Non-Cyanide Silver as a Substitute for Cyanide Processes

Since the mid 1800s, silver has been deposited from a cyanide-based formulation on a commercial basis. Commercial non-cyanide silver plating solutions were first made generally available in the late 1970s, and yet today the vast majority, and nearly all commercial silver plating is conducted in formulations that contain cyanide. This study was conducted to determine if non-cyanide silver plating processes that have been developed in the last few years would be suitable replacements for cyanide based formulations.published or submitted for publicatio

Effect of Barrel Design on Dragout Rate

New barrels for electroplating have been developed and manufacturers of some of these newer designs have claimed significant improvements in drag-out losses by their new barrels. Since water consumption and waste generation are directly tied to dragout rate from processing solutions, it is clear that there is a need to produce a method of evaluating such barrels, so that the user minimizes pollution. This study, funded by The Illinois Waste Management Research Center (WMRC) produced a benchmark test to compare drag-out rates of plating barrels. The study used this test to compare two size ranges of plating barrels, small and large. For small barrels (6??? x 12???), testing showed that a reduction in dragout rate, as high as 48%, may be achieved. For large barrels (16??? x 36???), testing showed that a reduction as high as 44% may be obtained. A survey was conducted to determine the relative durability of the barrels under study. The survey indicated that some of the barrels that produce lower levels of dragout (those using fine mesh) may unfortunately provide less service life, but other low dragout rate barrels offered service life that is similar to traditional barrels.published or submitted for publicatio

Long-term storage of table grape cultivars and the use of liquid-S02 and solid -in-package-S02 generators

Danugue, Waltham Cross, Alphonse Lavallee and Sultanina cvs. of tablegrapes were kept for several weeks in cold storage. To control rots, liquid- orsolid-SO2 generators were used. The appropriate method of SO2 application has tobe chosen according to the cultivar. Of the cvs. examined, Alphonse Lavallee wasthe most suitable for long-term storage. Sultanina had a more restricted storageperiod because of its susceptibility to decay and SO2 injury, Waltham Cross sufferedfrom berry browning, and Danugue from split berries.Langfristige Lagerung von Tafeltraubensorten unter Verwendung von Flüssig- undFest-S02-SpendernTafeltrauben der Sorten Danugue, Waltham Cross, Alphonse Lavellee und Sultanina wurden mehrere Wochen lang kühl gelagert. Um Fäulnisvorgänge zu unterbinden, wurden den Kartons SO2-Spender auf flüssiger oder fester Basis beigepackt. Die Methode der SO2-Anwendung -muß der jeweiligen Traubensorte angepaßt werden. Von den geprüften Sorten eignete sich Alphonse Lavallee am besten für die langfristige Lagerung. Sultanina war wegen ihrer Anfälligkeit gegen Fäulnis und Schädigung durch SO2 nur beschränkt lagerungsfähig. Bei Waltham Cross traten in größerem Umfang gebräunte, bei Danugue geplatzte Beeren auf

Faktor Kesulitan Guru Dalam Melaksanakan Pembelajaran Pendidikan Jasmani Adaptif SLB di Kulon Progo

Penelitian ini bertujuan untuk mengetahui faktor kesulitan yang dialami guru dalam pelaksanaan pembelajaran pendidikan jasmani adaptif. Penelitian ini menggunakan metode deskriptif kualitatif. Dengan menggunakan 3 jenis uji keabsahan data, triangulasi sumber, teknik dan waktu. Pengumpulan data menggunakan teknik survei menggunakan angket melalui wawancara. Populasi dalam penelitian ini yaitu 3 orang guru Sekolah Luar Biasa (SLB) di Kulon Progo.Variabel dalam penelitian ini adalah faktor kesulitan guru dalam melaksanakan pembelajaran penjas adaptif (SLB) di Kulon Progo. Instrumen dalam penelitian ini adalah kuesioner dengan 53 butir pertanyaan yang terbagi kedalam 4 faktor. Teknik analisis data menggunakan deskriptif kualitatif. Dari hasil penelitian yang diperoleh, terdapat 4 faktor yang menyulitkan guru dalam melaksanakan pembelajaran pendidikan jasmani adaptif. Faktor yang pertama berasal dari guru, yang terbagi menjadi tingkat pendidikan guru, penguasaan materi, penggunaan media dan kreatifitas guru. Kesulitan yang kedua yang dialami guru yaitu faktor dari siswa, yang terdiri dari motivasi siswa, kondisi siswa, dan sikap/perilaku siswa. Kesulitan yang ketiga datang dari faktor keterbatasan sarana dan prasarana. Dan kesulitan yang terakhir yaitu faktor kurikulum. Guru tidak membuat rancangan pelaksanaan pembelajaran yang berdampak pada ketidaksesuaian materi pembelajaran dengan kurikulum yang ada

Decree 546 and Female Imprisonment in Colombia: Considering the Impact of Empty Policy on Institutional Trust

What happens to institutional trust when fundamental human rights are not respected by the laws meant to protect them? The social and political environment spurred by the Covid 19 pandemic proved difficult for policymakers and the public alike, but perhaps those with the least agency fared the worst, prisoners. This thesis theorizes the concept of loss of institutional trust as a consequence of “empty policies”, through a feminist constructivist grounded theory study of Decree 546 and its effect on female detainees in Colombia. Intended as a decarceration measure to reduce the rate of Covid-19 transmission among inmates as a means of protecting the rights and health of detainees, few were eligible for release under the law due to a lengthy list of exclusions. The exclusion of drug-related offences had disproportionate impacts on female detainees, whose demographic makeup represents one of the most vulnerable groups in Colombian society both inside and outside the carceral system. An exploration and analysis of Decree 546 and responses to it, underpin the theoretical assumptions made in this thesis, where then, parallels are drawn to the wider context of the Colombian government’s responses to issues facing the country’s most vulnerable groups

Yiddish Metal as a Manifestation of Postvernacularity

This chapter investigates Yiddish-language heavy metal music as a manifes- tation of postvernacularity. Yiddish, the traditional language of Ashkenazic Jews, is now endangered with a geographically dispersed speaker base and a low rate of transmission to younger generations outside of strictly Ortho- dox communities. However, as the heritage language of most Ashkenazic Jews, Yiddish continues to play an important symbolic role in contempo- rary Jewish life even among those who do not speak or understand it. This phenomenon has been termed ‘postvernacularity’ (Shandler, 2006). Yiddish is associated with a rich tradition of folk songs, popular songs, and ballads. Recent decades have seen a growing interest among younger generations in Yiddish language and culture, including its musical tradi- tion. In addition to musicians specialising in traditional Yiddish song, there are also currently two bands worldwide who have produced a metal album in Yiddish: Gevolt (Israel) and Dibbukim (Sweden). The repertoire of both bands is comprised largely of classic Yiddish songs interpreted in a metal style but retaining the traditional lyrics and melodies. The fact that these metal bands often choose to reinterpret traditional staples rather than composing original Yiddish songs can be seen as a reflec- tion of the predominantly postvernacular status of Yiddish. The language plays an iconic role for band members and audiences. Concurrently, the fu- sion of familiar Yiddish songs with metal style reinterprets a musical tradi- tion often associated with pre-Holocaust Ashkenazic society for the twenty- first century
