аміаку полягає у пошуку оптимальнихпараметрів і умов роботи для досягнення певних цілей або максимальної продуктивності процесу при обмежених ресурсах та обставинах.
В даній роботі запропоновано використання дискретної системи керування з моделлю апаратом повітряного охолодження (АПО) й проведено аналіз економічної доцільності використання вищезгаданої системи.
В результаті такого аналізу встановлено, чи підходять наближені розв'язки для використання у практичних застосуваннях або чи потрібно використовувати більш точні методи розв'язування.
По-перше було обрано оптимальний ступень дискретизації (0,5℃), який, з одного боку забезпечував якомога більш точне вираховування дрібних змін величини, а з іншого – не призводив до збільшення кількості можливих станів або комбінацій, що значно підвищує обчислювальну складність задачі, особливо при роботі зі складними математичними моделями.
По друге, доведено доцільність та ефективність використання дискретної системи керування з моделлю вузлом охолодження та конденсації при врахуванні забруднень як збурюючи координату в автоматизацій ній схемі апарата повітряного охолодження. Це забезпечує більш ефективне та точне керування процесом за рахунок зміни режимів роботи вентиляторів чи інших систем охолодження в залежності від рівня забруднення. При збільшенні рівня забруднення система автоматично підвищує оберти вентиляторів або змінює параметри охолодження для компенсації зменшення ефективності теплопередачі.
По-третє, проведено розрахунки економічної доцільності використання дискретної системи .
Для розрахунків економічної доцільності були використані наступні допущення:

Потужність одного вентилятора N = 100 кВт (згідно регламенту).
Вартість електроенергії С 4,06 грн за 1 кВт (середнє значення в Україні для підприємств).
Тривалість роботи агрегату в теплий період року, Н - 5000 годин/рік (зазначено у тексті).
Кількість можливих комбінацій вентиляторів, К - 256 (як обговорювалося раніше).

Максимальна економія, згідно цим розрахункам, тановить 2,7млн грн..
Enterprise innovation and investment activities risks systematisation in the context of post-conflict transformations
Authors: Ivchenko Yu.A. 
Published: October 2023

The article analyses types of risks that are typical for domestic business entities. It improves classification of innovation and investment risks of an enterprise by means of expansion of classification features. Domestic enterprises are constantly solving the problem of identifying, assessing and managing business risks, which is even more important in the context of post-conflict transformations. Therefore, the problem of identifying and systematising the risks of innovation and investment activities of enterprises in the context of post-conflict transformations is relevant and requires scientific substantiation. The risks of innovation and investment activities should be considered not in the historical dimension, but in the context of their minimisation in the future. When implementing innovation and investment activities, which are unpredictable in themselves, it is simply not possible to consider risk "as a result", because innovations have no analogues and it is impossible to extrapolate the experience of other projects. iIf risk is the possibility of deviation from a certain value, then such a possibility can be assessed using relative scores, the deviation can be determined by direction (positive, negative, zero), and the risk itself can be characterised by type.
Based on the results of a qualitative risk analysis, an enterprise should assess the risks and determine a set of organisational decisions to manage them (types of management decisions to minimise their possible impact). The allocation of the proposed feature "Risks of post-conflict transformations" allows to take into account new types of risks that arise in the socio-political and economic environment in the new economic conditions and relate to: the crisis state of the economy, demographic changes in the job market, social attitudes, the state and quality of the information space, infrastructure support, the level of innovation and investment, energy, transport, consulting, engineering and other types of activities, etc. Possible methods for assessing various types of risks of innovation and investment activities of enterprises are outlined. In general, the author's proposals can be used to formalise approaches to assessment of innovation and investment risks.
Potret perbandingan kebijakan harga pangan dengan realita harga beras, gula dan kedelai di tahun pertama pandemi Covid-19, Indonesia
Authors: Ivan's Eny , Sari Novia Ambar 
Published: October 2023

Penyebab kelangkaan komoditi pertanian adalah karena kebijakan lockdown dan PSBB di awal pandemi, serta perilaku punic buying dari konsumen. Tujuan penelitian ini adalah membandingkan antara kebijakan harga komoditi beras, gula dan kedelai dengan realita harga yang terjadi di tahun pertama pandemi Covid-19. Data sekunder yang digunakan dalam penelitian ini merupakan data harian dan bulanan harga komoditas dari SP2KP Kementerian Perdagangan dan BPS. Data tersebut dianalisis menggunakan grafik dan dibandingkan dengan kebijakan harga yang berlaku saat ini pada tiga komoditas tersebut. Hasil kajian menunjukkan bahwa kebijakan harga untuk komoditi beras, gula dan kedelai di tahun pertama pandemi Covid-19 belum menunjukkan keberpihakan kepada petani. Tingginya harga beras di tingkat ecer tidak berbanding lurus dengan kenaikan harga gabah di tingkat produsen. Harga gula yang fluktuatif dikarenakan periode impor gula bersamaan dengan periode panen tebu. Penghapusan tarif impor kedelai menjadi 0% menjadikan petani domestik bersaing secara face to face di pasar global.
The cause of the scarcity of agricultural commodities is due to the lockdown policy and PSBB (large-scale social restrictions) at the beginning of the pandemic Covid-19 and the punic buying behavior from consumers. The research objective was to compare the commodity price policies for rice, sugar, and soybeans with the price realities that occurred in the first year of the Covid-19 pandemic. Secondary data used in this study are daily and monthly data on commodity prices from SP2KP of the Ministry of Trade and BPS. The data is analyzed using charts and compared with the prevailing price policies for these three commodities. The study results show that the price policy for rice, sugar, and soybean commodities in the first year of the Covid-19 pandemic has not shown partiality to farmers. The high price of rice at the retail level is not directly proportional to the increase in grain prices at the producer level. Sugar prices fluctuate because the sugar import period coincides with the sugar cane harvest period. The elimination of import tariffs to 0% allows domestic farmers to compete directly in the global market.

IntroductionThe midgut epithelium functions as tissue for nutrient uptake as well as physical barrier against pathogens. Additionally, it responds to pathogen contact by production and release of various factors including antimicrobial peptides, similar to the systemic innate immune response. However, if such a response is restricted to a local stimulus or if it appears in response to a systemic infection, too is a rather underexplored topic in insect immunity. We addressed the role of the midgut and the role of systemic immune tissues in the defense against gut-borne and systemic infections, respectively.MethodsManduca sexta larvae were challenged with DAP-type peptidoglycan bacteria – Bacillus thuringiensis for local gut infection and Escherichia coli for systemic stimulation. We compared the immune response to both infection models by measuring mRNA levels of four selected immunity-related genes in midgut, fat body, hematopoietic organs (HOs), and hemocytes, and determined hemolymph antimicrobial activity. Hemocytes and HOs were tested for presence and distribution of lysozyme mRNA and protein.ResultsThe midgut and circulating hemocytes exhibited a significantly increased level of lysozyme mRNA in response to gut infection but did not significantly alter expression in response to a systemic infection. Conversely, fat body and HOs responded to both infection models by altered mRNA levels of at least one gene monitored. Most, but not all hemocytes and HO cells contain lysozyme mRNA and protein.DiscussionThese data suggest that the gut recruits immune-related tissues in response to gut infection whereas systemic infections do not induce a response in the midgut. The experimental approach implies a skewed cross-talk: An intestinal infection triggers immune activity in systemic immune organs, while a systemic infection does not elicit any or only a restricted immune response in the midgut. The HOs, which form and release hemocytes in larval M. sexta, i) synthesize lysozyme, and ii) respond to immune challenges by increased immune gene expression. These findings strongly suggest that they not only provide phagocytes for the cellular immune response but also synthesize humoral immune components.
Involving trained community health mediators in COVID-19 prevention measures. A process evaluation from Bremen, Germany

Published: October 2023

ObjectiveThe objective was to assess the feasibility of incorporating trained community health mediators in COVID-19 prevention in a multicultural and disadvantaged setting in Bremen, Germany. Specifically, we aimed to develop and implement measures corresponding to the needs of the residents and to analyse the role of digital communication tools and sustainability factors of the health mediator approach.MethodsA comprehensive process evaluation using 41 qualitative interviews with residents, mediator short surveys and group discussions, work documentation sheets, and a stakeholder workshop was carried out.ResultsUncertainties due to changing regulations, a lack of trust and fear of potential side effects were major themes identified in the needs assessment. The eight mediators documented more than 1,600 contacts. Digital communication via Facebook was a useful tool, but personal contacts remained crucial for communicating with residents. The participatory approach, multilingualism and the flexibility to react to dynamic situations were identified as relevant factors for the success and sustainability of the health mediator approach.ConclusionMultilingual health mediators can facilitate contact with and dissemination of health information to different communities and also can play an important role in pandemic preparedness.
