This research will determine the actuarially fair premium rate, both theoretically and using the data of rice harvest yield in Central Java Province from 1990-2017. The calculation, employing the rice harvest yield data, results in the premium rate. The farmers must pay for each hectare from IDR 56,000 (minimum) to IDR 161,600 (maximum) with an average value of IDR 110,750.Meanwhile,the standard deviation principle used, the premium results between IDR 78,151 and IDR 143,349.

In this paper, a maximum power point tracking (MPPT) scheme is proposed for permanent magnet synchronous generator (PMSG) wind turbine systems. With this method, an adaptive compensation control is considered to improve the system dynamic response and therefore more energy yield can be extracted from the wind turbine, depending on a trade-off between the system dynamic behavior and the transient load of the drive train.

The Tinospora sinensis Merr. was ultrasonically extracted using 80% ethanol at a temperature of 50°C. The resulting solution was distilled to remove the solvent under reduced pressure, yielding the extract. The extract was then dissolved in distilled water, and this solution was administered to the experimental mice. The results showed that even at the maximum allowable dose, no mice experienced mortality.

The synthesis, photophysical and electrochemical properties of hexyl thiophene substituted thieno[b]-fused BODIPY structure are reported within this work. One such derivative, HTFBod, has been studied, which is one of the rare compounds that has a maximum absorbance wavelength greater than 750 nm among fused BODIPY compounds. In addition, it preserves its significant spectral properties such as high molar absorptivity and fluorescence quantum yield.

The results showed that soybean planted early (i.e. mid-June) suffered less PSB attack resulting in low seed damage and high yields. This suggests that mid-June is the best period to plant soybean to avoid PSBs for maximum yields in northern Ghana.

Three new asymmetrical photochromic diarylethenes containing a variable heteroaryl ring and a quinoline unit were synthesized and their structures were determined by single-crystal X-ray diffraction analysis. Their properties, including photochromism, acidichromism, and fluorescence, were investigated systematically. For these diarylethenes, the one with an indole moiety had the largest absorption maximum, cyclization quantum yield, photoconversion ratio, emission peak, and fluorescent modulation efficiency.

The brittle fracture mode by cleavage is accounted for by Ritchie–Knott–Rice's deterministic maximum principal stress criterion (Ritchie et al., 1973). The wellknown problem of mesh dependence associated with softening material behavior is remedied by using an integral type nonlocal formulation similar to that presented in Tvergaard and Needleman (1995).

Open-field farming involves successive major processes such as preparation of soil, planting the seed, adding pesticides and fertilizers, irrigation, cultivation, and harvest. The main aim of all processes is to achieve maximum yield out of the available agricultural landscape. It is necessary to collect geo-referenced descriptive data on soil characteristics, such as soil penetration resistance and electrical conductivity before starting all these processes.

1-Methyl-2-(2-(prop-2-yn-1-yloxy)benzylidene)hydrazine analogues were readily prepared in good yields by the reaction of 2-(prop-2-yn-1-yloxy)benzaldehydes and methyl hydrazine. The reaction tolerates a variety of substituents on the 2-hydroxybenzaldehyde to form nitro-, halo-, methoxy-, and naphthyl-substituted 1-methyl-2-(2-(prop-2-yn-1- yloxy)benzylidene)hydrazines.

2-Substituted 8-propargyloxyquinoline derivatives have been synthesized from 2-substituted-8-hydroxyquinolines by O-propargylation method (30%–98% yields). The newly synthesized compounds were tested for in vitro antioxidant activities such as DPPH radical scavenging, ferrous chelating, and reducing power activities. The maximum radical scavenging (46.5%) and reducing power activities were obtained from 1 and maximum ferrous chelating effect was obtained from 6 (72.1%) at the concentration of 500 µg/mL. To indicate DNA binding activity of the complexes calf thymus DNA was used.

Schiff base derivatives with anthracene- and pyrene-based units, A1-A6 and P1-P6 were synthesized (89%–99% yields). Schiff base derivatives were designed to possess an heterocyclic moiety on one side to enhance the coordination ability towards metals. To investigate the biological assay of the newly synthesized compounds, their DPPH (2,2-diphenyl-1-picrylhydrazyl) radical scavenging, metal chelating, reducing power, antibacterial and DNA binding activities were tested. A6 (63.1%) showed the maximum free radical scavenging activity among all.

The results showed that the active component Zr(SO4 )2 was successfully adhered to the mesoporous SiO2 , and the acid amount of Zr(SO4)2/SiO2 increased with the increasing of the Zr(SO4)2 loadings. Finally, the wheat stalk was used as raw material and depolymerized over Zr(SO4)2/SiO2 to produce ethyl levulinate (EL). The reaction mixture was separated and purified by filtration and vacuum distillation. The kinetic characteristics and the reaction pathway were also studied. A comparative study showed that 20 wt.% Zr(SO4)2/SiO2 exhibited higher catalytic activity.

Flowers are regarded as a symbol of love, beauty and a gift of nature. Flowers are used by us to provoke the feelings of love and happiness because they have the power to make people happy and cheerful. A study was carried out to review on effect of pinching on flower crop. The number of experiments reviewed that pinching after 4 to 6 week after transplanting gives number of leaves, number of primary branches, plant spread, maximum number of flowers, number of seeds per flower, test weight and seed yield per ha with better seed quality parameters.

Investigations were carried out on fifteen cultivars of strawberry for growth, yield and quality characters. The results recorded reveal that maximum plant height (35.30cm) and number of runners (8.82) were in cultivar Catskill, however the average plant spread was found to be highest in Curaltar (34.16 cm) while cultivar Camarosa recorded maximum leaf area (42.86 cm2 ). Longest cultivar duration of bloom (85.30 days) was observed in cultivar Everly and minimum (55.38 days) in cultivar Winter Dawn.
