Opis:
The main purpose of this article is presentation of the concept of deservingness, which means dividing people into those who deserve to be supported and those who do not. In the paper, the deservingness models are analysed – the CARIN framework, the deservingness heuristic model and the RICE principles. The CARIN framework consists of five criteria – Control, Attitude, Reciprocity, Identity and Need, the RICE model of four criteria – Reciprocity, Identity, Control and Effort, and the deservingness heuristic model is based on the inherent ability to distinguish between ‘cheaters’ and ,’reciprocators’ in creating common good in society. The deservingness of particular groups and the influence of individual characteristics on its perception are also presented.
Głównym celem artykułu jest przedstawienie pojęcia zasługiwalności, które w kontekście polityki społecznej oznacza dzielenie ludzi na tych, którzy zasługują na wsparcie, i tych, którzy nie są go godni. W opracowaniu dokonano analizy modeli zasługiwalności – modelu CARIN, heurystycznego modelu zasługiwalności oraz modelu RICE. Model CARIN składa się z pięciu kryteriów zasługiwalności – kontroli, postawy, wzajemności, tożsamości i potrzeby, model RICE z czterech kryteriów – wzajemności, tożsamości, kontroli i wysiłku, natomiast heurystyczny model zasługiwalności bazuje na wrodzonej zdolności do określania wkładu innych w kształtowanie dobra wspólnego. W artykule zaprezentowano również zasługiwalność w kontekście różnych grup beneficjentów oraz określono wpływ cech indywidualnych na postrzeganie zasługiwalności.

Opis:
The potential of rice husks powder (RHP), for the removal of Congo red dye from aqueous solution was investigated. Batch adsorption studies were conducted and various parameters such as contact time, adsorbent dosage, initial dye concentration, pH and temperature were studied to observe their effects in the dye adsorption process. The optimum conditions for the adsorption of CR onto the adsorbent (RHP) was found to be: contact time (100 min) pH (10.0) and temperature (303 K) for an initial dye concentration of 50 mg/l and adsorbent dose of 1.0 g respectively. The experimental equilibrium adsorption data fitted best and well to the Freundlich Isotherm model for both dyes adsorption. The maximum adsorption capacity was found to be 33.88 mg/g for the adsorption of CR dye. The kinetic data conformed to the pseudo second order kinetic model. Thermodynamic quantities such as Gibbs free energy (ΔGº), enthalpy (ΔHº) and entropy (ΔSº) were evaluated and the negative values of ΔGº, ΔHº and ΔSº obtained indicate the spontaneous and exothermic nature of the adsorption process.

Opis:
This study focuses on determinants of the agricultural loan decision-making process of rice (Oryza sativa) farmers in Abuja, Nigeria, using the Heckman two-stage model and factor analysis. This study was designed specifically to achieve the following objectives: determine the socio-economic profiles or characteristics of rice farmers, analyze the costs and returns of rice production, evaluate factors influencing rice farmers’ decision to obtain an agricultural loan, evaluate socio-economic factors influencing the amount of the agricultural loan, and determine the constraints or problems facing rice farmers. A multi-stage sampling design was employed. A total sample of one hundred (100) rice farmers was included, and primary data were utilized. Data were obtained through the use of a well-structured and well-designed questionnaire. Statistical and econometric tools used in analyzing data included descriptive statistics, gross margin analysis, financial analysis, the Heckman two-stage model, and principal component analysis. The results show that 63% of rice farmers were between the age of 31–50 years. The mean age was 41.90 years. About 65% of rice farmers were male, and 54% of them were married. Also, 93% of rice farmers had formal education and were literate. The household sizes were large, with an average of six persons per household. An average of 71,550 nairas was the loan amount granted to rice farmers by financial institutions. The average farm size amounted to 1.49 hectares. Factors influencing the decision of rice farmers to obtain agricultural loan included age (P < 0.01), marital status (P < 0.05), household size (P < 0.10), educational level (P < 0.05), farm size (P < 0.05), farm and non-farm income (P < 0.10), farm experience (P < 0.05), collateral property (P < 0.05), extension services (P < 0.10), and awareness of loan or credit facilities (P < 0.05). Rice production was profitable with a net farm income of 744,300 nairas. The gross margin ratio of 0.95 means that 95 kobos covered profits, taxes, expenses, interest, and depreciation for every naira invested in rice production activities. Socio-economic factors statistically and significantly influencing the amount of agricultural loan obtained by rice farmers included (P < 0.05) sex (P < 0.01), household size (P < 0.05) and educational level (P < 0.01). The constraints facing rice farmers in obtaining the agricultural loan and production activities included lack of collateral property, lack of fertilizer input, poor-quality feeder roads, lack of credit facilities, inadequate labor input, and complicated and costly administrative procedures to obtain a loan. It is recommended that agricultural loans be made available to rice farmers in sufficient amounts and at low-interest rates. Also, farm inputs, fertilizer inputs, improved seeds, and chemicals should be made available to rice farmers.

Opis:
Rozdrabnianie materiałów biologicznych jest procesem energochłonnym. W trakcie dekohezji ziarna występuje złożony stan naprężeń wywołany; ściskaniem, skręcaniem, zginaniem, rozrywaniem, pękaniem, ścieraniem czy ścinaniem. W pracy podjęto próbę poszukiwania rozwiązań konstrukcyjnych zespołu rozdrabniającego i sterowania procesem w kierunku podwyższenia funkcjonalności rozdrabniania ryżu: sprawności, energooszczędności i równomierności.
Grinding of biological materials is a very energy consuming process. Grain decohesion involves complex strain phenomenon resulting from squeezing, twisting, bending, cracking, tearing apart or cutting. The search of constructional solutions of grinding set and process control, aiming at making rice grinding process more efficient in terms of its flexibility, energy saving and regularity was undertaken in the paper.

Opis:
The water supply deficit requires agro-environmental rationale for the use of alternative water sources to feed agricultural crops, viz.: industrial wastes, municipal drains, farm animal waste, drainage and escape water of rice irrigation systems. We analyzed the quality of irrigation water from different sources, with regard to the content of cations, anions, water-soluble salts, power of hydrogen (рН), sodium adsorption ratio (SAR), etc. in it. In the course of the greenhouse trial, we diagnosed its impact on the indicator crop (maize) (Zea mays L.) with its herbage crop stage of 10 leaves, supplied with water of varying quality. We proved the viability of improved drainage and escape water from rice irrigation systems in irrigated agriculture, owing to which maize herbage was diminished, on average, by 5.82%. We verified the negative impact of irrigation water, which contains the effluent disposals of metallurgical production, on croppers – it had contributed to diminishing the watered maize herb, on average, by 39.27%. A correlation analysis of the test data proved the closely interrelated feedback between the maize herbage amount and the content of cations, anions and water-soluble salts in irrigation water (coefficient of correlation r varied between 0.88 and 0.98). The worked-out linear regressive model for maize herbage, based on the content of water-soluble salts in irrigation water, together with SAR index (Y=2342.71–1.82×x1+366.78×x2), affirmed the validity of the pattern, discovered by means of the correlation analysis.
