Mastitis is one of the most economically important diseases of dairy animals in Pakistan. The cure rate of mastitis with the use of antibiotics/antibacterials leaves a lot to be desired. In addition, the use of these agents leads to undesireable residues in milk and poses a host of problems to milk processing industry. Therefore, measures other than the use of antibiotics/antibacterials are being investigated to improve the mastitis cure rate. Keeping these considerations in perspective, the current study was planned with the objective to evaluate the therapeutic efficacy and cost-effectiveness of autogenous herd and animal-specific mastitis vaccines alone and in combination with antibiotic based rational therapy after investigating the magnitude of clinical and subclinical mastitis in Tehsil Faisalabad. The current study was compartmentalized into 3 parts. In part I of the study, cattle and buffaloes of 19 villages from 59 Union Councils of Tehsil Faisalabad were screened for subclinical mastitis using surf field mastitis test (SFMT) and 10% of the randomly selected clinically and subclinically mastitic quarters were subjected to microbiological examination of milk. Part II of the study envisaged evaluation of herd-specific mastitis vaccines in 3 dairy herds managing at least 50 animals. The mastitic animals of each farm were randomly divided into 3 equal groups.Group 1 received herd-specific mastitis vaccine @ 5ml/animal I/M twice at an interval of two weeks (Protocol I). Group 2 was treated with standard mastitis therapy i.e. Tylosin @ 10mg/kg for three days I/M + amoxicillin & clavulanic acid @ 600 mg I/mm infusion daily for 5 days (Protocol II) whereas Group 3 received combination of herd-specific autogenous vaccine and standard mastitis therapy (Protocol III). Part III of the study aimed at evaluation of animal-specific autogenous vaccines on 60 (clinical n=30; subclinical n=30) cows and buffaloes belonging to small holder farmers and commercial or institutional farms. Evaluation parameters of part II and III of the study included: clinical severity score, SFMT score, clinical and bacteriological cure rate, somatic cell count (SCC), milk quantity and any untoward effect. Cost-benefit analysis of protocol I, II and III was conducted. The data thus generated were analysed using analysis of variance (ANOVA) and Chisquare test, where relevant. Regarding prevalance of mastitis A total of 24467 buffaloes and 13061 cows were screened during this study.A total of 4231 buffaloes and 3256 cows were found to be suffering from mastitis indicating 17.29 and 24.93% prevalence in the respective species. The overall or composite (buffaloes plus cows) prevalence was 19.95%.Whereas regarding occurrence of mastitic pathogens, Staphylococcus aureus was most predominant micoorganism in the locale. A better SFMT based cure rate, clinical cure rate, bacteriological cure rate and significantly reduced somatic cell counts and plate count values were observed in animals which were provided with herd-base or animal base autogenous mastitis vaccine alone or in combination with antibiotic therapy in subcinically or clinically mastitic animals. When cost benefit analysis of the protocol-I was carried out it resulted in an average net profit ofRs.359/animal/day on herd basis, while Rs. 331.75 and 362.65/animal/day for subclinical and clinical mastitis when prepared on animal-specific basis.

بدالدجیٰؐ کی بات ہے اور ہم ہیں دوستو

بدر الدجیؐ کی بات ہے اور ہم ہیں دوستو!
ذکرِ نبیؐ کی رات ہے اور ہم ہیں دوستو!

ہر حرفِ احتیاط ہے اور ہم ہیں دوستو!
نوکِ قلم پہ نعت ہے اور ہم ہیں دوستو!

اُس بارگاہِ ناز میں مدحت کے پھول ہیں
مداح رب کی ذات ہے اور ہم ہیں دوستو!

اِس بزمِ خاص میں ہے فقط اُنؐ کا تذکرہ
میرے نبیؐ کی بات ہے اور ہم ہیں دوستو!

لمحے ہماری عُمر کے کتنے قلیل ہیں
کتنی طویل بات ہے اور ہم ہیں دوستو!

یہ فخر ہے کہ اُمّتی خیرالورؐیٰ کے ہیں
مقصودِ کائناتؐ ہے اور ہم ہیں دوستو!

ہر حرفِ نعت ہم پہ عطا ہے حضورؐ کی
یہ قلبی واردات ہے اور ہم ہیں دوستو!

ہم کو تو کائنات ہی لگتی ہے بزمِ نعت

LITERACY EDUCATION URGENCY FOR CENTENNIAL GENERATION IN INDUSTRIAL REVOLUTION 4.0

When talking about children’s abilities, they indeed cannot be separated from their educational or training background. Moreover, he has entered the working age that must have productivity in his work, especially at this time, where the era has entered the industrial revolution 4.0. The industrial revolution 4.0 is marked by the development of digitalization in various lines of life. On the one hand, the industrial revolution 4.0 had many positive impacts. However, on the other hand, as the McKinsey Global Institute states that as a result of the 4.0 industrial revolution in the next five years, there will be 52.6 million jobs that will decline and even disappear. This certainly will be a challenge for the centennial generation (children born from 1996-2011) at this time, which they have to survive with the existing conditions and situations. This paper will discuss several factors that describe and address issues such as what is meant by the centennial generation, literacy, and the urgency of literacy education for the centennial generation in the digital age. According to authors, thi is essential to discuss, given the increasingly rapid development and technological progress resulting in the loss of much work.

Optimization of Space Time Coded Multi-User Systems Through a Variety of Algorithms

Multi-user systems such as Multi-Carrier Code Division Multiple Access (MC-CDMA) and Orthogonal Frequency Division Multiple Access (OFDMA) are very frequently use in modern communication networks like 4G, MOTO4A, etc. These systems utilize the available bandwidth effectively. In order to maximize the capacity and encounter the high data rate demand, much emphasis given to coding techniques for effective utilization of resources at the transmitter end. Similarly, a variety of algorithms is evolve to separate and detect the data of users at the receiver end of multi-user system. Optimization of both transmitter and receiver is still a very attractive research area for future communication systems. One of the famous coding techniques is Space Time Block Codes (STBC). STBC are implement in single layer and does not give so attractive results in multi-user systems. Nowadays, two layer coding mechanism is being used in Multiple Input Multiple Output (MIMO) systems. In this approach, coding process is apply in two layers for better data recovery. In multicarrier systems, Fourier transform is common for frequency domain spreading. It consumes more bandwidth due to addition of cyclic prefixes at transmitter end. Another transformation namely, Slantlet transform is receiving good attention due to its benefit of bandwidth cutback as it does not need addition of cyclic prefixes. The received data can be recover with the help of different conventional adaptive algorithms like Least Mean Square (LMS) and Recursive Least Square (RLS). The conventional LMS and RLS have slow convergence rate and high Bit Error Rate (BER) because of static step size iv and forgetting factor. The performance of these algorithms can be improve with adaptive step size in case of LMS and adaptive forgetting factor in case of RLS for multi-user systems like MC-CDMA and OFDMA. Unconventional algorithms like Genetic Algorithms (GA) and Particle Swarm Optimization (PSO) also used to achieve better performance of multi-user systems. In this thesis, the initial work is divide in two parts on MC-CDMA systems. Initially, the two layered-CDMA codes are focus on MC-CDMA systems. The Multi User Detection (MUD) of this system is implement with conventional LMS and proposed Fuzzy logic based LMS. Later, the single layered space-time block codes is adopt on MC-CDMA systems for exploring the MUD different conventional LMS types. The GA is implement on the same system with proposed GA depth study for MUD. The cooperative coevolutionary algorithms are also test for MUD. In order to overcome high bandwidth consumption issue, the Slantlet transform is propose instead of Fourier Transform for Frequency/Time domain transformations. Lastly, the in depth of MUD on OFDMA is also the part of this thesis. The OFDMA systems are study with proposed Fuzzy LMS and Fuzzy RLS algorithms for MUD. The Soft-PSO is also implement for MUD. Lastly, the proposed algorithm namely Piranha Fish Optimization (PFO) is implement for MUD on OFDMA systems. The opposition based learning concept implemented on PFO. All the proposed schemes evaluated in well comparative manner, which shows its key significance in domain of multi-user systems.
