Abstract
The sorption kinetics and equilibrium isotherms of zirconium, uranium, and molybdenum ions onto synthetic polyaniline/SiO2 composite (PAn/SiO2) have been studied using batch-sorption techniques. This study was carried out to examine the sorption behavior of the PAn/SiO2 for the removal of Zr(IV), U(VI), and Mo(VI) ions from an aqueous solution. The influence of some parameters on the sorption process was also studied. The maximum sorption for Zr(IV), U(VI), and Mo(VI) ions was achieved at 60 min shaking time. Langmuir isotherm model is the most representative for discussing the sorption process with a maximum sorption capacity of 24.26, 21.82, and 13.01 mg/g for Zr(IV), U(VI), and Mo(VI) ions, respectively. Kinetic modeling revealed that the sorption of all ions follows the pseudo-second-order kinetic model. The results demonstrated that both the external and intra-particular diffusion are taken into account in determining the sorption rate. Thermodynamic parameters like ΔG°, ΔH°, and ΔS° for the sorption process were evaluated. The synthetic composite has been successfully applied for the removal and recovery of U(VI) ions from real solution (monazite leachate) using a chromatographic column packed with PAn/SiO2 composite with a breakthrough capacity equal to 239.70 mg/g.
A Stylistic Analysis of Selected Christian Religion Print Advertisement in Ibadan Metropolis, Oyo State

Published: January 2021

Abstract
Print advertisements, a denominator of social realities have been approached from varied linguistic orientations. Studies that have dealt with how religious groups and churches utilize print advertisement to elicit patronage are discovered as inadequate. Anchored on the principles of linguistic stylistics, this study therefore investigates some religious advertisements with a view to determining how meaning is stylistically indexed in religious discourse at the graphological level. Qualitative research method with the analysis of corpus of selected texts was adopted at the graphological level of stylistics. Data for the study consisted of a total of thirteen (13) religious advertisements which are purposively sampled from selected church handbills, posters and flyers. The language of religious advertisement indicates how people’s linguistic choices are influenced by their religious persuasions and beliefs. The advertisers employ diverse linguistic features such as pictorial elements, graphological devices of italicization, icons, capitalization, punctuation marks and figures. The choice of the words is very simple, and there are elements of code – mixing. Also, a lot of images common to the Christendom are used such as the sign of the cross and the pictures of dove, clock and cup of wine, as an indication that the adverts are meant for Christians. The study provokes a deep understanding of how language gives expression to religious discourse. The advertisers’ understanding of the people of the religious inclination inform their choice of language and semiotic features.

Published: January 2021

Abstract

Objectives
Chronic, clinical pain states are often accompanied by distress such as anxiety and depression. The aim of this study was to determine if certain clinical pain variables could predict the level of anxiety and depression in subjects with musculoskeletal pain.

Methods
Two multiple linear regression analyses were conducted on a sample consisting of 189 subjects with clinical pain with the independent pain variables of pain intensity, the influence of pain on daily activities, pain persistence, pain duration, and the number of pain locations. The dependent variables measured anxiety and depression, respectively.

Result
Two statistically significant models were found, where the predicted variables accounted for 37.0% of the variability in the anxiety levels and 43.7% of the variability in the depression levels. The independent variable, the influence of pain on daily activities, significantly predicted the level of anxiety. The variables, the influence of pain on daily activities and the number of pain locations, significantly predicted the levels of anxiety and depression.

Conclusions
This study showed that two different independent variables, the influence of pain on daily activities and the number of pain locations, significantly predicted the levels of depression. The predictor, the influence of pain on daily activities, significantly predicted the levels of anxiety. The knowledge gained about which specific pain variables are more likely to coexist with anxiety and depression in clinical pain states could be important in implementing holistic treatment plans for chronic pain.

Choice behavior is characterized by temporal discounting, i.e., preference for immediate rewards given a choice between immediate and delayed rewards. Agouti-related peptide (AgRP)-expressing neurons located in the arcuate nucleus of the hypothalamus (ARC) regulate food intake and energy homeostasis, yet whether AgRP neurons influence choice behavior and temporal discounting is unknown. Here, we demonstrate that motivational state potently modulates temporal discounting. Hungry mice (both male and female) strongly preferred immediate food rewards, yet sated mice were largely indifferent to reward delay. More importantly, selective optogenetic activation of AgRP-expressing neurons or their axon terminals within the posterior bed nucleus of stria terminalis (BNST) produced temporal discounting in sated mice. Furthermore, activation of neuropeptide Y (NPY) type 1 receptors (Y1Rs) within the BNST is sufficient to produce temporal discounting. These results demonstrate a profound influence of hypothalamic signaling on temporal discounting for food rewards and reveal a novel circuit that determine choice behavior.SIGNIFICANCE STATEMENTTemporal discounting is a universal phenomenon found in many species, yet the underlying neurocircuit mechanisms are still poorly understood. Our results revealed a novel neural pathway from agouti-related peptide (AgRP) neurons in the hypothalamus to the bed nucleus of stria terminalis (BNST) that regulates temporal discounting in decision-making.
La liberación del reconocimiento

La Teoría Crítica contemporánea presenta un curioso movimiento. Mientras que, por un lado, solicita las categorías de Marx para dar cuenta del fenómeno reciente de la crisis del capitalismo neoliberal; al mismo tiempo, reconoce que esa teoría no puede decirlo todo, requiriendo de un acercamiento de su perspectiva hacia objetos y problemas ajenos, acaso obstruidos por los límites al interior de los cuales se habría desplazado su pensamiento. Una de las fuentes de inspiración más poderosas de este movimiento de ampliación cuyo saldo no es sino una verdadera heteroglosia filosófica, se encuentra en la teoría del espíritu del idealismo alemán, más precisamente en sus modulaciones hegelianas. El regreso a Hegel vendría motivado por la necesidad de indagar, como se observa en la obra de Axel Honneth, en los dilemas de los vínculos humanos en un mundo social signado por el fenómeno de la fragmentación. En este escrito nos detendremos en analizar algunos elementos de un reciente debate al interior de la Teoría Crítica contemporánea acerca del problema de la articulación entre reconocimiento y libertad, reconstruyendo las distintas estrategias de lectura de Hegel que aquí se ponen en movimiento.
The Home of the Beves Saga
Authors: Hoyt Prentiss C. 
Published: January 2021

The question of the original home of the Beves saga has often been discussed, but no satisfactory conclusion has been reached. The conjectures regarding it have been various, but as yet unconvincing.Amaury Duval 1 places the scene of the story in France at Antonne, but without giving definite grounds for this supposition. Turnbull 2 and Kölbing3 both adopt this view without argument. Pio Rajna4 was the first to suggest a Germanic home for the saga, locating Hanstone (Hamtoun) on the continent near the French border of Germany. The arguments given are unimportant, but this view of the origin has been accepted by Gaston Paris,5 although he takes exception to Rajna's wildest suppositions as to the name Hanstone. Albert Stimming6 has exposed the weakness of Rajna's reasoning, but even he leaves the question still unsettled. Later in his introduction, he gives impartially the arguments in favor of French as well as those in favor of Germanic origin, but does not regard them as sufficient ground for forming an opinion. These comprise the conjectures thus far advanced, and all are weakly supported and inconclusive.
Mrs. Mary Davys: Forerunner of Fielding
Authors: McBurney William H. 
Published: January 2021

After the scores of “secret histories,” “authentick memoirs,” and “true relations” written by Mrs. Eliza Haywood and other female novelists of the 1720's, the four volumes of fiction by Mrs. Mary Davys produce much the same “cheerful, sunshiny, breezy” effect that Coleridge attributed to Fielding's work, in contrast to “the close, hot, day-dreamy continuity of Richardson.” The double comparison is more than subjectively valid, for Mrs. Davys stands in much the same relation to Fielding's ebullient masculine genius that Mrs. Haywood's distressed damsels do to Richardson's heroines—both as a forerunner and as an influence upon the early eighteenth-century reading public.Many of the qualities which distinguish Mrs. Davys from her contemporaries may be explained by her background and by the circumstances under which her works were written and published. She was born in Dublin in 1674 and married the Reverend Peter Davys, a friend of Jonathan Swift and headmaster of the free school attached to St. Patrick's. Swift considered the marriage an indiscretion on the headmaster's part but, indiscreet or not, it was apparently a happy one until Davys'early death in 1698. Soon after this, his young widow “went for mere want to England.” She appeared briefly in London in 1700 and then settled in York where she lived for the next fifteen years. Little is known of her during this period. Swift's correspondence and his Journal to Stella indicate that she occasionally visited London, that she tried by various ruses to maintain contact with him from York, and that he grudgingly sent her several sums of money before his return to Ireland in 1714. Such irregular charity could hardly have been sufficient for the most frugal existence, and from pictures of life in a York boarding house and the recurrent character of a settled but good-natured female companion in her plays and novels, one may conjecture that Mrs. Davys enacted a similar role in private life.

Authors: Rajaseharan Divya , Shanu J. E. Jeffin , Thulasiraman Shrinithi 
Published: January 2021

Background: Consumption of caffeine in adequate quantities has no adverse effects, but prolonged consumption makes it addictive. Medical students especially Interns due to their long working hours often indulge in excessive caffeine consumption. Objectives were to assess the knowledge of caffeine addiction among the medical interns, to assess the pattern of caffeine dependence among them and to calculate the caffeine dependence among them. Methods: It is a cross sectional descriptive study conducted among 124 medical interns of Trichy SRM Medical College Hospital and Research Centre using a pre-tested, self-administered questionnaire.Results: High level of knowledge was found in 47 (37.90%) participants, moderate level in 34 (27.41%) participants and low level of knowledge was found in 47 (34.67%) participants. The most preferred beverage was coffee 70 (56.45%) persons and second was tea 32 (25.80%). Majority of the study population 110 (88.7%) started consuming caffeinated products only after 5 years of age. Head ache 51 (41.12%) and exam durations 50 (40.32%) were common occasions of high caffeine intake. Among the study population, major group had either no 99 (79.83%) or just thirst 10 (8.06%) as withdrawal symptoms. Only 19.35% of them had caffeine dependence. Conclusions: Though the dependence level is low, the magnitude of the problem is big and self-awareness of this dreadful habit is necessary. Thus, prompt recognition of symptoms of dependence, tolerance and intoxication is necessary to avoid them falling a prey to this habit in the future.
Channel Profile Response to Abrupt Increases in Mountain Uplift Rates: Implications for Late Miocene to Pliocene Acceleration of Intracontinental Extension in the Northern Qinling Range-Weihe Graben, Central China
Authors: Wang Yizhou , Zheng Dewen , Zhang Huiping , Yu Jingxing , Pang Jianzhang , Hao Yuqi 
Published: January 2021

Abstract
Cenozoic extension of the Qinling range-Weihe Graben system has occurred in response to the uplift and growth of the Tibetan Plateau. Rapid exhumation of the northern Qinling range since the late Miocene is also regarded as resulting from the eastward expansion of the northeast part of Tibet. Tectonic evidence of this in the landscape remains unclear, but the fluvial system can provide a sensitive proxy record of tectonic forcing through space and over time scales of 105–107 a. Here, we present a study of channel profiles in the northern Qinling range, which forms a footwall highland separated from the southern Weihe Graben by active normal faults. We identify a population of knickpoints that separate river profiles with a gentle upstream gradient from steeper downstream reaches. Above the knickpoints, steepness indices increase from the central part towards the west and east, whereas channel steepness shows its highest values in the Huaxian-Huayin section. We observed no systematic changes of channel steepness pattern as a function of rock resistance, drainage area, or channel concavity. Correlation analysis between channel steepness and basin elevation and relief documents the control of tectonic forcing on regional topography. While bearing no relation to geological outcrop boundaries, the knickpoints show a strong correlation between retreat distance, catchment area, and river length. We infer that the knickpoints formed in response to an increase in mountain uplift rates and retreated as a kinematic wave. Under linear slope exponent n, we calibrated channel erodibility K~1.00±0.44×10−6 m0.1/a and derived knickpoint ages of 5.59±1.80 Ma. Combining the ages of onset of active faulting and mountain growth in the NE Tibetan Plateau (8–10 Ma, e.g., Liupan Shan, Jishi Shan, and eastern segments of the Haiyuan and Kunlun faults) and in the southwest Qinling range (9–4 Ma), we conclude that growth of the NE Tibetan Plateau began in the mid-Miocene time and expanded eastwards to the Qinling range-Weihe Graben during the late Miocene and early Pliocene.
Mechanism and Effect of Nanoparticles on Controlling Fines Migration in Unconsolidated Sandstone Formations

Published: January 2021

Summary
Pore throat blockage due to fines migration during drilling and completion is one of the leading causes of damage to unconsolidated sandstone reservoirs. Therefore, it is necessary to explore an effective control method for fines migration. Five types of nanoparticles in suspension with aqueous NaCl solutions of six different ionic strengths were chosen. Their ability to control the migration of quartz and kaolinite fines in quartz sand as the porous medium is discussed in this work. Results show that nanoparticles can effectively adsorb and fix fines, thus successfully suppressing their migration. Among these nanoparticles, Al2O3 showed the best performance, and nanoparticle suspensions with higher ionic strengths were preferable. A surface element integration method was used to establish a mathematical model for calculating the interaction energy between the formation fines and the rock pore surface with adsorbed nanoparticles. Through atomic force microscopy and zeta potential measurements, the effect of nanoparticle adsorption on the heterogeneity of the pore surface was analyzed in terms of roughness and electrical properties. The interaction energy between the formation fines and the heterogeneous pore surface was calculated; it revealed the microscopic mechanism of how nanoparticles control fines migration. The results indicated that the nanoparticles form an adsorption layer, which enhances the physical and chemical heterogeneities of the pore surface and provides favorable conditions for the adsorption and fixation of fines. As a result, the interaction energy curves of the fines and the pore surface shift downward, and their repulsive barriers decrease or even disappear, exhibiting higher attractive potential energy. These variations promote adsorption and fixation of fines at the pore surface, as confirmed by the experimental results reported in this work, thus successfully preventing formation damage.
New language versions of MAIN: Multilingual Assessment Instrument for Narratives – Revised
Authors: Gagarina Natalia , Lindgren Josefin 
Published: January 2021

The Multilingual Assessment Instrument for Narratives (MAIN) is a theoretically grounded toolkit that employs parallelpictorial stimuli to explore and assess narrative skills in children in many different languages. It is part of the LITMUS (Language Impairment Testing in Multilingual Settings) battery of tests that were developed in connection with the COST Action IS0804 Language Impairment in a Multilingual Society: Linguistic Patterns and the Road to Assessment(2009−2013). MAIN hasbeen designed to assess both narrative production and comprehensionin children who acquire one or more languages from birth or from early age. Its design allows for the comparable assessment of narrative skills in several languages in the same child and in different elicitation modes: Telling, Retelling and Model Story. MAIN contains four parallel stories, each with a carefully designed six-picture sequence based on a theoretical model of multidimensional story organization. The stories are controlled for cognitive and linguistic complexity, parallelism in macrostructure and microstructure, as well as for cultural appropriateness and robustness. As a tool MAIN had been used to compare children’s narrative skills across languages, and also to help differentiate between childrenwith and without developmental language disorders, both monolinguals and bilinguals.
This volume consists of two parts. The main content of Part I consists of33 papers describing the process of adapting and translating MAIN to a large number of languagesfrom different parts of the world. Part II contains materials for use for about 80 languages, including pictorial stimuli, which are accessible after registration.
MAIN was first published in 2012/2013 (ZASPiL56). Several years of theory development and material construction preceded this launch. In 2019 (ZASPiL 63), the revised English version (revised on the basis of over 2,500 transcribed MAIN narratives as well as ca 24,000 responses to MAIN comprehension questions, collected from around 700 monolingual and bilingual children in Germany, Russia and Sweden between 2013-2019) was published together with revised versions in German, Russian, Swedish, and Turkish for the bilingual Turkish-Swedish population in Sweden. The present 2020 (ZASPiL 64) volume contains new and revised language versions of MAIN.

[Design of air conditioning system based on the energy and costs aspect of hotel buildings in Semarang] Indonesia’s economic growth has been above 5% for the past few years. Tourism industry is one of the sectors that shows a significant progress. The improvement in tourism industry has to be supported with good hospitality industry as well. Air conditioning system is one of the main utilities in a hotel building. The design of the air conditioning system for a hotel building must pay close attention to the thermal comfort factor for the guests, safety factor, and energy and cost efficiency aspect of it. Air conditioning system design consists of cooling load calculation for the hotel, air conditioning system selection, energy and cost calculation using the life cycle cost analysis. The maximum cooling load in this hotel is 3.279 kW. From that cooling load, three alternative systems are being considered, which are the central air conditioning system using chiller machine that has constant flowrate, the central air conditioning system using chiller machine that has variable flowrate, and the split air conditioning system using VRF machine. Energy analysis and life cycle cost analysis for 20 years was performed to be able to decide the best system. From that energy and cost analysis it can be concluded that the second alternative, which is three units of chiller with variable discharge with a capacity of 1,100 kW for each chiller, is the best system for the hotel. This system has an energy consumption intensity value of 118 kWh/m2 per year and total cost of Rp. 87,707,416,390 for a period of 20 years.
Emerging Role of Terpenoids for the Treatment of Cancer: A Review
Authors: Chopra Bhawna , Dhingra Ashwani Kumar , Dhar Kanaya Lal , Nepali Kunal 
Published: January 2021

Aim:
Terpenes are natural compounds found in several organisms belonging to the animal
and plant kingdom, therefore, constitute the largest class of natural products and were a rich reservoir
of candidate compounds for drug discovery. The review aims to focus on the extensive potential of the
anti-cancer terpenoid components obtained from natural plant species which may lead to the development
of a variety of derived terpenoids moieties.

Method:
Literature survey has been carried out to determine the overwelhming potential
of terpenoids.

Results:
The present article provides an overview of the development of the isoprene unit and the generation
of the various types of terpenes that exhibits pharmacological potential. The anti-cancer activity
of terpenoids appears promising and will potentially open more opportunities for cancer therapy.
However, current studies are restricted to descriptive findings and some of them lack mechanistic insights
and systematic structure--activity relationship studies. Future efforts into the systematic identification
of the targets of terpenoids are believed to increase the chances of gaining breakthrough insights
in the field.

Conclusion:
There is still hope that new therapeutic options for the control of cancer and any other
painful syndromes will be developed from terpenes, which were proved to be great candidates for
cancer therapeutics.
