The Impact

The impact of competition in the industry has driven people to improve the effectiveness of production process. One of the main factors supporting that effectiveness is the good planning of both the need and the number of machines. The aim of this study is to estimate the machining times to determine the number of machines to manufacture 100/day of the nut releaser tool for car wheel. The result shows that the need of the number of machines to manufacture each component of the nut releaser tool for car wheel are 7 units of power hacksaw, 27 units of lathe machine, 8 units of drilling machine, 12 units of milling machine, 2 units of EDM machine and 25 units of bench work.

Material Requirements

Shaping and marketing a product in tablet form is an easy and economical alternative to product shaping. Products in tablet form now cover almost all fields, so that the demand for tablet tooling of various sizes and variations continues to increase. As an effort to support the effectiveness and proper industrial planning, it is necessary to carry out an analysis of the machine and material requirements to produce tablet tooling which is the aim of this study. To achieve these objectives, the methods used in this study include product design, operation plan analysis, and calculation of material requirements and number of machines. The result shows that the number of machine requirements to manufacture the die and punch of tablet tooling with the demand of 200 unit/day are two units of power hacksaw, five units of lathe machine, and a unit of milling machine. On the other hand, the material requirements needed in one day are 22.24 m (Ø45 mm x 5 bars) and 12.79 m (Ø18 mm x 3 bars).

The Impact

To overcome pandemics, such as COVID-19, vaccines are urgently needed at very high volumes. Here we assess the techno-economic feasibility of producing RNA vaccines for the demand associated with a global vaccination campaign. Production process performance is assessed for three messenger RNA (mRNA) and one self-amplifying RNA (saRNA) vaccines, all currently under clinical development, as well as for a hypothetical next-generation saRNA vaccine. The impact of key process design and operation uncertainties on the performance of the production process was assessed. The RNA vaccine drug substance (DS) production rates, volumes and costs are mostly impacted by the RNA amount per vaccine dose and to a lesser extent by the scale and titre in the production process. The resources, production scale and speed required to meet global demand vary substantially in function of the RNA amount per dose. For lower dose saRNA vaccines, global demand can be met using a production process at a scale of below 10 L bioreactor working volume. Consequently, these small-scale processes require a low amount of resources to set up and operate. RNA DS production can be faster than fill-to-finish into multidose vials; hence the latter may constitute a bottleneck.

Production of components, necessary for the construction of the machine resp. or device is a demanding manufacturing process. One of the possibilities of increasing efficiency and production quality is the introduction of unconventional technologies to the production process. Knowing the dependence of the impact of non-conventional technologies on the mechanical properties of products and their subsequent verification is an important aspect when designing and manufacturing them. The article deals with the impact of used unconventional technology, that means laser, plasma and water jet on the roughness of a cutting edge and microhardness of material S 355 J2 G3.

Natural materials and processes represent the global substance reflecting and determining its formation and existence as a whole and in all its components. Revealing the reasons for their formation and manifestation is crucial. The paper highlights the two main factors: «influences» and «gradients». Influences are interpreted as the impact of some substances and events on other similar parameters, and gradients are vector changes and differences in systems composition, structure, properties, states, energy and thermodynamic parameters. To provide an insight into the role and significance of the above factors and reasons, an attempt was made to consider their potential manifestation throughout the general world history within the existing knowledge about it.

The purpose of the study is to influence land resources during mining operations, and the main stages of land reclamation during mining on the example of the Tyradinsky gold Deposit, the "Zolotaya Tyrada" quarry, located in the Yenisei region of the Krasnoyarsk territory. The main factors of impact on land resources in the process of mining the field are considered; the analysis of measures to reduce the negative impact on land resources in the process of mining the field is carried out. The actual height and area of overburden dump not to exceed project, the reconfiguration of dumps allowed us to reduce the impact of mining on the environment, to avoid placing parts of the dumps in the water protection zone of the river Terada, thus there is no need of land allocation to forests of the first group and reduced the amount of removed topsoil. During the reclamation, potentially fertile soils (loam) taken from the quarry were used. There will be no deterioration in the impact on land resources during the liquidation process, due to the short duration of the work and within the existing land allotment.

The factors influencing the intensification of the migration process have been considered since the appearance of the first migration theories. These factors determine both the potential migration opportunities and the actual conditions for the implementation of the migration process. Among the main factors that determine the intensity of the migration process, basic are the factors formed by the labor market (economic factors). Despite a number of migration theories that consider other factors, such as the demand structure, psychological and social factors, we determine the impact of precisely the economic factors (factors formed in the labor market) as the most significant. In today’s world, when determining the intensity and main directions of migration, the economic factors are taken into account by the majority of migrants. At the same time, indirect factors play an important role in the analysis of the migration process. Indirect factors, determining the basic conditions for the intensification of the migration process, form the potential for migration. Potential migration opportunities form an environment that determines the potential number of migrants. Indirect factors include not only the parameters of the development of the national economy as a whole, but also the parameters of the development of individual regions or territories that form the migration attractiveness of these regions.

Abstract Tofu contains various substances that are very good when consumed to improve people’s nutrition. In addition, tofu also has good taste. The problem is that the tofu production process produces products and non-product outputs in the form of waste that is very dangerous if directly disposed of in the environment. The BOD5 content of tofu small and medium-sized enterprises (SMEs) in Sugihmanik Village ranged from 3,667-4,933 mg/L and COD 7,668-9,736 mg/L. At the same time, the TSS values ranged from 701-1,189 mg/L. The BOD5 value in the river water content is 367 mg/L. It greatly exceeds the set Threshold Value. This study aims to measure the environmental impact using Life Cycle Assessment (LCA). LCA can identify the impact of each activity based on the impact category to identify the processes that contribute significantly to damaging the environment. This study found that the cooking and frying process had the highest impact, where the climate change category was the largest. Wastewater treatment plants, biogas from the biodigester as a substitute for electricity for water pumps, rice husks, and corn cobs are expected to reduce environmental impacts.
