Support for enterprise applications in SOFA 2
No full textTitle: Support for Enterprise Applications in SOFA 2 Author: Tibor Blénessy Department: Department of Distributed and Dependable Systems Supervisor of the master thesis: RNDr. Tomáš Bureš, Ph.D. Abstract: Industry standards defining various aspects of enterprise systems were developed in order to make development of such systems faster and to increase interoperability. For systems created with Java platform, these standards are contained under Java Enterprise Edition. SOFA 2 component system provides a solid base for development of ex- tensive component oriented systems. Goal of this work is to propose and empirically verify the possibility of integration of existing industry standards for enterprise applications in SOFA 2. Proposed solution extends SOFA 2 with components for web user in- terfaces based on Java Servlet API standard and with components for persisting data into relational databases based on Java Peristence API. In addition, it integrates core technologies from the Java Enterprise Edition platform, which should make integration of further standards easier. Keywords: enteprise applications, component system, SOFA 2, Java E
Modular Sofa Technology Development
No full textMaģistra darba “Modulāra dīvāna tehnoloģijas izstrāde” mērķis ir veicināt ilgtspējīgu resursu izmantošanu mēbeļu ražošanas nozarē. Darba teorētiskajā daļā tika veikts pētījums par mēbeļu ražošanu ietekmējošajiem elementiem, un noteikta konkrētā problēma: mēbeles nav iespējams ekonomiski pielāgot mainīgajām dizaina un funkcionalitātes prasībām. Darba praktiskajā daļā, izvērtējot un salīdzinot četras iespējamās projekta alternatīvas konkrētās problēmas risināšanai, autore izstrādāja projekta priekšlikumu un rokasgrāmatu modulāra dīvāna tehnoloģijas izstrādei, kura ļautu pēc nepieciešamības pielāgot dīvāna formu, izmēru, funkcionalitāti, materiālu un krāsu. Maģistra darbs sastāv no 97 lapām, 16 tabulām, 19 attēliem un 33 pielikumiem.The objective of the master’s thesis “Modular sofa technology development” is to promote sustainable use of resources in the furniture manufacturing industry. The theoretical part of the thesis contains a study on the elements influencing the production of furniture, which served as the basis for identifying the specific problem: adapting furniture to the changing requirements of design and functionality is not economically feasible. In the practical part of the thesis, after evaluating and comparing four possible project alternatives for solving the specific problem, the author developed a project proposal and a project handbook for the development of modular sofa technology, which would allow the adjustment of its shape, size, functionality, material and colour as needed. The master’s thesis consists of 97 pages, 16 tables, 19 pictures and 33 appendices

Predictors of Stunting, Wasting and Underweight among Tanzanian Children Born to HIV-Infected Women.
No full textChildren born to human immunodeficiency virus (HIV)-infected women are susceptible to undernutrition, but modifiable risk factors and the time course of the development of undernutrition have not been well characterized. The objective of this study was to identify maternal, socioeconomic and child characteristics that are associated with stunting, wasting and underweight among Tanzanian children born to HIV-infected mothers, followed from 6 weeks of age for 24 months. Maternal and socioeconomic characteristics were recorded during pregnancy, data pertaining to the infant's birth were collected immediately after delivery, morbidity histories and anthropometric measurements were performed monthly. Multivariate Cox proportional hazards methods were used to assess the association between potential predictors and the time to first episode of stunting, wasting and underweight. A total of 2387 infants (54.0% male) were enrolled and followed for a median duration of 21.2 months. The respective prevalence of prematurity (<37 weeks) and low birth weight (<2500 g) was 15.2% and 7.0%; 11.3% of infants were HIV-positive at 6 weeks. Median time to first episode of stunting, wasting and underweight was 8.7, 7.2 and 7.0 months, respectively. Low maternal education, few household possessions, low infant birth weight, child HIV infection and male sex were all independent predictors of stunting, wasting and underweight. In addition, preterm infants were more likely to become wasted and underweight, whereas those with a low Apgar score at birth were more likely to become stunted. Interventions to improve maternal education and nutritional status, reduce mother-to-child transmission of HIV, and increase birth weight may lower the risk of undernutrition among children born to HIV-infected women
Apigenin, an Anticancer Isolated from Macaranga gigantifolia Leaves
No full textApigenin, a flavonoid compound has been isolated from the ethyl acetate fraction of methanol extract of Macaranga gigantifolia leaves. Isolation and purification of apigenin conducted using column and centrifugal chromatography and chemical structure characterized based on spectroscopic data. In vitro anticancer activity test against murine leukimia P-388 cell line showed potential activity as anticancer with IC50 14.13 µg/mL

No full textCreative Design Based on Mechanism Regeneration of a Sofa Bed
No full textCreative design plays a quite important role in mechanical product processing, which affects the mechanical development of all over the country. Much research on the mechanical design is carried on. The paper is mainly based on Yan’s Creative Mechanism Design Methodology, in which the author carries out some research in Type Synthesis based on the Number Synthesis Method. And kinematic chains of eight links and ten joints can be gained from embryo graphs. In the article, the author proposes a systematic method for the creation of a sofa bed. In the process, some rules are brought in, and the original structure is changed for other structures with the same functions but different shapes. At last, many probable schemes different from the original mechanism are obtained. The next step is to choose the most proper scheme in order to carry on the further analysis.</jats:p
Aktivitas Antioksidan Dan Toksisitas Ekstrak Air Dan Etanol Daun Benalu (Dendrophthoe Pentandra L. Miq) Yang Tumbuh Pada Berbagai Inang
No full textMistletoes are used traditionally in Indonesiaas medicinal plant, one of this as anticancer. Cancer isone of degenerative diseases could be triggered by toomuch free radicals in the body, whereas antioxidantcould reduced the risk of degenerative diseases.Mistletoes reposted content flavonoids which known have antioxidant activity. Mistletoe potency as drugmaterial should be studied sa the utilization ofmistletoe could be developed. Antioxidant activitytest using "DPPH free radical scavenger" methodand toxicity test using BSLT (Brine Shrimp LethalityTest) method had been conducted on water andethanol extracts of mistletoe Dendropthoe pentandra(L.) Miq.) that grown on various trees (star fruit,mango, cananga, 'duku, sour-sop, kepel, mahkotadewa, and tea). The result showed that ethanol andwater extracte-ofD, petandra on all host plants haveantioxidant activity (IC50 value between 6.4 - 51.8ug/mL). The result of toxicity test showed that ethanolextract of mistletoe on cananga, starfruit, kepel andmahkota dewa host plants have toxicity effect againstA. salina larvae with LCso value below 1000 ug/mL,nevertheless ethanol extract on others host plants andwater extract didn It give toxicity effect against A.salina larvae (LC50 > 1000 ug/mL)
