The Effects of China-EU Trade on CO2 Emissions  [PDF]
Hui Zhou, Jie Cao, Jichuan Sheng
Low Carbon Economy (LCE) , 2013, DOI: 10.4236/lce.2013.44A002
Abstract:

Production for international trade has played an important role in driving the rapid increase of Chinese CO2 emissions. This paper uses input-output analysis to quantitatively estimate the effect of the bilateral trade between China and its present largest trading partner, the European Union (EU), on both national and global CO2 emissions. The results show that under the bilateral trade, China’s emissions from 2002 to 2008 increased by 2458 MMT (6.64%), and the EU’s emissions decreased by 539 MMT (1.81%). From a global perspective, the trade led to an increase of 1919 MMT CO2 in the world’s total emissions. The trading pattern is not dominated by pollution haven effect but by the comparative advantages in factor endowments. It is suggested that a consumer responsibility-based accounting system of national CO2 inventory should be introduced in replace of the present producer responsibility-based one. In order to achieve cost efficiency in emissions reduction in the new accounting system, more CDM programs could be established.

Solution of a sound field generated by the vibrating surface of a body moving at small Mach number
Tongqing Wang,Sheng Zhou
Chinese Science Bulletin , 1998, DOI: 10.1007/BF02885519
Abstract: An approach to calculate the sound field generated by the Vibrating surface of a body with arbitrary shape moving at a small mach number has been developed by using acoustical analogy. A governing equation to calculate the sound pressure on the surface exited by its vibration has been derived on the basis of the united aerodynamics and aeroacoustics approach by Farassat and Long, and the sound field would be determinate. The cases relating to the sound sources of static sphere and moving compact pulsating sphere give a good check for the approach.
Pyrolytic and Kinetic Characteristics of the Thermal Decomposition of Perilla frutescens Polysaccharide
Quancheng Zhou, Guihua Sheng
PLOS ONE , 2012, DOI: 10.1371/journal.pone.0052597
Abstract: The thermal decomposition of Perilla frutescens polysaccharide was examined by thermogravimetry, differential thermogravimetry, and differential thermal analysis. The results showed that the mass loss of the substance proceeded in three steps. The first stage can be attributed to the expulsion of the water from ambient temperature to 182°C. The second stage corresponded to devolatilization from 182°C to 439°C. The residue slowly degraded in the third stage. The weight loss in air is faster than that in nitrogen, because the oxygen in air accelerated the pyrolytic reaction speed reaction. The heating rate significantly affected the pyrolysis of the sample. Similar activation energies of the degradation process (210–211 kJ mol?1) were obtained by the FWO, KAS, and Popescu techniques. According to Popescu mechanism functions, the possible kinetic model was estimated to be Avrami–Erofeev 20 g(α) = [?ln(1–α)]4.

American Journal of Plant Sciences (AJPS) , 2011, DOI: 10.4236/ajps.2011.26096
Abstract: The wheat roots membrane separates the cell from the environment around it and encloses the cell contents. The pro-tein secondary structure and thermal stability of the plasma membrane of wheat root have been characterized in D2O buffer from 20°C to 90°C by Attenuated total reflection Fourier transform infrared spectroscopy (ATR-FTIR). Quantitative analysis of the amide I band (1700 - 1600 cm–1) showed that the plasma membrane proteins contains 41% α-helix, 16% β-sheet, 18% turn, and 25% disorder structures at 20°C. At elevated temperatures from 25°C up to 90°C, the α-helix and the β-sheet structure unfold into turns and the disorder structure, with a major conformational transition occurring at 50°C. There is a rapid decline in H+-ATPase activity of plasma membrane from 35°C to 55°C and it remain very low level H+-ATPase activity of PM from 55°C to 90°C. Therefore the protein conformational transition was one of reasons of loses H+-ATPase activity of plasma membrane.
Climate Suitability and Vulnerability of Winter Wheat Planting in Gansu under the Background of Global Warming  [PDF]
Xing Wang, Yuhe Ji, Guangsheng Zhou, Sheng Wang, Xiaoying Yao
Journal of Geoscience and Environment Protection (GEP) , 2019, DOI: 10.4236/gep.2019.74016
Abstract: Winter wheat is the main food crop in China. Gansu Province is a traditional winter wheat growing area, and its planting range is limited by the thermal conditions of winter. The average temperature in Gansu Province increased by 0.28°C per decade, higher than the China’s and global average, and the warming in winter was more obvious. Therefore, it is necessary to study the climate suitability and vulnerability of winter wheat planting in Gansu. In this paper, the maximum entropy model Maxent and Arcgis software are used to select six major climatic factors including annual total radiation, annual precipitation, the warmest monthly average temperature, the coldest monthly average temperature, annual average temperature, and annual extreme minimum temperature, which construct winter wheat planting distribution-climate relationship model that studies the climate suitability and vulnerability of winter wheat during the period 1961-2015. Studies have shown that the average cold weather and annual extreme minimum temperature are the most important climatic factors affecting winter wheat in Gansu, which can reflect the low temperature conditions that winter wheat can tolerate. However, the main winter wheat planting areas in Gansu Province are distributed in arid and semi-arid rain-fed agriculture areas. Precipitation and total annual radiation are also very important constraints. At the same time, climate change has little effect on winter wheat in Gansu Province, and the area of suitable area fluctuates slightly. It shows moderate adaptation in each evaluation period.

Advances in Molecular Imaging (AMI) , 2012, DOI: 10.4236/ami.2012.21001
Abstract: The focal and diffuse cerebral white matter injury can be caused by treatment with radiation therapy for cranial tumors. However, the literature rarely describes a MRI finding in radiation-induced delayed extensive cerebral injury. Our objective was to report a rare case who had a delayed extensive hyperintensity injury in brain on MRI after radiation therapy due to nasopharyngeal cancer. A MRI was performed on a 40-year-old patient with extensive brain damage who had the radiation therapy two years ago.MRI finding was evaluated. On MRI, T2-weighted MRI showed an extensive hyperintensity after treated by irradiation. The radiographic pattern of extensive cerebral injury is relatively distinct. It involves the white matter and gray matter in cerebral, cerebellum, medulla oblongata, pons, internal capsule and thalamus bilaterally. Our observations demonstrate that the extensive hyperintensity lesions in brain on MRI after radiation therapy is a cortical laminar necrosis and white matter myelinolysis.

Abstract: Purpose To present rare benign orbital tumors with bone destruction in children who could not be diagnosed pre-surgically and may simulate malignant ones. Methods A retrospective review of cases. Clinical, operative and pathological records in all children with a diagnosis of benign orbital tumors who showed remarkable bone destruction at a tertiary Ophthalmic Center in China between Jan 1, 2000 and Dec 31, 2009 were reviewed. All patients had definitive histopathologic diagnosis. Results Eight patients with benign orbital tumors showed obvious bone destruction, including six cases of eosinophilic granuloma, one case of leiomyoma and one case of primary orbital intraosseous hemangioma. Among them, three patients were females and five patients were males. Tumors were unilateral in all cases, with both the right and left side affected equally. Age ranged from 3 to 7 years (mean 4.1 years). Symptom duration ranged from 1 to 5 weeks (mean 4.8 weeks). Eyelid swelling and palpable mass were the most common complaint. There was no evidence for multifocal involvement in cases with eosinophilic granuloma. Among six patients with eosinophilic granuloma, two were treated with low dose radiation (10 Gy), three received systemic corticosteroid and one was periodically observed only after incisional biopsy or subtotal curettage. There was no postoperative therapeutic intervention in the two patients with leiomyoma and intraosseous hemangioma. All eight patients regained normal vision without local recurrence after a mean follow-up time of 32.8 months. Conclusion Benign orbital tumors such as isolated eosinophilic granuloma, leiomyoma and primary orbital intraosseous hemangioma may show remarkable bone destruction.

Abstract: evention of diabetes in hypertensive patients: Results and implications from the VALUE trial Review (3996) Total Article Views Authors: Ming-Sheng Zhou, Ivonne Hernandez Schulman Published Date April 2009 Volume 2009:5 Pages 361 - 368 DOI: http://dx.doi.org/10.2147/VHRM.S4331 Ming-Sheng Zhou, Ivonne Hernandez Schulman Nephrology-Hypertension Section, Veterans Affairs Medical Center and Division of Nephrology and Hypertension and Vascular Biology institute, University of Miami Miller School of Medicine, Miami, FL, USA Abstract: A growing number of experimental and clinical studies have provided evidence indicating that pharmacological blockade of the renin–angiotensin system (RAS) by either angiotensin-converting enzyme inhibitors or angiotensin type 1 receptor blockers reduces the incidence of new onset type 2 diabetes in subjects with hypertension and/or cardiovascular disease, independently of antihypertensive and cardiovascular protective effects. The beneficial effects of RAS inhibition on the development of diabetes have been largely attributed to improvements in peripheral insulin sensitivity and glucose metabolism. This review focuses on recent experimental and clinical evidence supporting the role of RAS inhibition in the reduction of new onset type 2 diabetes and the mechanisms that may be involved.
