Petrovichi
Petrovichi (russian: Петро́вичи) is a rural locality (a village) in Shumyachsky District of Smolensk Oblast, Russia, located about '' In Memory Yet Green'' by Isaac Asimov, 1979, p.4 southwest of Moscow, south of St Petersburg, south of Smolensk, and east of the border between Belarus and Russia. Its population in 1998 was 215. The village is the birthplace of Isaac Asimov. Asimov left it at the age of three, with his parents and sister, emigrating to the United States. There is a stone memorial at the site of his birth. History The earliest recorded mention of Petrovichi is from 1403. In the Russian Empire, Petrovichi was a ''shtetl'' in Klimovichskiy Uyezd (an ''uyezd'' with the seat in Klimovichi) of Mogilev Governorate. The governorate, historically Belarusian land, was a part of the Empire's Northwestern Krai. Petrovichi's population was half Jewish, half Belarusian. It had both a church and a synagogue, each one with a school attached to it. Accordin ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Bachelor Of Science
A Bachelor of Science (BS, BSc, SB, or ScB; from the Latin ') is a bachelor's degree 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 Southgate 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 follow the Oxford a ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Julian Calendar
The Julian calendar, proposed by Roman consul Julius Caesar in 46 BC, was a reform of the Roman calendar. It took effect on , by edict. It was designed with the aid of Greek mathematicians and astronomers such as Sosigenes of Alexandria. The calendar became the predominant calendar in the Roman Empire and subsequently most of the Western world for more than 1,600 years until 1582, when Pope Gregory XIII promulgated a minor modification to reduce the average length of the year from 365.25 days to 365.2425 days and thus corrected the Julian calendar's drift against the solar year. Worldwide adoption of this revised calendar, which became known as the Gregorian calendar, took place over the subsequent centuries, first in Catholic countries and subsequently in Protestant countries of the Western Christian world. The Julian calendar is still used in parts of the Eastern Orthodox Church and in parts of Oriental Orthodoxy as well as by the Berbers. The Julian calenda ...

Hebrew Calendar
The Hebrew calendar ( he, הַלּוּחַ הָעִבְרִי, translit=HaLuah HaIvri), also called the Jewish calendar, is a lunisolar calendar used today for Jewish religious observance, and as an official calendar of the state of Israel. It determines the dates for Jewish holidays and the appropriate Torah reading, public reading of Weekly Torah portion, Torah portions, ''yahrzeits'' (dates to commemorate the death of a relative), and daily Psalm readings, among many ceremonial uses. In Israel, it is used for religious purposes, provides a time frame for agriculture, and is an official calendar for civil holidays, alongside the Gregorian calendar. The present Hebrew calendar is the result of a process of development, including a Babylonian calendar, Babylonian influence. Until the Tannaitic period (approximately 10–220 Common Era, CE), the calendar employed a new lunar phase, crescent moon, with an Intercalation (timekeeping), additional month normally added every two or ...

Civil Registry
Civil registration is the system by which a government records the vital events (births, marriages, and deaths) of its citizens and residents. The resulting repository or database has different names in different countries and even in different US states. It can be called a civil registry, civil register (but this is also an official term for an individual file of a vital event), vital records, and other terms, and the office responsible for receiving the registrations can be called a bureau of vital statistics, registry of vital records and statistics, registrar, registry, register, registry office (officially register office), or population registry. The primary purpose of civil registration is to create a legal document (usually called a ''certificate'') that can be used to establish and protect the rights of individuals. A secondary purpose is to create a data source for the compilation of vital statistics. The United Nations General Assembly in 1979 adopted the Convent ...

Mazel Tov
"Mazel tov" or "mazal tov" (Hebrew/Yiddish: , Hebrew: ''mazál tov''; Yiddish: ''mázl tov''; lit. "good fortune") is a Jewish phrase used to express congratulations for a happy and significant occasion or event. Etymology and pronunciation The word ''mazel'' comes from the Biblical Hebrew ''mazzāl'', meaning "constellation" or (in Mishnaic Hebrew) "astrological sign" and may be related to the verb נ-ז-ל meaning "to flow down". The phrase ''mazel tov'' first appears in Geonic Hebrew, where it means "positive astrological sign" or simply "good fortune." The Medieval Hebrew song ''siman tov u-mazel tov, yehe lanu ulkhol yisrael'' "A good sign, a good omen! Let it happen for us and for all Israel" was used to congratulate, and the phrase itself acquired a congratulatory usage in Yiddish and Hebrew by the early 19th century and was later incorporated into Modern Hebrew. The Yiddish and Ashkenazic pronunciation of ''mazel'' has the stress on the first syllable while the Mod ...

Postdoctoral Researcher
A postdoctoral fellow, postdoctoral researcher, or simply postdoc, is a person professionally conducting research after the completion of their doctoral studies (typically a PhD). The ultimate goal of a postdoctoral research position is to pursue additional research, training, or teaching in order to have better skills to pursue a career in academia, research, or any other field. Postdocs often, but not always, have a temporary academic appointment, sometimes in preparation for an academic faculty position. They continue their studies or carry out research and further increase expertise in a specialist subject, including integrating a team and acquiring novel skills and research methods. Postdoctoral research is often considered essential while advancing the scholarly mission of the host institution; it is expected to produce relevant publications in peer-reviewed academic journals or conferences. In some countries, postdoctoral research may lead to further formal qualificati ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Biochemistry
Biochemistry or biological chemistry is the study of chemical processes within and relating to living organisms. A sub-discipline of both chemistry and biology, biochemistry may be divided into three fields: structural biology, enzymology and metabolism. Over the last decades of the 20th century, biochemistry has become successful at explaining living processes through these three disciplines. Almost all areas of the life sciences are being uncovered and developed through biochemical methodology and research. Voet (2005), p. 3. Biochemistry focuses on understanding the chemical basis which allows biological molecules to give rise to the processes that occur within living cells and between cells,Karp (2009), p. 2. in turn relating greatly to the understanding of tissues and organs, as well as organism structure and function.Miller (2012). p. 62. Biochemistry is closely related to molecular biology, which is the study of the molecular mechanisms of biological phenomena.As ...
