Three Indian freshwater teleostean fishes Anabas testudineus, Heteropneustes fossilis and Oreochromis niloticus were exposed to almix (66.67 mg/l) under laboratory condition for a period of 30 days to investigate the activity of transaminases (alanine aminotransferase (ALT), aspartate aminotransferase (AST)), and phosphatase (alkaline phosphatase (ALP)) in the gill, intestine, heart and muscle tissues. ALT levels showed significant elevation (p H. fossilis > A. testudineus. Therefore, assessment of these metabolic enzymes in tissue systems is important for evaluation of the herbicidal contamination like almix on fish species.
在实验室条件下,将3种印度淡水硬骨鱼Anabas testudineus、Heteropneustes fossilis和Oreochromis niloticus分别暴露于浓度为66.67 mg/l的almix环境中30 d,研究其鳃、肠、心脏和肌肉组织中转氨酶(谷丙转氨酶(ALT)、天冬氨酸转氨酶(AST)和磷酸酶(碱性磷酸酶(ALP))的活性。ALT水平显著升高(p H. fossil > A. testudineus)。因此,评价这些代谢酶在组织系统中的作用对评价白矾等除草剂对鱼类的污染具有重要意义。

The present study aims to provide information about the management, segregation, storage and disposal of medical wastes in public as well as private hospitals in Gaza Strip-Palestine. A cross sectional study was employed and simple random sampling technique were used to distribute a semi structured questionnaire among 164 health workers at two hospitals in Gaza Strip with 100 respondents from governmental hospital and 64 respondents from private hospital. The results disclosed that, healthcare facilities whether private and governmental hospitals still suffer from inappropriate biomedical wastes management which have not received sufficient concern according to 60% of participants who pointed out that hazardous and medical wastes are still handled and disposed together with domestic wastes and segregation was applied only for sharp waste which is collected in special sharp boxes at the beginning after usage. Furthermore, around 47% of respondents don't know where medical storage place is, and don't know if there is mark to show place of storage. Besides, 42% of respondents don't know if it's there mean for transferring medical waste, and 43% don't know its type or if it's available always. In the surveyed hospitals, there is deficiency in implementing training courses about healthcare waste management as 23% only of all study subjects had been provided with training on how to deal with medical waste. Therefore, the Ministry of Health and healthcare institutions should give more consideration towards policies for the proper management and disposal of health care wastes in order to develop medical waste management practices in Palestine.
本研究的目的是提供有关加沙地带-巴勒斯坦公立和私立医院医疗废物的管理、隔离、储存和处置的信息。采用了横断面研究和简单随机抽样技术,在加沙地带两家医院的164名卫生工作者中分发了半结构化问卷,其中100名答复者来自政府医院,64名答复者来自私立医院。结果显示,医疗设施,无论是私立医院还是政府医院,仍然存在不适当的生物医学废物管理问题,这一点没有得到60%的与会者的充分关注,他们指出,危险废物和医疗废物仍然与生活废物一起处理和处置,只对尖锐废物实行隔离,这些废物在使用后一开始就收集在特殊的尖锐盒子里。此外,约47%的受访者不知道医疗储存地点在哪里,也不知道是否有显示储存地点的标志。此外,42%的受访者不知道它是否有转移医疗废物的手段,43%的受访者不知道它的类型或是否总是可用。在接受调查的医院中,在实施医疗废物管理培训课程方面存在不足,因为只有23%的研究对象接受了如何处理医疗废物的培训。因此,卫生部和卫生保健机构应更多地考虑适当管理和处置卫生保健废物的政策,以便在巴勒斯坦发展医疗废物管理做法。

The study dealt with the concentration of air pollutants emitted from Kushtia sugar mills in Jagati region of Bangladesh in order to evaluate their impact on human health. The dispersion of air pollutants from sugar mill's chimney was obtained through point source Gaussian dispersion model. The air pollutants were monitored during winter season in 2011- 2012. A questionnaire survey was randomly carried out in a small scale at the study area. The result showed that the maximum concentration of SO2, NOx and PM10 were 28.837 µg/m 3 , 76.177 µg/m 3 and 380.339 µg/m 3 respectively. The particulate matter (PM10) concentration was found to be very high whereas sulfur dioxide (SO2) and nitrogen oxide (NOx) concentrations were low at the study area. The calculated value of air pollution index (API) was 88.18 which indicate that heavy air pollution can predispose individuals to heart and lung disease in the study area people. This study revealed that the concentration of particulate matter found in Kushtia sugar mill had exceeded the minimum level according to the WHO standards. The high concentration of PM10 is suggested to affect human health and environmental conditions in the study area.
该研究涉及孟加拉国贾加蒂地区库什蒂亚糖厂排放的空气污染物浓度,以评估其对人类健康的影响。采用点源高斯色散模型,对制糖厂烟囱空气污染物的色散进行了数值模拟。对2011- 2012年冬季大气污染物进行了监测。在研究区随机进行小范围问卷调查。结果表明:SO2、NOx和PM10的最大浓度分别为28.837µg/m 3、76.177µg/m 3和380.339µg/m 3;研究区域的颗粒物(PM10)浓度很高,而二氧化硫(SO2)和氮氧化物(NOx)浓度很低。空气污染指数(API)计算值为88.18,表明重度空气污染可使研究区人群易患心肺疾病。该研究表明,库什蒂亚糖厂发现的颗粒物浓度超过了世界卫生组织标准的最低水平。高浓度的PM10对研究区内的人体健康和环境状况造成影响。

Phytoremediation technology is using plants to clean up contaminated sites is a promising loom to restore the environment and ecosystem. Pollution of the environment with toxic organic and heavy metal pollutants is one of major problem facing developed and developing nations today. Heavy metals restrain biodegradation of chlorinated organics by interacting with enzymes directly concerned in biodegradation or those involved in common metabolism. Prophecy of heavy metal toxicity effects on organic pollutant biodegradation in co-contaminated soil is tricky since heavy metals may be present in a variety of chemical and physical forms. Even if much remains to be studied, phytoremediation will clearly play some role in the stabilization and remediation of many contaminated sites. The main factor driving the execution of phytoremediation projects are low costs with considerable improvements in site aesthetics and the potential for ecosystem restoration. In this review, the potential and various aspects of few Brassicaceae (Mustard family) members in phytoremediation have been discussed due to their well known natural tolerant against various environmental stresses including heavy metals.
植物修复技术是利用植物修复污染场地,恢复环境和生态系统的一种很有前景的技术。有毒有机和重金属污染物污染环境是当今发达国家和发展中国家面临的主要问题之一。重金属通过与直接参与生物降解或参与普通代谢的酶相互作用来抑制氯化有机物的生物降解。由于重金属可能以多种化学和物理形式存在,因此预测重金属对共污染土壤中有机污染物生物降解的毒性作用是很棘手的。尽管还有许多有待研究的地方,但植物修复显然将在许多污染场地的稳定和修复中发挥一定作用。推动植物修复项目实施的主要因素是成本低、场地美学显著改善和生态系统恢复潜力。本文综述了几种芸苔科(芥菜科)植物对包括重金属在内的各种环境胁迫的天然耐受性,并对其在植物修复方面的潜力进行了综述。

Fruit flies (Diptera: Tephritidae) are amongst the world's worst pests of fruits that cause enormous losses in orchards. Due to their economic importance, fruit flies are severe pests of Mango Mangifera indica L. fruit, and their monitoring and infestation estimation are essential in order to formulate integrated pest management program. For practical field implementation, two variables such as flies per trap per weak were monitored by installation of Steiner traps hung on tree baited with Methyl eugenol attractant and percent fruit infestation through fruit host samplings. Surveillance for flies per trap was done each week by counting trap catches, recording and removing any flies that have been collected in traps and identifying the species. The percentage of fly infestation for mango fruit was examined by randomly analyzing a total of 100 fruits and observing number of fruits showing fruit fly oviposition or injury marks. The results showed that tephritid fruit fly Bactrocera zonata (Saunders) was the predominant species (more frequent and constant) at experimental site. Surveillance of fruit fly populations in mango orchard revealed that peak population of B. zonata (40-30 per trap per week) and fruit infestation (9.05-7.45%) were recorded in June, July and August. The availability of host fruit and its productivity were critical factors affecting population fluctuations of the B. zonata fly. All of this information gives fruit fly activity in an area, an estimate of the population, species composition, sex, growth stage and determining whether the number of pests are increasing or decreasing to decide implementation of pest control operation. Mango (Mangifera indica L.), is one of the most versatile and delicious tropical fruits, and having an outstanding flavor with a range of varieties as a member of the family Anacardiaceae. Mango has a good nutritional value and there is great variation in the form, size, color and quality of the fruits. Mango is an excellent source of vitamin A and C, as well as a good source of potassium, beta-carotene and fiber. Normally, it is produced for human consumption as raw or ripe mango products. During the processing of ripe mango, its peel and seed are generated as waste, which is approximately 40-50% of the total fruit weight. Mango peel is a good source of dietary fiber and its chemical composition may be comparable to that of citrus fiber. The peel has a high value of antioxidant activity and glucose retardation index, while its aroma and flavor are pleasant (Larrauri et al., 1999). Mango canning by-products (seed and peel) together with ensiled mango peel were subjected to
果蝇(双翅目:蝗科)是世界上最严重的水果害虫之一,给果园造成巨大损失。果蝇是芒果果实的严重害虫,具有重要的经济价值,其监测和危害评估是制定综合治理方案的基础。在实际的田间实施中,通过在树上安装施泰纳诱捕器,用甲基丁香酚引诱剂引诱,监测每个陷阱每个弱者的苍蝇数,并通过水果寄主取样监测果实侵染率。每周对每个捕蝇器的蝇类进行监测,方法是计算捕蝇器的捕获量,记录并清除捕蝇器中收集到的蝇类,并确定其种类。通过对100个芒果果实进行随机分析,观察有果蝇产卵或伤痕的芒果果实的数量,研究了芒果果实受蝇害的比例。结果表明,小绒小实蝇(Bactrocera zonata, Saunders)是试验点的优势蝇种,出现频率高,持续时间长。芒果果园蝇类监测结果显示,6月、7月和8月蝇类数量高峰(40 ~ 30只/周),果害高峰(9.05 ~ 7.45%);寄主果实的可得性及其产量是影响绿腹小蠹种群波动的关键因素。所有这些信息提供了果蝇在一个地区的活动,估计种群,种类组成,性别,生长阶段和确定害虫数量是增加还是减少,以决定实施害虫防治行动。芒果(Mangifera indica L.)是最通用和美味的热带水果之一,作为阿纳卡科的一员,品种繁多,风味突出。芒果具有很好的营养价值,果实的形状、大小、颜色和质量变化很大。芒果是维生素A和C的极好来源,也是钾、胡萝卜素和纤维的良好来源。通常,它是作为生的或成熟的芒果产品生产供人类食用的。在成熟芒果的加工过程中,其果皮和种子作为废物产生,约占果实总重量的40-50%。芒果皮是膳食纤维的良好来源,其化学成分可能与柑橘纤维相当。果皮具有较高的抗氧化活性和葡萄糖阻滞指数,香气和风味宜人(Larrauri et al., 1999)。芒果罐头副产品(种子和果皮)与青贮芒果皮一起进行了研究

The most essential effect of grazing is soil compaction due to animal traffic. The study was conducted to investigate the role of cattle grazing in soil degradation resulting from compaction using infiltration parameters at the Beef and Dairy Cattle Research Station of the Department of Animal Science of the Faculty of Agriculture, KNUST. Two fields, ungrazed and grazed (with a stocking rate of 120 cattle for three weeks) were used for the study. Physical properties such as soil texture, moisture content, bulk density, total porosity and aeration were determined. Field infiltration studies from which sorptivity (S) and steady state infiltrability (Ko) were determined were conducted with a double ring infiltrometer for one hour to determine the cumulative infiltration amount (I). The time-to-incipient ponding or runoff initiation time (tp) was calculated from the S and Ko values. Mean values of I were 1490 mm and 500 mm; S 2.72 mm/s 1/2 and 1.030 mm/s 1/2 ; Ko, 0.060 mm/s and 0.0080 mm/s for the ungrazed and grazed fields, respectively. The tp at a rainfall rate of 5 mm/h was recorded as 79.00 s on the grazed field and 419.00 s for the ungrazed field. It was observed that rainfall rates in excess of 10 mm/h would cause instantaneous ponding and/or runoff on both fields. Grazing by cattle was, thus, established to be deleterious to soil structure and infiltration due to soil compaction. Overall, infiltration parameters were found to be very useful tools for the evaluation of soil degradation due to compaction.
放牧最重要的影响是由于动物的交通造成的土壤压实。本研究在国立农业大学农学院动物科学系肉牛与奶牛研究站,利用入渗参数,探讨放牧对土壤压实退化的影响。研究使用了未放牧和放牧的两块田地(放养率为120头牛,持续3周)。测定了土壤的物理性质,如质地、含水量、容重、总孔隙度和通气性。利用双环渗透计进行了现场入渗研究,测定了1小时的吸附率(S)和稳态渗透性(Ko),以确定累积入渗量(I)。根据S和Ko值计算了初始积水时间或径流启动时间(tp)。I的平均值为1490 mm和500 mm;S 2.72 mm/ S 1/2和1.030 mm/ S 1/2;Ko为0.060 mm/s,放牧地为0.0080 mm/s。在降雨速率为5 mm/h时,放牧地的tp为79.00 s,未放牧地的tp为419.00 s。据观察,如果降雨量超过每小时10毫米,就会在这两块土地上造成瞬时积水和/或径流。因此,由于土壤压实,牛放牧对土壤结构和渗透是有害的。总的来说,入渗参数被认为是评估土壤因压实而退化的非常有用的工具。

The color of anthocyanins is unstable and quickly decolourized by reactions. Thus anthocyanins in living cells may have mechanisms for resistance to maintain color stability. Copigmentation is the main color – stabilizing mechanism. In this study copigmentation of anthocyanin in Seedless Red grape were investigated with catechin copigment. The dependence of the copigmentation process on the heating, UV and copigment concentration was studied. Five levels of copigment concentrations as: 0, 120, 240, 480, 960 (mg/l) were examined. The copigmentation effects increased with copigment contain. During UV irradiation, anthocyanin-copigmentation complex showed higher stability in comparison with anthocyanins. Also UV irradiation has the biggest effect on the copigmentation complex in comparision with heating. Keyword: Anthocyanin, Catechin, Copigment, Heating, Seedless Red
花青素的颜色不稳定,可通过反应迅速脱色。因此,活细胞中的花青素可能具有抵抗维持颜色稳定性的机制。色素合成是主要的稳色机制。研究了无核红葡萄花青素与儿茶素的共色素作用。研究了复合色素的合成过程与加热、紫外线和浓度的关系。测定了色素浓度0、120、240、480、960 (mg/l) 5个水平。随着色素含量的增加,其着色效果增强。在紫外线照射下,花青素-共色素复合物表现出比花青素更高的稳定性。与加热相比,紫外线照射对色素复合物的影响最大。关键词:花青素,儿茶素,色素,加热,无籽红

The characterization of landfill leachate has been well established. However, its biodegradation properties have not been well reported. Therefore, this research was undertaken to investigate the biodegradability of semi-aerobic sanitary landfill and the ratio of the biological oxygen demand (BOD) to chemical oxygen demand (COD) BOD5/COD, COD fraction on leachate from Pulau Burung landfill Site (PBLS). These parameters are important as they may provide appropriate and suitable treatment for this kind of leachate. In this research, leachate from two different ponds were studied i.e., the raw leachate from leachate collection pond and the leachate effluents of the treatment plant'. Five different measurement points were tested for each pond to understand the characterization for leachate. The soluble and particulate organic compound was separated by filtration using a 0.45μm pore size membrane filter. The results indicated that leachate in PBLS has low BOD5/COD ratio. The total COD (TCOD) ranged from 2040mg/L to 3160mg/L. The Biodegradable COD (BCOD), unbiodegradable COD (UBOD), soluble biodegradable (RBCOD), particlulate biodegradable (SBCOD), particulate inert (UPCOD), and soluble inert (USCOD) ranged from 53%-67%, 33%-47%, 38%-46%, 9%-25%, 12%-26%, and 18%-25%. This indicates, the leachate in Pulau Burung Landfill Site have different of COD fraction behavior compare with domestic wastewater. In which, leachate have low SBCOD, but relatively high in others COD fraction compare with domestic wastewater.
垃圾渗滤液的特性已经得到了很好的确定。然而,其生物降解性能尚未得到很好的报道。为此,本研究旨在研究半好氧卫生填埋场的生物降解性,以及布隆岛垃圾填埋场渗滤液中生物需氧量(BOD)与化学需氧量(COD)的比值、BOD5/COD、COD分数。这些参数很重要,因为它们可以为这类渗滤液提供适当和合适的处理方法。在本研究中,研究了两个不同池的渗滤液,即来自渗滤液收集池的原渗滤液和处理厂的渗滤液。每个池塘测试了五个不同的测量点,以了解渗滤液的特征。采用孔径0.45μm的膜过滤器过滤可溶性有机化合物和颗粒性有机化合物。结果表明,PBLS渗滤液的BOD5/COD比较低。总COD (TCOD)为2040mg/L ~ 3160mg/L。可生物降解COD (BCOD)、不可生物降解COD (UBOD)、可溶性生物降解COD (RBCOD)、颗粒生物降解COD (SBCOD)、颗粒惰性COD (UPCOD)和可溶性惰性COD (USCOD)的范围分别为53% ~ 67%、33% ~ 47%、38% ~ 46%、9% ~ 25%、12% ~ 26%和18% ~ 25%。这表明,埔隆岛垃圾填埋场的渗滤液与生活污水相比,其COD组分的行为有所不同。其中,渗滤液的SBCOD较低,其他COD分数相对生活污水较高。

Acquired immune deficiency syndrome (AIDS) is a kind of disease related to immune system caused by HIV virus. Up to now many medicinal compositions have been using for treatment of this disease both in In vivo and In vitro conditions. Caffeic Acid Phenethyl Ester (CAPE) is one of the most important compositions in honey bee propolis. The composition possesses anti-bacterial, anti-viral, anti-fungal, anti-oxidant, anti-inflammatory and anti-cancer properties. In this study we tried to predict bioinformatic interaction between CAPE and GP120. Molegro virtual docker (MVD) is used. The results obtained from docking showed us that the best pose which is derived from MolDock score for GP120 was -89.9759 with reranking score equal to -61. 1094. Bioinformatic studies show that Caffeic Acid Phenethyl Ester has interaction with Envelope glycoprotein GP120.
