Abstract The development of the Underway Conductivity–Temperature–Depth (UCTD) instrument is motivated by the desire for inexpensive profiles of temperature and salinity from underway vessels, including volunteer observing ships (VOSs) and research vessels. The UCTD operates under the same principle as an expendable probe. By spooling tether line both the probe and a winch aboard ship, the velocity of the line through the water is zero, the line drag is negligible, and the probe can get arbitrarily deep. Recovery is accomplished by reeling the line back in. Recovering the UCTD has some advantages: 1) the cost per profile decreases with increasing use, 2) sensors can be calibrated postdeployment, 3) the UCTD carries a pressure sensor so depth is measured directly, and 4) no hazardous materials are left behind. The design goal for the UCTD was to obtain profiles deeper than 100 m at 20 kt (typical of a VOS). This goal has been surpassed, as it is able to profile to over 150 m at 20 kt and to over 400 m at 10 kt. The first operational use of the UCTD occurred during a May–June 2004 cruise, the purpose of which was to examine the effect of internal waves and spice on long-range acoustic propagation. Over 160 UCTD casts were completed, resulting in a hydrographic section with resolutions of 10 km horizontally and 5 m vertically.

Among the chronicles relating the heroism of the besieged Leningrad, there are pages dedicated to the deeds performed by the staff the world-famous All-Union Research Institute of Plant Industry (VIR, now the N.I. Vavilov All-Russian Institute of Plant Genetic Resources). With the beginning of the war, even before the city was surrounded by the Nazi troops, the government decided to evacuate a number of factories and institutes from Leningrad, including VIR, but the plan failed. Only in winter did the Institute start partial evacuation, although preparations had been going on for a long time. The largest and most important part of the collection was left behind in the besieged city. The remaining employees were forced to work under the hardest conditions of the siege, in unheated premises. In the harsh reality of the winter in 1941–1942, the daily bread rationing was cut down, and hunger raged in the city, killing tens of thousands of city residents, including VIR employees who kept the stored seeds and tubers untouched. The most difficult part was preserving the potato collection. In the spring of 1942, preparations were made for sowing to restore the viability of seeds and tubers in the fields of Leningrad’s suburban area under the fire from the enemy artillery. Only the heroic efforts of VIR’s staff helped to save the collection from destruction and loss of germination. This heroism cost more than 20 experts and scientists their lives. So, the most dangerous period for the Institute was overcome at such price. Immediately after the siege was lifted, a group of experts was sent to Leningrad from Krasnoufimsk to help with selecting seed accessions for urgent reproduction. Working under extreme physical exhaustion in frozen premises, without water or electricity, under continuous shelling, they saved, many at the cost of their own lives, the collection of cultivated plants and their wild relatives, the herbarium, and the scientific library for future generations.

In this paper, a logic selectivity system based on Long Range (LoRa) technology for the protection of medium-voltage (MV) networks is proposed. The development of relays that communicate with each other using LoRa allows for the combination of the cost-effectiveness and ease of installation of wireless networks with long-range coverage and reliability. The realized demonstrator to assess the proposed system is also presented in the paper; based on different types of faults and different locations, the times needed for clearing a fault and restoring the network were estimated from repeated experiments. The obtained results confirm that, with an optimized design of transmitted packets and of protocol characteristics, LoRa communication grants fault management that meets the criteria of logic selectivity, with fault isolation occurring within the maximum allowed time.

ABSTRACTHajj as a great symbol of worship. Hajj is the fifth pillar of Islam which is mandatory for every Muslim who are able to da it in accordance with the legal requirement of pilgrimage. One of the legal conditions of Hajj is the capability, capable to cover the cost of the hajj and the family left behind. Panin Bank Dubai Sharia Bank was established based on the regulation of Limited Company No. 12 dated January 8, 1972 by Moeslim Dalidd, a notary in Malang. PT. Bank Panin Dubai Syariah Tbk has been legalized by the Financial Services Authority ("OJK"), in accordance with a copy of the policy of the Board of Commissioners of OJK No. Kep-29 / D.03 / 2016 on July 26, 2016.Therefore, through this research, the writer wants to understand: (1) how is the practice of applying alternative financial agreement of hajj and umrah after the implementation of regulation made by ministry of religious affair No. 24 year 2016 at Panin Bank Dubai Syariah Surabaya branch? (2) What is the analysis of Islamic law on the practice of multilateral contract alternative application in this Bank? Therefore, this study is aimed to, firstly, understand and describe the application of alternative contracts to hajj and umrah after the regulation of Ministry of Religious Affairs No. 24 of 2016 in Panin Bank Dubai Sharia branch Surabaya, and to describe the analysis of Sharia Economic Law about the practice of applying alternative contract in the bank.The method used in this research is qualitative method. The research data are taken in natural situation in Panin Bank Dubai Syariah Surabaya. The data are taken during operational hours using case study approach. Are done through interview technique with the main participant, Assistant Manager 1, and document, archive, book, sample of registration, as secondary data source. The data are analyzed through 3 (three) data deduction, display data and ended with conclusion and verification.The results of the study indicate that the Panin Bank Dubai Sharia runs in accordance with the government regulation No. 24 year 2016 "BPS BPIH is prohibited from providing direct and indirect Hajj money service" including Hajj and Umrah services using various financing products and funds saving, funds collecting in the form of deposits, savings or other forms, using multi-service financing akad wadi'ah, with the savings of hajj services with initial minimum deposit of Rp500,000,and according to customers’ ability. Keywords: hajj, umrah, wadi'ah.

AbstractThis paper presents an approach for decoding the pressure information exerted over a piece of fabric by means of resistive sensing. The proposed sensor includes a distributed resistive grids constructed by two systems of orthogonally contacted electrical conductive yarns, with no external sensing element to be attached on the fabric. Since the conductive yarns serve as the sensing and wiring elements simultaneously, this design simplifies the fabrication process, reduces the cost and makes the production of large area flexible pressure sensor possible. The location of the pressure applied on the fabric can be identified by detecting the position where the change of the resistances occurs between two embroidered yarns. Meanwhile, the magnitude of the pressure can be acquired by measuring the variations of the resistance. In order to eliminate the “crosstalk” effect between adjoining fibers, the yarns were separately wired on the fabric surface.
