Gonadectomy
Castration is any action, surgical, chemical, or otherwise, by which an individual loses use of the testicles: the male gonad. Surgical castration is bilateral orchiectomy (excision of both testicles), while chemical castration uses pharmaceutical drugs to deactivate the testes. Castration causes sterilization (preventing the castrated person or animal from reproducing); it also greatly reduces the production of hormones, such as testosterone and estrogen. Surgical castration in animals is often called neutering. The term ''castration'' is sometimes also used to refer to the removal of the ovaries in the female, otherwise known as an oophorectomy, or the removal of internal testes, otherwise known as gonadectomy. The equivalent of castration for female animals is spaying. Estrogen levels drop following oophorectomy, and long-term effects of the reduction of sex hormones are significant throughout the body. Castration of animals is intended to favor a desired development of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spaying
Neutering, from the Latin ''neuter'' ('of neither sex'), is the removal of an animal's reproductive organ, either all of it or a considerably large part. The male-specific term is castration, while spaying is usually reserved for female animals. Colloquially, both terms are often referred to as fixing. In male horses, castrating is referred to as ''gelding''. An animal that has not been neutered is sometimes referred to as ''entire'' or ''intact''. Neutering is the most common method for animal sterilization. Humane societies, animal shelters, and rescue groups urge pet owners to have their pets neutered to prevent the births of unwanted litters, which contribute to the overpopulation of unwanted animals in the rescue system. Many countries require that all adopted cats and dogs be sterilized before going to their new homes. Methods of sterilization Females (spaying) Spaying is the surgical removal of the ovaries and uterus in female animals. It is commonly performed as a ...

Estrogen
Estrogen or oestrogen is a category of sex hormone responsible for the development and regulation of the female reproductive system and secondary sex characteristics. There are three major endogenous estrogens that have estrogenic hormonal activity: estrone (E1), estradiol (E2), and estriol (E3). Estradiol, an estrane, is the most potent and prevalent. Another estrogen called estetrol (E4) is produced only during pregnancy. Estrogens are synthesized in all vertebrates and some insects. Their presence in both vertebrates and insects suggests that estrogenic sex hormones have an ancient evolutionary history. Quantitatively, estrogens circulate at lower levels than androgens in both men and women. While estrogen levels are significantly lower in males than in females, estrogens nevertheless have important physiological roles in males. Like all steroid hormones, estrogens readily diffuse across the cell membrane. Once inside the cell, they bind to and activate estrogen receptors (E ...

History Of China
The earliest known written records of the history of China date from as early as 1250 BC, from the Shang dynasty (c. 1600–1046 BC), during the reign of king Wu Ding. Ancient historical texts such as the '' Book of Documents'' (early chapters, 11th century BC), the '' Bamboo Annals'' (c. 296 BC) and the ''Records of the Grand Historian'' (c. 91 BC) describe a Xia dynasty before the Shang, but no writing is known from the period, and Shang writings do not indicate the existence of the Xia. The Shang ruled in the Yellow River valley, which is commonly held to be the cradle of Chinese civilization. However, Neolithic civilizations originated at various cultural centers along both the Yellow River and Yangtze River. These Yellow River and Yangtze civilizations arose millennia before the Shang. With thousands of years of continuous history, China is among the world's oldest civilizations and is regarded as one of the cradles of civilization. The Zhou dynasty (1046–256 BC) supp ...

Sacrifice
Sacrifice is the offering of material possessions or the lives of animals or humans to a deity as an act of propitiation or worship. Evidence of ritual animal sacrifice has been seen at least since ancient Hebrews and Greeks, and possibly existed before that. Evidence of ritual human sacrifice can also be found back to at least pre-Columbian civilizations of Mesoamerica as well as in European civilizations. Varieties of ritual non-human sacrifices are practiced by numerous religions today. Terminology The Latin term ''sacrificium'' (a sacrifice) derived from Latin ''sacrificus'' (performing priestly functions or sacrifices), which combined the concepts ''sacra'' (sacred things) and ''facere'' (to do or perform). The Latin word ''sacrificium'' came to apply to the Christian eucharist in particular, sometimes named a "bloodless sacrifice" to distinguish it from blood sacrifices. In individual non-Christian ethnic religions, terms translated as "sacrifice" include the Indic ' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Holiness Code
The Holiness code is used in biblical criticism to refer to Leviticus chapters 17–26, and sometimes passages in other books of the Pentateuch, especially Numbers and Exodus. It is so called due to its highly repeated use of the word ''holy'' ( '' qəḏōš'' or ''kadash''). ''Kadash'' is usually translated as "holy", but originally meant "set apart", with "special", "clean/pure", "whole" and "perfect" as associated meanings. The term ''Holiness Code'' was first coined as the ''Heiligkeitsgesetz'' (literally "Holiness Law"; the word 'code' therefore means criminal code) by German theologian August Klostermann in 1877. Critical biblical scholars have regarded it as a distinct unit and have noted that the style is noticeably different from the main body of Leviticus. Unlike the remainder of Leviticus, the many laws of the Holiness Code are expressed very closely packed together, and very briefly. According to most versions of the documentary hypothesis, the Holiness Code repre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Judaism
Judaism ( he, ''Yahăḏūṯ'') is an Abrahamic, monotheistic, and ethnic religion comprising the collective religious, cultural, and legal tradition and civilization of the Jewish people. It has its roots as an organized religion in the Middle East during the Bronze Age. Modern Judaism evolved from Yahwism, the religion of ancient Israel and Judah, by the late 6th century BCE, and is thus considered to be one of the oldest monotheistic religions. Judaism is considered by religious Jews to be the expression of the covenant that God established with the Israelites, their ancestors. It encompasses a wide body of texts, practices, theological positions, and forms of organization. The Torah, as it is commonly understood by Jews, is part of the larger text known as the ''Tanakh''. The ''Tanakh'' is also known to secular scholars of religion as the Hebrew Bible, and to Christians as the " Old Testament". The Torah's supplemental oral tradition is represented by later texts s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Harem
Harem (Persian: حرمسرا ''haramsarā'', ar, حَرِيمٌ ''ḥarīm'', "a sacred inviolable place; harem; female members of the family") refers to domestic spaces that are reserved for the women of the house in a Muslim family. A harem may house a man's wife or wives, their pre-pubescent male children, unmarried daughters, female domestic servants, and other unmarried female relatives. In harems of the past, slave concubines were also housed in the harem. In former times some harems were guarded by eunuchs who were allowed inside. The structure of the harem and the extent of monogamy or polygamy has varied depending on the family's personalities, socio-economic status, and local customs. Similar institutions have been common in other Mediterranean and Middle Eastern civilizations, especially among royal and upper-class families, and the term is sometimes used in other contexts. In traditional Persian residential architecture the women's quarters were known as ''andar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bureaucracy
The term bureaucracy () refers to a body of non-elected governing officials as well as to an administrative policy-making group. Historically, a bureaucracy was a government administration managed by departments staffed with non-elected officials. Today, bureaucracy is the administrative system governing any large institution, whether publicly owned or privately owned. The public administration in many jurisdictions and sub-jurisdictions exemplifies bureaucracy, but so does any centralized hierarchical structure of an institution, e.g. hospitals, academic entities, business firms, professional societies, social clubs, etc. There are two key dilemmas in bureaucracy. The first dilemma revolves around whether bureaucrats should be autonomous or directly accountable to their political masters. The second dilemma revolves around bureaucrats' behavior strictly following the law or whether they have leeway to determine appropriate solutions for varied circumstances. Various commen ...

Eunuch
A eunuch ( ) is a male who has been castrated. Throughout history, castration often served a specific social function. The earliest records for intentional castration to produce eunuchs are from the Sumerian city of Lagash in the 2nd millennium BCE. Over the millennia since, they have performed a wide variety of functions in many different cultures: courtiers or equivalent domestics, for espionage or clandestine operations, castrato singers, concubines, or sexual partners, religious specialists, soldiers, royal guards, government officials, and guardians of women or harem servants. Eunuchs would usually be servants or slaves who had been castrated to make them less threatening servants of a royal court where physical access to the ruler could wield great influence. Seemingly lowly domestic functions—such as making the ruler's bed, bathing him, cutting his hair, carrying him in his litter, or even relaying messages—could, in theory, give a eunuch "the ruler's ear" and impa ...

The Mutilation Of Uranus By Saturn
''The'' () is a grammatical article in English, denoting persons or things already mentioned, under discussion, implied or otherwise presumed familiar to listeners, readers, or speakers. It is the definite article in English. ''The'' is the most frequently used word in the English language; studies and analyses of texts have found it to account for seven percent of all printed English-language words. It is derived from gendered articles in Old English which combined in Middle English and now has a single form used with pronouns of any gender. The word can be used with both singular and plural nouns, and with a noun that starts with any letter. This is different from many other languages, which have different forms of the definite article for different genders or numbers. Pronunciation In most dialects, "the" is pronounced as (with the voiced dental fricative followed by a schwa) when followed by a consonant sound, and as (homophone of pronoun ''thee'') when followed by a v ...
