Basal Electrical Rhythm
The basal or basic electrical rhythm (BER) or electrical control activity (ECA) is the spontaneous depolarization and repolarization of pacemaker cells known as interstitial cells of Cajal (ICCs) in the smooth muscle of the stomach, small intestine, and large intestine. This electrical rhythm is spread through gap junctions in the smooth muscle of the GI tract. These pacemaker cells, also called the ICCs, control the frequency of contractions in the gastrointestinal tract. The cells can be located in either the circular or longitudinal layer of the smooth muscle in the GI tract; circular for the small and large intestine, longitudinal for the stomach. The frequency of contraction differs at each location in the GI tract beginning with 3 per minute in the stomach, then 12 per minute in the duodenum, 9 per minute in the ileum, and a normally low one contraction per 30 minutes in the large intestines that increases 3 to 4 times a day due to a phenomenon called mass movement. The basal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Base Excision Repair
Base excision repair (BER) is a cellular mechanism, studied in the fields of biochemistry and genetics, that repairs damaged DNA throughout the cell cycle. It is responsible primarily for removing small, non-helix-distorting base lesions from the genome. The related nucleotide excision repair pathway repairs bulky helix-distorting lesions. BER is important for removing damaged bases that could otherwise cause mutations by mispairing or lead to breaks in DNA during replication. BER is initiated by DNA glycosylases, which recognize and remove specific damaged or inappropriate bases, forming AP sites. These are then cleaved by an AP endonuclease. The resulting single-strand break can then be processed by either short-patch (where a single nucleotide is replaced) or long-patch BER (where 2–10 new nucleotides are synthesized). Lesions processed by BER Single bases in DNA can be chemically damaged by a variety of mechanisms, the most common ones being deamination, oxidation, ...

Benign Early Repolarization
Benign early repolarization (BER) or early repolarization is found on an electrocardiogram (ECG) in about 1% of those with chest pain. It is diagnosed based on an elevated J-point / ST elevation with an end-QRS notch or end-QRS slur and where the ST segment concave up. It is believed to be a normal variant. Benign early repolarization that occurs as some patterns is associated with ventricular fibrillation. The association, revealed by research performed in the late 2000s, is very small. Types Benign early repolarization, very prevalent in younger people and healthy male athletes, can be divided into 3 subtypes: * Type 1 – BER pattern seen in lateral precordial leads. * Type 2 – BER pattern seen in inferior or inferolateral leads. * Type 3 – BER pattern seen globally (inferior, lateral, right precordial leads). Associations with serious conditions Research in the late 2000s has linked this finding to ventricular fibrillation, particularly in those who have fainted ...

Blossom End Rot
Calcium (Ca) deficiency is a plant disorder that can be caused by insufficient level of biologically available calcium in the growing medium, but is more frequently a product of low transpiration of the whole plant or more commonly the affected tissue. Plants are susceptible to such localized calcium deficiencies in low or non-transpiring tissues because calcium is not transported in the phloem. This may be due to water shortages, which slow the transportation of calcium to the plant, poor uptake of calcium through the stem, or too much nitrogen in the soil. Causes Acidic, sandy, or coarse soils often contain less calcium. Uneven soil moisture and overuse of fertilizers can also cause calcium deficiency. At times, even with sufficient calcium in the soil, it can be in an insoluble form and is then unusable by the plant or it could be attributed to a "transport protein". Soils containing high phosphorus are particularly susceptible to creating insoluble forms of calcium. Calcium a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Basic Encoding Rules
X.690 is an ITU-T standard specifying several Abstract Syntax Notation One, ASN.1 encoding formats: * #BER encoding, Basic Encoding Rules (BER) * #CER encoding, Canonical Encoding Rules (CER) * #DER encoding, Distinguished Encoding Rules (DER) The Basic Encoding Rules (BER) were the original rules laid out by the ASN.1 standard for encoding data into a binary format. The rules, collectively referred to as a ''transfer syntax'' in ASN.1 parlance, specify the exact Octet (computing), octets (8-bit bytes) used to encode data. X.680 defines a syntax for declaring data types, for example: booleans, numbers, strings, and compound structures. Each type definition also includes an identifying number. X.680 defines several ''primitive'' data types, for example: BooleanType, IntegerType, OctetStringType. (ASN.1 also provides for ''constructed'' types built from other types.) Types are associated with a ''class''. For example, the primitive types are part of the ''universal'' class. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bit Error Rate
In digital transmission, the number of bit errors is the number of received bits of a data stream over a communication channel that have been altered due to noise, interference, distortion or bit synchronization errors. The bit error rate (BER) is the number of bit errors per unit time. The bit error ratio (also BER) is the number of bit errors divided by the total number of transferred bits during a studied time interval. Bit error ratio is a unitless performance measure, often expressed as a percentage. The bit error probability ''pe'' is the expected value of the bit error ratio. The bit error ratio can be considered as an approximate estimate of the bit error probability. This estimate is accurate for a long time interval and a high number of bit errors. Example As an example, assume this transmitted bit sequence: 1 1 0 0 0 1 0 1 1 and the following received bit sequence: 0 1 0 1 0 1 0 0 1, The number of bit errors (the underlined bits) is, in this case, 3. The BER is 3 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Air Berlin
Air Berlin plc & Co. Luftverkehrs KG (), branded as airberlin or airberlin.com, was a major German airline. At its peak, it was Germany's second-largest airline after Lufthansa, as well as Europe's tenth-largest airline in terms of passengers carried. It was headquartered in Berlin and had hubs at Berlin Tegel Airport and Düsseldorf Airport. At the time of its insolvency, it was a member of the Oneworld airline alliance, having joined in 2012. The airline was originally founded by American interests in 1978 to provide airline service to West Berlin, a territory that could not legally be served by West German airlines such as Lufthansa due to political restrictions on East German airspace. In 1991, shortly after German reunification, Air Berlin became a German-owned company and shifted its core business to compete more directly with Lufthansa, eventually becoming one of Germany's biggest airlines. After years of losses, however, Air Berlin filed for insolvency in August 2017 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
