As adults designing playthings intended for children, the Eameses found more inspiration in boxes. The Toy, manufactured by Tigrett Enterprises in 1951, offered children the chance to make their own prefabricated structure, one more colorful and flexible than Carton City. The Eameses had first been in touch with Tigrett about manufacturing large, bright, paper-and-cardboard animal masks based on those they used for skits and photo shoots in the late 1940s. The Memphis-based company was run by the highly entrepreneurial John Burton Tigrett, who made his fortune selling the Glub-Glub duck and may have been looking for more patentable products. The masks never made it out of the prototype stage, but the simpler and more geometric Toy did.

The first version of the Toy made spaces big enough for children to inhabit, like the cartons. The Little Toy, released in 1952, was scaled more like an architectural model, allowing children to radically reinterpret the dollhouse. (The office later prototyped a modern model house for Revell, but it never went into production.) The Little Toy boxes, which feature a grid of colorful rectangles and words, resemble the panelized arrangement of the Eames House façade and the ESUs, and all of these products, at their various scales, were being developed at the Eames Office within the same few years.
In November 2014, Snapchat announced a crackdown on third-party apps of its service and their users. Users of the Windows Phone platform were affected, as Snapchat did not have an official client for it, but numerous third-party apps existed, most popularly one called 6snap. In December, Microsoft was forced to remove 6snap and all other third-party apps of Snapchat from the Windows Phone Store; Snapchat however did not develop an official app for the platform, leaving its users on the platform behind.[186] A petition from users requesting an official Snapchat app reached 43,000 signatures in 2015, but the company still refused to respond and to build an app for Windows Phone.[187] Snapchat was criticized once again later in 2015 when it did not develop an app for Microsoft's Universal Windows Platform (UWP).[188]
NDAA ACTION: The Senate Armed Services Committee next week dives into debate on its version of the National Defense Authorization Act, which will be the upper chamber's first crack at the Pentagon budget.
Miller had Quiet tortured, both as punishment for trying to kill Snake and as interrogation to see if they could get her to crack and talk about the vocal cord parasites. Snake watched as Miller and Ocelot bickered over what to do with her, with Ocelot expressing sympathy for her since he had fallen in love with the legend of Big Boss. Snake agreed with Ocelot, frustrating Miller, and Snake freed Quiet from her restraints.
Unlike Big Boss, however, Venom Snake was far more reserved in his speech and absent of the wit of Big Boss. He rarely cracked jokes or made comments regarding his enemies' tactics. He also lacked Big Boss' outspoken enthusiasm for firearms or food. Most of his reactions were comprised of simple body language rather than words, as he was more of a listener or doer than a speaker. He also had an array of aesthetic differences from Big Boss, such as the shrapnel from the crash embedded in his body, the bionic left arm, and several different fashion choices such as keeping his hair in a ponytail and wearing an eyepatch with two straps rather than one. Venom Snake also preferred to smoke electronic cigars, unlike Big Boss, and was never seen smoking a real cigar.
Due to the memory transfer being incomplete, Venom Snake appeared to suffer from a form of amnesia, as both Miller and Ocelot had to remind him of certain events, such as leading Militaires Sans Frontières with Miller. He also did not possess Big Boss' fluency in Russian, relying instead on the use of translators.[4][5][6] Despite these shortcomings, he did recall the events from the Peace Walker Incident, such as the prototype Battle Gear's similarity to Metal Gear ZEKE giving him déjà vu, and he was able to quote Hot Coldman regarding the ineffectiveness of nuclear deterrence. Ocelot stated that his amnesia might have to do with the shrapnel in his forehead, although the Truth tapes revealed that it was because the memory transfers had to be stopped prematurely due to XOF being set to attack ahead of schedule, as well as the impending arrival of an old foe of Big Boss'.
Avalanche is pushing the boundaries of nuclear fusion while Ultra Safe aims to revolutionize nuclear radioisotope batteries, like those that power Mars rovers. Both companies are expected to deliver functional prototype spacecraft to the Pentagon by 2027.
Today, the state is a hub for commercial nuclear startups, particularly companies trying to crack small-scale nuclear fusion. Unlike fission, which generates energy by breaking down heavy radioactive metals like uranium, fusion occurs when two smaller atomic nuclei collide to form the bigger nucleus of a different element, releasing energy in the process.
The biggest engineering roadblock to fusion is getting the machine to produce more energy than it consumes, but Seattle-based Zap Energy proclaimed last week that it expects to have a working prototype within the year. In 2021, Everett-based Helion Energy announced it would begin building the first commercial nuclear fusion reactor in Everett with a forecast completion date of 2023.
The team is refining the first prototype and plans to scale up to a bigger device in August. The main engineering challenge will be miniaturizing the high-voltage conductor so it fits in the desired package but still supplies enough energy to the cathode so that the ions orbit fast enough to fuse together.
Brittleness due to surface-initiated intergranular attack by oxygen is the major limitation to the application of polycrystalline Ni-based superalloys, particularly in the mid-temperature regime of 600 C to 800 C.[1] Hence, crack initiation and/or growth can be accelerated under either static or fatigue loading situations, and therefore this phenomenon is of significant importance for high-temperature applications.[2] Alloying has been found to play a role in alleviating this effect, presumably because the chemical reactions which are promoted are then altered in subtle ways.[3] However, these are not fully understood since the mechanism responsible for intergranular crack propagation is yet to be established. Whilst this is the case, it seems unlikely that the chemistry of these alloys has yet been optimized.
Recent work has emphasized the formation of a layered oxide structure consisting of different oxide phases growing ahead of an intergranular crack. This suggests that an oxidation reaction is occurring and that it is not oxygen in its elemental form which is embrittling.[4,5,6] Thermodynamically less stable oxides consisting of Ni and Co are found at the beginning and center of the crack while more stable oxides consisting of Ti and Al were found closer to the interface of the oxide and metal.[6] In particular, superalloys containing Nb are considered susceptible to environmentally-assisted cracking due to the formation of Nb-rich oxides such as NbO2 and Nb2O5 at the grain boundary ahead of the crack tip.[7,8] But any interpretation is made very much more complex by the interaction of chemistry, microstructure, processing, and the details of the grain boundary reactions which can arise.[9] In addition, damage tolerance arising from microstructure-dependent crack tip shielding and relaxation has to be considered.[10] There are two points which are of overarching importance if progress is to be made towards improved understanding of this effect and hence its alleviation. First, there is a need for systematic experimentation involving the control of the important compositional and microstructural variables such that the effects of others can be isolated, identified, and confirmed. Second, there is a need to better understand the chemical processes occurring at the grain boundaries at the most appropriate lengthscale and with techniques which are capable of providing the most revealing information. Scanning transmission electron microscopy/energy-dispersive spectroscopy (STEM-EDS) and high-resolution electron back-scatter diffraction (HR-EBSD) are particularly well suited in this regard, and these are used in the present work.
where \(P_\textq\) is the maximum load that the specimen could withstand before quasi-brittle crack propagation occurred, and A is the specimen cross section area. The term Y is a geometry factor, taken from Reference 24 and is given by
where w is the specimen width. The determined conditional fracture toughness, \(K_\textq\), has to be regarded as a geometry-dependent material parameter, due to the amount of crack tip constraint arising due to the miniaturized ETMT tests.
For tests at 700 C, ABD-2 showed the least ductility at 4.2 1 pct whilst ABD-4 showed an increase in ductility to 5.4 0.6 pct. The highest tensile ductility was observed for ABD-6 at 7.8 1.1 pct. This is illustrated in Figure 3(b) together with SEM images of cross sections through failed specimens. The tensile properties obtained for each alloy are summarized in Table II. Thus, tensile ductility in the mid-temperature regime increased as a function of the Nb/Ti ratio (see Figure 4(a)) despite the alloys all having the same yield stress. The observed loss in ductility in the mid-temperature regime is consistent with recent observations made on other superalloy systems[4,26,27,28] and can be explained by the occurrence of intergranular quasi-brittle failure. Crack propagation along the grain boundaries at 700 C also explains the relatively low conditional fracture toughness (see Figure 4(b)). Just like the tensile ductility, toughness increased with increasing Nb/Ti ratio. ABD-2 exhibited the lowest conditional fracture toughness with 19.7 0.5 MPa\(\sqrt\text m\) followed by 21.8 1.2 and 24.6 0.4 MPa\(\sqrt\text m\) for ABD-4 and 6, respectively. This is summarized in Table III together with the maximum applied load \(P_\max\) and the estimate pre-crack length, a, from which the conditional fracture toughness \(K_\textq\) was calculated using Eq. [4]. The pre-crack and sample geometry were maintained between the tests so that comparisons between alloys are valid. 2ff7e9595c
