85 fungi in outdoor air in the present study is reported. Over 44 taxa of anamorphic fungal spores were observed. The results of this study will contribute with information about existing mycoflora in atmosphere since knowing the local aeroallergens facilitates the diagnosis and treatment.
Herbal medicine is the oldest and still the most widely used system of medicine in the world today and they are made exclusively from plants. However, most of these medicines or drugs are adulterated due to lack of proper identification of the plant samples. Method of checking adulteration of drug plants is the main focus of this study. The identification and authentication of...

Field experiment was conducted at the field of Agriculture College, Al-Qasim Green University at the agricultural season 2014/2015 to study the effect of two soil fertilizers (compound 18-18-18- at the rate of 200 kg.ha-1and sheep manure as organic fertilizer at the rate of 10 tons.ha-1) as well as control, and their interaction with foliar fertilizer of sea weed extract and urea...
The paper presents a research model of leaf investigation, based on biometrical measurements and morphological observations. In literature, there are only few studies concerning the biometrical investigation and analysis applied on spontaneous and cultivar plants leaves. The article comprises biometrical investigations on a culture hybrid Populus×canadensis Moench leaves. The...
A qualitative and quantitative evaluation of pollen fall in the atmosphere of Tavşanlı (Kütahya) is presented in this study. A continuous aerobiological survey of the atmosphere of Tavşanlı was carried out from beginning of January 2003 to end of December 2004 by means of the gravimetric method using Durham apparatus. Weekly pollen grains in per cm2 were calculated. During two...
The present investigation was carried out at Department of Genetics and Plant Breeding, Sam Higginbottom Institute of Agriculture, Technology & Sciences (SHIATS), Allahabad, Uttar Pradesh during kharif 2014. The experimental material consisted of 11 Groundnut genotypes along with one check (IND-156). The genotypes were sown at Field Experimentation Centre in three replications...
In order to investigate the effects of micronutrients on quantitative and qualitative yield traits of sugar beet, an experiment was performed during growing season of 2013-2014in the Esfarayen region, located in the North-East of Iran. Treatments consisted of three levels of mixture of micronutrients (spraying with 0, 1, 2 L ha-1) and the number of applications (once 45 days...
Turmeric and ginger are spices derived from the rhizomes of Curcuma longa and Zingiber officinale respectively. The rhizomes of C. longa and Z. officinale were extracted in hexane, ethyl acetate, methanol and water. Phytochemical screening was carried out on each of the extracts. Proximate analysis to determine the extractive values, moisture content, total ash, crude fibre, acid...
The most important issue which has attracted the attention of many scientists is the climate change and global warming due to greenhouse gas emission which has caused the world faced with a great human and environmental disaster. In this study, the amount of greenhouse gas (GHG) emissions was estimated in the semi-traditional and semi-mechanized rice production systems in Dargaz...
The hippocampus and the amygdala are structures of mammalian brain both involved in memorizing. However, they are responsible for different types of memory: the hippocampus is involved in creating and storing declarative engrams and the amygdala is engaged in some of non-declarative learning. During memorization, changes of synapses appear and it is believed that they encode...
In urban conditions, we investigated several leaf traits (leaf area, specific leaf area, fractal dimension and specific leaf weight) on Taraxacum officinale, Tilia tomentosa, Aesculus hippocastanum and Ambrosia artemisiifolia. The analyzed organs were mature leaves, on the first indications of senescence. This study used an exact, inexpensive and efficient in terms of costs...
