vegetação para o solo foi estimado em 2.800 kg/ha/ano. Em comparação com os valores de FOMA melhor preservada, a presença dominante desse bambu reduz a quantidade de nutrientes e de carbono devolvidos ao meio

New Constraints on Dispersive Form Factor Parameterizations from the Timelike Region

We generalize a recent model-independent form factor parameterization derived from rigorous dispersion relations to include constraints from data in the timelike region. These constraints dictate the convergence properties of the parameterization and appear as sum rules on the parameters. We further develop a new parameterization that takes into account finiteness and asymptotic conditions on the form factor, and use it to fit to the elastic \pi electromagnetic form factor. We find that the existing world sample of timelike data gives only loose bounds on the form factor in the spacelike region, but explain how the acquisition of additional timelike data or fits to other form factors are expected to give much better results. The same parameterization is seen to fit spacelike data extremely well.Comment: 24 pages, latex (revtex), 3 eps figure

The impact of hyperhidrosis on patients' daily life and quality of life : A qualitative investigation

Background: An understanding of the daily life impacts of hyperhidrosis and how patients deal with them, based on qualitative research, is lacking. This study investigated the impact of hyperhidrosis on the daily life of patients using a mix of qualitative research methods. Methods: Participants were recruited through hyperhidrosis patient support groups such as the Hyperhidrosis Support Group UK. Data were collected using focus groups, interviews and online surveys. A grounded theory approach was used in the analysis of data transcripts. Data were collected from 71 participants, out of an initial 100 individuals recruited. Results: Seventeen major themes capturing the impacts of hyperhidrosis were identified; these covered all areas of life including daily life, psychological well-being, social life, professional /school life, dealing with hyperhidrosis, unmet health care needs and physical impact. Conclusions: Psychosocial impacts are central to the overall impacts of hyperhidrosis, cutting across and underlying the limitations experienced in other areas of life.Peer reviewe

Efficiency of sampling methods to monitor the bacterial contamination of pork carcasses before and after chilling

The aim of the study was to compare the efficiency of destructive (excision) and non-destructive (swabbing and sponging) sampling methods to enumerate aerobic mesophilic microorganisms, Enterobacteriaceae and to detect Salmonella on the surface of pork carcasses. In three slaughterhouses, a total of 720 half-carcasses were sampled before and after chilling. On each half-carcass, four sites were sampled by both destructive and non-destructive techniques, for a respective total surface of 25 and 400 cm2
