Tanaman sawi dipahami memiliki harga ekonomi yang tinggi mengingat sayuran ini merupakan satu diantara komoditas ekspor utama Indonesia. Namun hingga saat ini, produksi sawi belum mampu memenuhi kebutuhan pasar dalam dan luar negeri.Sistem hidroponik substrat merupakan metode budidaya tanaman di mana akar tanaman tumbuh pada media porus selain tanah yang dialiri larutan nutrisi sehingga mengharuskan tanaman memperoleh air, nutrisi, dan oksigen secara cukup. Ada beberapa jenis media tanam yang digunakan dalam sistem hidroponik substrat antara lain arang sekam, cocopeat (serbuk serabut kelapa), serbuk gergaji kayu, dan ampas tebu. Media tumbuh yang benar harus memenuhi persyaratan antara lain tidak cepat melapuk, tidak menjadi asal mula penyakit, menciptakan aerasi yang baik, mampu menyimpan air dan zat hara secara baik, mudah didapat dalam jumlah yang diinginkan dan harganya relatif murah seperti arang sekam, cocopeat, serbuk kayu, dan arang sekam. Keberhasilan penelitian ini berdasarkan sifat porus dan aerasi pada media tanam. Penelitian ini bertujuan untuk mendapatkan informasi tentang pengaruh media pada sistem hidroponik substrat pertumbuhan dan hasil sawi caisim. Penelitian dilaksanakan di lahan percobaan Jl.

Site-selective cleavage of the peptide backbone in proteins is an important class of post-translational modification (PTM) in nature. However, the organic chemistry for such site-selective peptide bond cleavages has yet to be fully explored. Herein, we report cysteine S-formylation as a means of selective protein backbone cleavage. We developed N-formyl sulfonylanilide as a cysteine-selective formylation reagent for proteins. Upon S-formylation with the reagent, the amide bond adjacent to the S-formylated cysteine is cleaved by hydrolysis under neutral aqueous conditions. Formylation probes bearing a protein ligand enabled the affinity-based selective cleavage of the target proteins not only in the test tube, but also under biorelevant conditions such as in crude cell lysate and on the cell surface. These results demonstrate the high biocompatibility of this protein cleavage technology. A proof-of-concept study of the cleavage-induced protein activation further demonstrates its utility as a platform for the functional regulation of proteins by artificial PTM.

Aim. Effectiveness and safety of levosalbutamol metered dose inhaler (MDI) in comparison with placebo and salbutamol.
Materials and methods. In this multicenter, randomized, placebo-controlled, 3-period crossover study, all asthma patients (n=91) received levosalbutamol (90 mcg), salbutamol (180 mcg), and placebo using standard MDI. Pulmonary function testing – forced expiratory volume in the first second (FEV1) and forced vital capacity (FVC) – was performed 45 and 15 minutes before and 5, 10, 15, 30, 60, 90, 120, 180, 240, 300 and 360 minutes after dosing. The primary efficacy endpoint was the baseline-corrected area under FEV1 curve from 0 to 6 hours (AUC(0–6h)). Secondary endpoints were the baseline adjusted FEV1 and FVC peak values, as well as the onset of drug action.
Results. The FEV1 AUC0–6 hours analysis confirmed similar bronchodilatory levosalbutamol and salbutamol effect (p=0.595), significantly improved compared with placebo (p0.001). The peak values of FEV1 and FVC after levosalbutamol or salbutamol dosing were similar (p=0.643) and significantly higher compared with placebo group (p0.001). The active therapy effect was observed 5 minutes after dosing and throughout the entire observation period up to 6 hours, however, there was some tendency towards a longer duration of action of levosalbutamol compared to salbutamol. Levosalbutamol was well tolerated by patients; after levosalbutamol dosing twiсе fewer adverse reactions were observed compared to salbutamol.
Conclusion. Levosalbutamol at a 90-mcg dose showed efficacy similar to that of salbutamol at a dose of 180 mcg, assosiated with a good safety profile.

Published: May 2024

In biomedical research, Electromyography (EMG) data play a crucial role as a bridge between human motions and
machine interpretation, offering valuable insights into muscle activation. EMG signals give vital information on hand
movements in the context of applications like gesture recognition, prosthetic control, and rehabilitation. This paper
describes the classification of EMG signals based on muscle motions, which makes it simpler to identify distinct gestures
or movements. A Linear Discriminant Analysis (LDA) classifier is used to differentiate between various classes of muscle
activity. In order to record EMG signals during hand motions, surface electrodes are carefully positioned on pertinent
muscles. Muscle activity may be tracked in real time with these non-invasive electrodes. In order to extract meaningful
information from these signals, which are complex and frequently contaminated by noise, strong feature extraction
techniques are needed. When working with noisy signals, denoising is a commonly used approach to restoring the
original quality of the source data. It attempts to maintain relevant information by reducing noise in the raw EMG signals.
In order to retrieve only the pertinent information from the original EMG signal data, any unnecessary noise must first be
removed. Through the identification of key characteristics in the time, frequency, and time-frequency domains, it
transforms unstructured EMG data. This procedure improves the next step of classification, which is the identification and
classification of patterns in the EMG signals. Ultimately, the obtained information is employed to classify signals by the
Linear Discriminant Analysis (LDA) classifier, demonstrating a distinction between various muscle motions with over 80%

Published: May 2024

The financial aspects of large-scale engineering construction projects profoundly influence their success. Strengthening cost control and establishing a scientific financial evaluation system can enhance the project’s economic benefits, minimize unnecessary costs, and provide decision-makers with a robust financial foundation. Additionally, implementing an effective cash flow control mechanism and conducting a comprehensive assessment of potential project risks can ensure financial stability and mitigate the risk of fund shortages. Developing a practical and feasible fundraising plan, along with stringent fund management practices, can prevent fund wastage and optimize fund utilization efficiency. These measures not only facilitate smooth project progression and improve project management efficiency but also enhance the project’s economic and social outcomes.

Authors: Ma Lili , Han Xiaolong , Gong Miao
Published: May 2024

The Lanzhou–Urumqi high-speed railway is an important part of the railway network connecting Gansu, Qinghai, and Xinjiang, and it is of far-reaching significance in facilitating China’s western development. An accessibility model and a double difference model were built to analyze the impact of the Lanzhou–Urumqi high-speed railway on regional accessibility and economic development of the areas along the line before (2012–2014) and after (2017–2019) its opening. The results show that the regional accessibility remains unchanged before and after the operation of this railway line. However, there is a spatial difference in improvement, that of central cities being better. The opening of the high-speed railway is conducive to driving the overall economic development of the region and promoting the comprehensive and coordinated development of regional economies.

Communism and Nostalgia. Longing for Communismin Texts of Publicists from Central-Eastern Europe and Balkans
Authors: Ivanov Denys
Published: May 2024

The main objective of the article is to summarize the vision of nostalgia presented in the texts of the essay collection “Nostalgia — Essays on the Logging for Communism”. The authors of these texts are Ales Debelyak (Slovenia), Dubravk Ugresic (Croatia), Fatos Lubonya (Albania), Joachim Trenkner (Germany), Yuri Andrukhovich (Ukraine), Marius Ivashkevichyus (Lithuania), Martina Shimek (Slovakia), Pavel Smolensky (Poland), Vaclav Jacques (Czech Republic), Petr Sauter (Estonia), Svetlana Boim (Russia), and others. Using content analysis, induction and deduction we found common (regional) and differing (national, personal/author`s) features of nostalgia. We showed emphasis in the narration of the authors and concluded that they describe nostalgia on a semiotic level. To define nostalgia essayists analyze nostalgia structure associated with it, material data carriers in architecture, objects of the material world and non-material data carriers — music, movie quotes, and atmosphere. We regarded using of mentioned approach as analysis of the nostalgia “language” and its manifestations. We concluded that analysis of the regional level shows the variety of manifestations of nostalgia and reactions to it — pursuing a policy of decommunization, using nostalgia for capitalist purposes (Grūtas Park in Lithuania), exploitation nostalgia for political purposes (using ideas of Great Hungary or the Kingdom of Yugoslavia). The facts of discussing nostalgia and discussing reactions to nostalgia we characterized as a discussion for the sake of discussion. We came to this conclusion based on the statement that for the person nostalgia is one of the elements of self-identification because the answer to the question “Who am I?” happens by answering the questions “How did I become this whom I am now?”, “Who was I at past?”. We used this construct to argue that the policy of mashing memory is associated with a break in the continuity necessary for self-identification.
ASSESSMENT OF NERVOUS SYSTEM STRENGTH (BRAIN EFFICIENCY) IN YOUNG TAEKWONDO ATHLETES DURING TRAINING SESSIONS
Authors: Volodymyr Sova
Published: May 2024

Introduction. The article explores the dynamics of indicators of nervous system strength (brain
efficiency) in young athletes during taekwondo training sessions, taking into account
their age and gender characteristics. The relevance and prospects of the research are
determined by the relationship between the psychophysiological properties of athletes
and their performance in taekwondo competitions, as well as the necessity of
considering this relationship in the training process.
The research aims to assess the indicators of higher nervous activity (HNA), particularly the strength
of nervous processes (brain efficiency), in young taekwondo athletes during training
sessions, considering age and gender.
Material and methods: general scientific (logical, inductive); analysis of scientific and
methodological literature and internet sources; instrumental methods (study of nervous
system strength as an indicator of brain efficiency), methods of mathematical data
processing. The indicators of nervous system strength (brain efficiency) in young
taekwondo athletes were assessed instrumentally using the PND method
(M.Makarenko).
Results. The dynamics of indicators of higher nervous activity, particularly the strength of nervous
processes (brain efficiency), were studied in 34 young taekwondo athletes, taking into
account their age and gender characteristics. Measurements were taken during training
sessions: in the warm-up phase, the main phase, and the cool-down phase. The test
results were systematized, and based on quantitative indicators, corresponding graphs
were constructed, followed by analytical evaluation.
Conclusions. The research on the dynamics of indicators of nervous system strength (brain
efficiency) in young athletes during taekwondo training sessions, considering their age
characteristics in two age groups of young taekwondo athletes, revealed that athletes
in the older age group (boys aged 13–16 and girls aged 12–15) demonstrate better
indicators of brain efficiency (fewer mistakes) compared to the younger group (boys
aged 8–12 and girls aged 8–11), presumably due to developmental age characteristics
and greater training experience. It was established that at the beginning of training
sessions, the results of girls in the younger group outperform the results of boys, while
in the older age group, boys' results are higher compared to girls. It was also found that
young athletes in both groups demonstrate the best indicators of brain efficiency in the
main part of the training session compared to the beginning and the cool-down phase.
