In this work, the results of a detailed sound monitoring conducted during December 2023 in the mountain rainforest of Yungas (750 meters above sea level), in the vicinity of Piedras stream within the protected area of Sierra San Javier Park, are presented. The spectrograms obtained from the inner forest differ consistently from those of the riparian forest, distinguishable by their bioacoustic characteristics. It is conjectured that the stream, through its geophonic load and ecological imprint on the landscape, imposes restrictions on the occupation of the ecoacoustic niche by the fauna ensemble present in the area.

Aim. To evaluate tolerability, safety and efficacy of target products used in the treatment of cystic fibrosis (CF) in children. Design. Retrospective and prospective comparative study. Materials and methods. The study included 12 patients aged 3 to 18 years old with complete genetic analysis of CF, which can be treated with target therapy (TT), and a chronic bronchopulmonary process. Seven children were treated with a two-component drug and five children — with a three-component drug. A control group included 12 patients with CF, but not treated with TT; the groups were similar in age and sex and had mutations of respective classes. All subjects underwent clinical, laboratory and instrumental tests and assessments. Condition was monitored at baseline, in 2 weeks, 1, 3, 6 months. Results. At baseline, the majority of patients had minor complaints which resolved without any intervention. Adverse effects, which required drug discontinuation, were recorded in one patient treated with the two-component drug. Patients, who received the three-component therapy, had significant improvement in nutritional status, marked and stable reduction in sweat test values. Conclusion. Modern TT for CF is well-tolerated, quickly improves patients' state, especially when a three-component drug is used. Subjective perception of improved breathing function, reported by patients, was not confirmed with pulmonary function test results and requires monitoring in a larger population. Keywords: cystic fibrosis, target therapy, children.

Aim. To study peculiarities and to optimise the micro- and macroelemental status of children during the first year of life, the prenatal development of which fell at a military conflict. Design. Phase one was a retrospective analysis of medical documents (medical history of a pregnant woman, labour and delivery medical record, infant's record; phase two was comparison of the elemental composition of children's hair. Materials and methods. The study included 154 children less than a year of age: prenatal development of 81 children fell at a military conflict (study group) and 73 children — during the time of peace (controls). Children in both groups were formula-fed as their mothers had agalactia because of stress caused by military actions. Elemental composition of children's hair was determined using an AAC 2280 Perkin Elmer atomic absorption spectrophotometer (USA); identified diselementosis was corrected with introduction of an adapted and enriched formula, and the analysis was repeated in 6 months. Results. The first analysis revealed imbalance in micro- and macroelemental composition of children's hair in the study group: lower levels of iron, copper, selenium, magnesium, zinc, manganese and potassium, as well as accumulation of toxic elements — lead, cadmium, chrome. A repeated analysis showed significant optimisation of essential micro- and macroelements, as well as reduction in the level of toxic microelements in children's hair. Conclusion. Prenatal development during an active military conflict causes diselementosis, which leads to somatic pathologies in children of both neonates and infants. An optimal formula makes it possible to correct elemental imbalances during the first year of child's life. Keywords: diselementosis, essential and toxic elements, correction.

Published: July 2024

In today's time, increasing infection and resistance to an antibiotic is hazardous for the community. Every year, millions of people die as a result of bacterial illnesses around the world. Evolution in resistance has reduced the effectiveness of antibacterial drugs or made these drugs ineffective. This investigation aims to evaluate the antimicrobial potential of polymeric metal chelates of PATHQ with UO2 +2 metal ions on some gram -ve and gram +ve microorganisms. In recent work, uranyl (UO2) +2 novel compounds were synthesized from polyamine-s-triazine5-amino-8-Hydroxyquinoline (PATHQ) and anti-microbial analysis was done by a zone of inhibition method. Mueller–Hinton agar was prepared and used for analysis. Antibacterial studies have been performed with 100 ppm concentration on different types of microorganisms i.e., B. megaterium, S. aureus, P. aeruginosa and E.coli.The plates were incubated at 32.5 ± 2.5oC for 18 to 24 hours in an incubator. The results showed that the remarkable inhibition of bacterial growth was shown against the all-tested organisms. The microbial activity of the compound was due to the presence of UO2+2 metal ions. Hence, these compounds can be leads in the development of new pharmaceutical research activities.

Demografische Entwicklung in der Waldwirtschaft – Chance oder Damoklesschwert?
Authors: Janssen Simon
Published: July 2024

Die Schweizer Forstwirtschaft steht vor einer Pensionierungswelle. Doch ist dies ein Problem? Bereits in den 1980er-Jahren war die Rede von einem bevorstehenden Mangel an ausgebildeten Forstleuten. Die Zahl der jährlich neu ausgebildeten Forstwarte ist seither stabil. Ebenso die Abwanderung in andere Branchen. Bleiben die Bewerbungen auf eine ausgeschriebene Stelle aus, sollten wir uns zuerst einmal mit unseren eigenen Strukturen befassen. Sowohl für Lernende als auch ausgebildete Forstwartinnen und Forstwarte sind die Entwicklungsmöglichkeiten wichtig. Gleichzeitig gewinnt die Möglichkeit einer flexiblen Arbeitszeitgestaltung an Bedeutung. Eine ausgereifte Stellvertretungsregelung hilft, diesen Ansprüchen gerecht zu werden. Viele Forstbetriebe arbeiten heute an der Schnittstelle zwischen Forst und anderen Branchen. Die Arbeit wird vielfältiger, und es kann Personal integriert werden, das ursprünglich aus anderen Berufen stammt. Die personelle Diversität erleichtert die Aufgabenzuteilung im Betrieb und die interne Weiterbildung. Die anstehende Pensionierungswelle bietet Chancen für jüngere Mitarbeitende, die heute vom Wissen älterer Forstprofis profitieren und dieses später selbstständig weiterentwickeln können.

In order to solve the problem that the spatial structure and temporal dynamic structure of skeletal data are not clearly and fully utilized when using hand bone data for action recognition, a spatio-temporal synchronous graph convolution network with combined attention mechanism is designed. Using the method of 2D estimation and triangulation, the feature is projected into a single 3D volume, the 3D heat map is output, and the 3D joint coordinates are obtained by soft-argmax operation on the heat map. The spatial dimension and the temporal dimension of the bone data are separated, the spatial dimension is encoded according to the order of the related nodes, and the same related nodes are encoded in the temporal dimension, and the spatial embedding matrix and the temporal embedding matrix are obtained. The matrix is synchronously added to the spatio-temporal network sequence. The experiment is tested on the SHREC2017 data set, and compared with some representative gesture recognition methods, the results show that the algorithm has achieved good results in hand action recognition.
Battery State of Charge Estimation Utilizing Time Serialized Convolutional Neural Networks in Complicated Working Conditions

Determining the State of Charge (SOC) is crucial in battery management systems, guaranteeing the safety and dependability of the battery. The conventional approach to estimating battery SOC, which relies on neural networks, typically involves utilizing the terminal voltage and current measurements obtained under ideal conditions. The SOC of a battery is not readily quantifiable. It may be estimated by assessing numerous metrics, including battery terminal voltage, charging and discharging current, internal resistance, and other pertinent aspects. Precisely estimating battery SOC under intricate operational circumstances is presently a major concern. The absence of a direct relationship between the data derived from significant variations in current and voltage is the underlying cause. As a result, the conventional Backpropagation Neural Networks (BPNN) exhibits a significant mistake in SOC prediction. Given the aforementioned issues, this paper proposes using Time Serialization Convolutional Neural Networks (TSCNN) to solve the problem that, under complex working conditions and traditional BPNN, it cannot improve the precision of battery SOC estimation.The empirical findings indicate that the Urban Dynamometer Driving Schedule (UDDS) dataset has a maximum error of 4.39%. Similarly, the dynamic stress test (DST) dataset demonstrates a maximum error of 6.26%. Therefore, the TSCNN model proposed in this research exhibits the capability to significantly boost the precision and dependability of battery SOC estimates under complex working conditions.

Precisely estimating the battery State of Charge (SOC) can maximize the utilization of battery energy and reduce energy consumption. The tradition neural network-based battery SOC estimation methods have a common defect, that is, the input of the model is a continuous constant current or a periodic current that does not change drastically under normal power. These traditional methods are not accurate when the battery is in a low power condition. Aiming at the above problems, this paper proposed a battery SOC estimation method based on a gated recurrent unit recurrent neural network with self-attention mechanism (GRU-Attention) under low power. Firstly, to validate the new method, experiments were conducted using datasets from real battery tests. Then, preprocess the data by serializing the discharge data of the battery. Finally, these data are input into the GRU-Attention model for training. The experimental results indicate that under low power, the maximum error for DST dataset is 4.75%, while for UDDS dataset, it is only 3%, demonstrating its capability to accurately estimate battery SOC. In summary, the new approach provides a novel and effective pathway for battery management under low power conditions, holding significant theoretical and practical implications for the advancement of battery technology.

Influenced by meteorology, production, holiday factors and so on, user loads fluctuate randomly. General linear regression methods are difficult to describe the nonlinear trends of load changes. Machine learning algorithms can be used to fully explore the correlation between data before and after the sequence. In order to improve the predictive performance of the model, a user load prediction method combining micro meteorological monitoring and deep learning algorithms is proposed. Firstly, the mRMR method is used to select variables from the input meteorological and load historical data, reducing the input dimension, thereby reducing the complexity of the model and improving the efficiency of the prediction algorithm. Then, the dimensionality reduced variable historical data is input into LSTM to establish an mRMR-LSTM user load prediction model. The load forecasting experiment was conducted using historical data of users from six industries in the city. The results showed that, while ensuring the efficient operation of the model, the model has a good predictive effect on user loads in most industries.
