Published: January 2022

New lacunary Keggin type polyoxometalate salts (Ni2.5PMo11
M(H2O)O39/M = Co, Fe, Cu, Zn), were synthesized using the inorganic condensation method. X-ray diffraction and infrared spectroscopy results showed that the Keggin structure of the salts was preserved. The thermal stability was checked by differential scanning calorimetry coupled with thermogravimetric analysis showing that the thermal resistance was significantly improved by the incorporation of the metals into polyoxometalates. Proton and molybdenum substitution respectively by nickel and cobalt, iron, copper and zinc metals induced a positive effect on the crystallographic configuration of the prepared salts allowing them a better thermal resistance (up to 580 °C). Cyclic voltammetry revealed an interesting electrochemical property of synthesized samples, especially for Ni2.5PMo11Zn(H2O)O39 sample in which the presence of zinc greatly boosted the redox behavior.

Published: January 2022

In order to develop novel materials based on rare earth (RE) boride and/or transition metals, phase equilibria and thermodynamic information of the RE–B based alloys are indispensable. On the basis of experimental phase equilibria and thermodynamic properties, thermodynamic assessments of the RE–B (RE = La, Sm, Gd and Tb) binary systems were carried out by the CALPHAD (Calculation of Phase Diagram) method. Self-consistent parameters of the RE–B (RE = La, Sm, Gd and Tb) binary systems were obtained, which can be used to reproduce well the experimental data. Furthermore, in combination with the previous assessments of the RE–B binary systems in the literature, phase equilibria and thermodynamic properties of the RE–B (RE = La, Ce, Pr, Nd, Sm, Gd, Tb, Dy, Ho, Er, Tm and Lu) binary systems are discussed systematically. The tendency of phase equilibria and thermodynamic information as a function of RE atomic number is demonstrated. In general, the enthalpy of mixing of liquid RE–B alloys and the enthalpy of formation of the RE–B intermetallic compounds become more and more negative with the increase in RE atomic number (except for La, Ce, Pr and Nd), while the phase transition temperatures for the RE–B intermetallic compounds increase gradually.
Semantic analysis and frequency effects of conceptual metaphors of emotions in Latin. From a corpus-based approach to a dictionary of Latin metaphors
Authors: Buccheri Alessandro , De Felice Irene , Fedriani Chiara , Short William M.
Published: January 2022

This article presents the main results of a corpus-based analysis of the metaphorical expression of emotions in Latin and a new resource specifically designed to facilitate such large-scale study of conceptual metaphors, theLexicon Translaticium Latinum. The first part of the paper provides quantitative and qualitative evidence about the types of metaphors used by Roman writers to express four basic emotions: fear, anger, love, and hate. Our research takes a corpus-based and target-oriented approach, analyzing all occurrences of the main lexemes denoting these emotions in Latin texts dating between the third century BCE and the second century CE. The results demonstrate the highly embodied nature of the metaphors used by Latin authors to make sense of (and express linguistically) their experiences of fear, anger, love, and hate. Moreover, the differences in the usage of the metaphorical patterns across the four semantic fields, in terms of type and frequency, correlate with the different physiological reactions provoked by the four emotions we examined. In the second part of the paper, we present theLexicon Translaticium Latinum, an open-access, digital dictionary of Latin metaphors, currently under development. It facilitates large-scale analyses of highly conventionalized metaphoric patterns that organize meanings throughout Latin, at the same time allowing the kinds of relations that subsist between different types of metaphors to be captured and encoded in machine-readable formats.
The complementary distribution betweennēandnōnrevisited: a semantic approach to wish and result clauses
Authors: Demonie Anne-Li
Published: January 2022

This paper revisits the well-established complementary distribution between the sentential negators in Classical Latin,nēandnōn. It will be shown that in wish and result clauses these negators alternate in a seemingly free manner, which would violate the complementary distribution in its strictest sense. However, this paper argues that the negators can be clearly differentiated semantically, and that there is as such no overlap between their functions. Building on Mellet (1992. L’alternancene/nonen latin Classique.L’Information Grammaticale55.28–32), the alternation in wish and result clauses is discussed, and it is demonstrated that the choice of negator depends on the presence of the subjunctive mood and the presence or absence of epistemic certainty:nēis the negator which is incompatible with epistemic certainty, whereasnōnis the negator which is compatible with it.

Authors: Martines Gennaro , Tomasicchio Giovanni , Picciariello Arcangelo , Dibra Rigers , Trigiante Giuseppe , Lantone Giuliano , Altomare Donato Francesco
Published: January 2022

Background

A dreaded complication of laparoscopic sleeve gastrectomy (LSG) is suture leak. The study aimed to assess the efficacy of the nebulized comonomer Glubran 2® (N-butyl-cyanoacrylate + metacrylosysolfolane) applied to the LSG staple line.

Methods

A propensity-matched comparison analysis was conducted in 125 patients undergoing LSG between 2017 and 2019. Groups included those treated with Glubran® (group 1, n = 70) and those without Glubran® treatment (group 2, n = 55).

Results

There were differences in the mean body mass index (44.4 vs 43 kg/m2; P < 0.05) between the groups. There was a non-significant increase in the operative time for group 1 compared with group 2 (97 ± 8 vs 93.8 ± 10.7 min; P = 0.07), with a greater amount of estimated blood loss (94.5 mL vs 87.8; P < 0.01). There were more severe complications in group 2 over group 1 cases (8 vs 0%; P < 0.05), although postoperative bleeding did not differ between the two groups (1.4 vs 5.4%). There were no postoperative leaks in group 1 patients, but there were two leaks in group 2 cases with an increased length of hospital stay in patients with a leak.

Conclusion

Glubran® LSG support may reduce leak risk without increasing operating time.
The perspectives of broadband metasurfaces and photo-electric tweezer applications

Published: January 2022

With strong demands of real-time monitoring of biomolecules or environmental pollutants, overcoming technical hurdles on control and detection of freely diffusive nanoscale objects become a question of issue to solve in a variety of research fields. Most existing optical techniques inevitably require labeling to the target material, which sometimes denature the measuring biomaterials. For highly efficient real-time monitoring without complicated pretreatment or labeling, many successes in development of label-free or non-destructive detection techniques via increased sensitivity were accomplished by the additional structures. Metasurface-based two-dimensional photonic/electric devices have recently represented extraordinary performances in both manipulation and sensing for various small particles and biochemical species, repeatedly overcoming the limit of detection achieved right before. In parallel, various metasurface-based devices were also introduced promoting transportation of targets into optical hotspot sites, overcoming diffusion limits. We noted this point, therefore, reviewed two major research fields such as metasurface-assisted material sensing and transportation technologies that have contributed to present prospective sensing technologies, then showed perspective views on how great synergy can be created when two technologies are cleverly integrated. Recently, a trend of conceptual merging of optical detection and transporting schemes beyond both diffraction limit and diffusion limit leads to a creation of exceptional performance in molecular detections. In this review, the trends of the latest technologies accomplishing this purpose by hybridization of various composite materials and functional metasurfaces will be introduced.
Progress of albumin-polymer conjugates as efficient drug carriers
Authors: Raveendran Radhika , Dan Xu You , Joshi Nidhi , Stenzel Martina H.
Published: January 2022

Albumin is a protein that has garnered wide attention in nanoparticle-based drug delivery of cancer therapeutics due to its natural abundance and unique cancer-targeting ability. The propensity of albumin to naturally accumulate in tumours, further augmented by the incorporation of targeting ligands, has made the field of albumin-polymer conjugate development a much pursued one. Polymerization techniques such as RAFT and ATRP have paved the path to incorporate various polymers in the design of albumin-polymer hybrids, indicating the advancement of the field since the first instance of PEGylated albumin in 1977. The synergistic combination of albumin and polymer endows manifold features to these macromolecular hybrids to evolve as next generation therapeutics. The current review is successive to our previously published review on drug delivery vehicles based on albumin-polymer conjugates and aims to provide an update on the progress of albumin-polymer conjugates. This review also highlights the alternative of exploring albumin-polymer conjugates formed via supramolecular, non-covalent interactions. Albumin-based supramolecular polymer systems provide a versatile platform for functionalization, thereby, holding great potential in enhancing cytotoxicity and controlled delivery of therapeutic agents.
Psychological interventions in preventing chronicity of sub-acute back pain: a systematic review
Authors: Orenius Tage , Silén Esko , Nuortimo Antti , Ristolainen Leena
Published: January 2022

Objectives

There is scarce information on preventive psychological and behavioural methods applicable to sub-acute (4–12 weeks) back pain, a precursor to chronic back pain. We conducted a systematic literature review of the efficacy of psychological interventions in preventing chronicity of sub-acute back pain.

Methods

A systematic literature search in CINAHL, CENTRAL, MEDLINE, PubMed®, PsychINFO, Scopus and Web of Science databases.

Results

From a total of 271 records, only three studies met the eligibility criteria. In two of the reviewed studies, the interventions had an insignificant preventive impact on the chronification of back pain. In one study the CBT intervention proved promising in preventing back pain related disability. None of the studies reported a significant impact on pain intensity at follow-up.

Conclusions

The psychological interventions did not impact pain outcomes. There is a disproportion between novel knowledge on psychological factors involved in the transition to chronic pain and corresponding preventive treatments. Additional studies on psychological interventions on sub-acute back pain prevention are highly warranted due to the enormous burden that back pain creates when it becomes chronic. The research project has the ethical approval of the Research Ethical Committee at Helsinki University Hospital, HUS/2435/2017.
Simultaneous PIV and shadowgraph measurements of thermo-electrohydrodynamic convection in a differentially heated annulus
Authors: Szabo Peter S. B. , Meyer Antoine , Meier Martin , Motuz Vasyl , Sliavin Yaraslau , Egbers Christoph
Published: January 2022

Convection in a silicone oil with a temperature dependant fluid property is investigated experimentally in a differentially heated cylindrical annulus. A convective flow is induced by terrestrial gravity in axial direction and combined with an electrical tension applied between both cylinders to induce thermo-electrohydrodynamic convection. To capture the evolving velocity and temperature fields a novel combination of simultaneous PIV and shadowgraph technique is utilized. Results reveal azimuthal modes with cold and hot jets from inner and outer cylinder that are referred to the electric tension. The lack of information in the shadowgraph pictures were recovered by the PIV technique providing a deeper understanding in the nature of the development of the azimuthal mode number and the surrounding axial flow of natural convection. In addition, the results provide a robust framework in the capability of combining both techniques to investigate complex flow patterns that are non-axisymmetric.

In this paper, a novel series of ester-functionalized cationic Gemini surfactants with amide groups (abbreviated as C
m
-(BAE)-C
m
(m = 12, 14, 16)) were synthesized and their surface tension as well as the thermodynamic surface parameters were determined with conductivity and fluorescence measurements, respectively. The structures of these Gemini surfactants were characterized by FT-IR, 1H NMR, and MS. The Krafft points of the three surfactants are below 0 °C, indicating better water solubility. The critical micelle concentration (CMC) of these surfactants decreases with the increase in the length of hydrophobic chain. The micellization process of these surfactants was found to be entropy-driven. The polar functional ester groups in the spacer form hydrogen bonds with water molecules, which increases the solubility of these Gemini surfactants in aqueous systems, facilitates the aggregation of their monomers and improves the stability of their micelles.
Oryza sativa plant extract in 15% hydrochloric acid as a green corrosion inhibitor on the surface of stainless steel 410
Authors: Bhardwaj Nishant , Sharma Pooja , Kumar Vineet
Published: January 2022

Fifteen percent hydrochloric acid (HCl) solutions are used for some cleaning processes in the petroleum industry. The use of such a corrosive medium is mainly responsible for the corrosion of the stainless steel (SS-410) vessels and pipings. In this study, the corrosion inhibiting properties of Oryza sativa plant extract (OSPE) from agricultural residues are investigated on SS-410 steel surfaces in a 15% HCl medium. Gravimetric analysis showed a maximum corrosion inhibition of 91.92% with 4 g/L OSPE in 15% HCl solution. Scanning electron microscopy (SEM), atomic force microscopy (AFM), and X-ray diffraction studies confirmed the adsorption of OSPE on the SS-410 surface. The adsorption of OSPE on SS-410 followed the Langmuir adsorption isotherm, indicating the formation of a monolayer on the SS-410 surface. The theoretical study confirmed that the anticorrosive effect could be mainly related to the phytochemical 9,12,15-octadecatrienoic acid 2,3-dihydroxypropyl ester. Consequently, the OSPE containing this phytochemical shows an anticorrosive behavior on the SS-410 surface in an acidic 15% HCl solution.
The “ferros” of MAPbI3: ferroelectricity, ferroelasticity and its crystallographic foundations in hybrid halide perovskites
Authors: Breternitz Joachim
Published: January 2022

Hybrid halide perovskites have been identified as an important novel class of photovoltaic absorbers and have proven their great potential with ever record-breaking efficiencies. Some of the more fundamental properties of halide perovskites, however, still are to be properly understood. The ongoing debate as to whether ferroelectricity and/or ferroelasticity play a role in these materials is just one example for this. Herein, I aim to make these phenomena more approachable to the wider research community and elucidate the foundations and consequences of these phenomena.
Cultivar la excepción: monstruosidad discursiva en Nietzsche
Authors: Zengotita Alonso
Published: January 2022

El tema de la construcción discursiva en Nietzsche se ha trabajado numerosas veces, pero prácticamente de modo exclusivo desde el lugar del lenguaje, articulado a las nociones de verdad, metáfora, memoria, mentira, conciencia –entre otros.

Sin tomar de modo central a la noción de lenguaje, en el presente artículo se buscará trabajar la forma en que la discursividad en Nietzsche se construye articulándola al modo en que la figura del genio es pensada. Dicho de otro modo, así como el genio aparecerá como excepcionalidad monstruosa, se buscará dar cuenta de cómo la discursividad nietzscheana presenta la misma caracterización frente a la epistemología canónica –aquella que Nietzsche busca confrontar. En orden de realizar esto, en primer lugar se desarrollará cómo Nietzsche piensa al genio como excepción, para luego dar cuenta del lugar diferencial que dicha excepción ocupa respecto de la perspectiva biológica canónica con la que confronta –aquella de Darwin. Desde aquí, desplegando la modalidad de construcción discursiva nietzscheana, se buscará fundamentar cómo y desde qué dinámica ese discurso aparece como monstruosidad excepcional respecto a la epistemología predominante de su época.
Humores poéticos: aproximaciones al humor en la poesía española de las últimas décadas
Authors: Leuci Verónica
Published: January 2022

El trabajo propone aproximarse al controvertido cruce entre humor y poesía, un enlace polémico que a menudo ha sido omitido o desvalorizado en las aproximaciones teóricas al género, que lo vinculan más bien con el patetismo, la solemnidad o la gravedad, a partir probablemente de malas lecturas del Romanticismo. En cambio, se plantea un acercamiento a algunas de las voces más importantes de la escena poética española, a partir de las décadas del 80 y 90, como Luis A. de Cuenca, Luis García  Montero, Roger Wolfe y Karmelo Iribarren. Ellos plantean en sus obras diversas manifestaciones risibles, presentando humores poéticos que apuntan a búsquedas diversas, y que van de la risa a la sonrisa, de la crítica a la ternura y del desagrado a la complacencia para realizar una lectura a contrapelo de la literatura y de la realidad, a través de la lupa descarnada y la lucidez que aporta el humor.
La Vida que inútilmente se consuma en la llama. Imagen, Gesto y Política: Giorgio Agamben y Guy Debord
Authors: Karmy Rodrigo
Published: January 2022

El presente ensayo muestra la influencia del trabajo de Guy Debord en el pensamiento de Giorgio Agamben, en particular, en lo que se refiere a uno de los núcleos de su pensamiento, esto es, la diferencia entre “imagen” y “gesto”. Para ello, se recurrirá a tres momentos de su trabajo, partiendo por las “Glosas a los Comentarios de la Sociedad del espectáculo” escritas en 1993, pasando por “El Reino y la Gloria” del año 2007 y terminando en “El Uso de los cuerpos” de 2014. En los tres momentos existen breves referencias a Debord que, sin embargo, conducirán a Agamben a la cuestión del “gesto” o, lo que es igual, a la forma-de-vida.
La museificación de la obra de arte y de la ciudad. Un ensayo sobre la figura del Museo en el pensamiento de Giorgio Agamben y Guy Debord
Authors: Hernández Martínez Cuauhtémoc Nattahí
Published: January 2022

El museo, en la perspectiva crítica tanto de Guy Debord como de Giorgio Agamben, es señalado como aquel espacio donde la obra de arte se convierte en un objeto de mera contemplación y en un objeto desvitalizado, en la medida en que pierde su conexión con el mundo vivo y el espacio común a todos los hombres. Es decir, es señalado como un espacio que termina “museificando” las obras de arte, esto es, desvitalizándolas y vaciándolas de sentido, en la medida en que quedan separadas de la vida. Lo que haremos en el ensayo es explorar los alcances y el sentido de esta crítica al museo como esfera separada que mantiene el abismo entre el arte y la vida. Así como analizar la manera en que este rechazo del museo se transformará, a mediados de los años noventa, en una perspectiva de crítica radical de la museificación que, a juicio de Agamben, es una de las tendencias que caracteriza y define a las sociedades del espectáculo consumado. Una tendencia que atañe a la ciudad, en principio, y que supone un empobrecimiento de la experiencia.

The Sensory and Motor Components of the Cortical Hierarchy Are Coupled to the Rhythm of the Stomach during Rest
Authors: Rebollo Ignacio , Tallon-Baudry Catherine
Published: January 2022

Bodily rhythms appear as novel scaffolding mechanisms orchestrating the spatiotemporal organization of spontaneous brain activity. Here, we follow-up on the discovery of the gastric resting-state network (Rebollo et al., 2018), composed of brain regions in which the fMRI signal is phase-synchronized to the slow (0.05 Hz) electrical rhythm of the stomach. Using a larger sample size (n= 63 human participants, both genders), we further characterize the anatomy and effect sizes of gastric-brain coupling across resting-state networks, a fine grained cortical parcellation, as well as along the main gradients of cortical organization. Most (67%) of the gastric network is included in the somato-motor-auditory (38%) and visual (29%) resting state networks (RSNs). Gastric brain coupling also occurs in the granular insula and, to a lesser extent, in the piriform cortex. Thus, all sensory and motor cortices corresponding to both exteroceptive and interoceptive modalities are coupled to the gastric rhythm during rest. Conversely, little gastric-brain coupling occurs in cognitive networks and transmodal regions. These results suggest not only that gastric rhythm and sensory-motor processes are likely to interact, but also that gastric-brain coupling might be a mechanism of sensory and motor integration that mostly bypasses cognition, complementing the classical hierarchical organization of the human brain.

SIGNIFICANCE STATEMENTWhile there is growing interest for brain-body communication in general and brain-viscera communication in particular, little is known about how the brain interacts with the gastric rhythm, the slow electrical rhythm continuously produced in the stomach. Here, we show in human participants at rest that the gastric network, composed of brain regions synchronized with delays to the gastric rhythm, includes all motor and sensory (vision, audition, touch and interoception, olfaction) regions, but only few of the transmodal regions associated with higher-level cognition. Such results prompt for a reconsideration of the classical view of cortical organization, where the different sensory modalities are considered as relatively independent modules.
Frequency Shapes the Quality of Tactile Percepts Evoked through Electrical Stimulation of the Nerves

Published: January 2022

Electrical stimulation of the peripheral nerves of human participants provides a unique opportunity to study the neural determinants of perceptual quality using a causal manipulation. A major challenge in the study of neural coding of touch has been to isolate the role of spike timing—at the scale of milliseconds or tens of milliseconds—in shaping the sensory experience. In the present study, we address this question by systematically varying the pulse frequency (PF) of electrical stimulation pulse trains delivered to the peripheral nerves of seven participants with upper and lower extremity limb loss via chronically implanted neural interfaces. We find that increases in PF lead to systematic increases in perceived frequency, up to ∼50 Hz, at which point further changes in PF have little to no impact on sensory quality. Above this transition frequency, ratings of perceived frequency level off, the ability to discriminate changes in PF is abolished, and verbal descriptors selected to characterize the sensation change abruptly. We conclude that sensation quality is shaped by temporal patterns of neural activation, even if these patterns are imposed on a fixed neural population, but this temporal patterning can only be resolved up to ∼50 Hz. These findings highlight the importance of spike timing in shaping the quality of a sensation and will contribute to the development of encoding strategies for conveying touch feedback through bionic hands and feet.

SIGNIFICANCE STATEMENTA major challenge in the study of neural coding of touch has been to understand how temporal patterns in neuronal responses shape the sensory experience. We address this question by varying the pulse frequency (PF) of electrical pulse trains delivered through implanted nerve interfaces in seven amputees. We concomitantly vary pulse width to separate the effect of changing PF on sensory quality from its effect on perceived magnitude. We find that increases in PF lead to increases in perceived frequency, a qualitative dimension, up to ∼50 Hz, beyond which changes in PF have little impact on quality. We conclude that temporal patterning in the neuronal response can shape quality and discuss the implications for restoring touch via neural interfaces.

Authors: Asmad Ilyana Najwa Aiza , Mubarak Ali Al-Fahim , Jailani Nik Intan Syahiddatul Ilani
Published: January 2022

Identical code fragments in different locations are recognized as code clones. There are four native terminologies of code clones concluded as Type-1, Type-2, Type-3 and Type-4. Code clones can be identified using various approaches and models. Generic Code Clone Detection (GCCD) model was created to detect all four terminologies of code clones through five processes. A prototype has been developed to detect code clones in Java programming language that starts with Pre-processing Transformation, Parameterization, Categorization and ends with the Match Detection process. Hence, this work targeted to enhance the prototype using a GCCD model to identify all clone types in Python language. Enhancements are done in the Pre-processing process and parameterization process of the GCCD model to fit the Python language criteria. Results are improved by finding the best constant value and suitable weightage according to Python language. Proposed enhancement results of the Python language clone detection in GCCD model imply that Public as the weightage indicator and def as the best constant value.
Characterising of Plant Cover Evolution in the Aurès Region (Eastern Algeria)
Authors: Malki Hamana , Bezzih Houda , Aissi Abdeljalil
Published: January 2022

A better understanding of the evolution of vegetation cover is a major concern for countries where mountain ecosystems are undergoing severe degradation. Mediterranean woodland ecosystems in general and those of Algeria in particular, are suffering from numerous types of degradation, be they climatic or anthropogenic. For this reason, and to have a better understanding of this issue and how to deal with it, we decided to carry out a study in the Aures Mountains (eastern Algeria), where the phenomenon of degradation has a direct impact on natural resources. The evolution of the vegetation cover in the region was analysed, using remote sensing data (Landsat-type satellite images) over a 33-year period (1984-2017). A notably pronounced regressive evolution of the plant cover was attributed both to the phenomena of climate change and dieback (which particularly affected the cedar groves) and to the anthropogenic pressure (manifest in fires, overgrazing, illegal cutting, etc.) exerted on the vegetation as a whole. It will therefore become more than necessary to take measures to protect and preserve the region's rich ecological heritage.

Published: January 2022

Healthcare settings, including nuclear medicine (NM) departments, promptly adjusted their standard operating procedures to cope with the unprecedented crisis caused by coronavirus disease 19 (COVID-19) pandemic. Nuclear thyroidology has adopted changes and predicated on a careful risk–benefit analysis, in order to prevent a potential spread of the virus while being at the same time effective, safe and preserving their quality of essential services. Since most thyroid nodules (TNs) are benign, and malignant neoplasms are characterized by an indolent natural history, it is generally safe to delay diagnostic and therapeutic procedures. In this respect, the main adjustments that nuclear thyroidology has adopted are summarized into the following: general workplace adjustments including remote work for NM staff; postponing appointments for consultation, diagnostic and therapeutic purposes and rescheduling based on individualized risk stratification; telemedicine; preparation for possible issues on radiopharmaceuticals synthesis and delivery; preventing measures and protocols to minimize or avoid potential COVID-19 infection of patients and medical staff. This document should be considered as updated guidance on how clinical management of TNs and thyroid cancer has been altered, remodeled and adapted to the new circumstances in the COVID-19 era, based on the rapidly growing volume of scientific information regarding the new coronavirus.

Досліджено фотоелектричні характеристики структур ITO/CdTe, виготовлених методом термічного вакуумного випаровування та шляхом осадження у квазізамкненому об'ємі до та після різних обробок. Частина зразків проходила "хлоридну" обробку, інша – відпал на повітрі. Після цього проводилась обробка зразків у плазмі водню та нанесення на них тонкої алмазоподібної плівки. Показано, що проведення "хлоридної" обробки структур ІТО/CdTe приводить до збільшення дифузійної довжини носіїв заряду у шарі CdTe. Проведення термовідпалу не впливає на значення дифузійної довжини носіїв заряду у шарі CdTe, але значно підвищує фоточутливість, що свідчить про зменшення на поверхні шару CdTe швидкості поверхневої рекомбінації. Шляхом комбінації термовідпалу, "хлоридної" обробки, плазмової обробки у водні та нанесення тонких алмазоподібних плівок отримано збільшення довжини дифузії носіїв заряду у шарі CdTe в усіх досліджуваних структурах ІТО/CdTe. На структурах ІТО/CdTe, отриманих термічним вакуумним випаровуванням, обробка у плазмі водню приводила до значного збільшення спектральної чутливості у діапазоні довжин хвиль 400–800 нм, а на структурах, які пройшли "хлоридну" обробку, значне збільшення спектральної чутливості досягалось після обробки у плазмі водню нанесення алмазоподібних плівок.

In glacial archaeology, it has been employed successfully, but could see a wider application among practitioners. This article summarizes common remote sensing approaches useful to archaeologists in cryogenic environments. It covers simple applications using easily accessible data in order to enable the practitioner to monitor melt and contextualize archaeological sites within a larger landscape setting. The improved resolution and availability of remote sensing data enhances its usefulness with regards to identifying, documenting and monitoring sites in frozen environments and is a valuable addition to most field research pertaining to glacial archaeology.
Paleoecological and Archaeological Investigation of the ROMO 9 Ice Patch, Rocky Mountain National Park, Colorado, USA

Rocky Mountain National Park contains a dense record of prehistoric Native American archaeological locales and biological resources, but questions remain about the past use of the Park’s ice patches by ancient humans and animals. Our survey of 30 locations in the Park revealed that the majority of ice patches are small in size and contain limited evidence of past visitation by mobile peoples, but moderate use by game. In this paper, we present new radiocarbon dates for materials documented in the recently melted forefield of the ROMO 9 ice patch, a mid-sized ice body located in alpine tundra along the Continental Divide. Dated materials include timber-sized pine trees, keratin and bone collagen from large game (bighorn sheep, elk), and a possible wooden artifact made from Mountain mahogany. Results suggest most finds date to several periods of known neoglaciation, during the mid-Holocene (c. 4150 cal BP) and the Little Ice Age (c. 115 cal BP). Our results corroborate past findings on mid-Holocene timberline in the Colorado Front Range, as well as the paucity of archaeological evidence from small ice patches in Colorado.

Penelitian ini bertujuan untuk mengetahui urgensi konteks dalam analisis makna dan pandangan para ahli linguistik baik klasik maupun modern tentang teori kontekstual serta perannya dalam studi makna. Metode yang digunakan dalam penelitian ini metode deskriptif kualitatif. Hasil penelitian ini menyimpulkan bahwa konteks memiliki pengaruh sangat penting terhadap makna. Tanpa memerhatikan konteks maka mustahil menghasilkan makna yang benar. Pandangan mengenai konteks telah dipaparkan oleh banyak ilmuan bahasa sejak dulu, baik di timur maupun barat. Mereka diantaranya yaitu, Tamam Hasan, Akhmad Mukhtar Umar, Kamal Bashr, Malinowski, J.R. Firth, K. Amer dan H.D Hidayat. Semuanya sepakat bahwa konteks merupakan hal yang urgent dalam menyibak makna kata atau ujaran. Kata yang berada di luar konteks belum memenuhi syarat untuk memiliki makna.
