What is center drill bit | Xmystool.com

 Center drill bits, occasionally known as Slocombe drill bits, are used in metalworking to provide a starting hole for a larger-sized drill bit or to make a conical indentation in the end of a workpiece in which to mount a lathe center.

A center drill is used for drilling a hole on the axis of a shaft to hold it between centers. It was also used to drill center holes on machining centers, but has been replaced by the spot drill (which has a simpler geometry) for this purpose.

HSS Double-Head Center Drill For Industry
Centre drills create an accurate centre hole to locate a live centre. They can also be used for spotting or starting a precise hole, which will also give a chamfer on the hole. For precise centering work on CNC machines. Made from a carbide substrate.

Clinical application of procalcitonin (PCT) in the emergency department

图片
  Infectious diseases are one of the common diseases in the emergency department, and the systemic inflammatory response syndrome caused by infection is the most fundamental pathophysiological change in sepsis. Due to the complexity of the systemic inflammatory response, there are no ideal diagnostic, stratification, prognostic tools, and effective treatment options. A number of studies have demonstrated that the pathophysiology of early sepsis is functional and reversible. Therefore, early and accurate diagnosis and monitoring of sepsis is one of the decisive factors in improving prognosis. Procalcitonin (PCT) has a good association with infection and sepsis and has been recommended for the diagnosis, stratification, treatment monitoring, and prognostic assessment of bacterial sepsis. 1 Introduction to the PCT 1.1 The main biological effects of PCT There is no clear conclusion on the biological effects of PCT, and the main biological effects are: the role of secondary inflamm...

Focus on CRET technology, Learn about the 5th generation of chemiluminescence

图片
  In the first two issues of popular science, the mainstream chemiluminescence technology in immunodiagnosis was introduced, and it was also understood that chemiluminescence is divided into homogeneous chemiluminescence and heterogeneous chemiluminescence according to whether separation and cleaning steps are required. Compared with the traditional heterogeneous immunoassay mode, homogeneous chemiluminescence can further improve the efficiency of clinical detection and simplify the operation steps. Today we focus on the 5th-generation homogeneous chemiluminescence platform developed by Poclight Biotechnology  based on CRET technology. Chemiluminescence - intensification of involution In the field of chemiluminescence, the phenomenon of involution is intensifying, and the industry is facing a dilemma. With the continuous development of technology and the intensification of market competition, enterprises and research institutions are facing tremendous pressure and challenges. ...

 What are the hormones fertility? When do I need to check? When is the right time to check? What's the point of each one? 1. Follicle-stimulating hormone (FSH) It is a glycoprotein hormone secreted by the pituitary gland, and its physiological role is mainly to promote the development and maturation of follicles and secrete estrogen. 2. Luteinizing hormone (LH) It is a glycoprotein hormone secreted by the pituitary gland. The physiological function is mainly to promote female ovulation and luteinization, and promote the secretion of progesterone and estrogen by the corpus luteum. 3. Prolactin (PRL) It is a polypeptide protein hormone secreted by the pituitary gland, and its main function is to promote breast development and lactation. 4. Estradiol (E2) It is mainly secreted by the ovaries and to a lesser extent by the adrenal glands. The main function is to make the endometrium grow into a proliferative phase and promote the development of female secondary sexua...
