Wizytówka Messnera
Authors: Krupa Maciej 
Published: July 2023

Reinhold Messner has said frequently that in the fi rst period of his activity in the mountains his climbing partners were often local farmers from the Valley of Funes in South Tyrol. The entire region of the Alps is inhabited by traditional peasant communities. Despite civilisational transformations we can still encounter there farms and their residents who like to climb the mountains for pleasure. Yet the Golden Age of mountaineering in the mid-19th century was dominated by an elite of British climbers with aristocratic, scholarly and cultural backgrounds. They were guided by highlanders from the foot of the Alps.
However, as early as in the 1950s and 1960s British mountaineering became the domain of the working class as well, thanks to Don Whillans. Among the modern climbers from Western Europe and the United States there are many workers, manual labourers, people with no higher education. On the other hand in Poland mountaineering was from the beginning an elite activity and has remained so to this day. Climbing has attracted and still attracts engineers, academics, creative professionals, doctors and artists. Among Polish climbers there have not been and there are no farmers, workers, uneducated people or those doing manual labour. The exception is mountain guides and rescuers, but they climb professionally, so to speak, and not con amore.
Why is that? Why do Polish highlanders — with few exceptions — not climb? Why has this been the case for nearly two hundred years? And what is surprising about Reinhold Messner’s visiting card which he gave Jerzy Kukuczka?
Improvement of the strength calculation of the tube plate of the shell-tube heat exchanger
Authors: Andreiev Igor 
Published: July 2023

The purpose of the article is to improve the strength calculation of the tube plate of the shell-and-tube heat exchanger, which is regulated by the interstate standard in force in Ukraine.
On the basis of standard tables, dot plots of the change in coefficients were constructed and analyzed, which take into account the supporting effect of pipes Ф1, Ф2, Ф3 depending on the dimensionless parameter of the board-pipe system ω and the dependence of the stiffness coefficient of the perforated board on the coefficient of pressure effect on the tube plate from the side of the tube space ηТ. It is proposed to approximate these dependencies with simple mathematical equations.
As a result, it was proposed to use the cubic regression Ф1 = 0,0422ω3 + 0,2305ω2 – 0,2367ω + 2,0179 to describe the dependence of Ф1 = f1(ω) in the range of ω from 0 to 3 and when changing ω from 3 to 11, apply quadratic regression Ф1 = – 0,0286ω2 + 1,8012ω – 0,6171. The dependence of Ф2 = f2(ω) in the range of changing ω from 0 to 0,5 due to a slight change in the function can be described by the linear equation Ф2 = 0.04ω, when changing ω from 0,5 to 2 - by the cubic regression Ф2 = 0,0133ω3 + 0,48ω2 – 0,4033ω + 0,1, and when changing ω from 2 to 11 – by cubic regression Ф2 = 0,0046ω3 – 0,1129ω2 + 1,8692ω – 1,8821. The dependence Ф3 = f3(ω) in the range of ω change from 0 to 0,5 is described by the linear equation Ф3 = 0,38ω, when ω changes from 0,5 to 3 – by cubic regression Ф3 = – 0,2296ω3 + 1,3541ω2 – 0,4884ω + 0,1233, and when ω changes from 3 to 11 – cubic regression Ф3 = – 0,0054ω3 + 0,1060ω2 + 0,7576ω + 1,6129. The discrete tabular dependence of ψ0 on ηТ can be approximated by cubic regression ψ0 = – 0,3419ηТ3 + 1,8834ηТ2 – 0,6915ηТ + 0,1153.
The obtained formulas make it possible to abandon the use of standard tables and additional interpolation of intermediate values of the coefficients Ф1, Ф2, Ф3 and ψ0 when performing calculations, which in turn simplifies both the calculation itself and the development of appropriate computer programs.
The average value of the errors of the performed approximations is in the range from 0% to 2.05%, which indicates a high level of coincidence of the regression equations with the actual values.
The use of the proposed formulas for the dependences of the coefficients Ф1 = f1(ω), Ф2 = f2(ω), Ф3 = f3(ω) and ψ0 = f(ηТ) makes it possible to simplify the calculation of the tube plate of shell-and-tube heat exchangers for strength.

Iron oxide nanoparticles have been investigated due to their suitable characteristics for diverse applications in the fields of biomedicine, electronics, water/wastewater treatment and sensors. Maghemite, magnetite and hematite are the most widely studied iron oxide particles and have ferrimagnetic characteristics. When very small, however, these particles have superparamagnetic properties and are called superparamagnetic iron oxide nanoparticles (SPIONs). Several methods are used for the production of these particles, such as coprecipitation, thermal decomposition and microemulsion. However, the variables of the different types of synthesis must be assessed to achieve greater control over the particles produced. In some studies, it is possible to compare the influence of variations in the factors for production with each of these methods. Thus, researchers use different adaptations of synthesis based on each objective and type of application. With coprecipitation, it is possible to obtain smaller, more uniform particles with adjustments in temperature, pH and the types of reagents used in the process. With thermal decomposition, greater control is needed over time, temperature as well as the proportion of surfactants and organic and aqueous phases in order to produce smaller particles and a narrower size distribution. With the microemulsion process, the control of the confinement of the micelles formed during synthesis through the proportions of surfactant and oil makes the final particles smaller and less dispersed. These nanoparticles can be used as additives for the creation of new materials, such as magnetic bacterial cellulose, which has different innovative applications. Composites that have SPIONs, which are produced with greater rigour with regards to size and distribution, have superparamagnetic properties and can be used in medical applications, whereas materials containing larger particles have ferromagnetic applications. To arrive at a particular particle with specific characteristics, researchers must be attentive to both the mechanism selected and the production variables to ensure greater quality and control of the materials produced.

Data analysis techniques used are data reduction, data exposure, and drawing conclusions. To check the validity of the data using the triangulation method.
Based on the results of research in the field, it is known that the implementation of e-commerce at Bebaya Mart is in accordance with the four components needed in online transactions. A review of Islamic business ethics on the application or implementation of e-commerce at Bebaya Mart shows that the ethical values of Islamic business in tauhid are mostly implemented because two out of four sellers still make a profit solely on the grounds of survival alone. However, products are sold halal, sellers never commit fraudulent acts to consumers. Bebaya Mart admins do not get any profit from sellers and buyers. The equilibrium has implemented it starting in terms of price, product quality, until sellers treat consumers equally. Free will has implemented it, namely the admin of Bebaya Mart pays attention to the rights of sellers and buyers, sellers give consumer freedom rights. The responsibility is mostly implemented because there is no rating system in the Bebaya Mart application. The seller is responsible for all the information he provides such as product quality to delivery of goods. The seller is also responsible if the buyer or consumer submits a compound. And truth, honesty has not implemented the value of truth, honesty because there are several image posts displayed are still being edited, there is one seller who has not displayed product specifications, and the Bebaya Mart application has not socialized the scales or dosages.

The increasing population makes the volume of waste production also increase and varies. The amount of waste generated will have a negative impact on the environment and the economy. Therefore, the waste must be managed properly so that is becomes useful goods and has economic value. An organization that plays a role in waste management is a sharia waste bank, but in reality someone’s interest in becoming a waste bank customer does not just appear. One of them is influenced by motivation, the more motivated a person is, the greather his interest in something. Next is the quality or service, the better the service provided, the more interested someone is in something. This type of research is quantitative with a causal associative approach. The population this study were active students of UINSI Samarinda from 2018 to 2022. The sampling technique used was simple random sampling. Data collection techniques using questionnaires and documentation. The data analysis techniques are ordinal to interval data transformation (MSI), instrument test, classical assumption test, multiple linear regression analysis, coefficient of determination and hypothesis testing. Based on the results of the results of the t test it is known that motivation (X1) does not affect the interest, while the quality of service (X2) affects the interest. Simultaneously, motivation (X1) and service quality (X2) affect the interest.

The Constitutional Court Decision and Islamic Philanthropy Movements: Analysis of Zakat Organizations Legality in Samarinda
Authors: Iswanto Bambang , Hadinatha Miftah Faried 
Published: July 2023

As the capital of East Kalimantan province, Samarinda city government has adequate access to ensure the Legality of zakat management organizations in its jurisdiction. However, many community-based zakat agencies still carry out their activities without state license. Otherwise, the Constitutional Court Decision Number 86/ PUU-X/2012 obliges these zakat agencies to get the Ministry of Religious Affairs permit based on the National Amil Zakat Agency (BAZNAS) recommendation, in this case, the BAZNAS of Samarinda. This article focuses first on the legal implication of the Court’s decision which confirms the constitutionality of the zakat agencies' licensing requirement in Indonesian Zakat Law. Second, it probes the Samarinda community-based zakat agencies' stance on unlicensed activities and factors affecting their compliance with the Court's decision. Using socio-legal method, this article finds that the Court has established a norm that every zakat management organization must obtain the state's license as long as they operate within the jurisdiction of BAZNAS. Hence, it is considered illegal when community-based zakat agencies in Samarinda manage zakat unlicensed because every corner of the city is arguably within reach of BAZNAS Samarinda operation. Nevertheless, the Court's ruling is not observed by the society in Samarinda because they build their own social construction in implementing the Islamic teaching of zakat. Their stance is mainly influenced by religious motives instead of legal compliance, as well as the hereditary obedience to religious figures. Although many zakat agencies are not licensed, the society always feels benefited and facilitated by their work of collecting and distributing zakat in their region.
