Z-Push is an open-source implementation of the ActiveSync protocol, which is used for synchronizing email, contacts, calendars, and tasks between mail servers and mobile devices or email clients. It is primarily designed for use with the Zimbra email server but can also be utilized with other mail systems. Z-Push acts as a bridge between the ActiveSync clients (like mobile phones, tablets, and some email applications) and the backend mail server.

Franz Melde, often referred to in the context of "Melde's experiment," is associated with a classical physics experiment conducted in the 19th century. The experiment demonstrates the principle of resonance and the behavior of standing waves on a stretched string. In the setup, a wire is clamped at both ends and can be set into vibration. By adjusting the tension in the wire or the frequency of the vibrations, one can observe standing waves forming at certain frequencies known as harmonic frequencies.

Georg Wilhelm Muncke was a notable figure in the field of dermatology, particularly known for his contributions to the understanding of skin diseases and conditions in the mid-20th century. He is often referenced in dermatological literature for his work on various skin disorders, although there may also be other contexts or interpretations depending on the specific field of interest.

Heinrich Bürger is a German name that can refer to people, but it is not widely recognized as a specific individual in popular or historical contexts.

Heinrich Rubens, often referred to in the context of scientific achievement, is known for his contributions to the field of physics, specifically in relation to the study of electromagnetic waves and spectroscopy. He is notably recognized for his work on the Rubens tube, a demonstration apparatus that visualizes sound waves by converting them into visible patterns of flame. This device can be used to illustrate the relationship between sound waves and pressure variations in gas.

Wilhelm Hallwachs was a German physicist known for his contributions to the field of electromagnetism and the study of photoelectric effects. He was born on March 4, 1859, and passed away on January 21, 1929. Hallwachs is particularly noted for the discovery of the phenomenon of photoelectric emission, which refers to the emission of electrons from a material when it is exposed to light.

Johann Wilhelm Hittorf (1824–1914) was a German physicist and chemist known for his significant contributions to the study of ion transport and the electrical properties of gases. One of his most notable achievements was the development of the Hittorf method, which he used to study the migration of ions in electrolytes. He also explored cathode rays and made important discoveries regarding the behavior of gases and electric discharges.

Karl Ferdinand Braun (1850–1918) was a German physicist and inventor best known for his pioneering work in the field of telecommunications and electronic technology. He made significant contributions to the development of radio communications and is particularly credited with the invention of the crystal receiver and the development of the cathode-ray tube (CRT), which later became fundamental to television and oscilloscopes.

Max Planck was a German theoretical physicist best known for his role in the development of quantum theory, which revolutionized the understanding of atomic and subatomic processes. He was born on April 23, 1858, and died on October 4, 1947. In 1900, Planck introduced the idea that energy is quantized, proposing that electromagnetic energy could be emitted only in discrete quantities, or "quanta.

Max Wien is a concept from physics, specifically in the field of thermodynamics and statistical mechanics. It is often associated with Max Wien's displacement law, which relates to the thermal radiation emitted by a black body. This law states that the wavelength at which the emission of energy is maximized shifts inversely with the temperature of the black body; as the temperature increases, the peak wavelength decreases.

Otto Lummer (1860–1925) was a German physicist known for his contributions to the fields of optics and photometry. He is particularly recognized for his work on the development of optical instruments and for his investigations into light and its properties. Lummer, along with his associate, made significant strides in the study of spectral lines and the precision of optical measurements.

Peter Theophil Riess might refer to the German mathematician and engineer who is known for his contributions to the fields of mathematics and engineering, particularly in relation to linear algebra and its applications.

Rudolf Kohlrausch (1809–1858) was a German physicist and chemist known for his significant contributions to the fields of electrochemistry and physics. He is perhaps best remembered for his work on the electrical conductivity of electrolytes and for establishing the Kohlrausch law, which describes the relationship between the conductance of a solution and the concentrations of the ions present.

Theodor Wulf is best known as a German physicist who gained recognition for his work in the field of high-altitude physics and for his experiments related to cosmic rays. He is perhaps most famous for his 1912 experiments which demonstrated that radiation intensity changes with altitude, providing early evidence for the existence of cosmic rays. Wulf is also associated with the "Wulf radiation" effect, which refers to the variations in radiation experienced at different altitudes.

Wilhelm Wien refers to the German physicist Wilhelm Wien, who is best known for his contributions to the field of thermodynamics and radiation. He was born on January 13, 1864, and died on August 30, 1928. Wien's most significant work is related to "Wien's displacement law," which describes how the wavelength at which the emission of a black body spectrum is maximized shifts to shorter wavelengths as the temperature increases.

Demetrios Eginitis, also known as Demetrius Eginitis, was a notable figure in Greek history, primarily recognized as a 19th-century political figure. He served as the governor of various regions during the period following Greece's independence from Ottoman rule. His contributions were significant in the development of the modern Greek state. In addition to his political role, Eginitis's legacy includes his involvement in various reforms aimed at modernizing the country and fostering national identity.
