Design of a programmable rainfall simulator [PDF]

1993 (25th) Southeastern Symposium on System Theory, 2002
A programmable controller (PIC) was designed to provide a greater flexibility in rainfall simulator research. The PIC controlled the rainfall simulator using a process control board employing a microprocessor. This control board provided programmable capability previously unavailable in field research. Software to control the system was developed using

Introgressed Variation in TaMYB7‐A1 Drives Graded Dormancy and Climate‐Adaptive Pre‐Harvest Sprouting Resistance in Wheat

Advanced Science, EarlyView.
TaMYB7‐A1 directly activates TaABI5 to enhance ABA signaling and regulate ABA‐GA homeostasis, enforcing seed dormancy. Its superior allele, derived from wild einkorn introgression, harbors a MITE insertion that elevates expression and two amino acid substitutions that enhance transcriptional activity, collectively generating graded PHS resistance for ...

A Controlled Rainfall Simulator

Journal of Physics: Conference Series
Abstract This study presents the design, integration, and performance evaluation of a controlled rainfall simulator developed as an add-on for a landslide simulation system. The simulator generates rainfall intensities from 0 to 20 mm/h, adjustable via a web interface, and operates using six spraying cycles per hour.

Simulation of monthly rainfall totals

ANZIAM Journal, 2008
The observed distribution of non-zero rainfall totals for a given month is often modelled using a maximum likelihood estimate for the Gamma distribution. In this paper we show that a Gamma distribution can be regarded as a zero order approximation to a density distribution constructed by a series of associated Laguerre polynomials.

Errors and uncertainties in microwave link rainfall estimation explored using drop size measurements and high-resolution radar data

, 2010
Microwave links can be used for the estimation of path-averaged rainfall by using either the path-integrated attenuation or the difference in attenuation of two signals with different frequencies and/or polarizations.

Highly Efficient and Environmentally Stable Radiative Cooling Fabric: Integrating Photoluminescence and Hierarchical Core–Shell Fibers

Advanced Science, EarlyView.
A scalable radiative cooling fabric engineered with a multi‐layer assembly core–shell structure and integrated photoluminescent materials is reported. The fabric exhibits remarkable environmental stability, including UV resistance, mechanical durability, hydrophobicity, stain resistance, thermal stability, and flame retardancy, demonstrating its ...

Efeito de escarificação e da erosividade de chuvas sobre algumas variáveis de valores de erosão hídrica em sistemas de manejo de um nitossolo háplico Effect of chiseling and rainfall erosivity on some characteristics of water erosion in a nitosol under distinct management systems

Revista Brasileira de Ciência do Solo, 2008
O preparo do solo altera as suas condições físicas de superfície e subsuperfície e, conseqüentemente, influencia os valores de propriedades que se relacionam com a erosão hídrica.

Chitosan‐Carbon Dot Composite Materials Form a Leaf Surface Barrier to Mitigate the Enrichment and Invasion of Nanoplastics: From Leaf Interface to Systemic Response

Advanced Science, EarlyView.
Foliar spraying of CS‐CDs can form a film on the leaves of Brassica rapa, effectively reducing the enrichment and absorption of PS in the leaves, while increasing the biomass and nutrient content of the plants. In addition, CS‐CDs can also enrich the interfoliar microbial community and activate the plant's own defense metabolic pathways.

Restauração da estrutura do solo por sequências culturais implantadas em semeadura direta, e sua relação com a erosão hídrica em distintas condições físicas de superfície Restoration of the soil structure by crop sequences established in no-till, as related to water erosion in distinct surface physical conditions

Revista Brasileira de Ciência do Solo, 2010
A estrutura do solo desempenha papel de destaque no crescimento de plantas e no controle da erosão e, por conseguinte, na produção de alimentos e na conservação do solo e da água. Considerando isso, realizou-se este trabalho com o objetivo de implementar

Impacts of sugarcane (Saccharum sp.) soil and fertiliser management practices on nutrients and sediment in plot-scale runoff from simulated rainfall

, 2021
Runoff of nutrients and sediment from agricultural catchments can impair the health and resilience of aquatic ecosystems in receiving waterbodies. The sugarcane (Saccharum sp.) industry in Australia has adopted strategies to improve farm runoff water ...
