Stem/branch maintenance respiration for a stand of Japanese red pine (Pinus densiflora) during the dormant season was examined using an open flow system. The stem/branch respiration rates per unit of volume were closely related to the thickness of the stems and branches, e.g. it decreased with increasing diameter (p<0.0001). When the respiration rates on the various positions were regressed aga...

Salicornia is a valuable halophyte annual plant in the most species. This salinity tolerance plant that grows in salt water marshes are found all over the world. Since salinity is a major stress factor, Salicornia is a priceless edible vegetable, considered to be a favourable resource for cultivation in arid and semiarid coastal zones. However, the important thing is ...

Respiration rate and gas exchange through the package material are the processes involved in creating a modified atmosphere inside a package that will extend shelf life of fresh fruits and vegetables. Thus, modelling respiration rate of the selected produce is crucial to the design of a successful modified atmosphere packaging (MAP) system. In this paper, general aspects of the respiration proc...

background: various strategies have been suggested for the treatment of respiratory distress syndrome (rds). objectives: the aim of this study was to compare the efficacies of two common methods of rds management among neonates with low birth weight. patients and methods: a cohort study was conducted on 98 neonates with definite diagnosis of rds during 2008-2009. the neonates were divided into ...

background: workers in wastewater treatment plants are exposed to a wide range of chemicals as well as biological contaminants. objective: to ascertain whether exposure to bio-aerosols under the normal working conditions in wastewater treatment plants is associated with any significant changes in the prevalence of respiratory symptoms and lung function capacities. methods: 198 employees of wast...

patients and methods a cross-sectional study was conducted at icus of imam-reza and vali-asr hospitals, birjand, iran. sampling was done through a census in which 53 icu nurses participated. descriptive statistics, kolmogorov-smirnov test, mann-whitney u tests and kendall's correlation coefficient were used to analyze the data. results a total of 53 nurses participated in this study. most of th...

The measurement of respiration is very important because it provides a window through which we can determine the metabolic activity of plant tissues. During aerobic respiration, stored food (e.g., carbohydrates, fats, proteins) are combined with oxygen from the atmosphere to produce carbon dioxide, water and the energy needed to maintain the plant cell, tissue and quality of the commodity. The ...
