Accountability for mass violence : examining the state's record

This detailed study aims to map, understand and evaluate how effectively the State in free India has secured justice for victims of mass violence. It focuses on the access of victims to protection, justice and reparation after communal violence. By excavating the State’s own records on documented events of mass violence, the report confirms that the State has largely failed to prosecute perpetrators, to account for its own failures, to compensate victims, and to inform citizens. While immediate relief and monetary compensation is not sufficient, it is necessary, and measures in this regard demand close scrutiny

An SU(3) model for octet baryon and meson fragmentation

The production of the octet of baryons and mesons in e^+ e^- collisions is analysed, based on considerations of SU(3) symmetry and a simple model for SU(3) symmetry breaking in fragmentation functions. All fragmentation functions, D_q^h(x, Q^2), describing the fragmentation of quarks into a member of the baryon octet (and similarly for fragmentation into members of the meson octet) are expressed in terms of three SU(3) symmetric functions, \alpha(x, Q^2), \beta(x, Q^2), and \gamma(x, Q^2). With the introduction of an SU(3) breaking parameter, \lambda, the model is successful in describing hadroproduction data at the Z pole. The fragmentation functions are then evolved using leading order evolution equations and good fits to currently available data at 34 GeV and at 161 GeV are obtained.Comment: 24 pages LaTeX file including 11 postscript figure file

Evaluation of the efficacy of LASER, desensitizing agents, and their combined effect on dentinal hypersensitivity in bicuspids: In Vitro study

Aim: This study aimed to know the potential of diode light amplification by stimulated emission of radiation (LASER) and desensitizing agents on blocking the dentinal tubules, which may further help in reducing the most common dental problem named dentinal hypersensitivity (DH). Materials and Methods: Sixty human permanent bicuspids were selected, and preparation was performed in the cervical region measuring 2.5 mm × 2.5 mm × 2.5 mm, followed by acid etching for 15 seconds. These are then divided according to the groups mentioned: group 1—nano-hydroxyapatite (HA) was applied for 15 minutes; group 2—biosilicate was applied for 15 minutes; group 3—diode LASER application was performed twice for 60 seconds in noncontact mode; group 4—nano-HA plus diode LASER application; and group 5—biosilicate plus diode LASER application. The same procedure was followed on the 1st, 7th, and 14th days and then rinsed and stored in artificial saliva, and the saliva was changed every 24 hours. The dentinal tubular occlusion was observed under a scanning electron microscope (SEM) after the 14th day. Result: The maximum dentinal tubular occlusion was observed in group 4, where nano-HA and diode LASER application was performed. Conclusion: All the investigated treatment groups have promising occluding potential, but the maximum was found in group 4 >group 5 >group 3 >group 1 >group 2. LASER plus desensitizing together prove to be potent and effective in reducing dentinal tubular diameter
