What causes PV?
MPD-Support - FAQ's - PVThe cause of PV is unknown but as most patients have a change in a molecule called JAK2 in their blood cells doctors are currently investigating why this happens. The chances of PV being inherited are slim if another member of your family has a blood condition it is important to tell your doctor.
Related QuestionsWhat is PV?
PV FAQ - PhotoVoltaic Frequently Questioned AnswersPV is an acronym which stands for 'photovoltaic', a way of producing electricity from light. More properly, the photovoltaic effect is an aspect of the photoelectric effect, and may be defined as the conversion of electromagnetic radiation to electrical voltage by a material. The photovoltaic material that almost everybody has seen is the silvery amorphous silicon solar cells in solar powered calculators.
Related QuestionsMPD-Support - FAQ's - PVPV is a blood disorder in which the bone marrow increases the red blood cell count. When PV is diagnosed, your doctor must exclude any other causes of a raised red cell count, and may want to confirm the presence of a raised red cell mass (see tests).Related Questions

SunPower - Home Owners - Solar Basics: FAQsPV is short for photovoltaic (photo=light, voltaic=electricity), another term for solar electric power. PV is a semiconductor-based technology used to convert light energy into direct current electricity, without moving parts, noise, fuel, or pollution. The terms "solar cell" and "PV cell" are used interchangeably.Related Questions
faqThe photovoltaic (PV) process converts sunlight, the most abundant energy source on the planet directly into electricity. The equipment required for this process has no moving parts and as a result requires minimal maintenance. In addition, the electricity is generated with no emissions and no noise. A PV cell consists of two or more thin layers of semiconducting material, most commonly silicon.Related Questions
What is the PV Network?
Pemphigus Vulgaris NetworkThe Pemphigus Vulgaris Network is a voluntary, not-for-profit, group started in 1997 to provide information and support for people living with pemphigus and their relatives, friends and carers. We also provide an information resource for doctors and other medical professionals. We are part of the British Association of Dermatologists' patient support group organisation and are members of the Skin Care Campaign, Long-term Conditions Alliance, and All Party Parliamentary Group on Skin.

Foundation for Ichthyosis and Related Skin TypesA: The term "ichthyosis" refers to a group of disorders caused by a genetic defect which may have been spontaneous (due to a mutation of a gene) or passed on through family inheritance. The skin's natural shedding process is slowed or inhibited and, in some forms of ichthyosis, the production of skin cells is too rapid.Related Questions
Vulvodynia: Vulvar Pain Clinics: FAQ's Vestibulitis, Vestibu...The precise cause of Vulvodynia is unknown. Some of the theories on causality include: a viral, fungal or bacterial infection; an allergic response to an environmental irritant; an autoimmune response to the body’s own chemistry; trauma; or the result of pelvic floor muscle instability.

B) What is a PV module?
PV FAQ - PhotoVoltaic Frequently Questioned AnswersA photovoltaic module is typically a group of solar cells assembled in a commercial unit ready for installation in a system. It is the form in which most power systems are purchased. Usually the PV module has a specified power rating and guaranteed lifetime (commonly ~20 years).
Related QuestionsC) What is the history of PV?
PV FAQ - PhotoVoltaic Frequently Questioned AnswersIn 1839, Edmund Becquerel of the famous French physicist family, discovered the photovoltaic effect. The material used was copper oxide in an electrolyte. In 1874, Charles Fritts made the first solar cell from selenium and gold. The efficiency was less than 1%. In 1904, Albert Einstein published his monograph on the photoelectric effect. His theory utilized Max Planck's idea of quanta.

Related QuestionsWhat is Polycythemia Vera (PV)?
MPD Online ResourcePolycythemia vera (PV), or Polycythemia rubra vera, is one of the myeloproliferative disorders (MPD). In this variant, there is uncontrolled production of mature red cells leading to an increase in the red cell mass, resulting in abnormally high hematocrit (Hct) and hemoglobin (Hg). This causes an increase in blood volume and viscosity which can lead to complications involving thrombosis, eg heart attack, strokes, or other clotting or bleeding episodes, if not controlled.
