Abstract: In maize growing technologies, tillage technological operations are the most time-consuming and require the greatest fuel input. Substitution of conventional tillage, involving deep ploughing, by other reduced tillage methods can reduce technological production costs, diminish soil degradation and environmental pollution from greenhouse gas emissions, as well as improve economic competitiveness of agricultural produce.
Experiments designed to assess energy and environmental aspects associated with different reduced tillage systems, applied in maize cultivation were conducted at Aleksandras Stulginskis University taking into account Lithuania’s economic and climate conditions. The study involved 5 tillage treatments: deep ploughing (DP, control), shallow ploughing (SP), deep cultivation (DC), shallow cultivation (SC) and no-tillage (NT).
Our experimental evidence suggests that with the application of reduced tillage systems it is feasible to reduce fuel consumption by 13-58% and working time input by 8.4% to nearly 3-fold, to reduce the cost price of maize cultivation technological operations, decrease environmental pollution with CO2 gas by 30 to 146 kg ha-1, compared with the deep ploughing.
Abstract: This paper discusses our preliminary experiences in the design of a user interface of a computerized content-rich vocational training courseware meant for users with little or no computer experience. In targeting a growing population with limited access to skills training of any sort, we faced numerous challenges, including language and cultural differences, resource limits, gender boundaries and, in many cases, the simple lack of trainee motivation. With the size of the unskilled population increasing much more rapidly than the numbers of sufficiently skilled teachers, there is little choice but to develop teaching techniques that will take advantage of emerging computer-based training technologies. However, in striving to serve populations with minimal computer literacy, one must carefully design the user interface to accommodate their cultural, social, educational, motivational and other differences. Our work, which uses computer based and haptic simulation technologies to deliver training to these populations, has provided some useful insights on potential user interface design approaches.
Abstract: Impact of adopting products promoted by the Consortium for Improving Agriculture-based livelihoods in Central Africa (CIALCA) on food and nutrition security was tested. Multi-stage sampling was used to select 7 project mandate areas, 5 villages/mandate area (stratified into action, satellite and control sites) and 913 households. Structured questionnaires were administered; analysis of impact based on comparison between stratums, differences in means tested by ANOVA and significance of difference obtained by Tukey's HSD multiple rank tests. Perception of adequate food sufficiency received a higher rating in action and satellite sites compared to control sites reason being improved agricultural technologies. For >60% of households, worsened food security was due to climatic conditions. Although a higher proportion of households in action and satellite was meeting calorie RDIs in DRC and Burundi the difference was insignificant from control sites. 53% of respondents in control sites indicated a decrease in intake of protein rich foods, this was significantly higher than the proportion in the action (46%) and satellite (41%) sites.
Abstract: Background and objectives: Most of the agricultural products are processed by blanching. Blanching can increase antioxidant activity in white saffron products. The objective of this research were to determine antioxidant activity, to identify, and to measure changes in phenolic substances of fresh and blanched white saffron rhizomes (Curcuma mangga Val.). Methods: White saffron rhizomes were peeled, washed and blanched in boiling water containing 0% or 0.05% citric acid solution for 5 and 10 minutes. Samples were extracted using methanol, rotaevaporated, and freezedried. Dried extract was determined antioxidant activity by DPPH method, identified and quantified for the phenolic substances by High Performance Liquid Chromatography (HPLC) equipped with coloumn C18 and Photodiode-array detector (PAD). Result: This research showed that the quantity of the 6 phenolic substances identified in blanched white saffron in citric acid solution increased significantly compared to that of the non-blanched. Blanching white saffron in 0.05% citric acid media for 5 minutes increased its antioxidant activity, and total phenolic content. Conclusions: The identified phenolic substances of white saffron were Gallic Acid (GA), Catechin (C), Epicatechin (EC), Epigallocatechin (EGC), Epigallocatechingallat (EGCG) and Gallocatechingallat (GCG). The blanched white saffron contained C and EGCG significantly higher than that of fresh rhizomes.
Abstract: This work assessed some properties of three pedons on a toposequence in Ijah-Gbagyi district in Niger State, Nigeria. The pedons were designated as JG1, JG2 and JG3 representing the upper, middle and lower slopes respectively. The surface soil was characterized by dark yellowish brown (10YR3/4) color at the JG1 and JG2 and very dark grayish brown (10YR3/2) color at JG3. Sand dominated the mineral fraction and its content in the surface horizon decreased down the slope, whereas silt content increased down the slope due to sorting by geological and pedogenic processes. Although organic carbon (OC), total nitrogen (TN) and available phosphorus (P) were rated high, TN and available P decreased down the slope. High cation exchange capacity (CEC) was an indication that the soils have high potential for plant nutrients retention. The pedons were classified as Typic Haplustepts/ Haplic Cambisols (Eutric), Plinthic Petraquepts/ Petric Plinthosols (Abruptic) and Typic Endoaquepts/ Endogleyic Cambisols (Endoclayic).
Abstract: The purpose of the study is to analyze the main tourism attraction in indigenous tribes, as well as for the development of tribal aboriginal tourism brings positive and negative impacts. This study used qualitative research methods, and Lilang, Tbulan, and Hrung three tribes as the object of investigation. The results showed that: 1. Because three tribes geographical proximity, but have their own development characteristics, not conflict situations. 2. Three tribes are located in National Scenic Area and National Forest Recreation Area near, so driven tribal tourism development. 3 In addition Hrung three tribal tribal no major attraction, mainly located in the provision of accommodation; another Lilang and Tbulan tribe has natural resources and cultural resources attraction. 4 in the tourism brings positive and negative impacts, respondents expressed positive than residents of negative impacts. Based on the above findings, this study not only provides advice for tribal tourism operators, but also for future research to provide specific directions.
Abstract: Purpose: To compare attitudes and perceptions of
Israeli native born mothers versus former Soviet Union (FSU)
immigrant mothers regarding the physical health of their infant.
Methodology: cross-sectional design. A convenience sample of 50
participants was recruited by face to face and snowball technique. A
questionnaire was constructed according to the instructions of the
Ministry of Health for the care and treatment of infants. The main
areas explored were: sources of knowledge that the young mother
acquired regarding the care of her infant, ways of caring for the
infant, hygiene and sanitary habits, and the pattern of referral to
health professionals. The last topic relates to emotions mothers might
experience towards their infant.
Results: Mothers from both cultural groups present some similar
caring behaviors, which may express a universal aspect of mothers'
behavior towards their infants. However, immigrant mothers differ
significantly from native born by relying less on their mothers' and
grandmothers' experience, they wean their infants from diapers
earlier, they are stricter about hygiene and sanitary habits and they
tend to consult a physician when their infant has low fever. Native
born and immigrant mothers differ in their expressions of pride and
wonder. Immigrant mothers report of a lesser degree of these
emotions towards their infants than native born mothers.
Conclusion: The theoretical model of socialization and
acculturation of immigrant mothers is employed as an explanatory
model for the current findings Young immigrant mothers undergo a
complex acculturation process and adapt behavioral patterns in
various areas to comply with Israeli norms and values, demonstrating
assimilation. In other areas they adhere to the norms of their original
culture.
Abstract: Petroglyphs, stone sculptures, burial mounds, and
other memorial religious structures are ancient artifacts which find
reflection in contemporary world culture, including the culture of
Kazakhstan. In this article, the problem of the influence of ancient
artifacts on contemporary culture is researched, using as an example
Kazakhstan-s sculpture and painting. The practice of creating
petroglyphs, stone sculptures, and memorial religious structures was
closely connected to all fields of human existence, which fostered the
formation of and became an inseparable part of a traditional
worldview. The ancient roots of Saka-Sythian and Turkic nomadic
culture have been studied, and integrated into the foundations of the
contemporary art of Kazakhstan. The study of the ancient cultural
heritage of Kazakhstan by contemporary artists, sculptors and
architects, as well as the influence of European art and cultures on the
art of Kazakhstan are furthering the development of a new national
art.
Abstract: This paper present lease agreement regulations in
selected European countries. The lease agreement has a long history
and now is one of the main ways to manage agricultural lands in
Europe. The analysis of individual regulations, which has been done,
indicates that this agreement is very important to build social
relations in agriculture and society. This article provides an analysis
of the legal regulations concerning the lease in France, Spain,
Switzerland, Ukraine and Italy. Article is example of study of the
legal regulations and can be used for legal changes in individual
countries.
Abstract: The protection of groundwater resources is the great
important many semiarid and arid environments. Baghan watershed
is located in the north of Kangan in the Boshehr province in Iran. The
groundwater resources have a vital role in supplying agricultural,
drinking, domestic and industrial water demand in Baghan
watershed. For our investigation into the water quality we collected
30 samples to chemical and physical analysis. The result showed the
marl and evaporation deposits that contain anhydrite and gypsum is
the main source of groundwater pollution, and one part of the
groundwater was polluted by oil and gas industrial. Another part of
the groundwater was contaminated by urban waste water. The
electrical conductivity and captions and anions increased around of
towns and gas refinery. Although the negative impact of untreated
domestic wastewater is relatively low but the results showed strongly
the negative impact of wastewater refinery is very considerable. This
negative impact increased in downstream due to shallow aquifer.
Additionally, the agents that adversely affect the quality of
groundwater come from a variety of sources, including geology,
domestic wastewater and the Jam refinery in Baghan watershed.
Abstract: This paper explores the idea of globalisation and
considers accounting-s role in that process in order to develop new
spaces for accounting research. That-s why in this paper we are
looking for questions not necessary for answers. Adopting an
'alternative' view of accounting it-s related to the fact that we sees
accounting as social and evolutionist process, that pays heed to those
voices arguing for greater social and environmental justice, and that
draws attention to the role of accounting researchers in the process of
globalisation. The paper defines globalisation and expands the
globalisation and accounting research agenda introducing in this
context the harmonization process in accounting. There are the two
main systems which are disputing the first stage of being the
benchmark: GAAP and IFRS. Each of them has his pluses and
minuses on being the selected one. Due to this fact a convergence of
the two, joining the advantages and disadvantages of the two should
be the solution for an unique international accounting solution. Is this
idea realizable, what steps has been made until now, what should be
done in the future. The paper is emphasising the role of the cultural
differences in the process of imposing of an unique international
accounting system by the global organizations..
Abstract: Post-disaster reconstruction projects offer
opportunities to facilitate physical, social and economic development
and to reduce future hazard vulnerability long after the disasters.
Sustainability of post-disaster reconstruction project conducted in the
villages of Dinar following the 1995 earthquake was investigated in
this paper. Officials of the Government who were involved in the
project were interviewed. Besides, two field surveys were done in 12
villages of Dinar in winter months of 2008. Beneficiaries were
interviewed and physical, socio-cultural and economic impacts of the
reconstruction were examined. The research revealed that the postdisaster
reconstruction project has negative aspects from the point
view of sustainability. The physical, socio-cultural and economic
factors were not considered during decision making process of the
project.
Abstract: the article analyzes the national security as a scientific and practical problem, characterized by the state's political institutions to ensure effective action to maintain optimal conditions for the existence and development of the individual and society. National security, as a category of political science reflects the relationship between the security to the nation, including public relations and social consciousness, social institutions and their activities, ensuring the realization of national interests in a particular historical situation. In national security are three security levels: individual, society and state. Their role and place determined by the nature of social relations, political systems, the presence of internal and external threats. In terms of content in the concept of national security is taken to provide political, economic, military, environmental, information security and safety of the cultural development of the nation.
Abstract: The aim of this study the analysis of Turkic culture and their influence on personality. We also discussed the role of history in Turkic folk development. Thereby cultural and anthropological context of ancient Turkic sources reveal concept of the "person". In the article have been analyzed ethnical, cultural, ethnical philosophical content of the world conception of the ancient Turks.
Abstract: At present the process of formation of corporate
values in Kazakh universities is under the influence of a whole range
of socio-economic and cultural changes: on the one hand universities
must maintain and transmit traditional cultural values of education,
on the other, to improve quality of service and to involve young
people to science, providing thus own competitiveness. Thus, this
article presents some results of two cycles of sociological research
conducted in 2012 and aimed at identifying possible ways to
popularize science and readiness to participate of youth in given
activities, expectations of young scientists and the prospects of future
development of the Kazakh science.
Abstract: Fishing has always been an essential component of
the Polynesians- life. Fishhooks, mostly in pearl shell, found during
archaeological excavations are the artifacts related to this activity the
most numerous. Thanks to them, we try to reconstruct the ancient
techniques of resources exploitation, inside the lagoons and offshore.
They can also be used as chronological and cultural indicators. The
shapes and dimensions of these artifacts allow comparisons and
classifications used in both functional approach and chrono-cultural
perspective. Hence it is very important for the ethno-archaeologists
to dispose of reliable methods and standardized measurement of
these artifacts. Such a reliable objective and standardized method
have been previously proposed. But this method cannot be envisaged
manually because of the very important time required to measure
each fishhook manually and the quantity of fishhooks to measure
(many hundreds). We propose in this paper a detailed acquisition
protocol of fishhooks and an automation of every step of this method.
We also provide some experimental results obtained on the fishhooks
coming from three archaeological excavations sites.
Abstract: The use of plastic materials in agriculture causes
serious hazards to the environment. The introduction of biodegradable materials, which can be disposed directly into the soil
can be one possible solution to this problem. In the present research results of experimental tests carried out on biodegradable film
fabricated from natural waste (corn husk) are presented. The film was
characterized by Fourier transform infrared spectroscopy (FTIR),
differential scanning calorimeter (DSC), thermal gravimetric analysis
(TGA) and atomic force microscope (AFM) observation. The film is
shown to be readily degraded within 7-9 months under controlled soil
conditions, indicating a high biodegradability rate. The film
fabricated was use to produce biodegradable pot (BioPot) for
seedlings plantation. The introduction and the expanding use of
biodegradable materials represent a really promising alternative for
enhancing sustainable and environmentally friendly agricultural
activities.
Abstract: The excessive use of agricultural pesticides and the
resulting contamination of food and beds of rivers have been a
recurring problem nowadays. Some of these substances can cause
changes in endocrine balance and impair reproductive function of
human and animal population. In the present study, we evaluated the
possible effects of the fungicide cuprous copper oxide Sandoz® on
pregnant Wistar rats. They received a daily oral administration of 103
or 3.103 mg/kg of the fungicide from the 6th to the 15th day of
gestation. On day 21 of gestation, the maternal and fetal toxicity
parameters and indices were determined. The administration of
cuprous oxide (Copper Sandoz) in Wistar rats, the period of
organogenesis, revealed no evidence of maternal toxicity or embryo
at the studied doses.
Abstract: Evapotranspiration (ET) is a major component of the hydrologic cycle and its accurate estimation is essential for hydrological studies. In past, various estimation methods have been developed for different climatological data, and the accuracy of these methods varies with climatic conditions. Reference crop evapotranspiration (ET0) is a key variable in procedures established for estimating evapotranspiration rates of agricultural crops. Values of ET0 are used with crop coefficients for many aspects of irrigation and water resources planning and management. Numerous methods are used for estimating ET0. As per internationally accepted procedures outlined in the United Nations Food and Agriculture Organization-s Irrigation and Drainage Paper No. 56(FAO-56), use of Penman-Monteith equation is recommended for computing ET0 from ground based climatological observations. In the present study, seven methods have been selected for performance evaluation. User friendly software has been developed using programming language visual basic. The visual basic has ability to create graphical environment using less coding. For given data availability the developed software estimates reference evapotranspiration for any given area and period for which data is available. The accuracy of the software has been checked by the examples given in FAO-56.The developed software is a user friendly tool for estimating ET0 under different data availability and climatic conditions.
Abstract: Heavy metal transfer in soil profiles is a major
environmental concern because even slow transport through the soil
may eventually lead to deterioration of groundwater quality. The use
of sewage sludge and effluents from wastewater treatment plants for
irrigation of agricultural lands is on the rise particularly in peri-urban
area of developing countries. In this study soil samples under sludge
application and wastewater irrigation were studied and soil samples
were collected in the soil profiles from the surface to 100 cm in
depth. For this purpose, three plots were made in a treatment plant in
south of Tehran-Iran. First plot was irrigated just with effluent from
wastewater treatment plant, second plot with simulated heavy metals
concentration equal 50 years irrigation and in third plot sewage
sludge and effluent was used. Trace metals concentration (Cd, Cu)
were determined for soil samples. The results indicate movement of
metals was observed, but the most concentration of metals was found
in topsoil samples. The most of Cadmium concentration was
measured in the topsoil of plot 3, 4.5mg/kg and Maximum cadmium
movement was observed in 0-20 cm. The most concentration of
copper was 27.76mg/kg, and maximum percolation in 0-20 cm.
Metals (Cd, Cu) were measured in leached water. Preferential flow
and metal complexation with soluble organic apparently allow
leaching of heavy metals.
