A COMPARATIVE STUDY OF DIFFERENT METHODS OF MEAT PRESERVATION
(Chittagong Veterinary & Animal Sciences University, Khulshi- Chittagong-4225, 2013-02) Islam, Md. Manirul
The study was conducted to observe comparative assessment of meat preservation by using different method. The experiment was divided into three treatment groups having two replications. Three samples were collected from locally available markets. Where sample 1 was persevered by freezing method, sample 2 by pickling with vinegar and sample 3 by salting with common salt. The initial pH of the meat samples (S1,S2, S3) were 5.84, 6.33 and 5.90 respectively. The initial moisture percentage of these (3) samples were 77.43, 70.25 and 76.10, respectively. And the total viable count of bacteria was(1.8x106/CFU) in sample1, 2.3x106/CFU) in sample3 which were negligible and in sample2 the microbial load was 14x106CFU/gm. After one month of preservation, the second reading was taken from the same samples. There are some changes observed in pH, moisture, texture, color and TVC. It is revealed that the preserving of meat by salting is significantly better than other two methods. So, it may be concluded that the meat preserving by salting more safety, more reliable and more economic for human consumption.

(Daffodil International University, 2019-04) Islam, Md. Manirul; Nayem, Md. Jannatul; Mondol, Md. Rezwan
At present wireless network trends to be more and more popular among the population with the millions of users. The Man-In-The-Middle (MITM) attack is one of the most well-known attacks in computer security, representing one of the biggest concerns for security professionals. MITM targets the actual data that flows between endpoints, and the confidentiality and integrity of the data itself. MITM has been one kind of attack where a user gets between the sender and the receiver information. In this report we try to explain different types of MITM attacks. Man in the Middle (MITM) attack is one of the primary techniques in computer base hacking. In this types of attack where the attackers can collect many important data, inject false information, user lost their different types of online user ID and password. For this, we try to discover how this types of attack works, describe a method of man-in-the-middle attack based on ARP spoofing and try to create a method of preventing suck attack.
Study on the Profitability of rural goat rearing at Noakhali and Chittagong Districts
(Chattogram Veterinary and Animal Sciences University Khulshi, Chattogram-4225, Bangladesh, 2011-01) Islam, Md. Manirul
The study was conducted to analyze profitability of goat rearing under rural condition by collecting data from various goat rearers at village condition. Data were collected from two upazillas namely kabirhat under Noakhali & Satkania under Chittagong district during the period of October to December 2010. Finally these collected data were put to make questionnaires. In total of 50 farmers were selected for the study by following stratified random sampling technique. The study revealed that about 36.66%, 30%, 13% & 20% were landless, small and marginal, medium & large farmers respectively according to their landholding sizes. Result of this study showed that total cost of rearing was Tk1180.23/goat/year and total return from goat rearing was Tk3983.98/goat/year. The result clearly indicated that goat farming was profitable for the villagers.
