Safety climate in construction industry the case of Gaza strip

The construction industry plays an important role in the social and economic development in Palestine. Safety in the construction industry is considered a major issue in developed and developing countries. Palestine's construction suffers recently from poor safety and health conditions as safety rules do not exists and work hazards at the workplace are not perceived. The main objective of this paper is to investigate the perceptions of construction workers regarding safey climate and safety behavior work in Gaza Strip construction sites. It will also explore the relationship between personal characteristics of constuction workers and safety climate/safe work behavior. Furthermore, the relationship between safety climate and safe work behavior will be explored. The methodology adopted in this paper was based on comprehensive questionnaire targeting the construction workers. 300 questionnaires were distributed and 246 questionnaires were collected and then analyzed to achieve the research objectives. It was found that construction workers have positive attitude and perception towards safety climate and safe work behavior. There exist a positive relationship between safety climate and safe work behavior. There is an impact of experience, field of work, smoking habit, and job on safety climate. In contrast, the personal characteristics; marital status, direct employer, educational level, family members to support, skill levels have no influence on safety climate. There exist a relationship between personal characteristics age, experience, field of work, smoking habit, educational level, and job on the field safe work behavior. On the other hand no impact

Remote sensing assessment of Jabi Lake and its environs: A developmental perspective

This paper is aimed at examining the relevance and impact of Jabi Lake in urban development and sustainable environmental change management. It uses a 2km radius buffer of remotely sensed satellite data from Landsat to examine the landuse/land cover dynamics within Jabi Lake and its environs in FCT-Abuja, Nigeria. Using maximum likelihood algorithm in ERDAS Imagine software, the supervised classification result shows that the lake water body decreased from 4.1 % in 1987 to 3.1% in 2006 and later increased to 4.0% in 2014. Built up experienced the highest landuse/land cover change from 3.17% in 1987 to 33.4% in 2006 and 37.5% in 2014. Light and dense vegetation reduced the most, while bare surface also showed an increase due to rapid urban development around the lake in the last 27 years. The focused group discussion (FGD) reveals that the conversion of previous agricultural land use and unplanned land uses to residential land use was due to high demand for residential housing around the lake. The perceived ambience scenery and accessible good road network were ranked as the first and second major positive centripetal forces of attraction to building near the lake while expensive land purchase and high rent were ranked first and second as the most negative centrifugal impacts of the lake on the environment. In conclusion, there is the need to monitor the progression of urban development so as to safeguard the lake for aquatic agriculture and it’s immediate environment from further deterioration

Hepatoprotective effect of Balanites aegyptiaca (L.) Delile leaves against carbon tetrachloride-induced hepatic damage in rats

Methanolic extract of Balanites aegyptiaca (L.) Delile (leaves), was evaluated for its hepatoprotective activity against carbon tetrachloride (CCl4)-induced hepatic damage in Wistar rats; by measuring levels of serum marker enzymes like serum glutamate oxaloacetate transaminase (SGOT), serum glutamate pyruvate transaminase (SGPT), alkaline phosphatase (ALP) and total bilirubin. Histological studies were also carried out to support our hypothesis. Administration of the extract (200 and 400 mg/kg) orally markedly prevented CCl4-induced elevation of serum GPT, GOT, ALP and total bilirubin levels. A comparative histopathological study of liver in treated groups exhibited similarity to normal tissue architecture, compared to CCl4-treated group

Characteristics and Chemical Composition of the Seeds

Abstract: A field experiments were carried out at Shambat, Sudan (Latitude 15 40´ N and o Longitude 32 32´ E) in three consecutive seasons (2000/03) to investigate the effect of o Bradyrhizobium inoculation, chicken manure or sulphur fertilization on physical characteristics and chemical composition of hyacinth bean (Dolichos hyacinth L.) seeds. The results showed that chicken manure or sulphur fertilization in the presence or absence of Bradyrhizobium inoculation and their interactions significantly (P # 0.05) improved hydration coefficient and cookability of the seeds. Moisture and ash contents were not greatly affected while fat, fiber, protein and carbohydrates were greatly affected especially when 10 t/fed chicken manure or 100 kg/fed sulphur were applied with or without inoculation. Moreover, inoculation with or without chicken manure or sulphur fertilization greatly affected the chemical composition of the seeds. Tannin content of the seeds was increased by application of fertilizers especially when accompanied by inoculation. However, the in vitro protein digestibility was significantly (P # 0.05) improved especially when chicken manure or sulphur was applied to inoculated seeds. The results indicated that all measured parameters increased with increasing level of amendments (manure or sulphur) and the highest value of each parameter was observed with either 10 t/fed chicken manure or 100 kg/fed sulfur

Utilization of jojoba oil and salicylic acid as postharvest treatment on storability and fruit quality of ‘Late Swelling’ peach cultivar

The ‘Late-Swelling’ peach is an important cultivar due to its attributes of fruit quality, such as handling ability and late harvest season. Peaches rapidly deteriorate during storage, which shortens their shelf-life. The preservation of quality traits of ‘Late-Swelling’ peach during handling and storage investigated. Fruits harvested in the early ripe stage (last week of June) were either dipped in jojoba oil (JO) 500, 1000, and 1500 ppm and salicylic acid (SA) 100, 200, and 300 ppm, then stored at 5+1 °C and 85% RH for 35 days besides 7 days as shelf-life the fruits were examined every 7 days until the end of the experiment. Positive influences were observed for JO and SA on the different chemical and physical characteristics of the peach fruits under study especially those related to storability and fruit quality. All fruits treated with JO 1500 and 1000 ppm, and SA 300 ppm maintained the fruit firmness, hº, total acidity, and ascorbic acid over the whole storage period, in addition to the lowest decay and weight loss, as well as maintaining the fruit sensory quality and decreased peroxidase [PPO] activity while increasing polyphenol oxidase [POD], catalase [CAT], and ascorbate peroxidase [APX] activities compared with the control at the end of shelf-life period. In conclusion, our results suggest using JO and SA to enhance and prolong the storability of peach fruits at 5+1 °C and 85% RH

The prehistory of Jebel Moya, Sudan: results from the first three seasons of excavations

This paper outlines the ways in which the project is addressing the colonial legacy of Henry Wellcome as well as presenting the data from the first three field seasons at Jebel Moya, south-central Sudan. These data have substantially revised our chronological and socio-economic understanding of the site. Our excavations, initiated in 2017 and continued in 2019 and 2022, show a longer, more continuous occupation of the site than has been previously recognised. The faunal and botanical remains have implications for the spread of early domesticates in the eastern Sahel and for climate changes, and raise issues of resilience. There is confirmed human burial activity from at least the third millennium BC onwards, while the pottery continues to yield information about the variety of decoration and, for the final Assemblage 3, data on its usage. Overall, the continued importance of the site for the eastern Sahel is re-emphasised

Medical services at the FIFA world cup Qatar 2022

Objective The Football World Cup is among the biggest sporting events in the world, but data to inform the requirements of medical care for such tournaments are limited. This study describes the athlete and team medical services at the FIFA World Cup Qatar 2022. Methods Three different medical service entities were identified through a needs analysis based on expert advice, team physician interviews and questionnaires prior to the event: 'Team Services' to provide any workforce or equipment needs of the teams, a 'Polyclinic' to manage any acute medical demands, and a 'recovery centre' to improve game readiness throughout the tournament. All services had been set up prior to the tournament and thoroughly tested. Results Of a total of 832 athletes, ∼1300 team delegation and ∼130 match officials, 167 individuals including 129 (77%) athletes and 38 (23%) non-athletes were assessed in the polyclinic. For the 129 athletes (median 4 players per team), medical imaging was the most requested service, which peaked during the group phase of the tournament. Most requests were received during normal working hours despite many games finishing late at night. 30 of the 32 participating teams solicited medical services for their players at least once. Three teams made use of the recovery facilities, and 17 teams requested additional medical equipment or clinical assistance. Conclusion Central imaging services was the most used medical resource at the FIFA World Cup Qatar 2022, and over half of teams required additional medical equipment or personnel. These data may inform planning of medical services for similar events in the future

Effect of inhibition of estrogen synthesis or blocking its receptors on male rabbit reproduction

Purpose: The present aimed to study the effects of tamoxifen and fadrozole on semen characteristics and fertility, besides we emphasized the relationship between brain estrogen and sexual behavior in male rabbits. Methods: Eighty rabbits allocated into four equal groups. The control injected with sesame oil; the second injected with estradiol; the third injected with tamoxifen and the fourth injected with fadrozole. Treatments done daily for 60 days. Ten rabbits from each group served artificial vagina for evaluation of semen and sexual behavior. The other ten served female rabbits for fertility test. Reproductive organ and brain weights recorded. Serum and testicular testosterone, serum and brain estradiol and testicular zinc and cholesterol levels assayed. Results: Tamoxifen caused decrease in all estimated parameters except it increased both sperm ab normalities percentage; testicular cholesterol content; time of reaction and time between two consecutive ejaculations. Fadrozole results were opposite to that of tamoxifen except it increased the time between two consecutive ejaculations and decreased brain estradiol level. Conclusion: Fadrozole may be improve male rabbits performance along with elevated testosterone evident highlighting the important played by testosterone in regulating male rabbit fertility and advocacy the postulate that testosterone effect is mediated in part by its aromatization to estradiol
