Authors: Homon Sviatoslav , Matviiuk Oleksandr , Kulakovskyi Leonid , Chornomaz Nataliya 
Published: May 2022

An analysis of publications on this topic. It is established that in most literature sources the work of wood is shown only in the ascending branch of deformation, which is a false statement. The method of experimental studies of alder and spruce wood by axial compression along the fibers with a short-term load at standard humidity (by increasing displacements) is presented. The age of the wood was about 40 years. Experimental studies of such samples were performed on a modern STM- 100 test machine. 18 samples with a cross section of 30x30x120 mm were tested. Based on the experiment, complete deformation diagrams “stress σc - strain uc” were constructed and the main parameters were established: critical and residual strains, as well as their corresponding stresses. It is established that both diagrams have an ascending and descending branch, ie they work in both pre-critical and super-critical stages of work.
The average critical deformations of alder wood uc,0,d = 0,00397, as well as the corresponding maximum stresses fc,0,d = 35,6 MPa, and spruce wood - uc,0,d = 0,00421 (fc,0,d = 38.1 MPa).
Also, the average residual deformations for alder wood uc,fin = 0.277, and the corresponding stresses σc,fin = 3.9 MPa; for spruce wood uc,fin = 0.212, and stress - σc,fin = 3.6 MPa.
It is confirmed that deciduous and coniferous wood at standard humidity has an ascending and descending branch, ie works in the subcritical and supercritical stages of work.
In the future it is necessary to conduct such experimental studies for other deciduous and coniferous species. In the future, determined mechanical characteristics experimentally, it is necessary to propose methods for finding and theoretical, which will give a complete picture of such materials.

Published: May 2022

This study empirically evaluated the effect of monetary policy rate (MPR) on Nigeria’s economic growth using annual data spanning 2006 - 2020. The technique adopted in this paper is a simultaneous equation model using two Stage Least Squares (2SLS). Variables of interest were Broad money supply as a ratio of GDP (M2/GDP), Credit to the private sector as a ratio of GDP (CPS/GDP), Cash reserve ratio (CRR), Liquidity ratio (LQR), and Lending interest rate (LIR). The preliminary unit root test revealed stationarity at first difference. The weak instrument test result shows a robust instrument at 10 and 20 per cent. While the residual result indicates an absence of heteroskedasticity in the model. The findings revealed that monetary policy rate has a negative but significant effect on economic growth, Real Exchange Rate (REXR) has an inverse relationship and significant effect on economic growth while inflation (INFL) has a negative and insignificant impact on economic growth. Given that monetary policy rate significantly impacts economic growth in Nigeria, the paper recommended that the Central bank of Nigeria should ensure that the fixing of the monetary policy rate is such that it enables the flow of credit in the desired direction to boost investment and economic activities in the economy; by identifying the Monetary Policy Rate threshold that is suitable for price stability, investment and output growth.

Authors: Octauria Emilia Putri , Nindito Dwi Anung , Saputra Raden Haryo 
Published: May 2022

<p>Energi terbarukan bisa digunakan sebagai solusi mengurangi ketergantungan pada bahan bakar fosil dengan cara menggunakan sumber hidroelektrik seperti penggunaan turbin vertikal berjenis Darrieus. Turbin Darrieus memiliki kelemahan yaitu kesulitan memulai awal putaran (<em>self starting</em>) pada rotornya karena berbasis gaya angkat. Studi ini menyelidiki pengaruh penambahan pengarah <em>Omni Directional Guide Vanes</em> (ODGV) dengan jumlah <em>guide vanes</em> dan besar sudut berbeda-beda terhadap turbin Darrieus dengan tujuan dapat menekan kelemahannya. Studi ini menggunakan turbin Darrieus 2 (dua) airfoil dan 3 (tiga) airfoil dengan profil NACA 0012 untuk diujikan di aliran air pada saluran prismatik. Hasil uji eksperimental menunjukkan bahwa penggunaan pengarah dengan perbandingan 1/6 celah ODGV (6 <em>guide vanes</em>) dan sudut 0º mengakibatkan bertambahnya nilai <em>Coefficient of Power </em> (C<sub>p</sub>) dan nilai <em>Tip Speed Ratio</em> (TSR), sehingga mampu meningkatkan Cp rata-rata lebih besar 34,25% dari turbin Darrieus konvensional. Namun seiring bertambahnya jumlah <em>guide vanes</em> dan besar sudut membuat performa turbin menurun. Pengarah ODGV mampu meningkatkan nilai TSR sehingga dapat mengoptimalkan gaya angkat pada turbin.</p>

Published: May 2022

Background: Diagnosis is a key determinant for any disease outcome. For that, we want to find out in which stage a breast cancer patient got admitted in hospital including various methods of laboratory investigations were done at different visits.
Objectives: This study was aimed to generate information on the stages that a breast cancer patient got admitted including various methods of laboratory investigations were done at different visits.
Methodology: We conducted a cross sectional study at the National Institute of Cancer Research and Hospital, Dhaka, Bangladesh from July 2017-June 2018. We randomly selected a total of 200 patients who came to that hospital through face-to-face interview by using pretested semi-structured questionnaire.
Results: A total 77.0% (154) patients investigated Fine Needle Aspiration Cytology (FNAC) at first visit and mean duration for diagnosis was 11 months. Maximum patients came for diagnosis at stage II, III or IV; nobody came at stage I. As consequences, we found that stage of cancer had 7 times more likely to cause diagnostic delay (OR=7.957; 95% CI 3.206-19.749) p <0.0001. Number of consultations was one of the cause for diagnostic delay (c2= 12.825, p <0.0001). Diagnostic delay had strong association between first consultation with physician versus other health care providers (c2= 17.645, p <0.0001). Excluding physicians, first consultation with health care providers also had 3 times more likely to cause delay in diagnosis (OR-3.862; 95% CI1.877-7.944) p<0.0001.
Conclusion: Breast cancer patients attended to health care provider at advanced stage. Knowledge, negative perception, social support were the contributing factor for delay in breast cancer diagnosis.
