Asian seabass, Lates calcarifer is a highly valuable and potential candidate species for mariculture. The objectives of the present study were to conduct an onboard fertilization trail to produce viable offspring and see the effects of stocking density of eggs on the fertilization, hatching and survival rate of Asian seabass juveniles. Eggs and sperm were collected during the full moon in May 2019 from the Moheshkhali channel estuary, the Northeast Bay of Bengal, by hand stripping method. Pooled sperm from two males and eggs from a female were used for insemination. Three egg stocking densities (T1- 37 40,000 eggs/batch; T2- 60,000 eggs/batch and T3- 80,000 eggs/batch) was used for this study. The one-way ANOVA (p

The present study discusses a chant theory treatise preserved in the Carthusian compilation manuscript (CZ-Pu I F 17) and based on the Franciscan Hermann Mott’s Musices Choralis Medulla (1670). It sheds new light on the background of the Carthusian arrangement and its connection to the Franciscan original by comparing both versions and trying to discover why the Franciscan treatise was chosen as an exemplar, who the author of the Carthusian treatise was, when and where the Carthusian version was written and used, and finally, through a study of its context and the information given in its manuscript source, how it could be transmitted and what it meant for the Carthusian order.

Sintesis coralline hydroxyapatite (CHAp) dari koral laut yang umumnya menggunakan metode basah yaitu hidrotermal yang memerlukan suhu dan tekanan tinggi. Tujuan dari penelitian ini adalah mengkonversi koral laut Goniopora sp. menjadi CHAp dengan metode sonikasi pada suhu rendah. Goniopora sp. dikalsinasi pada suhu 900 °C selama 3 jam, kemudian direaksikan dengan diammonium hidrogen fosfat [(NH4)2HPO4] dan mono kalium fosfat (KH2PO4) dengan waktu sonikasi 6 jam sampai 24 jam pada suhu 60 °C. Hasil penelitian menunjukkan bahwa telah terjadi perubahan fase dari koral menjadi CHAp yang dapat dilihat dari identifikasi pola difraksi sinar-X khas dari hidroksiapatit dengan derajat kristalinitas sebesar 66% untuk CHAp dengan waktu sonikasi 24 jam. Spektrum Fourier Transform Infra Red Spectroscopy (FTIR) menunjukkan puncak serapan khas dari hidroksiapatit yaitu gugus OH pada 3637 cm-1 sampai dengan 3404 cm-1 fosfat (PO43-) pada 569 cm-1, 603 cm-1, 960 cm-1, dan 1045 cm-1 serta karbonat (CO32-) pada 1456 cm-1 dan 873 cm-1. Carbonated hydroxyapatite yang terbentuk adalah tipe-B. Rasio Ca/P yang dihasilkan untuk CHAp dengan waktu sonikasi 24 jam adalah 1,7.

Med v Ljubljani hranjenimi fragmenti koralnih rokopisov so ostanki dvodelnega antifonala in psalterja, ki ju je izdelala ista roka. Rokopisi, ki so jim ti fragmenti pripadali, so sledili oglejskemu obredu; nastali so v drugi pol. 15. stol. (ali celo na začetku 16. stol.), se pravi v času, ko je kapitelj novoustanovljene ljubljanske škofije (1461) začel opravljati koralno bogoslužje. Uničeni so bili v drugi pol. 17. stol., ko je bil v ljubljanski škofiji stari oglejski obred zamenjan z rimskim. Z ozirom na to je zelo verjetno, da predstavljajo prvi antifonal in psalter ljubljanske škofije.

The work reports on a naturally prepared solitary coral finding in the glacifluvial sediments of the sand pit in Bernartice nad Odrou. The occurrence of Nordic granitoids and silicites is known at the locality. This coral represents the first finding of macrofossil in quaternary deposits in Bernartice nad Odrou sand pit.

Koprska stolnica hrani sedem v kvadratni notaciji pisanih glasbenih kodeksov, ki izvirajo iz 14. in 15. stol. in vsebujejo glasbo za celotno liturgično leto (z izjemo oficijske liturgije od velike noči do binkošti). Liturgično vsebujejo obred rimske kurije oz. frančiškanskega reda. Kot kasnejši dodatek je v enem od njih celotni oficij sv. Nazarija, prvega koprskega škofa.

Objectives: To ascertain the acceptability of a randomised controlled trial comparing arthroscopic lavage with a placebo-surgical procedure for the management of osteoarthritis of the knee; and to assess the practical feasibility of mounting such a multicentre placebo-controlled trial. Design: Mixed methods study including: focus groups with surgeons and anaesthetists; focus groups and interviews with potential participants; interviews with chairpersons of UK Multicentre Research Ethics Committees (MRECs); surveys of surgeons and anaesthetists; and a two-centre, three-arm pilot. Setting: UK secondary care. Participants: Members of the British Association of Surgeons of the Knee and members of the British Society of Orthopaedic Anaesthetists took part in the focus groups and surveys. Surgeons and anaesthetists from two regional centres in the UK also contributed to focus groups, as did patients from consultant lists in two UK regional centres, and members of Arthritis Care. Chairpersons of six UK MRECs were interviewed. Participants were eligible for the pilot if they were adults (18 years or older) with radiological evidence of osteoarthritis of the knee who might be considered for arthroscopic lavage, and were fit for general anaesthetic (defined by the American Society of Anaesthesiologists grades 1 and 2), and able to give informed consent. Interventions: Participants in the pilot study were randomised to arthrosocopic lavage (with or without debridement at the clinical discretion of the surgeon); placebo surgery; or non-operative management with specialist reassessment. Main outcome measures: The acceptability and feasibility of mounting a placebo-controlled trial for the evaluation of knee arthroscopic lavage. Results: There was broad acceptance across all stakeholder groups of the need to find out more about the effectiveness of arthroscopic lavage. Despite this there was variation in opinion within all the groups about how researchers should approach this and whether or not it would be acceptable to investigate using placebo surgery. Within the health professional groups, there tended to be a split between those who were strongly opposed to the inclusion of a placebo surgery arm and those who were more in favour. For prospective trial participants who had osteoarthritis of the knee, the acceptability of the trial was discussed from a more individual perspective – reflecting on their personal reasons for or against participating. The majority of this group said they would consider taking part. The pilot study showed that, in principle, a placebo-controlled trial could be conducted. It showed that patients were willing to participate in a trial which would involve a placebo-surgical arm and that it was possible to undertake placebo surgery successfully and to blind patients to their allocation – although once patients knew their allocation, some patients allocated to surgery became more concerned about the possibility of undergoing placebo surgery, and withdrew. The experience of the pilot, however, showed that, despite full MREC approval, the study required major discussion and negotiation before local clinical approvals could be obtained. The fact that ethics approval had been granted did not mean that clinicians would automatically accept that the process was ethical. Conclusions: The study showed that, in principle, a placebo-controlled trial of arthroscopic lavage could be conducted in the UK, albeit with difficulty. Against the background of falling use of arthroscopic lavage the decision was, therefore, taken not to proceed to full-scale trial for this procedure. The study showed that for some health professionals the use of placebo surgery can never be justified. It highlighted the importance of the surgeon–anaesthetist relationship in this context and how acceptance of the trial design by both parties is essential to successful participation. It also highlighted the importance of informed consent for trial participants and the strength and influence of individuals’ ethical perspectives in addition to collective ethics provided by MRECs. Trial registration: Current Controlled Trials ISRCTN02328576.

The first choral band of Turkish folk music that is called "Country's Voice Choir" for many years served as a high school in our country and contributed to institutionalizing of folk music. However, it has not been examined alone and has not been the sole subject of any research so far. Only the historical aspects of the "Country's Voice Choir" are emphasized in various sources but there has not been a study on the function, activities, educational system, performances, cultural services and the criticized aspects of the Choir as well as its effects on the present day. This situation created a need for an independent scientific research of the "Country's Voice Choir". The beginning of the cultural journey of "Country's Voice Choir" as a radio program and continuation of its activities under the structure of the radio made it necessary to consider the institutional history of the Choir and the process of radio broadcasting in our country together. The launch of the radio in Turkey, which is one of the mass communication medium, and the inclusion of folk music programmes in its broadcast have not only accelerated the way folk songs of one region are communicated to the another but also broadened the extent of this communication nationwide. Beginning with the individual samples of the folk singers, or âşıklar and local artists, this process gained acceleration by transforming into an institutional, systematic and scientific framework with the foundation of "Country's Voice Choir". In our country, throughout different periods, the presentation of the folk songs obtained through compilation studies to the listener via radio has contributed to the sustainability of a tradition called "Country's Voice Choir" by means of a common language in our country. In this respect, in this article the institutional history of "Country's Voice Choir" which still maintains its activities will be addressed and a multi-faceted analysis of the Choir will be carried out.
