Black Paper

Adhemar Gelb showed that if a piece of black paper is suspended in midair and illuminated by a projector, it appears white. However, when a white paper is brought into the projector beam and placed next to or surrounding the black paper, the black paper once again appears black. In the staircase Gelb illusion, a succession of increasingly lighter papers, dark gray, middle gray, light gray, and finally white, is brought into the projector beam. Each time a lighter paper is added it appears white, and this causes the prior paper to darken, due to the highest luminance rule of anchoring. When all five shades are present within the beam, the gamut of perceived values is compressed relative to the actual values. The compression requires the simultaneous juxtaposition of different illumination levels and illustrates the codetermination principle of Kardos.

The effect of different fruit bags on the content of chlorophyll and carotenoids in the fruit peel of Chinhuang mango during normal storage and after-ripening process was studied. The results showed that the content of chlorophyll and carotenoid in the bag was significantly lower than that of the control fruit. The skin color of the white paper bag fruit and the no bagged bag fruit was green during the green ripening process, while the outer yellow inner black paper bag fruit showed a yellow green halo. When ripe, the control fruit is yellowish green and orange red. The white paper bag fruit is greenish orange yellow, and the outside yellow inside black composite paper bag fruit is golden yellow.

Front Stage

The scene is an underground studio or workshop. Incense is burning in a large black kettle hanging from a black tripod at front of stage. A red electric bulb under the kettle is surrounded by sticks of kindling wood. Two large portable blackboards are placed one at each side of front stage. Small table with white paper spread ornamented with black paper figures (circle, trapezoid, triangle, etc.) is concealed behind left blackboard. On the table are the following articles: cardboard cylinder, three ice cream cones filled with sand and having same base and height as cylinder. Two eighteen-inch boxes at right front stage covered with white paper and ornamented with black circles to imitate dice.

Flat Embedding

Flat embeddment of certain specimens for electron microscopy is necessary for three classes of biological materials: namely monolayer cells, tissue sections of paraffin or plastics, as well as cell concentrations, exfoliated cells, and cell smears. The present report concerns a flat-embedding technique which can be applied to all these three classes of materials and which is a modified and improved version of Chang's original methodology.Preparation of coverglasses and microslides. Chemically cleaned coverglasses, 11 × 22 mm or other sizes, are laid in rows on black paper. Ink-mark one coner for identifying the spray-side of the glass for growing cells. Lightly spray with Teflon monomer (Heddy/Contact Inductries, Paterson, NO 07524, U.S.A.) from a pressurized can. Bake the sprayed glasses at 500°F for 45 min on Cover-Glass Ceramic Racks (A. Thomas Co. Philadelphia), for Teflon to polymerize.Monolayer Cells. After sterilization, the Teflon-treated coverglasses, with cells attached, are treated or fixed in situ in Columbia staining dishes (A. Thomas Co., Philadelphia) for subsequent processing.

This article deals with Lord Moyne's policy towards the Zionists. It refutes the claim that Lord Moyne was anti-Zionist in his political orientation and in his activities and shows that his positions did not differ from those of other British senior officials at the time. His attitude toward Jewish immigration to Palestine and toward the establishment of a Jewish Brigade during the Second World War was indeed negative. This was not due to anti-Zionist policy, however, but to British strategy that supported the White Paper of 1939 and moved closer to the Arabs during the War. While serving in the British Cabinet, Lord Moyne displayed apolitically pragmatic approach and remained loyal to Prime Minister Churchill. He therefore supported the establishment of a Jewish Brigade and the establishment of a Jewish state in Palestine in the secret committee that Churchill set up in 1944. Unaware of his new positions, the Zionists assassinated him in November 1944. The murder of Lord Moyne affected Churchill, leading him to reject the establishment of a Jewish state in Palestine.

Stakeholder Acceptance

This study aimed to investigate the conditions in which Bitcoin has developed as a leading cryptocurrency and, according to Nakamoto (2008), could become an instrument for everyday payments around the world. In comparison to other digital payment solutions, Bitcoin is based on a peer-to-peer electronic cash system using “the blockchain”. This innovative technology allows for decentralised storage and movement of currency in a fully anonymous way, introducing advantageous methods for encrypted security and faster transactions (Hagiu & Beach, 2014). Scepticism regards Bitcoin’s foundation, energy consumption and price volatility, however, did not take long to arise (Holthaus, 2017). Ten years from its white paper release, Bitcoin is further supported by the same drivers which could sustain its growth as the future of digital payments (Russo, 2018). In order to investigate the key drivers and feasibility of acceptance, a London based survey was used to understand the desirability of Bitcoin as a day-to-day tool for digital payments. Additionally, this research analysed Bitcoin’s stakeholders and forecast drivers of sustainability for its application to become the future of the payment industry. A space which relies on policies that involve multiple layers of society, governments, regulators and tech-firms, all on a global scale. The findings confirmed how the increasing lack of trust of political and financial institutions, coupled with the increasing cases of data-breaches by tech-firms, encouraged over 70% of respondents to consider more decentralised and anonymous methods for their day-to-day actions; like payments. Policy makers need to cope with societies increasingly separating politically but gathering together digitally (LBS, 2017). For Bitcoin to truly establish itself as a global digital payment solution, key stakeholder acceptance must converge alongside the introduction of more robust regulation.
