The aim of this paper was to investigate the effect of aromatherapy massage using lavender oil as a possible treatment for this condition. This research was carried out on a group of 40 infants between 2 and 6 weeks of age with a gestational age of 38-42 weeks and normal development and growth. All the infants weighed between 2500 and 4000 g at birth and all exhibited the signs of colic. Infant...
Background & Aim: Achillea filipendulina is one of the most important species of the family Asteraceae and, it considered as one of the most valuable medicinal and ornamental plants. Environmental factors affected on quality and quantity of the essential oil of medicinal and aromatic plants. So, selecting of appropriate season for harvesting can lead to increase quality and quantity yi...
Sustainable agriculture can increase the efficiency of resource utilization, provide longer productivity and create a balance in the environment. A field experiment was conducted to study the use of organic and chemical fertilizers on biomass, essential oil content and essential oil yield as well as chemical compositions of Dracocephalum polychaetum Burnm in the first and second cutting. The tr...
Background and Aims: Because of the toxicity and side-effects of synthetic drugs, there is a growing interest in biomedical plants. The aim of this study was to evaluate in vitro antileishmanial activity of Carum copticum essential oil against Leishmania (L) major. Materials and Methods: Nineteen experimental groups were designed to determine the effect of Carum copticum essential oil against ...
In this research, nano materials with tubular structures are added to SAE 20W50 engine oil to study the rate of their effects on the properties of engine oil. Multi-walled carbon nanotubes (MWCNTs) and vanadium oxide nanotubes (VONTs) has been used as two different additive materials, one of them is carbonic and the other is metallic oxides and their effect on different parameters contain...
The root system of perennials is composed of the roots of different growth years. The nutrient storage capacities and activities of roots are an important basis for judging root components and plant senescence. In this research, changes in the contents of water-soluble carbohydrate (WSC) were used as indicators of the nutrient storage and activity of roots of different life years. From the earl...
two year field experiment was carried out on two early maturing varieties of soybean (glycine max (l.) men.) bred in russia. the purpose was to investigate the possibility of production and to study the effects of nitrogen supply on soybean seed yield and yield components. a range of zero to 100 kg n ha in 1995 when plants suffered from water deficiency and zero to 100 kg n ha -1 in 1996 when p...
In 1994, its second full production year, field-grown meristemmed 'Black Mitchum' peppermint performed differently than in 1993, when compared with a non-meristemmed treatment in a field trial at the OSU-COARC. The difference between years may be partly attributed to better meeting the fertility and soil moisture needs of meristemmed plants in 1994. Plants were not moisture-stressed near harves...
To define plant 'nutritional quality' for aphids, the causal basis of the variation in aphid performance between host plants of different developmental ages was explored using the aphids Myzus persicae and Macrosiphum euphorbiae on potato plants (Solanum tuberosum). Both aphid species performed better on developmentally young ('pre-tuber-filling') plants than on mature ('tuber-filling') plants....
The effects of the encapsulation of Satureja bachtiarica essential oil with chitosan on the shelf life and quality of pomegranate seeds were studied in an experiment based on a completely randomized design with eight treatments, including different ratios of chitosan to S. bachtiarica essential oil (control, 1:1–0.3, 1:1–0.6, 1:2–0.3, 1:2–0.6, 1:3–0.3, 1:3–0.6) and three replications. The resul...
