Rust belt cities are largely threatened by a waste of urban space at their core;however,in developing countries where land resources are widely used as instruments for macroeconomic stabilization,urban periphery is also at risk of being underutilized due to land hoarding.Such geographic differences entail new knowledge about how,where,and why underutilized lands are regenerated in the city.Furthermore,rapid urban growth imposes development disparity and mixed underutilization issues on cities in developing countries;therefore,how the geo-information obtained by the regeneration of different underutilized lands differs will be valuable for urban planners and policymakers to make prudent trade-offs.To fill these gaps,we conducted a sequential investigation into the regeneration of underutilized lands in a representative rust belt city – Changchun City in Northeast China,in an attempt to measure the regeneration pattern and analyze the underlying determinants using the Classification and Regression Trees analysis.The results indicated that,of all underutilized lands,increments of vacant lot and remnant cultivated land continued to plague the expanding urban periphery during 2016–2019.In a way,reduced underutilized lands alleviated land use conflicts at the city core.Nearly 23% of the underutilized areas had been regenerated,dominated by realty development,with most converted to residential lands,ecological lands and industrial lands.On the contrary,conversion to transportation lands and parking lots seemed to avoid the rapidly expanding sites.The regeneration rates in a certain area can be increased by a multitude of factors,including denser,simply structured land underutilization,abundant ecosystem services nearby and accessibility to public infrastructures.Site conditions such as residential density and accessibility may have fueled the regeneration associated with residential purposes,while regeneration of industrial development was closely associated with the underutilization density and parcel regularity.This r

Geriatric trauma patients require special consideration. They frequently have comorbidities and reduced physiologic reserves, influencing treatment decisions and outcomes. Hence, a comprehensive approach is fundamental to ensure better results. The authors retrospectively evaluated the profile of 332 cases of geriatric trauma over ten years (January 2010-December 2019) at National Orthopaedic Hospital Enugu, in South-East Nigeria. The mean age of patients was 74.78 years (SD = 8.69), with females presenting at a later age than men (76.05 vs 73.69 years), p = 0.013. The commonest mechanism of injury was ground-level fall (47.59%), with proximal femoral fractures being the most common (41.27%). Only 47% of geriatric patients presented to a hospital within 24 hours following injury, and the mean duration of admission was 28 days. Approximately 77% of patients had operative care, and 68.67% expressed satisfaction with the outcome of their management. The mortality rate was 2.11%. In conclusion, most geriatric fractures require surgical intervention and education to facilitate early hospital presentation is needed.

developing countries,which contribute 90%of global aquaculture production,are considered global climate risk hotspots.However,no study focuses on measuring district-or sub-national-level aquaculture vulnerability to climatic hazards or disasters.This study has measured the level of aquaculture vulnerability to climate variability and change in all 64 districts of Bangladesh using a composite vulnerability index approach(using 19 climatic,environmental and socio-economic indicators)and geographical information system(GIS).The results reveal that aquaculture in 12 districts namely Satkhira,Mymensingh,Panchagarh,Lalmonirhat,Nilphamari,Thakurgaon,Sunamganj,Dinajpur,Kurigram,Noakhali,Lakshmipur,and Cox's Bazar have very high vulnerability(in order of highest to lowest vulnerability),which are explained by their higher level of exposure,moderate level of sensitivity,and lower to moderate level of adaptive capacity.Among these,8 districts belong to inland and 4 districts to coastal regions of the country.Three districts,namely Dhaka,Chittagong,and Bandarban,have the lowest level of aquaculture vulnerability(in order of lowest to highest vulnerability)mainly because of very high adaptive capacity and moderate or low level of sensitivity and exposure.This study will punctuate the vulnerability of inland aquaculture and develop and prioritize actions to reduce the climatic impacts.

In the field of renewable energy, self-provided research in developing countries is barely present, but most welcomed. The creation of know-how and self-development of technologies should reduce the dependence on industrialized countries for both materials and knowledge. This work presents technological and social issues related to the construction of a low budget solar laboratory in Mozambique. The goal is to demonstrate that scientific level research can be carried out in developing countries by using affordable solutions without sacrificing quality of the results. For this investigation, a solar laboratory was built in 2011 at Universidade Eduardo Mondlane of Maputo. The laboratory enables measurements?to evaluate solar?thermal and?photovoltaic-thermal?hybrid collectors.?Thanks to the?flexibility of the system,?students and teaching staff can?add/remove equipment and develop customised local research programs. In addition, a course on the principles of solar energy and collector simulation for local students was taught. The needed data acquisition devices usually used in Europe were compared with cheaper and easy-maintenance ones. Calibration and estimation of the uncertainty were successfully performed. Approximately 9% of inaccuracy in the measurement was introduced by the cheaper equipment, but the investment cost was reduced by more than 90%. Other issues, results and future recommendations are shown.

环境科学学报:英文版 2023年第11期133卷 152-160页

作者： Xiaoqiao Jiao Rui Xiong Zhihan Luo Yaojie Li Hefa Cheng Audil Rashid Guofeng Shen Shu Tao College of Urban and Environmental Sciences Peking UniversityBeijing 100871China Faculty of Science Botany DepartmentUniversity of GujratGujrat 50700Pakistan College of Environmental Science and Technology Southern University of Science and TechnologyShenzhen 518055China

Solid fuel use(SFU)is common in most developing countries and would release many hazardous air pollutants posing high risks on human health.The Global Burden of Disease(GBD)study highlighted risks associated with household SFU in Pakistan,however,high uncertainties prevail because of scanty data on SFU and unaccounted energy stacking.This study conducted a field campaign aiming at collecting first-hand data on household energy mix in Pakistan.The first survey was in Punjab and Azad Kashmir,and revealed that stacked energy use was pervasive,especially for cooking.The stacking was found to be much more obvious in SFU households(defined as those using SFU dominantly)compared to those non-SFU.There were significantly substantial differences between Azad Kashmir and Punjab because of distinct resources available and economic conditions.Woody materials comprised up to nearly 70% in Azad Kashmir,but in Punjab,gas was frequently used for cooking.Only investigating primary household energy would probably overestimate main energy types that being used for a longer time but underestimated other supplements,suggesting the preference of multiple-energy surveys in household energy studies.

Decomposing drivers of transportation energy consumption and carbon dioxide emissions for the Philippines： the case of developing countries

引用

Frontiers in Energy 2018年第3期12卷 389-399页

作者： Neil Stephen LOPEZ Anthony S.F. CHIU Jose Bienvenido Manuel BIONA Mechanical Engineering Department De La Salle University Manila1004 the Philippines

Global CO2 emissions increased by 57.9% from 1990 to 2014, of which 21% is known to be from the transportation sector. In line with policy development, driving forces to energy consumption and emissions may be determined using decomposition analysis techniques. However, the detail of information required to perform such studies for the transportation sector in developing countries can be challenging. An attempt was made in this study to formulate a decomposition analysis framework considering data availability and limitation in developing countries. Furthermore, a suggestion of adjusting transport activity data using average oil price was proposed. An illustrative case study in the Philippines revealed that the most significant driver was transport activity, followed by energy intensity, and then population growth, which was both similar and contrary to all previous studies performed in developed and rapidly urbanizing countries, which pointed out to transport activity as the primary contributing force. For the Philippines, transport activity was an inhibiting force, whereas energy intensity was the primary contributing factor. The difference could be explained by the differences in mode shares and quality of life between countries. Looking at private vehicle ownership data, it is observed that growth rates are higher in the rural, than in the urban centers. Deriving from the findings, developing a comprehensive public transport plan is recommend for future growth areas, expansion and modernization of public transport services in the city, and strategic deployment of transport policies.

Journal of Cancer Metastasis and Treatment 2022年第1期8卷 459-475页

作者： Vito Filbert Jayalie Sri Mutya Sekarutami Department of Radiation Oncology Faculty of Medicine Universitas Indonesia-Dr.Cipto Mangunkusumo HospitalJakarta 10430Indonesia

Cancer has caused a tremendous burden in developing countries.Oncolytic virus(OV)therapy is an emerging modality with the potential to be a single or combination agent with radiation therapy(RT).Following entry of OV to the cell,OV will replicate and assemble before exiting from tumor cells.Construction of OV can be done by modifying the capsid,genome,and chemical material of viruses.Irradiation will induce double-strand breaks,and further integration of OV with DNA damage response pathway will interact with the MRE11-Rad50-Nbs1 complex to regulate the mobilization of E4 open reading frame 6,protein phosphatase 2A,poly(ADP-ribose)polymerase,apoptosis-inducing factor,and topoisomerase-IIβ-binding protein 1.Degradation of DNA-dependent protein kinase catalytic subunits via human simplex virus-1-infected cell polypeptide 0 will inhibit DNA repair.OV and RT have a synergistic interaction to cause viral oncolysis and upregulation of immune response.In the clinical setting,most studies have demonstrated that OV is a safe treatment with less toxicity.Moreover,OV+RT resulted in longer median survival(62.4 vs.37.7 weeks)in malignant glioma.

Pancreas transplantation significantly improves the quality of life for people with type 1 diabetes,primarily by eliminating the need for insulin and frequent blood glucose measurements.Despite the growing numbers of solid organ transplantations worldwide,number of pancreas transplantations in the developing countries`remain significantly low.This difference of pancreas transplantation practices was striking among the participating countries at the 1st International Transplant Network Meeting which was held in Turkey on 2018.In this meeting more than 40 countries were represented.Most of these counties were developing countries located in Africa,Middle East or Asia.The aim of this article is to identify the challenges and limiting factors for pancreas transplantations in these developing countries,by exploring the Turkish example.The challenges faced by the developing countries are broadly classified in four categories;wait-listing,donor pool,team work and follow up.Under these categorical titles,issues are further discussed in detail,giving examples from Turkish practice of pancreas transplantation.Additionally,several solutions to these challenges have been proposed-some of which have already been undertaken by the Turkish Ministry of Health.With the insight and methods presented in this article,pancreas transplantation should be made possible for the potential recipients in the developing countries.
