Skidding of logs uphill is a big task which can not be done manually. Various types of winches are utilized for this purpose. The friction on the ground due to skidding of logs calls for powerful winches but if logs are hauled along the skyline then the power required is much less. The present study in the hauling up by short distance skyline crane was conducted in Logging Division Uttarkashi U.P. in December 1968. The cost of working comes to Rs. 574 per cu m which is quite reasonable for such work. A further reduction in cost figures by 10 to 12% may be possible if the steps suggested in the paper are taken up.- Attitude towards Cheating among Students of Professional and Non-professional Courses

The study was done to compare the attitude towards cheating of the professional and non-professional course students. In this study the sample consisted of 40 professional and 40 non-professional course students, studying in various professional and non-professional colleges in Jammu city. For the measurement of Attitude towards Cheating, Attitude towards cheating scale developed by Sharma was administered on the sample. It consists of 35 statements which are either positive or negative. Responses were to be obtained on five point scale. t-test was used for statistical analysis. The finding of this study showed that the students of professional courses have more positive attitude towards cheating as compared to the students of non-professional course. The value of t=16.45 was found to be statistically significant at .05 level between the two group of subjects.Keywords

Fracture resistance of endodontically treated teeth restored with post. Aims:This study aims to compare the fracture resistance of endodontically treated teeth restored with resin fiber and stainless steel post. Commercially available prefabricated resin fiber post (Dentsply Maillefer Easy Post), prefabricated stainless steel post (Coltene/Whaledent Parapost) were used. Methods & Material: Forty five maxillary central incisors were obturated and divided into 3 groups: Control Group (Group I) without any post (n = 15), Resin Fiber Post Group (Group II) (n = 15) and Stainless Steel Post Group (Group III) (n = 15). In all Groups except control group, post space was prepared; a post was cemented, and a core build-up was provided. All the specimens were subjected to compressive force under a universal testing machine until fracture. Statistical analysis used: The results were analyzed using the variable analysis test (ANOVA). Results: One-way analysis of variance revealed significant difference among test groups. The control group demonstrated highest fracture resistance (925.2183 N), followed by the resin fiber post group (486.7265 N) and stainless steel post group (423.539N). Conclusion: Teeth restored with resin fiber post showed higher fracture resistance values than prefabricated stainless steel post.Keywords

Peptic ulcer is a break in the lining of the stomach, first part of the small intestine, or duodenum. The duodenum is the first part of the small intestine. Contrary to popular belief, ulcers are not caused by spicy food or stress but instead are most commonly due to either an infection or long-term use of certain medications. The main goals for treating a peptic ulcer include eliminating the underlying cause (particularly H. pylori infection or use of NSAIDs), preventing further damage and complications, and reducing the risk of recurrence. Peptic ulcer which is mainly caused by bacterial attack or excess of acid secretion can be cured effectively by these isolated plant compounds. A number of drugs including proton pump inhibitors and H2 receptor antagonists are available for the treatment of peptic ulcer, but clinical evaluation of these drugs has shown incidence of relapses, side effects, and drug interactions. This has been the rationale for the development of new antiulcer drugs and the search for novel molecules has been extended to herbal drugs that offer better protection and decreased relapse. Craving for herbal medicines are still importance due lesser chance of adverse effects and easily available in surrounding place with low cost. In this review attempts have been made to summarize medicinal plants and their constituents used for peptic ulcer by the people of rural area which may be beneficial for the modern science.Keywords

Unmanned aerial vehicles (UAVs), commonly called ‘drones’, have enormous potential for technological advances in many sectors including agriculture. The recent revision in UAV policy by the Directorate General of Civil Aviation (DGCA), India, can impact the pace of research and development in machine vision capabilities in the country. Several other countries that have framed UAV policy previously, are continuously bringing changes to the existing framework to make it more user friendly. India can learn from those changes and bring out a comprehensive update to foster a broader application of these tools in agriculture. This policy review provides suggestions and solutions for increasing licensing centres, limiting UAV speed and weight for safer flights and including aerial pesticide applications in UAV permits to revolutionize the multibillion-dollar agriculture industry. This article has also examines the current UAV regulations in four other countries.Keywords
