TiCl4, ammonia, inorganic salts as raw material, nanometer composite-crystal TiO2 powders were synthesized by two-step chemical method. Precursors were crystallized with different phase and stable composite-crystal TiO2 with anatase and rutile phase was prepared at low temperature. Quantitative control of crystal phase was realized. Remarkable factors includ...

BACKGROUND A limited number of studies suggest that ambient temperature contributes to suicide; these studies typically focus on a single nation and use temporally and spatially aggregated data. OBJECTIVE We evaluated the association between ambient temperature and suicide in multiple cities in three East Asian countries. METHODS A time-stratified case-crossover method was used to explore t...

The population dynamics of fruit fly Bactrocera zonata Saunders (Diptera: Tephritidae) was carried out by installing "Nauroji-Stonehouse Fruit Fly Trap" in the mango orchard organic farm, Navsari Agricultural University, Navsari, Gujarat, India during period 2021-22. B. prevailed throughout year with its peak activity from 14th SMW to 31st which coincided fruiting and harvesting fruits. maximum...

BACKGROUND AND OBJECTIVES Substantial climate changes have led to the emergence and re-emergence of various infectious diseases worldwide, presenting an imperative need to explore the effects of meteorological factors on serious contagious disease incidences such as that of meningococcal meningitis (MCM). METHODS The incidences of MCM and meteorology data between 1981 and 2010 were obtained f...

daily sunshine duration is one of the factors influencing the size of solar panels in a photovoltaic system. when the system is designed and the number of system components is calculated, the average of sunshine hours is usually used. however, sunshine hours are less than average and we are faced to shortage and surplus of electricity in the winter and summer, respectively. in this paper due to...

This study develops statistical and machine learning models based on discriminant analysis, logistic regression a support vector (SVM) to predict the occurrence of radiation fog in Japan. The selection suitable set explanatory variables for was made using Akaike information criterion (AIC). accuracies three were measured compared. To determine optimum combination variables, temperature, humidit...

Heterothermic insects like honeybees, foraging in a variable environment, face the challenge of keeping their body temperature high to enable immediate flight and to promote fast exploitation of resources. Because of their small size they have to cope with an enormous heat loss and, therefore, high costs of thermoregulation. This calls for energetic optimisation which may be achieved by differe...
