Detail investigation of equilibrium chemical reactions in WO3–H2O system using computer program FacktSage with the aim to establish influence of temperature and quantity of water on formation of compounds of H2WO4 and WO2(OH)2 as well as concomitant them compounds, evaporation products, decomposition and dissociation, that are contained in the program data base were carried out. Calculations in the temperature range from 100 to 3000 °С were carried out. The amount moles of water added to 1 mole of WO3 was varied from 0 to 27. It is found that the obtained data by the melting and evaporation temperatures of single-phase WO3 are in good agreement with the reference data and provide additionally detailed information on the composition of the gas phase. It was shown that under heating of 1 mole single-phase WO3 up to 3000 °С the predominant oxide that exist in gaseous phase is (WO3)2. Reactions of it formation from other oxides ((WO3)3 and (WO3)4) were proposed. It was established that compound H2WO4 is stable and it is decomposed on WO3 and H2O under 121 °C. Tungsten Oxide Hydrate WO2(OH)2 first appears under 400 °С and exists up to 3000 °С. Increasing quantity of Н2О in system leads to decreasing transition temperature of WO3 into both liquid and gaseous phases. It was established that adding to 1 mole WO3 26 mole H2O maximum amount (0,9044–0,9171 mole) WO2(OH)2 under temperatures 1400–1600 °С can be obtained, wherein the melting stage of WO3 is omitted. Obtained data also allowed to state that that from 121 till 400 °С WO3–Н2O the section in the О–W–H ternary system is partially quasi-binary because under these temperatures in the system only WO3 and Н2O are present. Under higher temperatures WO3–Н2O section becomes not quasi-binary since in the reaction products WO3 with Н2O except WO3 and Н2O, there are significant amounts of WO2(OH)2, (WO3)2, (WO3)3, (WO3)4 and a small amount of atoms and other compounds.

Farmers participation is crucial for succeeding in the implementation of agricultural insurance in Indonesia. The purposes of this research are analyzing farmers' form and level of participation and also identifying some factors affecting farmer’s participation in agricultural insurance. The research was conducted in Curug Bitung Village, District of Nanggung, Bogor Regency involving 40 respondents. Primary data includes farmers characteristics, farmers participation form and farmers participation level as program beneficiaries. The data were processed using multivariable linear regression test. The results showed that the intensity of communication, age, education level, income level and length of stay did not significantly affect the participation level of farmers whose majority were at the level of no participation. Non-compliance occurs during program implementation. The form of participation shown by farmers in the program is varied.Keywords:  agricultural insurance, internal and external factors, farmers' participation ABSTRAK Partisipasi petani menjadi hal yang penting dalam rangka menyukseskan penerapan asuransi pertanian di Indonesia. Tujuan penelitian ini adalah menganalisis bentuk dan tingkat partisipasi petani dalam asuransi pertanian serta mengidentifikasi faktor-faktor yang memengaruhi partisipasi petani dalam program asuransi pertanian. Penelitian dilakukan di Desa Curug Bitung, Kecamatan Nanggung, Kabupaten Bogor dengan melibatkan 40 responden. Data primer meliputi karakteristik petani, bentuk partisipasi petani dan tingkat partisipasi petani penerima program. Data diolah menggunakan uji regresi linier multivariable. Hasil penelitian menunjukkan intensitas komunikasi, usia, tingkat pendidikan, tingkat pendapatan dan lama tinggal tidak berpengaruh secara signifikan terhadap tingkat partisipasi petani yang  mayoritas berada pada tingkatan tidak ada partisipasi. Ketidaksesuaian banyak terjadi selama penyelenggaraan program. Adapun bentuk partisipasi yang ditunjukkan petani dalam program bervariasi.Kata kunci: asuransi pertanian, faktor internal-eksternal, partisipasi petani

Malaria in Bhutan has fallen significantly over the last decade. As Bhutan attempts to eliminate malaria in 2022, this study aimed to characterize the space–time clustering of malaria from 2010 to 2019. Malaria data were obtained from the Bhutan Vector-Borne Disease Control Program data repository. Spatial and space–time cluster analyses of Plasmodium falciparum and Plasmodium vivax cases were conducted at the sub-district level from 2010 to 2019 using Kulldorff’s space–time scan statistic. A total of 768 confirmed malaria cases, including 454 (59%) P. vivax cases, were reported in Bhutan during the study period. Significant temporal clusters of cases caused by both species were identified between April and September. The most likely spatial clusters were detected in the central part of Bhutan throughout the study period. The most likely space–time cluster was in Sarpang District and neighboring districts between January 2010 to June 2012 for cases of infection with both species. The most likely cluster for P. falciparum infection had a radius of 50.4 km and included 26 sub-districts with a relative risk (RR) of 32.7. The most likely cluster for P. vivax infection had a radius of 33.6 km with 11 sub-districts and RR of 27.7. Three secondary space–time clusters were detected in other parts of Bhutan. Spatial and space–time cluster analysis identified high-risk areas and periods for both P. vivax and P. falciparum malaria. Both malaria types showed significant spatial and spatiotemporal variations. Operational research to understand the drivers of residual transmission in hotspot sub-districts will help to overcome the final challenges of malaria elimination in Bhutan.

A workable “systems approach” ergonomics program must be comprehensive, yet practicable in application. In order of the evolutionary development of Fisher Body's Manufacturing Ergonomic Program, data analysis, workplace analysis, recommended changes, training, reporting and evaluating progress and future planning are discussed. Emphasis throughout is put on practical implementation.
