The Influence of Meteorological Parameters on Indoor and Outdoor Radon Concentrations: A Preliminary Case Study
In this study the influence of meteorology on indoor and outdoor radon concentrations in four different locations in a Mediterranean country have been studied. Indoor, daily radon concentrations were generally higher (0.2 – 85.0 Bq m-3) than outdoor daily concentrations (0.8 – 3.6 Bq m-3) in all locations studied with the exception of one that was built on pylons, thus reducing infiltration of radon from the ground. Indoor and outdoor meteorological parameters influence both the indoor and outdoor radon concentrations. In particular, outdoor wind speed and relative humidity show a negative correlation with both outdoor and indoor concentrations at all locations. Radon concentrations were also measured at two different levels of a terraced house (a common household type in Malta), in the basement and on ground floor.
A Preliminary Evaluation Study to Determine the Effectiveness of Infra-Red Photography for the Rapid Visualisation of Gun Shot Residue on Fabric
Infrared (IR) photography has been shown to be a proficient technique for the examination of documents, blood traces and ageing of skin injuries. However, its application in relation to the visualisation of latent Gunshot Residue (GSR) deposits has, until now, been significantly under researched. This paper evaluates the effectiveness of IR photography as a rapid technique for GSR visualisation on different fabric types.
The link between disease and the oral cavity represent clinically important factors that have given rise to the interest in using saliva as a diagnostic fluid for systemic diseases. The objective of this study was to detect and quantify cancer related cytokines in the saliva of women with breast cancer and compare their concentrations to a healthy cohort.
Preliminary Investigation of the Interaction of Misoprostol and Phenylbutazone on Bone Response to Injury in Horses
Phenylbutazone (PBZ) is commonly used in equine patients for treatment of orthopedic injuries. Phenylbutazone may adversely affect bone healing because of suppression of prostaglandin production. We hypothesized that administration of the prostaglandin analog misoprostol would enhance bone healing and mitigate the untoward effects of PBZ on bone response to injury in horses. The objectives of this study were to determine whether the administration of misoprostol would enhance bone healing and whether concurrent administration of PBZ and misoprostol would mitigate the untoward effects of phenylbutazone. Twenty horses were randomly assigned to one of four groups (n=5 per group): Group 1 (untreated control), Group 2 (phenylbutazone alone), Group 3 (misoprostol, alone), or Group 4 (concurrent treatment with phenylbutazone and misoprostol). A 4.5-mm diameter uni-cortical bone defect was created in one metacarpal III bone of all horses. Fluorochromic bone labels were administered intravenously on Days 0, 7, and 14. Computed tomographic osteoabsorptiometry and histomorphometric analyses were performed on the harvested metacarpal bones. Phenylbutazone treatment caused a decrease in endosteal new bone formation. Administration of misoprostol appeared to mitigate the magnitude of the PBZ effect on new bone formation (endosteal in-growth, p<0.06). Bone specific alkaline phosphatase serum activity decreased throughout the 14-day period of stall confinement. Mineral apposition rates increased in all groups during the period from 7 to 14 days after bone injury. Further research is needed to determine if this effect is significant. The administration of misoprostol may be beneficial to lessen the undesired impact of phenylbutazone on bone healing in horses.
The objective of this study was to study ear biometric for identification purpose among young adults in Malaysia. A total of 148 subjects (74 males and 74 females) ranging in age from 18 to 25 years were taken from Campus Kuala Lumpur of National University of Malaysia (UKMKKL). A total of twelve biometrics based on Iannarelli’s method as well as ear length and ear width were used as measurements. Statistical analysis indicated that left and right ears had no significant difference (p > 0.05). Gender difference was found to be highly significant for nine out of fourteen ear biometrics (p < 0.05). However, there were only five out of fourteen ear biometrics had significant difference between Chinese and Malays (p < 0.05). Statistical analysis had also indicated that differences among ages for each ear biometrics were insignificant and no clear correlation between ear biometrics and ages was obtained (p > 0.05). Formulae for gender and race estimation were obtained by using Classification and Regression (C & R) Tree. Formulae of ear length had the highest accuracy (78.7%) for gender estimation.
Like a drug for a purpose of treating or preventing a disease, a health food has to be scientifically evaluation and officially approved before it legally is marketed in China.
Predictors of Stress Fracture Susceptibility in Arab Female Military Recruits during Combat Training: A Preliminary Study
Military recruits and athletes regularly engaging in vigorous physical activities are at increased risk for sustaining lower limb overuse injuries.
A Laparoscopic Assisted Minilaparotomy Hysterectomy approach for Very Large Fibroid Uteri of more than 1000 grams – A Preliminary Study
Minilaparotomy has been used for tubal sterilization for decades. It became a new surgical idea described by some who performed minilaparotomy hysterectomy and achieved outcomes that were less invasive than those of traditional open laparotomy. Pelosi and Pelosi 2004 reported a minilaparotomy procedure in patients in whom vaginal hysterectomy was considered contraindicated. Their procedure offered a safe alternative with minimal access and good outcome.
Scientists began developing and publishing a series of best practices to mitigate laboratory risks in the 1970’s. These biosafety guidelines are disseminated by the Department of Health and Human Services in the publication Biosafety in Microbiological and Biomedical Laboratories (BMBL).
Synthesis of BaTiO3 Nanowires via Anodic Aluminum Oxide Template Method Assisted by Vacuum-and-Drop Loading
In this paper, we report on the synthesis of BaTiO3 nanowires via the anodic aluminum oxide template method. To fill in the precursors of BaTiO3 into anodic aluminum oxide templates, the vacuum and drop loading method developed in our previous study was used. Ba(CH3COO)2 (barium acetate) and C12H28O4Ti (tetraisopropyl orthotitanate) were used as Ba and Ti sources, respectively. Anodic aluminum oxide membranes with the through-hole diameter of ~200 nm were used as the template for BaTiO3 nanowires.
