In this paper, we describe the design of a system, called ParaWeb, for utilizing Internet or intra-net computing resources in a seamless fashion. The goal is to allow users to execute serial programs on faster compute servers or parallel programs on a variety of possibly heterogeneous hosts. ParaWeb provides extensions to the javaprogramming environment (through a parallel class library) and the java runtime system that allow programmers to develop new java applications with parallelism in mind, or to execute existing java applications written using java's multithreading facilities in parallel. Some experimental results from our prototype implementation are used to demonstrate the potential of this approach.

The origin of potassic lavas with within-plate characteristics in island are settings is unclear. The volcanic complex of Ringgit-Beser, situated in eastern java, has erupted lavas of both normal island are calc-alkaline type and atypical potassic lavas, including some highly magnesian lavas. The occurrence of these primitive lavas gives an unusual insight into the source characteristics of the potassic lavas. The lavas from Ringgit-Beser have a wide range of K2O (1.1-6.4 wt.%) and MgO contents (18.0-1.6 wt.%). The most magnesian lavas have high Ni and Cr contents. The calc-alkaline lavas have incompatible trace element patterns typical of island are lavas with enrichments in large ion lithophile elements (LILE) and light rare earth elements (LREE) relative to high field strength elements (HFSE) and heavy REE (HREE). The potassic lavas may be divided into two series on the basis of Ba and Nb contents, with the enriched potassic (EK) series having higher Ba and Nb contents for a given MgO content than the potassic (K) series. The EK and K series lavas have some incompatible trace element ratios similar to within-plate lavas (e.g., high Ce/Pb, low LILE/HFSE ratios, and low B/Be). However, both the EK series and K series lavas have negative Ti and Zr anomalies, and the EK series lavas have high Ba/La similar to are lavas. There is little distinction in Sr and Nd isotopes between the K and EK series, but the calc-alkaline lavas have lower Sr-87/Sr-86 and higher Nd-143/Nd-144 ratios than the potassic lavas. The EK series lavas have lower Pb-206/Pb-204 and higher Pb-208/Pb-204 than the K series lavas, but similar Pb-207/Pb-204 ratios. The K series lavas define an almost horizontal trend in Pb-207-Pb-206 space. The Pb isotopic ratios indicate that the EK series lavas are derived from a single mantle source, whereas the K series originate from a mixture of two mantle components. Calc-alkaline lavas have Pb isotope ratios similar to other calc-alkaline and tholeiitic lavas f

Previous epidemiological, virological and clinical studies have documented a series of outbreaks of dengue fever and dengue haemorrhagic fever/dengue shock syndrome which occured in java, Indonesia in 1976-1978. In the current study we compare growth characteristics in cell culture, and nucleotide sequence data for the viral prM and E genes, of five low passage DEN-3 isolates obtained during these epidemics from clinically defined cases. All isolates had the same passage history: human sera were passed twice in mosquitoes and three times in a mosquito cell line (Aedes albopictus, C 6/36 cells). Growth differences were observed between individual isolates in Vero cells;growth differences were not observed in C 6/36 cells. Nucleotide sequencing of the prM and E gene region indicated that no two isolates were identical (sequence divergence ranged from 0.4 to 1.6% in pairwise comparisons) but that they were closely enough related to present a single genetic type. There were one or two differences in deduced amino acid sequence in E between isolates. Differences were at residues 65, 187, 298 or 443. One isolate differed from all others at residue 16 in the M protein. No relationship was apparent between the amino acid sequence of M or E and the nature of the disease profile, the year of isolation or the geographic region of isolation. The isolates showed 3.5 to 4.4% nucleotide sequence divergence from the highly-adapted H 87 prototype, isolated in the Philippines in 1956. The isolates showed a total of twelve common amino acid differences in prM and E proteins from H 87. Ten of these twelve residues were at positions which differed between the four dengue serotypes. Two differences (at residues 37 in M and 293 in E) were at positions which are conserved in sequence between the four dengue serotypes. The data are discussed in relation to the dengue outbreaks in java in the period 1976-1978.

Spatial distribution pattern of the brown planthopper (BPH) was analyzed at 9 experimental fields in the northern part of West java during two consecutive rice cropping seasons, i.e., wet and dry seasons. The population of each developmental stage and wing form of BPH at each location showed consistent departure from the random (Poisson) distribution, the variances of the densities in most cases exceeding their means. Namely, the distribution pattern of BPH per hill of rice plant was found to have a general tendency to be aggregated or contagious and to fit fairly well to the negative binomial model. The tendency for aggregation was further confirmed by both the .beta.-values of .ovrhdot.m-m regression being larger than unity and the CA-values being larger than zero for each developmental stage. Although significant variations in the distribution pattern as measured by .beta.- or CA-value were observed between different developmental stages, between wing forms and among locations, the degree of aggregation for a given developmental stage at each experimental field remained fairly stable throughout the crop period, despite wide temporal changes in population density. Possible factors to explain these characteristics of the spatial distribution pattern of the PBH in West java were discussed with reference to the process generating it.

Observations and experiments on several species of Musaceae [Macroglossus-acuminata, M. balbisiana, M. halabanensis, M. ornata, M. textilis, M. coccinea, Ensete glaucum and E. ventricosum] in West java and central Sumatra showed that the species with pendent inflorescences are pollinated by macroglossine bats, principally by the long-tongued fruit bats, Macroglossus minimus and Eonycteris spelaea. Among the species with an erect inflorescence Musa velutina proves to be self pollinating, while M. salaccensis has sunbirds (Nectariniidae) and tree shrews (Tupaia) as pollinators. A discussion on pollination in this family is presented in this paper.

Táto diplomová práca sa zaoberá meraním výkonu a profilovaním systému CloverETL pre spracovanie dát. Podstatou je navrhnutie spôsobu merania výkonu prostredia a profilovania systému CloverETL. Problém bol vyriešený návrhom a implementáciou aplikácie, ktorá na základe nameraných dát a ich analýzy zistí maximálnu priepustonsť systému a sleduje zmeny výkonnosti systému. Výhodou je možnosť porovnať prostredia na ktorých beží systém CloverETL a využitie aplikácie pri automatizovanom testovaní vo firme. Vytvorené ETL Grafy boli otestované počas vývoja a sú súčasťou výsledku diplomovej práce.
