In a multi input and output (MIMO) process mathematical modeling of the physical systems has gained importance due to the complexity of interactions within the system. All the parameters used in a model cannot be determined accurately. The major problem in a multivariable process is that loop interaction can arise and cause difficulty in feedback control… (More)
Significant effect of water stress conditions were observed on morphological and physiological growth parameters of tea (Camellia sinensis). Water stress tolerant tea clones suitable for hilly areas have been identified in this study. The influence of different levels of water deficit on physiological and morphological parameters in tea [Camellia sinensis… (More)
Fine roots (≥1 mm) production in Chir Pine (Pinus roxburghii Sarg.) forests was estimated across three different seasons for one year at four sites located between 1600–1850 meters elevation on two contrasting aspects. At each site three different slope positions (ridge slope, mid hill slope and hill base) were selected for the study. The tree density… (More)
We studied variations in tree biomass and carbon sequestration rates of Chir Pine (Pinus roxburghii. Sarg.) forest in three categories of forest disturbance, protected, moderately disturbed, and highly disturbed. In the first year, total biomass was 14.7 t·ha−1 in highly disturbed site, 94.46 t·ha−1 in moderately disturbed forest, and 112.0 t·ha−1 in… (More)
The effect of soil solarization on physical, chemical and biological properties of soil was studied, along with the response of cauliflower seedlings following solarization. Nursery beds were covered with transparent polyethylene sheet and soil temperature and moisture were recorded. Soil samples were collected five times for analysis. Three cauliflower… (More)
Two conformational polymorphs of novel 2-[2-(3-cyano-4,6-dimethyl-2-oxo-2H-pyridin-1-yl)-ethoxy]-4,6-dimethyl nicotinonitrile have been developed. The crystal structure of both polymorphs (1a and 1b) seems to be stabilized by weak interactions. A difference was observed in the packing of both polymorphs. Polymorph 1b has a better binding affinity with the… (More)
Series of 1,5-diaryl pyrazole ester derivatives have been synthesized and found to contain potent inhibitory activity against cyclooxygenase-2 (COX-2) enzyme. The article describes synthesis of the target pyrazole analogs and biological assay using Carrageenan induced rat paw for investigation.
The crystal structures of 1-[5-[4,6-bis(methylsulfanyl)-2H-pyrazolo[3,4-d]pyrimidin-2-yl]pentyl]-6-methylsulfanyl-4-(pyrrolidin-1-yl)-1H-pyrazolo[3,4-d]pyrimidine, C(22)H(29)N(9)S(3), and 6-methylsulfanyl-1-[5-[6-methylsulfanyl-4-(pyrrolidin-1-yl)-2H-pyrazolo[3,4-d]pyrimidin-2-yl]pentyl]-4-(pyrrolidin-1-yl)-1H-pyrazolo[3,4-d]pyrimidine, C(25)H(34)N(10)S(2),… (More)
