Fungal Urinary Tract Infection
Fungal urinary tract infections (FUTI) are mainly caused by Candida species. The urine can be an important specimen for the diagnosis of this kind of clinical condition since both the presence of fungi can be identified by urine microscopy and by uroculture and the cells that promotes the immune response against this kind of infectious agent can also be observed. This entry will focus on information related to FUTI and the urinary findings that can be detected during routine urinalysis that can contribute to the identification of this clinical condition.

Shaft Mining
Shaft mining or shaft sinking is excavating a vertical or near-vertical tunnel from the top down, where there is initially no access to the bottom. Shallow shafts, typically sunk for civil engineering projects differ greatly in execution method from deep shafts, typically sunk for mining projects. When the top of the excavation is the ground surface, it is referred to as a shaft; when the top of the excavation is underground, it is called a winze or a sub-shaft. Small shafts may be excavated upwards from within an existing mine as long as there is access at the bottom, in which case they are called Raises. A shaft may be either vertical or inclined (between 45 and 90 degrees to the horizontal), although most modern mine shafts are vertical. If access exists at the bottom of the proposed shaft and ground conditions allow then raise boring may be used to excavate the shaft from the bottom up, such shafts are called borehole shafts. Shaft sinking is one of the most difficult of all development methods: restricted space, gravity, groundwater and specialized procedures make the task quite formidable. Historically mine shaft sinking has been among the most dangerous of all the mining occupations and the preserve of mining contractors called sinkers. Today shaft sinking contractors are concentrated in Canada , Germany and South Africa .

Hook-Up Culture
Hook-up culture refers to a culture built on the approved practice of engaging in hook-ups, or sexual encounters between two or more individuals where it is understood that commitment, relationships, and emotional feelings are not expected outcomes. Defining a hook-up is ambiguous because it can have a variety of meanings ranging from casual Kissing to foreplay and oral sex, or in some cases, it can mean participating in sexual intercourse. Hook-ups typically only last a short time and those involved are typically only interested in experiencing sexual intimacy and pleasure. Not all hook-ups can be classified as "one-night stands", however, since some people believe they can eventually lead to dating or more personal connections. While people have engaged in casual sex for many years, the act of "hooking-up" has become increasingly popular on college and university campuses in the United States over the last decade. Hooking up has become common for many college students, and the practice has replaced more traditional 20th century ideas about dating. Furthermore, social media sites like Facebook or Match, and phone applications like Grindr and Tinder have given users an opportunity to form connections with other people who have similar sexual interests or desires. Studying hook-up culture focuses on its influences on the formation and management of friendships and romantic relationships. The growth of hook-up culture is also shaping gender roles, specifically in regards to sexual behavior. Aside from these aspects of hook-ups, taking part in uncommitted sex can lead to potential negative physical and emotional impacts.

Polarization (Politics)
Template:Globalize/US In politics, polarization (or polarisation) can refer to the divergence of political attitudes to ideological extremes. Almost all discussions of polarization in political science consider polarization in the context of political parties and democratic systems of government. When polarization occurs in a two-party system, like the United States , moderate voices often lose power and influence.
