Júlio Cesar de Arruda. Júlio Cesar de Arruda (born 9 January 1959) is a general in the Brazilian Army. He has served as chief of the army's Department of Engineering and Construction. He was the commander of the Brazilian Army from 30 December 2022 to 21 January 2023.

Biography 
Arruda was born on 9 January 1959 in Cuiabá. He joined the army in 1975. Two years later, he joined the Academia Militar das Agulhas Negras. In his military career, he served in engineering units in Itajubá, Rio de Janeiro, Cuiabá, and Brasília. As lieutenant colonel, he advised the Institutional Security Bureau of the Presidency of the Republic (2000–01) and commanded the 1st Battalion of Special Forces in Goiânia, in the (2005–06). With the rank of colonel, he was a commander at the  in Salvador and taught at the  in Itajubá, at the , and at the Escola de Comando e Estado-Maior do Exército.

He was also a military observer for the United Nations Angola Verification Mission II and an advisor for the Brazilian Military Cooperation in Paraguay. He also completed a course on counterterrorism at the National Defense University in the United States.

He was also a commander at the Academia Militar das Agulhas Negras in Rio and at the Special Operations Command in Goiânia, and he held a variety of other positions.

Command of the Brazilian army 
Arruda was put in charge of the Brazilian army under Jair Bolsonaro on 30 December 2022, replacing Marco Antônio Freire Gomes. Júlio Cesar de Arruda was appointed in coordination with the transition team of Luiz Inácio Lula da Silva, so that the change of command would take place before Lula's inauguration. He was confirmed to his position by Lula's minister of defense José Múcio Monteiro on 6 January 2023.

2023 Brasília attack 
On 8 January, pro-Bolsonaro rioters attacked federal buildings at the Praça dos Três Poderes in Brasília, many calling on the military to overturn the election results in which Jair Bolsonaro lost to Luiz Inácio Lula da Silva. In the aftermath of the attack, Lula administration officials arrived at the headquarters of the Brazilian Army to detain insurrectionists at a pro-Bolsonaro camp on the lawn adjacent to the army headquarters. The officials were faced tanks and lines of soldiers, and Júlio Cesar de Arruda told Minister of Justice Flávio Dino: "You are not going to arrest people here." Lula administration officials say this gave hundreds of insurrectionists an opportunity to escape and evade arrest.

President Lula blamed the intelligence services of the armed forces and the Brazilian Intelligence Agency for failing to alert him to the possibility of a coup attack. On 18 January, Lula affirmed that " [Everyone who participated in coup activity will be punished. Everyone. No matter what rank, no matter what branch of the military they're in.]"

Lula relieved Arruda of his post as commander of the army on 21 January 2023, replacing him with .

Kitchen appliance lift. A kitchen appliance lift () is a tiltable shelf, particularly suitable for use with heavy or noisy kitchen appliances (such as stand mixers), so that the machine can be easily stored and run under the kitchen counter. When folded, the lift will typically fit inside a cupboard under the countertop, and when expanded the top of the shelf will usually be level with the countertop and cause the cupboard door having to be left open. The lifting mechanism is often spring-assisted so that the user does not have to lift the entire weight of the kitchen appliance.

Width 
Internal cabinet width (for example measured in millimeters) is a factor that can impact which types of kitchen cabinets a lifter will fit in. Some lifters can be used with several widths, while others must have a specific internal cabinet width (for example 500 mm or 600 mm). Some lifters are made to fit the 32 mm cabinetmaking system. Some lifters are mounted at the bottom of cupboards, while others are mounted on its sides. It is not uncommon for mechanisms to be sold without a shelf plate.

Load capacity 
The maximum load of the lifter (for example measured in kilograms) should be higher than the food appliance as well as the ingredients and other things that will load the lifter (for example 15 kg or 30 kg). The mass of stand mixers vary, but generally may lie around 10 to 20 kg, and often at least 14 kg. One manufacturer offers three settings of the spring tension for the lifter to work with machines weighing 0–9 kg, 9–14 kg or 14–27 kg, respectively.

Theradome. Theradome or the Theradome Laser Helmet, is a medical device manufactured by American health technology company Theradome, Inc. The device is a helmet embedded with laser phototherapy technology and is used for hair restoration treatments in men and women.  Its inventor is a former NASA BioMedical Engineer, Tamim Hamid. It was cleared by the FDA in 2013. Theradome has a success rate of 98%.

History 
Theradome was invented by Tamim Hamid and based on research by Hungarian scientist Endre Mester, who noticed that exposure to lasers caused mice to grow hair.

In 2013 Hamid founded Theradome after a successful Indiegogo crowdfunding campaign and released the Theradome Laser Helmet. The device was initially only cleared by the FDA for use by women. It was the first laser helmet to be cleared by the FDA for sale over-the-counter. 

Theradome conducted clinical trials for the use of their device to treat androgenetic alopecia in men from 2015-2016. Though the trial was supposed to report in 2016, no results have been reported.

In 2018, Theradome’s PRO LH80 and EVOLH40 Laser Helmet were cleared by the FDA for use by both men and women.

Cube World (toy). Cube World is a series of electronic toys developed by Radica Games and Mattel between 2005 and 2009. Each Cube World cube contains an animated stick figure who is able to interact with the figures in other cubes when connected together.

Description 

Cube World cubes can be assembled together by magnets on top of one another or side by side. Each cube contains a stick figure that has a unique animation it performs by itself and with others, such as playing a musical instrument or lifting weights. When the cubes are combined, the figures interact with one another, and can move from cube to cube, with up to four at a time in any display across a maximum network of sixteen cubes. The cubes also contain an in-built gyroscope, animating the figures when the cube is tilted upside down. Each cubes also contain unique games played with the buttons, and feature over 100 animations.

Sets 

Cube World was released as 22 different models across six series. Some units in each series were released as a 'Special Edition', in which the cubes were encased in translucent plastic, an example of the clear craze. In Japan, Cube World was distributed by Bandai, which contained identical animations but featured variations to the Radica and Mattel color schemes.

History 

Cube World was initially developed by Conceptioneering Ltd, a company consisting of Crowborough-based inventor and electrical design engineer Tony Ellis and his wife Judie. Ellis was inspired to create the toy based on the design of a block of flats, stating "I started wondering what the people who lived there were up to...we ended up with these cubes with stickmen where you can see what's going on inside these windows." Cube World was initially distributed in 2005 at a retail price of $30 USD for a pair. On October 3, 2006, Mattel acquired Radica Games and incorporated its properties, including Cube World, expanding the brand into a global market. 

Cube World was a commercial success, selling several million units according to Ellis, and received positive reviews from consumer publications.  Michael Fereday of Gadget Speak praised the game as possessing an "interesting fascination beyond their simple graphics," stating "it is amazing what these characters get up (to) either individually or in various combinations." In 2007, Cube World was nominated as the "Electronic Toy of the Year" by Toy Industry Association at the North American International Toy Fair.

SS Wandrahm (1927). Wandrahm was German a cargo ship built in 1927. She was requisitioned by the Kriegsmarine during the Second World War, serving as Schiff 4, V 1801 Wandrahm and V 6114 Eismeer. Post-war, she was allocated to the Soviet Union. Renamed Onega, she was used as a factory ship. She was on the shipping registers until 1969.

Description
As built, the ship was  long, with a beam of  and a depth of . She was powered by a triple expansion steam engine which had cylinders of ,  and  diameter by  stroke. The engine was built by Stettiner Oderwerke, Stettin, Germany. Rated at 120nhp, it drove a single screw propeller, and could propel the ship at .

History
Wandrahm was built in 1927 as yard number 735 by Stettiner Oderwerke for H. M. Gehrckens, Hamburg, Germany. She was launched on 29 November 1927. The Code Letters RGLV were allocated. In 1934, her Code Letters were changed to DHZK.

On 30 September 1939, Wandrahm was requisitioned by the Kriegsmarine. She was designated "Schiff 4" and allocated to 5 Vorpostengruppe. The vorpostengruppe was disbanded on 22 May 1940 and she was reallocated to 18 Vorpostenflotille, serving as V 1801 Wandrahm. On 31 August 1940, she was reallocated to 61 Vorpostenflotille, serving as V 6114 Eismeer.

Eismeer was allocated to the Soviet Union post-war as part of the war reparations. She was renamed Onega (Онега). She was used as a factory ship based in Murmansk. She collected fish from trawlers and processed it before delivery to port. It was found that her hold capacity was too small compared to Liberty ships also used in that role. Therefore, Onega was rebuilt to increase her hold capacity. Following the rebuild, she was assessed at , . Withdrawn from service in 1964, she was mentioned in an accident report in 1965, and was still on the shipping registers in 1969.

Los Angeles abrasion test. The Los Angeles abrasion test (LA abrasion) is the North American standard for testing toughness (resistance to abrasion and degradation) of construction aggregate or gravel and its suitability for road construction. Test methodology and equipment is defined in the ASTM International publications ASTM C131 for  particle sizes smaller than 37 mm (1.5 inches) and ASTM C535 for sizes larger than 19 mm (3/4 of an inch); the overlapping range of 19 to 37 mm can be tested by either of two standards.

The Los Angeles machine defined in the standard is a simple ball mill of specified size and shape The standard charge of rock is set at  depending on the size of the particles. The drum of the mill has a single shelf plate that scoops test samples and steel balls from the bottom, lifts them up and then drops them, creating a crushing impact. The interaction of the drum, steel balls and the samples at the bottom of the drum causes further abrading and grinding. The complete test requires 500 drum revolutions at a speed of 30-33 revolutions per minute. Crushed sample is then separated from fine dust on a sieve, washed, dried and weighed. The test reports loss of mass to abrasion and impact, expressed as a percentage of initial sample mass. Maximum acceptable loss for the base course of the road is 45%; the more demanding surface course must be 35% or less.

The test was developed by the city engineers of Los Angeles in the 1920s. The California Highway Commission found the new methodology superior to the established Deval abrasion test, and adopted the LA test in 1927. In the 1930s, national studies demonstrated the Deval test did not correlate with the service record of sampled rock altogether, while an LA loss rating of less than 40% was a reliable indicator of quality. The federal standard for LA abrasion testing was formally adopted by the ASTM in 1937. Decades later, field studies found that the LA test results do not always correlate with reality, thus engineers outside of the United States developed different national standards like the French wet micro-Deval procedure or the British Standard 812.
