Abstract. The white chalk cliffs on the south coast of England are one of the most iconic coastlines in the world. Rock coasts located in a weak lithology, such as chalk, are likely to be most vulnerable to climate change-triggered accelerations in cliff retreat rates. In order to make future forecasts of cliff retreat rates as a response to climate change, we need to look beyond individual erosion events to quantify the long-term trends in cliff retreat rates. Exposure dating of shore platforms using cosmogenic radionuclide analysis and numerical modelling allows us to study past cliff retreat rate across the late-Holocene for these chalk coastlines. Here, we conduct a multi-objective optimisation of a coastal evolution model to both high-precision topographic data and 10Be concentrations at four chalk rock coast sites to reveal a link between cliff retreat rates and the rate of sea level rise. Furthermore, our results strengthen evidence for a recent acceleration in cliff retreat rates at the chalk cliffs on the south coast of England. Our optimised model results suggest that the relatively rapid historical cliff retreat rates observed at these sites spanning the last 150 years last occurred between 5300 and 6800 years ago when the rate of relative sea level rise was a factor of 5–9 times more rapid than during the recent observable record. However, results for these chalk sites also indicate that current process-based models of rock coast development are overlooking key processes that were not previously identified at sandstone rock coast sites. Interpretation of results suggest that beaches and heterogenous lithology play an important but poorly understood role in the long-term evolution of these chalk rock coast sites. Despite these limitations, our results reveal significant differences in intertidal weathering rates between sandstone and chalk rock coast sites, which helps to inform the long-standing debate of ‘wave versus weathering’ as the primary control on shore platform development. At the sandstone sites, subaerial weathering has been negligible during the Holocene. In contrast, for the chalk sites, intertidal weathering plays an active role in the long-term development of the shore platform and cliff system. Overall, our results demonstrate how an abstract, process-based model, when optimised with a rigorous optimisation routine, can not only capture long-term trends in transient cliff retreat rates but also distinguish key erosion processes active in millennial-scale rock coast evolution at real-world sites with contrasting rock types.
The predictive power of ice sheet models and the regional sensitivity of ice loss to basal sliding parameterisations: A case study of Pine Island and Thwaites Glaciers, West Antarctica
Authors: Barnes Jowan Menhinick , Gudmundsson G. Hilmar
Published: June 2022

Abstract. Ice sheet models use a wide range of sliding laws to define a relationship between ice velocity and basal drag, generally comprising some combination of a Weertman-style power law and Coulomb friction. The exact nature of basal sliding is not known from observational data, making assessment of the suitability of different sliding laws difficult. The question of how much this choice could affect predictions of future ice sheet evolution is an important one. Here we conduct a model study of a large sector of the West Antarctic Ice Sheet (WAIS), a particularly critical component of the cryosphere, using a range of sliding parameterisations, and provide an assessment of the sensitivity of ice loss to the choice of sliding law. We show that, after initialisation, various sliding laws result in broadly similar ranges of sea-level contribution over 100 years, with the range primarily dependent on exact parameter values used in each sliding law. Comparing mass loss from Thwaites and Pine Island glaciers, and the neighbouring regions, reveals significant qualitative geographical differences in the relationship between sliding parameters and the modelled response to changes in forcing. We show that the responses do not necessarily follow universal systematic patterns and, in particular, higher values of the sliding exponent m do not necessarily imply larger rates of mass loss. Despite differences in the magnitudes of ice loss and rates of change in the system, all our experiments display broad similarities in behaviour which serve to reinforce the decade-to-century-scale predictive power of ice sheet models, regardless of the choice of basal sliding.
Inbetween writing: philosophy and catachresis
Authors: Webb Jen
Published: June 2022

When I was doing a degree in literature some years ago and researching women’s writing, I came across Rachel Blau DuPlessis’s article ‘For the Etruscans’ (DuPlessis 1987), and with it a whole new way of thinking about text. It was published, innocently enough, in a conventional (pace, editor Rick Rylance) book of LitCrit, but from its opening paragraphs was clearly doing something else, and going somewhere else, away from the norm. I looked for the conventions of academic English and found instead: Sentence fragments. Loose ideas. FORMATTING designed to ______ claim attention. Exclamation marks! All this in an article on women’s writings that obviously belonged to the ‘criticism’ genre, that was itself highly literary in a postmodern sense, and at the same time was intruded upon (contaminated?) by disjunctures, shards of autobiography, blind alleys, and worst of all, personal comments.
An exegesis concerning the novel Fragments of a Map
Authors: Brady Tess
Published: June 2022

Fragments of a Map explores the journey towards completion for two women. Their journey is mirrored in the narrative by the women’s attempt to unravel the provenance of the Vinland Map. Central to the narrative is the question: “Is the Vinland Map a valuable 15th century map or a clever forgery?” The novel, through its concerns and structure, plays with the notion of research in the creative arts. This exegesis comments upon the concerns of the novel, and the writing and research processes.

Published: June 2022

Spinel ferrites nanoparticles play a significant role in our everyday lives. In the current work, La3+ doped Co-Zn ferrites with chemical formula Co0.5Zn0.5LaxFe2-xO4 (x = 0.00 to x = 0.2 with step size 0.04) was effectively prepared by sol gel technique. The formation of FCC spinel structure was confirmed by X-Ray diffraction (XRD) analysis. The average crystallite size were calculated to be in the 8 nm to 13 nm range. The lattice parameters were found to be decreased with the doping of lanthanum (La3+) contents. X- Ray density is analyzed to increase as the concentration of (La3+) doping increases, this is due to the fact that La3+ ion has a higher molar weight than Fe3+ ion. The spinel phase structure was affirmed by using FTIR.The two main absorption bands ?1 and ?2 are referred to tetrahedral stretching band and octahedral stretching band respectively, is found to be in the range of at around 400-530 cm-1. Spinel ferrites, such as Co-Zn spinel ferrites, have dielectric features that make them ideal for use in high-frequency applications. With new potential applications being investigated all the time. Physical properties, synthesis method, as well as sintering temperature and time, are all important factors in regulating the properties of dielectric materials. The dielectric features were measured in the frequency of 1 MHz to 3 GHz range. Lowered dielectric parameters studied across a higher frequency range recommend that such nano crystalline ferrites could be used to fabricate the equipment needed to perform at GHz frequencies.

Published: June 2022

Silver nanoparticles were prepared via process of chemical reduction using sodium borohydride as reductant. The prepared nanoparticles were then utilized for synthesizing various compositions of nanocomposites with polymeric matrix of poly (vinyl alcohol). For doing so, the nanoparticles were dispersed in the polymer solution by vigorous stirring. The solutions of the nanocomposites were cast in films. The nanocomposite films were used for various characterization techniques; out of which three are being reported in this communication; XRD, TGA/DTA and SEM. The upshot of XRD proposes a semi-crystalline nature of synthesized nanocomposite. The crystalline character of the nanocomposite enhances with an increasing doping concentration of the prepared nanoparticles. Thermal analysis suggests the degradation pattern of the polymer nanocomposite material and represents that thermal stability improves as the silver nanoparticles are added. The SEM micrograph reveals a uniform surface with a well dispersed nanoparticle in the polymer matrix.

Published: June 2022

In the modern world researchers caught the attraction towards spinal ferrites. The current work is based on spinel ferrites having formula Ni0.5Co0.5CexFe2-xO4 where (x = 0.0, 0.05, 0.1, 0.15, 0.2) Prepared by co-precipitation method. The confirmation of spinal ferrite structure was done through XRD analysis. The crystallite size was found to be in the range of 8 to 11 nm. Lattice perimeter is observe to obey the increasing trend due to replacement of larger ionic radii of cerium with smaller ionic radii of iron.  Koop's phenomenological theory, Maxwell–Wagner interfacial polarization and Vegard’s law is used to explain the behavior of lattice constant. The electrical properties of prepared ferrites were revealed by impedance analyzer. Various parameters like real and imaginary parts of dialectic constant, impedance and modulus was determined. In the frequency range of 1 to 3 GHz the detailed electrical inspection was done. During the electrode polarization the effect of grains on the increasing substitution of cerium was analyzed through real and imaginary parts of electrical modulus M' and M". In the frequency range of 3 GHz the value of M' is 2.1934 × 10-1 to 2.6581 × 10-1 and the value of M" is from 4.67 × 10-3 to 3.538 × 10-3. AC conductivity spectra shows a non-Debye relaxation behavior and it dependents of conductivity on frequency. The observed dielectric constant, dialectic loss and tangent loss are found to be decreasing with the increase in frequency. The investigation shows that real and imaginary impedance Z' and Z" was found to be decreasing on lower frequencies and on higher frequencies all the curves merge with each other. The value of Z' and Z" at 3GHz frequency is in the range of 8.02 × 10-3 to 0.6073 and 3.7641 × 101 to 4.5617 ×101 respectively. Increase in frequency increases the AC conductivity. The applications of prepared nanoparticles are suggested in high frequency devices because of the splendid dielectric properties of these particles.
Synthesis and Characterization of Rare Earth (Ce) Substituted Magnesium Ferrite MgCe0.1Fe1.9O4 and Banana Peel BPMgCe0.1Fe1.9O4
Authors: Ur Rehman Atiq , Mukhtar Ahmad
Published: June 2022

In this study, a composite of cerium doped magnesium ferrite (MgCexFe2-xO4 , x= 0.1) and banana peel powder was prepared by hydrothermal method.  Crystal structure and phase identification, chemical bonding, and magnetic properties were characterized by X-ray diffraction (XRD), Fourier transform infrared (FTIR) and vibrating sample magnetometery (VSM), respectively. XRD results reveal that the prepared ferrite exhibits single phase face centered cubic (fcc) structure having no impurity in the sample. Addition of banana peel powder has no effect on the crystal structure. The values of structural parameters greatly match with the earlier reported values for the same structure. FTIR results clearly indicate that the prepared ferrite is spinel and have well defined vibrational and stretching peaks due to different molecules present in the compound. Coercivity values for both ferrite and composite materials are found to be a few hundred Oersted which confirm the soft magnetic nature of this ferrite. The observed parameters show that the prepared composite may find technological application for microwave absorption and multi-layer chip inductors.

Published: June 2022

The current research focuses on the fabrication and characterization of barium tin oxide antiperovskite oxide Ba3SnO. BaO and Sn2O were used as precursors to synthesise the Ba3SnO by using solid state ceramic method. Co ion has been implanted using Pelletron Accelerator with different doses 1013, 5×1013, 1014 ions/cm2. The study includes the investigations of penetration depth range of Co ions in the target material, structural, surface morphology, verification of elemental composition, and band gap energy by using the characterization techniques SRIM, XRD, SEM, EDX, FTIR, and UV-Vis spectroscopy respectively. Phase identification of desired material assures by XRD. SEM results showed that the rough and sharp rod shape varies into a very smooth and fine granular shape by ion implantation. EDX plots confirm the existence of basic elements like Ba, Sn, Co and O. The FTIR identify the unknown material and components which confirmed the formation of B3SnO and incorporation of Co ions. UV-Vis spectroscopy results revealed that increasing the implanted ion dose causes a slight increase in band gap energy from 2.61 to 2.88 of this material. The obtained results allow us to conclude that the prepared sample contains a fine structure with no impurity. Therefore, we can say that this process is ideal for obtaining fine structured Ba3SnO.

Internet of Things (IoT) is a system that connects computing devices including phones, sensor, mechanical machines and other items over a network allowing them to exchange data and perform tasks without human interaction. It has altered the means by which connected devices interact and communicate, facilitating smarter and more convenient applications. As a result of their technological specifications, these devices are considered power constrained, as they lack battery sources. Therefore, they require a suitable underlying technology that considers power constraints and fulfills other IoT application requirements including long-range communication and low cost. Low Power Wide Area Network (LPWAN) is a communication technology that is gaining increasing popularity, as it provides low-rate long-range communication suitable for IoT applications. This research uses simulation to evaluate the performance of LoRa and Sigfox as the leading LPWAN technologies. The simulation evaluates collision, packet error rate and spectrum using different values for channel bandwidth. It also examines the impact of the number of IoT devices on network performance. Results reveal that Sigfox has less collisions and packet error rate compared to LoRa. They also show that in general, increasing the number of devices leads to increasing collision and packet error rate. Utilizing larger bandwidth provides more available slots and therefore reducing collision.

Published: June 2022

Esse estudo pretende analisar um recorte do filme brasileiro Bacurau (2019),  com a finalidade de compreender de que maneira a forma e o conteúdo dessa obra podem ser interpretados e relacionados a alguns princípios da teoria épico-brechtiana. Partindo do princípio de que o teatro épico-brechtiano é um poderoso agente para as transformações sociais, a postura que deve ser adotada pelos espectadores do teatro épico é a do distanciamento. Assim, para manter o espectador distanciado e, portanto, ativo, é necessário lançar mão de alguns recursos, no caso desse estudo, nos interessa compreender o gestus épico-brechtiano e como esse conceito pode ser observado para a construção do distanciamento em uma obra cinematográfica.

Invisibilidade Interseccional, Superinclusão e Direitos Humanos
Authors: Pagliaro Heitor , De Oliveira Lorena
Published: June 2022

Este artigo desenvolve a ideia de que uma concepção universalista de direitos humanos, ao promover a superinclusão, deflagra a invisibilidade interseccional, no que diz respeito às diversas desigualdades sofridas pelas mulheres. A interseccionalidade tem uma relação direta com a interação entre os marcadores sociais de diferença, fornecendo uma perspectiva teórica e metodológica que permite compreender a convergência de opressões conjugadas que estruturam determinados sistemas de discriminação. Pensando assim, a ideia de interseccionalidade pode oferecer melhores ferramentas para promoção de igualdade do que a noção de unidade, própria do universalismo da superinclusão, pois cria condições de visibilidade aos diferentes eixos de opressão nos quais as mulheres se encontram. A problemática de pesquisa é enfrentada por meio da revisão bibliográfica crítica, especialmente da literatura sobre feminismo interseccional, baseando-se principalmente no pensamento de Kimberlé Crenshaw e Grada Kilomba.

Mapeamento de dolinas utilizando Modelo Digital de Elevação na Borda Ocidental do Chapadão Central – Oeste da Bahia, Brasil
Authors: Bispo da Silva Gisele , Soares Cherem Luis Felipe , Nunes Amaral Ana Karolyna
Published: June 2022

As dolinas são feições superficiais indicativas do sistema cárstico que conectam a drenagem superficial à subterrânea. O sistema cárstico desenvolve-se sobretudo pela ação da dissolução em subsuperfície, com a interação da água com as rochas carbonáticas e algumas rochas siliciclásticas. Na porção Ocidental do Chapadão Central – Oeste da Bahia, desenvolvido sobre os arenitos do Grupo Urucuia, ocorrem essas depressões fechadas, que podem estar ligadas ao sistema cárstico de dissolução do arenito. O objetivo é mapear as dolinas que ocorrem sobre essa chapada a partir de um algoritmo já consolidado para esse fim e convalidando com as dolinas fotointerpretadas. Foram identificadas 8.187 depressões pelo método automático, 5.701 depressões depois de feita a limpeza topológica na rede de drenagem, 202 depois de ajustado o tamanho mínimo de 16.200 m² para 80.000 m² e fotointerpretadas 109 dolinas. Das 202 depressões mapeadas automaticamente, 43 correspondem a dolinas dispersas na chapada e não identificadas na fotointerpretação e 50 correspondem a erros ocasionados pela alta rugosidade no MDE. O mapeamento automático mostrou-se efetivo quando os critérios do algoritmo foram ajustados.

Doctor of Physical Therapy students’ clinical reasoning readiness and confidence treating with telehealth: a United States survey
Authors: F. Campbell Derrick , Brismée Jean-Michel , Allen Brad , Hooper Troy L. , Domenech Manuel A. , Manella Kathleen J.
Published: June 2022

Purpose: Telehealth has an emerging footprint on entry-level physical therapy programs. Students’ readiness for clinical reasoning with virtual versus traditional face-to-face treatment remains unknown. The purpose of this study was to evaluate Doctor of Physical Therapy (DPT) students’ preparedness for clinical experiences with and without telehealth.
Methods: A descriptive and exploratory cross-sectional survey was employed, with a voluntary convenience sample of 211 second- and third-year university DPT students during Fall 2020 clinical experiences. Descriptive and inferential statistics evaluated differences in DPT students’ (1) Physical Therapist Self-Efficacy (PTSE) scale scores, (2) confidence with treating initial and subsequent same-patient visits, and (3) final Clinical Performance Instrument (CPI) clinical reasoning and summative scores during clinical experiences with and without telehealth.
Results: Telehealth availability was 40.3%, with 16.6% of DPT students reporting participation. Most students reported being comfortable (39.3%) or neutral (32.2%) using telehealth. DPT students’ confidence level using telehealth to treat was 74% on initial and 97% on subsequent same-patient visits. Mean PTSE scores were significantly lower during clinical experiences with telehealth (13.1) compared to traditional experiences (15.1) (P <.001) and for integrated (second-year) (14.1) compared to terminal (third-year) clinical experiences (15.5) (P <.001). For traditional experiences, weak positive associations were demonstrated between PTSE and CPI scores. There were no significant differences for CPI scores between telehealth and traditional experiences.
Conclusion: While entry-level DPT programs continue to establish best practice for telehealth education, current trends in academic curriculum seem to prepare students’ clinical reasoning readiness for clinical experiences. The PTSE could be used to identify outlier students requiring additional mentoring during traditional and telehealth clinical experiences.

World Health Organization (WHO) mendefinisikan remaja sebagai mereka yang berada pada tahap transisi antara masa kanak-kanak dan dewasa, dengan periode usia antara 10 sampai 19 tahun. Masa remaja merupakan periode penting dalam rentang kehidupan manusia karena pada masa peralihan ini remaja merasakan adanya perubahan yang terjadi pada dirinya sendiri seperti perubahan pada fisik, kognitif, dan sosial emosional. Slavin (2009) mengatakan bahwa remaja mengalami kegoncangan emosi negatif yang disebabkan oleh tekanan-tekanan dan ketegangan dalam mencapai kematangan fisik dan sosial. Remaja yang memiliki konsep diri negatif biasanya cenderung menjadi korban bullying (Usman, 2013). Hal tersebut dikarenakan remaja dengan konsep diri negatif akan cenderung menarik diri dari lingkungannya (SEJIWA, 2008). Seorang remaja diharapkan mampu serta dapat mengontrol perasaan mereka dan mampu untuk mengendalikan serta dapat memahami gejolak emosi sehingga akan tercapai kondisi emosional dan mudah menyesuaikan diri dengan lingkungan, dengan begitu remaja akan mampu menyelesaikan tugas-tugas perkembangan dengan baik (Paramitasari & Alfian, 2012). Sasaran kegiatan ini adalah remaja. Program pengabdian masyarakat ini meliputi beberapa tahapan yaitu dimulai dengan menyusun konsep pelaksanaan kegiatan, membuat video animasi, mengupload video animasi ke media sosial, dan membuat laporan kegiatan. Kegiatan ini diharapkan mampu mencegah terjadinya perilaku bullying pada remaja.

Chlorpyrifos has been considered as one of the most frequently used organophosphorus insecticides in agriculture worldwide. There has been considerable public concern regarding its neurotoxicity and its genotoxicity on mammals, aquatic organisms, and other non-target species. In this study 23 bacterial isolated strains from different origins were tested for their ability to resist and subsequently degrade chlorpyrifos (CP). Seven of these strains showed a resistance to up to 1000mg/L CP on solid minimal mineral salt medium (MMSM) and the strain Pseudomonas sp. B5-2 was selected for further analysis after a selection on liquid MMSM. The effect of different concentrations of CP on the growth of the selected strain was tested, and 200 mg/L was the highest concentration that supports its growth. The ability of the selected strain to eliminate CP was investigated in the presence and in the absence of glucose as an external carbon source. The results showed that the strain utilized chlorpyrifos (200 mg/L) as the sole source of carbon better than in presence of an external carbon source (glucose) with an elimination rate of 67.06% and 14.61%, respectively. These results highlight the potential of this bacterium to be used in the cleanup of contaminated pesticide waste in the environment.

In this study, a novel series of heterocyclic compounds containing pyrazoline nucleus has been synthesized. The compounds were synthesized in two steps. Chalcone was synthesized in the first step by Claisen-Schmidt reaction, using 1-acetylnaphthalene and p-nitrobenzaldehyde as reactants. In the second step, the chalcone was cyclized in an acidic medium with some hydrazine derivatives to form pyrazolines. All the compounds were characterized by physical, chromatographic, spectroscopic, and elemental analysis and evaluated in vitro for antimicrobial activity against nine microorganisms by cup plate method. The minimum inhibitory concentration of all the compounds was determined by tube dilution method. All the compounds exhibited higher antibacterial activity as compared to the antifungal activity. Compound 5g (3-Naphthalen-1-yl-1-(2-nitro-phenyl)-5-(4-nitro-phenyl)-4, 5-dihydro-1H-pyrazole)exhibited maximum antibacterial and antifungal activity and may be designated as the most potent member of the series, with 2-nitrophenyl group at N-1 position of the 2-pyrazoline ring.

Objective: Aim of current study is to determine the comparison of death rates among diabetic and non diabetic patients with coronavirus disease. Study Design: Retrospective/Observational study Place and Duration: The study was conducted at Diabetes Hospital, Peshawar and Medicine department of Avicenna Medical & Dental College and Hospital, Lahore for the duration of six months from December 2020 to May 2021. Methods: There were one hundred and fifty patients of both genders either diabetic or non diabetic with ages 20-75 years were included in this study. After receiving informed written agreement, the demographics of enrolled patients were recorded, including age, gender, BMI, and socio-economic status. All patients who had a confirmed diagnosis of COVID-19, with polymerase chain reaction testing, were included in the study. Outcomes among all patients in terms of mortality rate were recorded among all cases. We used SPSS 21.version to analyze complete data. Results: Among 150 patients, 60 (40%) cases were diabetic and 90 (60%) were non-diabetic. Mean age of the patients was 35.14±11.44 years and mean BMI 29.31±8.55 kg/m2. We found most of the cases 85 (56.7%) were males and 65 (43.3%) were females. 95 (63.3%) patients had poor socioeconomic status. Most common comorbidity was hypertension found in 68 (45.3%) cases followed by cardiovascular disease in 45 (30%) cases. Frequency of mortality in diabetic patients was significantly higher found in 35 (58.3%) cases as compared to non diabetic patients in 27 (30%) cases with p value <0.005. Conclusion: Diabetic individuals with COVID-19 showed a considerably greater death rate compared to non-diabetics. As a result, diabetes patients must be educated about the risks of infection-related hyperglycemia, the necessity of following sick-day policies, and the consequences of social isolation.
