In-situ soil moisture conservation: utilisation and management of rainwater for crop production
The salient results of in-situ soil water conservation technologies that have been found suitable for increasing soil moisture in the arid and semiarid lands of eastern Kenya are reviewed. The results showed that Zai pits, tumbukiza and deep tillage when used together with soil fertility improvement can increase crop yields by 4–10 times in comparison to conventionally cultivated fields. ...

Dynamics of the evolution of the genus of agrostis revealed by GISH/FISH
Genomic changes in related species undergoing human-driven and natural selection are important and biologically interesting. The genus Agrostis is an ideal model for studying the evolution of plants since it has not undergone artificial selection for the past thousands of years. Fluorescence in situ hybridization (FISH) or genomic in situ hybridization (GISH) technology is an effective method for ...

Technology Keeps Catfish Jumping and Profits Steady
Andy Jones compares the catfish industry to the jagged graph of a heartbeat displayed on an EKG machine. The peaks and valleys of that pulsating line are a vivid metaphor for the fluctuating fortunes of a seasonal business dependent on live animals and a dynamic market. Jones is in a good position to make the connection. As a second-generation catfish farmer, he’s seen firsthand the highs ...

Determining Preconsolidation Stress and Penetration Pore Pressures from DMT Contact Pressures
Over recent years, several geotechnical explorations in clay deposits have shown the flat dilatometer test (DMT) to provide reasonable estimates of in-situ overconsolidation ratio with depth. Why should the horizontal stress index (KD = initial contact pressure minus hydrostatic pressure normalized to the effective overburden stress) show an empirical trend with over consolidation ratio (OCR)? It ...

New Zealand Mussel Farm Uses Real-Time Salinity Monitoring to Reduce Impact of Harvesting Closures
Overview Westpac Mussels worked with IoT firm Adroit to deploy a data buoy equipped with the Aqua TROLL 500 to collect real-time salinity measurements. Live monitoring of salinity data helps the company ensure compliance while reducing the impact of harvesting closures due to weather events. Challenge Water quality monitoring is a necessity in shellfish farming, since filter feeders such as ...

History, achievements, and current status of genetic resources conservation
This paper has been written to look back at the early period of crop genetic resources conservation and inform readers of what has been achieved so far and what needs to be done in the future. The recognition of the value of crop genetic resources and early efforts at collecting germplasm by pioneer plant explorers, such as F.N. Meyer and N.I. Vavilov, and some of the strategies they employed are ...

Comparison of in situ DGT measurement with ex situ methods for predicting cadmium bioavailability in soils with combined pollution to biotas
To assess the capabilities of the different techniques in predicting Cadmium (Cd) bioavailability in Cd-contaminated soils with the addition of Zn, one in situ technique (diffusive gradients in thin films; DGT) was compared with soil solution concentration and four widely used single-step extraction methods (acetic acid, EDTA, sodium acetate and CaCl2). Wheat and maize were selected as tested ...

Bicatalytic multistep reactions en route to the one-pot total synthesis of complex molecules: easy access to chromene and 1,2-dihydroquinoline derivatives from simple substrates
By combining nanocatalysis and base-catalysis, a novel one-pot multistep process was found for the synthesis of substituted heterocycles of biological relevance from simple substrates. It is based on an initial Au/O2 oxidation of allylic alcohols followed by a base-catalysed tandem hetero-Michael/aldolisation/crotonisation with ortho-hydroxy or ortho-amino benzaldehydes. The flexibility of the ...

Polyphenol, conditioning, and conservation effects on protein fractions and degradability in forage legumes
Forage legume proteins were fractionated by the Cornell Net Carbohydrate and Protein System or ruminally incubated to assess how conditioning and conservation methods interact with polyphenols (condensed tannins or o-quinones) to alter protein degradability. The presence of polyphenols, conditioning by maceration rather than rolls, and conservation as hay rather than silage shifted protein ...

Friction at the Cohesionless Soil-Structure Interface: Effect of Various Parameters according to a Classic Study and a New Approach
A direct shear box, a ring shear apparatus, and a minipressuremeter are used: (1) to study the behavior of the cohesionless soil-structure interface; (2) to evaluate the friction mobilized at this interface. Tests have been carried out with a continual displacement of the structure in contact with the soil. The applied normal stress was kept constant during all tests. The influence of the ...

On the use of non-negative matrix factorisation to characterise wastewater from dairy processing plants
A portable field spectrometer was used to record the time-resolved ultraviolet/visible (UV/Vis) spectrum of the effluent stream at two different dairy processing plants (a Drier Plant and Cheese Factory). The spectra exhibited significant variability. As an alternative to the partial least squares regression methods usually used in the online UV/Vis field a non-negative matrix factorisation ...
