Effects of different levels of oxalic acid administration on feed intake and nutrient digestibility in goats

An experiment was carried out to investigate the effects of oxalic acid administration on feed intake and nutrient digestibility in goats. Four female cross bred (Boer × local) goats (average body weight of 46.3 kg) were randomly assigned to four experimental diets including oxalic acid administration at levels of 0, 2.25, 4.50 and 6.75 g/animal/d in a 4×4 Latin Square design. Oxalic acid diluted with water was administered orally via syringe to experimental goats once daily for four experimental periods. Each experimental period was lasted 21 d in length, comprising 14 d of adaptation to the experimental diet followed by 7 d of data collection. All the animals were individually fed with Napier grass ad libitum supplemented with 300 g (fresh basis) pelleted compound feed per goat per day throughout the study. Feed composition, feed intake, nutrient intake and nutrient digestibility were determined. Intakes of dry matter (DM), organic matter (OM), crude protein (CP), neutral detergent fibre (NDF) and metabolisable energy tended to linearly decrease with the increasing rate of oxalic acid administration, with the value in the 6.75 g oxalic acid/animal/d treatment being significantly (p<0.05) lower than the control (0 g oxalic acid/animal/d) treatment. The oxalic acid administration had no effect on apparent digestibilities of DM, OM, CP and NDF. The experiment demonstrated that oxalic acid administration may influence in the DM and nutrient intakes, but not influence on DM and nutrient digestibilities in goats

Minimize Web Applications vulnerabilities through the early Detection of CRLF Injection

Carriage return (CR) and line feed (LF), also known as CRLF injection is a type of vulnerability that allows a hacker to enter special characters into a web application, altering its operation or confusing the administrator. Log poisoning and HTTP response splitting are two prominent harmful uses of this technique. Additionally, CRLF injection can be used by an attacker to exploit other vulnerabilities, such as cross-site scripting (XSS). According to Open Web Application Security Project (OWASP), CRLF vulnerabilities are among the top 10 vulnerabilities and are a type of injection attack. Automated testing can help to quickly identify CRLF vulnerabilities, and is particularly useful for companies to test their applications before releasing them. However, CRLF vulnerabilities foster a better approach to mitigate CRLF vulnerabilities in the early stage and help secure applications against high-risk known vulnerabilities. There has been less research on CRLF vulnerabilities and how to detect them with automated testing. There is room for further research to be done on this subject matter in order to develop creative solutions to problems. It will also help to reduce false positive alerts by checking the header response of each request. Security automation is an important issue for companies trying to protect themselves against security threats. Automated alerts from security systems can provide a quicker and more accurate understanding of potential vulnerabilities and can help to reduce false positive alerts. Despite the extensive research on various types of vulnerabilities in web applications, CRLF vulnerabilities have only recently been included in the research. Utilizing automated testing as a recurring task can assist companies in receiving consistent updates about their systems and enhance their security.Comment: under peer revie

EFFECT OF PLANT GROWTH REGULATORS ON GROWTH, YIELD AND QUALITY OF TOMATO UNDER DROUGHT STRESS

A Thesis Submitted to the Faculty of Agriculture, Sher-e-Bangla Agricultural University, Dhaka, In Partial fulfillment of the requirements for the degree of MASTER OF SCIENCE IN HORTICULTUREThe experiment was conducted at Sher-e-Bangla Agricultural University, Dhaka during October 2019 to February 2020 to find out the effects of plant growth regulators on tomato growth, yield and quality when subjected to drought stress. Two varieties of tomato namely BARI Tomato 2 and BARI Tomato14 were used in this experiment. The treatments i.e. T = Control (No water stress), T 1 =Drought stress, T 2 0 =Drought + 100 ppm Indole Acetic Acid (IAA), T =Drought + 100 ppm Abscisic Acid (ABA), T = Drought + 100 ppm Salicylic Acid (SA) were used in this experiment. Twenty five days old, healthy and uniform seedlings were transplanted in plastic pot. Ten days after transplanting drought was imposed for three weeks. Ten days after transplanting treatments were also applied by hand sprayer. Three weeks after drought stress the plants were rewatered again. The results indicated that drought stress significantly reduced morphological, yield and quality parameters of tomato. The plant growth regulators effectively reduced the effects of drought stress. Among the plant growth regulators, IAA is the most suitable for mitigating drought stress and maintaining tomato growth, yield and fruit quality

EFFECT OF ORGANIC MANURES AND NITROGEN ON THE GROWTH AND YIELD OF BRINJAL (Solan maongma L)

A Thesis Submitted to the Department of Horticulture Sher-e-Bangla Agricultural University, Dhaka in partial fulfillment of the requirements for the degree of MASTER OF SCIENCE (MS) IN HORTICULTUREBrinjal (Solanum melongena L.) is one of the most important vegetable crops in terms of both acreage and production in Bangladesh and widely cultivated throughout the country. The experiment was carried out during the period from March to October 2006 at Sher-c-Bangla Agricultural University, Dhaka Lo find out the effect of organic manures and different levels of nitrogen on the growth and yield of brinjal. There were three nitrogen levels, No (control): No nitrogen, N1: 100 kg nitrogen/ha and N2: 150 kg nitrogen/ha and three different treatments of manures; Mo (Control): No manure, M I 0 ton cowdung /ha and M2: 3 ton poultry litter/ha. The experiment was laid out in a randomized complete block design (RCBD) with three replications. Increasing the dose or nitrogen increased the plant height, number of leaves, days Lo first flowering, number of flower, number of fruit, length and diameter or fruit, weight or x 1: individual fruit, total yield of fruit per plant and number of fruit per plant. Plan! height (45.18 cm), number of leaves (93.0), length ( 13.70) and diameter of fruit (4.0), number of fruit per plant ( 17.8), weight of individual fruit (88.92 g) and total weight of fruit per plant (1602. I g) was the highest in M1• M1 gave the highest yield than M2 and Mo (control). The combined effect or M1 and N~ produced the highest yield (30.20 ton/ha) of brinjal. Maximizing the yield or brinjal besides organic manures inorganic fertilizer (nitrogen) needed to be use

Fully Fuzzy Linear System in Circuit Analysis with the Study of Weak Solution

In this paper, a simpler method to solve a fully fuzzy linear system (FFLS) with unrestricted coefficient matrix is discussed. FFLS is applied in circuit analysis instead of crisp linear system to reflect the real life situation much better. Arithmetic operations of triangular fuzzy number (TFN) are justified by forming FFLS in an electrical circuit with fuzzy sources and fuzzy resistors and then the system was solved by the simpler method. Finally, the case of weak solution is overcome by proposing a new definition of TFN. Keywords: Fuzzy number, Triangular fuzzy number, Fully fuzzy linear system, Circuit analysis, Weak solutio

Perspective and Challenge of Tidal Power in Bangladesh

Tidal power can play a vital role in integrating as new source of renewable energy to the off-grid power connection in isolated areas, namely Sandwip, in Bangladesh. It can reduce the present energy crisis and improve the social, environmental and economical perspective of Bangladesh. Tidal energy is becoming popular around the world due to its own facilities. The development of any country largely depends on energy sector improvement. Lack of energy sector is because hampering of progress of any country development and energy sector will be stable by only depend on sustainable energy sources. Renewable energy is the only sustainable solution of secure energy which is environmental friendly. Bangladesh has a huge potential of tidal power at different locations but effective measure on this issue have not been considered sincerely. This paper summarizes the current energy scenario and Bangladesh can produce power approximately 53.19MW across the country to reduce the growing energy demand utilizing tidal energy as well as it is shown that Sandwip has high potential of producing tidal power which is approximately 16.49MW by investing only US $10.37 millions. Besides this, cost management for tidal power plant also has been discussed
