This paper presents a methodology that combines radar polarization selection and recognition techniques for navigating objects in atmospheric formations, with a special focus on unmanned surface vehicles (ASVs). The proposed technique utilizes the concept of an energy dissipation matrix to represent these objects as characteristic “shiny dots”. By strategically changing the polarization of the emitted and received electromagnetic waves, the resulting echo energy dissipation matrix is determined. This approach allows the formation of an intensity-based repository of atmospheric formations, which gives SRPC a complete set of tools to account for atmospheric conditions in radar identification of remote objects, including ASVs. The practical application of this technique extends to the improvement of a distinct class of shipborne radar systems optimized for ASVs and their specific navigation requirements. Ultimately, this technology bridges the gap between advanced radar technology and the emerging field of unmanned ground vehicles, providing safer and more proficient navigation in challenging weather conditions.

In this global competitive environment, with the recent advancement in information and communication technologies, the industries are adopting new strategies to sustain. Cloud manufacturing is a new technology that utilizes data analytics for better decision-making resulting in more productive, cost, and energy efficient operations. Increasing awareness towards a clean environment and optimum utilization of resources in manufacturing motivate us to study cloud manufacturing in the context of sustainability. Therefore, a significant number of social, environmental, and economic factors of cloud manufacturing are identified through literature review, and experts’ opinions and prioritization of these factors are obtained through the AHP and Fuzzy AHP methods. As per the final results obtained, “Efficient use of resources” is the most significant factor for the adoption of cloud manufacturing process and “Remote material monitoring” is the least significant factor amongst all the factors taken under consideration. The results are found to be consistent and accurate as per the value of consistency ratio. And the percentage obtained for social, environmental, and economic factors proves the cloud manufacturing process to be a sustainable manufacturing process.

Driven by national policies and international competitions, China’s winter sports and industry development will enter a new course. How to release the enormous potential skiing demand in China is significant to drive 300 million people to participate in winter sports and promote the development of China’s ice and snow industry, and defining the restrictive factors is a necessary prerequisite to realise the effective transformation of potential demand to actual growth power. Based on the in-depth information, this paper further analyses the influence of environmental factors on the development of winter sports. The research shows that the number of skiers about 20 times is the highest, up to 75.5 %, followed by the number of skiers about five times, up to 67.4 %. Then about ten times accounted for 48.6 %, and finally, about 15 times accounted for 37.6 %. This frequency can fully satisfy skiing enthusiasts to enjoy leisure activities, experience modern life fashion, use skiing to increase social opportunities, delight body and mind, and improve health. Based on the in-depth information, this paper reveals the shortcomings and existing environmental factors of China’s winter sports development. It provides a reference for the rational utilisation and development of ice and snow resources and the scientific and practical development of China’s winter sports.

Environmental factors in workspaces affect employee productivity and satisfaction, particularly in call centres. One of the most challenging issues in contemporary offices is overcoming the problems of concentration on work, despite adverse effects such as insufficient lighting, inappropriate acoustics, or inadequate ventilation. The challenges increase in open-plan solutions. This paper presents a case study from Turkey that elaborates on strategies to improve environmental performance in call centres. It is inspired by a questionnaire conducted among employees of a call centre, identifying existing design lacks. Based on the results, acoustic quality calculations of the physical workspace follow, and initial computing outcomes reveal that the conditions do not meet the standards for call centres. The authors propose strategies to improve acoustic performance in the workspace and apply them to a virtual model. Results reveal that the proposed solutions allow for meeting the standards. Based on the findings, the authors suggest several other strategies for improving the physical environmental quality of the place, thus forming a guideline for the architectural design of call centres. The study derives information from a specific case and context to propose universally applicable solutions. It fills a gap in the literature as it exemplifies the characteristics of call centres in Turkey, which have not been studied before.

This paper presents a concept for shielding the MSBS (Modular Firearms System) Grot rifle upper receiver against foreign objects. The concept guidelines involve feedback from Grot operators concerning the regular operation of the rifle plus an extensive analysis of desktop patent research into foreign debris shields (or dust shields) for protection of the upper receiver interior in firearms. The completed patent desktop research included solutions used with automatic, semi-automatic and non-automatic firearms. The research work drove the formulation of the requirements for an upper receiver dust shield for the 5.56 mm calibre MSBS Grot rifle as part of the ongoing improvement process. This paper presents three concepts of the carrier charging handle assembly dust shield (for the protection of the upper receiver against foreign objects) for the MSBS-5.56 rifle system. The concepts described vary in terms of the level of structural complexity of the dust shield, and the extent of the modifications required to the upper receiver of the rifle. With test units of the upper receiver dust shield manufactured and comparative tests completed on the three concepts, the version selected should be the one which improves the protection of the rifle internals from foreign objects found in the local environment, including sand, clay, silt, and mud, the latter being an aqueous suspension of these particles.

We investigated the response mechanisms of plant functional traits to environmental factors at the community level in order to elucidate the adaptive and survival strategies of plants in different environmental gradients. 184 vegetation sampling plots were laid by stratified random sampling in the Saihanba region of Hebei, China. Three functional traits (leaf nitrogen content, LNC; specific leaf area, SLA; leaf dry matter content, LDMC) were measured and the community-level weighted means of the trait values were calculated by the species coverage values. Climate and terrain data were generated from the climate model ClimateAP and using ArcGIS. Finally, eight environmental factors, including climate, topographical, and soil factor, were recorded and the association with functional traits was analysed using a generalized additive model. Model testing indicated a good predictability for the SLA and LDMC while a relatively poor predictability was seen with LNC. Environmental factors that significantly impacted SLA included elevation, degree-days above 0°C, mean annual precipitation and total soil nitrogen content. In contrast, LDMC was significantly influenced by elevation, total soil nitrogen and phosphorous content while LNC was affected by elevation and degree-days above 0°C. High values of SLA and LNC were found in areas at lower elevations. The distribution of high LDMC values indicated that plant leaves have a relatively high tolerance and resistance to stress, which was better for plant to grow in the adverse environment. At the community level, clarifying plant functional traits distribution and their changes with environmental gradients is useful for the potential vegetation restoration.

Çardak Lagoon is one of the most important marine environments in the Turkish Strait system, which is home to a variety of organisms. The lagoon is currently under stress and faces the risk of heavy pollution. For this reason, the present state of the lagoon was monitored in this study. During sampling from October 2018 to June 2019, the levels of indicator microorganisms fluctuated up to 4.04 Log10 cfu 100 ml−1 and their presence was found to be higher in warmer seasons. The highest positive correlations were observed for total coliform levels with salinity and chemical oxygen demand, whereas the highest negative correlations were found between the levels of fecal coliforms, pH and temperature. E. coli and fecal streptococci showed moderate correlations with the environmental factors in all seasons. Although nitrite and nitrate (NO2 + NO3) were not significantly correlated with bacteria levels, they were present at elevated levels. Çardak Lagoon showed the lowest microbiological and chemical quality in the summer season, and this situation continued into the autumn season as a possible result of increased wastewater discharge and human activities. The lagoon should therefore be monitored regularly and precautions should be taken to prevent severe ecological deterioration.

The popularity of Floating Homes in Western Europe and North America is noticeable. The interest in these facilities in Poland is also constantly growing. The popularity of Floating Homes is due to climate change, rising land prices and population density in city centers. However, environmental factors play a significant role in their development. The publication presents the results of research on the impact of environmental factors on the development of Floating Homes in Poland. As part of the research, the most important environmental factors were identified and then, using the State of the Surroundings Scenarios (SSS) method, an initial scenario of their development was developed. The most probable scenario was developed, the purpose of which was to identify the most favorable factors - strengths and unfavorable factors - weaknesses responsible for the development opportunities of Floating Homes in Poland. Additionally, a surprise scenario was prepared, which indicated factors that may unexpectedly accelerate the development of Floating Homes in Poland or slow it down.

The Green Deal and the New Industrial Strategy for Europe recognize the access to raw materials and the security of supply from secondary and primary sources as essential for Europe’s transition to sustainability. It can be expected that with the development of the circular economy approach, the extraction of primary resources would be diminished, but it is emphasized that a circular economy may need a wider range of metals and other raw materials critical to the new environmentally friendly technology, especially in renewable energy and mobility. Therefore, the latest global initiatives and EU policies focus on ensuring resource efficiency in a holistic manner, from the extraction of raw materials to the re-use of the end products, which requires data transparency not only on material and waste flows, but also on financial and economic burdens including incentives and subsidies. In addition, for sectors with significant environmental impacts, the transparency of information on payments to central governments and local authorities can increase social acceptance and accountability and allow for further development. The paper analyzes regulations and initiatives supporting the disclosure of wider data than required in financial and corporate social responsibility reporting related to the implementation of a circular economy. As circular economy indicators take upstream resource flows into account, the transparency of environmental and economic data in the value chain is required, for example for the calculation of the environmental footprint. Moreover, transparency is important for mining companies’ stakeholders to increase social acceptance of mining activities and facilitate the transition to a circular economy.

Zielony Ład i Nowa Strategia Przemysłowa dla Europy uznają dostęp do surowców i bezpieczeństwo dostaw ze źródeł wtórnych i pierwotnych za kluczowe elementy przejścia Europy na zrównoważony rozwój. Można się spodziewać, że wraz z rozwojem idei gospodarki o obiegu zamkniętym wydobycie surowców pierwotnych zostanie zmniejszone. Podkreśla się jednocześnie, że gospodarka o obiegu zamkniętym może wymagać szerszego zakresu metali i innych surowców krytycznych dla nowej, przyjaznej dla środowiska technologii, zwłaszcza w dziedzinie energii odnawialnej i mobilności. Dlatego najnowsze globalne inicjatywy i polityki UE koncentrują się na zapewnieniu efektywnego gospodarowania zasobami w sposób holistyczny, od wydobycia surowców po ponowne wykorzystanie produktów końcowych. Wymaga to przejrzystości danych nie tylko dotyczących przepływów materiałów i odpadów, ale także obciążeń finansowych i ekonomicznych, w tym zachęt i dotacji. Ponadto w przypadku sektorów o znaczącym wpływie na środowisko, przejrzystość informacji o płatnościach na rzecz rządów centralnych i władz lokalnych może zwiększyć akceptację i odpowiedzialność społeczną oraz umożliwić dalszy rozwój. Artykuł analizuje regulacje i inicjatywy wspierające ujawnianie szerszych danych niż wymagane w raportach finansowych i społecznej odpowiedzialności biznesu, związanych z wdrażaniem gospodarki o obiegu zamkniętym. Ponieważ wskaźniki gospodarki o obiegu zamkniętym uwzględniają przepływy zasobów, wymagana jest przejrzystość danych środowiskowych i ekonomicznych w łańcuchu wartości, na przykład do obliczania śladu środowiskowego. Ponadto przejrzystość jest ważna dla interesariuszy przedsiębiorstw górniczych, aby zwiększyć społeczną akceptację działalności górniczej i ułatwić przejście na gospodarkę o obiegu zamkniętym.

The methane (CH4) fluxes in grasslands are sensitive to changes in precipitation and soil nitrogen concentrations, which was poorly understood, especially on the Tibetan Plateau. Therefore, an experiment was conducted from May 2012 to October 2013, by using the static chamber technique and gas chromatography method. We set up five treatments: an increased 2 g m-2 NH4NO3 treatment (2gN); an increased 4 g m-2 NH4NO3 treatment (4gN); and treatment with precipitation increased by 20% (Pre), and added 2 g m-2 NH4NO3 and precipitation (20%) treatment (N+Pre), and a control treatment (CK). The five treatments showed decreasing CH4 uptake rates in the following order: CK (71.66 ± 6.6 µg m-2 h-1) > N+Pre (58.57 ± 3.7 µg m-2 h-1) > Pre (52.66 ± 2.3 µg m-2 h-1) > 2gN (47.63 ± 3.1 µg m-2 h-1) > 4gN (39.12 ± 3.3 µg m-2 h-1). The 2gN and 4gN treatment resulted in 33.5% and 45.4% lower CH4 uptake than the CK treatment, respectively. The path analysis indicated that the above-ground biomass and litter fall were the most important factor promoting and limiting the CH4 uptake rate of alpine meadow, respectively.

We studied the influence of abiotic environmental factors on the seasonal population dynamics' of Acartia spp., Temora longicornis and Pseudocalanus sp. in the southern Baltic Sea in the period of 2006-2007 and 2010-2012. Zooplankton samples were being collected monthly AT 6 stations located in the western part of the Gulf of Gdańsk with aWP2 net (100 μm mesh sizes) and then analyzed according to the HELCOM guidelines. Although the sampling stations did not significantly differ from each other in the terms of variability of abiotic environmental factors, the biomass of copepods developmental stages differed between them, apart from the shallow stations in both, Gulf of Gdańsk and in its inner part — Puck Bay. According to redundancy analysis, 26.1% of the total variability observed in the biomass of the copepod species has been explained by water temperature, salinity, air temperature, cloudiness, wind speed and direction and station's depth, with the first variable having the greatest power, alone explaining 13.7%. ANOSIM revealed that sampling stations in the Gulf of Gdańsk were significantly different from one another in terms of copepods' biomasses. Generalized Additive Models fitted for water temperature and salinity were significant for all ontogenetic stages of Acartia spp. and Temora longicornis and for the majority of stages of Pseudocalanus sp. (apart from the C1 for both and the males for salinity).

In order to prepare a coal company for the development of future events, it is important to predict how can evolve the key environmental factors. This article presents the most important factors influencing the hard coal demand in Poland. They have been used as explanatory variables during the creation of a mathematical model of coal sales. In order to build the coal sales forecast, the authors used the ARMAX model. Its validation was performed based on such accuracy measures as: RMSE, MAPE and Theil’s index. The conducted studies have allowed the statistically significant factors out of all factors taken into account to be identified. They also enabled the creation of the forecast of coal sales volume in Poland in the coming years. To maintain the predictability of the forecast, the mining company should continually control the macro environment. The proper demand forecast allows for the flexible and dynamic adjustment of production or stock levels to market changes. It also makes it possible to adapt the product range to the customer’s requirements and expectations, which, in turn, translates into increased sales, the release of funds, reduced operating costs and increased financial liquidity of the coal company. Creating a forecast is the first step in planning a hard coal mining strategy. Knowing the future needs, we are able to plan the necessary level of production factors in advance. The right strategy, tailored to the environment, will allow the company to eliminate unnecessary costs and to optimize employment. It will also help the company to fully use machines and equipment and production capacity. Thanks to these efforts, the company will be able to reduce production costs and increase operating profit, thus survive in a turbulent environment.

Aluminium is one of the environmental factors that may have an impact on Alzheimer's and Parkinson's disease. Some epidemiological studies show a relationship between the concentration of aluminium in drinking water and the incidence of Alzheimer's disease. The article presents and discusses the results of research on the effect of the type and dose of non-prehydrolyzed aluminium coagulants on the concentration of residual aluminium in water intended for human consumption. Aluminium sulphate (VI) and sodium aluminate were tested as coagulants. Analysis of the obtained test results showed that lower concentrations of residual aluminium were found after coagulation with aluminium sulphate (VI), which is hydrolyzed acidally, lowering the pH of the water in the range of 7.47 to 7.12 providing good conditions for the formation of Al(OH)3. A less useful coagulant due to the concentration of residual aluminium was sodium aluminate, which undergoes basic hydrolysis creating conditions for the transition of Al(OH)3 into soluble Al(OH).

In this study, we chose 61 plots along three randomly placed transects in urban and natural areas to examine Paralaudakia caucasia habitat preferences. Ten habitat characteristics found to affect the lizard occurrence were recorded in both habitat types. Based on ANOVA, distance to farmland, height of vegetation cover, percentage of cover of human structures, and slope orientation are significantly different between presence and absence plots. Using Principal Component Analysis, we found that the distance to farmland was the main factor predicted species presence in natural habitats. In urban habitats, the percentage of human structures was more important than other factors in predicting P. caucasia presence. The species is more abundant in regions with a low percentage of human-made structures. Other informative factors for species presence were distance from farmland and distance between refuges for urban and natural populations, respectively. Urban populations of P. caucasia appear to prefer areas outside of the city center, far from human structures, whereas natural populations appear to prefer areas away from villages where they may find higher densities of safe refuges. Isolated rocks in both urban and natural areas have an important role in predicting species presence acting because they act as refuges.

Rośliny w trakcie ewolucji dostosowały się do siedlisk, w których obecnie bytują. W wyniku wytworzenia różnorodnych mechanizmów na poziomie anatomiczno-fizjologicznym oraz molekularnym potrafią one reagować na naturalne zaburzenia występujące w środowisku. W ostatnich dziesięcioleciach obserwuje się jednak intensywne, kierunkowe zmiany warunków środowiskowych spowodowane działalnością człowieka. W obliczu tych zmian duża część roślin staje przed poważnym problemem związanym z przetrwaniem w granicach ich naturalnego zasięgu, z powodu zbyt małej tolerancji na zachodzące zmiany. W konsekwencji, globalne zmiany środowiska w dużym stopniu przyczyniają się do gwałtownego spadku bioróżnorodności ekosystemów lądowych w skali kuli ziemskiej. Artykuł przedstawia mechanizmy dostosowujące rośliny do głównych zmian warunków środowiskowych takich jak: susza, spadek odczynu gleby oraz wzrost temperatury na Ziemi.

Plants are organisms deprived of the ability to actively move. The adaptations they created during the evolution allow them to survive adverse habitat changes. The recent decline in the diversity of plants on the globe is caused by changes in the environment too quickly. These processes lead to the extinction of plant populations without giving them time to create appropriate adaptations. In connection with the observed decline in biodiversity, it seems that research into the possibilities of adaptation of plants to changes in habitat conditions is extremely important for understanding the functioning of ecosystems and the protection of endangered species. The article focuses on the main mechanisms adapting plants to environmental changes such as: drought, decrease in soil pH and increase in temperature on the Earth.

The intermediate timescale study (2012–2016, from May to October) was conducted in the Western Polish Carpathians where Inceptisols predominate. The splash erosion rate (kg m−2) was variable and showed a strong correlation with environmental factors, including rainfall parameters, land use (black fallow, meadow), slope gradient (0°, 11°), and also the particle size of soil and usage time (organic matter content, OM). The splash erosion rate on the slope with black fallow was 95 times higher than in the meadow and up to 20 times higher than in flat area. The average downslope splash erosion was 75% higher than the upslope splash erosion, and the soil particles were detached to maximum heights of 50 cm (downslope). There was a positive correlation between splash erosion and wash and a negative correlation between splash erosion and OM.
