Hydrological Trend Analysis Integrated with Landscape Analysis at the Watershed Scale (Case Study: Langat Basin, Malaysia)

In this study, the trends of water and sediment data collected from three hydrometer stations over the past 25 years of development in the state of Selangor, Peninsular Malaysia, were analyzed using the Mann–Kendall and Pettitt’s tests. Landscape metrics for establishing the relationship between land use changes and trends of hydrological time series were calculated. The hydrologic trends were also studied in terms of rainfall variations and man-made features. Results indicated upward trends in water discharge at the Hulu Langat sub-basin and sediment load at the Semenyih sub-basin. These increasing trends were mainly caused by rapid changes in land use. Upward trends of hydrological series at the Hulu Langat sub-basin matched its rainfall pattern. At the Lui sub-basin, however, trends of hydrological series and variations in rainfall and land use were not statistically significant

Application of SWAT for impact assessment of land use/cover change and best management practices : a review.

Globally, the quantification and evaluation of land use and cover changes on the hydrological status of river basins is a main concern. There is an urgent need for technologies and models that can quantify the impact of land use change and management practices in an organized manner. Approach: Soil and Water Assessment Tool (SWAT) integrated with Geographic Information System (GIS) has great potential in current estimation, future prediction and proper decision making in terrestrial ecosystems. This review discusses the current utilization of SWAT in impact assessment of land use/cover change and best management practices. Results: Deployment of SWAT and land use/cover simulation models for impact assessment improves accuracy, reduces costs, and allows the simulation of a wide variety of conservation practices at watershed scale. Conclusion: This review demonstrates the synergistic role of SWAT and GIS technologies in improving watershed management

Demographic Characteristics of Pediatric Burn in Shahid Motahhari Hospital from 2007-2011

Background: Severe burn is one of the major causes of morbidity and mortality in children and adolescents and is third most common cause of death among this age group. The aim of this study was to evaluate demographic characteristics of pediatric burn over a period of 5 years and the relationship between cause mortality in patients with burns. Method: In this cross sectional study, documents of children under 15 years, in Shahid Motahari hospital between 2007 and 2011 was evaluated. Variables such as age, sex, stay duration in hospital, burn cause, severity, accident cause burns and outcome of patients finally entered in SPSS v.16 and were analyzed. Results: In this study, 416 patients (34/8%) were female and 780 (65/2%) were male. Factors for burns in children include boiling water in 674 cases (56/4%), flame in 190 patients (15/9%), burns with flammable materials in 131 cases (11%), burns with a hot meal for 113 people (9/4%) and other hot bodies in 30 patients (2/5) and steam burns in 3 (0/3%). Increasing in burned body surface was significantly associated with mortality (P value= < 0.001). Burn severity in children who died was more than other children (P value= < 0.001). Also burn etiology was significantly different in patients who died and patients were discharged (P Value= 0.003). Conclusion: Based of the results of this study, burn in boys was more than girls and was common inpatients under 2 years of age. Thermal burns were the most common type of burns in children (95/4%) and hot water were also the most important cause in thermal burns in children (56/4%).Burn extent in the majority of children (75%), was less than 30% of the body surface and burns between 50 to 100% occurred in 6/3% of cases. Average stay duration in the hospital was 12/8 days and mortality rate was 7/2%. Area and depth of the burn injury were the most important determinants of mortality

The Rules of Forensic Medicine Examination in Diagnosis of Electrical injury in Childhood

Background: History taking is a duty that must get out in different situation as child's parents or in adults by themselves, to able provide the best helps in minimum time. Certainly, the information come out from history have significant effects on management plans. Case Presentation: A 16 months baby that transfers to ER department with complete cardiorespiratory arrest and after response to resuscitation the medical management was done for him. As history taking, he found unconsciousness near dress pan with wet dressing in bathroom. In physical exam the little impact traumatism on his/her head and face was detected. In blood and urine samples, there were not significant findings for toxicological screening. The physician requested for forensic specialist consultation for ruling out any child abuse doubt. The future examination was done by forensic team and they found the hyperkeratotic nodules on palmar surface of first phalange of right index finger due to electrocution. Conclusion: The history taking and following physical exam have greatest significant moment and the detailed and exact physical examination include whole parts of body, especially in children who couldn't present and complain about their problems completely

Characteristics of absconders from a general health service, Rasoul Akram Hospital in 2013

Introduction Absconding is an important health and security concern because of its adverse effect on patients, care providers, and the community. Studies are limited. Aim This study aimed to describe the characteristics of absconding events in Tehran. Material and methods In this analytical cross-sectional study, 334 absconders from 34 192 patients who were admitted to the Rasoul Akram Hospital in 2013 and escaped from the hospital were recruited. These patients were evaluated based on variables that included age, sex, marital status, hospitalization duration, smoking, alcohol use, addiction, psychiatric disorders or underlying disease, type of insurance, cause of hospitalization, time of scape, and cost of treatment. Results and discussion The study group consisted of 260 (77.8) males and 74 (22.2) females, with a mean age of 37.4 (SD = 17.1). Mean duration of hospitalization was 99 h (SD = 14.8). A total of 70 (21) patients were smokers, 14 (4.2) consumed alcohol, and 65 (19.5) were drug addicts. Psychiatric disorders were observed in 18 (5.4) patients, and underlying diseases were detected in 87 (26). Higher rates of escape were observed in single men (N = 162; 62.30) as well as married women (N = 52; 70.27). The most common time of escape was 12:00 PM. The highest number of escapes was observed in the month of July. Conclusions The present study identified single males, younger patients, psychiatric disease, underlying illness, and addiction as common features of escapees. Particular attention in observing, improvement in observation methods, and staff focusing on engagement could be helpful in decreasing the number of absconding events. © 2015 Warmi�sko-Mazurska Izba Lekarska w Olsztynie.

The Relationship between Environmental, Cultural and Chronological Factors with the Frequency, Cause and Type of Burn Injuries Admitted to the Trauma and Burn Center Motahari Hospital, during the Years 2007to 2011

Background:One of the most important health associated problem are events, which burns considered the most common of them. To prevent burn and reduce the complication and mortality rate, accurate information of epidemiology of burn is essential for planning properly.This study was conducted to determine the relationship between environmental and cultural factors and the type, cause and extent of burn injuries admitted to the trauma and burn center of Motahari hospital during 1386 to 1390.Methods: In this routine data base study, we recruited all burned patients whichreferred to trauma andburncenter of ShahidMotahari hospital between 2007 and 2011. Mainvariables includingeconomic conditions, season ofoccurrenceof the accident,the accident tocurriedonspecial occasions, yearof accident, accidentstatuson holidays, type of injury, cause of injury, injuryseverity, burnarea, anddemographic variables such asage and gender were entered in checklist from patient’s documents.Collected data were entered into softwareSPSS version 11 and were analyzed.Results:5511 patients were admitted to Motahari hospital during the April of 1386 to the end of 1390, from which 1448 (26.3%) cases were female and 4063 (73.7%) male. The mean age of subjects was 28.47 (SD=1.88).There was significant difference between different gender and etiology, so that men were burned more by oil, gasoline and diesel fuel rather than women.There was significant difference about the number of burned cases by the flame at different seasons of the year. Average number of people burned by gas cylinders,electricity,caraccident,bitumen was significantly different in different seasons.Conclusion:There were significant differences about burn injuries due to the gas cylinders,bitumen,electricity and car accidents in different seasons and months.To inform burn centers, principalship of these data increases their ability to manage populated and harmful days. According to the higher rate of explosive burn injury in the last month of the year producing harmless explosive materials can be so effective to support patients lives

Characteristics of traumatic brain injury among accident and falling down cases

Motor vehicle and falling down are responsible for the most number of traumatic injuries. This study aimed to compare the characteristics of traumatic brain injury among accident and falling down cases. In this analytical cross- sectional study, data were collected from the records of cadavers who died due to accident or falling down and referred to Kahrizak dissection hall, Tehran forensic medicine organization during 2013. A total of 237 subjects (183 (77.2) accident and 54 (22.8) falling down) with a mean age of 35.62 (SD=15.75) were evaluated. A number of 213 (89.9) were male. From accident group, scalp injury was seen in 146 (79.8), scalp abrasion in 122 (66.7), scalp laceration in 104 (56.8), sub skull bruising in 176 (96.3), skull fracture in 119 (65), hemorrhage in 166 (90.7), Subdural hemorrhage (SDH) in 155 (84.7), Subarachnoid hemorrhage (SAH) in 161 (88), Epidural hemorrhage (EDH) in 41 (22.4), contusion in 140 (76.5), and skull base fracture in 140 (76.5) of cases. In falling down group scalp injury was seen in 42 (77.8) cadavers, scalp abrasion in 38 (70.4), scalp laceration in 30 (55.6), sub skull bruising in 49 (90.7), skull fracture in 39 (72.2), Hemorrhage in 49 (90.7), SDH in 43 (79.6), SAH in 47 (87), EDH in 10 (18.5), contusion in 33 (61.1), and skull base fracture in 39 (72.2) of cases. There was no significant difference between these two groups (P Value> 0.05). Accident and falling down had no difference in terms of any injury or hemorrhage. © 2015 Tehran University of Medical Sciences. All rights reserved

An Operational Semantics for C/C++11 Concurrency

The C/C++11 concurrency model balances two goals: it is relaxed enough to be efficiently implementable and (leaving aside the "thin-air" problem) it is strong enough to give useful guarantees to programmers. It is mathematically precise and has been used in verification research and compiler testing. However, the model is expressed in an axiomatic style, as predicates on complete candidate executions. This suffices for computing the set of allowed executions of a small litmus test, but it does not directly support the incremental construction of executions of larger programs. It is also at odds with conventional operational semantics, as used implicitly in the rest of the C/C++ standards. Our main contribution is the development of an operational model for C/C++11 concurrency. This covers all the features of the previous formalised axiomatic model, and we have a mechanised proof that the two are equivalent, in Isabelle/ HOL. We also integrate this semantics with an operational semantics for sequential C (described elsewhere); the combined semantics can incrementally execute programs in a small fragment of C. Doing this uncovered several new aspects of the C/C++11 model: we show that one cannot build an equivalent operational model that simply follows program order, sequential consistent order, or the synchronises-with order. The first negative result is forced by hardware-observable behaviour, but the latter two are not, and so might be ameliorated by changing C/C++11. More generally, we hope that this work, with its focus on incremental construction of executions, will inform the future design of new concurrency models.This work was partly funded by a Gates studentship (Nienhuis) and by the EPSRC Programme Grant REMS: Rigorous Engineering for Mainstream Systems, EP/K008528/1

Into the depths of C: Elaborating the de facto standards

C remains central to our computing infrastructure. It is notionally defined by ISO standards, but in reality the properties of C assumed by systems code and those implemented by compilers have diverged, both from the ISO standards and from each other, and none of these are clearly understood. We make two contributions to help improve this error-prone situation. First, we describe an in-depth analysis of the design space for the semantics of pointers and memory in C as it is used in practice. We articulate many specific questions, build a suite of semantic test cases, gather experimental data from multiple implementations, and survey what C experts believe about the de facto standards. We identify questions where there is a consensus (either following ISO or differing) and where there are conflicts. We apply all this to an experimental C implemented above capability hardware. Second, we describe a formal model, Cerberus, for large parts of C. Cerberus is parameterised on its memory model; it is linkable either with a candidate de facto memory object model, under construction, or with an operational C11 concurrency model; it is defined by elaboration to a much simpler Core language for accessibility, and it is executable as a test oracle on small examples. This should provide a solid basis for discussion of what mainstream C is now: what programmers and analysis tools can assume and what compilers aim to implement. Ultimately we hope it will be a step towards clear, consistent, and accepted semantics for the various use-cases of C.We acknowledge funding from EPSRC grants EP/H005633 (Leadership Fellowship, Sewell) and EP/K008528 (REMS Programme Grant), and a Gates Cambridge Scholarship (Nienhuis).
