Bachelor Of Science
A Bachelor of Science (BS, BSc, B.S., B.Sc., SB, or ScB; from the Latin ') is a bachelor's degree that is awarded for programs that generally last three to five years. The first university to admit a student to the degree of Bachelor of Science was the University of London in 1860. In the United States, the Lawrence Scientific School first conferred the degree in 1851, followed by the University of Michigan in 1855. Nathaniel Shaler, who was Harvard's Dean of Sciences, wrote in a private letter that "the degree of Bachelor of Science came to be introduced into our system through the influence of Louis Agassiz, who had much to do in shaping the plans of this School." Whether Bachelor of Science or Bachelor of Arts degrees are awarded in particular subjects varies between universities. For example, an economics student may graduate as a Bachelor of Arts in one university but as a Bachelor of Science in another, and occasionally, both options are offered. Some universities follo ...

Bird Studies Canada
Birds Canada (formerly Bird Studies Canada) is Canada's national bird conservation organization. Birds Canada began as the ''Long Point Bird Observatory'' in 1960, changing its name in 1998 to reflect the growing national scope of its research programs. The name was changed again in 2019 to Birds Canada. Its mission is to advance the understanding, appreciation and conservation of wild birds and their habitats through studies that engage the skills, enthusiasm and support of volunteers, members, staff and the interested public. Birds Canada conducts a wide range of local, regional, national and international programs, dependent upon the active involvement of thousands of volunteers dubbed "Citizen Scientists", guided by a small group of professional scientists. Its national headquarters are located near Port Rowan and Long Point, Ontario, Canada. Motus wildlife tracking network is a program of Birds Canada, it was launched in 2014 in the US and Canada, by 2022 more than 1,500 ...

Biological Species Concept
A species () is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. It is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour, or ecological niche. In addition, palaeontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. About 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomen". The first part of a binomen is the name of a genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes in zoological nomenclature). For ...

British Standard Cycle
British Standard Cycle (BSC or BSCy or CEI) is a British Imperial screw thread standard. Unlike other major British imperial thread standards (British Standard Whitworth and British Standard Fine) the thread runs at a 60 degrees rather than a 55 degrees angle. All sizes inch and larger use 26 threads per inch (tpi), making them similar to 1 mm ISO threads, which are 25.4 per inch and also run at a 60 degrees angle. It was originally used with both bicycles and motorcycles. However it is now believed to be obsolete in motorcycle manufacture. In the bicycle industry it is still found on virtually all bottom bracket threads and the wheel axles of low-end models manufactured in China, which are derived from pre-WWII British roadsters. BS 811: 1950 provides specifications for British standard cycle threads. Cycle thread in and inch sizes also come in 20 tpi and 24 tpi options. 1/4" diameter cycle thread nuts and bolts have the same 26tpi as 1/4" BSF, wh ...

Bristol Stool Chart
The Bristol stool scale is a diagnostic medical tool designed to classify the form of human faeces into seven categories. It is used in both clinical and experimental fields. It was developed at the Bristol Royal Infirmary as a clinical assessment tool in 1997, by Stephen Lewis and Ken Heaton and is widely used as a research tool to evaluate the effectiveness of treatments for various diseases of the bowel, as well as a clinical communication aid;Bristol scale stool form. A still valid help in medical practice and clinical research G Riegler, I Esposito – ''Techniques in coloproctology'', 2001 – Springer including being part of the diagnostic triad for irritable bowel syndrome. Interpretation The seven types of stool are: * Type 1: Separate hard lumps, like nuts (difficult to pass) * Type 2: Sausage-shaped, but lumpy * Type 3: Like a sausage but with cracks on its surface * Type 4: Like a sausage or snake, smooth and soft (average stool) * Type 5: Soft blobs with cl ...

Bright Star Catalogue
The Bright Star Catalogue, also known as the Yale Catalogue of Bright Stars, Yale Bright Star Catalogue, or just YBS, is a star catalogue that lists all stars of stellar magnitude 6.5 or brighter, which is roughly every star visible to the naked eye from Earth. The catalog lists 9,110 objects, of which 9,095 are stars, 11 are novae or supernovae (which were "bright stars" only at the time when they were at their peak), and four are non-stellar objects which are the globular clusters 47 Tucanae (designated HR 95) and NGC 2808 (HR 3671), and the open clusters NGC 2281 (HR 2496) and Messier 67 (HR 3515). The catalogue is fixed in number of entries, but its data is maintained, and it is appended with a comments section about the objects that has been steadily enhanced. The abbreviation for the catalog as a whole is BS or YBS but all citations of stars it indexes use HR before the catalog number, a homage to the catalog's direct predecessor, published ...

Biological Stain Commission
The Biological Stain Commission (BSC) is an organization that provides third-party testing and certification of dyes and a few other compounds that are used to enhance contrast in specimens examined in biological and medical laboratories. The BSC is a century-old organization well known to many thousands of scientists, worldwide but especially in N America, who buy BSC-certified stains for staining Staining is a technique used to enhance contrast in samples, generally at the Microscope, microscopic level. Stains and dyes are frequently used in histology (microscopic study of biological tissue (biology), tissues), in cytology (microscopic ... microscopic preparations and for making selective culture media for bacteria. Manufacturers and other vendors submit samples from their batches of dyes to the BSC's independent laboratory in Rochester NY. The BSC's certification label on a bottle of dye indicates that the contents are from a batch that passed the tests for chemical puri ...

Biological Safety Cabinet
A biosafety cabinet (BSC)—also called a biological safety cabinet or microbiological safety cabinet—is an enclosed, ventilated laboratory workspace for safely working with materials contaminated with (or potentially contaminated with) pathogens requiring a defined biosafety level. Several different types of BSC exist, differentiated by the degree of biocontainment they provide. BSCs first became commercially available in 1950. Purposes The primary purpose of a BSC is to serve as a means to protect the laboratory worker and the surrounding environment from pathogens. All exhaust air is HEPA-filtered as it exits the biosafety cabinet, removing harmful bacteria and viruses. This is in contrast to a laminar flow clean bench, which blows unfiltered exhaust air towards the user and is not safe for work with pathogenic agents. Neither are most BSCs safe for use as fume hoods. Likewise, a fume hood fails to provide the environmental protection that HEPA filtration in a BSC would pr ...

Binary Synchronous Communications
Binary Synchronous Communication (BSC or Bisync) is an IBM character-oriented, half-duplex link protocol, announced in 1967 after the introduction of System/360. It replaced the synchronous transmit-receive (STR) protocol used with second generation computers. The intent was that common link management rules could be used with three different character encodings for messages. Six-bit Transcode looked backward to older systems; USASCII with 128 characters and EBCDIC with 256 characters looked forward. Transcode disappeared very quickly but the EBCDIC and USASCII dialects of Bisync continued in use. At one time Bisync was the most widely used communications protocol and is still in limited use in 2013. Framing Bisync differs from protocols that succeeded it in the complexity of message framing. Later protocols use a single framing scheme for all messages sent by the protocol. HDLC, Digital Data Communications Message Protocol (DDCMP), Point-to-Point Protocol (PPP), etc. e ...

Binary Symmetric Channel
A binary symmetric channel (or BSCp) is a common communications channel model used in coding theory and information theory. In this model, a transmitter wishes to send a bit (a zero or a one), and the receiver will receive a bit. The bit will be "flipped" with a "crossover probability" of ''p'', and otherwise is received correctly. This model can be applied to varied communication channels such as telephone lines or disk drive storage. The noisy-channel coding theorem applies to BSCp, saying that information can be transmitted at any rate up to the channel capacity with arbitrarily low error. The channel capacity is 1 - \operatorname H_\text(p) bits, where \operatorname H_\text is the binary entropy function. Codes including Forney's code have been designed to transmit information efficiently across the channel. Definition A binary symmetric channel with crossover probability p, denoted by BSCp, is a channel with binary input and binary output and probability of error p. That ...

California Building Standards Commission
The California Building Standards Commission (CBSC) is authorized by the state of California, through the California Building Standards Law, to manage the many process relating to development, adoption, approval, publication, and implementation of California's building codes. Created in 1953 by the California Building Standards Law, the CBSC falls under the California Department of General Services within the California Government Operations Agency. The commission is formally defined under the ''California Building Standards Law.'' The California Building Standards Code, is the foundation for the design and implementation of building codes within California. The building codes include the implementation of improved safety methods, sustainability measures, consistency, new technology and construction methods, and reliability. These codes are revamped every 18 months through the Triennial and Intervening Code Adoption Cycle. These implementations are paramount to the development of b ...
