Passive remote sensing (RS) of solar-induced chlorophyll fluorescence (SIF) of vegetation is feasible at ground level, airborne level and space borne level with certain prototypes. Fraunhofer Line Discrimination (FLD) and its improved methods have been widely used to extract SIF. Unlike processing at ground level, these methods do not work so well since it is not easy to obtain the solar incide...

OBJECTIVE To assess psychological stress in primary caregivers of juvenile idiopathic arthritis (JIA) pediatric patients. METHODS Uncontrolled cross-sectional analytical study of 40 caregivers of JIA patients. Caregivers were evaluated using the Caregiver Burden Scale, which analyzes five domains of stress on a scale of 1 to 4: general strain, isolation, disappointment, emotional involvement ...

This paper presents the experimental work conducted on Conventional Basin type Solar Still in order to investigate the effect of some design and operating parameters on the performance of the still. The vapour leakage from the still may significantly vary the performance, lot of literature can be found on this topic. The misalignment or crookedness of distillate channel may be seemingly ignorab...

This longitudinal study examined individual patterns and changes in /s/ + stop cluster simplifications of six normally developing children. Subjects produced selected words containing initial voiced and voiceless stops and /s/ + stop clusters at monthly intervals. Speech samples were transcribed phonetically, and voice onset times (VOT) of the stop consonants were measured. The results revealed...

One of the key impediments to wide utilization solar water desalination systems is limited production. Hence, this study aims at increasing thermal performance a single-slope still by surface area evaporation and absorption exposed sunlight. A hollow rotating cylinder was installed inside structure; modified system then joined with an outside heater for productivity improvement. The obtained re...

The end of the last solar cycle was at least 3 years late, and to date, the new solar cycle has seen mainly weaker activity since the onset of the rising phase toward the new solar maximum. The newspapers now even report when auroras are seen in Norway. This paper is an update of our review paper written during the deepest part of the last solar minimum [1]. We update the records of solar activ...

Solar technology offers great potential in terms of supplying the world’s energy needs. However, its current contribution to the world is still limited. The main factor is related to high initial cost of building the system. This paper will provide an up-to-date review of solar concentrators and their benefits to make solar technology affordable. It will also analyse on some of the existing sol...
