Life Values in the Proverbs used in Vilavangodu Region

Proverbs is one of the literary forms.  Like folk songs, folk tales, fairy tales etc., proverbs belong to the genre of oral literature. A proverb is a language that originates from primitive knowledge. Describing an object in one or two lines without directly describing it is called riddles. In Tamil it is called pisi or nodi. These riddles help in developing intellectual activities. Mothers use riddles to develop their child's intellectual power. Proverbs have appeared in all the languages and it is intertwined with people's lives. Proverbs have been used by the Tamil people since the ancient time itself. Proverbs is the shortest form of oral language-based folk idioms.  It has a great impact on people. Even today riddles are most commonly used by all humans. Our forefathers have used to say proverbs to indicate certain actions in the rural areas, to make comments and create awareness.  It is infused with experience and knowledge.  It can be said that it is the experience of a society's long-term circulation. In particular, proverbs describe something succinctly, clearly and beautifully. This article is in a position to establish how these proverbs are learned and used by the people Vilavankodu region

Consortium of Wallacean Microalgae in West Nusa Tenggara for Biodiesel Production

This study aims to explore the species richness of biodiesel-producing microalgae in the waters of West Nusa Tenggara to develop renewable energy source, environmentally friendly, and not compete in land use with the agricultural sector. Microalga samples were collected from various waters in West Nusa Tenggara Province using the concentration method. Species determination and data analysis of microalgae was carried out at the Biology Laboratory, University of Mataram to calculate the abundance of each species. The dominant species of biodiesel-producing microalgae were isolated and cultured by a closed culture system method. The oil content of the microalgae biomass produced was extracted by a liquid-liquid extraction method using n-hexane as a solvent. The results show that of the 49 species of marine microalgae identified in the waters of West Nusa Tenggara, there are 12 species of microalgae which are biodiesel producers. Of the 30 freshwater microalga species, only 8 species of microalgae are producers of biodiesel. The microalgae community of marine waters of West Nusa Tenggara is dominated by Bacteriastrumdelicatulum, B. variance, Chaetocerosaffinis, C. liciniosum, C. lorenzianum, Gyrosigma sp., Oscillatoria sp., Pseudonitzschia spp., and Thalassionemanitzschicoides, while freshwater microalgae communities are dominated by Microcystis aeruginosa, M. incerta, Nostoc sp., Pediastrumboryanum, and Staurastumcristatum. The dominant types of biodiesel-producing microalgae isolated and cultured are Chaetocerosamini, Nannochloropsisoculata and Nitzschia spp. Each cell density of C. amini, N. oculata, and Nitzschiaspp in culture 7 days after isolation was 3,600,960,000, 4,375,360,000, and 3,368,640,000 cells / liter respectively with oil content 34, 68, and 46%

Optimal electrification of off-grid smart homes considering flexible demand and vehicle-to-home capabilities

The emergence of novel demand-side management strategies is provoking that residential consumers cannot be longer categorized as inflexible loads. In that sense, new paradigms such as flexible demand and vehicle-to-home capabilities have appeared on pursuing a more efficient management of the different domestic assets such as smart appliances, small renewable generators and storage facilities. Consideration of such kind of management strategies plays a vital role on designing stages of electrifications systems for isolated homes. In this regard, a proper evaluation of possible demand-side capabilities enables a more accurate evaluation of the electrification project. This paper tackles this issue by developing a Mixed Integer Linear Programming formulation for optimal planning of electrification systems for off-grid dwellings. The developed framework allows to incorporate and analyse advanced demand-side strategies such as deferrable loads and vehicle-to-home processes by evaluating different project costs over various time horizons. The proposed approach is applied to a benchmark off-grid residential case study and various results are provided and analysed. As the most relevant result, it is worth remarking that total project cost can be reduced by ~21.2% and ~25.73% by considering flexible demand and vehicle-to-home capabilities, respectively. Nevertheless, the highest monetary savings were achieved when both strategies are jointly adopted, reducing the total project cost up to ~41.5%. The reported results demonstrate the importance of considering the different demand-side strategies on planning stages of electrification systems for off-grid dwellings

Perbandingan Hasil Belajar Biologi Siswa Kelas X Sman 2 Mataram Yang Belajar Melalui Pendekatan Nht Dan Tps Tahun Ajaran 2008/2009

: This research held to know the difference of student achievement in biological subject of class X of SMAN 2 Mataram thought using NHT and TPS approaches in the academic year of 2008/2009. The research population were all students of class X of SMAN 2 Mataram, and the samples of this research were class X4 and X8. Cluster random sampling was applied for determining the classes sample. Teaching approach for class X4 was NHT and TPS for class X8. Instruments of this research were test for cognitive achievement, observation sheets for students and teacher activities, assessment sheet for affective and psychomotor of students, and questioner for students response on both the teaching approaches. Data were analyzed statistically by using t-test at significant level of 5%. The results show that the average students achievement in class thought with NHT and TPS approaches were 65.44 and 76.19, respectively. Further analysis obtained the value of t-count was greater than t-table (3.384: 1.994). This means that the studentachievement was much greater in class thought by TPS compared to that of class thought by NHT approach. In other words, there was a significant different of student achievement thought by TPS and NHT

A trematode parasite derived growth factor binds and exerts influences on host immune functions via host cytokine receptor complexes

The trematode Fasciola hepatica is responsible for chronic zoonotic infection globally. Despite causing a potent T-helper 2 response, it is believed that potent immunomodulation is responsible for rendering this host reactive non-protective host response thereby allow- ing the parasite to remain long-lived. We have previously identified a growth factor, FhTLM, belonging to the TGF superfamily can have developmental effects on the parasite. Herein we demonstrate that FhTLM can exert influence over host immune functions in a host receptor specific fashion. FhTLM can bind to receptor members of the Transforming Growth Factor (TGF) superfamily, with a greater affinity for TGF-β RII. Upon ligation FhTLM initiates the Smad2/3 pathway resulting in phenotypic changes in both fibroblasts and macrophages. The formation of fibroblast CFUs is reduced when cells are cultured with FhTLM, as a result of TGF-β RI kinase activity. In parallel the wound closure response of fibroblasts is also delayed in the presence of FhTLM. When stimulated with FhTLM blood monocyte derived macrophages adopt an alternative or regulatory phenotype. They express high levels interleukin (IL)-10 and arginase-1 while displaying low levels of IL-12 and nitric oxide. Moreover they also undergo significant upregulation of the inhibitory recep- tor PD-L1 and the mannose receptor. Use of RNAi demonstrates that this effect is depen- dent on TGF-β RII and mRNA knock-down leads to a loss of IL-10 and PD-L1. Finally, we demonstrate that FhTLM aids newly excysted juveniles (NEJs) in their evasion of antibody- dependent cell cytotoxicity (ADCC) by reducing the NO response of macrophages—again dependent on TGF-β RI kinase. FhTLM displays restricted expression to the F. hepatica gut resident NEJ stages. The altered fibroblast responses would suggest a role for damp- ened tissue repair responses in facilitating parasite migration. Furthermore, the adoption of a regulatory macrophage phenotype would allow for a reduced effector response targetingjuvenile parasites which we demonstrate extends to an abrogation of the ADCC response. Thus suggesting that FhTLM is a stage specific evasion molecule that utilises host cytokine receptors. These findings are the first to clearly demonstrate the interaction of a helminth cytokine with a host receptor complex resulting in immune modifications that facilitate the non-protective chronic immune response which is characteristic of F. hepatica infection

THE TEMPERATURE ROTATION OF THE EASY AXIS DIRECTION IN DyFe3

Dans le composé DyFe3 on a déterminé, en utilisant l'effet Mössbauer, la direction d'un axe d'aimantation facile et les changements de cette direction avec la température. On a constaté qu'au-dessous de la température ambiante cet axe n'est parallèle à aucun axe crystallographique principal. En outre dans cette région de température où l'axe facile change de direction, on a observé le cône de dilatation thermique nulle.The orientation of easy magnetization axis and its temperature dependence was determined for DyFe3 by Mössbauer spectroscopy. Below the room temperature the easy axis does not overlap any of the principal crystallographic axes. In the temperature region where the easy axis rotates the zero thermal expansion cone was observed
