A Study on Causes of Condemnation of Carcass and Organs at Shah Alam Abattoir

A two-week study of the causes of condemnation at Shah Alam abattoir was conducted. In the bovine species, liver and lungs w.ere the main organs condemned due to fluke infestation. and emphysema respectively. Ninety-five percent of pig lungs were condemned because of back bleeding, while in sheep caseous lymphadenitis was the major cause of organ condemnedtion affectingg mainly the lungs and lymph nodes. No total carcass condemnation was observed in any species during the study perio

Ultrastructural pathology of the upper respiratory tract of rabbits experimentally infected with Pasteurella multocida A:3

Twenty-four 8 to 9 week-old Pasteurella multocida-free rabbits were divided into three equal groups, the first group was pretreated with hydrocortisone and inoculated intranasally with pasteurella multocida serotype A:3. The second group was inoculated intranasally with P. multocida without hydrocortisone treatment. The third group was inoculated with phosphate buffered saline only and used as a control group. Pasteurella multocida was isolated from the nasal cavity of all infected rabbits in group 1 and 2 and from the trachea of seven rabbits in group 1 and five rabbits in group 2. This study was conducted to observe the ultrastructural changes of the upper respiratory tract of hydrocortisone treated and non-treated rabbits infected with P. multocida serotype A:3. The ultrastructural changes detected in infected rabbits were ciliary destruction and deciliation of the ciliated epithelial cells, cellular swelling, goblet cell hyperplasia and endothelial cell damage. Pasteurella multocida was observed attached to the degenerated cilia,microvilli and mucus. Pasteurella multocida infection was associated with inflammatory responses, which may have caused tissue damage. It is possible that hydrocortisone modulates the severity of infection as an immune suppressor and an inhibitor of goblet cell secretion

Object's shadow removal with removal validation

We introduce in this paper, a shadow detection and removal method for moving objects especially for humans and vehicles. An effective method is presented for detecting and removing shadows from foreground figures. We assume that the foreground figures have been extracted from the input image by some background subtraction method. A figure may contain only one moving object with or without shadow. The homogeneity property of shadows is explored in a novel way for shadow detection and image division technique is used. The process is followed by filtering, removal, boundary removal and removal validation

STUDY OF PROBIOTICS ON THE SEED PRODUCTION OF BLACK TIGER SHRIMP Penaeus monodon

Currently, antibiotics are widely used in shrimp hatcheries to control bacterial infections. Appearance of antibiotic resistant pathogens and restriction on the use of antibiotics have led to the development of alternatives to antibiotics in hatchery systems. In light of this, an attempt was undertaken to investigate the effects of probiotics on the larval rearing of Penaeus monodon, compared with control tanks (without probiotics). The results showed that several issues significantly improved with administering probiotics in the experimental tanks compared with the tanks without probiotics. For example, the concentration of ammonia was estimated to be 1.25 mg/L that was less than half of what was measured in the control tanks. The size variation was observed more in the control tanks than in the experimental tanks. Moreover, the muscle gut ratio of PL15 was about 85 to 92% in the probiotic treated tank and 70 to 80% in the control tank during the eight cycles of production. The fouling organisms were more in the control tank compared to the experimental tanks. The average length of PL15 was maximum when reared in the experimental tanks compared to the control tanks. The final survival rate of PL15 from the control and experimental tank was 35 and 52%, respectively. The present investigation indicated that probiotics played an important role in the growth, survival and health status of P. monodon larvae

Management of oesophageal foreign bodies

AbstractObjectiveThe aim of the study was to evaluate the management of foreign bodies in the oesophagus and to determine the association with socioeconomic status.MethodsThis cross-sectional analytical study was carried out in the Department of Ear, Nose and Throat and head and neck surgery of Bahawal Victoria Hospital affiliated with Quaid-i-Azam Medical College, Bahawalpur, Pakistan, between December 2012 and May 2013. The medical records of 34 consecutive cases of foreign body ingestion were searched, and the data were recorded on a questionnaire prepared for this purpose.ResultsThe average age of the patients was 10.38 years; 29 cases (85.2%) were in children under 12 years. There were 18 females (52.9%) and 16 males (47.1%). Thirty patients (88%) presented with a history of dysphagia, and 25 (73.6%) had vomiting. The site of impaction was the post-cricoid region in 22 patients (66%), the lower oesophagus in 5 (15%), the mid-oesophagus in 4 (13%), the posterior pharyngeal wall in 1 (3%) and the pyriform fossa in 1 patient (3%). Coins were the most common foreign body (61.8%). Socioeconomic analysis showed that 18 patients (52.9%) were in the low socioeconomic class, 12 (35.3%) in the middle class and 4 (11.8%) in the upper class.ConclusionThe presence of a foreign body in the oesophagus is a serious condition, and early removal is recommended. Foreign body lodgement is commoner among poor families

Application of Response Surface Method in Reverse Osmosis Membrane to Optimize BOD, COD and Colour Removal from Palm Oil Mill Effluent

Palm oil mill effluent (POME) is typically non-biodegradable and has high concentration of organic matter that represented as COD, BOD and Colour values. The correlation of concentration and pH of POME, and Trans membrane pressure (TMP) of Reverse Osmosis (RO) membrane was optimized by response surface method using a second order polynomial model with central composite design (CCD) which is a part model of response surface method (RSM) in Design-Expert® software. The main limits that influenced the parameters removal i.e. concentration of POME, pH of solution and transmembrane pressure were empirically determined at laboratory level and successfully optimized using RSM. The best conditions were determined from 3D response surface and 2D contour graphs i.e. 10.05% of POME concentration at pH 3.0 and TMP 0.50 kPa to yield the last values of COD, BOD and Colour i.e. 24.1372 mg/L,  24.33 mg/L and 11.76 PtCo, respectively.  The results show that the response surface method effective to reduce the number of experiment

EFFECT OF YARN COUNT & STITCH LENGTH ON SHRINKAGE, GSM AND SPIRALITY OF SINGLE JERSY COTTON KNIT FABRIC

Single jersey cotton weft knitted fabrics tend to undergo a certain dimensional changes due to different yarn parameters and knitting parameters. The investigation was carried out to compare the effect of different yarn counts & stitch lengths on the spirality, GSM and shrinkage of knitted fabric. In this study the experimental results show that when yarn count is fixed, the increment of stitch length results decrement of spirality, increment of shrinkage and decrement of GSM. On the contrary, when stitch length is fixed, the increment of yarn count results increment of spirality, decrement of shrinkage and decrement of GSM. Some exceptions were also experienced

Caesarean delivery and its association with educational attainment, wealth index, and place of residence in Sub-Saharan Africa : a meta-analysis

Caesarean delivery (C-section) has been increasing worldwide; however, many women from developing countries in Sub-Saharan Africa are deprived of these lifesaving services. This study aimed to explore the impact of certain socioeconomic factors, including respondent’s education, husband’s education, place of residence, and wealth index, on C-section delivery for women in Sub-Saharan Africa. We used pooled data from 36 demographic and health surveys (DHS) in Sub-Saharan Africa. Married women aged 15–49 years who have at least one child in the last five years were considered in this survey. After inclusion and excluding criteria, 234,660 participants were eligible for final analysis. Binary logistic regression was executed to determine the effects of selected socioeconomic factors. The countries were assembled into four sub-regions (Southern Africa, West Africa, East Africa, and Central Africa), and a meta-analysis was conducted. We performed random-effects model estimation for meta-analysis to assess the overall effects and consistency between covariates and utilization of C-section delivery as substantial heterogeneity was identified (I2 > 50%). Furthermore, the meta-regression was carried out to explain the additional amount of heterogeneity by country levels. We performed a sensitivity analysis to examine the effects of outliers in this study. Findings suggest that less than 15% of women in many Sub-Saharan African countries had C-section delivery. Maternal education (OR 4.12; CI 3.75, 4.51), wealth index (OR 2.05; CI 1.94, 2.17), paternal education (OR 1.71; CI 1.57, 1.86), and place of residence (OR 1.51; CI 1.44, 1.58) were significantly associated with the utilization of C-section delivery. These results were also consistent in sub-regional meta-analyses. The meta-regression suggests that the total percentage of births attended by skilled health staff (TPBASHS) has a significant inverse association with C-section utilization regarding educational attainment (respondent & husband), place of residence, and wealth index. The data structure was restricted to define the distinction between elective and emergency c-sections. It is essential to provide an appropriate lifesaving mechanism, such as C-section delivery opportunities, through proper facilities for rural, uneducated, impoverished Sub-Saharan African women to minimize both maternal and infant mortality
