Climate Change Induced Land Degradation and Socio-Economic Deterioration: A Remote Sensing and GIS Based Case Study from Rajasthan, India  [PDF]
Akram Javed, Sayema Jamal, Mohd Yousuf Khandey
Journal of Geographic Information System (JGIS) , 2012, DOI: 10.4236/jgis.2012.43026
Abstract: The present study attempts to identify and quantify climate change induced land degradation at watershed and village level in Jaggar Watershed of Eastern Rajasthan using remote sensing and GIS technique. The study utilizes Standard Geocoded FCC LISS II data of 1989, and LISS III data of 1998 and 2009 on 1:50,000 scale for Land use/land cover mapping. Maps were digitized, edited and analyzed in GIS to ascertain land use/land cover changes. Comparative analysis of the Land use/land cover statistics and village level household survey reveals that climate change has severely affected land use/land cover especially agriculture land. Agricultural land in the watershed has decreased from 12,026 ha (34%) to 10,400 ha (29.65%) from 1998 to 2009. The area occupied by surface water resources of the major water body has decreased by 207 ha owing to decline in rainfall over the years. Climate data analysis suggests that average maximum and minimum temperatures during the period 1977-2007 have increased by 1.2?C and 0.4?C respectively. Increasing trends of temperature suggests warming up of the area. Decline of ground water table by 1 - 2 m on annual basis coupled with significant drawdown has led to water scarcity in many parts of the watershed. The water table has gone down to a depth of 240 feet, which was reported at 60 - 70 feet 20 years back. The area has shown sharp decline of rainfall by 269 mm from 1977 to 2007. The survey results show that there has been shift in the cropping pattern during the last 20 years due to change in climate as well as decline in availability of water for irrigation. Climate change seems to have played a key role in Jaggar watershed resulting in land degradation and making rainfed agriculture more vulnerable.

Sayema Jamal, Akram Javed, Yousuf Khanday
Journal of Environmental Protection (JEP) , 2016, DOI: 10.4236/jep.2016.78102
Abstract: The present work attempts to assess the land cover changes at watershed level and status of land degradation in Mithri Watershed lying in the semi-arid tracts of Western Rajasthan, using time series climate data and remote sensing data and GIS techniques. The study also has a strong field component in the form of village wise surveys to record observations on climatic changes, agriculture, socio-economic condition of the community, water availability etc. Integration of remote sensing technique along with climate data analysis and household surveys, Group discussion and Participatory rural appraisal (PRA) was conducted to record land use/land cover changes and its impact on socio-economic condition of the people. Degradation mapping of the area reveals that area is affected by forest degradation, scrub erosion and salinization. Anthropogenic factors like fuel wood and timber extraction, livestock grazing etc. are also responsible for forest degradation. People have shifted from cash crops such as cotton to maize, barley and cereal during the last two decades.

TELKOMNIKA : Indonesian Journal of Electrical Engineering , 2012, DOI: 10.11591/telkomnika.v10i2.686
Abstract: Diabetic retinopathy is an eye disease caused by the increase of insulin in blood and it is one of the main cuases of blindness in idusterlized countries. It is a progressive disease and needs an early detection and treatment. Vascular pattern of human retina helps the ophthalmologists in automated screening and diagnosis of diabetic retinopathy. In this article, we present a method for vascular pattern ehnacement and segmentation. We present an automated system which uses wavelets to enhance the vascular pattern and then it applies a piecewise threshold probing and adaptive thresholding for vessel localization and segmentation respectively. The method is evaluated and tested using publicly available retinal databases and we further compare our method with already proposed techniques.

Implementation of Variable Least Significant Bits Stegnographyusing DDDB Algorithm
Sahib Khan,Muhammad Haroon Yousaf,Jamal Akram
International Journal of Computer Science Issues , 2011,
Abstract: Nobody can deny the importance of secure communication.Different techniques are being utilized to achieve this task. Image Stegnography is one such method in which we hide data in an otherwise ordinary image. In this paper, a novel Stegnographic technique named as Variable Least Significant Bits Stegnography (VLSB) is proposed. To implement VLSB, we designed an algorithm named as Decreasing Distance Decreasing Bits Algorithm (DDDBA). In each test we performed, the data hiding capacity was always greater than 50 % ( a barrier considered in image Stegnography), ranging up to 69 % with signal to noise ratio varying from 10 db to 5 db respectively. The DDDBA provides self encryption mechanism in VLSB Stegnography, making the Steganalysis more difficult.
Comparison of Aerobic and Lime Stabilization Methods for Evaluation of Sewage Sludge Reuse
Akram Jamal,Nafise Norieh,Mahdi Farzadkia
Journal of Environmental Science and Technology , 2011,
Abstract: The main objective of this research was the examination of effectiveness of lime dose in order to stabilization of sewage sludge and comparison of lime stabilized sludge reuse with aerobic digested sludge reuse. Lime and aerobic stabilization were carried out in two laboratory reactor with 40 L capacity. The sludge samples were taken from the return activated sludge line in four times. Lime was used at various ratios and the mixture was stabilized for 30 days. During the lime hydrated stabilization pH values were significantly increased from 7 to 12.5. Also, aerobic digester was loaded with raw sludge and mixed by sufficient amount of air for 30 days. The results indicate that the lime addition with the dose of 0.4 g Ca(OH)2 g-1 DS could completely inactive a high amount of fecal coliforms within 1 h and in all of the times was lower than 1000 MPN g-1 DS after 30 days (p<0.01). But after 30 days, fecal coliforms density in aerobic digested sludge could not achieve to Class A of USEPA category. In two stabilization methods, density of viable helminths ova could not reduce to 1 ova/4 g DS and could not achieve to Class A of USEPA category. Therefore, these methods could be achieved the reduction requirement set by USEPA for class B (p<0.01) and the products could be well used as a landfill cover or a soil conditioner. Finally, our study confirmed that lime sludge stabilization has a higher hygienic effect and more cost-effective than aerobic stabilization, specially, when such sludge is used to dung and modify acid soils.
Experiential Basis of Meaning in a Semantic Associative Test: A Move toward an Embodied Explanation of Primary Metaphor  [PDF]
Habibollah Ghassemzadeh, Jamal Abedi, Akram Khamseh, Uta Sassenberg, Maryam Rahat, Elham Eshtad, Mansooreh Rajablo
Psychology (PSYCH) , 2017, DOI: 10.4236/psych.2017.812123
Abstract: The concept of meaning has undergone many changes in the course of scientific study of language, thought and behavior. At first, it was explained as something which happens in the mind and then is changed to a product of association of ideas. Today, however, new meaning of meaning has emerged with the emphasis on the experiential basis as has been formulated in the concept of metaphoric expression. In this paper, we report a preliminary study on meaning as measured by a semantic-associative test in four different cultures (Iranian, German, Arabic and American). The findings have been explained in the framework of the primary metaphors and embodiment theory.

Saudi Journal of Kidney Diseases and Transplantation , 2011,
Abstract: Peritoneal dialysis (PD) is one of the modes of renal replacement therapy being utilized for the management of end-stage renal failure in King Khalid University Hospital, King Saud Uni-versity, Riyadh, for more than two decades. The aim of this study was to evaluate the complications related to PD as well as its outcome in patients on this mode of therapy during the period between January 2004 and December 2008. There were 72 patients included in the study, of whom 43 were females. The average age was 50.7 ± 30.1 years (14-88 years). Diabetes was the leading cause of end-stage renal disease (ESRD) seen in 40.2% of the study patients. Twenty-eight patients (38.9%) were on continuous ambulatory peritoneal dialysis (CAPD) and 44 (61.1%) were on automated PD (nocturnal intermittent peritoneal dialysis, NIPD or continuous cycler peritoneal dialysis, CCPD). The mean du-ration on PD of the study patients was 25.5 ± 16.58 months (1-60 months). The peritonitis rate was one episode per 24.51 patient-months or one episode per 2.04 patient-years. The incidence of peritonitis per person-year was calculated as 0.42. The leading causative agent for peritonitis was Staphylococcus (32%). Exit-site infection (ESI) rate was one episode per 56.21 patient-months. The incidence of ESI was 0.214 per person-years. The most common infective organism for ESI was Pseudomonas aeru-ginosa (58.8%). At the end of 5 years, 35 patients were continuing on PD, 13 patients were shifted to hemodialysis (HD), nine patients underwent renal transplantation, and six patients were transferred to other centers. Among the 13 patients who were shifted to HD, four patients had refractory peritonitis, four others had catheter malfunction, three patients had inadequate clearance on PD and two patients had lack of compliance. A total of 11 patients died during the study period, giving an overall mortality rate of 15.27% for the five-year period. Our study suggests that there has been considerable improvement in overall outcome and mortality in patients on PD. Additionally, a marked reduction in the infectious and non-infectious complications was noted with the peritonitis and ESI rates in our center being comparable to other studies and international guidelines.

Jamal Raiyn
Wireless Engineering and Technology (WET) , 2011, DOI: 10.4236/wet.2011.22012
Abstract: This paper describes a novel self-optimized approach for resource management based on the cognitive radio in the cellular networks. The cognitive radio techniques offer several features like autonomy, sensing and negotiation. The use of cognitive radio approach gives greater autonomy to the base stations in the cellular networks. This autonomy allows an increase in flexibility to deal with new situations in the traffic load. The negotiation strategy is used to avoid conflicts in the resource allocation. The goal of the cognitive radio scheme is to achieve a high degree of resource usage and a low rate of call blocking in the cellular systems.
