This paper covers the post-harvest aspects, processing and quality assurance for speciality/organic coffee products. It starts with the origins of coffee, what aspects provide inherent quality, and diseases that deter quality. It then touches on coffee harvesting, the timing for harvesting and development of fruit color. It discusses picking systems, both manual and mechanical and their effects...

We describe a single microfluidic device and two methods for the passive storage of aqueous drops in a continuous stream of oil without any external control but hydrodynamic flow. Advantages of this device are that it is simple to manufacture, robust under operation, and drops never come into contact with each other, making it unnecessary to stabilize drops against coalescence. In one method th...

Models like DRAINMOD and its forestry version, DRAINLOB, have been specifically developed as a field scale model for evaluating hydrologic effects of crops (trees), soil, and water management practices for lands with pattern drainage (i.e. with parallel ditches) on relatively flat, high water table soils. These models conduct a water balance between the ditches to predict water table depths, dr...

OBJECTIVES To examine the effect of prolonged application time on the early and 3-year resin-dentin microtensile bond strength. METHODS Water/ethanol (Single Bond [SB]) and acetone-based systems (One Step [OS]) were employed. A flat superficial dentin surface was exposed in third human molars by wet abrasion. The adhesives were applied to a delimited area of 52 mm2 on wet surfaces, for 40, 90...

OBJECTIVE To determine the effect of semen storage and separation techniques on sperm DNA fragmentation. DESIGN Controlled clinical study. SETTING An assisted reproductive technology laboratory. PATIENT(S) Thirty normoozospermic semen samples obtained from patients undergoing infertility evaluation. INTERVENTION(S) One aliquot from each sample was immediately prepared (control) for the ...

Hydrogen storage is a main issue in the establishment of hydrogen economy. Geo-storage could be viable solution if injected into and withdrawn from suitable geological formations, reversibly reliably. Rock wettability major factor as it affects injectivities, withdrawal rates, capacities, containment security. We report here contact angles brine on surface bituminous coal pressurized atmosphere...

Background and Aim: There is a gap of information on the effect of time, disinfectant, and storage conditions on the dimensional stability of direct post patterns made of self-cure acrylic resins. This study assessed the effect of Deconex® and wet or dry stor-age conditions on the dimensional stability of post patterns made of Duralay and GC acrylic resins. Materials and Methods: Sixty spe...

During the rice harvesting season in Thailand, large amounts of fresh paddy are sent to rice mills immediately after harvesting due to a lack of proper farm storage space. At certain levels of moisture content, rice grains may generate hazardous gases, which can replace oxygen (O(2)) in the confined spaces of underground rice mill pits. This phenomenon has been observed in a fatal accident in T...

It is well known that egg storage reduces embryo performance, but the fundamental reasons for reduced embryo quality remain unclear. The objective of this study was to investigate possible cellular and molecular mechanisms that might reduce embryo quality after egg storage. Broiler hatching eggs were obtained from the Ross 308 broiler strain, divided into 2 groups, and stored (4 and 14 d) under...

Removal of fly ash using wet scrubbers is widely used in the small and medium scale industries. Among the wet scrubbing methods, spray column falls into the simplest type category for its simple construction and various advantages. A novel pilot plant wet scrubber has been conceived, designed and fabricated. This paper distinctly focuses on the detailed design and fabrication of the ejector, wh...
