Published: April 2023

Сегодня в условиях информационного общества и сложившейся мировой демографической ситуации башни приобретают новые утилитарные функции. В небоскребах размещаются помещения практически всех типов назначения. В статье сформулировано определение Башен и Садов в современном проектном сознании, которое сложилось под влиянием техно-научного прогресса. Башня становится неким вместилищем всего социально-культурного наследия человечества. Пандемическая архитектура, пример которой также рассмотрен в статье, ярко иллюстрирует пока еще фантастическую картину того, как человек может прожить полноценную жизнь, не выходя из одного здания. На основании актуальных проблем реализации потребностей жителей крупных городов посредством архитектуры выявлены ключевые параметры объекта исследования, влияющие на формирование городской среды. Рассмотрен широкий ряд аспектов проектирования данных объектов в современных мегаполисах. Проведен пространственный и сравнительный анализ новейших проектов в парадигме «башни и сады», впервые проанализирован проект, созданный нейросетью.

Authors: ФАМ ЧУНГ ХИЕП
Published: April 2023

Реальные конструкции всегда включают технологические дефекты и особенности. К ним относят зазоры, смещения и углы отклонений деталей узлов соединений, неизбежных при сборке. Эти факторы, как правило, имеют нормативные ограничения. Для компенсации их негативного влияния на прочность узлов часто используют прием увеличения катетов сварных швов. Целью данной работы является исследование влияний перечисленных технологических факторов на прочность конструкций и разработка предложений по их учету и компенсации. Для достижения этой цели на примере внешней конструктивной защиты корпуса от грунта предложено решение задачи устойчивости пластин с разными условиями нагружения по кромкам, включая сосредоточенные силы. Рассмотрены роли и исследованы влияния перечисленных конструктивно-технологических факторов, а также катетов сварных швов на прочность конструкций. Сформулированы предложения по компенсации негативных факторов путем увеличения катетов сварных швов. Результаты работы важны как для развития методик проектирования, так и для технологий сборки и сварки судовых конструкций, работающих в экстремальных условиях

Authors: Boluwaji Oluwapelumi V. , Aro Samuel O. , Chineke Clifford A.
Published: April 2023

As a result of animal welfare issues, the use of furnished cages has been proposed. Blood viscosity and osmotic stability can be used as an indication of oxidative stress. There has, however, not been any study investigating the blood viscosity and erythrocyte osmotic stability of laying hens reared in battery and furnished cages, hence the reason for this experiment. 790 laying hens were reared in large and small furnished cages and battery cages between 14 and 60 weeks. The whole blood viscosity and erythrocyte osmotic stability were determined at the end of the experiment. The study showed that there was no significant difference in the whole blood viscosity of laying hens reared in the three cage types, while hens reared in battery cages had the highest number of stable red blood cells. This could be an indication that the stress level in the three cages is similar, while birds are more osmotically stable in the battery cages.

Published: April 2023

Millet is a prominent staple food among households in northern Nigeria; hence the bulk of its production is from the region. This study examined the technical efficiency of smallholder pearl millet farmers in north-western Nigeria. Using a sample of 430 smallholder farmers in the Kano and Jigawa states, the data for the study were collected during the 2015/2016 cropping season. Stochastic frontier analysis and least square regression were used to estimate the technical efficiency of millet farmers and to examine its determinants, respectively. The results obtained from the stochastic frontier analysis show substantial technical inefficiency among smallholder pearl millet farmers. The results reveal that all the six production variables used in the model: farm size, fertilizer, manure, labour, seed, and agrochemical, had a positive technical relationship with pearl millet output and were statistically significant. The elasticity of production, with a value of 1.83, showed that the pearl millet farmers were operating at an increasing return to scale. The result also reveals an average TE of 82 percent. The best practicing and the least technically efficient pearl millet farmers had technical efficiencies of 96 and 64 percent, respectively. In addition, in the OLS models, farmers' socio-economic factors such as farm size of farmers, type of seed planted, household size, education, access to credit, and extension contact were found to determine technical efficiency. Results of the study revealed a need for strong policies towards ensuring an efficient means of accessing farmland, labour, and improved pearl millet varieties access. Policies should also be formed to ensure easy and timely access to credit to pearl millet farmers and strengthen the extension programs for effective extension services delivery in the study area.

Investigation of In Vitro Apocarotenoid Expression in Perianth of Saffron (Crocus sativus L.) Under Different Soil EC
Authors: Mirbakhsh Mandana , Zahed Zahra , Mashayekhi Sepideh , Jafari Monire
Published: April 2023

Crocus sativus is a triploid sterile plant with red stigmas belonging to family of Iridaceae, and sub family Crocoideae. Crocin, picrocrocin, and safranal are three major carotenoid derivatives that are responsible for color, taste and specific aroma of Crocus. Saffron flowers are harvested manually and used as spice, dye or medicinal applications. The natural propagation rate of most geophytes including saffron is relatively low. An in vitro multiplication technique like micropropagation has been used for the propagation of saffron. To understand the efficiency of this alternative and study the molecular basis of apocarotenoid biosynthesis/accumulation, the RT-PCR method was performed on perianth explants that were cultured on MS medium to observe the level of expression of zeaxanthin cleavage dioxygenase (CsZCD) gene during stigma development, and also the impact of soil EC on its expression. The present study was conducted at Plant molecular and physiology Lab, Alzahra University, Tehran, Iran during 2011-2013. Stigma-like structures (SLSs) on calli were collected from immature perianth explants from floral buds of corms that were collected from Ghaen city, and compared to (Torbat-e Haidariye, Mardabad and Shahroud cities) for investigating the impact of different soil EC on CsZCD expression. The results indicated that CsZCD gene was highly expressed in fully developed red SLSs in perianth of cultured samples of Shahroud with the highest salinity. In this research, a close relationship between soil EC and second metabolites regulation is studied. Overall, these results will pave the way for understanding the molecular basis of apocarotenoid biosynthesis and other aspects of stigma development in C. sativus.

Published: April 2023

Phalaenopsis sp. is the most-produced orchid species in Indonesia. Compared to conventional breeding, mutation induction by using mutagens, such as Ultraviolet Light-C (λ = 254 nm) (UV254) and Ethyl Methane Sulfonate (EMS), could probably result in new superior orchid variants. This research aims to get some mutants with phenotypes that have visual differences in the Phalaenopsis spp. hybrids wild type. There were 4 durations of UV254 irradiation: 5’ on, 85’ off; 10’ on, 80’ off (1 day and 7 days for each treatment); 4 concentrations of EMS used in this research: 0.05%; 0.06%; 0.07%; 0.08% for 6 hours of immersion; selected UV254 irradiation (5’ on, 85’ off (7 days)) combined with these concentrations. UV254 irradiation treatment (5’ on, 85’ off (1 day and 7 days); 10’ on, 80’ off (7 days)) resulted in some mutants with leaf phenotypes that were visually different from the wild type; 0.05% EMS treatment resulted in PLBs mutant with a visually larger size than the wild type; 0.08% EMS treatment and combination treatments (for EMS 0.05% and 0.08% for each treatment) resulted in non-growing albino PLBs. Hence, mutation induction using UV254 and EMS in this research produced several most likely mutants having visual differences that may be more desirable than the wild type.

Interest Charges and the “Said” Ageing-related Expenditures: A Study of OECD Countries
Authors:   Department of public finance and taxation, University of Mons/Belgium, Philombe Zapji Ymélé Aimé
Published: April 2023

Purpose: The main objective of this paper is to evaluate whether the interest charges on public debt could be a threat for the "said" ageing expenditures. This study attempts to analyze the effects of debt burdens known as interest charges in relation to the pensions and health care spending. The "said" ageing expenditures since the debate on this issue doesn’t allow us to say that these expenses are totally linked to ageing. Design/methodology/approach: This study conducts an ordinary least squares analysis based on panel and cross-sectional data covering the period 2000-2020. The data are extracted from OECD statistic and from Eurostat statistic database. The research performs an analysis on 33 OECD countries. The dependents variables are pensions and health care spendings on GDP. The key independent variable is the interest charges. Other additional variables are included in the analysis that we can find in the text. Findings: The results of this study remain ambiguous and call for further study. Nevertheless, based on the current data, there is every reason to believe that, at present, expenditures on interest charges would not crowd out spending on pensions and health care. However, the significance of the demographic variables (old-age dependency ratio, total dependency ratio), and the increase in these ratios in the projections, point to a potential risk of collapse of the pension and health care systems. Research limitations/implications: The main difficulty encountered in this study was the collection of empirical literature dealing with our topic. Many papers used in our empirical literature was not always in relation with the topic of our research. Our challenge was to create the relation with those analyses to propose something original. Originality/value: We propose an innovative study, by proposing the analysis of debt charges in relation to pensions and health care expenditures. Several approaches in the same direction have used other parameters to analyze the costs of ageing, notably the debt to GDP ratio. We integrate other demographic variables such as the dependency ratio, macroeconomic indicators such as the savings rate. All these elements constitute the originality of our study.

Purpose: Remittance is essential to economic wellbeing. Realising this fact, this study examined, within the optimist theoretical framework, whether international remittances significantly impact per capita economic growth in Nigeria. Design/methodology/approach: Employing annual time series data spanning 1980-2020, the study adopted the Pesaran, Shin, and Smith ARDL bounds estimating model to examine the type of relationships between remittances and Nigeria’s per capita growth. Finding: The study reveals a statistically significant positive nexus in the long-run and short-run among the variables. Specifically, it found that higher remittances inflow enhances per capita growth both in long-run and short-run in Nigeria. Furthermore, the study found that remittances are sources of external financing and eventually, it is a means to economic growth and also may help to fill fiscal deficit gap. Research limitations/implications: This study recommends that government should, through sound policy option, encourage remittances influx. This could be realised by creating viable relationship among international communities that largely account for remittance inflow into Nigeria. It further suggests a prudent and optimal management of remittances inflow through the appropriate monetary authority. This may include formulating policy that will ease remittance inflow and remove unnecessary barriers to inflow of remittances. Originality/value: The study contributes to literature by examining whether international remittances within the optimist theoretical framework significantly impact per capita economic growth (PCEG) in Nigeria.
Modelling Stock Market Prices Using the Open, High and Closes Prices. Evidence from International Financial Markets
Authors:   Research associate, The IIE Vega School, South Africa, Enow Samuel Tabot
Published: April 2023

Purpose: Modelling security prices seem to be an ending debate in finance literature due to no clear consensus on behavioral patterns. Knowledge of stock price movement has always been an important source of information that is much needed in asset pricing and trading strategies. The aim of this study was to model stock market prices using six international markets as a sample. Design/methodology/approach: This study made use of the Bayesian Time-Varying coefficient for a five-year period from January 2, 2018, to January 2, 2023. Finding: The findings of this study revealed that there is strong empirical evidence that the returns of a security can be modelled using the open, high and low prices. Research limitations/implications: This implies that the drift in stock price movement can be better explained by observing the lag values of the open, high and low prices which may be an important tool for short term traders and incorporated in volatility estimation. Also, the lag values of the open, high and low price movements explain more than 98% of changes in the closing price. Originality/value: As per the author’s knowledge, this study is the first to model stock market prices using the open, high and low prices for multiple international markets.
