  The Siwalik formations of northern Pakistan consist of (fluvial) deposits of ancient rivers that were formed from the early Miocene up to the late Pliocene. The tertiary continental deposits of the Siwaliks are highly fossiliferous with a diverse array of terrestrial and freshwater vertebrates in which ruminants are fairly abundant. The rich Siwalik fossil record presents a detailed history of the prehistoric mammals of the Indian Subcontinent. In this research it was analyzed individual well-sampled sites to study the past ruminant community. The Siwalik fossil record becomes increasingly informative for diverse research questions in paleobiology as a result of its growing and robust data set. The fossils from Pakistan may also document the first appearance and subsequent radiation of giraffes and bovids, two groups that dominate the late neogene (tertiary) as well as the modern herbivore faunas. Throughout the Siwalik formations, the ruminants are by far the most abundant mammal group. The number of ruminant species, as recorded in the tertiary hills of the Siwaliks is clearly greater than that observed in most ecosystems today, which probably indicates overall greater species richness than is typically present. Today, the ruminants constitute the largest group of ungulates, with more than 190 species and its distribution is widespread in all continents except Australia and Antarctica.

  Brevibacterium flavum maintained at 7.0 pH level and at 37 °C temperature, gives maximum production of lysine. When the organism was given UV shocks for 30 minutes, gave the lysine in maximum quality. Water substrate ratio, addition of molasses, addition of corn steep liquor were optimized. At 40% water substrate ratio, addition of 4% corn steep liquor and 4% molasses bacteria was most efficient in the production of lysine. The biomass thus produced contained 32.8% crude protein, 20.87% true protein, 34% ash and 1.1% fat contents on the basis of dry matter. There was no increase or decrease in ether extract and crude fiber. The biomass produced was analyzed by three-enzyme method. Its digestibility was 85.69% in single cell protein biomass. Amino acid profile showed that lysine production was 21.48mg/g on the basis of protein.

  The physico-chemistry of two fresh water fish ponds was investigated for a duration of 255 days to see the affect of two different doses of inorganic fertilizers (urea and SSP). Both the ponds were treated with fertilizers at the basis of 0.08 and 0.1 % N of body weight of fish daily. Statistically, ammonia, nitrates and biomass were significant in both the treatments. But, temperature, light penetration, pH, electrical conductivity, dissolved oxygen, total alkalinity and total hardness were non-significant. Environmental changes were observed in the pond ecosystem when fertilized with different doses of inorganic fertilizers.

  Peroxidase from tomato was extracted and partially purified by means of ammonium sulphate [(NH4)2SO4] precipitation technique and ion exchange chromatography. The crude extract having the specific activity of 0.239U mg-1 was subjected to (NH4)2SO4 precipitation technique for partial purification of peroxidase. The specific activity of (NH4)2SO4 precipitated enzyme was 0.546U mg-1 with protein contents of 0.412mg ml-1. After ion exchange chromatography through DEAE-Cellulose columns, the specific activity was 11.844U mg-1 and the protein contents were decreased to 0.0358mg ml-1 showing that unnecessary proteins have been eliminated. Finally, partially purified enzyme was subjected to SDS-Electrophoresis for confirming the purification. So it was concluded that crude and partially purified enzymes from tomato possess an appreciable enzyme activity.

  A well preserved first right lower molar from the Tertiary rocks of Pakistan is described from Padhri (Middle Siwaliks) District Jhelum, the Punjab province, Pakistan. It essentially differs from the known material of the genus Sivapanthera both in morphology and size. The name Sivapathera padhriensis is being proposed to this new addition.

  Pseudomonas aeruginosa, a plant growth-promoting rhizobacterium and Memnoniella echinata, a fungal antagonist used separately or in combination in soil amended with neem cake and/or chemical fertilizers significantly suppressed root infecting fungi viz., Macrophomina phaseolina, Fusarium solani and Rhizoctonia solani and the root-knot nematode Meloidogyne javanica in mungbean. Soil amendment increased biocontrol and growth promoting potential of P. aeruginosa and M. echinata.

  The seeding rates were 100 and 150 kg ha–1 while the nitrogen levels comprised 100, 150 and 200 kg ha–1 with five split application treatments viz. full at sowing, full with first irrigation, half at sowing and half with first irrigation, two third at sowing+one third with first irrigation and one third at sowing+One third with first irrigation+one third with second irrigation along with a basic dose of 100 kg ha–1 each of P and K applied at sowing. The crop was planted on December 19. The highest grain yield of 3585 kg ha–1 was obtained from plots given nitrogen full at sowing at 150 kg ha–1 followed by 3334 kg ha–1 in plots given nitrogen in two splits i.e., two third at sowing and one third with first irrigation. However, higher seeding rate (150 kg ha–1 ) tended to increase grain yield ha–1 with a nitrogen rate of 150 kg ha–1. By contrast, grain protein contents were the highest (12.26%) in crop fertilized with 150 kg ha–1 full at sowing and seeded at 100 kg ha–1.
