Comment: Monitoring Networked Applications With Incremental Quantile Estimation
Our comments are in two parts. First, we make some observations regarding the
methodology in Chambers et al. [arXiv:0708.0302]. Second, we briefly describe
another interesting network monitoring problem that arises in the context of
assessing quality of service, such as loss rates and delay distributions, in
packet-switched networks.Comment: Published at http://dx.doi.org/10.1214/088342306000000600 in the

SOME FORENSIC ASPECTS OF BALLISTIC IMAGING
Analysis of ballistics evidence (spent cartridge casings and bullets) has been a staple of forensic criminal investigation for almost a century. Computer-assisted databases of images of ballistics evidence have been used since the mid-1980s to help search for potential matches between pieces of evidence. In this article, we draw on the 2008 National Research Council Report Ballistic Imaging to assess the state of ballistic imaging technology. In particular, we discuss the feasibility of creating a national reference ballistic imaging database (RBID) from test-fires of all newly manufactured or imported firearms. A national RBID might aid in using crime scene ballistic evidence to generate investigative leads to a crime gun’s point of sale. We conclude that a national RBID is not feasible at this time, primarily because existing imaging methodologies have insufficient discriminatory power. We also examine the emerging technology of micro- stamping for forensic identification purposes: etching a known identifier on firearm or ammunition parts so that they can be directly read and recovered from crime scene evidence. Microstamping could provide a stronger basis for identification based on ballistic evidence than the status quo, but substantial further research is needed to thoroughly assess its practical viability
Introduction to Exotics and Trans-Boundary Movement of Aquatic Organisms: Policy Requirements and Relevance to Indian Aquaculture in the Post-WTO Scenario
Aquaculture is one of the fastest growing industries with an annual growth rate of more than 11 per cent for the past 10 years, producing about 16 per cent of the world supply of animal protein, primarily for human consumption. FAO (2007) has estimated the production from aquaculture at 47.8 million tonnes in 2005 and the global aquaculture production in comparison has overtaken the global production of meat from bovine, ovine, porcine and poultry. Global aquaculture production has jumped from a mere 3.9 per cent of the food produced in 1970 to an impressive 47 per cent in 2006, which indicates a 10 per cent per annum growth. The Indian aquaculture sector led by shrimp and carp farming has recorded an impressive growth during the past decades, raising itself to the status of an industry and a major source of foreign exchange to the country to the tune of @15000 crores/year. The strength of Indian aquaculture lies in (a) large water bodies suitable for aquaculture, (b) tropical Climate, (c) species diversity and (d) availability of cheap labour. While the weakness include (a) unregulated development, (b) disease problems and (c) lack of scientific approaches and (d) non-compliance with guidelines and regulations
Crystallization and preliminary X-ray studies of snake gourd lectin: homology with type II ribosome-inactivating proteins
Diseases in Ornamental Fishes
Any impairment that interferes with the performance of normal funcrions including responses to environmental factors, roxicants, dimare, nutrition, infectious agents etc can be termed a disease. Diseases can be caused by a variety of factors, the most important being pathogens. Other factors contributing cowards the development of disease conditions include stress, environmental/water qualiry, physical agents, nutritional imbalance, toxins etc. or a combination of these
Evolution of suitable trawl nets for medium size trawlers - 1: Comparative fishing efficiency between 32 m bulged belly, long wing and four panel trawls
Comparative studies of the efficiency of 32 m bulged belly, long wing and four panel trawls have shown that the bulged belly trawl to be superior to the other nets in catching bottom fishes and column fishes. 40% of the bottom fishes and 48% of the column fishes were caught by the bulged belly trawl. However, for prawn catch, the long wing trawl appears to be better as it landed 52% of the total prawn catch of the three nets. Bulged belly trawl was found to be next only to long wing trawl in this respect

ABSTRACT: We wished to evaluate the pulmonary defence capacity against common
bacterial infections in patients with pulmonary tuberculosis.
Bactericidal activity against Staphylococcus aureus of bronchoalveolar lavage fluids
(cell-free supernatants) of patients with active (n=13) and inactive pulmonary
tuberculosis (n=8), and normal individuals (n=6), were studied.
The 2 and 4 h bactericidal activities were higher than the 0 h activity in lavage
fluids of healthy subjects and patients with inactive pulmonary tuberculosis. Active
tuberculous lavage fluids were equally competent in their bactericidal activity against
S. aureus at 0 and 2 h, but a reduced S. aureus hilling was seen at 4 h of incubation.
Estimation of total phospholipid levels revealed no significant difference
between the various lavage fluids. This reduced hilling of S. aureus showed a relationship
with the cellular components (lymphocytes and macrophages) of active
tuberculous lavage fluids. A reduced hilling was associated with no lymphocytic
alveolitis, and an increased hilling with lymphocytic alveolitis.
This study suggests that alveolar lining material of patients with active pulmonary
tuberculosis has less bactericidal activity against bacterial infections, such as S.
aureus
