The amino acid sequence of the constant (C) domain of the light chain of the mouse myeloma protein M315 has not been identified so far in any other myeloma protein. In this study, serological analysis with antiserum to the C-domain of this light chain (L315) showed that approximately equal to 1% of Igs in normal mouse serum have L chains of the L315 type (called lambda2). Corroborative evidence...

Bricks are a widely used construction and building material around the world. Bricks are prepared from natural waste material which comprises of orange peels and coconut waste. Clay is used as a binding material for natural waste material and paper mill waste. The main objective of the present study is to reduce the quantity of clay with natural waste material. The orange peels and coconut wast...

A small fract ion of the l ight (L) 1 chains of mouse immunog lobu l ins (Igs) are of the X-type (1). O f the -~ 22 X-chains from mouse mye loma tumors whose amino acid sequences have been pa r t i a l ly or fully de te rmined , all bu t one have the same constant (C) d o m a i n sequence (2, 3). T h e exception, L 3t5, is the l ight chain of the mye loma pro te in (M315) p roduced by p l a s m...

Artificial light is globally one of the most widely distributed forms of anthropogenic pollution. However, while both the nature and ecological effects of direct artificial lighting are increasingly well documented, those of artificial sky glow have received little attention.We investigated how city lights alter natural regimes of lunar sky brightness using a novel ten month time series of meas...

ect of window rooms on critically ill patients admitted to the ICU with subarachnoid hemorrhage, and concluded that the presence of a window in an ICU room did not improve their outcomes [1]. We commend the attempt to associate natural light with improved outcomes for hospitalized patients, but we have some concern as regards the data analysis and interpretation. Th e Hunt–Hess grade has been w...

All images are highly ambiguous, and to perceive 3-D scenes, the human visual system relies on assumptions about what lighting conditions are most probable. Here we show that human observers' assumptions about lighting diffuseness are well matched to the diffuseness of lighting in real-world scenes. We use a novel multidirectional photometer to measure lighting in hundreds of environments, and ...

The purpose of this study was to evaluate the effectivity of melatonin in addition to light treatment (exposure to 2 hours of light during the night = a long-day photoperiod) to modify the breeding season of Saanen and cross-bred milk goats and to compare the difference between the breeds. Twenty-two Saanen and 22 cross-bred does were randomly divided into 3 treatment groups. Group 1 (controls)...

Turf algae increasingly dominate benthic communities on coral reefs. Given their abundance and high dissolved organic carbon (DOC) release rates, turf algae are considered important contributors to the DOC pool on modern reefs. The release of photosynthetically fixed carbon as DOC generally, but not always, increases with increased light availability. Nutrient availability was proposed as an ad...
