Objective: aims to estimate emissions of the main atmospheric pollutants from vehicular sources in the state of Pará, to continue the environmental agenda of monitoring air quality.

Theoretical Framework: The growing global concern about air quality in urban areas is driven by the environmental and public health impacts caused by air pollution. The concentration of pollutants from vehicle sources represents one of the main challenges, especially in densely populated regions such as the capital and other major cities in the state of Pará, where the automotive fleet has increased significantly.

Method: The methodology used combined "bottom-up" and "top-down" methods to calculate emissions of carbon monoxide (CO), nitrogen oxides (NO) and total hydrocarbons (HC) for different vehicle categories and fuel types. Data on licensed vehicle fleets and fuel consumption obtained from DETRAN-PA and ANP were used.

Results and Discussion: The results revealed that gasoline-powered vehicles are responsible for the majority of CO and HC emissions, while diesel vehicles emit the largest amounts of NO into the atmosphere. Motorcycles were identified as the largest source of emissions due to their larger number in the circulating fleet. Our results also highlight the importance of assessing and monitoring vehicle emissions to develop effective air pollution control strategies.

Research Implications: The information obtained in this study is unprecedented for the study area, and can therefore support the formulation of environmental policies aimed at reducing emissions of atmospheric pollutants in the state of Pará, thus promoting an improvement in air quality and public health.

Originality/Value: This paper makes an unprecedented contribution to national and international literature on environmental pollution in large urban centers. On the eve of the largest climate and environment conference on the planet (COP30) to be held in Pará, Amazonas, this research joins efforts in relation to the monitoring, forecasting and mitigation of air pollution, considered one of the main environmental problems of today.

The growth of oil palm plants is greatly influenced by the availability of nutrients in the soil. The availability of nutrients is determined by the physical, chemical and biological properties of the soil. Marginal soils such as Ultisol have very low levels of nutrient availability. This is caused by intensive weathering processes. Therefore, it is necessary to improve soil fertility. One effort that can be made to improve the fertility of Ultisol soil so that oil palms can grow well is by adding natural fertilizer. Natural fertilizer can come from the use of plant or animal remains. One of them is the use of cow blood waste, this waste has not been widely used as a source of natural fertilizer.
One type of mineral soil that is widely used as a medium for growing seeds is ultisol soil. This happens because this type of soil is spread quite widely in Indonesia. The weakness of Ultisol soil as a growing medium is that this soil generally reacts very acidly. Therefore, to increase the growth of plant seeds, a good growing medium is needed for plants. To create a good growing medium, fertilizer is needed that contains alkaline reacting substances such as Potassium (K). One type of fertilizer that contains potassium is KCl fertilizer (Nugroho, 2000).
The aim of the research is to determine the effect of liquid organic fertilizer from cow's blood and gamal leaves on the growth of oil palm seedlings. The research was carried out for 20 weeks (5 months) starting from February – June 2024. The research was carried out at the Agrotechnology Experimental Garden at Widya Gama Mahakam University, Samarinda.
This research was organized in a Randomized Group Design (RAK) with Factorial analysis of 2 factors with 3 replications and obtained 48 polybags as follows: Cow Blood Liquid Organic Fertilizer consisting of 4 levels, namely: D0 (No Control Treatment), D1 (80 mL /L water), D2 (100 mL/L water) D3 (120 mL/L water). The second factor is KCl (K) fertilizer which consists of 3 levels, namely: K0 (0 g/tan), K1 (0.15 g/tan) and K2 (0.30 g/tan). Data were analyzed using analysis of variance based on the F test 5% and 1%. If it has a real effect, continue with the 5% BNT test.

Sortir du nihilisme : Nietzsche, Mill et l’individualité comme clé de transformation morale et civilisationnelle
Authors: Dejardin Camille 
Published: October 2024

Nietzsche’s criticism of the masses could have looked hackneyed at the end of the XIXth century, had it not the originality of moving onto psychological and biological levels what others previously elaborated only at a social scale: a "herd instinct" explaining both the lack of social cohesion and the loss of possible individual affirmation in democratic and egalitarian ages. As he sees the utilitarian promotion of happiness and empathy as part of the problem, he fiercely condemns John Stewart Mill’s philosophy – as he understands it. Our point is to throw into relief that Mill’s theory of individuality is but closer to Nietzsche’s views for regenerating life against the spreading of democratic "nihilism". Our cross-reading of Mill and Nietzsche therefore aims at offering a reassessment of their antagonism and at highlighting ways of overcoming "nihilism" via culture and cultivation of the "character" and the individual surpassing of oneself.

В ходе исследования был обоснован выбор оптимальной температуры нефти при воздействии на неё ультразвуком, приведена теоретическая схема промыслового реактора для ультразвукового воздействия на нефть, а также доказана эффективность его применения. Были рассмотрены различные методы борьбы с проблемами, вызванными тяжелыми нефтями, такие как применение специальных химических реагентов, физические методы, механические и тепловые методы. Каждый метод был описан подробно. В результате исследования были получены следующие выводы: влияние акустических полей на нефть не до конца изучено и требует дальнейших исследований, однако уже на данный момент виден потенциал обработки нефти ультразвуком, связанный с процессами кавитации, которые происходят в нефти при ультразвуковом воздействии и способствуют улучшению как физических, так и химических свойств нефти.
The purpose of this work is to study the effect of an acoustic field on a sample of heavy oil. In the course of the study, the choice of the optimal oil temperature when exposed to ultrasound was justified, a theoretical scheme of a field reactor for ultrasonic exposure to oil was given, and the effectiveness of its application was proved. Various methods of dealing with problems caused by heavy oils were considered, such as the use of special chemical reagents, physical methods, mechanical and thermal methods. Each method has been described in detail. As a result of the study, the following conclusions were obtained: the effect of acoustic fields on oil has not been fully studied and requires further research, however, at the moment the potential of oil treatment with ultrasound is already visible, associated with cavitation processes that occur in oil under ultrasonic exposure and contribute to the improvement of both physical and chemical properties of oil.

Published: October 2024

В связи с увеличением средней продолжительности жизни появилась необходимость пересмотреть ряд понятий и терминов, характеризующих демографические и социальные показатели, возрастные этапы и возрастную периодизацию. Предлагается ввести в научный оборот термин «Возраст дожития до 120» (ВД120). Термин отражает число лет, которые может дожить до условно принятой цифры в 120 лет. Новый термин отличается от «возраста дожития», существующего официально и используемый в органах социальной защиты и пенсионного страхования. ВД120 может служить альтернативой для адекватной оценки последующих демографических и социальных изменений
Due to the increase in average life expectancy, it has become necessary to revise a number of concepts and terms characterizing demographic and social indicators, age stages and periods of human growth. It is proposed to introduce the term "Age of survival to 120" (VD120) into scientific use. The term reflects the number of years that a person can live up to the conventionally accepted figure of 120 years. The new term differs from the "age of survival" that exists in the bowels of the banking system of the state, social protection agencies and pension insurance. VD120 can serve as an alternative for an adequate assessment of subsequent demographic and social changes

Пиковая частота тета ритма в условиях интеллектуальной нагрузки. Работа посвящена изучению характеристик пиковой частоты тета ритма в условиях интеллектуальной нагрузки эмоционально нейтрального содержания, а именно: испытуемые должны были мысленно представить состояние ожидания инструкции. Работа была проведена на 33 испытуемых в возрасте 18-22 лет. Последовательность операций была следующей. 1) запись фона – 2 мин, 2) мысленное представление состояния ожидания инструкции 30 секунд. ЭЭГ регистрировали по международной схеме 10-20 % от 16 отведений: Fp1, Fp2, F3, F4, F7, F8, СЗ, С4, РЗ, Р4, ТЗ, Т4, Т5, Т6, О1, О2. Обработка данных состояла в расчете спектральной мощности ЭЭГ методом дискретного преобразования Фурье в полосе тета ритма в исследуемых отрезках. Оценки спектральной мощности были получены усреднением выборочных спектров по соседним частотам и по непересекающимся эпохам анализа 4 секунды. В качестве оценки интенсивности колебаний ЭЭГ в данной частотной полосе была избран параметр «спектральная мощность», который соответствует средней мощности исходного ЭЭГ- сигнала после фильтрации в указанной частотной полосе
The work is devoted to studying the characteristics of the peak frequency of theta rhythm under intellectual load of emotionally neutral content, namely: the subjects had to mentally imagine the state of waiting for an instruction. The work was carried out on 33 subjects aged 18-22 years. The sequence of operations was as follows. 1) background recording - 2 min, 2) mental representation of the state of waiting for an instruction 30 seconds. EEG was recorded according to the international scheme 10-20% of 16 leads: Fp1, Fp2, F3, F4, F7, F8, C3, C4, P3, P4, T3, T4, T5, T6, O1, O2. Data processing consisted of calculating the spectral power of the EEG using the discrete Fourier transform method in the theta rhythm band in the studied segments. The spectral power estimates were obtained by averaging the sample spectra over adjacent frequencies and over non-overlapping 4-second analysis epochs. The "spectral power" parameter was chosen as an estimate of the intensity of EEG oscillations in a given frequency band, which corresponds to the average power of the original EEG signal after filtering in the specified frequency band
