Immmunobiolotical Observations On Avian Influenza Virus Types H7 And H,

by Shahid Iqbal | Prof. Dr. Muhammad Akram Muneer | Dr. Mansur-ud-Din Ahmad | Faculty of Veterinary Sciences.

Material type: book Book; Format: print ; Literary form: drama Publisher: 2007Dissertation note: The present study was designed to 'find the prevalence of Avian Influenza disease in and around Lahore in commercial and household poultry. A total of 1000 blood and 500 cloacal swabs were collected from Broilers, Broiler-Breeders, Ducks, Pigeons, Sparrows, Quails and Desi Chickens. The blood samples from all the flocks showed non-significant titers while vaccinated flocks showed protective titers. All the cloacal swabs were negative for virus isolation. The final conclusions from this study were the following.i.e. - Avian influenza caused by H7 & H9 type is not prevalent in broiler and broiler breeders in and around Lahore. - The vaccinated poultry flocks showed higher titers of antibodies as compared to non-vaccinated flocks which means that vaccine can play a vital role in protection of bird from H7 & H9.

Blood Spatter Classification As A Function Of Blood Droplet Dynamics And Their Forensic Implications

by Shahid Iqbal | Mr. Akhtar Ali | Dr. Muhammad | Dr. Muhammad Tayyab.

Material type: book Book; Format: print Publisher: 2013Dissertation note: A thoroughconsideration of blood dynamics and stain creation is avital necessityto the clarification of distinct bloodstain and the spatter patterns at the crime scene. In addition the results of experimental work including studies of falling and impacting blood droplets have been presented. The magnitude of blood stains and the amount of droppers and needles round the stain fringe relays on droplet impact velocity and droplet diameter. It is not unusual to find bloodstain patterns in a violent encounter and through proper interpretation they can provide very critical details about such an event. Accurate calculations and digital photography may estimate the release height of passive droplets, the characteristics of release surface and the forces involved in bloodshed.The spattered blood pattern is used routinely in crime scene for investigators/death scene investigators to evaluate blood spattering and blood droplet impact velocity. Examination could determine the maximum resolution of bloody spots. Four different forms of stains were produced and human blood was used with heparin as an anti-coagulant (Kargeret al.1998). The blood volumes usedwere: 10 l, 5 l, 1 l, 0.5 l, 0.25 land0.1 l. Pipette (Eppendorf) and precision syringe were used for measuring and releasing the blood spattering. Blood droplets were allowed to fall freely by hand by pressing the needle of the syringe very slowly so that drops separated from the tip of a stainless steel hypodermic needle at their own mass.Respectively,all volumeswererepeated for consecutive five times to create four forms of contact stains and spatter stains on various surfaces used in the study.The resulting stains were examined with and at the end were photographed through digital camera. The results were interpreted by applying Regression coefficient relationone way Anova and two ways Anova which showed significance statistically.It will aid the crime investigation agencies to explore the importance of blood spatter analysis in crime/ death scene investigationand to estimate the creditability of reportsdelivered by the observer, prey or a doubtful.
