Multi-temporal variation in water consumption of summer maize as determined by the Water Transformation Dynamical Processes Experimental Device
A better understanding of the multi-temporal variation in evapotranspiration (ET) at different crop growth stages is the key for determining a reasonable irrigation schedule. In this study, a new device known as ‘Water Transformation Dynamical Processes Experimental Device’ (WTDPED) was used to monitor ET for maize under controlled environmental and groundwater conditions, and the ...

A matrix-based multilevel approach to identify functional protein modules
Identifying functional modules is believed to reveal most cellular processes. There have been many computational approaches to investigate the underlying biological structures (Bader and Hogue, 2003; Dhillon et al., 2005; Krogan et al., 2006; Ramadan et al., 2005; Xiong et al., 2005; Zhang et al., 2004). A spectral clustering method plays a critical role identifying functional modules in a yeast ...

Satellite-based estimation of actual evapotranspiration in the Buyuk Menderes Basin, Turkey
Evapotranspiration (ET) is one of the most important components of the hydrological cycle, but it is often the most difficult variable to determine at basin scale. Traditionally, ET is estimated using point-based measurements collected at meteorological stations, but the non-spatial nature of these measurements often leads to significant errors when utilized at watershed scale. In this study, ...

Aftermath of the Long-Term Application of Sludge and Water from a Sewage Treatment Plant to a Lemon Tree (Citrus limon) Plantation
The effect of sewage sludge application to agricultural soils in industrial countries (Raven and Loeppert 1997; Towers and Horne 1997) and that of the treated domestic and industrial effluents on plants (Hooda et al. 1997; Logan et al. 1997; Palacios et al. 1999; Samaras and Kallianou 2000, Weir and Allen 1997) have been ...

Validation of evapotranspiration and its long-term trends in the Yellow River source region
In this paper, the ground observations were compared to the ERA-Interim, NCEP-DOE AMIP-II Reanalysis, MODIS ET product, and emerging offline SEBS ET data sets in the Yellow River source region of the Tibet Plateau. In general, the slopes of linear least squares exhibit differences, with ERA-Interim, NCEP–DOE, MOD16, and SEBS slopes of 0.88 ± 0.05, 0.64 ± 0.07, 0.66 ± 0.17, and 1.24 ± 0.97 ...

A method of calibration and variance analysis with respect to the Penman-Monteith equation for the Turc, Hargreaves and Abtew potential evapotranspiration models
Introduction: The full ASCE/FAO-56 Penman-Monteith evapotranspiration (PM-ET) equation and crop coefficients are often employed for irrigation scheduling of open-field crops. To obtain PM-ET derived water-use figures requires access to full weather station datasets, which includes radiation, air temperature, wind-speed, and relative humidity measurements. Over the years there have been many ...

The ratio of transpiration to evapotranspiration in a rainfed maize field on the Loess Plateau of China
Maize (Zea mays L.) is a major crop on the Loess Plateau, and calculating the ratio of transpiration to evapotranspiration (T/ET) of maize is important for estimating field water balance. In this study, the sap flow method was adopted to measure transpiration (T) characteristics of maize. In order to calibrate the sap flow gauge, the sap flow rate was compared to the leaf T determined by the ...

Occupational hygiene at a drum composting plant in Hyvinkää, Finland
Refuse disposal and treatment must be safe for employees. Organic dust of waste origin, perhaps containing microbes, may be harmful to health. Microbes, especially fungi but also thermophilic Actinomycetes bacteria, may cause allergy and asthma (Terho et al. 1993; Madigan et al. 1997). Usually fungi cause hypersensitivity (Madigan et al. 1997) and the most common syndrome is allergic rhinitis ...

Effect of deficit irrigation and fertilization on cucumber
Soil water budgets are essential in determining the proper timing and amount of irrigation. Organic fertilizers can be substituted for commercial fertilizers; however, information is sparse on the interaction of irrigation management and nutrient source on cucumber (Cucumis sativus L.) production. This study evaluated nutrient source and irrigation management on growth and yield of cucumber grown ...

Composting of municipal green waste using a hybrid Mode of the aerated static pile
The aerated static pile (ASP) system developed in Rutgers University (Finstein et al., 1980) is based on a deep understanding of composting as a microbial process. It allows for a good degree of process control and high organic matter stabilisation rates, with relatively low labour and cost. For these reasons, the ASP system has been intensively studied with, among others, the following aims: ...

Estimation of maize evapotranspiration using extreme learning machine and generalized regression neural network on the China Loess Plateau
Accurately estimating crop evapotranspiration (ET) is essential for agricultural water management in arid and semiarid croplands. This study developed extreme learning machine (ELM) and generalized regression neural network (GRNN) models for maize ET estimation on the China Loess Plateau. Maize ET, meteorological variables, leaf area index (LAI), and plant height (hc) were continuously ...

Trials about composting of solid wastes from palm oil Mills in Indonesia
The solid wastes produced in palm oil mills are empty fruit bunch (EFB), mesocarp fibre, shell, and palm kernel cake. On an average the amount of EFB is 0,220 t of 1 t oil palm fruit bunch (Singh, 1994). In Indonesia, there will be about 2.9 million tonnes EFB (dry basis) in 2000 (Lubis et. al. 1994). At the moment, EFB in Indonesian palm oil mills are burnt in incinerators to reduce the mass and ...

Remote sensing estimation of actual evapotranspiration and crop coefficients for a multiple land use arid landscape of southern Iran with limited available data
The Gareh Bygone Plain is an arid area, south of Zagros Mountains, in Southern Iran, where a floodwater spreading project has been implemented for artificial recharge of groundwater. Knowledge/mapping of actual evapotranspiration for the mainland uses (natural pasture, irrigated crops and tree plantations) is of major importance for water management in this remote area. The Surface Energy ...

Compost maturity as expressed by phytotoxicity and Volatile organic acids
VOA in Composts Maturity is a qualitative trait of compost that may be expressed in a number of ways and is generally held to be relevant to plant performance. Volatile organic acids (VOA) have been cited to be responsible for phytotoxicity (plant growth suppression) when immature compost is used for growing plants (Manios et al., 1989). However, the production of VOA in compost has not been ...

Effects of biowaste compost amendment on soil microbial biomass and specific carbon turnover in agricultural soils
The importance of biowaste compost as organic fertilisers has become more emergent in the last years due to the increased production of compost produced from biowaste. The utilisation of organic fertilisers in agriculture improves the physical, chemical and microbial properties of soils (Allievi et al., 1993; Senesi, 1989). Amendment of compost affects several soil properties positively like e.g. ...

Identification of the fourth duplication of upstream IHH regulatory elements, in a family with craniosynostosis Philadelphia type, helps to define the phenotypic characterization of these regulatory elements
Craniosynostosis, caused by the premature fusion of one or more of the cranial sutures, can be classified into nonsyndromic or syndromic and by which sutures are affected. It affects 1 in 2,000‐2,500 children [Boulet et al., 2008]. Several craniosynostosis syndromes are associated with malformations of the digits, including craniosynostosis Philadelphia type (CP), a rare form of syndromic ...

Sustainable Management of Large Scale Irrigation Systems: A Decision Support Model for Gediz Basin, Turkey
While water on a global scale is plentiful, 97% of it is saline and 2.25% is trapped in glaciers and ice, leaving only 0.75% available in freshwater aquifers, rivers and lakes. About 70% of this fresh water is used for agricultural production, 22% for industrial purposes and 8% for domestic purposes. Increasing competition for water for domestic and industrial purposes is likely to reduce the ...
