Authors: Stejskal Tomáš , Dovica Miroslav , Svetlík Jozef , Demeč Peter , Hrivniak Lukáš , Šašala Michal
Published: September 2020

Topology optimization is a dynamically developing area of industrial engineering. One of the optimization tasks is to create new part shapes, while maintaining the highest possible stiffness and reliability and minimizing weight. Thanks to computer technology and 3D printers, this path of development is becoming more and more topical. Two optimization conditions are often used in topology optimization. The first is to achieve the highest possible structure stiffness. The second is to reduce the total weight of the structure. These conditions do not have a direct effect on the number of elements in the resulting structure. This paper proposes a geometric method that modifies topological structures in terms of the number of truss elements but is not based on the optimization conditions. The method is based on natural patterns and further streamlines the optimization strategies used so far. The method’s efficiency is shown on an ideal Michell truss.
Influence of Coiling Temperature on Microstructure, Precipitation Behaviors and Mechanical Properties of a Low Carbon Ti Micro-Alloyed Steel
Authors: Sun Mingxue , Xu Yang , Du Wenbo
Published: September 2020

The microstructural evolution, nanosized precipitation behaviors and mechanical properties of a Ti-bearing micro-alloyed steel at different coiling temperatures were studied using optical microstructure (OM), scanning electron micrograph (SEM), transmission electron microscopy (TEM), Vickers hardness and tensile tests. When the coiling temperature was 500 °C, the specimen showed mainly bainitic structure, whereas polygonal ferrite was visible as the coiling temperature increased to 650 °C and 700 °C. The Vickers hardness of tested steel reached the maximum, which can be attributed to the largest number of nanosized precipitates in ferrite at the coiling temperature of 650 °C. A coiling temperature of 650 °C was optimal for the formation of TiC because of the high diffusion rate of alloying elements and kinetics of precipitation. In the laboratory rolling experiment, when the coiling temperature was 630 °C, the steel with yield strength of 682 ± 2.1 MPa and tensile strength of 742 ± 4.9 MPa was produced. The fine-grain strengthening and precipitation strengthening were 262 MPa and 268 MPa, respectively.

Published: September 2020

Inclusions in steels and alloys are known to lower the resistance to deformation, as well as to lower the mechanical, corrosion and other properties. Studies of inclusions in nickel-based alloys are important since these materials could suffer from corrosion degradation in harsh operational conditions. This, in fact, could lead to a pitting initiation around the inclusions. Two industrial Ni-based alloys (alloy 718 and EP718) were investigated to determine the harmful effects of different inclusions on the corrosion resistance of Ni-based alloys. Specifically, the inclusion characteristics (such as composition, morphology, size, number and location) were determined for inclusions collected on film filters after electrolytic extraction and dissolution of a metal matrix around different inclusions on surfaces of metal samples after electrolytic extraction (EE). It was found that both Ni-based alloys contain various inclusion types: carbides (large size NbTi-C and small multicomponent carbides), nitrides TiNb-N and sulphides (TiNb-S in EP718 alloy). The most harmful effects on the corrosion resistance of metal were detected around sulphides and small carbides containing Mo, W, Cr. Dissolution effects were also observed around large carbides and nitrides, especially around inclusions larger than 10 µm. Moreover, the dissolution of a matrix around inclusions and clusters located on the grain boundaries were found to be 2.1–2.7 times larger compared to inclusions found inside of grains of the given alloy samples.

Giardiasis is a diarrheal disease that is highly prevalent in developing countries. Several drugs are available for the treatment of this parasitosis; however, failures in drug therapy are common, and have adverse effects and increased resistance of the parasite to the drug, generating the need to find new alternative treatments. In this study, we synthesized a series of 2-mercaptobenzimidazoles that are derivatives of omeprazole, and the chemical structures were confirmed through mass, 1H NMR, and 13C NMR techniques. The in vitro efficacy compounds against Giardia, as well as its effect on the inhibition of triosephosphate isomerase (TPI) recombinant, were investigated, the inactivation assays were performed with 0.2 mg/mL of the enzyme incubating for 2 h at 37 °C in TE buffer, pH 7.4 with increasing concentrations of the compounds. Among the target compounds, H-BZM2, O2N-BZM7, and O2N-BZM9 had greater antigiardial activity (IC50: 36, 14, and 17 µM on trophozoites), and inhibited the TPI enzyme (K2: 2.3, 3.2, and 2.8 M−1 s−1) respectively, loading alterations on the secondary structure, global stability, and tertiary structure of the TPI protein. Finally, we demonstrated that it had low toxicity on Caco-2 and HT29 cells. This finding makes it an attractive potential starting point for new antigiardial drugs.

Authors: Yumura Masako , Nagano Tatsuya , Nishimura Yoshihiro
Published: September 2020

In recent years, multitarget drugs for neurological diseases such as Alzheimer’s disease have been developed and well researched. Many studies have revealed that multitarget drugs are also useful for lung cancer and respiratory diseases. Pemetrexed is a multitargeted antifolate with strong antitumor activity against mesothelioma and lung adenocarcinoma. Crizotinib is an ATP-competitive tyrosine kinase inhibitor that targets c-MET, ROS1, and ALK. Alectinib is known as an ALK inhibitor but also targets LTK, CHEK2, FLT3, PHKG2, and RET. Sorafenib is a tyrosine kinase inhibitor that targets RAF kinase, KIT, VEGFR, PDGFR1β, FLT3, and RET. Nintedanib is a multiple tyrosine kinase inhibitor that targets FGFR, PDGFR, and VEGFR. In this review, we summarize the mechanisms of action of multitarget therapies and report the results of the latest clinical trials.
The Role of Specific Components of a Plant-Based Diet in Management of Dyslipidemia and the Impact on Cardiovascular Risk
Authors: Trautwein Elke A. , McKay Sue
Published: September 2020

Convincing evidence supports the intake of specific food components, food groups, or whole dietary patterns to positively influence dyslipidemia and to lower risk of cardiovascular diseases (CVD). Specific macro- and micro-components of a predominantly plant-based dietary pattern are vegetable fats, dietary fibers, and phytonutrients such as phytosterols. This review summarizes the current knowledge regarding effects of these components on lowering blood lipids, i.e., low-density lipoprotein cholesterol (LDL-C) and on reducing CVD risk. The beneficial role of a plant-based diet on cardiovascular (CV) health has increasingly been recognized. Plant-based dietary patterns include a Mediterranean and Nordic diet pattern, the dietary approaches to stop hypertension (DASH), and Portfolio diet, as well as vegetarian- or vegan-type diet patterns. These diets have all been found to lower CVD-related risk factors like blood LDL-C, and observational study evidence supports their role in lowering CVD risk. These diet patterns are not only beneficial for dyslipidemia management and prevention of CVD but further contribute to reducing the impact of food choices on environmental degradation. Hence, the CV health benefits of a predominantly plant-based diet as a healthy and environmentally sustainable eating pattern are today recommended by many food-based dietary as well as clinical practice guidelines.
Abalone Viral Ganglioneuritis
Authors: Corbeil Serge
Published: September 2020

Abalone viral ganglioneuritis (AVG), caused by Haliotid herpesvirus-1 (HaHV-1; previously called abalone herpesvirus), is a disease that has been responsible for extensive mortalities in wild and farmed abalone and has caused significant economic losses in Asia and Australia since outbreaks occurred in the early 2000s. Researchers from Taiwan, China, and Australia have conducted numerous studies encompassing HaHV-1 genome sequencing, development of molecular diagnostic tests, and evaluation of the susceptibility of various abalone species to AVG as well as studies of gene expression in abalone upon virus infection. This review presents a timeline of the most significant research findings on AVG and HaHV-1 as well as potential future research avenues to further understand this disease in order to develop better management strategies.

Puumala virus (PUUV) in Europe causes nephropathia epidemica (NE), a mild form of hemorrhagic fever with renal syndrome (HFRS). The incidence of NE is highly heterogeneous spatially, whereas the geographic distribution of the wild reservoir of PUUV, the bank vole, is essentially homogeneous. Our understanding of the processes driving this heterogeneity remains incomplete due to gaps in knowledge. Little is known about the current distribution and genetic variation of PUUV in the areas outside the well-identified zones of NE endemicity. We trapped bank voles in four forests in French regions in which NE is considered non-endemic, but sporadic NE cases have been reported recently. We tested bank voles for anti-PUUV IgG and characterized the S segment sequences of PUUV from seropositive animals. Phylogenetic analyses revealed specific amino-acid signatures and genetic differences between PUUV circulating in non-endemic and nearby NE-endemic areas. We also showed, in temporal surveys, that the amino-acid sequences of PUUV had undergone fewer recent changes in areas non-endemic for NE than in endemic areas. The evolutionary history of the current French PUUV clusters was investigated by phylogeographic approaches, and the results were considered in the context of the history of French forests. Our findings highlight the need to monitor the circulation and genetics of PUUV in a larger array of bank vole populations, to improve our understanding of the risk of NE.

Agricultural Greenhouses Detection in High-Resolution Satellite Images Based on Convolutional Neural Networks: Comparison of Faster R-CNN, YOLO v3 and SSD
Authors: Li Min , Zhang Zhijie , Lei Liping , Wang Xiaofan , Guo Xudong
Published: September 2020

Agricultural greenhouses (AGs) are an important facility for the development of modern agriculture. Accurately and effectively detecting AGs is a necessity for the strategic planning of modern agriculture. With the advent of deep learning algorithms, various convolutional neural network (CNN)-based models have been proposed for object detection with high spatial resolution images. In this paper, we conducted a comparative assessment of the three well-established CNN-based models, which are Faster R-CNN, You Look Only Once-v3 (YOLO v3), and Single Shot Multi-Box Detector (SSD) for detecting AGs. The transfer learning and fine-tuning approaches were implemented to train models. Accuracy and efficiency evaluation results show that YOLO v3 achieved the best performance according to the average precision (mAP), frames per second (FPS) metrics and visual inspection. The SSD demonstrated an advantage in detection speed with an FPS twice higher than Faster R-CNN, although their mAP is close on the test set. The trained models were also applied to two independent test sets, which proved that these models have a certain transability and the higher resolution images are significant for accuracy improvement. Our study suggests YOLO v3 with superiorities in both accuracy and computational efficiency can be applied to detect AGs using high-resolution satellite images operationally.
An Advanced Edge-Detection Method for Noncontact Structural Displacement Monitoring
Authors: Bai Xin , Yang Mijia , Ajmera Beena
Published: September 2020

A non-contact vision sensor system for monitoring structural displacements with advanced Zernike subpixel edge detection technique is suggested in this paper. Edge detection can detect features of objects effectively without using templates. Subpixel techniques provide more accurate and cost-effective results when compared to integer pixel methods. Built on these two techniques, a new version sensor method was developed to detect the vibrations of structures in this study. Satisfactory agreements were found between the displacements measured by the vision sensor system and those recorded by the Multipurpose Testing System (MTS). A field test was then carried out on a street sign using the proposed vision system. Satisfactory results were obtained using the new version of the sensor system at many points simultaneously without any manually marked targets. Moreover, the system was able to provide natural frequencies and mode shapes of the target instantaneously, which could be used to accurately locate damage.

Satellite geodetic networks are commonly used in surveying tasks, but they can also be used in mobile surveys. Mobile satellite surveys can be used for trackage inventory, diagnostics and design. The combination of modern technological solutions with the adaptation of research methods known in other fields of science offers an opportunity to acquire highly accurate solutions for railway track inventory. This article presents the effects of work carried out using a mobile surveying platform on which Global Navigation Satellite System (GNSS) receivers were mounted. The satellite observations (surveys) obtained were aligned using one of the methods known from classical land surveying. The records obtained during the surveying campaign on a 246th km railway track section were subjected to alignment. This article provides a description of the surveying campaign necessary to obtain measurement data and a theoretical description of the method employed to align observation results as well as their visualisation.

Published: September 2020

Population ageing is having a direct influence on serious health issues, including hampered mobility and physical decline. Good habits in performing physical activities, in addition to eating and drinking, are essential to improve the life quality of the elderly population. Technological solutions, aiming at increasing awareness or providing reminders to eat/drink regularly, can have a significant impact in this scenario. These solutions enable the possibility to constantly monitor deviations from users’ normal behavior, thus allowing reminders to be provided to users/caregivers. In this context, this paper presents a radio-frequency identification (RFID) system to monitor user’s habits, such as the use of food, beverages, and/or drugs. The device was optimized to fulfill specifications imposed by the addressed application. The approach could be extended for the monitoring of home appliances, environment exploitation, and activity rate. Advantages of the approach compared to other solutions, e.g., based on cameras, are related to the low level of invasiveness and flexibility of the adopted technology. A major contribution of this paper is related to the wide investigation of system behavior, which is aimed to define the optimal working conditions of the system, with regards to the power budget, user (antenna)-tag reading range, and the optimal inter-tag distance. To investigate the performance of the system in tag detection, experiments were performed in a scenario replicating a home environment. To achieve this aim, specificity and sensitivity indexes were computed to provide an objective evaluation of the system performance. For the case considered, if proper conditions are meet, a specificity value of 0.9 and a sensitivity value of 1 were estimated.
Altered Self-Observations, Unclear Risk Perceptions and Changes in Relational Everyday Life: A Qualitative Study of Psychosocial Life with Diabetes during the COVID-19 Lockdown
Authors: Grabowski Dan , Meldgaard Julie , Hulvej Rod Morten
Published: September 2020

When the Danish society went into COVID-19 lockdown, it dramatically changed the conditions for living with a chronic disease like diabetes. The present article highlights the psychosocial effects of this change. The dataset consists of 20 semi-structured online interviews with people with diabetes. The data were analyzed using radical hermeneutics and interpreted using Luhmann’s operative constructivist systems theory. The analysis produced three main themes: (1) people with diabetes experience altered self-observations–mainly due to society labelling them as vulnerable, (2) people with diabetes have unclear risk perceptions due to lack of concrete knowledge about the association between COVID-19 and diabetes, and (3) changes in conditions for maintaining and creating meaningful relations have a significant impact on everyday life with diabetes. These findings have important implications for risk communication. People respond in a multitude of ways to communications issued by health authorities and with close relations, and their meaning-making is shaped by, and shapes, their self-observations, risk perceptions and relational environments. This calls for more targeted communication strategies as well as increased use of peer support; the goal being to help people create meaning in their own environments.
Comparative characteristics of population and genetic parameters of Syrian cattle breed Shami with Holstein and Aberdeen-Angus
Authors: Kostomakhin N. , Mohammad A. , Bakai A.
Published: September 2020

The material on the widespread use of Holstein cattle breed in the Syrian Arab Republic to improve local breeds has been presented in the article. The analysis of the genetic equilibrium of individual loci in Syrian cattle breed Shami has been revealed a deviation from the equilibrium of four loci: TGLA227, SPS115, TGLA122 and ETH225, in Holstein breed one locus SPS115, in Aberdeen-Angus breed two loci TGLA122 and ETH225. When assessing the level of genetic consolidation, a defi ciency of heterozygotes has been noted in two of the three breeds studied: 4,8 % in Shami and 8,0 % in AberdeenAngus. In Holstein breed a slight excess of heterozygotes at the level of 0,2 % has been revealed. The calculation of the value of the fixation index (Fis) has shown an excess of heterozygotes only in the loci TGLA227, INRA23, TGLA126 and as a consequence a positive average value collectively for the studied samples of cattle at the level of 5,8 %. The average Fst at 11 loci for all breeds was 0,069, indicating that 93,1 % of all variability is due to intra-breed diversity and only 6,9 % to inter-breed differences. The analysis of animals belonging to their own breed has shown 100 % genetic consolidation and compliance of the studied individuals with their breeds. The analysis of genetic distances adjusted for small samples has revealed the smallest genetic distance between Shami and Holstein breeds 0,107. Aberdeen-Angus breed, which has a separate origin and has not been imported into the Syrian Arab Republic, is adjacent to this cluster an independent branch.
Stenogrammitis myosuroides (Polypodiaceae): a new addition to the European flora from southwest Ireland
Authors: Hodd Rory , Rumsey Fred
Published: September 2020

The occurrence of the fern Stenogrammitis myosuroides (Sw.) Labiak in Europe is reported for the first time. A small population was discovered on two boulders beside a stream in Atlantic oak woodland in the Killarney National Park, Co. Kerry, in southwest Ireland. The main identification features of this taxa and features that distinguish it from other similar taxa are laid out and discussed. S. myosuroides is elsewhere known to occur in the Neotropics, in Cuba, Jamaica and the Dominican Republic, and is thought to have colonised its Irish site through long-distance spore dispersal. Two Grammitid species of similar ecology have been discovered in the Azores in the past five decades and a number of bryophyte species share a similar disjunct distribution between Ireland and the Neotropics, all of which supports the theory that long-distance dispersal is the most plausible explanation for the occurrence of S. myosuroides in Ireland. It is not clear how long S. myosuroides has been present in Ireland, although morphological differences suggest that it may have been separated from the Neotropical populations for a long period. However, molecular analysis is required to elucidate this.

A novel hybrid of Hypericum undulatum (Wavy-leaved St. John’s-wort, Hypericaceae) and its subsequent dispersal
Authors: Jones Andrew , Rumsey Fred
Published: September 2020

The novel hybrid Hypericum undulatum Schousb. ex. Willd. x H. perforatum L. is described from Cardiganshire (v.c.46) and given the name H. x cereticae R.A. Jones, F.J. Rumsey & N. Robson.  Despite reduced fertility it shows indications of ongoing introgression and signs of recent dispersal up to 5 km from the core site. The hybrid has arisen recently at the northern extremes of the rarer (H. undulatum) parental species’ range, although at neither site are the parents currently sympatric and in the outlying population both are absent, supporting the belief that here it has not arisen de novo but has colonised through unknown agencies.

Published: September 2020

The range of educational services is really wide. The main reasons and goals of people's universities are as follows: the formation of knowledge, the formation of beliefs, the formation of will, the formation of man. Its motivation is a return to rationalism in everyday life and "concern" for the irrational. The establishment of adult education centers is an opportunity to promote democracy. Such education forms an awareness of the political, social and cultural that can serve as the basis for a true revival of European values.
The modern globalized world needs a democratic education that is not limited to national borders and the national idea. For a commonly desired future, there is a need for a broader, panoramic and forward-looking view of European values and the integrative content of European culture. Adult education centers work with traditional universities, non-governmental organizations, local associations to unite society, unite the community for a fairer and more stable social life. Such centers perform the functions of integration and translation of cultural values, universal values of humankind, teach people to be effective in the unity of diversity: uniting people of different talents, competencies and skills into an effective organism of social order.

Halk sağlığının ana kavramlarından biri olan “korumak tedaviden hem üstün hem de ucuzdur” ilkesi, Koronavirüs (COVİD-19) sonrası yeni dünya sağlık politikaları açısından adından sıkça söz ettirecektir. Zira devletlerin ülke sağlık politikalarında koruyucu önlem politikalarını yerine getirmemiş olmaları, COVİD-19 sonrası Avrupa örneğinde olduğu gibi ilk 3 haftada yüksek yıkıcı sonuçlara yol açmıştır (sağlık personelinin maskeye-koruyucu malzemelere ulaşamaması, sağlıklı bireylerin yeterli maskeye ulaşamamış olmaları, hastaların yeterli sağlık hizmetlerini bulamaması). Koruyucu önlemlere yönelik tedbirlerin alınmamış olması tek başına tedavi edici sağlık hizmetlerinin, COVİD-19 gibi şiddetli-yıkıcı-yayılmacı salgın hastalıklar anında işe yaramayacağını ortaya koymaktadır. Zira salgının ilk dalgasında görüldü ki kişisel koruyucu önlemlere sahip olmayan dünya nüfusu, kısa süre içerisinde semptomatik veya presemptomatik olarak hastalığa sahip olma ve hastalığı yayma konusunda ilki hayvandan insana geçme durumundan daha sonra başlı başına tamamen hastalığın konakçısı oluverdiler. COVİD-19’ un gelecek yüzyılda alışılagelmiş koruyucu önlemlerin (kişisel ve çevresel) önemini daha fazla genişleteceği aşikardır. Bu durum bundan sonra insan yoğunluğunun fazla bulunduğu yerlerde maske kullanımının normal kabul edileceği, taşınabilir el dezenfektanlarının kullanılacağı, daha önce alışılagelen sabun ile ellerin sık sık yıkanması kişisel koruma önlemleri vb. pek çok örneklerin çok güçlü davranış değişikliklerine yol açacağını ortaya koymaktadır. Hükümetlerin COVİD-19 sonrası koruyucu sağlık önlemleri konusunda politika değişikliğine giderek, ilkokullardan başlayarak tüm nüfusu etkisi altına alacak kalıcı tedbirleri almaları gerekmektedir.
Teaching Crafty Microbiology: Safely Teaching Hands-on Microbiology Skills at Home
Authors: Estes Anne , Jozwick Anna K.S. , Kerr Jennifer E.
Published: September 2020

Using non-toxic craft items and disposable lab consumables, we have developed nine modules to teach fundamental, hands-on microbiology lab skills safely at home. These ‘Crafty’ teaching modules can be paired with virtual instruction and/or data collected by an instructor to replicate traditional unknown microbiology lab exercises. Materials and procedures used were carefully chosen to best mimic the texture of ‘media,’ represent microbial ‘diversity,’ assess aseptic technique, and produce analyzable data from results. Some protocols build upon and extend previously unpublished ideas, while others provide novel methods. The lab skills include proper PPE usage and basic biosafety, aseptic technique, microscopy and staining, streaking for isolation, spread plating, serial dilutions, filtering, disk diffusion method, and modeling an epidemic. Each protocol includes a student handout with background, links to videos of the methods performed with microbes, a rationale for the pairing of craft and consumable lab supplies along with technique used, a video/image demonstration of the ‘Crafty’ technique when needed, post-lab questions, and an instructor guide. This resource was developed for an undergraduate microbiology course and each lab is aligned with learning outcomes within American Society for Microbiology’s undergraduate curriculum guidelines. This work would also be useful for outreach and K-12 educators. The development of microbiology lab skills by all students, regardless of economic or health status, will lead to a more scientifically minded society.

dimensão originária das vivências musicais em capoeira
Authors: Valério Pedro Henrique Martins , Barreira Cristiano Roque Antunes
Published: September 2020

O objetivo deste trabalho é compreender os sentidos inerentes à musicalidade vivida em capoeira. Para tanto, se procede seguindo os passos de Edmund Husserl (1859-1938) no enquadre de uma arqueologia fenomenológica das culturas. Os relatos de mestres de capoeira, produzidos sob escuta suspensiva e transcritos, foram analisados mediante sucessivos cruzamentos intencionais. Muitos mestres relatam o atravessamento desta experiência musical que, desde um registro pré-reflexivo, conduz à ação seus corpos durante o jogo. Os resultados descrevem uma afecção musical crucial que inaugura intersubjetivamente uma abertura corpóreo-psíquica aos sentidos dos acontecimentos da roda. Tal abertura se mostra no compartilhar pré-reflexivo de sentimentos próprios à capoeira, em que capoeiristas manifestam-se de modo cultural e existencialmente autêntico. Aprofunda-se a análise à luz do diálogo com a literatura destacando-se a operatividade intersubjetiva da dimensão psíquica no corpo a corpo em ação, articulando-se com as investigações de Husserl sobre o substrato originário das experiências do Outro.

Two experiments were conducted at (i) irrigated lowland, village of Bojong, Cikembar, Sukabumi Sub-district, Indonesia, from November 2011 to February 2012, and (ii) rain-fed lowland, village of Sanca, Gantar sub-district, Indramayu, Indonesia, from April to July 2012. The objective of the experiment was to determine the yield of drought-tolerant hybrid rice genotypes. A randomized block design with three replications was used. The treatment consisted of 8 hybrid rice genotypes (BI485A/BP3, BI485A/BP5, BI485A/BP10, BI485A/BP12, BI485A/BP15, BI599A/BP5, BI599A/BP15 and BI665A/BP6) and 2 check varieties (Hipa 7 and Ciherang) for the experiment in irrigated lowland, 4 hybrid genotypes (BI485A/BP3, BI485A/BP12, BI485A/BP15 and BI599A/BP15) and 3 check varieties (Hipa 7, IR64 and Limboto) for the experiment in rain-fed lowland. On irrigated lowland, all tested-genotypes produced grain yield per hectare, which was not significantly different from the check varieties Ciherang and HIPA 7. The yield of genotype BI485A/BP12, BI485A/BP15 and BI559A/BP15 under irrigated lowland showed non-significant different with check varieties Ciherang and Hipa 7, i.e 5.63, 6.87, and 6.30 tons ha-1, respectively. Genotype BI599A/BP15 under severe drought rain-fed lowland yielded 0.90 tons of grain ha-1, whereas Hipa 7 (hybrid variety, suitable for rain-fed lowland) and Limboto (drought-tolerant check variety) reached 0.34 and 0.29 tons ha-1, respectively. Genotype BI599A/BP15 is a new hybrid genotype that potential for advanced development in rain-fed lowland and in irrigated lowland with a high yield potential and quiet early-maturity age.
