This paper presents an improvement in the design of engine crane, introducing a rotating mechanism comprising a gearing system, electric motor, solid shaft with flange, sleeve bearing, and a support bearing. The precision cut gears used are made of steel with endurance strength of 55 MN/m2 (according to the American Gear Manufacturers Association (AGMA). In the design, the limiting endurance load of 17.06 KN and the limiting wear load of 22.96 KN are greater than dynamic load of 10.83 KN which implies the design is satisfactory from the standpoint of wear, dynamic and endurance loads. Since the use of cranes is indispensable in the industry, the design will aid productivity, safety of workers, ergonomics, efficiency, effectiveness and versatility of the cranes, for which they are designed and manufactured.

Key words: design, dynamic load, engine crane, limiting endurance, rotating mechanism.

The method used by the technical teams during repairs on gearboxes of automobile always poses danger, the faulty gearbox, at a stage, has to be removed and some components restored or completely replaced. This technique has always been causing fatigue and much risk of worker injury; endangering the lives of mechanics. This paper presents the design of an efficient, reliable, ergonomic, safe and cost-effective device to hold the automobile gearbox in position during its maintenance. The main components of the design include gearbox, support plate, power screw, link and spur gears. The mechanism in the design causes the reciprocating movement of the support plate when the power screw connecting the two brackets performs rotational motion. The base in the form of a board with wheels makes easy the drawing and pushing of the device with the gearbox on it. Mild steel was used as the material. The efficiency of the device is good enough to be used for the purpose for which it is designed. The device will save time, minimize and eliminate wasted efforts, risks and dangers involved in holding gearboxes of automobile during maintenance workshops.

The attempts made to treat invasive liver cancer have failed so far at an alarming rate. One effective strategy used recently is low frequency pulsed magnetic field therapy. Coil A of intensity 13-42 gauss; 2-3 Hz and Coil B of 0.6 Tesla <1 Hz were evaluated on diethylnitrosamine-induced rat liver cancer. Furthermore, an exposure system was designed to provide a safe, selective and a noninvasive therapeutic device designed according to the international safety standards of therapeutic devices. The histopathology and ultra-structure of liver tissues suggest a selective anticancer activity of these magnetic fields through incorporating three main strategies. These strategies consist of apoptosis, necrosis and the inflammatory infiltration of the malignant carcinoma. These results simulate the gene therapy and immunogenic therapy of liver cancer. Finally, it can be concluded that the exposure system coil A of 3 Hz and coil B 0.9 Hz will contribute to magnetic therapy.

The normal interaction between steel and concrete is lost because the tendons are unbonded with the concrete cross section. Therefore the assumption of plane sections is no longer valid. External pre-stressing has been proven cost effective and technically attractive worldwide, as it leads to substantial cost savings and a large decrease in construction time. If the purpose of the project is to improve the load carrying capacity of existing bridges, then tendons are usually, placed outside the bridge girders, tensioned and anchored at their ends. The external tendons can be made of steel, but also with fibre reinforced polymeric (FRP) materials and they provide one of the most efficient solutions to increase the rating capacity of existing bridges when the infrastructures are in need of renewal and made of all structural materials, such as concrete, steel and timber. There are some different techniques to strengthen existing structures such as plate bonding, external pre-stressing, over-slabbing or increasing the ratio of bonded reinforcement. Recent works on structural repair procedures have shown that reinforced concrete beams can retain as much as 85% of their flexural capacity. While there are similarities between external pre-stressing and external reinforcement, the structural principles in which the two methods work are different. In present paper work, we are made only study different researchers works on different parameters which are affected on externally prestressing. We were collected the information on external prestressing from different research papers and made discussion on parameters which are affected on it.

In this paper, we have developed a block cipher, which includes a key matrix and a key bunch matrix. In this, we have used the basic concepts of Hill cipher and the concept of the multiplicative inverse. This analysis is supplemented with a function, called Mix(), for creating confusion. The cryptanalysis carried out in this investigation firmly indicates that this cipher is unbreakable by all possible attacks, available in the literature.

A phenomenal growth in the number of credit card transactions, especially for on-line purchases, has also led to a substantial rise in fraudulent activities. Credit card fraudulent transactions are very easy to conduct, while very difficult to recover, compared to the fraud cases in hard-products transactions. In real life, fraudulent transactions could be interspersed with genuine transactions and simple pattern matching techniques are not often sufficient to detect the fraudulent transactions efficiently. Moreover, surrogate representations of identity can be easily forgotten, lost, guessed, stolen, or shared. Further it can be hacked through malicious websites or prone to security breaches. Implementation of efficient fraud detection systems has thus become imperative for all credit card companies in order to minimize their losses.In this paper, we propose a IRPV (Iris Recognition and Palm Vein) recognition technology which will help add even more security to existing biometric devices that may be susceptible to fraud. The techniques used are Palm vein technology, along with iris recognition. It is difficult to crack, because each person's vein pattern is unique. Thus, biometric systems impart higher levels of security when appropriately integrated into applications requiring user authentication. The experimental results show that the detection rate would prove 99.995% compared to traditional methods.

Farm management system leads to intensive use of chemical fertilizers and pesticides overdose, apparently a serious impact on the decline in land productivity and degradation of agro-ecosystems. Management of organic potato farms Local Potential Intensification System aims to improve the potential of local resources and increase the fertility of the land to be utilized in a sustainable manner. The research method; the study took place in Batu, Malang and retrieval of data is done by survey. Respondents are experienced potato farmers and revered as the expert. Analysis of data using Strategic Analysis (SWOT) and Analitycal Hierarchy Process (AHP), [23](Saaty, 1993). The determination of criteria and sub-criteria approach SIPLO do pairwise comparison method in the AHP, the results of the analysis can be defined hierarchy of priority criteria and sub-criteria for testing linkage SIPLO and SWOT analysis on the value of the relationship vision, mission and values that influence the management of potato farms [24] (Akdon, 2009). The result, a policy strategy that must be addressed: (1). Introduction SIPLO profile strategic priority value 12, (2). Socialization, training and make a pilot strategic priority value 12, (3). Establish partnership with educators and the government or the competent strategic priority value 12. Conclusion; the strategy of sustainable land management and land productivity potatoes can be increased and the state of agro-ecosystems can be repaired, it is necessary to: (1). Implementation SIPLO on organic potato farms. (2). In engineering applications SIPLO the time of induction of land must be in wet or flooded. (3). To increase productivity and improvement of the agro land at land management should be given an appropriate organic fertilizer type, maturity and recommended doses of fertilizer. (4). Organic fertilizer should be given to speed up the process of bacterial decomposition of soil organic matter mineralization.
