This paper describes the quality determination of heights above mean sea level using RTK GNSS-levelling and new height reference surface SLO_VRP2016/Koper on the city area of Ljubljana. At 57 chosen benchmarks, quasigeoid heights were determined using ellipsoidal heights, determined with RTK GNNS-levelling technique and heights above mean sea level in the new height system SVS2010. The measured quasigeoid heights were compared with values interpolated from the new height reference surface SLO_VRP2016/Koper.

AbstractTwenty-one specimens of pike-perch (Sander lucioperca) were caught in the Danube-Tisa-Danube Canal in the city area of Novi Sad for parasitological examination. The presence of nematodes in the muscles was revealed in three fish. The parasites were identified to belong to the species Eustrongylides excisus, for which the pike-perch is a paratenic host. This finding represents the first determination of the larvae in the pike-perch in Serbia. The pike-perch is infected by ingestion of benthos- or plankton-eating fishes, the second intermediate hosts harbouring the fourth-stage nematode larvae. E. excisus is pathogenic to humans, who may be infected by consuming raw or undercooked fish.

Height System Unification

Abstract. This paper describes how we are contributing to worldwide height system unification (WHSU) by using ocean models together with sea level (tide gauge and altimeter) information, geodetic (GPS and levelling) data, and new geoid models based on information from the GRACE and GOCE gravity missions, to understand how mean sea level (MSL) varies from place to place along the coast. For the last two centuries, MSL has been used to define datums for national levelling systems. However, there are many problems with this. One consequence of WHSU will be the substitution of conventional datums as a reference for heights with the use of geoid, as the only true "level" or datum. This work is within a number of GOCE-related activities funded by the European Space Agency. The study is focused on the coastlines of North America and Europe where the various datasets are most copious.

<p class="IABSSS">Prayer time is locality in accordance with geographic data. For one geographical data will result one of prayer time. But there are different things with this general rule, namely the phenomenon of maghrib twice during Ramadan 1437 H. / 2016 M. in Bandung. There are two prayer schedule format that developed at that time, which is schedule issued by the Ministry of Religious West Java Regional Office (Kemenag) and schedule sourced by online of the Central of Ministry of Religious Affairs. Bandung has elevated above 600 meters mean sea level, but not located on the beach. Such circumstances make different ijtihad scholars of elevation data in the calculation of the prayer times. According to scholars of the city, Bandung has a elevation above 600 meters mean sea level, in the calculation of the maghrib prayer time must take into calculation the height of the place. This is to get results that match the real conditions. Kemenag and BHRD West Java  using real data in the calculation of prayer times. This schedule is much used as a reference by mosques such as the Great Mosque of al-Ukhuwah Bandung, Mosque PUSDAI, Trans Studio Mosque Bandung, and Masjid Istiqomah Bandung.</p><p class="IABSSS" align="center">[]</p><p>Awal waktu salat bersifat lokalitas sesuai dengan data geografis. Untuk satu data geografis akan menghasilkan satu waktu salat. Namun ada hal yang berbeda dengan kaidah umum ini, yaitu terjadi fenomena adzan maghrib dua kali pada saat Ramadhan 1437 H. / 2016 M. di Kota Bandung. Ada dua format jadwal salat yang berkembang saat itu, yaitu jadwal yang dikeluarkan oleh Kemenag Kanwil Jawa Barat dan jadwal yang bersumber dari sistem online Kementrian Agama Pusat. Diantara jadwal tersebut, ada yang menggunakan data ketinggian tempat dan ada pula yang mengabaikannya. Bandung memiliki ketinggian tempat di atas 600 meter dpl, namun tidak terletak di sisi pantai. Keadaan seperti ini menjadikan ulama ilmu falak berbeda ijtihad dalam penggunaan data ketinggian tempat dalam perhitungan awal waktu salat magrib. Menurut ulama falak, kota Bandung yang memiliki ketinggian tempat di atas 600 meter dpl, dalam perhitungan awal waktu salat Magrib harus memperhitungkan ketinggian tempat. Hal ini untuk mendapatkan hasil yang sesuai dengan kondisi real di lapangan. Kemenag dan BHRD Jawa Barat menggunakan data real dalam perhitungan awal waktu salat. Jadwal ini banyak dijadikan acuan oleh masjid-masjid yang besar seperti Masjid Agung al-Ukhuwah Bandung, Masjid PUSDAI, Masjid Agung Trans Studio Bandung, dan Masjid Istiqomah Bandung.</p>
