Published: September 2020

Every individual or agency activity will generate greenhouse gas emissions which could be countable and expressed as equivalent to carbon dioxide. One of the activities that produce carbon emissions is activities carried out on the campus, one of which is Batanghari University. Batanghari University consists of 5 faculties, namely the Faculty of Teacher Training and Science, Faculty of Law, Faculty of Economics, Faculty of Engineering and Faculty of Agriculture with a total population of Batanghari University of 5,582 people including 5,278 students, 210 lecturers and 94 education staff. This study aims to analyze the amount of carbon emissions generated from activities of the Batanghari University and to compare the percentage of total carbon emissions produced from each scope. Calculation of carbon emissions using the method of The Greenhouse Gas Protocol (GHG Protocol), by dividing it into 3 scopes, including calculating the carbon footprint from transportation activities, emission form the used of gas, and emissions from electricity used and the used of paper. Carbon dioxide (CO2) emissions calculated by using the IPCC (International Panel On Climate Change) method. The results showed that the total carbon footprint produced at the Batanghari University for 6 months was 790.24 ton.CO2-eq. The distribution of emissions based on the scope as follows : scope 1 activity of electricity consumption was 162,705 ton.CO2-eq; scope 2 activities of using LPG was 0.609 ton.CO2-eq; and the scope 3 transportation activities of lecturers, students and education staff was 625.91 ton.CO2 -eq and paper usage activity are 1.0247 ton.CO2-eq. The largest carbon footprint was generated from transportation activities at 79.2% and the smallest was the use of LPG at 0.07%.
Evaluating the Heterogeneous Effect of Firm Risk on Firm Value
Authors: Nhung Nguyen Thi Hong 
Published: September 2020

Purpose- This paper aims to investigate the effect of firm risk on the firm value to see how the firm value is changing when the risk level is changed. Our result indicates that a higher level of risk can reduce firm value. Design/Methodology- We apply a Bayesian causal technique for a sample data set of US public firms. The causal approach helps us to focus on the reliable and unbiased results instead of the association-based findings. Findings- The results show a negative effect of risk on the firms’ value for the sample data. However, we investigate the potential effect of the risk across the distribution of the firm value. We witness the more substantial effect of risk on firms with a higher value. Practical Implications- Helps firms to evaluate their risk and its effect, so they can adjust their decisions and take actions to reduce the undesired effects of firm risk.

Estas cepas produjeron tres y dos compuestos, respectivamente, que mediante comparación de las señales identificadas en el espectro de 1HNMR, con las reportadas en la literatura, podemos suponer que corresponden a pigmentos de tipo xantona y antraquinona de color rojo-vino.
Determination of the residential renovation range
Authors: Bucoń Robert , Sobotka Anna 
Published: September 2020

The article addresses the problem of selecting renovation solution which is a difficult task. It requires the administrator to consider and compare benefits that result from the execution of particular repairs. The priority is to define both the urgency of repair and the financial constraints. Thus, the choice of renovation solution fulfilling these conditions requires a systematic approach. The proposed method allows the decision-maker to assess the state of building, on which basis it is possible to indicate a needed range of renovation – including the information about the level of urgent repairs. During the next stage of calculations, the significance of the selection criteria is defined by means of the fuzzy AHP method. The assessment of these criteria provides the basis for prioritizing and choosing the renovation solutions and is proposed to be conducted by means of TOPSIS method. To illustrate the method, the authors present a numerical example of the proposed approach to selecting renovation solution method applied to a residential building.
Preliminary identification and evaluation of parameters affecting the capacity of the operator-earthmoving machine system
Authors: Radziszewska-Zielina Elżbieta , Sobotka Anna , Plebankiewicz Edyta , Zima Krzysztof 
Published: September 2020

Without reliable data on the time of work of construction machines it is impossible to calculate the cost of the investment or the time limit for its implementation. Machine capacity is affected by many factors resulting from both the technical capabilities of a machine (e.g. the engine and bucket capacity) and work environment (e.g. soil loosening and weather conditions). Capacity is also influenced by factors affecting the operator (e.g. health condition, stress, fatigue). Therefore, it is appropriate to use the concept of the operator-machine system.
The current system for the standards of machine working time collected in catalogues of capital expenditures is outdated (a lack of modern materials, technology and equipment currently used). It does not take into account all possible weather conditions, labour conditions and soil and water conditions. The result of this state of affairs may be overestimation or underestimation of an investment.
On the basis of the conducted research it may be concluded that the greatest impact on the capacity of the operator-earthmoving machine system is exerted by parameters associated with the psychophysical condition of the operator (experience, fatigue, health and motivation of the operator) and the technical parameters of the machine (technical condition and theoretical technical capacity). Weather conditions, particularly air humidity, affect the performance to the smallest extent.
Influence of concrete topping on behaviour of prestressed Hollow Core floor slabs on flexible supports
Authors: Derkowski Wit , Surma Mateusz 
Published: September 2020

Slim Floors (SF) are the structures made of the Hollow Core (HC) slabs supported on the slender beams, where the beam height is usually slightly greater than the height of precast slab element. With the increase of the supports' deflection, the deformation of the HC slab occurs, and in consequence, additional transverse normal and shear stresses appear in the precast element, which can cause a diagonal cracking and destruction of external webs of this element. It may also result in longitudinal cracks on bottom surface of the slab. Despite the frequent implementation of this type of structures, the existing standard EN 1168 gave only a brief record of the need to take the reduction in design shear capacity into account, but is not given any calculation procedure.
It is widely believed that reduction of unfavourable effects of shear stress in the HC slab’s web can be achieved by filling the cores with concrete or arrangement of the monolithic layer or concrete topping. The fib guidelines are practically the only one document which allows to determine the shear capacity of SF slabs, including the influence of concrete topping or core filling – brief description of this design model is presented in the paper. In order to determine the effect of concrete topping on the behaviour of prestressed HC slabs on the flexible supports, a number of calculation analyzes were performed, which take into account the effects of thickness of the concrete topping, the value of the friction coefficient between the concrete topping and the precast element, the sequence of concreting of vertical joints and topping layer and the amount of supplementary reinforcement in the topping. The results of the calculations, and the conclusions derived from them, are presented in the article.

Authors: Helmita Helmita , Putri Elsa Mayora 
Published: September 2020

The problem in this thesis is Devotion and commitment in a contradictory conditions in the relationship between Noah and Allie who have differences in social status. Until their relationship was opposed by Allie's mother, even so Allie remained devotion to choose Noahh. Devotion and commitment to the contradictory conditions between Noah and Allie also occur when they are old. Noah remained loyal to Allie when she suffered from Alzheimer's disease.
The object of this study was The Notebook novel by Nicholas Sparks. This research uses Sigmund Freud's theory of personality psychology. The results of this study are the figures Noah and Alli have personality aspects that refer to Sigmund Freud's theory of id, ego, superego. The writer uses descriptive analysis method and qualitative method. The author carries out a systematic procedure with an understanding of the novel, figures Noah and Allie, and also structural theory.
This research aims : (1) to analyze the importance of loyalty and commitment in contradictory conditions. (2) to describe the loyalty and commitment contained in the Novel The notebook. (3) to explain the loyalty and commitment shown by Noah and Allie after marriage.
Based on the results of this analysis it can be concluded that the problem faced by the main character is his deep love and loyalty to his wife, Noah did everything for Allie, including writing to him for two years even though his letter was never responded by Allie. But when they met for the first time after being separated for quite a long time their love for each other was still there. Until they married and aged together and Allie contracted Alzheimer's disease, but Noah remained faithful with her.
Covers, Orientations and Factors
Authors: Csikvári Péter , Imolay András 
Published: September 2020

Given a graph $G$ with only even degrees, let $\varepsilon(G)$ denote the number of Eulerian orientations, and let $h(G)$ denote the number of half graphs, that is, subgraphs $F$ such that $d_F(v)=d_G(v)/2$ for each vertex $v$. Recently, Borbényi and Csikvári proved that $\varepsilon(G)\geq h(G)$ holds true for all Eulerian graphs, with equality if and only if $G$ is bipartite. In this paper we give a simple new proof of this fact, and we give identities and inequalities for the number of Eulerian orientations and half graphs of a $2$-cover of a graph $G$.
A Combinatorial Model for the Decomposition of Multivariate Polynomial Rings as $S_n$-Modules
Authors: Orellana Rosa , Zabrocki Michael 
Published: September 2020

We consider the symmetric group $S_n$-module of the polynomial ring with $m$ sets of $n$ commuting variables and $m'$ sets of $n$ anti-commuting variables and show that the multiplicity of an irreducible indexed by the partition $\lambda$ (a partition of $n$) is the number of multiset tableaux of shape $\lambda$ satisfying certain column and row strict conditions. We also present a finite generating set for the ring of $S_n$ invariant polynomials of this ring.
$4$-Colouring of Generalized Signed Planar Graphs
Authors: Jiang Yiting , Zhu Xuding 
Published: September 2020

Assume $G$ is a graph and $S$ is a set of permutations of positive integers. An $S$-signature of $G$ is a pair $(D, \sigma)$, where $D$ is an orientation of $G$ and $\sigma: E(D) \to S$ is a mapping which assigns to each arc $e=(u,v)$ a permutation $\sigma(e)$ in $S$. We say $G$ is $S$-$k$-colourable if for any $S$-signature $(D, \sigma)$ of $G$, there is a mapping $f: V(G) \to [k]$ such that for each arc $e=(u,v)$ of $G$, $\sigma(e)(f(u)) \ne f(v)$. The concept of $S$-$k$-colourable is a common generalization of many colouring concepts. This paper studies the problem as to which subsets $S$ of $S_4$, every planar graph is $S$-$4$-colourable. We call such a subset $S$ of $S_4$ a good subset. The Four Colour Theorem is equivalent to saying that $S=\{id\}$ is good. It was proved by Jin, Wong and Zhu (arXiv:1811.08584) that a subset $S$ containing $id$ is good if and only if $S=\{id\}$. In this paper, we prove that, up to conjugation, every good subset of $S_4$ not containing $id$ is a subset of $\{(12),(34),(12)(34)\}$.
Another Approach to Non-Repetitive Colorings of Graphs of Bounded Degree
Authors: Rosenfeld Matthieu 
Published: September 2020

We propose a new proof technique that applies to the same problems as the Lovász Local Lemma or the entropy-compression method. We present this approach in the context of non-repetitive colorings and we use it to improve upper-bounds relating different non-repetitive chromatic numbers to the maximal degree of a graph. It seems that there should be other interesting applications of the presented approach.
In terms of upper-bounds our approach seems to be as strong as entropy-compression, but the proofs are more elementary and shorter. The applications we provide in this paper are upper bounds for graphs of maximal degree at most $\Delta$: a minor improvement on the upper-bound of the non-repetitive chromatic number, a $4.25\Delta +o(\Delta)$ upper-bound on the weak total non-repetitive chromatic number, and a $ \Delta^2+\frac{3}{2^{1/3}}\Delta^{5/3}+ o(\Delta^{5/3})$ upper-bound on the total non-repetitive chromatic number of graphs. This last result implies the same upper-bound for the non-repetitive chromatic index of graphs, which improves the best known bound.
Influences of luminance contrast and ambient lighting on visual context learning and retrieval
Authors: Zang Xuelian , Huang Lingyun , Zhu Xiuna , Müller Hermann J. , Shi Zhuanghua 
Published: September 2020

AbstractInvariant spatial context can guide attention and facilitate visual search, an effect referred to as “contextual cueing.” Most previous studies on contextual cueing were conducted under conditions of photopic vision and high search item to background luminance contrast, leaving open the question whether the learning and/or retrieval of context cues depends on luminance contrast and ambient lighting. Given this, we conducted three experiments (each contains two subexperiments) to compare contextual cueing under different combinations of luminance contrast (high/low) and ambient lighting (photopic/mesopic). With high-contrast displays, we found robust contextual cueing in both photopic and mesopic environments, but the acquired contextual cueing could not be transferred when the display contrast changed from high to low in the photopic environment. By contrast, with low-contrast displays, contextual facilitation manifested only in mesopic vision, and the acquired cues remained effective following a switch to high-contrast displays. This pattern suggests that, with low display contrast, contextual cueing benefited from a more global search mode, aided by the activation of the peripheral rod system in mesopic vision, but was impeded by a more local, fovea-centered search mode in photopic vision.

Published: September 2020

Objective: Current analysis aims at in-vivo investigation of analgesic and anti-inflammatory activities of Aitchisonia rosea methanolic extract.
Methods: Albino mice (20-30 g) were used in the study. Extract at 200, 400 and 800 mg/kg doses was tested against egg albumin and carrageenan induced mice paw edema along with formalin persuaded paw licking and acetic acid prompted writhing for analgesic activity.
Results: Results depicted dose reliant and significant (p<0.001) inhibition of carrageenan as well as egg albumin brought paw edema, abdominal constrictions/ hind limb stretching tempted by acetic acid and formalin instigated paw licking. Capability of crude extract to halt inflammatory and analgesic response was akin to that of ibuprofen in all models.
Conclusion: The current findings support the use of Aitchisonia rosea for inflammatory conditions, which might be attributed to its previously proven high alkaloid, flavonoids, phenol, tannins content and free radical scavenging activity.
The Sizes of z ∼ 9−10 Galaxies Identified in the Brightest of Reionizing Galaxies (BoRG) Survey

Abstract
Redshift z = 9–10 object selection is the effective limit of Hubble Space Telescope (HST) imaging capability, even when confirmed with Spitzer. If only a few photometry data points are available, it becomes attractive to add criteria based on their morphology in these J- and H-band images. One could do so through visual inspection, a size criterion, or alternate morphometrics. We explore a vetted sample of Brightest of Reionizing Galaxies (BoRG) z ∼ 9 and z ∼ 10 candidate galaxies and the object rejected by Morishita+ to explore the utility of a size criterion in z = 9–10 candidate selection. A stringent, point-spread function (PSF)-corrected effective radius criterion (

) would result in the rejection of 65%–70% of the interlopers visually rejected by Morishita et al. It may also remove up to ∼20% of bona fide brightest (

) z = 9 or 10 candidates from a BoRG selected sample based on the Mason et al. luminosity functions, assuming the Holwerda et al.

size–luminosity relation. We argue that including a size constraint in lieu of a visual inspection may serve in wide-field searches for these objects in, e.g., Euclid or HST archival imaging with the understanding that some brightest (

) candidates may be missed. The sizes of the candidates found by Morishita et al. follow the expected size distribution of z ∼ 9 for bright galaxies, consistent with the log normal in Shibuya et al. and single objects. Two candidates show high star formation surface density (

) and all merit further investigation and follow-up observations.
