Implication of Traditional Ecological Knowledge on Forest Resource Management
Dhruba Laudari
Himalayan Journal of Sociology and Anthropology , 2010, DOI: 10.3126/hjsa.v4i0.4669
Abstract: The primary approaches within contemporary ecological anthropology are cultural ecology, historical ecology, political ecology and spiritual ecology. The cumulative approach developed on by fusing these approaches is applied dimension of ecological anthropology known as environmental anthropology. Human populations have ongoing contact and impact upon the land, climate, plant and animal species in their vicinities and these elements of their environment have reciprocal impacts on humans. The theme of traditional ecological knowledge is important for the consideration of a broad range of question related to nature-environment relations. Different groups of people in various parts of the world perceive and interact with nature differently, and have different traditions of environmental knowledge. Their perceptions and knowledge are partly shaped by their values, worldview and environmental ethics. In the exploration of environmental ethics and religion toward an ecologically sustainable society, indigenous peoples and traditional ecological knowledge have attracted considerable attention from both scholars and popular movements. The lesson from this ield study, under the theoretical outline of cultural and human ecology includes the importance of cultural conservation of forest resources, adaptive management, uses of traditional ecological knowledge and development of religious/spiritual conservation ethic. This may contribute to the development of an interdisciplinary conservation science with a more sophisticated understanding of social-ecological interactions. The indings thus could be used for formulating better policies for sustainable management of forest/natural resources.

Planning and Performance: The Effect of Form Focused Guided Planning on Learner Performance
Suman Laudari
Journal of NELTA , 2013, DOI: 10.3126/nelta.v18i1-2.10333
Abstract: Task-based language teaching (TBLT) has been a dominant approach in the field of ELT for some time now. However, it has complexities regarding its use in a foreign language context. It is said that focusing only on interaction may not be enough in guiding learners to use language correctly, so learners need exposure to grammar rules, and teachers presume that TBLT does not allow it. But, learners’ attention could be directed to the grammar forms during task planning to facilitate noticing of linguistic code. To this end, this small-scale study collects discourse data from an adult EFL learner to evaluate whether guiding learners’ attention to grammar during pre-task planning is of any help. The study concludes that guiding learners’ attention facilitates in producing more accurate and complex discourse than leaving learners on their own during the task planning.

Journal of College of Medical Sciences-Nepal , 2011, DOI: 10.3126/jcmsn.v7i4.6736
Abstract: Organophosphorus (OP) compound poisoning is a medical emergency. It is important to know its nature, clinical presentation, severity and outcome in order to take up appropriate measures including proper planning, treatment and prevention. This study was aimed to assess the clinical profile of organophosphorus poisoning. This is a prospective hospital based study conducted at CMS-T.H., Bharatpur, Nepal. The study included 111 patients of organophosphorus poisoning during the period November 2008 to July 2011. The incidence was commoner in females than males with female:male ratio being 1.47:1. Majority of the patients(58.56%) belonged to the age group 16 to 30 years with female predominance(2.25:1). Modes of poisoning were suicidal in the majority (94.59%), accidental in 4.50%. and homicidal in 0.90%. Psychiatric problems were the major precipitating factors. Majority of patients(62.16%) had moderate poisoning (POP scale: 4-7).On admission, dyselectrolytemia and respiratory failure were found in 74.77% and 21.62% respectively.8 patients expired (7.69%). Large amount of OP poison ingestion (>40ml) and increased severity of poisoning (POP scale) were found to have statistical significance with the rate of mortality.

Influence of Benzoate on Substituent Benzoic Acids with Implications on Spectroscopic Studies through Inter Molecular Hydrogen Bonding  [PDF]
Ravi Shankar Kumar
Materials Sciences and Applications (MSA) , 2011, DOI: 10.4236/msa.2011.26068
Abstract: Comprehensive study on the homologous series of compounds in the form A-R- HHB are synthesized with central rigid core as benzoic acids together with substituent’s alkoxy (A) and alkyl (R) group of equal chain lengths from 5 to 10 are connected to hexyl-p-hydroxy benzoate (HHB). These complexes form supramolecular structures by self assembling process due to intermolecular hydrogen bonding. The formation is analyzed with techniques involving polarizing optical microscope, infrared spectroscopy, proton NMR spectroscopy and powdered X-ray diffraction. Results suggest that complexes arise from both A and R groups exhibit enantiotropic layered texture of crystal G phase observed by microscopic studies due to flexible nature of mesogenics. The conversion of free to molecular complexes is determined with variations in spectral shifts between its terminal groups COOH and OH of molecules involving inter molecular hydrogen bonding and its bonding index by FTIR spectra. The changes in structure and dynamics due to hydrogen bonding in complexes are convinced by proton NMR spectra with chemical shifts in specified range. The defects in crystal structure responsible for enantiotropic phenomena are analyzed by powdered X ray diffraction.

Light-Front Hamiltonian and Path Integral Formulations of the Conformally Gauge-Fixed Polyakov D1 Brane Action  [PDF]
Usha Kulshreshtha, Daya Shankar Kulshreshtha
Journal of Modern Physics (JMP) , 2011, DOI: 10.4236/jmp.2011.25041
Abstract: In a recent paper we have studied the Hamiltonian and path integral quantizations of the conformally gauge-fixed Polyakov D1 brane action in the instant-form of dynamics using the equal world-sheet time framework on the hyperplanes defined by the world- sheet time . In the present work we quantize the same theory in the equal light-cone world-sheet time framework, on the hyperplanes of the light-front defined by the light-cone world-sheet time , using the standard constraint quantization techniques in the Hamiltonian and path integral formulations. The light-front theory is seen to be a constrained system in the sense of Dirac, which is in contrast to the corresponding case of the instant-form theory, where the theory remains unconstrained in the sense of Dirac. The light-front theory is seen to possess a set of twenty six primary second-class contraints. In the present work Hamiltonian and path integral quantizations of this theory are studied on the light-front.
Light-Front Hamiltonian and Path Integral Formulations of the Conformally Gauge-Fixed Polyakov D1 Brane Action with a Scalar Dilation Field  [PDF]
Usha Kulshreshtha, Daya Shankar Kulshreshtha
Journal of Modern Physics (JMP) , 2011, DOI: 10.4236/jmp.2011.28097
Abstract: Recently we have studied the instant-form quantization (IFQ) of the conformally gauge-fixed Polyakov D1 brane action with and without a scalar dilaton field using the Hamiltonian and path integral formulations in the equal world-sheet time framework on the hyperplanes defined by the world- sheet time σ0=τ=constant . The light-front quantization (LFQ) of this theory without a scalar dilaton field has also been studied by us recently. In the present work we study the LFQ of this theory in the equal light-cone world-sheet time framework, on the hyperplanes of the light-front defined by the light-cone world-sheet time σ+=τ+σ=constant , using the Hamiltonian and path integral formulations. The light-front theory is seen to be a constrained system in the sense of Dirac. The light-front theory is seen to possess a set of twenty seven primary second-class contraints. In the present work Hamiltonian and path integral quantizations of this theory are studied on the light-front.
