In Guangdong province, many hot springs were exploited and developed into popular places for tourist. In addition, hotels have been set up near hot spring sites to attract people, including local citizens, to spend their spare time inside these so-called “spring hotels”. In our study, indoor air quality was investigated in four hot spring hotels in Guangdong province, China. Measured indoor pol...

Winter survial during an annual cycle of temperateand boreal-zone woody perennials is a multicomponent response. Two of these components are: (1) the timing, rate, and extent of cold acclimation (CA; Box 1), and (2) plants’ ability to sufficiently maintain its freezing tolerance (FT) until the danger of killing frosts is passed which is determined by, among other factors, plants’ ability to res...

today there are different vibration isolators used in industries according to the weight and excitation frequency of the machines which have vibration. one of them is air spring which is in two types: convoluted air spring and membrane air spring. convoluted air springs are used to control vibrations in low frequency (usually lower than 10 hz) and the membrane ones are used in high frequency (u...

the seeds of three eucalyptus species (myrtaceae) (origin: australia), including:, eucalyptus loxophleba benth., eucalyptus microtheca f.muell.  and eucalyptus largiflorens f.muell. were cultivated in 1993-1994 at two research stations (shushtar and dezful) in khuzistan province (western south region of iran) and a research station (kashan) in isfahan province (central region of iran). these sp...

in order to evaluate the effects of foliar application of methanol and irrigation intervals on yield and yield components of chickpea cultivars a factorial experiment as split plots based on randomized complete block design with three replications was conducted in spring 2008 at the agricultural research station of ferdowsi university of mashhad. the treatments were 10 and 20 irrigation interva...

background & aim: ziziphora l. genus belongs to the lamiaceae family, which has important medicinal and aromatic plant species. in current study, essential oil chemical compositions of two ziziphora l. species (z. tenuior l. and z. clinopodioides lam.) were investigated. experimental: the flowering branches of z. tenuior and z. clinopodioides were collected in spring and summer 2011. the ae...

the leaves of four cultivated eucalyptus species, eucalyptus microtheca var. microtheca f. muell., eucalyptus spathulata, eucalyptus largiflorens and eucalyptus torquata were collected in spring from kashan and isfahan provinces (central region of iran). after drying the plant materials in shade, their essential oils were obtained by hydro-distillation. the oils were analyzed by capillary gas c...
