Engineered diffusers are refractive, achromatic optical elements with the capability to not only spread and homogenize an input beam but also shape the distribution of energy as well as intensity profiles. Bandlimited illumination is of particular interest for many applications that require certain intensity profiles over specific angular range with maximum efficiency. Here, we describe the concept and design of engineered diffusers as well as the method to fabricate them, from the initial resist master to volume production. Engineered diffusers are found to provide nearly ideal bandlimited illumination without image artifacts and with acceptable manufacturing tolerances. Copyright © 2012 THOSS Media and De Gruyter.

Some of the common diffuser technologies are reviewed in context of performance associated with the technology and its precision in comparison with the band-limited ideal. Recent advancements in microlens diffusers engineered to attain nearly band-limited performance are also discussed. Refractive diffusers are fundamentally free of the intrinsic losses associated with high-order diffraction and zero order, and are best candidates for band-limited behavior. Microlens-based engineered diffusers provide homogenization and general shaping capabilities, while band-limited engineered diffusers have a much improved intensity profile in terms of super-Lorentzian behavior over the entire range of angles. The careful randomization of the diffuser surface structure also creates a scatter distribution that is devoid of artifacts. Source

This paper represents fatigue crack growth life prediction in thin-walled structures (plates or shells). There are two analysis results from two different packages of software: NASGRO and FRANC 3D. They are based on Finite Element Method and Linear Elastic Fracture Mechanics principles (LEMF). Moreover, load interaction to crack growth is analyzed. FRANC 3D software is used to compute and display stress-displacement state of structure and simulation of crack fronts progression. Entire work comprises structural integrity assessment. Source

Treatment grounded in recovery principles is often viewed as not being based on the "medical model." In this Open Forum the author asserts that recovery from mental illness is entirely compatible with concepts of recovery from medical illness and with new approaches to medical treatment. Three ways of conceptualizing recovery are defined: clinical recovery, illness management, and personal recovery. Basing treatment on recovery principles is supported by research that has shown significant remission rates over time among persons with schizophrenia. The author uses examples of public figures and of one family with physical disabilities to illustrate the progress society has made toward accepting and including people with physical illness and disability. Recovery-oriented mental health treatment parallels the move in other medical specialties toward personcentered care. A clinical approach to promote recovery is discussed. Source

Rivers People’s Congress, RPC, an umbrella body of all ethnic, social and non governmental organisations in Rivers State has raised the alarm that there are clandestine efforts by Governor Nyesom Wike’s government  to rubbish the legacies of former state governor Chibuike Amaechi and hang on him a picture of corruption in order to destroy his image. The Co-ordinator of the Congress, Ipinabo Chinda in a statement made available to Vanguard said it was not averse to probing the eight-year rule of the former governor, adding that information at its disposal showed that some persons in government were dubiously collecting and fabricating documents to push out to the media with the intent of presenting the former governor in bad light. “We, members of the Rivers People’s Congress, RPC, an umbrella organ of all ethnic, social and non governmental organizations in Rivers state, are alarmed at the information at our disposal which shows that there is concerted, on-going plot in the government of Chief Wike to rubbish the legacies of our former governor, Rt Hon Chibuike Amaechi, and to hang on him a corruption toga to make him ineligible for any future appointment by the Change touting government of President Muhammadau Buhari. The people of Rivers state will not accept this ungodly move and will definitely stand together and say NO to it. “Indeed we are aware that some persons in government are dubiously collecting and fabricating documents to push out in the social media, in some international media and indeed in some  collaborating news media in Nigeria, that the Amaechi government, in which Chief Nyesom Wike played a very major role until they fell apart, and the person of Rotimi Amaechi, is corrupt. This is with the intent of colouring the public mind with a negative image of Rotimi Amaechi. We abhor this  in all its ramifications. Chinda further charged the Commission of inquiry set up by the current government to probe the two tenures of the previous government instead of the single four year term it was set to probe. It disclosed that the current massive restiveness in the state might lead to implosion if the government failed to thread the path of truth. “We are bold to say that until a properly constituted body finds empirical cause to indict the person of our former governor Rotimi Amaechi, no one should descend to the cesspit of witch hunting, in an attempt to score cheap political victories. “Already, there is massive restiveness which can easily lead to implosion in the state, if the Wike government does not thread softly the part of truth. We caution the Wike government to avoid this road to odium and toe the part of fairness, justice and truth,” the statement said.
