Isparta rose is an agricultural product that provides world-wide awareness to our country, offering social and cultural aspects and touristic and economic contributions. Turkey and Bulgaria are two major countries that produce rose for economic return. Isparta rose (rose damascena) is a therapeutic fragrant flower used in aromatherapy applications besides oil production. The aim of this study is to determine the energy and cost analysis of drying of rose (Rosa damascena). Additionally, the energy consumption and unit cost of screening and separation was determined. Experiments were carried out in the Yakaören Rose Oil Factory of Gülbirlik, which was established in the village of Yakaören in the center of Isparta province. Temperatures of 45oC and 55oC were chosen as drying temperature in the experiment. According to the results of the research, work capacity for temperatures of 45°C and 55°C were 0.32 kgh-1 and 0.63 kgh-1, respectively. Specific energy consumption (SEC) for the same temperatures were 2.48 kWhkg-1 and 8.96 kWhkg-1, respectively. Specific moisture extraction rates (SMER) were found to be 0.402 and 0.112 kgkWh-1. The unit drying cost was for the two drying temperatures of 45 oC and 55 °C are 0.51 and 1.84 Turkish liras (TL), respectively. As a result; ...
Generated wastes require space and financial outlays on their proper storage and processing, whereas the lack of means usually leads to depositing wastes in places not meant for this purpose. Illegal dumping sites still emerge, despite introducing in Poland the obligatory (common) fee for collection and management of wastes and the obligatory establishing the Selective Waste Collection Points in each district. The aim of the work was conducting a detailed inventory of illegal dumping sites in the area of Olsztyn district (situated in the Silesia province, on the Krakow-Częstochowa Upland) and indicting the morphological composition of the wastes deposited in these places. The paper presents a detailed analysis of the morphological composition of illegal landfill sites situated in the analyzed district. The investigations located 28 illegal dumping sites, despite the fact that a Selective Municipal Waste Collection Point operates in the district area. The analysis of location, area, mass and composition of the wastes was conducted for each illegal landfill, according to the methodology developed for this purpose. Over a half of the illegal dumping sites was situated in the forest and on 4 of them the estimated mass of dumped waste exceeded 1Mg. Debris constitutes the highest proportion (21.8%) ...
Drying of sultana grape fruits was studied using a microwave dryer under the laboratory environment at the Department of Agricultural Machinery and Technologies Engineering at Suleyman Demirel University. In this study, the effects of microwave drying and fan assisted microwave drying on drying time, drying ratio of grape samples were examined. Sultana grape fruits were dried by using microwave, microwave-convective combination and convective drying, respectively. The effects of microwave drying (180, 540 and 720 W); combined convective and microwave drying (180W-100ºC, 360W-100ºC and 540 W-100ºC), convective drying (100, 150, 200ºC) on drying time, drying rate of grape samples have been investigated. The drying data were applied to four different mathematical models, namely, Midilli-Kucuk, Weibull distribution, logistic and Alıbas Equation Models. The performances of these models were compared according to the coefficient of determination (R2), standard error of estimate (SEE) and residual sum of squares (RSS), between the observed and predicted moisture ratios. The drying characteristic curves were estimated against four mathematical models and the Weibull distribution was found to be the best descriptive model for all the drying experiments of thin layer grape fruit samples except for 540W-100ºC. Alıbas model equation was also found to be the best descriptive model ...
The aim of this article was to present the rules governing the waste management system (WMS) and identify the changes emerging as a result of new regulations being introduced by example of Wołomin commune. European, Polish and Czech regulations clearly indicate the value of the hierarchy of waste management (WM). A response to the amended law was the modification of the WMS in communes, including the Wołomin commune. Based on performed analysis and discussions, it can be stated that the municipal waste management system (MWMS) in the commune of Wołomin meets the requirements imposed by the legislator, works efficiently and positively influences the condition of the natural environment. In addition, the information obtained has been generalized and compared with the situation in the Czech Republic (CR). ...
The article presents the possibility of using a cell phone to control the level of carbon dioxide in undercover tunnels and greenhouses. Studies show that increasing the level of carbon dioxide in the air under covers results in a significant increase in the yield of the crops produced. The proposed system is autonomous. Its essential element is the multimedia Raspberry Pi platform. Under the manufacturer's assumptions, the Raspberry Pi is a microcomputer designed primarily for the operation of audio-visual equipment. It can also be used to build simple measurement systems and control systems such as the access control system. This article describes the basic features of the platform along with the extended modules. The proposed application is used to measure the CO2 content in the air in the cultivation tunnel. The system also measures temperature and relative humidity. The measured values are compared with the threshold values and the report is sent to the mobile phone selected by the user. The developed program reports on the values recognised as threshold ones. In response to the information received, the user may decide to remotely enable the increase of CO2 content in the air under cover. The motion sensor integrated with the ...
The aim of our work on the Kysuce region was to map the incidence of preserved TAL elements, assessment of their contemporary usage and assessment of the threat to them under the influence of anthropogenic and natural stress factors. To do so, it was crucial to understand space and time intersection of TAL existence, the interaction of socio-economic, abiotic and biotic systems of the landscape and assess correctly the contemporary trends of the evolution of society and the threat to the agrarian heritage resulting from it. High proportion of TAL, covering 12% of the whole area, is typical for the monitored region. There were two types of TAL: TAL with dispersed settlement, covering 2261.4 ha of the area (3%) and TAL of arable-land, grasslands, covering 6990.3 ha of the area (9%). In the agricultural country, TAL makes up for important stabilizing elements and their presence increases biodiversity in these regions. It is of high importance to classify TAL as significant landscape features that are important as local bio-centres (because of their benefits for society and the environment). ...
Common dandelion Taraxacum officinale agg. (T. officinale F.H. Wigg) is a plant species commonly found on urban areas. It is characterised by low habitat requirements and proven bioindication properties. The aim of this study was to assess the possibility of using T. officinale agg. for monitoring of the urban soils in the City of Kielce with regard to selected heavy metal concentrations, i.e. Pb, Cu and Zn. Twenty-one soil and dandelion samples (roots and leaves) were collected from the area of Kielce. The study areas were designated with regard to land-use types, i.e. industrial areas, urban parks and forests, urban green areas, and urban allotment gardens. The total heavy metal concentrations were determined in the soil and plant material by the ICP-AES (inductively coupled plasma atomic emission spectroscopy) method, after mineralisation of the samples in a mixture of HCl-HNO3 (3:1). Moreover, the soil samples were analysed in terms of pH values. The concentrations of heavy metals in the analysed soils were oscillating at: 16.5-290 mg/kg d.m. for Pb; 7.11-41 mg/kg d.m. for Cu; 55.7-338 mg/kg d.m. for Zn In the case of dandelion leaves, the concentration range was recorded at: 1.07-3.11 mg/kg d.m. for Pb; 3.11-14.1 mg/kg d.m. for ...
The purpose of that article was to show the significance of water as the source of plant pathogens, and need of it effective disinfection methods in modern agriculture and horticulture. The increase in the cost of agricultural water use for crop irrigation and the necessity of using the same water several times, as well as the changing climatic conditions, including prolonged shortage of atmospheric precipitation and often extreme temperatures during the summer, necessitate the selection of an effective, easy to apply and economical method of disinfecting recirculated water to eliminate or minimize the occurrence of the most serious plant pathogens inhabiting various water sources. Among them, microorganisms of the genera Phytophthora, Pythium and Fusarium, and the species Rhizoctonia solani, Verticillium dahliae and some pathogenic bacteria pose the most serious threat. Some of them can be found in rivers, streams, ponds and water reservoirs, others are soil-borne pathogens that cause root and stem base rot of many plant species. The available literature describes at least a dozen methods of water disinfection, among them slow filtration through sand or lava filters, chlorination and heating. The literature data indicates that the use of sand filters is the most effective, safe and cheapest ...
The most of the on site wastewater treatment systems in Poland discharges treated effluent to the soil. The goal of phosphorus (P) reduction from dispersed sources of pollution can be achieved by application of P reactive materials in the construction of wastewater infiltration systems. Two P reactive materials were tested in this study: Polonite® in grains of 26 mm and lightweight aggregate Leca® in grains of 410 mm. Apparent P sorption capacity was assesed on 40.9 mg·g-1 (Polonite®) and 5.1 mg·g-1 (Leca®). Both materials sorbed P-PO4 very fast, after 15 min over 90% of P was removed from solution and wastwater. Wastewater used in this study came from the outlet from the septic tank of on site septic system. P-PO4 solution was prepared from KH2PO4 and the tap water. In the small column experiment, four collumns (2 filled with Polonite® and 2 filled with Leca®) were fed with wastewater and P-PO4 solution in hydraulic loadings of 3040 dm3·m-2·d-1. All the columns removed significant amounts of P from both solution and wastewater with the reduction between 28.3% and 72.5%. The mean P-PO4 effluent concentrations ranged from 1.21 mg·dm-3 to 7.12 mg·dm-3. The best overall performance was achieved by the Polonite® fed ...
Erosion is a natural phenomenon which constantly changes the shape of the Earth's surface, yet it is regarded as a very serious harmful factor by people in view of their economic and investments activities. Ski slopes are a special example of areas with a serious erosion hazard due to a permanent deforestation, considerable longitudinal slopes, engineering works, levelling ski slopes, but also because of abundant surface runoff. The aim of the research was to compare the extent of potential soil erosion in deforested areas intended for ski slopes, with various anti-erosion measures implemented, as well as to discuss the possibility of RUSLE erosion model application under these conditions.The researched objects were ski runs on the eastern slopes of Mount Jaworzyna Krynicka (The Beskid Sądecki Mts.). Potential erosion was computed in the areas of seven ski slope segments in four variants of the area cover and applied anti-erosion measures. Some computational data (the ski slope area, average slope gradients, soil granulometric composition) were obtained from the Forest Digital Map and Digital Terrain Model, whereas numerical indicators used for the model were established on the basis of the subject literature.Under presented conditions, potential erosion losses were greatly diversified. The biggest losses, expressed ...
The paper presents an analysis of sewage susceptibility to biodegradation on an example of sewage treatment plant in Wodzisław Śląski in the Śląskie province. For this purpose, dependencies between selected indices of domestic sewage pollution were applied. Descriptive statistics of the respective indices rations COD/BOD5, BOD5/TN, BOD5/TP were presented. Moreover, an analysis was conducted on the composition of raw sewage flowing into the treatment plant, pre-treated sewage and sewage leaving the studied treatment plant. The analysis was carried out on the basis of three basic indices of sewage pollution (BOD5, COD and total suspended solids) and two biogenic indices (total nitrogen and total phosphorus). Tests on the sewage composition were conducted in the years 2010-2015. Basic descriptive statistics were compiled for the values of the studied indices of sewage pollution and the obtained results were interpreted. On the basis of collected material it may be said that sewage reaching the treatment plant in Wodzisław Śląski revealed a good susceptibility to biodegradation, whereas the BOD5/TN and BOD5/TP ratios were below the optimum value. ...
Percentage of wind energy production in Poland increases every year. In 2009 it amounted to 0.55%, while in 2014 it was already 4.53%. Localization and construction of wind farms must meet many conditions defined in regulations being in force in this field, they still arouse a lot of controversy. Main reasons are their negative impact on landscape, agritourism, land value, human health, nature and others. Every such investment has both positive and negative influence on the neighbourhood, and its development. It gives an income to communes' budgets through taxes, to landowners through grounds lease or sale, creates new workplaces during construction and then operation of devices. It also leads to modernization and repair local routes, electrical grids and others .The aim of this paper is to present chosen problems connected to the localization of wind farms. The research focuses on regulations concerning the wind farms localization , its procedures, calculation of taxes for communes, incomes for landowners on whose grounds the wind turbines were built, and others, in the context of the new law i.e. Act of 20 May 2016 on Wind Energy Investments. ...
Implementation of infrastructural investments is a key factor contributing to the development potential of a region. The current law in force, regulating the implementation of infrastructural public purpose investments, simplifies the actions leading to terrain acquisition for road investments.The research shows a significant dependence between access to public roads and demand for storage facilities. From an entrepreneur's point of view, the necessary condition for further development is implementation of infrastructural investments. Locating the investments in the vicinity of traffic routes is a strategic decision, closely related to the field of business. Too long distances combined with poor condition of road infrastructure generate additional transport costs. This fact is directly reflected in the limited economic and development potential of particular regions.In the studied case, the theoretical value of statistics (27.868) is almost a half of the calculated value (54.27). Therefore, the null hypothesis is rejected. Calculations carried out at assumed significance level α = 0.0005, clearly prove, that there is a close correlation between the size of the company, and the choice of the location of the additional storage space with regard to access to infrastructure such as public roads. The carried out analysis confirms the fact, that the enterprise size ...
The aim of the research was the evaluation of sprinkler irrigation and nitrogen fertilization on some selected features of the quality of malt and wort from ‘Marthe' and ‘Mauritia' malting barley grains. The field experiment was carried out in the years 2010-2012 at the Research Station of the University of Science and Technology in Mochełek near Bydgoszcz. As a result of 3-year field experiment and laboratory test of grain, malt and wort, it was found that introducing sprinkler irrigation into the production process of malting barley is a step justified by the obtained quality effects. It was found that in the case of irrigated malting barley cultivations nitrogen fertilization at the rate of 30 kg∙ha-1 provides (in relation to control, non-irrigated treatment) the highest values of such parameters as weight of the technical barley crops, content of protein, extractivity of Pilsen type malt, amount of obtained wort and simplified mashing efficiency. The combination of sprinkler irrigation of malting barley plants with their nitrogen fertilization at the increased rates of 60 and 90 kg∙ha-1, resulted in the following effect - high mass of the usable grain of crops remained but their quality deteriorated. Malt produced from malting barley fertilized with nitrogen ...
Considerations on the needs and opportunities of introducing multidimensional cadastre have been carried out for several years all over the world, including Poland. The European Union provides the Member States with a legal framework in the form of a standard governing the development of widely understood land administration systems. The cadastre as a source of information about the lands and their owners must first of all enable the proper management of the land. The basic aspect that we encounter in the discussion on the cadastre is the identification of the land parcel and the rights in rem of particular subjects. Registration of rights in the layer system is the core of a multi-dimensional cadastre. Harmonization of all regulations affecting the functioning of the cadastre will be a basic condition of a 3D cadastral parcel definition and creation of a multidimensional cadastre in Poland. The paper proposes a layer system of cadastral parcels, which derives from the current definition of parcel, taking into account the ownership of a traditional parcel along with the space above and below the ground and its constituent parts. ...
The concept of real estate legal status has not been explicitly defined by the legislator. Despite this, the literature took the view that this is generally the rights and restrictions assigned to the property. To determine legal status one should determine first the entities which has rights to the property. For the purpose of determining the legal status of real estate, mortgage registers are established in Poland. Unfortunately, at this moment, a large part of the properties, particularly in rural locations do not have established mortgage registers. In the absence of mortgage registers other documents showing ownership of the property may be land ownership acts. For agricultural properties, they are sometimes the only documents on the basis of which one can specify the entities to which it has rights in rem to real estate, they are also the basis for founding the mortgage register.In recent years the number of new mortgage registers increased significantly in real estate of rural areas. The basis for establishing the mortgage register in addition to the documents confirming the acquisition of rights is also data shown in the Land and Property Register, which are the basis for determination of the property. Due to the fact ...
