Abstract:

Red pumpkin beetle (Aulacophora africana Weise) is an important defoliator and vector of pathogens to its numerous crop hosts. Control had largely been by synthetic insecticides with their attendant consequences on man and the environment thus necessitating scientific studies on environmental-friendly management strategies. The experiment was conducted in the Research Farm of Federal University Wukari in the month of May 2019 with the aim of evaluating the attractiveness of A. africana to Light-emitting diode (LED) and Incandescent Light bulb colours.

Abstract:

Recently, we have seen energy-efficient light-emitting diode (LED) light bulbs rapidly replace incandescent ones. However, results of new research are indicative of adverse health impacts of LED lighting, which is characterized by enriched blue light. Our study aims to reveal whether using color priming by attaching red/green traffic-light icons on light bulbs influences consumers’ preferences of light bulbs. We conducted a field study simulating the buying process, in which participants (N = 572) were presented with LED and carbon incandescent bulbs. We alternately displayed two pairs of bulb

Abstract Videoplethysmography is currently recognized as a promising noninvasive heart rate measurement method advantageous for ubiquitous monitoring of humans in natural living conditions. Although the method is considered for application in several areas including telemedicine, sports and assisted living, its dependence on lighting conditions and camera performance is still not investigated enough. In this paper we report on research of various image acquisition aspects including the lighting spectrum, frame rate and compression. In the experimental part, we recorded five video sequences in

Abstract:

In the recent development of LED technologies and market growth of LED luminaries, further study is needed in order for LEDs to replace the current incandescent bulb. Because of the LED radiation pattern, and it being a point-type light source, LED luminaries must employ similar and different methods than those of other luminaries in order to achieve a uniform irradiance. The methods presented in this paper can fasten the production of luminaries while cutting cost and still make luminaries with over 80% uniform irradiance. To achieve these methods reflectors, of 97% reflectivity, of multiple

The article applies both semiconductor thermoelectric power generation technology and micro heat pipe array heat dissipation technology to the utilization of waste heat from high heat flux density devices, achieving waste heat recovery and power generation from high heat flux density devices. High heat flux density devices have high heat flux density, micro heat pipe arrays have good heat dissipation ability, while semiconductor thermoelectric power generation technology requires high heat flux density to ensure efficient power generation. This article combines the three organically to achieve

The response of <em>Culicoides</em> biting midges, mosquitoes and other dipterans to different wavelengths was evaluated in a farm meadow in northern Spain. A total of 9449 specimens of 23 species of <em>Culicoides</em>, 5495 other ceratopogonids (non-biting midges), 602 culicids and 12428 other mixed dipterans were captured. Centers for Disease Control and Prevention (CDC) suction light traps fitted with five light emitting diodes (LEDs) (white, green, red, blue, ultraviolet) were run for 15 consecutive nights. Significantly more <em>Culicoides</em> were collected in

Boron-doped TiO2-ZnO nanocomposite was prepared by sonochemically using boron trichloride, tetra n-butyl orthotitanate and zinc acetate in appropriate proportion. The as-prepared nanocomposite was successfully characterized by XRD, EDX, SEM and BET techniques The operational factors that affect the rate of photocatalytic degradation of methyl violet 10B present in wastewater were optimized, which include initial dye concentration, catalyst amount, pH level and different light intensities such as incandescent light bulb, UV lamp and sunlight.

The mare is a seasonally polyoestrous long-day breeder with a physiological breeding season lasting from April–October in the Northern Hemisphere. The hypothalamic-pituitary-gonadal axis in the mare is subject to a circannual endogenous rhythm that is primarily regulated by day length. Increasing ambient photoperiod in the spring alters the pattern of melatonin secretion. The resulting stimulation of hypothalamic gonadotropin-releasing hormone secretion triggers pituitary follicular stimulating hormone release and follicular growth.

Abstract:

Confocal microscopy has been shown to produce improved lateral and axial image resolution compared with conventional microscopy. Image degradation due to scattering is reduced since only those portions of the specimen in the focal plane of the objective will contribute to image formation at the light detector. Previous work has shown that slit apertures can be used instead of pinholes to achieve the advantages of confocal microscopy with increased illumination and deceased scan line artifact. Slit scanning microscopes are also simpler in design than pinhole scanners but their aperture forms an

Abstract:

Sintering is an extremely flexible process where micro-scale particles are bonded together through heat and pressure, and is often used to work elements that are compounds with unworkably high melting temperatures. The technology has been used in basic form for thousands of years through its fundamental role in the production of ceramics and the strengthening of bricks. It is the process that allows ceramics to harden into a range of different useful structures in the kiln oven. During the 19th century, our understanding of the mechanics of sintering vastly expanded through visionaries such as

Abstract:

The invention of the incandescent light bulb by Edison in 1879, led to the introduction of the laparo-thoracoscope in 1910. Attempts were made to use this device in the knee joint as well. Development of the arthroscope really took off after the introduction of “cold-light” and rod lens optical system by Hopkins in 1960. Kenji Takagi and later Masaki Watanabe get the credit for developing the modern form of arthroscopy. The spillover of knee arthroscopy into the shoulder was inevitable and began in 1980’s. Shoulder arthroscopy started with instability repair, followed by subacromial decompress
