Journal of Rural Development, Vol 29, No 4 (2010), Pagination: 479-492Abstract
The present paper is based on facts derived from empirical investigation of the two tribal villages namely, Argandi and Bagmundi in Barhait and Borio blocks of Sahibganj district, which represent low density forest regions in Jharkhand. It highlights the nature and pattern of rural development in the region as a result of Joint Forest Management (JFM). The paper is divided into three sections. Section I is introductory which conceptualises the notion of Joint Forest Management and Rural Development. It also includes the objectives and guidelines of JFM in India. Section II deals with universe and sample of the study, which describes the demographic and socio- economic profile of the region as well as the respondents. Section III presents the empirical findings. Facts include the nature of employment generation from forest activities, a comparative account of management practices in pre-JFM and post-JFM periods, composition of income from forest resources, overall ecological, economic and social impacts of JFM in the region. It also covers the strengths, weaknesses, opportunities and threats of JFM in the concerned area.Full Text

The dislocation of the mandibular condyle / condyles occurs most commonly in an anterior direction due to trauma. This is a known fact as due to pull of lateral pterygoid muscle. On the contrary, posterior, superior, or lateral dislocations of the intact mandibular condyle occur rarely, and very few such cases have been reported in the English language literature. The rarity of these dislocations can be attributed to the varying anatomy of the condyle, the direction of pull of muscles attached to the condyle and low incidence of skull base fractures from an indirect blow. A case of bilateral supero-lateral dislocation of the condyle associated with a symphyseal fracture is presented. We discuss the dynamics, diagnostic features and clinical management of such dislocations with extensive review of literature.Keywords

Low altitude coastal lakes along the Antarctic margin often contain both marine and lacustrine sediments as a result of relative sea level changes due to deglaciation. The sediments also record changes in regional climate. A sediment core from a coastal lake in Larsemann Hills, East Antarctica, viz. Stepped Lake (Heart Lake), records distinct changes in C, N, C/Natomic ratio, δ 13COM, δ 15NOM and diatom abundance during the mid-Holocene (8.3 to 4.6 kyr BP). Lower values (Corg ~1%; C/N 8, 13COM ~ –18‰) during the early Holocene (8.3–4 kyr BP) are consistent with marine conditions, while higher values [Corg 6%; C/N 12; 13COM ~ –12‰) suggest a shift to lacustrine conditions (5.5–4.6 kyr BP). The diatom community shows similar shift with the major part of Holocene (8.3– 5.5 kyr BP) dominated by sea-ice and open-ocean diatoms while the core-top sections (5.5–4.6 kyr BP) transitions to lacustrine diatoms (Stauroforma inermis). These observations confirm that the basin was marine, and later became isolated as a result of postglacial isostatic uplift after 4.7 kyr BP.Keywords

Denitrification in the Arabian Sea is a vital process that provides feedback to global warming by releasing nitrous oxide to the atmosphere. Therefore, it is important to understand the evolution and dynamics of denitrification on different timescales. We present here the denitrification variability spanning the past ~600 thousand years (kyr). It is based on ~300 new measurements from IODP 355 Expedition. We compared the existing records of denitrification to understand the factors influencing the denitrification on various timescales. On glacial–interglacial timescale, we find stronger denitrification during interglacial and weaker denitrification during glacial periods. During the Holocene, we observe declining denitrification in the Western Arabian Sea in response to the reduced monsoon-induced productivity but find increasing denitrification in the Northeastern Arabian Sea due to reduced ventilation.Keywords
