The seventh season of excavation at Can Hasan began on 9th September and stopped on 28th October; a further week was spent working on the finds and on the site. Site supervisors were Bay Altan Atılgan, and Messrs. S. W. Helms, R. Howell, and J. N. Postgate. In the House the work was undertaken by Bayan Behin Aksoy, Bayan Ülge Göker, Miss Carolyn Prater, Mrs. Cressida Ridley and Miss Monika van der Zwann. Bay Bedri Yalman represented the Turkish Government for a short period until called away to military service; his place was taken by Bay Cengiz Karadağ.A new method of sieving was introduced this year at the suggestion of Mr. Sebastian Payne. Instead of small hand sieves, “shakers”, built under Mr. Payne's supervision, were used. Basically this type of “shaker” is three removable trays with mesh of differing size (10 mm., 5 mm., 1 mm.) set on a sprung metal framework. It was also found more practicable with soils containing a lot of grain to “wash out” the grain from the soil remaining in the last tray after the soil had received preliminary hand-searching.

Summary A loss of functional motor axons in the median and ulnar nerves occurred in half of thirty-three patients with rheumatoid arthritis. Weakness of small hand muscles may predispose to the development of ulnar deviation of the fingers in patients with joint disease at the radio-ulnar and metacarpophalangeal joints. There is no evidence that spasm of small hand muscles is a significant cause of ulnar deviation of the fingers in rheumatoid arthritis. Ulnar deviation of the fingers in rheumatoid arthritis is not due to selective impairment of the ulnar nerve or the deep palmar branch of the ulnar nerve even though ulnar deviation of the fingers can occur in association with such lesions and in the absence of joint disease.

After surveying the various types of hot rolling mill units for heavy ingots and their evolution, the author selects for description certain examples of progressive design from his own recent experience. These include an adaptation of modern heavy mill manipulation to an existing blooming mill, incorporating fabricated steel structures in place of steel castings for mill tables, small hand-worked mills for the accurate finish of high-class steels in small bar sizes, a modern high-production four-strand continuous wire rod mill plant, and two examples of development in rolling mill auxiliaries. The question of roll neck bearings is discussed and a special bronze and white-metal combination roll neck bearing is described.

At the end of 2019, coronavirus disease (COVID-19) outbreak is caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV2). Worldwide researchers and physician try to explore the mechanisms of damage induced by virus, they focus on the short-term and long-term immune-mediated consequences induced by the virus infection. Every day discover a new pathological condition induced by virus and new symptoms and disease may occur after recovery from disease. Our case report is 41 years old, Indian lady who presented to our primary health care centre complaining of multiple small hand joints pain, both elbows and knees pain with swelling of them and prolonged morning stiffness, diagnosed seropositive rheumatoid arthritis (RA) (arthritis, positive rheumatoid factor (RF), and X-ray changes) after 1 month recovery from COVID-19 infection. She did not have any joint pain and she had negative RF before COVID-19 infection with no family history of RA.

Smartphone plays a key role in integrating the entire world into a small hand. This feature made these smartphones as another human organ of many people. One of the main feature in every smart phone is GPS which used to travel new places, to locate and find optimized way to reach their destination. As we aware GPS is an outdoor application, GPS location is not accurate in indoor and small scale areas. This leads to an advanced research to improve the accuracy in GPS positing for the benefit of indoor applications. This research proposes a new iBeacons based Improved Indoor Positioning System for indoor positing application using Bluetooth low energy (BLE) beacons. This model helps the mobile application to find the exact location at micro-level scale. The objective of this research work is to design a potable indoor positing system (IPS) for indoor applications with at least 100m accuracy with in the inbuilt energy resource limitations. The proposed model has been built and verified in all the aspects. The location accuracy and energy efficiency of the proposed model is compared and found better than the existing models

About ten years ago this author wrote the software for a suite of navigation programmes which was resident in a small hand-held computer. In the course of this work it became apparent that the standard text books of navigation were perpetuating a flawed method of calculating rhumb lines on the Earth considered as an oblate spheroid. On further investigation it became apparent that these incorrect methods were being used in programming a number of calculator/computers and satellite navigation receivers. Although the discrepancies were not large, it was disquieting to compare the results of the same rhumb line calculations from a number of such devices and find variations of some miles when the output was given, and therefore purported to be accurate, to a tenth of a mile in distance and/or a tenth of a minute of arc in position. The problem has been highlighted in the past and the references at the end of this show that a number of methods have been proposed for the amelioration of this problem. This paper summarizes formulae that the author recommends should be used for accurate solutions. Most of these may be found in standard geodetic text books, such as, but also provided are new formulae and schemes of solution which are suitable for use with computers or tables. The latter also take into account situations when a near-indeterminate solution may arise. Some examples are provided in an appendix which demonstrate the methods. The data for these problems do not refer to actual terrestrial situations but have been selected for illustrative purposes only. Practising ships' navigators will find the methods described in detail in this paper to be directly applicable to their work and also they should find ready acceptance because they are similar to current practice. In none of the references cited at the end of this paper has the practical task of calculating, using either a computer or tabular techniques, been addressed.

Due to the rapid growth of small and smart hand-held devices, mobile ad hoc networks (MANets) are becoming very common nowadays. MANets may consist of a number of small hand-held devices having limited resources in terms of memory, battery and processing power. In order to provide services to the users, these devices are capable of communicating with each other through some radio technology, such as WiFi, Bluetooth or Infrared. Since radio channels are inherently vulnerable to various security threats, it requires that devices in MANets must establish a secure association amongst themselves before exchanging any sensitive information or data. The process of establishing a secure channel between two devices is referred to as device pairing or device association. Device pairing do not rely on traditional mechanisms for security due to the impulsive and ad hoc interactions among the devices. Due to this, researchers have proposed many schemes/protocols to deal with this issue; however, the issue of group pairing (i.e. secure association of more than two devices) is less addressed issue in the literature yet. There could be many scenarios (such as confidential office meetings, paring of group of home appliances in smart-homes, etc) of MANets, where secure group communications is desired. Consequently, this research focuses on this issue and proposes a QR (quick response) code based scheme to establish a secure channel between a numbers of devices. The proposed system is implemented and tested on modern hand-held devices and a usability study of the implemented system is also carried out.
