Published: December 2023

In order to study the effects of different amount of functional materials (FM) on pearl oil apricot, the study set up 0 g (control), 50 g (FM50), 200 g (FM200) and 300 g (FM300) of functional materials, and mixed with 2 kg of compound fertilizer as the base fertilizer. The growth and physiological indexes of pearl oil apricot and soil physicochemical properties were measured. Results showed that FM treatment significantly improved the pollen viability especially under FM300 treatment. FM200 and FM300 treatments significantly improved leaf carotenoids, anther size and anther quality of 100 seeds compared with the control. The anther width was significantly increased by 0.13 mm at FM300. However, physiological indexes such as filament length, anther length, pistil development type, hundred leaves length, hundred leaves width, hundred leaves thickness, hundred leaves weight and pollen fullness were not affected by FM. It can be seen that FM had a greater effect on growth and physiology indicators of pearl oil apricot, while the effect on soil physicochemical properties was smaller.

Authors: Zhu Jianwen , Li Juan , Ma Fei , Wang Kezhong 
Published: December 2023

The stress of the surrounding rock of hydraulic tunnel can produce a stress load on the lining body, which may cause the crack failure of the lining. The distribution and deformation characteristics play a key role in ensuring the long-term stability of tunnels. Therefore, an analysis of the distribution characteristic is of great significance. This paper takes the branch tunnel in the Yellow River Diversion Project of central Shanxi as an entity for modeling, and uses the finite difference program FLAC3D for analysis and calculation. The research results show that before the support is strengthened, the compressive stress of feet-lock bolts has exceeded the compressive strength of the bolts, with obvious stress concentration at the arch feet; the deformation mainly occurs on the vault and the bottom plate; after strengthening the support, the deformation of the steel arch prop, the axial force of the steel arch prop, and the maximum tensile stress of the anchor rods are all reduced. The stable support effect can meet the requirements of construction and later operation.

Authors: Zhao Shengzhe , Yang Yi , Chen Jinju 
Published: December 2023

The g-C3N4 nanosheets were uniformly grown on TiO2 nanotubes with porous structure via the improved methods of impregnation calcination and facial vapor deposition. The photocatalytic performance of the g-C3N4/TiO2 nanotubes was evaluated by the degradation of methyl orange solution (MO) and exhibited higher photodegradation rate than the pure g-C3N4 or TiO2 nanotubes under xenon light irradiation, which may be attributed to the increased specific surface area and efficiently separation of photon-generated electrons/holes by the heterostructure. This work provides a simple and efficient scheme of manufacturing porous heterostructure nanotubes for environmental and energy applications.

Authors: Qi Dongsheng , Zhang Yanfen 
Published: December 2023

A new left ventricular ejection index prediction method was proposed by introducing a block attention mechanism, which helps to reduce overfitting problems and improve the power of the model to process new different samples. Swin Transformer is a Transformer architecture that retains the modeling advantages of self attention mechanism. Its hierarchical design has both global and local modeling capabilities, and can output multi resolution feature maps, which is suitable for EchoCoTr's need to extract multi-scale information from time series medical images. Meanwhile, the resources required of Swin Transformer at runtime are linearly related to images to be processed, which reduces computational complexity and is suitable for processing high-resolution sequence images in EchoCoTr[1]. Swin Transformer has better results than Transformer in both classification and detection tasks, which just goes to show that it is somewhat of a great application in the field of vision. This is beneficial for EchoCoTr's understanding of cardiac ultrasound sequences. Therefore, in the original UniFormer model structure of the EchoCoTr[1] model, a new Swin Transformer Block is added. The new model has stronger modeling capabilities. This means that better results can be obtained under the same computing resources.

Published: December 2023

Bu çalışmada Salisilik asit (SA) uygulamasının, kadmiyum (Cd) stresine maruz bırakılmış buğdayın (Triticum aestivum L.) Bolal çeşidine ait yapraklarındaki apoplastik antioksidan enzim (katalaz, peroksidaz ve süperoksit dismutaz) aktiviteleri ile lipid peroksidasyonu ve hidrojen peroksit miktarı üzerine etkileri araştırılmıştır. Bitkiler 22/20 oC’de toplam 18 gün büyütülmüşlerdir. Bitki yapraklarına 12. gün farklı konsantrasyonlarda (0.01, 0.1, 1 mM) SA uygulanmış ve bundan 3 gün sonra, bitkilerin yetiştiği ortama farklı konsantrasyonlarda (25, 50, 100 μM) Cd uygulanmıştır. On sekizinci gün bitki yaprakları araştırmamızda deney materyali olarak kullanılmışlardır. SA uygulamaları, 50 ve 100 μM Cd’de katalaz (CAT) aktivitesini artırırken POX aktivitesini düşürmüştür. 25 ve 50 μM Cd’e maruz kalmış buğday yapraklarında ise SOD aktivitesini genelde artırmıştır. Ancak, 100 μM Cd’de aktiviteyi düşürmüştür. SA uygulamaları, 25, 50 ve 100 μM Cd etkisi altındaki buğdayda lipid peroksidasyonunu (LPO) düşürürken 25 μM Cd’de SA’nın 3 konsantrasyonuda H2O2 miktarını artırmıştır. SA 50 μM Cd’de H2O2 miktarını artırmıştır. 100 μM Cd’de 0.01 ve 0.1 mM SA uygulamaları aktiviteyi artırırken, 1 mM ise düşürmüştür.
Sonuçlarımız bitkilere Cd stresine maruz kalmadan uygulanan SA’nın hem apoplastik antiokdidatif enzimleri hem de LPO ve H2O2 miktarlarını düzenleyerek bir koruma sağlayabildiğini göstermektedir.

Урбанизация и рост населения в мегаполисах - общий тренд для многих стран мира. По прогнозам ООН, к 2050 году две трети жителей планеты будет проживать в городских районах. В связи с этим возникнет потребность значительного развития и перестройки городской инфраструктуры. Вместе с тем строительство выступает одним из главных факторов загрязнения окружающей среды. Помимо этого, эксплуатация возведенных объектов обходится все дороже: увеличивается стоимость энергии, ужесточаются стандарты экологической безопасности. Все это способствует активному росту интереса именно к подходам и технологиям устойчивого (зеленого) строительства.
Urbanization and population growth in megacities is a common trend for many countries of the world. According to UN forecasts, by 2050, two thirds of the world's population will live in urban areas. In this regard, there will be a need for significant development and restructuring of urban infrastructure. At the same time, construction is a major contributor to environmental pollution. In addition, the operation of constructed objects is becoming increasingly expensive: energy costs are increasing and environmental safety standards are becoming stricter. All this contributes to the active growth of interest in approaches and technologies of sustainable (green) construction.

Soil nutrient is essential for crop growth. Spatial variability of nutrients will have occurred in numerous scales, between regions, a field, particularly in soil properties. A study was carried out to observe the yield performance in an agricultural plot at Semujuk Jasin, Melaka. Using management zone delineation, the area is divided into fifteen smaller 6.8-meter × 6.8-meter plots. A soil sample from each plot was tested in the laboratory to obtain the soil moisture, organic matter, pH level, Phosphorus, and Manganese content. Using ArcGIS software, the result is interpolated using the Kringging method, mapped, and then compared with the crop value from each. Plot A3 generated the lowest yield with a crop yield value of RM6.8. This plot also has the lowest soil moisture content, which is 6.452%. Plot A1 produces only RM65.2 for crop yield, although it has 21.505% soil moisture content, while plot C1 only produces RM47.4 for crop yield value, although it has a higher soil moisture content of 23.265%. Regarding the soil organic matter content for both plots, plot A1 has only 1.455% organic matter content, while plot C1 has lower soil organic matter content, which is 0.823%. Plot B2, with a low pH value (4.51), shows a poor performance of RM52.6 regarding satisfactory readings on other plots. From the analysis made based on the experiment result, the primary limiting factor affecting crop performance is soil moisture content. Soil pH value and Organic Matter also play an essential role in determining crop performance.
