Computational evidence for kinetically controlled radical coupling during lignification
Authors: Gani Terry , Orella Michael , Anderson Eric , Stone Michael , Brushett Fikile , Beckham Gregg , Román-Leshkov Yuriy
Published: May 2019

Lignin is an alkyl-aromatic biopolymer that, despite its abundance, is underutilized as a renewable feedstock because of its highly complex structure. An approach to overcome this challenge that has gained prominence in recent years leverages the plasticity and malleability of lignin biosynthesis to tune lignin structure in planta through genetic approaches. An improved understanding of lignin biosynthesis can thus provide fundamental insights critical for the development of effective tailoring and valorization strategies. Although it is widely accepted that lignin monomers and growing chains are oxidized enzymatically into radicals that then undergo kinetically-controlled coupling in planta, direct experimental evidence has been scarce because of the difficulty of exactly replicating in planta lignification conditions. Here, we computationally investigate a set of radical reactions representative of lignin biosynthesis. We show that, contrary to the widely held notion that radical coupling reactions should be barrierless and dynamically controlled, the computed activation energies can be qualitatively consistent with key structural observations made empirically for native lignin in a variety of biomass types. We also rationalize the origins of regioselectivity in coupling reactions through structural and activation strain analyses. Our findings lay the groundwork for more detailed multiscale simulations of the lignification process.
Applied Process Simulation-Driven Oil and Gas Separation Plant Optimization using Surrogate Modeling and Evolutionary Algorithms
Authors: Andreasen Anders
Published: May 2019

In this article the optimization of a realistic oil and gas separation plant has been studied. Two different fluids are investigated and compared in terms of the optimization potential. Using Design of Computer Experiment (DACE) via Latin Hypercube Sampling (LHS) and rigorous process simulations, surrogate models using Kriging have been established for selected model responses. The surrogate models are used in combination with a variety of different evolutionary algorithms for optimizing the operating profit, mainly by maximizing the recoverable oil production. A total of 10 variables representing pressure and temperature various key places in the separation plant are optimized to maximize the operational profit. The optimization is bounded in the variables and a constraint function is included to ensure that the optimal solution allows export of oil with an RVP < 12 psia. The main finding is that, while a high pressure is preferred in the first separation stage, apparently a single optimal setting for the pressure in downstream separators does not appear to exist. In the second stage separator apparently two different, yet equally optimal, settings are revealed. In the third and final separation stage a correlation between the separator pressure and the applied inlet temperature exists, where different combinations of pressure and temperature yields equally optimal results.
In-Flow Flash Nanoprecipitation of Size-Controlled D-Leucine Nanoparticles for Spray-Drying Formulations
Authors: Cerra Bruno , Gabriele Mosca , Ricci Maurizio , Schoubben Aurelie , Gioiello Antimo
Published: May 2019

In this work we report the development of a cheap and scalable flow-based flash nanoprecipitation approach to prepare D-leucine nanoparticles particularly useful as glidants in dry powder for inhalation. Starting from preliminary batch screens, the process was successfully optimized and scaled-up under mesofluidic conditions. The nebulization with both mini and nano spray-dryer, the SEM analysis of nanoparticles and the aerodynamic evaluation of a formulation obtained by physical mixing of atomized D-leucine powders with budenoside showed an excellent decrease in particle size without altering the morphology, and a marked improvement in the aerodynamic properties of the drug. This simple and economic method by physical mixing of leucine with micronized active pharmaceutical ingredients can represent a valid alternative to co-spray-drying.
Reducing Radiation Damage in Soft Matter with Femtosecond Timed Single-Electron Packets
Authors: VandenBussche Elisah , Flannigan David
Published: May 2019

We study the effects on radiation damage of using a femtosecond laser-driven, pulsed electron source in an otherwise conventional transmission electron microscope. We demonstrate precise control - at the single electron level - over the emission timing and the number of electrons emitted with each femtosecond laser pulse. We find that radiation damage is significantly reduced for such pulsed beams when compared to conventional ultralow-dose methods for the same dose rate and the same total dose. We also show that the degree of damage can be controlled by carefully varying the time between arrival of each electron at the specimen and by changing the number of electrons in each packet.

The scalable production of homogenous, uniform carbon nanomaterials represents a key synthetic challenge for contemporary organic synthesis as nearly all current fabrication methods provide heterogenous mixtures of various carbonized products. For carbon nanotubes (CNTs) in particular, the inability to access structures with specific diameters or chiralities severely limits their potential applications. Here, we present a general approach to access solid-state CNT mimic structures via the self-assembly of fluorinated nanohoops, which can be synthesized in a scalable, size-selective fashion. X-ray crystallography reveals that these CNT mimics exhibit uniform channel diameters that are precisely defined by the diameter of their nanohoop constituents, which self-assemble in a tubular fashion via a combination of arene-pefluoroarene and C—H---F interactions. The nanotube-like assembly of these systems results in capabilities such as linear guest alignment and permanently accessible channels, both of which are observed in CNTs but not in the analogous all-hydrocarbon nanohoop systems. Calculations suggest that the organofluorine interactions observed in the crystal structure are indeed critical in the self-assembly and robustness of the CNT mimic systems. This work establishes the self-assembly of carbon nanohoops via weak interactions as an attractive means to generate solid-state materials that mimic carbon nanotubes, importantly with the unparalleled tunability enabled by organic synthesis.
Formic Acid Mediated Direct Z-Selective Reductive Coupling of Dienes and Aldehydes
Authors: Cooze Christopher , Dada Raphael , Lundgren Rylan
Published: May 2019

We demonstrate that formic acid mediates the Rh-catalyzed, Z-selective coupling of dienes and aldehydes. The process is distinguished by broad tolerance towards reducible or electrophilic groups. Kinetic analysis suggests that generation of the catalytically active Rh-intermediate by ligand dissociation is the rate determining step. The rapid generation and trapping of Rh-allyl intermediates is key to preventing chain-walking isomerization events that plague related protocols. Insights gained through this study may have wider implications in selective metal-catalyzed hydrofunctionalization reactions.
On the Relative Resonance-Acceptor Abilities of CN, NO, COMe, CHO and NO2 Groups
Authors: Yadav Veejendra , Yadav Arpita
Published: May 2019

The relative resonance-acceptor ability based on ∆G‡out is different from that based on ∆G‡in for the conrotatory ring-opening of 3-carbomethoxycyclobutene bearing CN, NO, COMe, CHO and NO2 as C1-substituent. In contrast, the relative resonance-acceptor ability based on sC3C4-p*C1C2 interaction in TSout is much the same as in TSin. It matches further with the acceptor ability based on the net of sC3C4-p*C1C2 and pC1C2-s*C3C4 interactions. The overall resonance-acceptor ability is estimated to be CN < COMe < CHO < NO2 < NO from calculations at MP2/6-31+G(d,p) level of theory.

Macrocycles of Higher Ortho-Phenylenes: Assembly and Folding
Authors: Kinney Zacharias , Kirinda Viraj , Hartley Scott
Published: May 2019

Higher-order structure in abiotic foldamer systems represents an important but largely unrealized goal. As one approach to this challenge, covalent assembly can be used to assemble macrocycles with foldamer subunits in well-defined spatial relationships. Such systems have previously been shown to exhibit self-sorting, new folding motifs, and dynamic stereoisomerism, yet there remain important questions about the interplay between folding and macrocyclization and the effect of structural confinement on folding behavior. Here, we explore the dynamic covalent assembly of extended ortho-phenylenes (hexamer and decamer) with rod-shaped linkers. Characteristic 1H chemical shift differences between cyclic and acyclic systems can be compared with computational conformer libraries to determine the folding states of the macrocycles. We show that the bite angle provides a measure of the fit of an o-phenylene conformer within a shape-persistent macrocycle, affecting both assembly and ultimate folding behavior. For the o-phenylene hexamer, the bite angle and conformer stability work synergistically to direct assembly toward triangular [3+3] macrocycles of well-folded oligomers. For the decamer, the energetic accessibility of conformers with small bite angles allows [2+2] macrocycles to be formed as the predominant species. In these systems, the o-phenylenes are forced into unusual folding states, preferentially adopting a backbone geometry with distinct helical blocks of opposite handedness. The results show that simple restrictions can be used to direct foldamers toward increasingly complex geometries.
Deep Learning Model for Predicting Solvation Free Energies in Generic Organic Solvents
Authors: Lim Hyuntae , Jung Younjoon
Published: May 2019

Prediction of aqueous solubilities or hydration free energies is an extensively studied area in machine learning applications on chemistry since water is the sole solvent in the living system. However, for non-aqueous solutions, few machine learning studies have been undertaken so far despite the fact that the solvation mechanism plays an important role in various chemical reactions. Here, we introduce a novel, machine-learning based quantitative structure-property prediction method which predicts solvation free energies for various organic solute and solvent systems.

A novelty of our method involves two separate solvent and solute encoder networks that can quantify structural features of given compounds via word embedding and recurrent layers, with the attention mechanism which extracts important substructures from outputs of recurrent neural networks. As a result, the predictor network calculates solvation free energy of a given mixture using features from encoders. With results obtained from extensive calculations on 2495 solute-solvent mixtures, we demonstrate that our methodology outperforms both ab initio and MD solvation model in terms of estimation error for solvation energy.

Remembering Resistance
Authors: Shawcross Jared
Published: May 2019

The Nazi occupation of Europe saw the emergence of various forms of resistance with varying degrees of success across the continent over the course of World War II. These acts of resistance have gone on to be immortalized in cinema starting as early as the 1950s and 60s. This paper analyses Joram Lürsen’s 2018 film The Resistance Banker as a case study for how cinematic representations of Resistance have evolved over the 70 years since the end of World War II.
Women and Communist China Under Mau Zedong:
Authors: Wielink Michael
Published: May 2019

The mid twentieth century was a tumultuous and transformative period in the history of China. Mao Zedong and the Communist Party seized control and established the People’s Republic of China on October 1, 1949, which was the culmination of over two decades of civil and international war. Mao Zedong’s famed political slogan: “Women Hold Up Half The Sky[1],” was powerful rhetoric, with the apparent emphasis on gender equality and inferred concepts of equality and sameness. Women did not achieve equality with men, nor did they attain egalitarian self-determination nor social autonomy. Nevertheless, when Chinese Communism under Chairman Mao is analyzed we discover women, both rural and urban, were able to challenge social, cultural, and economic gender stratification. Mao envisaged “women’s equality” as a dynamic force with an indelible power to help build a Chinese Communist State. This essay illustrates the ways in which women inextricably worked within Mao’s Communist nation building efforts to slowly erode gender inequalities.  Yet despite the inability of full gender equality to be realized, this era allowed women to experience a broad range of experiences which contained the seeds of change toward breaking down gender inequality. Ultimately, Chinese women under Mao created a more fertile environment so the seeds of equality may continue to grow, perhaps bearing fruit of full “gender equality” in the future.

Improving Access to Specialist Dental Services Using a Telehealth Platform in Victoria, Australia
Authors: Baker Jennifer
Published: May 2019

Australians in rural and remote locations have worse health outcomes compared to that of their metropolitan counterparts and this is due in part to poor access to health services. Public specialist dental services in Victoria, Australia are predominantly offered in the capital city Melbourne. For rural patients this can mean considerable travel, out of pocket costs and delays due to long wait-times. In 2015 Dental Health Service Victoria (DHSV) embarked on a pilot project to enable access to rural clients by linking community dental clinics with the Royal Dental Hospital Melbourne using a Telehealth platform. Aim: The objectives of the pilot were to develop specialist care pathways and enable patient access, support community clinicians to work to full scope through a peer education approach and to identify the appropriate equipment and telehealth platform to support this model of care. Method: DHSV launched its pilot project June 2015 collaborating with four Community Dental sites. The specialties trialled during the pilot project were Oral Medicine, Oral Surgery, Endodontics and Orthodontics. An action based research framework was adopted so that improvements to the operational framework and clinical pathways could be made throughout the life of the pilot. Results: By the end of the pilot programme, DHSV was satisfied the program objectives had been met and the modality was accepted by specialists, community dentists, and patients as a satisfactory substitution for a traditional face-to-face referral and consult mode. Conclusion: Based on this outcome, the programme was endorsed and implemented across the state of Victoria in January 2018.

Introducción. La hiperhidrosis axilar es una condición relativamente frecuente y de difícil manejo, que afecta en forma negativa la calidad de vida del paciente y origina estigmas sociales ya que interfiere con las actividades de la vida diaria. El manejo tradicional de la hiperhidrosis axilar se basa en el uso de preparados tópicos. Como terapias de segunda línea se encuentra la toxina botulínica y diversas técnicas quirúrgicas de destrucción local de las glándulas sudoríparas y la simpatectomía torácica. La técnica quirúrgica de “curetaje” (curetagge) axilar, utilizada en el Servicio de Dermatología de la Universidad Pontificia Bolivariana se propone como una opción para aquellos pacientes que no responden al manejo conservador.Objetivo. Evaluar una técnica quirúrgica llevada a cabo en la Clínica Universitaria Bolivariana y en la Clínica SOMA para el tratamiento de la hiperhidrosis axilar.Metodología. Se trata de un estudio descriptivo, realizado en dos fases: retrospectiva y prospectiva con seguimiento al mes y al año. En este manuscrito se presentan los resultados retrospectivos.Resultados. Se incluyeron 9 pacientes en la fase retrospectiva del estudio, con 18 unidades quirúrgicas. Todos los pacientes habían recibido algún tipo de tratamiento previo. La seriedad de la enfermedad antes de la cirugía era grave en todos los pacientes; al mes de la cirugía era leve en cuatro pacientes y moderada en 5; al año de la cirugía, era leve en dos pacientes y moderada en siete. Siete pacientes consideraron leve el dolor posquirúrgico y hubo una baja tasa de complicaciones.Conclusión. La técnica quirúrgica propuesta para el manejo de la hiperhidrosis axilar es efectiva, con bajo porcentaje de complicaciones, la cual puede ser recomendada como segunda línea de tratamiento para pacientes que no respondan al manejo conservador.

Anglo-Soviet Relations in the Context of the Baltic Problem, 1918–1922
Authors: Sergeev Evgeny
Published: May 2019

The paper deals with the main trends in relations between Great Britain and Soviet Russia in the context of the ‘Baltic problem’, which emerged on the international agenda right after the collapse of the Russian Empire, in the process of the Bolsheviks assuming power and conducting a war against the Whites, the troops of the Entente, and the armies of the new independent states. The author focuses on subsequent stages in the decision-making process, and actual steps taken by London and Moscow with regard to the three new east Baltic states of Estonia, Latvia and Lithuania, taking the latter as a special case. In conclusion, a transition can be traced from the first attempts by Britain to guarantee mere self-governing status for the countries in question, to full recognition of their independence, supported by the Bolshevik government, which, however, opposed the emergence of the Baltic League (or Federation) under the indirect patronage of Britain supported by the League of Nations.
‘The Tsar Would Not Have Taken Away Our Pensions’: Compensation for Russian Army First World War Invalids in Interwar Lithuania
Authors: Jokubauskas Vytautas
Published: May 2019

This article presents an analysis of the support given to Great War invalids in Lithuania: how did veterans of the Imperial Russian army, injured during the First World War, act in order to procure social security (pensions), and how did Lithuanian legalislation change in reaction to their justified expectations. The social welfare situation of Great War invalids who became citizens of the Republic of Lithuania changed in three different stages: a) the period up to 1926; b) 1926 to 1929; and c) following the passing of a separate law on pensions for former Imperial Russian army war invalids in 1930. It was found that support for these First World War invalids in Lithuania was constantly compared to compensation for those who were injured in the Wars of Independence (1918–1920). The size of pensions for these two groups was never equal. Regardless of the fact that attempts were made to make the two types of pensions equal in 1925–1926, barely six months later, Great War invalids started receiving smaller pensions, until they were eventually suspended altogether before a separate law came into effect in 1930. In the article, the reasons for this are explained as a lack of money and political will, and the view of part of society that those injured in the First World War were ‘not fighting for Lithuania’.
Yöneticilerin Demokratik-Katılımcı Yönetim Tarzlarının Çalışanların İç Girişimcilik Eğilimlerine Etkisi

Araştırmanın amacı,
demokratik-katılımcı yönetim tarzının çalışanların iç girişimcilik eğilimleri
üzerindeki etkisini araştırmaktır. Havacılık sektöründe çalışan 136 çalışanın
katılımıyla anket yapılmıştır. Anket verileri çoklu regresyon analizi
kullanılarak analiz edilmiştir. İç girişimcilik ölçeğinin ve
demokratik-katılımcı yönetim tarzı 
ölçeğinin güvenilirlikleri yüksek bulunmuştur (Cronbach’s alpha= .915 ve
.942). Regresyon analizinin sonuçlarına göre demokratik-katılımcı yönetim
tarzının iç girişimciliğin proaktiflik boyutu üzerinde istatistiksel olarak
anlamlı, pozitif ve yüksek düzeyde etkisi bulunmaktadır (p<.001). Özerklik
ve risk alma boyutları üzerinde anlamlı bir etki bulunmamaktadır.
Yaşayanlar Üçlemesinde Bireyciliğin Sonucunda Bireyin Ölümü
Authors: DAĞAŞ Tamer
Published: May 2019

16.yy.da başlayan Aydınlanma Çağı ve
18.yy.da yaşanan Sanayi Devrimi, ilk başta Avrupa kıtası olmak üzere tüm
dünyada hızlı bir değişim hareketine dönüşmüştür. Özellikle Sanayi Devrimi’nin
etkisiyle gelişen savaş sanayi ve geliştirilen silah teknolojileri sonucunda
20.yy.a gelindiğinde art arda iki dünya savaşı yaşanmış, Avrupa’da ortaya çıkan
faşizm olgusu milyonlarca insanın katledilmesiyle sonuçlanmıştır. İnsanlık tarihinde
ilk defa yaşanan dünya savaşları, özellikle İkinci Dünya Savaşı’nda atom
bombasının kullanılmasının da etkisiyle insan yaşamında büyük bir buhran ve
boşluk duygusuna sebep olmuştur. Kapital sermayenin tüm dünyaya egemen olması,
hız kazanan küreselleşme ve metalaşma olguları bireyler arası yabancılaşmayı
arttırmıştır. Kapitalizmin daha fazla kar ve daha fazla ürün satışı hedefini
hayata geçirebilmek için uygulamaya koyulan bireyci yaşam politikaları
Horkheimer’ın deyimiyle; bireyciliğin
sonucunda bireyin ölümü ile sonuçlanmaktadır. Roy Andersson’un Yaşayanlar Üçlemesi 21.yy. insanın
yaşamındaki anlam yitimi, yabancılaşma ve toplumdaki iktidar ilişkileri gibi
olguları açık bir şekilde gözlemleme olanağı sunduğu için örneklem olarak
seçilmiştir. Bu çalışmada 16.yy.da Avrupa’da başlayan Aydınlanma hareketinin ortaya
çıkışından beş yüz yıl sonra yine Avrupa kıtasında ne gibi değişikliklere yol
açmış olabileceği, Foucault’nun Özne ve
İktidar kavramları ve Horkheimer’ın
“bireyciliğin sonucunda bireyin ölümü”
söylemi üzerinden Yaşayanlar Üçlemesinde
analiz edilecektir. Ayrıca bu çalışmanın, Roy
Andersson sinemasının genel hatlarını ortaya çıkartarak alana katkı
sağlaması beklenmektedir.
Melodram ve Tragedyanın Ahlaki Evreninin Çağan Irmak Filmlerindeki Dönüşümü
Authors: TURGAY Duygu
Published: May 2019

Gerek
melodram gerekse tragedya olsun her iki tür de ahlak dersi vererek ahlaki olanı
vurgulamayı amaçlamaktadır. Melodram, ahlaksal ölçüler içinde sıralanmış
olaylar dizisinden oluşan bir türdür. Aristoteles’in tanımı ile tragedya da
ahlaksal bakımdan ağırbaşlı, başı ve
sonu olan, belli bir uzunluğu bulunan bir eylemin taklididir. Çalışmada melodram ve
tragedyanın ahlaki değer vurgusuna dayanan anlatısının Çağan Irmak filmlerine
nasıl yansıdığı ve bu filmlerde bu yansımanın nasıl bir dönüşüm geçirdiği
sorularına cevap bulmak amaçlanmıştır. Bu amaç doğrultusunda melodramın ve
tragedyanın “ahlaki” tanımı ve bu tanımın her iki türün anlatı yapısına
yansıması üzerinde durulmuştur. Ayrıca çalışmada Çağan Irmak’ın örneklem alınan
filmleri incelenerek Çağan Irmak’ın “ahlak” kavramını nasıl ele aldığı üzerinde
de durulmaktadır. Çalışmada Çağan Irmak’ın Issız
Adam (2008), Dedemin İnsanları (2011),
ve Unutursam Fısılda (2014) olmak
üzere üç filmi örneklem olarak alınmıştır. Çalışmada örneklem olarak alınan bu
filmlerde melodram ve tragedya kavramları çerçevesinde sinematik imajlar
incelenmiştir. Çağan Irmak, filmlerinde hem melodram hem de tragedyanın
unsurlarından ve anlatı yapısından yararlanmaktadır. Ayrıca Çağan Irmak’ın
filmlerinde, ahlaki değer vurgusu yaptığı da söylenebilir. Fakat bu ahlaki
değer vurgusu ne melodramda olduğu gibi keskin çizgilerle birbirinden ayrılmış
zıtlıklar üzerinden yapılmakta ne de tragedyada olduğu gibi ahlaki yönden üstün
karakterler ile gerçekleştirilmektedir. Çağan Irmak filmlerinde, toplumsal
ahlaki normlardan ve de karakterlerin eylemlerinden çok, evrensel ahlaki
normlara ve karakterlerin duygu durumlarına ağırlık verilerek bu filmler,
ahlaki yönden melodram ve tragedya türlerinden farklılaşmıştır.
Metinlearasılık, Hegel ve Matrix
Authors: RIZVANOĞLU Eren
Published: May 2019

Metinlerarasılık kavramı,
kökenini Bakhtin’in söyleşimcilik düşüncesinden alır. Bakhtin’e göre her anlam
bir yanıtla doludur ve konuşan kişi, konuştuğu konu hakkında konuşan ilk kişi
asla değildir. Bu yaklaşım dünya hakkında ortaya koyduğumuz her yargının açık
uçlu olduğu ve her iddianın da doğası gereği söyleşimsel olduğunu öne sürer.
Kristeva, Bakhtin’in söyleşim kavramını, onun metin merkezli yaklaşımına bağlı
kalarak ama tarihsellik vurgusunu gözardı ederek, metinlerarasılık kavramıyla
karşılar. Kristeva açısından her metin bir alıntılar mozaiğidir. Bu durumun
sonucu olarak, metnin anlamı, başka metinlerden kendisine taşınan açık uçlu bir
anlamdır. Sinema açısından bu kavram, kuramsal bir okuma açısından çok elverişlidir.
Nitekim her film başka filmlere göndermelerle doludur ve belki de kendi
değerini sinemanın mirasına bu göndermelerinden edinir. Birçok açıdan sinemanın
seyrine etki eden bir film olarak Matrix,
bu yaklaşımı birçok anlamda içinde barındırır. Baudrillard’ın üst gerçeklik
düşüncesinden, Platon’un Mağara Alegorisine, Kartezyen düşünceden çağdaş
nöröfelsefe yaklaşımına kadar birçok felsefi gönderme içerir. Biz bu çalışmada,
metinlerarasılığın kuramsal çerçevesi içerisinde Matrix’i Hegel’in efendi köle diyalektiği ve mutsuz bilinç
kavramları bağlamında değerlendirerek, Matrix’in
arkasında bulunan düşünsel alanın bir kısmını göz önüne çıkarmaya çalışacağız.
