Jaffna peninsula in Sri Lanka is an area of intensive agriculture using extensive organic and inorganic nitrogenous compounds and hence, this study was focused on assessing vulnerability of karstic aquifer system with specific focus on nitrate contamination, and compare loads of nitrate from agriculture. The total number of the wells sampled in the Chunnakam aquifer is 44. The coverage of wells...
all analytical methods are generally based on the measurement of a parameter or parameters which are somehow related to the concentration of the species.an ideal analytical method is one in which the concentration of a species can be measured to a high degree precision and accuracy and with a high sensitivity. unfortunately finding such a method is very difficult or sometimes even impossible.in...
for several years, researchers in familiarity of efl teachers with post-method and its role in second and foreign language learners’ productions have pointed out that the opportunity to plan for a task generally develops language learners’ development (ellis, 2005). it is important to mention that the critical varies in language teaching was shown is the disappearances of the concept of method ...
Vulnerability assessment to delineate areas that are more susceptible to contamination from anthropogenic sources has become an important element for sensible resource management and land use planning. This contribution aims at estimating aquifer vulnerability by applying the DRASTIC model as well as utilizing sensitivity analyses to evaluate the relative importance of the model parameters for ...
در اکثر مناطق ایران آب های زیرزمینی که تامین کننده اصلی آب کشاورزی، شرب و مصارف صنعتی هستند در حال حاضر شدیداً تحت تأثیر برداشت بی رویه قرار گرفته است. با توجه به عدم امکان جای گزینی این منبع آب ارزشمند، محافظت از آن امری ضروری به نظر می رسد. دشت قزوین به علت شرایط خاص خود و وجود واحدهای صنعتی و فعالیت های کشاورزی، شهرها و شهرک های صنعتی متعدد در حال حاضر از مناطق بحرانی و آسیب پذیر است. در این ...
Parallelization aspects of a two-phase three dimensional Direct Simulation Monte Carlo (DSMC) method for modeling particle-laden gaseous flow in the vicinity of the Head-Disk Interface (HDI) gap in a modern Hard Disk Drive (HDD) enclosure are discussed in this work. Parallel performance metrics have been extracted and compared by executing this method on supercomputing platforms and various mul...
Surface hydrophobicity has recently been emphasized as an important parameter for functional correlation of proteins. However, evaluations of the parameter by different experimental techniques often do not correlate well with each other. In this paper we have compared surface hydrophobicity of a basic protein with those of beta-lactoglobulin, ovalbumin and lysozyme by fluorescence probe method ...
We present a 3D object tracking method using a single depth camera for Spatial Augmented Reality (SAR). The drastic change of illumination in a SAR environment makes object tracking difficult. Our method uses a depth camera to train and track the 3D physical object. The training allows maker-less tracking of the moving object under illumination changes. The tracking is a combination of feature ...
دشت عجبشیر در استان آذربایجان شرقی و در شمال غرب ایران واقع شده است. این دشت تأمینکنندۀ آب شرب، کشاورزی و صنعت شهرستان عجبشیر است. در این تحقیق با توجه به ویژگیهای هیدرولوژی و هیدروژئولوژی منطقۀ مطالعهشده، آسیبپذیری منابع آب زیرزمینی آبخوان در برابر عوامل آلاینده با استفاده از دو مدل DRASTIC و SI در محیط سیستم اطلاعات جغرافیایی پهنهبندی شده است. در مدل DRASTIC از هفت پارامتر شامل عمق سطح...
