Introduction: The present study was aimed to investigate the dimensions of quality of work life and its relation to job satisfaction among workers of automotive industry. Materials and Methods: In this descriptive-analytical study, 150 workers of an automotive industry in Tehran city were chosen by simple random sampling method. Three questionnaires of demographic characteristics, quality of ...
Introduction: Previous studies have shown that various factors such as emotional stress can trigger of MI in susceptible persons. More studies are needed to evaluate the characteristics of patients regarding to emotional stress, heavy work, routine activity, infection or rest before occurrence of MI. Methods: We studied 608 consecutive hospitalized in CCUs from May 2000 to October 2001. For pa...
Urban soil may be a source of occupational exposure to various pollutants in gardening and land cultivation. This paper presents data of a one-year follow-up of lead, cadmium, nickel, chromium, and vanadium in the environment of the city of Bologna. Samples of soil and leaves were collected at three locations; gardens from the inner-city high-traffic area, parks in moderate-traffic area, and pa...
the aim of this paper is eliminating cr(vi) by natural hap. hap is a inexpensive material which is used from bovine critical bone ash in order to remove heavy metal ions like cr(vi). some experiments in different ph are performed (ph=2,3,7). maximum adsorption was appeared at ph=2, dosage=0.3 gr, c0=10 mg/l. cr(vi) removal depends on ph value and initial amount of cr(vi) result of experiments w...
This study aimed to elucidate cardiovascular loads (CVL) in construction workers during work and leisure by relative heart rate (RHR) over several days. Furthermore, we sought to evaluate the level of CVL in relation to individual factors, work ability, musculoskeletal pain and subjective general health. From a group of 255 construction workers responding to the baseline questionnaire, the CVL ...
in current work, cds/black carbon nanocomposites were successfully synthesized with the aid of chestnut and cadmium nitrate as the starting reagents. besides, the effects of preparation parameters such as reaction time, and precursor concentration on the morphology of products and removal of heavy metals (hg+2, pb+2) were studied by scanning electron microscopy images and batch adsorption mode....
Combination of local therapies with immunotherapy, to convert the individual tumor into an in situ vaccine, is currently considered one of the most promising strategies to defeat cancer. The application of local radiation therapy as an adjuvant to immunotherapy is under active investigation both preclinically and clinically. The recent work of Gameiro et al published in the Red Journal in May t...
Although the term workaholism is widely used, little consensus exists about its meaning, and there is a great need for further theoretical and methodological advancement. We attempt to address this need by introducing the concept of Heavy Work Investment (HWI), and viewing workaholism as only one of its subtypes. Furthermore, we propose a model consisting of four main components: HWI, its possi...
Nowadays, heavy mesons and baryons are produced and decayed at LHC in abundance. These processes are good sources to study the QCD theory, especially to study the hadron structures. Therefore, the phenomenology of heavy hadrons fragmentation function is a basic and important subject in the Particle Physics. In the present work, we replicate the calculation heavy meson fragmentation function in...
