Study design was cross sectional; samples of the study were 80 families (53 Juragan and 27 Janggol) selected by using proportional random sampling method, and conducted in Pangandaran District, Ciamis Regency in May 2009. The study indicated that most of samples categorized as small size family (family members approximately 4 people) and had length of formal education less than 9 years. The average of family asset owned by Juragan was twice than that of Janggol. The first variable, Family strengths, consisted of physical, social, and psychological components. There was no significant difference in psychological and social strengths between Juragans and Janggols; however regarding the physical strengths, Juragan had higher level than Janggols. It was found that Juragan had higher average per capita income and family asset than Janggol. The next variable, social support comprised emotional, economic, and information support. Fishermen families received social support from the extended family, neighbors, and community agencies/governments, in terms of a sense of security and empathy, financial assistance and information about weather changes, in this matter, there was no difference between Juragan and Janggol. The last variable, social capital was divided into local associations and community characters. The number of local associations joined by the samples ranged from one to four. Generally, samples actively participated in every meeting conducted by the associations, but the number of Janggol who did not feel the benefit of such associations was three times as much as Juragan. Moreover, community characters were divided into the trust, solidarity, and morale. At high categorized, the Janggols had twice higher solidarity than the Juragans. Different test showed that Juragan involved in much more associations than Janggols. Correlation test showed that samples who had better social support possessed a better family social capital (particularly in participation in local associations) and better family income and consequently possessed better family physical strength, while samples who had better social capital had better family physical strengths. The result of study indicates the importance of social capital and social support improvement for fishermen’s family as part of the Program for Strengthening and Empowering the Family conducted by both BKKBN (National Agency for Population and Family Planning) and DKP (Ministry of Marine and Fisheries).

Published: March 2017

Typical vegetation of arid environments consists of few dominant species highly threatened by climate change. Jurema preta (Mimosa tenuiflora (Willd.) Poiret) is one of these successful species that now is dominant in extensive semiarid areas in the world. The development of a simple bioclimatic model using climate change scenarios based on optimistic and pessimistic predictions of the Intergovernmental Panel on Climate Change (IPCC) shown as a simple tool to predict possible responses of dominant species under dry land conditions and low functional biodiversity. The simple bioclimatic model proved satisfactory in creating climate change scenarios and impacts on the canopy temperature of Jurema preta in semiarid Brazil. The bioclimatic model was efficient to obtain spatially relevant estimations of air temperature from determinations of the surface temperature using satellite images. The model determined that the average difference of 5oC between the air temperature and the leaf temperature for Jurema preta, and an increase of 3oC in air temperature, promote an increase of 2oC in leaf temperature. It leads to disturbances in vital physiological mechanisms in the leaf, mainly the photosynthesis and efficient use of water.

O arranjo, orientação e organização dos grãos do solo de diferentes características são fatores determinísticos da estrutura do solo, como também, da porosidade desse meio. A porosidade possui forte influência na aeração, na transferência de água/solutos/gases/calor, na resistência à penetração e ramificação de raízes e no desenvolvimento de microorganismos, podendo ser um elemento importante na determinação da qualidade de um solo. A avaliação morfométrica do espaço poroso de um Neossolo Regolítico Eutrófico (NRe) utilizando a Microtomografia Computadorizada de Raios-x é objetivo deste estudo, onde foram analisados os atributos físicos do solo e os tamanhos, as formas e as inclinações dos vazios intra-agregados. O NRe apresentou uma porosidade de 28% (27% de vazios inter-agregados e 1% de vazios intra-agregados) e 73% de agregados. Cerca de 73% dos vazios intra-agregados possuem volumes entre 1,278 x 10-4 a 6,545 x 10-2 mm³. Há um maior volume de vazios complexos e alongados, os quais favorecem a condução de água pelo solo, e um maior volume de poros achatados, podendo indicar um certa compactação desse meio. Os vazios apresentaram-se em sua maioria como quase horizontais e inclinado, resultado da resistência a penetração de raízes devido a presença de lamelas argilosas nesse solo. A aplicação de microtomografia computadorizada de raios-X se mostrou eficiente na caracterização micromorfométrica da porosidade do solo.

Galls are characterized by inducing cellular differentiation (hyperplasia or hypertrophy) resultant of the action of some organisms, mainly insects, on structures/organs of their host plants. The galls cause physiological changes in host plants, altering host traits, and their growth and survival. The early abscission of galled plant organs can be a form of plant defense. Therefore, the galls decayed more slowly than the healthy leaves, or the surrounding healthy leaf tissue in some abscised galled leaves, forming “green island galls”. This study reported an instance where the host plant Miconia cinnamomifolia (Melastomataceae) abscises leaves galled by an unidentified coleopteran’s gall on the soil of a fragment of Atlantic Forests, Brazil. Once on the forest soil galls were exposed to a new set of potential natural enemies, as pathogens and predators. Consequently, larval survival decrease of 79% to 36% in four months and fungal infestation increase of 2% to 21%. Neither size nor weight of the galls differed between categories of mortality factors and larval survival. It was discussed the adaptive nature of the “Green Island Effect” as a counter-response of gallers to leaf abscission, which is a known plant defense strategy.

Nas florestas tropicais, o efeito de borda é considerado um dos fatores que afetam o equilíbrio do ecossistema. Como consequência desse distúrbio, inúmeros grupos de organismos têm suas populações afetadas. Os líquens são particularmente sensíveis às mudanças microclimáticas, pois retiram nutrientes diretamente da atmosfera e apresentam pequena capacidade de regulação de perda e ganho de água. Eles são classificados quanto às formas e o crescimento. O objetivo deste trabalho foi testar se líquens com diferentes características morfo-anatômicas apresentam tolerância distinta às condições de borda florestal. A hipótese testada é de que líquens com características morfo-anatômicas que minimizem a perda de água são menos susceptíveis ao efeito de borda. Nas árvores amostradas foram amostrados 389 pontos com líquens do tipo “A” (líquens crostosos com córtex liso e sem protalos) e 123 com líquens do tipo B (líquens hidrófilos, sem córtex definido, que retêm água nos protalos). Embora não tenha havido relação entre a distância de borda e a cobertura dos liquens do tipo “A”, a cobertura relativa dos líquens do tipo B diminuiu com o aumento da distância da borda. Houve relação negativa entre a distância da borda e a temperatura ao meio dia e foi encontrada uma relação entre a distância da borda e a umidade relativa do ar. Nos 10 primeiros metros de distância da borda os líquens do tipo B apresentaram uma maior cobertura relativa, já nas distâncias subsequentes houve uma inversão, onde os líquens do tipo A passaram a ter maior cobertura relativa.

The increasingly large role of financial intermediaries in promoting firms' innovation and internationalization has led to great research interest. China has faced mounting pressure to take entrepreneurial finance and innovation seriously. Little is known about entrepreneurial financiers' activities and performance. Focusing on entrepreneurial financiers' activities in the Yangtze River Economic Belt, this study investigates how they select projects and how well they perform in China. Evidence shows that various financiers serve in the financial system to nurture innovative entrepreneurial activities; they tend to focus on technology, and the major financiers vary with stage of industrial technological development. With the support of entrepreneurial finance, the invested firms in general maintain a sound growth momentum, but the foreign trade of relevant industries has not significantly increased and has even declined. The implication for industrial and international development policy is discussed.

Many Uralic languages have a rich morphological structure, but lack morphological analysis tools needed for efficient language processing. While creating a high-quality morphological analyzer requires a significant amount of expert labor, data-driven approaches may provide sufficient quality for many applications. We study how to create a statistical model for morphological segmentation with a large unannotated corpus and a small amount of annotated word forms selected using an active learning approach. We apply the procedure to two Finno-Ugric languages: Finnish and North Sámi. The semi-supervised Morfessor FlatCat method is used for statistical learning. For Finnish, we set up a simulated scenario to test various active learning query strategies. The best performance is provided by a coverage-based strategy on word initial and final substrings. For North Sámi we collect a set of humanannotated data. With 300 words annotated with our active learning setup, we see a relative improvement in morph boundary F1-score of 19% compared to unsupervised learning and 7.8% compared to random selection.

In the framework of the European research project LEMCOTEC, a section was devoted to the further optimization of the recuperation system of the Intercooled Recuperated Aero engine (IRA engine) concept, of MTU Aero Engines AG. This concept is based on an advanced thermodynamic cycle combining both intercooling and recuperation. The present work is focused only on the recuperation process. This is carried out through a system of heat exchangers mounted inside the hot-gas exhaust nozzle, providing fuel economy and reduced pollutant emissions. The optimization of the recuperation system was performed using computational fluid dynamics (CFD) computations, experimental measurements and thermodynamic cycle analysis for a wide range of engine operating conditions. A customized numerical tool was developed based on an advanced porosity model approach. The heat exchangers were modeled as porous media of predefined heat transfer and pressure loss behaviour and could also incorporate major and critical heat exchanger design decisions in the CFD computations. The optimization resulted in two completely new innovative heat exchanger concepts, named as CORN (COnical Recuperative Nozzle) and STARTREC (STraight AnnulaR Thermal RECuperator), which provided significant benefits in terms of fuel consumption, pollutants emission and weight reduction compared to more conventional heat exchanger designs, thus proving that further optimization potential for this technology exists.
Vitamin E Nicotinate

Published: March 2017

Vitamin E refers to a family of compounds that function as lipid-soluble antioxidants capable of preventing lipid peroxidation. Naturally occurring forms of vitamin E include tocopherols and tocotrienols. Vitamin E in dietary supplements and fortified foods is often an esterified form of α-tocopherol, the most common esters being acetate and succinate. The vitamin E esters are hydrolyzed and converted into free α-tocopherol prior to absorption in the intestinal tract. Because its functions are relevant to many chronic diseases, vitamin E has been extensively studied in respect to a variety of diseases as well as cosmetic applications. The forms of vitamin E most studied are natural α-tocopherol and the esters α-tocopheryl acetate and α-tocopheryl succinate. A small number of studies include or focus on another ester form, α-tocopheryl nicotinate, an ester of vitamin E and niacin. Some of these studies raise the possibility of differences in metabolism and in efficacy between vitamin E nicotinate and other forms of vitamin E. Recently, through metabolomics studies, we identified that α-tocopheryl nicotinate occurs endogenously in the heart and that its level is dramatically decreased in heart failure, indicating the possible biological importance of this vitamin E ester. Since knowledge about vitamin E nicotinate is not readily available in the literature, the purpose of this review is to summarize and evaluate published reports, specifically with respect to α-tocopheryl nicotinate with an emphasis on the differences from natural α-tocopherol or α-tocopheryl acetate.
SNP Discovery Using a Pangenome: Has the Single Reference Approach Become Obsolete?
Authors: Hurgobin Bhavna , Edwards David
Published: March 2017

Increasing evidence suggests that a single individual is insufficient to capture the genetic diversity within a species due to gene presence absence variation. In order to understand the extent to which genomic variation occurs in a species, the construction of its pangenome is necessary. The pangenome represents the complete set of genes of a species; it is composed of core genes, which are present in all individuals, and variable genes, which are present only in some individuals. Aside from variations at the gene level, single nucleotide polymorphisms (SNPs) are also an important form of genetic variation. The advent of next-generation sequencing (NGS) coupled with the heritability of SNPs make them ideal markers for genetic analysis of human, animal, and microbial data. SNPs have also been extensively used in crop genetics for association mapping, quantitative trait loci (QTL) analysis, analysis of genetic diversity, and phylogenetic analysis. This review focuses on the use of pangenomes for SNP discovery. It highlights the advantages of using a pangenome rather than a single reference for this purpose. This review also demonstrates how extra information not captured in a single reference alone can be used to provide additional support for linking genotypic data to phenotypic data.

Soil-structure interaction (SSI) could affect the seismic response of structures. Since liquid storage tanks are vital structures and must continue their operation under severe earthquakes, their seismic behavior should be studied. Accordingly, the seismic response of two types of steel liquid storage tanks (namely, broad and slender, with aspect ratios of height to radius equal to 0.6 and 1.85) founded on half-space soil is scrutinized under different earthquake ground motions. For a better comparison, the six considered ground motions are classified, based on their pulse-like characteristics, into two groups, named far and near fault ground motions. To model the liquid storage tanks, the simplified mass-spring model is used and the liquid is modeled as two lumped masses known as sloshing and impulsive, and the interaction of fluid and structure is considered using two coupled springs and dashpots. The SSI effect, also, is considered using a coupled spring and dashpot. Additionally, four types of soils are used to consider a wide variety of soil properties. To this end, after deriving the equations of motion, MATLAB programming is employed to obtain the time history responses. Results show that although the SSI effect leads to a decrease in the impulsive displacement, overturning moment, and normalized base shear, the sloshing (or convective) displacement is not affected by such effects due to its long period.
Potential Enhanced Survivorship of Crown of Thorns Starfish Larvae due to Near-Annual Nutrient Enrichment during Secondary Outbreaks on the Central Mid-Shelf of the Great Barrier Reef, Australia
Authors: Brodie Jon , Devlin Michelle , Lewis Stephen
Published: March 2017

The Great Barrier Reef (GBR) is currently experiencing widespread crown of thorns starfish (CoTS) outbreaks, as part of the fourth wave of outbreaks since 1962. It is believed that these outbreaks have become more frequent on the GBR and elsewhere in the Indo-Pacific and are associated with anthropogenic causes. The two widely accepted potential causes are (1) anthropogenic nutrient enrichment leading to the increased biomass of phytoplankton, the food of the planktonic stage of larval CoTS; and (2) the overfishing of predators in the juvenile to adult stages of CoTS, for example, commercially fished species such as coral trout. In this study, we show that the evidence for the nutrient enrichment causation hypothesis is strongly based on a large number of recent studies in the GBR. We also hypothesise that secondary outbreaks in the region between Cairns and Townsville can also be enhanced by nutrient enriched conditions associated with the annual nutrient discharge from Wet Tropics rivers.
