On the Closure of the Image of the Generalized Divisor Function
Authors: Sanna Carlo 
Published: February 2018

AbstractFor any real number s, let σsbe the generalized divisor function, i.e., the arithmetic function defined by σs(n) := ∑d|nds, for all positive integers n. We prove that for any r > 1 the topological closure of σ−r(N+) is the union of a finite number of pairwise disjoint closed intervals I1, . . . , Iℓ. Moreover, for k = 1, . . . , ℓ, we show that the set of positive integers n such that σ−r(n) ∈ Ikhas a positive rational asymptotic density dk. In fact, we provide a method to give exact closed form expressions for I1, . . . , Iℓand d1, . . . , dℓ, assuming to know r with sufficient precision. As an example, we show that for r = 2 it results ℓ = 3, I1= [1, π2/9], I2= [10/9, π2/8], I3= [5/4, π2/6], d1= 1/3, d2 = 1/6, and d3= 1/2.

Published: February 2018

Abstract
Single crystals of two novel uranyl sulfates and two novel uranyl selenates with protonated cyclen and 3-aminotropane molecules, ((C8H24N4)[(UO2)3(SO4)5](H2O)3 (I), (C8H24N4)(H5O2)(H3O)[(UO2)4(SeO4)7(H2O)](H2O)6.6 (II), (C8H18N2)(H5O2)(H3O)[(UO2)3(SO4)5(H2O)](H2O)0.5 (III), and (C8H18N2)(H5O2)(H3O)[(UO2)3(SeO4)5 (H2O)](H2O)2 (IV) have been prepared by isothermal evaporation from aqueous solutions and structurally characterized. Uranyl-containing 2D units have been investigated using topological approach and information-based complexity measures demonstrating that complex topologies form more rare than their simplest counterparts, which is a response of the crystal structure to changes of chemical conditions within the system.

Published: February 2018

Abstract
The investigation of the supramolecular interactions between the lithium isothiocyanate salt and 18-crown-6 (18C-6) in commercial tetrahydrofuran leads to the formation of a lithium compound, LiNCS(H2O)(18C-6) (1). In the crystal structure the asymmetric unit contains two similar LiNCS(H2O)(18C-6) molecules. Solid-state photoluminescence experiments have shown that compound 1 emits violet luminescence, and its possible emission mechanism was investigated in detail based on theoretical calculations.
Aminkomplexe des Goldes, Teil 10: Gold(I)-thiocyanat-Komplexe mit Tetrahydrothiophen, Dimethylsulfid, Ammoniak, Aminen und Azaaromatena

Published: February 2018

Abstract
The reaction of (tht)AuCl (tht=tetrahydrothiophene) with KSCN leads to a mixture of gold(I) thiocyanate AuSCN and [(tht)2Au]+ [Au(SCN)2]−
1. The compounds were separated and the X-ray structure of 1 confirmed as an alternating chain of anions and cations linked by aurophilic contacts. Either pure AuSCN or the mixture was used to synthesize further derivatives of AuSCN, all of which were investigated by X-ray methods. Most products were of limited stability when removed from their mother liquor. The dimethyl sulfide derivative 2 is molecular, (Me2S)AuSCN; the ammonia derivative 3 is ionic, [(NH3)2Au]+ [Au(SCN)2]−. The reaction with 2,2-bipyridyl leads (presumably by involvement of the solvent or of atmospheric moisture) to [bipy-H]+ [Au(SCN)2]−
13. All other products involve amines or azaaromatics as ligands L. The primary amine tert-butylamine forms an ionic product [L2Au]+ (SCN)−
4. The secondary amines piperidine and dibenzylamine lead to molecular structures LAuSCN (5 and 6), whereas pyridine-based azaaromatics lead to ionic products [L2Au]+ [Au(SCN)2]− with L=2-, 3- or 4-picoline (7–9), 2,4-, 3,4- or 3,5-lutidine (10–12). The 3,4-lutidine derivative 11 forms two polymorphs that tend to form mixed crystals. The dominant features of the crystal packing for 7–12 are short aurophilic interactions.

Abstract
Wen, N, Dalbo, VJ, Burgos, B, Pyne, DB, and Scanlan, AT. Power testing in basketball: Current practice and future recommendations. J Strength Cond Res 32(9): 2686–2700, 2018—Numerous foundational movements performed during basketball are predicated on underlying power-related attributes, including speed, change-of-direction (COD), and jumping. Accordingly, fitness testing batteries for basketball have incorporated an assortment of linear speed tests, COD tests, and jump tests. However, because of the wide variety of testing options, it is difficult for basketball practitioners to select appropriate testing protocols for the assessment of power-related attributes. As a result, there is a need to review the relevant literature to identify game-specific, power-related attributes important in basketball and the most appropriate tests available to assess power-related attributes for basketball practitioners. Therefore, the aims of this review were to: (a) identify essential power-related attributes important in basketball; (b) discuss the suitability of common and novel power-related tests; and (c) provide recommendations for future research and best practice approaches for basketball coaching staff. In this review, we propose a series of novel tests that are more targeted and specific to basketball movements including: (a) 5- and 10-m linear sprints, (b) modified agility T-test, (c) change-of-direction deficit (CODD), (d) lateral bound, (e) Sargent jump, (f) one-step jump, and (g) isometric midthigh pull test. Improved testing of power-related attributes should enable basketball practitioners to develop targeted training plans for enhancing player performance.

Abstract
McMahon, JJ, Suchomel, TJ, Lake, JP, and Comfort, P. Relationship between reactive strength index variants in rugby league players. J Strength Cond Res 35(1): 280–285, 2021—Two reactive strength index (RSI) variants exist, the RSI and RSI modified (RSImod), which are typically calculated during the drop jump (DJ) and countermovement jump (CMJ), respectively. Both RSI variants have been used to monitor athletes' ability to complete stretch-shortening cycle actions quickly, but they have never been compared. The purpose of this study was to determine whether they yield relatable information about reactive strength characteristics. Male professional rugby league players (n = 21, age = 20.8 ± 2.3 years, height = 1.82 ± 0.06 m and body mass = 94.3 ± 8.4 kg) performed 3 DJs (30 cm) and CMJs on a force plate. Reactive strength index and RSImod were subsequently calculated by dividing jump height (JH) by ground contact time (GCT) and time to take-off (TTT), respectively. All variables were highly reliable (intraclass correlation coefficient ≥0.78) with acceptable levels of variability (coefficient of variation ≤8.2%), albeit larger variability was noted for DJ variables. Moreover, there was a large relationship between RSI and RSImod (r = 0.524, p = 0.007), whereas very large relationships were noted between JHs (r = 0.762, p < 0.001) and between GCT and TTT (ρ = 0.705, p < 0.001). In addition, RSI (0.90 ± 0.22) was largely and significantly (d = 2.57, p < 0.001) greater than RSImod (0.47 ± 0.08). The DJ-derived RSI yields much larger values than the CMJ-derived RSImod and although a large relationship was noted between them, it equated to just 22% shared variance. These results suggest that the 2 RSI variants do not explain each other well, indicating that they do not assess entirely the same reactive strength qualities and should not be used interchangeably.

THIS ARTICLE PROVIDES A FRAMEWORK FOR SELECTING THE MOST APPROPRIATE ASYMMETRY EQUATION BASED ON THE SELECTED TEST METHOD, ENSURING ACCURATE CALCULATION AND INTERPRETATION. IN ADDITION, CONSIDERATIONS FOR DATA ANALYSIS HAVE ALSO BEEN INCLUDED AS A GUIDE FOR PRACTITIONERS ON THE RELEVANCE OF MONITORING INTERLIMB DIFFERENCES LONGITUDINALLY.
Extending Low-Temperature Differential Scanning Calorimetry from Paste to Mortar and Concrete to Quantify the Potential for Calcium Oxychloride Formation
Authors: Suraneni Prannoy , Weiss Jason 
Published: February 2018

Abstract
Calcium chloride–based deicing salts can react with calcium hydroxide in concrete pavements, resulting in the formation of calcium oxychloride. The formation of calcium oxychloride can cause damage in the pavements, especially at the joints. Recently, it has been shown that low-temperature differential scanning calorimetry can be used to measure calcium oxychloride contents in cement pastes exposed to calcium chloride. This article explores the extension of the low-temperature differential scanning calorimetry test method from applications on ground paste to ground mortar and concrete. Specifically, the influence of dilution due to the aggregate volume causes the measured amount of calcium oxychloride to be smaller in mortar and concrete than the pastes. To successfully measure the amount of calcium oxychloride, a higher powder-liquid ratio is used in concretes as compared to pastes. Low-temperature differential scanning calorimetry can successfully be used to measure the amount of calcium oxychloride in ground mortars and concrete; however, there is an increase in the variation of the measurement, and, as such, it is recommended that the average of three tests should be considered as a test specimen.

Published: February 2018

&nbsp;

The objective of this study was to develop
prediction functions for the variables that affect precision seeding
performance. The variables considered were the amount of vacuum, peripheral
speed and the diameter of the holes on vacuum plate. On the other hand, these
variables are significantly affected by physical properties of the seeds and
govern the seeding phenomenon that is the capture, release and incorporation of
seeds into the soil. Experiments using Central Composite Design which is one of
the designs in Response Surface Methodology (RSM) were conducted in the lab and
different seeds were used to meet the objective. Hence, using different seeds
with different physical and aerodynamic properties such as sphericity, thousand
seed mass, projected area, terminal velocity, mean particle diameter and
coefficient of friction of material on metal are expected to contribute the
development of prediction models for a maximized seeding performance.&nbsp; According to results of the statistical
analyses, hole diameter and vacuum pressure models were developed while no
significant model was developed for the peripheral the speed of the vacuum
plate. The appropriate hole diameter was found to be the function of mean
particle diameter and sphericity with a coefficient of determination of 92.69%,
while vacuum pressure was correlated to sphericity and terminal velocity (R2=76.74
%). The developed models were verified by the use of different seeds and seed
distribution was evaluated.

Aspectos da vida pública
Authors: Funari Pedro Paulo Abreu 
Published: February 2018

Este volume da Revista de Arqueologia Pública apresenta diversas contribuições no âmbito da vida em sociedade. A Arqueologia Pública amadureceu como parte das transformações da disciplina, desde a década de 1980, em particular, no sentido de aproximar-se das questões sociais e políticas. A criação do Congresso Mundial de Arqueologia, em 1986, foi decisiva não apenas ao romper com o caráter apolítico da ciência, como ao incluir na gestão do órgão – o World Archaeological Congress – os indígenas, as pessoas comuns e os acadêmicos de outras searas. Em pouco tempo, surgiram reflexões que sobre o caráter público da disciplina, em seus múltiplos aspectos, como consubstanciado na criação da revista Public Archaeology, em 2001, quadrimestral que logo se tornou a grande referência na área. Em menos de quinze anos, a publicação da The Oxford Handbook of Public Archaeology representou a consagração, em termos mundiais, da abordagem social e pública da disciplina.
A arqueologia na Unicamp e a Revista de Arqueologia Pública: Trajetória e perspectivas

Published: February 2018

Laboratório de Arqueologia Pública da Universidade Estadual de Campinas resulta de longa trajetória de engajamento da Universidade com a Arqueologia, em uma perspectiva científica fundada na excelência acadêmica, na inserção internacional e no engajamento social. A Unicamp surgiu em meio a um regime de força, inspirado no MIT e voltada para os saberes técnicos que pudessem transcender os questionamentos políticos que advinham das universidades de referência à época e cujos quadros foram golpeados de forma mais dura: a Universidade de São Paulo e a Universidade Federal do Rio de Janeiro. A Universidade Estadual de Campinas, fundada em 1966, no entanto, logo teve no desafio de produzir ciência de relevância internacional não um obstáculo, mas um meio de contrapor-se às exações políticas que grassavam alhures na academia, ao acolher cientistas notáveis perseguidos tanto no Brasil, como em outros países latino -americanos sob o jugo ditatorial.
Teoria e epistemologia do conhecimento arqueológico
Authors: Funari Pedro Paulo Abreu 
Published: February 2018

A Arqueologia, desde o início, esteve na dependência de uma questão epistemológica de fundo: como se pode conhecer algo por meio de meros vestígios materiais? Nos séculos do Antiquariado, desde o Renascimento, antes mesmo da moderna Arqueologia, as estátuas antigas só revelavam os seus segredos por meio de análises comparativas e estilísticas. Não havia conhecimento imediato, nem a mera percepção das pessoas bastava para que se pudessem formular interpretações sobre os objetos artísticos dos antigos. A partir do século XVIII, foi a Filologia, com seus pressupostos filogenéticos e genealógicos a fornecer os parâmetros para entender um universo material crescente e cada vez mais diversificado como uma linguagem a ser decifrada. Em certo sentido, essa abordagem fundada na linguística está na disciplina até hoje, ainda que sob alguns influxos novos, derivados de Saussure ou de Chomsky, temperados pela hermenêutica, essa também baseada no estudo taxonômico.

Authors: Ortega-Altamirano Doris Verónica , Rodríguez-Oliveros Guadalupe , González-Unzaga Marco Aurelio , Reyes-Morales Hortensia 
Published: February 2018

Objective. To identify strengths, weaknesses, opportunities, and threats (SWOT) perceived by childcare staff for preventing childhood overweight. Materials and methods. Qualitative study using an interpretative phenomenological approach; 18 in-depth, semi-structured interviews and 12 focus groups with 89 key informants working in six Mexican public childcare centers (CCC) were conducted. Through Content and SWOT analyses, experts further ranked fiftynine recurrent perceptions regarding healthy feeding and physical activity (PA), using the Delphi method. Results. Strengths: Acknowledgement of the CCC’s responsibility in fostering healthy feeding, availability of organizational regulations, and access to PA infrastructure/indoor activities. Weaknesses: Disregard of preschool overweight as a health problem, nutritional misperceptions, and perceived risk of child injuries while conducting PA. Opportunities: Willingness to reduce children’s access to junk foods, and parental active play with children during weekends. Threats: Limited family nutritional education, and restricted parental time/economic constraints/access to safe public spaces for PA. Conclusion. The identified SWOT must be considered when developing obesity-prevention interventions targeted at CCC.
