Pada analisis kapasitas saluran drainase menggunakan data curah hujan 10  tahun  terakhir  dengan  analisa  frekuensi  hujan  menggunakan  metode distribusi Log Person III untuk mendapatkan curah hujan rencana tiap tahun. Perhitungan  debit  banjir  rencana  pada  analisis  saluran  drainasenya menggunakan metode Weduwen. Hasil perhitungan kapasitas saluran drainase memperlihatkan bahwa terdapat saluran yang tidak aman karena debit saluran eksisting (Qs) lebih kecil dari debit banjir rencana (Qr) pada saluran 1, saluran 6 dan saluran 14 sehingga saluran tesebut perlu untuk diredesain. Kapasitas saluran tidak aman pada saluran 1 terjadi pada kala ulang 2 sampai 100 tahun. Untuk  kapasitas  saluran  tidak  aman  saluran  6  terdapat  pada  kala  ulang  2, sampai 100 tahun. Untuk kapasitas tidak aman saluran 14 terdapat pada kala ulang  2 sampai 100 tahun.  Untuk kapasitas saluran  drainase  lainnya  sudah aman tetapi kondisinya perlu diperhatikan pada saluran terdapat rumput dan sedimen  yang  dapat  mengurangi  kapasitas  dari  saluran  itu  sendiri  sehingga dapat menyebabkan genangan air di sekitar saluran. Untuk perhitungan redesain saluran 1, 6 dan 14 dapat ditinjau dari debit banjir rencana dan elevasi saluran yang  telah dihitung sebelumnya sehingga dapat dengan mudah menentukan dimensi saluran ekonomis yang sesuai dengan debit rencananya.

Tanah  dasar  (subgrade)  merupakan  lapisan  tanah  asli  yang  terletak paling bawah yang berfungsi sebagai tempat perletakan lapis perkerasan dan mendukung konstruksi diatasnya. Daya dukung suatu lapisan tanah tertentu tergantung dari kepadatan tanah yang menyusun lapisan tersebut, semakin kecil CBR (California Bearing Ratio) suatu lapisan dari jenis tanah tertentu maka lapisan yang dibuat diatasnya haruslah semakin tebal. Salah satu tanah yang biasa ditemukan pada suatu konstruksi yaitu jenis tanah lempung.Tanah lempung memiliki kemampuan menyerap air yang cukup tinggi dan kondisi pengaliran air sangat rendah. Tanah lempung merupakan jenis tanah dengan daya dukung rendah, pengaruh air sangat besar terhadap perilaku fisik dan mekanisnya. Dari hasil penelitian/pengujian terhadap sampel tanah, secara umum menunjukkan semakin banyak persentase penggunaan semen maka daya dukung tanah semakin baik, namun jika penggunaan pada jenis tanah lempung berplastisitas rendah, dianjurkan penggunaan difa soil stabilizer yang digunakan secara bersamaan  dengan  semen  persentase  optimum  pada  4%  dari  berat/volume tanah kering, yang diparameterkan melalui sifat mekanis tanah meliputi nilai hasil uji  pemadatan  tanah/uji  proctor  (kadar  air  optimum  dan  berat  isi  kering maksimum   tanah)   dan   nilai   hasil   pengujian   CBR   laboratorium. Terjadi peningkatan daya dukung tanah yang diindikasikan adanya peningkatan nilai- nilai CBR tanah campuran dari nilai CBR tanah asli, pada persentase penambahan difa soil stabilizer dan semen sebesar 4% ternyata telah mampu meningkatkan nilai CBR tanah dasar menjadi 6,37% dari CBR tanah asli sebesar 2,7%, nilai ini telah memenuhi batas minimum CBR tanah dasar/sub grade yang ditentukan oleh spesifikasi umum Bina Marga Tahun 2010 yaitu sebesar 6%.

Vertical fracture affecting production well flooding as feature of geological section of left-bank part of Astrakhan gas condensate field
Authors: Lutfullin Roman Nazifovich , Golchikova Nadezhda
Published: May 2023

The left-bank part of the Astrakhan gas condensate field (AGCF) is represented by a carbonate reservoir of a complex type. The study of the geological structure and properties of the deposit is a fundamental factor for its successful operation. There are presented the main characteristics of the lithological composition and filtration-capacitance properties of the carbonate productive reservoir C2b of the left-bank part of the AGCF, described the specific features of their formation. One of the important features of the productive carbonate reservoir of the left-bank part of the AGCF is the anisotropy of filtration-capacitance properties in different directions. Special attention was paid to the description of horizontal and vertical fracturing, and post-sedimentation processes. There is proposed a probable mechanism of fracturing in areas of high occurrence of productive strata. The problem of well flooding is of great importance for the development of AGCF. Different factors of geological and technical order were investigated (the position of drilled faces and perforation intervals/open barrel relative to the position of the gas-water contact). No regularities were revealed. Based on the study of field data, zones of vertical fracturing have been identified, which caused the flooding of wells. It is possible to map watering zones according to the structural parameters of Bashkir deposits at the highest roof marks. There has been suggested a probable model of well flooding in the left-bank part of the AGCF associated with the tectonic factor and post-sedimentation processes of external influence. The actual data are presented, including a diagram of wells with a water-gas factor WGF ≥ 100 cm3/m3 depending on the occurrence of the roof C2b, which clearly confirm the predominance of a crack-pore collector with significant communication in the described zones.

Published: May 2023

Introduction

Due to the severe side effects of non-steroidal anti-inflammatory drugs, there is an urgent need to find new natural or synthetic chemicals that could act as selective inhibitors of cyclooxygenase-2 (COX-2). The most valuable source of new bioactive compounds and potential drugs are plants. The present study aimed at the investigation of LevidorTM, a patented composition based on oil from the seeds of Nigella sativa and extract from the root of Angelica archangelica, regarding its potential anti-inflammatory effects on the molecular level.

Materials and Methods

Studies were carried out with the use of murine macrophages (RAW 264.7), human monocytes (U937), and rat pheochromocytoma (PC-12) cell lines. The cytotoxicity of the LevidorTM extract was evaluated by MTT assay. The concentration of pro-inflammatory cytokines (IL-6, TNF-α) was evaluated by ELISA. Moreover, the analysis of COX-1 and COX-2 mRNA expression levels by RT-PCR, as well as protein level by Western blot and immunofluorescent staining, were assessed.

Results

The LevidorTM extract did not impact cell growth and showed anti-inflammatory effect in the present study. It was able to decrease the level of IL-6, TNF-α and suppress transcription of COX-2, whereas it had no effect on COX-1.

Conclusions

Obtained results showed that LevidorTM exhibits strong anti-inflammatory properties and may provide a significant alternative to traditionally used medicines in acute pain and chronic inflammation.
Transfer of Personal Data to Third Countries and the “Equivalent Level” of Protection According to the European Court of Justice
Authors: Furramani Emanuela
Published: May 2023

The focus of this study is the transfer of personal data to third countries or international organizations according to EU Regulation No. 679/2016 (GDPR) on the protection of personal data. The primary goal of this Regulation concerning data transfer to third countries is to ensure that the subject’s rights and freedoms are safeguarded at the same level as provided by GDPR. According to GDPR, before any transfer to a third country or international organization, it must first be ascertained whether the European Commission has established that a third country ensures an adequate level of protection. Regarding personal data protection in the third state, the Court of Justice of the European Union has intervened on different occasions. In the last decision, in 2020, the Court declared invalid the European Commission’s Decision No. 2016/1250 on the adequacy of the protection provided by the EU-US Privacy Shield (CJEU, Schrems II, 2020, July 16) because it does not provide effective and enforceable rights for personal data subjects in cases of interference. According to the Court of Justice of the European Union, the US does not guarantee an “essentially equivalent” level of protection to that provided by the European Union under Article 45(1) GDPR, read in conjunction with Articles 7, 8, and 47 of the European Union’s Charter of Fundamental Rights, which guarantee respect for private and family life, personal data protection, and the right to effective judicial protection.

Authors: Guneri Emine , Ozpozan Nilgun Kalaycıoglu
Published: May 2023

Perovskite materials have many interesting properties such as modulation of the optical band gap and the properties of quantum wells. In addition, they have a stable structure. For these reasons, perovskites have attractive properties for optoelectronic devices. Additionally, the structural and optical properties can be changed by means of different halide atoms doped into materials. In this study, the effect of iodine on the structural, and optical properties of perovskite thin films was investigated. KCaCl2 I and KCaCl3 perovskite were prepared by chemical bath deposition on a glass substrate. The crystal structures of the films were determined by X-ray diffraction. X-Ray Diffraction (XRD) analysis revealed that the films had a crystalline structure. In addition, KCaCl2 I perovskite thin film has better crystalline than KCaCl3 perovskite thin films. Linear optical parameters were determined using transmittance and absorbance measurements. And then, the optical band gap values, extinction coefficient, refractive index, and dielectric constants were determined as linear optical properties. It was understood that these properties were affected by iodine.
Barrier Modification by Methyl Violet Organic Dye Molecules of Ag/P-Inp Structures
Authors: Güllü Ömer
Published: May 2023

This work includes fabrication and electrical characterization of Metal/Interlayer/Semiconductor (MIS) structures with methyl violet organic film on p-InP wafer. Metal(Ag)/ Interlayer (methyl violet =MV)/Semiconductor(p-InP) MIS structure presents a rectifying contact behavior. The values of ideality factor (n) and barrier height (BH) for the Ag/MV/p-InP MIS diode by using the current-voltage (I-V) measurement have been extracted as 1.21 and 0.84 eV, respectively. It was seen that the BH value of 0.84 eV calculated for the Ag/MV/p-InP MIS structure was significantly higher than the value of 0.64 eV of Ag/p-InP control contact. This situation was ascribed to the fact that the MV organic interlayer increased the effective barrier height by influencing the space charge region of inorganic semiconductor. The values of diffusion potential and barrier height for the Ag/MV/p-InP MIS diode by using the capacitance-voltage (C-V) measurement have been extracted as 1.21 V and 0.84 eV, respectively. The interface-state density of the Ag/MV/p-InP structure was seen to change from 2.57×1013 eV-1cm-2 to 2.19×1012 eV-1cm-2.

Published: May 2023

The new media concept, which emerged with the rapid change of technology, has also changed the perception of society to mass media. It is an absolute reality that the changing radio concept in the digitizing period has changed and transformed the listener along with it. It has also reformed the new media audience, which has been reformed with the convergence of mass media with technology, not only as an audience but also as a participant. As a result of convergence, new concepts such as interaction, synchronicity and mass unification have emerged. While interaction in the traditional media is provided at a limited level, content in the new media is often determined by the audience. From the point of view of new media and user relations, radio has become the medium of communication that can adapt to this change in the easiest way and change contents in this direction. the Internet has offered a radio technology to radio listeners that allows the radio to establish its own radio. All these technological developments and the activation of the audience have reshaped the radio and listener relationship. The main aim of this study is to reveal how the radio, a warm communication medium, is shaped its own language and the relationship established with the audience through technology. In this direction, a structured in-depth interview will be held with 24 people working at Anadolu University in February 2018. These people will be randomly determined according to their socio-economic status. According to the Socio-economic Statutes, 8 faculty members, 8 civil servants and 8 workers will be selected. The selected sampling will ask questions such as radio listening habits, why they listen to the radio and what the effect of participating in radio programs for a democratic society will be in order to define the link they establish with the radio.

Published: May 2023

Brucellosis remains a public health problem in many Mediterranean countries. In this work are presenting data of human brucellosis clinics and treatment in a sample of hospitalized patients. Methods: All patient charts at regional hospital in Gjirokastra, Albania were systematically reviewed, during the period 2016-2021. All hospitalized patients with a laboratory confirmed diagnoses of brucellosis were included in the study. Variables of interest were clinical symptoms, clinical course and treatment provided. Sub-acute brucellosis was defined as clinical persistence of 3-12 months while cases with clinical symptoms persisting for ≥12 months were defined as chronic brucellosis. Results: 79% of the 86 patients were male and residing in rural areas. Fever, profuse sweating and arthralgia were the most common clinical signs. Around 70% of the brucellosis patients showed all these three symptoms. Despite a systematic tendency for more frequent presence of high fever, increased sweating and arthralgia on younger patients we could not find statistically significant differences among demographic categories. 18.6% of cases presented persistence of clinical signs after at least 3 months from the moment of the diagnoses. Almost 7% of the cases were classified as chronic cases. 75.6% of all patients were treated with a combination of doxycycline and ceftriaxone antibiotic regime. Conclusions: The massive use of a cephalosporin in treatment of brucellosis cannot be justified and may reflect a larger problem related to population awareness and health provider attitudes concerning antibiotic use in Albania. The results of this study may assist future interventions to improve brucellosis case management at hospitals or primary health care level as well as national measures at a larger scale for control of the disease.

Republic of North Macedonia in the last several years undergoes comprehensive social protection reform. The reform processes have been focused on furthering the processes of deinstitutionalization, decentralization and pluralization of social services delivery. The transformation of social protection institutions has been one of the key priorities in this period, specifically out-of-family services for children. In this respect, alternative care services for children without parents and parental care has been strengthened and promoted. Foster care as a traditional form of protection has been given particular attention and has undergone considerable changes. This article will review key reform processes in the domain of social protection in the country, with focus on social services for children without parents and parental care. To do this, results from recent empirical research will be presented. Mixed methodology research findings target current conditions in respect to foster care, small group homes and supported living as services used for placement of children without parents and parental care as well as professional approaches used to provide for individualized and child-tailored care. Cross-cutting issues relate to human rights, basic human needs and social integration of children.
Black Awakening in Obama’s America: The End of an Illusion
Authors: Vukelić Tatjana
Published: May 2023

The aim of this study is to present and describe the social and political situation in the United States before and after Barack Obama’s presidency regarding Black people and their position in the American mainstream society. What exactly does Obama’s election portend for race in America? This essay uses the tremendous racial disparities in the American social and political system to assess race and racism as key features of contemporary society. In America, African Americans were, and are, locked in a “racial prison”. As Blacks, their identities were defined in opposition to whites and whitness. Of course, Blacks could free themselves by changing their names, reframing their identities, and discharging their culture and heritage. To do so, as Malcolm X pointed out, required some radical action, a kind of suspension of judgement that would permit Blacks to see themselves in tension with the normative white gaze. As long as African Americans place their faith in political rightness and correctness of American democracy, they would never know what it feels like to be equal. The hope and optimism that coursed through Black America in anticipation of Obama’s victory as the first Black president in 2008 seemed a million miles away. It seems like slavery was never abolished; it was only redesigned.
Legal Analysis of the “Responsibility to Protect” Concept in the Context of Globalization
Authors: Kurnicki Leszek Robert
Published: May 2023

In this article, the concept of “responsibility to protect” is considered as one of the aspects of legal globalization. According to this concept, sovereignty is not a right and not a privilege, but an obligation of the state, and if the state is unable to ensure its sovereignty, the international community has the right to intervene in the current situation. Such an approach completely changes the traditionally established ideas about the subject of state sovereignty, since the very possibility of other states interfering in the affairs of another state is a violation of the principle of sovereignty in its generally accepted understanding.

This article presents the lived experiences of unemployed graduate youth in Botswana, and it is part of a doctoral thesis titled, “Enhancing Active Labour Market Programmes for Improved Youth Livelihoods: A Study of Unemployed Graduate Youth in Botswana.” The qualitative study drew data from focus group discussions with unemployed graduate youth for this article and adopted the sustainable livelihoods framework. The data used were derived from the narrations as stated by unemployed graduate young people in three localities of Gaborone (urban), Kanye (urban villages), and Oodi/Modipane (rural areas) who partook in the study and are, therefore, not representative of the entire population of those unemployed in Botswana. Rather, the study highlights the unemployed young graduates’ lived experiences. Among the highly mentioned experiences of these unemployed graduate youth were social exclusion by their communities, family and friends; unmitigated blame; loss of respect, esteem, and self-esteem; wrongful accusations; and unappreciated domestic work.
Factors Influencing the Spread of SARS-CoV-2 in Africa
Authors: Lekalakala Molebogeng Ruth
Published: May 2023

The emergence of the global COVID-19 pandemic has continued to cause havoc and untold suffering worldwide. The pandemic’s pattern of spreading has varied between continents and indeed within countries. Studies looking at the factors affecting the dynamics of COVID-19 in African countries are limited. In this study we attempt to assess and understand the differential spread of COVID-19 in Africa by looking at South Africa (Southern Africa), Senegal (West Africa), Egypt and Morocco (North Africa), Rwanda (Central Africa) and Kenya (East Africa). We observed a high prevalence of COVID-19 in South Africa, Morocco and Egypt. Furthermore, South Africa ranks first in the number of reported confirmed COVID-19 cases and related hospitalisations and deaths in Africa. Senegal (Western Africa) shows lower confirmed cases and death rates. Based on the findings, it is crucial for these countries’ governments and health authorities to be vigilant in mobilising effective medical resources and to continue educating their citizens in order to curb the spread of the coronavirus.
The Legal Complexities of Terrorism as an International Crime Following the Recruitment and Enlistment of Child Soldiers in the Cabo Delgado, Mozambique Insurgency War
Authors: Hungwe Brian
Published: May 2023

The conscription of children in military conflicts within the Southern African Development Community (SADC) region was more peculiar to the Democratic Republic of Congo after the Angolan and Mozambican civil wars subsided into peace during the late 1990s. The resurgence of child soldiers in Mozambique under a new Islamic-inspired terrorist phenomenon adds a terrifying dimension that brings legal complexities around defining terrorism and resituating it separately as a crime within the jurisdiction of the International Criminal Court (ICC). The spectre of terrorism—as the current prime inducement of children into hostilities in Mozambique—has regional, political, economic and security implications, given its magnitude and recurring nature. This research is qualitative in form and its objective is broadening the understanding of terrorism, addressing the recurring recruitment of children into armed conflicts within the SADC region, and making a case for the inclusion of terrorism in the Rome Statute. This is important for the SADC, which had sloughed off the heinous side of civil wars. Research demonstrates that systemic violation of child rights takes an enormous toll on societies, given its extensive physical and psychological harm, and that often children in war-torn societies make up half the population. The findings are that the inclusion of terrorism within the scope of the ICC broadens international accountability mechanisms and acts as a deterrent for the future enlistment of children into armed conflicts.
The Family as Black Nationalism: Cosmopolitan Archetypes in Black Popular Township Television Films
Authors: Selekane Nkosinathi Leonard
Published: May 2023

The apartheid regime conspired to advance black ethnic divisions to facilitate the homelands and diminish the threat of black people to South Africa. From 1994, the democratic dispensation has engaged in various nation-building attempts to solidify a united South Africa that is multicultural and multilingual in conjunction with a progressive Constitution. Popular township films by Ekasi: Our Stories and Lokshin Bioskop have ventured into this arena which was the forte of the South African Broadcasting Corporation, to engage in storylines that encourage nation-building. In this article, I argue that popular films have emerged to represent cosmopolitan tropes that galvanise Black Nationalism. Also, the films engage negative black tribal stereotypes that, if not attended to, could result in black disunity. It can also be argued that the latter has been a stimulant for African conflicts, occasionally causing genocides. This article explores the role popular films play in conveying a nation-building narrative that sustains Black Nationalism and reconciliation in post-apartheid South Africa.

This article and study examined youths’ interest in entrepreneurship development in Nigeria. Data were collected through a systematic review of relevant literature and a structured questionnaire. The data from the questionnaire were subjected to descriptive and inferential statistics. The findings showed that 60.25% of the respondents were not aware of any government programme for entrepreneurship development. Also, 52% of the respondents did not think the government provided the necessary support for the adequate development of entrepreneurship. A total of 58.25% of the respondents expressed their intention to start up a business within three years, and 54% of the respondents believed that they had the capacity to start and run a business on their own. Youths’ perception of the role of government in the development of entrepreneurship was found to have a significantly weak and negative relationship with their intention to start up a business (r = -0.103, p < 0.05). Also, youths’ perception of the role of government in the development of entrepreneurship was found to have a significantly weak and negative relationship with their ability to start up a business (r = -0.104, p < 0.05). This indicates that youths’ interest in entrepreneurship and a willingness to start up businesses largely occur outside the framework of government support. However, this does not exonerate the government from promoting the development of entrepreneurship. Therefore, this paper contends that the Nigerian government should create a suitable environment for entrepreneurship to thrive among youths.
Prosódia e síntese da fala: uma revisão integrativa da literatura
Authors: Galdino Julio Cesar , Oliveira Jr. Miguel
Published: May 2023

Este é um trabalho de revisão integrativa acerca de estudos feitos entre as relações da prosódia e da síntese de fala. A partir da pergunta de pesquisa “Como a prosódia tem sido considerada em trabalhos que visam o aprimoramento da síntese de fala?”, realizamos uma busca no Google Scholar com a sintaxe (prosódia OR entoação OR “frequência fundamental”) AND ("text-to-speech" OR TTS OR "síntese de fala" OR “síntese da fala”). Avaliamos os títulos e os resumos dos estudos e, mediante a observação de critérios de inclusão e de exclusão, encontramos 10 estudos, entre 2010 e 2021, que dissertam sobre prosódia e síntese de fala. Os trabalhos selecionados indicam que a frequência fundamental (ou pitch) é o recurso mais expressivo para o aprimoramento da fala sintética, embora os sistemas de conversão de texto para a fala utilizem outras características prosódicas para aprimorar seu desempenho. Além disso, os resultados desta revisão mostraram que há ainda pouco estudo no Brasil sobre a relação entre a prosódia e a síntese de fala e que é importante a pesquisa conjunta entre pesquisadores de áreas da linguística e das engenharias, a fim de se obter melhores resultados em sistemas de síntese de fala.

Background. NPWT is widely used to manage hard-to-heal wounds, and many different devices are available. Personal-use NPWT systems are becoming more popular, although current options have limited functionality. Purpose. The primary objective was to determine acceptable progress of wounds towards a predefined goal of therapy for a variety of open wounds being treated with a novel NPWT personal-use system with enhanced functionality. Methods. In this prospective, nonrandomized, interventional study, patients were treated with a personal-use NPWT system over 4 weeks, initially in a wound care clinic setting, and were discharged home with the device. Clinician satisfaction with the device was also evaluated. Results. Ten patients were evaluated. Acceptable progress towards all predetermined goals was reached for all patients; a median reduction in wound volume of 84.6% and improved granulation was achieved within the 4-week treatment period. No device-related deficiencies were reported. In general, clinicians were satisfied with the device’s ease of use and mobility. Conclusion. Personal-use NPWT is easy to use, has positive effects on healing on a variety of wound types, and is well accepted by clinicians.
Pilonidal Disease of the Anterior Perineum: An Unusual Presentation and Review of Current Practice Guidelines

Introduction. Pilonidal disease is a common condition of the gluteal cleft region, but involvement of the anterior perineum is rarely reported. Surgical options for gluteal cleft disease include simple fistulotomy, excisional procedures with primary closure (ie, Bascom cleft lift, Karydakis and Limberg flaps), or excision with secondary healing. The Bascom cleft lift described here is an excisional procedure involving a rotational flap with an off-midline closure. Deep tissue is salvaged allowing for proper contouring of the gluteal cleft, resulting in a cosmetically pleasing result. Case Report. A 20-year-old man with recurrent pilonidal abscesses of the gluteal cleft underwent a Bascom cleft lift procedure for definitive care of his disease. During the procedure, involvement of the anterior perineum was found. Given the location of the pits relative to the flap, the anterior perineal disease was treated only with removal of hair from within the pits and clipping the hair of the perineum. Conclusion. While this case highlights the current standard of care and surgical options for pilonidal disease, the ideal surgical options for rare cases of pilonidal disease of the anterior perineum remain to be determined.
Girl on Fire – Links between sex, firefighters’ clothing, safety, confidence and wear and tear

Firefighters are exposed to high risks and hazards, such as flames and smoke, in their daily lives. To be protected against these risks, firefighters wear protective clothing. As an employer, it is the duty to provide firefighters with good protection according to DIN EN 469. To do so, it is necessary to select, procure and maintain suitable firefighters' protective clothing. In order to identify weaknesses in the above steps and to develop and present proposals for remedying the identified weak points, an empirical study was conducted. In preparation for this study, interviews were first conducted with members of fire brigades. Based on the interviews, the relevant standards and regulations for fire fighters´ clothing were classified and areas of tension between the standards and regulations as well as their design in everyday fire brigade life were identified. Based on this, a standardized quantitative survey was conducted and the answers of the respondents were empirically evaluated. The evaluation examined both the respondents' answering behavior and the dependency between the answering behavior for different questions due to demographic differences. A key finding is that women firefighters are less satisfied with their firefighting clothing compared to men firefighters. The firefighters' clothing fits them worse. They do not feel as safe and comfortable. Moreover, woman have less confidence in the protective clothing. There is a correlation between the fit of the clothing and the satisfaction, confidence and feeling of protection
Is there still a place for linearization in the chemistry curriculum?
Authors: McCluskey Andrew
Published: May 2023

The use of mathematical transformations to reduce non-linear functions to linear problems, which can be tackled with analytical linear regression, is commonplace in the chemistry curriculum. The linearization procedure, however, assumes an incorrect statistical model for real experimental data; leading to biased estimates of regression parameters. As, non-linear optimization is more accessible than ever with modern computing by introducing linearization, without a detailed discussion of the shortcomings, we are failing to equip students with the correct tools for formal data analysis. I hope that this commentary will start a discussion in the community around the place of linearization in the chemistry curriculum.
Enigmatic Alternatives for Epoxides in Graphene Oxide

The structural mystery of the long-known graphene oxide (GO) unfolds as one of the formidably abstract conceptual problems among nanomaterials. Generally construed as the oxidized form of graphene, it is variously proposed to host a variety of functional groups with oxygen and hydrogen. Theoretical studies are abundant on the highly-strained epoxides, while larger cyclic ethers having one or more oxygen atoms and vinylogous carbonyls are paid scant attention even though they are predicted by several structural models. The nature of the geometric and electronic structure of these alternative functional groups, the preferred distribution on the graphene lattice, comparative stability, etc., remains unexplored. Our systematic inquiry into the impact of hexagonal and periodic constraints on these mystic functional groups unveils several surprises. Among those that retain the hexagonal carbon backbone, epoxides are surprisingly more stable than larger ethers despite the excessive strain associated with their acute triangular geometry. Epoxidation conserves the planarity of the carbon backbone that allows their optimal distribution on the lattice by reducing the repulsive interactions from oxygen lone pairs and π-electrons. These findings categorically rule out the possibility of 1,3 ethers in GO and settle the long-standing debate on its existence. They face severe steric repulsion even in low dimensional systems that tear down the σ-skeleton of graphene completely apart, reducing its dimensionality. We show that selective breaking of the σ-bonds is preferred over epoxides if backed by cyclic delocalization of electrons. Particularly, 1,6-diones in trans orientation are thermodynamically favored and justify the large holes experimentally observed through microscopic imaging.
