Johann Albert Eytelwein. Johann Albert Eytelwein (31 December 1764 – 18 October 1849) was a German engineer who was among the first to examine mechanical problems dealing with friction, pulleys, and hydraulics. 

Eytelwein was born in Frankfurt to Christian Philipp and Anna Elisabeth Katharina née Hung. He joined the Prussian army in 1779 and became a bombardier in the 1st Artillery Regiment later serving under General von Tempelhoff who kindled an interest in engineering. He then trained as a surveyor and in 1790 became an inspector of buildings. His building department published the first German journal of civil engineering, Sammlung nützlicher Aufsätze und Nachrichten, die Baukunst betreffend and in 1799 he was among the founders of the Berlin Bauakademie ("Building Academy"). He received an honorary doctorate from Berlin University in 1811. His major publication was the Handbuch der Mechanik fester Körper und Hydraulik [editions in 1801, 1823, 1842] and the Handbuch der Statik fester Körper [1808, 1832]. In these works he examined pulleys and belts and examined the forces involved, developing on the theory of Euler. The Euler-Eytelwein Formula, also known as the capstan equation was one of the key ideas introduced by him.

CrystalExplorer. CrystalExplorer (CE) is a freeware designed to analysis the crystal structure with *.cif file format.

CE is helpful to investigate different areas of solid-state chemistry such as Hirshfeld surface analysis, intermolecular interactions, polymorphism, effect of pressure and temperature on crystal structure, single-crystal to single-crystal reactions, analyzing the voids present in crystal, and structure-property relationships.

The graphical interface of CE towards the 3D crystal structure visualization aids in drawing the crystal structure with or without Hirshfeld surface.

History
CrystalExplorer launched as a graphical user interface which facilitates the visualization of interactions in molecular crystal structures. In 2006, M. A. Spackman's student Dylan Jayatilaka and coworkers presented a paper about their new crystallographic software in the occasion of 23rd European Crystallographic Meeting (ECM23) conducted in Leuven. This software was designed by School of Biomedical and Chemical Sciences, University of Western Australia, Nedlands 6009, Australia.  From 2006 onward researchers started citing the program in their research papers.

CrystalExplorer 2.1 designed for Mac OS X, Windows and Linux platforms for the analysis of crystal structures and can be used to investigate many areas of solid-state chemistry such as studying intermolecular interactions, polymorphism, the effects of pressure and temperature on crystal structures, single-crystal to single-crystal reactions, analyzing crystal voids, structure-property relationships, isostructural compounds, and calculate intermolecular interaction energies.

Currently in 2020 September, there are more than 2000 research papers that cite CrystalExplorer software as per google scholar analysis.

Licence
CrystalExplorer17 is licensed free-of-charges under conditions, such as not using the free version of CrystalExplorer to conduct commercial or confidential research, or research that is not likely to be published in a peer-reviewed journal.

Slater's Bridge. Slater's Bridge is a traditional packhorse bridge in Little Langdale in the English Lake District, standing at National Grid Reference .

History and construction
The bridge dates back to the 17th century, and became a listed building in 1967. Built of slate, it consists of a  segmental arch and a flatter span built of slabs, and incorporates a natural boulder in midstream. The bridge is thought to have been created by miners working in the nearby Tilberthwaite Fells.

Already in the 19th century, Alexander Craig Gibson called it "an exquisite and unique specimen of a style of bridge all but extinct"; a century later, Alfred Wainwright called it "the most picturesque footbridge in Lakeland, a slender arch constructed of slate from the quarries and built to give the quarrymen a shorter access from their homes".

Literary associations
The bridge was acclaimed in a 20th-century poem as "...this/exercise in hanging circularity, toppling stress./The rough slate wedges carry their own likeness/on the belly of each, with the grass springing sidewise/at the joins. The bare arch links two valley sides/as though by a handclasp across the sky's reflection".

John Price Jackson. John Price Jackson (27 September 1868, in Kennett Square – 2 April 1948) was an American electrical engineer and academic, civil servant and soldier.

John was born into a quaker family in Kennett Square, Pennsylvania. His parents were Josiah and Mary Price Jackson. His elder brother, Dugald C. Jackson, co-wrote some books with him and also had a career as an electrical engineer and academic.

When the Pennsylvania Department of Labor and Industry was founded by Governor John Kinley Tener, Jackson was appointed as the first Commissioner. He was subsequently confirmed in post by Governor Martin Grove Brumbaugh on 2 June 1917, but took a leave of absence from state office when he accepted a Commission in the US Army following the United States entry into the First World War.

Jackson served under Brigadier General Charles Gates Dawes in the office of the Chief Purchasing Agent for the American Expeditionary Forces (AEF). Dawes appointed him in February 1918 to head a labor bureau to coordinate hiring of civilian labor to support the AEF's logistical system in Europe.

Nasser-class ship. Nasser () is a class of auxiliary ships built by Iranian shipyard Arvandan and operated by the Navy of the Islamic Revolutionary Guard Corps.

Type 
Arvandan Shipbuilding Co., the manufacturer of these vessels, is a civilian shipyard that specializes in light passenger ferries. According to Jane's Fighting Ships, the ships in the class are yard auxiliary general (YAG), while the International Institute for Strategic Studies classifies them as transport ship (AP). The U.S. Navy has variously described the class as "auxiliary patrol vessel" or "light personnel transport".

Design

Dimensions and machinery 
The class design is  long, would have a beam of  and a draft of . It uses two shafts coupled with two diesel engines that provide power for a top speed of . Nasser vessels can carry 86 troops or 35 tons of supplies.

Armament
Joseph Trevithick, a fellow at GlobalSecurity.org, says the vessels seem "lightly armed", adding that it "did not necessarily mean it might not have been threatening". Trevithick also opines that they could be used as minelayers. The 2015 edition of Jane's mentions that the ships are equipped with one 12.7mm machine gun, as well as unknown electro-optic systems.

MOJ (motorcycle). MOJ is a defunct brand of motorcycles that were manufactured in Katowice, Poland from 1937 to 1939. The name derives from the nickname of the founder, Gustaw Różycki, whilst he was a student at the University of Leoben.

History
In 1933, mining engineer Gustaw Różycki bought a small mining machinery factory in Załęże, Katowice from Alfred Wagner and renamed it Fabryka Maszyn Oraz Odlewnia Żelaza i Metali MOJ. He set about expanding the company and by the time WWII broke out the number of employees had risen from 15 to 800. The company produced mining equipment, boat engines, chain saws and other machinery.

Różycki was a motorcycle enthusiast and wanted to produce his own machines. In 1935 he employed engineer Karol Zuber to head a new motorcycle division. The first motorcycle, the MOJ 130, was produced later that year. It had a 128 cc two-stroke engine. A 250 cc machine was in development, and there were plans to produce cars. Land had been brought in Sandomierz to build a second factory for car production. Car production was due to start in 1940/1 but the war brought an end to this plan. A rotary engine was in development and Różycki was granted a patent for the design.

Following the German invasion of Poland, the factory was commandeered by the Germans to produce mining equipment and ammunition, although a small number of motorcycles were manufactured for military use. Różycki joined the resistance and as a result spent the rest of the war in concentration camps in Dachau and Gusen.

After the end of WWII, the factory was nationalised and it was decided not to re-establish motorcycle production.

Models

MOJ 130
The motorcycle was modelled on German motorcycles of the time, with an emphasis on quality. Prototype models were fitted with a Villiers engine, but production models used their own 128 cc single cylinder two-stroke engine. A rigid duplex frame was used with pressed steel girder forks. Most components were made by the factory or were from Polish manufacturers. The motorcycle was presented to the press in February 1937 and production machines were available in August of that year.

In 1938 the engine was improved with dual exhausts exiting the cylinder at the rear and the carburettor moved to the side of the engine. The gearchange was  changed from hand to foot operated. Some machines were purchased by the military, including the 10th Motorized Cavalry Brigade. There was also a state-funded purchase scheme for officers to buy the motorcycle.

A few competition versions of the model were made and on which Różycki entered various events, including the 1939 Tatra Rally, which he won.

Around 600 units of the MOJ 130 were produced pre-war.

1990 Lehigh Engineers football team. The 1990 Lehigh Engineers football team was an American football team that represented Lehigh University during the 1990 NCAA Division I-AA football season. Lehigh tied for second place in the newly renamed Patriot League.

In their fifth year under head coach Hank Small, the Engineers compiled a 7–4 record. Craig Domalewski and Jarrod Johnson were the team captains.

The Engineers outscored opponents 329 to 211. Their 3–2 conference record placed Lehigh in a three-way tie for second place in the six-team Patriot League standings. This was the first year of competition under the Patriot League banner; the league had been known as the Colonial League since 1986.

Following two early-season wins, Lehigh briefly entered the national Division I-AA rankings, appearing at No. 20 in the poll released September 18. A loss dropped them out of the top 20 the next week. Lehigh finished the season unranked.

Lehigh played its home games at Goodman Stadium on the university's Goodman Campus in Bethlehem, Pennsylvania.

Eastern Java–Bali rain forests. The Eastern Java-Bali rain forests ecoregion (WWF ID: IM0113) covers the lowland areas of the eastern half of the island of Java, and the island of Bali, in Indonesia. This ecoregion is distinct from the Eastern Java-Bali montane rain forests, which exists at higher elevations where mountain forest habitat dominates. Very little of the natural lowland rainforest remains in its pre-human settlement state.

Location and description 
The ecoregion covers the lowlands of the eastern half of Java and Bali. Also included are Madura Island and the Kangean Islands off the north coast of Java. The soil is mostly volcanic and alluvial deposits due to the large, active volcanoes in the center, and with some uplifted coral limestone.

Climate 
The climate of the ecoregion is Tropical monsoon climate (Köppen climate classification (Am)).  This climate is characterized by relatively even temperatures throughout the year (all months being greater than  average temperature), and a pronounced dry season.  The driest month has less than 60 mm of precipitation, but more than (100-(average/25)) mm.  This climate is mid-way between a tropical rainforest and a tropical savannah.  The dry month usually at or right after the winter solstice in the Southern Hemisphere.

Flora and fauna 
About 25% of the region is closed forest, 25% open forest, 35% cultivated/agricultural, and the rest urban or built up.  Precipitation levels determine much of the forest character.  Through the inland lowlands, the forests are moist deciduous, with 1,500–4,000 mm of precipitation per year and with a four-six months of dry season. Because precipitation levels decline towards the east of Java, these forests are not as wet as in the west.  Typical trees in these moist deciduous forests include Homalium tomentosum, silk trees (Albizia lebbekoides), and reonja (Acacia leucophloea), a 20–30 foot tree with yellow flowers.

Along the southern coast of the ecoregion are semi-evergreen rain forests, with higher precipitation levels and only two-four months of dry season.  Common south coast trees include (Artocarpus elasticus) (of the mulberry family), Yellow mahogany (Epicharis parasitica) and Duku (Lansium parasiticum).  Along the northern coast precipitation levels are dryer (below 1,500 mm/year and with more than six months of dry season), resulting in a dry deciduous forest.

Scientists in the ecoregion have recorded 103 species of mammals, notable 15 species of ecologically important fruit bats that provide pollination. Over 350 species of birds have been recorded.

Protected areas 
Less than 3% of this ecoregion is officially protected. Notable protected areas include:
 West Bali National Park
 Meru Betiri National Park
 Alas Purwo National Park
 Baluran National Park
 Karimunjawa National Park
