Volatile organic compounds(VOCs)are the important precursors of the tropospheric ozone(O3)and secondary organic aerosols(SOA),both of which are known to harm human health and disrupt the earth’s climate *** this study,VOC emission factors,O3 and SOA formation potentials were estimated for two types of industrial boilers:coal-fired boilers(n=3)and oil-fired boilers(n=3).Results showed that EVOCs concentrations were more than nine times higher for oil-fire d boilers compared to those for coal-fired *** factors ofΣVOCs were found to be higher for oil-fired boilers(9.26-32.83 mg-VOC/kg)than for coal-fired boilers(1.57-4.13 mg-VOC/kg).Alkanes and aromatics were obtained as the most abundant groups in coal-fired boilers,while oxygenated organics and aromatics were the most contributing groups in oil-fired ***,n-hexane and o-ethyl toluene were the abundant VOC species in coal-fired boiler emissions,whereas toluene was the most abundant VOC species emitted from oil-fired boilers.O3 and SOA formation potentials were found 12 and 18 times,respectively,higher for oil-fired than for coal-fired *** OFP ranged from 3.99 to 11.39 mg-O3/kg for coal-fired *** oil-fired boilers,total OFP ranged from 36.16 to 131.93 mg-O3/***,total secondary organic aerosol potential(SOAP)ranged from 65.4 to 122.5 mg-SOA/kg and 779.9 to 2252.5 mg-SOA/kg for the coal-fired and oil-fired boilers,respectively.

Chinese Journal of Traumatology 2014年第1期17卷 60-62页

作者： sunil Kumar Akhilesh Rathi sunil Sehrawat Vikas gupta Jatin Talwar Sumit Arora Central Institute of Orthopaedics Vardhman Mahavir Medical College & Associated Safdarjung Hospital New Delhi 110029 India

Open anterior dislocation of the hip is a very rare injury, especially in adults. It is a hyperabduction, external rotation and extension injury. Its combination with open posterior dislocation of the elbow has not been de- scribed in English language-based medical literature. Pri- mary resuscitation, debridement, urgent reduction of dislocation, and adequate antibiotic support resulted ingood clinical outcome in our patient. At 18 months follow- up, no signs of avascular necrosis of the femoral head or infection were observed.

Multiple bilateral lower limb fractures in a 2-year-old child： previously unreported injury with a unique mechanism

引用

Chinese Journal of Traumatology 2014年第5期17卷 298-300页

Fall from height is a common cause of unintentional injuries in children and accounts for 6% of all trauma-related childhood deaths, usually from head injury. We report a case of a 2-year-old child with multiple fractures of the bilateral lower limbs due to this reason. A child fell from a height of around 15 feet after toppling from a balcony. He developed multiple fractures involving the right femoral shaft, right distal femoral epiphysis (Salter Harris type 2), right distal metaphysis of the tibia and fibula, and undisplaced Salter Harris type 2 epiphyseal injury of the left distal tibia. There were no head, abdominal or spinal injuries. The patient was taken into emergency operation theatre after initial management which consisted of intravenous fluids, blood transfusion, and splintage of both lower limbs. Fracture of the femoral shaft was treated by closed reduction and fixation using two titanium elastic nails. Distal femoral physeal injury required open reduction and fixation with K wires. Distal tibia fractures were closely reduced and managed nonoperatively in both the lower limbs. All the fractures united in four weeks. At the last follow-up, the child had no disability and was able to perform daily activities comfortably. We also proposed the unique mechanism of injury in this report.

Evaluation of Stipulated Conditions Imposed at the Time of Grant of Environment Clearance from the Perspective of Implementation of Compliance-A Case Study for Construction Projects in India

引用

Chinese Journal of Urban and Environmental Studies 2015年第1期3卷 75-91页

作者： gupta sunil SHARMA Sanjay SAINI Randeep Singh National Institute of Technical Teachers Training & Research (NITTTR) Green Economy Initiatives Private Limited

The purpose of the paper is to discuss the stipulated conditions imposed at the time of grant of environment clearance from the perspective of implementation of compliance in case of construction projects in India. Conditions as imposed on 40 different building and construction projects in India from 2008 to 2013 are studied and evaluated and for a ready reference a sample of 14 representative project types is given in the paper. Based on the evaluation, we conclude that the laid down conditions are general in nature and more or less same irrespective of the location or type of the project may be an educational institute, hospital, office, hotel, group housing, bus terminus, or multiplex and whether it graded platinum or bronze in rating or ungraded. The impacts of the project nowhere find a mention in the stipulated conditions and thus there is no correlation between the conditions imposed and the baseline environment parameters. There is a dire need to rework the stipulated conditions itself on the lines of environment management plan proposed by the project proponent including setting apart the cost of implementation, if an effective compliance as envisaged by Ministry of Environment and Forests, Government of India is to be achieved.

目的探讨质量源于设计(QbD)工具在评估印度5个不同地区余甘子地理变异中的应用。方法在本实验中,采用简化四次模型的Box-Behnken设计,运行105次,结合使用Design Expert软件进行随机响应面映射。本研究使用了三种不同的浸提方法(索氏浸提、浸渍浸提和超声浸提)以及三种溶剂[蒸馏水、甲醇和水-甲醇混合物(50:50 v/v)]。采用气相色谱-质谱法(GC-MS)测定并分析余甘子的抗氧化活性、总黄酮含量(TFC)和总酚含量(TPC),以鉴定其主要成分。结果QbD叠加图显示余甘子的提取值不低于30%w/w,2,2-二苯基-1-三硝基苯肼(DPPH)不低于60%mcg/mL(微克每毫升),TFC不低于75 mg QE/g(毫克槲皮素当量每克干原料),TPC不低于80 mg GAE/g(毫克没食子酸当量每克干原料)。此外,(GC-MS)数据证实了余甘子的生物活性存在变异。结论本研究模型能较好的描述浸提值、DPPH、TFC和TPC的变化。QbD方法可能倾向于在浸提过程中优先考虑彻底性,最终提高浸提产品的质量。

Polymethylmethacrylate bone cements and additives: A review of the literature

引用

World Journal of Orthopedics 2013年第2期4卷 67-74页

作者： Manit Arora Edward KS Chan sunil gupta Ashish D Diwan St George Clinical School University of New South Wales Kogarah New South Wales 2217 Australia Royal Prince Alfred Clinical School University of Sydney Camperdown New South Wales 2050 Australia South Western Sydney Clinical School University of New South Wales Liverpool New South Wales 2170 Australia Orthopaedics Research Institute and Department of Orthopaedic Surgery St George Hospital Kogarah New South Wales 2217 Australia

Polymethylmethacrylate(PMMA) bone cement technology has progressed from industrial Plexiglass administration in the 1950 s to the recent advent of nanoparticle additives. Additives have been trialed to address problems with modern bone cements such as the loosening of prosthesis, high post-operative infection rates, and inflammatory reduction in interface integrity. This review aims to assess current additives used in PMMA bone cements and offer an insight regarding future directions for this biomaterial. Low index(< 15%) vitamin E and low index(< 5 g) antibiotic impregnated additives significantly address infection and inflammatory problems, with only modest reductions in mechanical strength. Chitosan(15% w/w PMMA) and silver(1% w/w PMMA) nanoparticles have strong antibacterial activity with no significant reduction in mechanical strength. Future work on PMMA bone cements should focus on trialing combinations of these additives as this may enhance favourable properties.
