Authors: Asaduzzaman M , Amin MR , Sarkar NR , Huque KS 
Published: December 2019

The aim of the experiment was to investigate the productive and reproductive potential of pregnant Red Chittagong (RC) cows through improved feeding. A total of 30 pregnant RC cows from each of 30 farmers having six months pregnancy and between 2 and 3 parities old were used in the trial. The cows were randomly allocated to three dietary treatment groups, i.e., T0, T1 and T2. The cows of T0 group received farmers’ diet (63% of dry matter intake of cows according to ARC, 1995) without the supplementation and served as control. The cows of T1 group received farmer’s diet (63%) plus 25% supplementation of formulated concentrate diet for deficit of requirement of cows {(63 + 9.25) = 72.25% dry matter intake of cows according to ARC, 1995)} and T2 group received farmers diet (63%) plus formulated concentrate diet to meet 100% requirements of cows according to ARC (1995) {(63% +37%) = 100%}. The total live weight gain before calving of RC cows were observed significantly (P <0.05) higher in T2 and T1 groups than T0 group. The calves birth weight was found significantly (P <0.05) higher in T2group than T1 and T0 groups. The gestation length was increased approximately 3 and 2 days for T2 and T1 groups, respectively, compared to T0 group. Therefore, the farmer’s diet plus supplementation of formulated concentrate diet to meet 100% requirement of cows according to ARC (1995) {(63% +37%) = 100%} was a better improved feeding system of pregnant Red Chittagong cows.

Synthesis and characterization of N, N′-bis (isatin) diamino zirconium (IV) complexes
Authors: Sarker A , Hossain T , Bashir MN , Fatema KJ , Rahman AKML 
Published: December 2019

N, N′-bis (isatin) diamine schiff base ligands were synthesized by the condensation reaction of Isatin with various diamine (ethane-1,2-diamine, propane-1,3-diamine and hexane-1,6-diamine) in 2:1 molar ratios. These ligands were used to prepare Zr (IV) complexes. Prepared ligands and complexes were characterized by using conductance measurement, FT-IR, UV-Visible and 1HNMR spectroscopy. The presence of FT-IR band for azomethine group supports the formation of ligand. Vibrational bands for Zr←N and Zr←O in complexes signify the coordination through O and N sites of ligands. 1HNMR peak for NH moiety in ligand gets almost disappeared in complex reveals tautomerism of NH with nearby carbonyl oxygen due to the effect of complexation. The absence of peak above 500 nm in the electronic spectra indicates d0 system of zirconium in complexes. The elemental analytical data was analogous to theoretical composition of ligands and complexes. The molar conductance values obtained for the complexes represent their non-electrolytic character.

Numerical Simulation on Heat Flow for Mixed Convection Within a Triangular Enclosure
Authors: Hossain Muhammad Sajjad , Billah MM , Bangalee MZI , Alim MA 
Published: December 2019

Heat flow for laminar mixed convection in a triangular enclosure with uniformly heated bottom wall is solved using Galerkin weighted residual method of finite element formulation. A fluid with Prandtl number (Pr = 0.71) is also used to investigate the effects of heat flow for Reynolds number(40 ≤ Re ≤ 110) varying Rayleigh number (103≤ Ra ≤ 104) in that enclosure. In the enclosure, the left wall is considered cold; bottom wall is uniformly heated while the other inclined wall is insulated. The geometry of physical problems is represented mathematically by different sets of governing equations along with appropriate boundary conditions. Results are shown in terms of streamlines, isotherms, average Nusselt number and average temperature of the fluid in the cavity for uniform heating of bottom wall. It is seen that heat transfer rate from the heat source is higher for increasing value of Re. On the other hand, average bulk temperature declines significantly. It is also indicated that for fixed Prandtl number and various Ra, the buoyancy force and heat transfer rate inside the enclosure are increased for the greater value of Re.

Methodology of justification of tactical and technical requirements for movable means of repairing arms and military equipment
Authors: Dachkovskyi Volodymyr 
Published: December 2019

An analysis of the qualitative and quantitative state of mobile repair equipment, which are armed with repair units (military units), shows that the existing park consists mainly of samples that were designed in the 70's. The main disadvantage of these is the physical and moral aging and the lack of compliance with the requirements for weapons renewal systems and military equipment. Accordingly, there are drawbacks and inconsistencies between the need for repair work and the production capabilities of rolling stock.
Therefore, the article proposes a technique for substantiating the tactical and technical requirements for mobile weapons repair and military equipment operating at different levels of the hierarchy. All indicators considered in this methodology have their own specifics in the development of different types of equipment. However, they can be expressed by such groups of requirements as tactical, technical, operational, production and economic. The application of this technique will provide an opportunity to obtain technical outlines of mobile repair equipment for battalion, brigade, operational, strategic levels.
As base platforms for mobile repair tools, it is proposed to create base platforms built on a modular basis. These base platforms must allow for the placement of the control module, the power unit, the transmission module, the chassis module, in addition, the platform base must contain cells for mounting those modules to allow for the rapid replacement of damaged modules, the possibility of mounting container modules with process equipment.
For placement of technological equipment it is proposed to use bodies built on a modular principle. Assembly of such bodies with modules of technological equipment and their subsequent use will be possible depending on the intended purpose of the movable means of repair. In this case it will be possible to largely solve the problem of standardization and specialization of equipment.

Authors: Haiduk Maryna 
Published: December 2019

Англійський симфонізм доби модернізму – це глибинне, усталене в музичній культурі ХХ століття, самобутнє явище, дослідження якого є актуальним музикознавчим завданням. Мета публікації – виявити спільний образно-інтонаційний типаж у симфонічних композиціях Г. Холста, Г. Ціммера, Дж. Вільямса. За допомогою феноменологічного методологічного підходу визначаються характеристики тематичного матеріалу обраних зразків музики. Компаративний метод сприяє виявленню рис подібності, які й формують спільний образно-інтонаційний типаж. Г. Холст, засвоївши досвід симфоністів-попередників, зумів створити музичний аналог негативістського образу «сил зла», на основі якого творили композитори наступних поколінь.
До питання щодо виконавської інтерпретації образу Марфи в опері «Хованщина» Модеста Мусоргського
Authors: Belousova Tаtiana 
Published: December 2019

У статті розглянуто проблему виконавської інтерпретації партiї Марфи – головної героїні опери «Хованщина» М. Мусоргського – на прикладі творчості трьох яскравих представниць оперного вокального мистецтва середини й другої половини ХХ – початку ХХI ст. – Софії Преображенської, Ірини Архипової та Людмили Шемчук.
Мета дослідження – виявити особливості виконавського прочитання образу оперної героїні у творчості згаданих співачок на прикладі Пісні Марфи.
Актуальність роботи зумовлена відсутністю досліджень з питань специфіки виконавської інтерпретації образу героїні опери «Хованщина», попри всю очевидність щодо затребуваності таких розробок у сучасній оперній практиці.
Наукова новизна статті полягає в активізації розробки щодо вокальної сфери виконавського музикознавства на підставі об’єктивних категорій порівняльного аналізу низки інтерпретацій партії героїні опери Мусоргського. Авторка статті вперше у вітчизняному музикознавстві запропонувала класифікацію типів виконавського прочитання партії Марфи (лірико-драматичної і лірико-епічної).
Методологічною базою роботи є інтонаційна засада розуміння музики як мистецтва, тісно пов’язаного з мовленнєвою діяльністю, у традиціях школи Б. Асаф’єва, а також метод текстологічно-виконавського аналізу Пісні Марфи, основаного на графічному зображенні змісту цього номера у формі вокально-виконавської партитури ремарок.
