Upaya Meningkatkan Kemampuan Fisik Motorik Kasar Anak Melalui Kegiatan Melambungkan dan Menangkap dengan Berbagai Media Anak Usia Dini di TK Al- Fajar Pekanbaru
Authors: Alim Melvi Lesmana
Published: November 2019

Berdasarkan hasil observasi peneliti dikelompok B TK Al-Fajar Pekanbaru ditemukan bahwa masih banyak anak yang belum mampu melakukan kegiatan melambungkan dan menangkap dengan berbagai media. Peneliti melihat kemampuan anak ternyata yang sudah mampu melambungkan dan menangkap bola hanya 3 anak (25%) yang belum mampu 9 anak (75%) hal ini terjadi karena guru kurang maksimal memberikan contoh kepada anak. Subyek penelitian adalah TK Al-Fajar Pekanbaru khususnya kelompok B yang berjumlah 12 orang anak, terdiri dari 6 anak perempuan dan 6 anak laki-laki, dengan usia anak 5-6 tahun. Waktu pelaksanaan direalisasikan selama 10 hari. Dalam kegiatan pertama masih banyak anak yang perlu bimbingan yaitu 10 anak (83,3%) sedangkan anak yang sudah bisa melakukan kegiatan ada 2 anak (19,7 %). dipertemuan kedua anak yang sudah bisa melakukan 4 anak (33%), dan 8 anak (87%) masih perlu bimbingan. Dipertemuan ketiga anak yang bisa bertambah menjadi 5 anak (42%), anak yang masih memerlukan bimbingan 7 anak (58,3%) .

Esther, the Beautiful Queen
Authors: Bradbury William B.
Published: November 2019

William B. Bradbury (1816–68) is best remembered for his contributions to church music and music education. Among his choral compositions, the oratorio Esther, the Beautiful Queen was one of the most popular works during the latter half of the nineteenth century. The work is a rich smorgasbord of mid-nineteenth-century musical styles. In this oratorio, Bradbury combines serious religious idioms with the melodic formulas associated with popular song, as well as dances and operatic elements. As was typical for many works of the time, Bradbury provided only partially notated accompaniments or no accompaniments at all, and these have been realized using cue-sized notes. Based on the score published by the Mason Brothers in 1856, this is the first modern critical edition of Esther, the Beautiful Queen.
Missa Christi resurgentis
Authors: Biber Heinrich Ignaz Franz von
Published: November 2019

Heinrich Ignaz Franz von Biber (1644–1704), best known today for his instrumental music, held posts at the archiepiscopal courts in Kroměříž (Moravia) and Salzburg and was also an accomplished composer of liturgical music. Of his ten or so settings of the mass, the twenty-two-part Missa Christi resurgentis is his only authenticated concerted mass setting yet to be published for which all parts are extant. This edition, based on the only surviving source now held in the music archives of the archbishop's castle in Kromeríz, makes available for the for the first time a composition which reveals much about Biber's polychoral style and the style of polychoral music performed in late-seventeenth-century Salzburg. It also displays many stylistic similarities with the famous fifty-three-part Missa Salisburgenis—now thought to be by Biber—and is an important source for consolidating the claim for Biber's authorship of that work.
Twelve Violin Concertos, Opus 1
Authors: Tessarini Carlo
Published: November 2019

Carlo Tessarini (ca. 1690–ca. 1767) was one of the leading violinists of the generation after Vivaldi. He held major posts in Venice during the 1720s and later in Urbino, establishing an international reputation by travels to Paris, London, and the Netherlands. His widely disseminated instrumental music shows that he was always at the vanguard of developing styles; these concertos published in Amsterdam in 1724 are imaginative examples of the Venetian solo concerto, highly varied in mood and idiomatic in violin writing. The volume represents the first modern edition of a collection by Tessarini.
Symphonies, Part 1
Authors: Marsh John
Published: November 2019

John Marsh (1752–1828) was perhaps the most prolific English composer of his time. His own catalog of compositions records over 350 works, of which he lists thirty-nine symphonies. Of these, only the nine that Marsh had printed are extant, together with three one-movement finales. Marsh was a lawyer by training and a gentleman of varied interests, and his thirty-seven volumes of journals, now published in an abridged edition by Pendragon Press, are among the most valuable sources of information on life and music in eighteenth-century England. The symphonies here published represent the varied styles that Marsh utilized in writing for the musicians in the cities where he worked. “Although not masterpieces of the highest class, Marsh's symphonies have such charm that their neglect seems inexcusable” (Richard Gorer, Grove, 5th ed.).
Mozart's Haffner and Linz Symphonies
Authors: Hummel Johann Nepomuk
Published: November 2019

During the period 1820–30, the noted pianist, composer, and teacher Johann Nepomuk Hummel (1778–1837) was commissioned by the English entrepreneur J. R. Schultz to transcribe orchestral works by Haydn, Mozart, Beethoven, and others. Hummel scored all of these transcriptions for piano, flute, violin, and cello. The Haffner and Linz arrangements appeared as two of six Mozart symphony arrangements published in London in 1824.

The practice of arranging large-scale works for small ensembles was very popular during the early nineteenth century. Playing transcriptions was an ideal way to learn the newest compositions and also was a favorite mode of home entertainment (and, at times, romantic courtship). The majority of the public experienced orchestral music in their homes through the kind of chamber settings Hummel created.

While many composers were asked to make such arrangements, their efforts met with limited success. Hummel, however, was ideally suited to the task. As a student and close friend of Mozart, and a colleague of both Haydn and Beethoven, Hummel also conducted many symphonies and operas in his capacity as kappelmeister in Weimar. Hummel's contributions to the transcription literature are masterful examples, full of virtuosity and inspiration; they also contain valuable information about the performance practices of the period. Most of all, these transcriptions open a window to the past and allow us to observe an excellent composer viewing his greater contemporaries.
Complete Madrigals, Part 2
Authors: Fontanelli Alfonso
Published: November 2019

Alfonso Fontanelli (1557–1622) was a prominent musician and courtier in the Ferrarese court during its flowering in the last decades of the sixteenth century, where his colleagues included Luzzaschi, Wert, and Monteverdi. He became an important figure in the musical culture of Florence and Rome in the early seventeenth century. Fontanelli is consistently included with the most eminent composers of the time by seventeenth-century musicians (Peri, Del Turco, Monteverdi, da Gagliano and Banchieri in the first decade of the seventeenth century) at least until Marco Scacchi (1649), and repeatedly by modern scholars, at least since Alfred Einstein's pioneering monograph on the madrigal (1949). The present edition makes this exquisite and important music available to modern scholars and performers.

This edition includes Fontanelli's two published madrigal books (1595 and 1604), plus an anonymous manuscript anthology (ca. 1590) attributed to Fontanelli by the edition of this edition. The editor has traced the provenance of authorship of the texts set by Fontanelli, many of which the composer was the first to set. In each volume of this edition a few hitherto unpublished and illuminating settings by other composers will be included in an appendix. Texts, translations, and commentary are provided for each piece.
The Complete Motets 18
Authors: Lasso Orlando di
Published: November 2019

Thirty-one motets first published in printed anthologies or copied into manuscripts between 1570 and 1579 appear in this volume. Le Roy and Ballard working in Paris included over half of them in their collections of Lasso's motets and chansons; the others appear in choirbooks from the Bavarian Hofkapelle and in the 1579 expanded reissue in Nuremberg of Gerlach's Selectissimae cantiones. The proportion of secular texts in this volume is less than in CM 17; most of them are ceremonial or love poetry. Among them is “Anna, mihi dilecta,” a strikingly chromatic piece that might date from a time earlier than its 1579 publication. The religious texts include Lasso's longest motet, a six-voice cantus firmus setting of the sequence “Lauda Sion Salvatorem.” Other motets in the volume call for large ensembles of seven, eight, nine, ten, or twelve voices. The five-voice “Domine Jesu Christe, qui cognoscis” is the motet that won for Lasso the first prize in the initial Puy d'Evreux in 1575.
German in childhood and Latin in adolescence: On the bidialectal nature of lexical access in English
Authors: Hernandez Arturo E , Ronderos Juliana , Bodet Tres , Claussenius-Kalman Hannah , Bunta Ferenc
Published: November 2019

The nature of word etymology, long a topic of interest in linguistics, has been considered to a much lesser extent in the word recognition literature. The present study created a database of overlapping words from the English Lexicon Project (ELP) and a database with age of acquisition (AoA) norms which were categorized as either Germanic or Latin-based. Results revealed that Germanic words were learned earlier than Latin-based words. Germanic words also showed lower reaction times and higher accuracy relative to Latin-based words even when controlling for AoA, word frequency and length. Additionally analyses were conducted using a publicly available database that used crowdsourcing data with native and second language (L2)English speakers. The results with native speakers were similar to those collected with the ELP. However, nonnative speakers showed better accuracy and faster reaction times for Latin-based words compared to Germanic words. The findings support a bidialectal view of English in that Germanic words serve as the base of lexical processing during childhood, whereas Latin-based words fill in the lexical space across adolescence and into early adulthood. Furthermore, L2 speakers appear to acquire English via more advanced Latin-based vocabulary relative to native speakers. These results carry implications for theories of word recognition and the processing of lexical items in populations that come from linguistically diverse backgrounds.

Empowering Health Care Professionals: An Interprofessional Education Model Implementation and Evaluation
Authors: Coviello Jessica Shank
Published: November 2019

In 2016, the Institute of Medicine (IOM) reported medical error as the 3rd leading cause of death in healthcare systems in the United States. Effective communication of patient care needs across healthcare disciplines is critical to ensure patient safety, quality of care, and to improve operational efficiencies in healthcare systems. Ineffective collaboration and communication among healthcare professionals within the procedural areas increases the potential of harm as a patient moves from one healthcare professional to another. Health care systems are thus encouraged to train employees with a focus on interprofessional education (IPE) and collaborative practice. IOM and World Health Organization (WHO) recommend the use of IPE to help improve communication and collaboration. However the current educational structure in many institutions does not include IPE. As such, healthcare professionals work in silos, with little or no collaboration with one another, which may result in service duplication, increased service cost, and poor health outcomes for patients.

The Development of Educational Aspirations and Expectations from Adolescence to Young Adulthood: A Longitudinal Study of Mexican-Origin Youth
Authors: Lawson Katherine M. , Atherton Olivia E. , Ferrer Emilio , Robins Richard
Published: November 2019

Mexican-origin youth are at increased risk for school dropout and low educational attainment. High educational aspirations and expectations provide a potential source of resilience, given that they predict positive educational outcomes. Using data from a large sample of Mexican-origin youth (N=674), we examined the development of educational aspirations (how far would you like to go in school?) and expectations (how far do you actually expect to go?) from seventh grade (Mage=12.8) to two years post-high school (Mage=19.8). Results indicate that Mexican-origin youth enter adolescence with very high aspirations and expectations, and maintain them even after transitioning into young adulthood. Several demographic and cultural factors, including parental education, family income, the cultural value of familism, ethnic identity, and Spanish language use, were associated with higher aspirations and expectations.
An examination of idiographic networks of posttraumatic stress disorder symptoms
Authors: Reeves Jonathan Wendall , Fisher Aaron Jason
Published: November 2019

Although applying network theory to posttraumatic stress disorder (PTSD) has yielded promising insights, the lack of equivalence between inter- and intraindividual variation limits the generalizability of these findings to any one individual with PTSD. Better understanding how PTSD symptoms occur and vary over time within an individual instead requires exploring the idiographic network structure of PTSD. To do so, the present study used an intensive repeated measures design to estimate intraindividual networks of PTSD symptoms on a person-by-person basis. Twenty individuals (N = 20) who met criteria for PTSD completed daily surveys assessing PTSD symptoms four times per day for approximately 30 days. Employing a recently validated method provided by Fisher, Reeves, Lawyer, Medaglia, and Rubel (2017), we then used these data to estimate a contemporaneous and temporal network of PTSD symptoms for each individual on a person-by-person basis. We then calculated centrality metrics to determine the relative importance of each symptom in each idiographic network. Across all contemporaneous networks, negative trauma-related cognitions and emotions tended to most commonly be the most central symptoms. Further, across all temporal networks, (a) negative trauma-related emotions were the most common driver of variation in other symptoms over time and (b) distressing trauma-related dreams and sleep disturbance were the most common downstream consequences of variation in other PTSD symptoms over time. Finally, we also review data from two randomly selected participants to illustrate how this approach could be used to identify maintenance factors of PTSD for each individual and guide individual treatment planning.
Classification of Theory of Mind tasks and their computational models
Authors: Rusch Tessa , Gläscher Jan
Published: November 2019

The ability to from a Theory of Mind (ToM) that is to theorize about others mental states and explain and predict behavior in relation to attributed intentional states, constitutes a hallmark of human cognition. These abilities are multi-faceted and include a variety of different cognitive sub-functions. Here, we focus on decision processes in social contexts and review a number of experimental and computational modeling approaches in this field. We classify experimental accounts and formal computational models with respect to two categories: interactivity and uncertainty. Thereby, we aim at capturing the most relevant variations in ToM-related cognitive sub-functions and highlight the nuances of what broadly is referred to as social decisions processes. Finally, we discuss the most typical neuroimaging findings in light of the categorization results.
Rozwój przepisów prawnych w zakresie bioindykacji środowiskowej a stan jakości wód jeziorowych

Published: November 2019

This article shows the genesis of legal regulations in the range of environmental bioindication in national legislation as a result of the implementation of EU solutions. The most important legal act in EU is the FrameworkWater Directive while the Water Law of 2017 in Poland. The main purposeof these legal acts is to maintain a good status, especially ecological status orpotential of water bodies based on bioindication. Changes in this area contributed to detailing and standardizing of the biological indicators of waters,which allow for a more detailed examination of the status of waters and defning the directions of their protection. The assessment of water quality inWarmian-Mazurian Voivodship indicates that approximately 30% of the lakes studied in 2010–2017, had at least good ecological status or potential. In70% of the lakes, primarily phytoplankton (the most sensitive bioindicator)decided on lowering to below good ecological status/potential. Recently, thefnal assessment of the status (ecological plus chemical) of water bodies hasbeen more rigorous due to chemical status based on exceeded content of priority substances in fsh (i.e. in another important bioindicator)

Ubój rytualny w świetle prawa europejskiego i polskiego

Prawo UE wymaga, by zwierzęta przed ubojem zostały oszołomione (były nieświadome), tak aby śmierć była dla nich bezbolesna. Prawodawstwo UE pozwala na przeprowadzanie tzw. uboju rytualnego (tj. bez ogłuszania) w celach religijnych, ale ostateczna decyzja w tej sprawie należy do poszczególnych państw członkowskich. Istnieją wyjątki od uboju religijnego, sformułowane zwłaszcza dla szechity (żydowskiej metody zabijania zwierząt przeznaczonych na pożywienie, czyli mięso koszerne) i muzułmańskiego halal. Społeczności muzułmańskie i żydowskie, stanowiące w sumie prawie kilka procent ludności Europy, prezentują w tej kwestii podobne podejście filozoficzne. Nie ulega wątpliwości, że korzystanie z tej formy uboju budzi wiele emocji i kontrowersji, głównie ze względów społecznych (etycznych i kulturowych). Celem tego artykułu jest przedstawienie dopuszczalności zastosowania uboju rytualnego na tle obowiązującego stanu prawnego UE, prawa międzynarodowego oraz w świetle prawa polskiego. W szczególności należy również rozważyć, czy przepis art. 4 ust. 4 rozporządzenia Rady (UE) nr 1099/2009 z dnia 24 września 2009 r. w sprawie ochrony zwierząt w czasie uśmiercania, w związku z art. 2(k) stanowi ograniczenie prawa wolności religijnej zagwarantowanej w art. 10 Karty praw podstawowych Unii Europejskiej i polskiej Konstytucji.
Przestępstwa przeciwko środowisku w Polsce i Rosji – problemy prawa, ścigania i dowodzenia
Authors: Solodov Denis
Published: November 2019

Criminal prosecution in the environmental criminal cases is typically associates with numerous challenges. Above all, the imperfection of the construction of legal norms providing for criminal responsibility makes them difficult to prosecute and to proof. Another factor is the specificity of the environment itself. The dynamics of its elements, as well as the dependence of their condition on many, not always transparent, easy to determine factors affects the accuracy of damage assessment and makes it extremely difficult to establish cause-and-effect relationships. The high dependency on expert opinions should be noted as well. There are issues related to the lack of standardized expert’s methodology, commonly accepted scientific guidelines, the credibility of the opinions presented by the private experts in the field. The article discusses current challenges related to the environmental criminal responsibility in Poland and Russia.
Odpowiedzialność administracyjna na obszarach specjalnych o charakterze przyrodniczym. Zagadnienia wybrane
Authors: Stelmasiak Jerzy
Published: November 2019

Administrative responsibility in special areas of natural character must take into account a special legal regime in the form of prohibitions in force ontheir territory. This applies to every entity using the natural environment inthese special areas. In addition, the above prohibitions are introduced inorder to protect, in particular, exceptional natural values and landscape values by means of an appropriate form of nature protection, for example landscapepark or protected landscape area. Therefore, an entity using the natural environment will bear administrative responsibility both if it breaches common prohibitions as well as prohibitions or restrictions related to the creation of an area form of nature protection. This also applies to restrictions in running an economic activity or even prohibiting it when it would threaten the proper functioning of a special area of natural character. In addition,it may also be banned to construct new building facilities in a 100-meter wide strip of land from the banks of rivers or lakes. This means that construction of a building facility in this area is treated as an unauthorized construction, which is subject to a demolition order, i.e. it can not be legalized in any case.

Responsibility of public authorities is a special guarantee of the legality of a democratic state. The right to compensation is provided not only for the Constitution of the Republic of Poland, but also other legal acts of a statutory rank. Every year courts in Poland adjudicate on compensation cases, awarding them in many cases. The costs of errors of public authority are borne by the State Treasury, and they are not small.

In recent decades, the impact of postmodern approaches to history teaching has triggered an extensive worldwide debate that accommodates diverse and contrasting voices. This article examines how the education system of Religious Zionism, one of the most important ideological movements in Israel, copes with this issue. This inquiry, which is based on Peter Seixas’s conceptualization, analyzes the system’s history curriculum, its latest textbooks, and an array of lesson plans. The analysis reveals a complex method of coping with postmodernism, including the adoption of clearly postmodern attitudes at the declarative level and the neutralization of their influence in practice.
Death on repeat
Authors: Scott Jason B.
Published: November 2019

In the past decade, images of fatal police shootings shared on social media have inspired protests against militarised policing policies and re-defined the ways marginalised communities seek justice. This article theorises the repetition of violent images and discusses how social media has become an important tool for localising popular critiques of the law. I provide an ethnographic account of a police shooting in a Brazilian favela (shantytown). I am particularly interested in how residents of the favela interpret law and justice in relationship to contemporaneous movements such as Black Lives Matter. Reflecting Walter Benjamin’s concept of mechanical reproduction, this case study demonstrates an ‘aura’ that is shaped by the social and legal context in which a violent image is produced, consumed and aggregated. This case study suggests the possibility for research examining the ways inclusionary social media platforms are increasingly co-opted by oppressive political institutions.
Introduction
Authors: Hughes Geoffrey
Published: November 2019

This issue’s forum continues a lively discussion of Nigel Rapport’s notion of ‘cosmopolitan politesse’ that was previously featured in these pages in the summer of 2018. Rapport has long proposed this sort of politesse as a ‘form of virtue’ and ‘good manners’ (2018: 93) premised on ‘the ontological reality of human individuality’, which in turn necessitates an ‘interactional code’ according to which we must presume both ‘common humanity’ but also ‘distinct individuality’ to the point where we ‘classif[y] the Other in no more substantive fashion than this’ (92). Given anthropology’s history of intricately taxonomising humans according to various criteria, this is indeed a challenging proposal – all the more so in the context of legal anthropology, where being subject to specific norms and laws is often taken to be constitutive of distinctive subjectivities, sensibilities and survival strategies. In this issue, Don Gardner responds, directing his critical attention towards the notion of personhood undergirding Rapport’s plea for a revitalised Kantian liberalism in an era of resurgent xenophobia and ethnonationalism. In the process, we see two accomplished scholars taking positions within (and consciously outside of) a whole range of classical debates in the Western philosophical cannon with pressing relevance for contemporary legal anthropology, from nature versus nurture to free will versus determinism, individualism versus collectivism and structure versus agency.

Since the supply air conditioning systems operation effect depends on the cooling duration and depth, it is quite justified to estimate it by the value of the specific annual cold production, which is the product of the necessary cooling capacity for cooling the air to the target temperature multiplied by duration of operation at a given cooling capacity and, thus, considers current climatic conditions. Obviously, the realization of the cooling potential (air conditioning) of the ambient air depends on the installed (design) cooling capacity of the air conditioning units, which, in turn, must considering fluctuations in thermal loads by the current variable thermal and humidity parameters of the ambient air. With an increase in the temperature of the ambient air, fuel consumption for the production of a unit capacity (mechanical/electrical energy) increases, and, accordingly, the more harmful substances are removed to the atmosphere with exhaust gases. To reduce the negative impact of unproductive fuel consumption during the operation of air conditioning systems at elevated ambient temperatures, resort to various methods for determining the installed cooling capacity of the installation, to reduce it. In the work, the ecological efficiency of air cooling is studied considering the climatic operating conditions for the Kyiv city that are variable during the year. The annual reduction in emissions of carbon dioxide CO2 and nitric oxide NOX was chosen as indicators for assessing the environmental effect of air cooling. It has been shown that when choosing the installed cooling capacity, by the method of ensuring the maximum growth rate of the annual cold production considering the increase in the installed cooling capacity of the chiller, there is a greater reduction in specific fuel consumption compared to the method of choosing the maximum annual cold production, respectively, and harmful emissions. When comparing the methods for choosing the design cooling capacity, air cooling to 15 °C provides a reduction in carbon dioxide CO2 emissions of more than 34 t for 2017 for the climatic conditions of Kiev, in favor of the method of ensuring the maximum growth rate of annual cold production, and nitric oxide NOX – about 5,8 t.

The subject of the work is the process of creating Earth remote sensing spacecraft (ERS SC) within the framework of solving the problem of obtaining a high-resolution optical system by achieving high temperature dimensional stability (TDS) while retaining the strength of load-bearing structures (LBSs) during SC operation in orbit. The purpose of the work is to substantiate the block diagram of a package of SC strength measures that has been developed and is being implemented at Yuzhnoye SDO in the process of creating ERS SC containing laminar composite materials in their load-bearing structures, in particular using in their LBSs laminar polymer composite materials (PCMs) with special patterns of reinforcing carbon fibers. Objectives of the work: to analyze the use of layered structures with a resulting coefficient of temperature linear elongation close to zero, including negative in the direction of developing a long-term satellite remote sensing; to consider options for compensating for the weakening of the stiffness and strength characteristics of nanocrystals for TRS layered structures, taking into account the properties of PCM, significantly different from the properties of metals and alloys in the direction of increasing the reliability of spacecraft at various stages of development; to evaluate the compensation for the high cost of spacecraft for remote sensing with the duration of the period of active work in orbit based on modern information technologies.The results consist in that the article formulates features of a package of measures directly linked with ensuring the strength, stiffness, durability, and operating life of LBSs in ERS SC. This package of the measures Yuzhnoye SDO has developed and been implementing in the last years has its first priority to attain the TDS of LBSs and covers the whole life cycle of SC: design, manufacture (technology), testing and service. The service includes storage, transportation, prelaunch tests, injection into orbit and operation in orbit. The scientific novelty consists in the fact that the package takes into account all possible technological processes, tests on several versions of mockups and models with maximally full imitation of standard service conditions according to the scheme: onboard equipment ® onboard systems ® SC in whole. Problems are solved using CALS-class information technologies, for the complete realization of which a super computer has been put into operation with a peak speed of 300 teraflops. This enables to continuously improve ERS SC using PCMs for the TDS of LBSs.

The technique of processing the test results to the destruction of samples cut from slings and dome fabric after prolonged use or storage of the parachute is described. The normal law of load distribution before failure is adopted.It is proposed to find the minimum breaking load as the lower confidence limit depending on the number of tested samples and a confidence probability of 0.99.The results of strength tests of samples from the parachutes of the landing D-5 series 2 of 1983, the spare Z-5 of 1984, and the rescue S-5K series 2 of 1989 are presented.A total of 301 samples were tested, including 54 samples from slings D-5, 48 samples from slings Z-5 and S-5K, samples from fabrics of domes on the base and weft. Samples from slings were cut out at the edge of the dome, in the middle, at the arc buckles.Fabric samples were cut radially from the top to the edge of the dome. The dependence of the strength characteristics on the location of the samples along the length of the slings or the dome panel has not been established.There are no gross errors in the tests according to the Grubbs criterion.The strength degradation coefficients of the slings and fabrics of the domes are determined as the ratio of the breaking load after long-term operation or storage to the initial values adopted during the design.The proximity of the degradation coefficients of slings and dome fabrics was noted. Based on the set of test results in order to obtain the minimum values of the degradation coefficients, a linear dependence on the life of the parachute is established.This period should be counted from the year the parachute was made.The dependence of the minimum degradation coefficients (maximum degradation) on the service life makes it possible to assess the drop in the strength characteristics of the structural elements with increasing service life. This dependence allows you to predict the maximum allowable landing speed when deciding on the extension of the life of the parachute.

Published: November 2019

A new image analysis-based instrument has been developed for measurement of low density and high density macrocontaminants from recycled pulp or whitewater. The unit is coupled to a pulp classifier that isolates the contaminants from pulp and concentrates them before their transfer to a specialized chamber that further separates the contaminants based on their relative density to water. The low density contaminants float on the water surface, whereas the high density macrocontaminants sink onto the settling plate, where images of both contaminant types are then captured and analysed. Through image analysis, the high density contaminants are further classified into two categories: contaminants that are whitish in color and mainly comprised of stickies are named heavy stickies, whereas contaminants that are blackish in color and comprised of black toners and dark wood components are named dirt. When operating in the online mode with autosamplers delivering the samples to the pulp classifier, the instrument provides macrocontaminant determinations every 15 min. The total count and surface area of both types of macrocontaminants per kilograms of pulp can then be sent by direct link to the mill data control system, allowing an effective follow-up of macrocontaminant changes in process pulps and waters. The unit also allows the user to view images of the contaminants. The analyzer results obtained in terms of number and area of macrocontaminants show a linear relationship with TAPPI T-277 om-07 “Macro stickies content in pulp: the ‘pick-up’ method.”
Use of talc to control problems associated with dissolved and colloidal material in papermaking

Published: November 2019

Increasingly stringent environmental standards and market demands are forcing pulp and paper mills to minimize both their water usage and their effluent discharge. Higher rates of process water reuse in pulp and paper mills leads to increased amounts of dissolved and colloidal substances in process water, which is a major fac¬tor limiting further closure of the water circuits. This study explores the use of different types of talc as control agents for dissolved and colloidal material contained in white water from paper mills using recovered and coated paper as raw materials. It also identifies the kinds of talc that can be used to control detrimental properties of the white water.
Stoichiometric model of chlorine dioxide delignification of softwood kraft pulps with oxidant-reinforced extraction
Authors: BROGDON BRIAN N.
Published: November 2019

A generalized, steady-state model estimates bleaching delignification and/or chlorine dioxide consumption for sequences that employ oxidant-reinforced extraction. The model is based on Germgård’s stoichiometric expression for the D0E1 sequence, which relates chlorine dioxide uptake to post-extracted kappa number. Germgård’s integrated stoichiometric model was modified to normalize the extracted kappa number to the incoming kappa number. This mathematical transformation allows for various brownstocks and oxygen-delignified pulps with different kappa numbers to be modeled as a single curve whereby its shape is related to the stoichiometric parameter. From analyzing various softwood bleaching studies, it was determined that this stoichiometric parameter could be expressed as a simple function of oxidant-reinforced extraction conditions (e.g., extraction temperature and peroxide dosage). The generalized delignification model forecasts chlorine dioxide usage with small relative error from the experimental values, typically ±3% to ±10%. This model is relatively simple, with a minimum number of equation parameters to determined, and can be used with other steady-state brightening stage models to predict bleach usage.
Assessment of pulp machine white water quality at market kraft pulp mills
Authors: LAPIERRE LUC , BOUCHARD JEAN , BERRY RICHARD
Published: November 2019

The bleaching of pulp is a significant cost, yet the brightness achieved in the bleaching plant can be diminished in the pulp machine because of white water (WW) quality. Monitoring WW quality can control these losses. A method was developed to assess WW quality that allows differentiation between the effect of fibers, fines, and dissolved solids (DS) in the WW. It was found that the quality of the WW varied greatly from mill to mill. The brightness loss was mainly affected by the presence of fines, through a combination of their concentration and color. The DS were significantly less detrimental to the optical properties of the final furnish. None of the constituents present in the pulp machine WW caused significant brightness reversion (except the hardwood fine fractions). It is therefore recommended that a monitoring procedure for WW quality at the mill site be used to diagnose and prevent the occurrence of brightness problems. Such monitoring offers a way to reduce bleaching costs.
Southern pine oxygen delignified pulps produced in a Berty throughflow reactor: How to obtain the highest degree of delignification while maintaining pulp yield and quality
Authors: HEININGEN ADRIAAN VAN , JI YUN
Published: November 2019

The kappa number, intrinsic viscosity, and yield of Southern Pine pulps were determined after oxygen delignification at different alkali concentrations, temperatures, oxygen pressures, and treatment time in a Berty throughflow reactor. It was found that the highest delignification-cellulose degradation selectivity is achieved at low alkali concentrations and temperatures of about 100°C or less. Oxygen pressure has little effect on selectivity. Carbohydrate yield loss is proportional to kappa number loss up to kappa reduction of 60%. At higher delignification, the carbohydrate yield loss increases more strongly than delignification. However, carbohydrate yield loss is linearly correlated with cellulose degradation at all degrees of delignification. Hexenuronic acids are not removed during conventional oxygen delignification. To increase delignification of softwood pulp beyond about 60%, oxygen system design should be changed so that alkali concentration and charge are decoupled, as is similarly done in modern cooking systems.

Published: November 2019

Increasingly stringent environmental standards and the need for sustainable development are forcing pulp and paper mills to study methods to maximize the use of process wastes. Several studies have shown that “hydrothermal process” wastes might serve as raw material to obtain monosaccharides and oligosaccharides. High-performance liquid chromatography (HPLC) traditionally has been used to study these carbohydrates. However, HPLC has a series of disadvantages that could be avoided by use of other methods. This study evaluated the potential use of near infrared spectroscopy (NIRS) as a substitute analysis method for HPLC, using rice straw as raw material. The results showed that NIRS analysis can be used as a prediction method for monosaccharides and oligosaccharides. This method has the additional advantage of being a fast, nondestructive technique that does not require pretreatment of samples, and therefore, decreases the costs and the environmental impact of the analyses process.

Published: November 2019

The MeadWestvaco mill in Evadale, TX, USA, in conjunction with VOW Resources LLC, has constructed and commissioned a green biogas skid-mounted pilot plant to evaluate the potential of various organic waste streams to produce high-quality biogas. It is the fourth plant in the world incorporating this technical approach to biogas production. At initial startup, the plant used cow manure as organic feedstock. To commission the plant for verifying the VOW bioaugmentation process, the transition was made to using brown grease. After the brown grease commissioning trials are completed, the plant will be transitioned to a number of paper mill-generated organic wastes to acquire the design parameters and engineering data that will aid in construction of a full-scale biogas facility.
Effect of black liquor replacement in wheat straw soda-AQ cooking and lignin structure of pulps
Authors: DAI KAI , ZHAI HUAMIN
Published: November 2019

The effects of black liquor replacement cooking (BLRC) on wheat straw soda-anthraquinone (AQ) pulps and their lignin structures were investigated by using different black liquor replacement ratios (BLRR) and alkaline nitrobenzene oxidation and ozonation. The residual AQ, alkali, and dissolved lignin, as well as carbohydrates in the wheat straw black liquor, greatly influence wheat straw soda-AQ cooking. The influence could be controlled by different BLRR. The BLRC with around 60% BLRR resulted in superior delignification selectivity. The residual AQ and dissolved carbohydrates in the black liquor are beneficial to delignification selectivity, while the dissolved and degraded lignin can slow the delignification rate. No obvious differences were found in the lignin condensation and β-O-4 structure degradation by the BLRC at different BLRR compared to control soda-AQ cooking. The BLRC technology has potential application because it reduces chemical charge and chemical recovery load and results in higher yield and quality of pulp.
