Članek zarisuje recepcijo gregorijanskega korala v Sloveniji v 19. stoletju. Na podlagi virov opisuje stanje v prvi polovici stoletja ter vpliv prvih poskusov na historistični estetiki utemeljenih ...reformnih prizadevanj. Podrobno opazuje razmah cecilijanskega gibanja po letu 1877 in na podlagi virov analizira sredstva, vsebino in uspešnost njegovih reformnih prizadevanj.
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.
•This is the first study of its kind where onboard fertilization was done.•Onboard fertilization could advantage reproduction of threatened marine species without any domestication.•Identification of ...the breeding ground of the selected species is a prerequisite for onboard fertilization.•A lower stocking density of Asian seabass eggs is better for achieving higher fertilization and hatching success.
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 < 0.05) showed significant effects of egg stocking density on fertilization, hatching success, and survival rate of Asian seabass larvae. The maximum fertilization and hatching success of Asian seabass eggs were 83.05 ± 2.22 and 76.51 ± 1.19%, respectively, achieved with 40,000 eggs/batch stocking density. The highest survival rate was observed in treatment 1 (56.25 ± 3.97%) at 30 DPH, which was significantly different from the other treatments (p < 0.05). Our results indicated that eggs of Asian seabass with a lower stocking density (40,000 eggs/batch) could achieve higher success in fertilization, hatching and survival compared to higher stocking densities (60,000 eggs/batch and 80,000 eggs/batch, respectively). Results from this study could be useful for assisted breeding of Asian seabass in captivity.
Rad nastoji dati suvremeni sintezni prikaz muzikoloških i etnomuzikoloških spoznaja o glagoljaškome pjevanju, temeljem znanstvenih istraživanja koja su obilježila posljednjih pedeset godina hrvatske ...glazbene historiografije. Cilj je također ovaj srednjovjekovni fenomen hrvatske crkvene glazbe promatrati u komparativnome kontekstu obreda Rimske crkve i jedinstvenoga hrvatskoga glazbenog idioma onih geografskih područja na kojima je stoljećima postojalo i opstajalo, asimilirajući u svoj glazbeni identitet pojedine distinktivne karakteristike tradicijske glazbe podneblja u kojem se razvija. Autorica predstavlja konkretne primjere konkordanci gregorijanskoga latinskog pjevanja s elementima glagoljaške pjevane tradicije, poglavito u aspektu glagoljaške psalmodije. Pri tome posebnu pažnju posvećuje najstarijim zapisima glagoljaškoga pjevanja hrvatskih prostora te karakteristikama njihove notacije.
