In the present investigation, vitellogenesis during ovarian development in the freshwater prawn Macrobrachium rosenbergii was assessed. Ovarian development was classified into five stages based on size, colour and texture of ovary. Interestingly, histological results clearly indicate that the oocyte development gradually increased from stages I to V based on the yolk material accumulation. Besi...

This paper evaluates the preimage resistance of the Tiger hash function. We will propose a pseudo-preimage attack on its compression function up to 23 steps with a complexity of 2, which can be converted to a preimage attack on 23-step Tiger hash function with a complexity of 2. The memory requirement of these attacks is 2 words. Our pseudo-preimage attack on the Tiger compression function adop...

A study was conducted to appraise the effect of different stocking densities on three male morphotypes named blue claw (BC), orange claw (OC) and small male (SM) at harvest  in all-male culture and to assess the growth performance of  BC, OC and SM in each isolated culture. Trials involving three stocking densities of all-male prawn viz., 20, 30 and 40 juvenile m-2 were carried out in replicate...

Tiger is a cryptographic hash function proposed by Anderson and Biham in 1996 and produces a 192-bit hash value. Recently, weaknesses have been shown in round-reduced variants of the Tiger hash function. Collision attacks have been presented for Tiger reduced to 16 and 19 (out of 24) rounds at FSE 2006 and Indocrypt 2006. Furthermore, Mendel and Rijmen presented a 1-bit pseudo-near-collision fo...

The tiger is one of the most iconic extant animals, and its origin and evolution have been intensely debated. Fossils attributable to extant pantherine species-lineages are less than 2 MYA and the earliest tiger fossils are from the Calabrian, Lower Pleistocene. Molecular studies predict a much younger age for the divergence of modern tiger subspecies at <100 KYA, although their cranial morphol...

Conservation investment, particularly for charismatic and wide-ranging large mammal species, needs to be evidence-based. Despite the prevalence of this theme within the literature, examples of robust data being generated to guide conservation policy and funding decisions are rare. We present the first published case-study of tiger conservation in Indochina, from a site where an evidence-based a...

BACKGROUND Cyperus esculentus tubers (tiger nut) are one of the ancient food sources known to humanity. It is traditionally used in the Middle East to stimulate sexual arousal in men. However, there has been no scientific evidence about its assumed aphrodisiac properties. This study aimed to investigate the influence of tiger nut on the copulatory behavior of sexually active male rats. METHOD...

How morphology changes with size can have profound effects on the life history and ecology of an animal. For apex predators that can impact higher level ecosystem processes, such changes may have consequences for other species. Tiger sharks (Galeocerdo cuvier) are an apex predator in tropical seas, and, as adults, are highly migratory. However, little is known about ontogenetic changes in their...
