Primary Production Dynamics of Two Dominant Macrophytes in Wular Lake, a Ramsar Site in Kashmir Himalaya
Naseer Ahmad Dar,Aadil Hamid,Bashir Ahmad Ganai,Sami Ullah Bhat
Ecologia Balkanica , 2012,
Abstract: Growing season changes in the organic matter, organic carbon and chlorophyll content of the two dominant macrophytes, Nymphoides peltatum and Ceratophyllum demersum of Wular Lake, a Ramsar Site in Kashmir Himalaya were analysed during March- November 2011. The content of organic matter and organic carbon for Nymphoides peltatum were 114.1 g m-2 and 53.1 g C m-2 and Ceratophyllum demersum were 57.0 g m-2 and 26.4 g C m-2. Chlorophyll A (Chl a) and chlorophyll A+B (Chl a+b) pigments ranged from 1.75 mg g-1 (Chl a) and 2.1mg g-1 (Chl a+b) in Nymphoides peltatum to 4.41 mg g-1 (Chl a) and 5.69 mg g-1 (Chl a+b) in Ceratophyllum demersum. In full leaf out, the latter aquatic plants exceeded 15-20% coverage of the open water surface.Ceratophyllum demersum and Nymphoides peltatum achieved maximum growth in June and August respectively, but significant differences in their growth dynamics was observed. At the end of the vegetation period, these plants sink to the bottom and decompose.
Optimization of a Groundwater Monitoring Network for a Sustainable Development of the Maheshwaram Catchment, India
Aadil Nabi,Adrian H. Gallardo,Shakeel Ahmed
Sustainability , 2011, DOI: 10.3390/su3020396
Abstract: Groundwater is one of the most valuable resources for drinking water and irrigation in the Maheshwaram Catchment, Central India, where most of the local population depends on it for agricultural activities. An increasing demand for irrigation and the growing concern about potential water contamination makes imperative the implementation of a systematic groundwater-quality monitoring program in the region. Nonetheless, limited funding and resources emphasize the need to achieve a representative but cost-effective sampling strategy. In this context, field observations were combined with a geostatistical analysis to define an optimized monitoring network able to provide sufficient and non-redundant information on key hydrochemical parameters. A factor analysis was used to evaluate the interrelationship among variables, and permitted to reduce the original dataset into a new configuration of monitoring points still able to capture the spatial variability in the groundwater quality of the basin. The approach is useful to maximize data collection and contributes to better manage the allocation of resources under budget constrains.
Investigation on Numerical Modeling of Water Vapour Condensation from a Flue Gas with High COR2R Content  [PDF]
Hamid Nabati
Energy and Power Engineering (EPE) , 2011, DOI: 10.4236/epe.2011.32023
Abstract: In this paper, condensation of water vapor from a mixture of COR2R/HR2RO is studied numerically. To simplify the study and focus on the physical model, a simple vertical plate was chosen. Two condensation models are developed and numerical approach is considered to implement these models. The main objective in the cur-rent paper was to study the capability of numerical modeling in prediction of complex process. Results showed that developed condensation models in combination with numerical approach can predict the trends in condensation behavior of binary mixture very well. Results from this study can be developed further to be used in design of condensers which are suitable for oxy-fuel power plants.
Optimal Node Scheduling for Desired Percentage of Coverage in Wireless Sensor Networks  [PDF]
Hamid Khosravi
Wireless Sensor Network (WSN) , 2012, DOI: 10.4236/wsn.2012.45018
Abstract: Recent developments in wireless communication and embedded computing technologies have led to the advent of wireless sensor network technology. Hundreds of thousands of these micro sensors can be deployed in many areas including health, environment and battlefield in order to monitor the domain with desired level of accuracy. When wireless sensors are deployed in an area, the lifetime of the network should last as long as possible according to the original amount of energy. Therefore, reducing energy consumption in WSNs is of primary concern. We have proposed a node scheduling solution that solves the coverage and connectivity problem in sensor networks in an integrated manner. In this way we will divide network life time to finite number of rounds and in each round we will generate a coverage bitmap of sensors of the domain and based on this bitmap it will decided which sensors remain active or go to sleep. We will check the connection of the sensor network by using Laplacian of adjancy graph of active nodes in each round. Also the network will be capable of producing desired percentage of coverage by using coverage bitmap. We will define the connected coverage problem as an optimization problem and we will seek a solution for the problem by using Genetic Algorithm optimization method.
Ethyl (3E)-3-[2-(4-bromophenylsulfonyl)hydrazin-1-ylidene]butanoate

Acta Crystallographica Section E , 2012, DOI: 10.1107/s1600536812019265
Abstract: The asymmetric unit of title compound, C12H15BrN2O4S, contains two molecules (A and B), with slightly different conformations: the bromophenyl rings and the SO2 planes of the sulfonyl groups are oriented at dihedral angles of 50.2 (2) (molecule A) and 58.24 (7)° (molecule B), and the ethyl acetate groups make dihedral angles of 63.99 (19)° (A) and 65.35 (16)° (B) with their bromophenyl groups. In the crystal, both molecules exist as inversion dimers linked by pairs of N—H...O hydrogen bonds, which generate R22(14) loops. The dimers are linked by C—H...O interactions.
2-[(2-Aminophenyl)sulfanyl]-N-(4-methoxyphenyl)acetamide
Shahzad Murtaza,M. Nawaz Tahir,Javaria Tariq,Aadil Abbas
Acta Crystallographica Section E , 2012, DOI: 10.1107/s1600536812024178
Abstract: In the title compound, C15H16N2O2S, the dihedral angle between the 4-methoxyaniline and 2-aminobenzenethiole fragments is 35.60 (9)°. A short intramolecular N—H...S contact leads to an S(5) ring. In the crystal, molecules are consolidated in the form of polymeric chains along [010] as a result of N—H...O hydrogen bonds, which generate R32(18) and R43(22) loops. The polymeric chains are interlinked through C—H...O interaction and complete R22(8) ring motifs.

Abstract: The aims of this research were (1) to assess the sustainability of the marine sanctuary program in the COREMAP site phase II Raja Ampat; and (2) to find out the parameters which affect the sustainability aspects marine sanctuary program in the COREMAP site phase II Raja Ampat. This research had been conducted in Raja Ampat-West Papua by using survey method and respondents determined by purposive sampling method. The collected data had been analyzed by Analytic Hierarchy Process, or AHP. The results indicated that (1) the sustainability of marine sanctuary program in the COREMAP site phase II Raja Ampat will go on, because the strong indications showed that the comprehensive sustainable value were 2,178 (high category), (2) from 22 evaluated villages, 15 villages (68,2%) have sustainability value by high category and 7 villages (31,8 %) have sustainability value by moderate category (i.e: Villages of Saonek, Yenbeser, Kurkapa, Bianci, Selpele, Yensawai, and Arefi).
Using of the Generalized Special Relativity in Deriving the Equation of the Gravitational Red-Shift  [PDF]
Mahmoud Hamid Mahmoud Hilo
Journal of Modern Physics (JMP) , 2011, DOI: 10.4236/jmp.2011.25045
Abstract: In this work we present a study of a new method to prove the equation of the gravitational red shift of spec-tral lines. That’s according to the generalized special relativity theory. The equation of the gravitational red shift of spectral lines has been studied in many different works, using different methods depending on the Newtonian mechanics, and other theories. Although attention was drawn to the fact that the well-known ex-pression of the gravitational Red-Shift of spectral lines may be derived with no recourse to the general rela-tivity theory! In this study a unique derivation has been done using the Generalized Special Relativity (GSR) and the same result obtained.
Improving Project Change Management Using Leadership Spirit  [PDF]
Hamid Shafaei Bejestani
iBusiness (IB) , 2011, DOI: 10.4236/ib.2011.33040
Abstract: Projects seldom run exactly according to their plans due to changes. However, project deliverables must be provided on-time and on-budget, either by rejecting changes or by converting their threats to opportunities. To achieve this, project team should be kept ready to control changes. In this issue, leadership is an effective spirit for a project manager to keep his/her project team in its best condition for rejecting changes, or getting back on track, or earning benefits from changes. A project leader is more successful than a project manager in change management.
