Jackson, Ambassador/Permanent Representative of The Bahamas to the United Nations, Geneva, on Tuesday, June 13, 2017, delivered the historic, inaugural statement of the Caribbean Community (CARICOM) in the Human Rights Council since that body’s establishment in 2006.At the initiative of the delegation of The Bahamas, the statement was drafted and delivered during the Annual Full Day Discussion on the Human Rights of Women, during a panel discussion convened under the theme of “Accelerating efforts to eliminate violence against women; engaging men and boys in preventing and responding to violence against women and girls.”The Bahamas, the endorsed CARICOM candidate for election to the Human Rights Council for the term 2019-2021, presently serves as focal point on human rights matters for the CARICOM Group in Geneva. It is the hope that this will be the first of many future statements by the Group in this Forum, with a view to ensuring that the voices of CARICOM States are heard on issues of priority for the sub-region.#magneticmedianews Related Items:#magneticmedianews ALERT # 2 ON POTENTIAL TROPICAL CYCLONE NINE ISSUED BY THE BAHAMAS DEPARTMENT OF METEOROLOGY THURSDAY 12TH SEPTEMBER, 2019 AT 9 PM EDT Recommended for you Electricity Cost of Service Study among the big agenda items at September 11 Cabinet meeting The Luxury of Grace Bay in Down Town Provo
KUSI Newsroom, Third suspect arrested in connection with fatal shooting outside La Mesa Burlington Coat Factory Categories: Local San Diego News FacebookTwitter Posted: July 26, 2017 July 26, 2017 KUSI Newsroom TALMADGE (KUSI) — Three suspects were behind bars Wednesday in connection with a robbery that escalated into a fatal shooting outside a Burlington Coat Factory store in La Mesa. Derrick Eli Henderson, 30, Tiesha Miller-Johnson, 32, and Kathryn Luwana Williams, 24, were taken into custody Tuesday in connection with the slaying last week of 30-year-old Travis Lewis in the store’s parking lot in the 7900 block of El Cajon Boulevard, according to police. Henderson was captured following a foot chase and non-injury officer-involved shooting, La Mesa police Lt. Chad Bell said. Lewis was gunned down about 6:45 p.m. Thursday during a confrontation with a man and woman outside the clothing and home-furnishings store near Interstate 8 and Baltimore Drive. He died at the scene. Detectives arrested Miller-Johnson and Williams about noon Tuesday, Bell said.Roughly five hours later, a La Mesa police officer searching for Henderson — the suspected shooter in the homicide — spotted him walking on Altadena Avenue in the City Heights area of San Diego, confronted him and ordered him to get down on the ground. Instead, Henderson bolted, and the detective gave chase and opened fire during a confrontation a short distance away. The unharmed suspect continued running but was soon taken into custody by other officers. It was unclear if Henderson had been armed. San Diego police were investigating the circumstances of the officer-involved shooting. Authorities did not disclose what led them to identify the suspects in the case, all three of whom were booked into county jail on suspicion of first-degree murder.
Calculated deformed cell and displacement under uniaxial loading. The arrows aid the discussion of the mechanism: 1. The arms connecting the corners with the rings move downward. 2. This motion leads to a rotation of the rings. 3. This rotation exerts forces onto the corners in the plane normal to the pushing axis, resulting in an overall twist of the unit cell around this axis.

DOI: 10.1126/science.aao4640AbstractRationally designed artificial materials enable mechanical properties that are inaccessible with ordinary materials. Pushing on an ordinary linearly elastic bar can cause it to be deformed in many ways. However, a twist, the counterpart of optical activity in the static case, is strictly zero. The unavailability of this degree of freedom hinders applications in terms of mode conversion and the realization of advanced mechanical designs using coordinate transformations. Here, we aim at realizing microstructured three-dimensional elastic chiral mechanical metamaterials that overcome this limitation. On overall millimeter-sized samples, we measure twists per axial strain exceeding 2°/%. Scaling up the number of unit cells for fixed sample dimensions, the twist is robust due to metamaterial stiffening, indicating a characteristic length scale and bringing the aforementioned applications into reach. Play A video of a sample during measurement. The left part exhibits a bottom view onto the plate in between the left- and right-handed part of the samples. The right part is a side view onto the same sample. Upon pushing onto the sample, one can see a rotation around the pushing axis on the left and a compression along the pushing axis on the right-hand. For illustration, the in plane displacement vectors are depicted in blue and red. Credit: T. Frenzel et al., Science (2017) The researchers found that making the cells smaller and using a larger number of them to create a structure of the same size resulted in an increase in stiffness and a smaller amount of twisting. This, they note, lies in sharp contrast to how materials normally behave under classical continuum mechanics—where there would be no twisting and the degree of stiffness would normally be independent of scale. They note further that a metamaterial with twisting properties could lend itself to a wide variety of optical applications, such as in devices that guide force fields or other types of waves around an obstacle.

In this new effort, the research trio has created a metamaterial that instead twists either right or left.To create such a material, the researchers used numerical modeling to come up with a cubic form for a cell unit—when such units were configured together, the team found, they would twist when a force was applied. To test their model, the team printed out an actual structure using a 3-D laser. Each cell, the team notes, was made with rings in its faces that led to a rotational effect, with the corners of the cell pulling back around them. Testing showed that the metamaterial could deform at a rate of more than 2 percent per percentage of shortening. ‘Bigger is different’—the unusual physics of mechanical metamaterials exposed PausePlay% buffered00:0000:00UnmuteMuteDisable captionsEnable captionsSettingsCaptionsDisabledQuality0SpeedNormalCaptionsGo back to previous menuQualityGo back to previous menuSpeedGo back to previous menu0.5×0.75×Normal1.25×1.5×1.75×2×Exit fullscreenEnter fullscreen © 2017 Tech Xplore (Phys.org)—A trio of researchers with Karlsruhe Institute of Technology in Germany and Université de Bourgogne Franche-Comté in France has developed a metamaterial that twists either to the right or the left in response to a straight, solid push. In their paper published in the journal Science, Tobias Frenzel, Muamer Kadic, and Martin Wegener describe how they came up with the metamaterial and offer some ideas on the ways it might be put to use.
