Comparison of Composite and Star-forming Early-type Galaxies

I assemble 4684 star-forming early-type galaxies (ETGs) and 2011 composite ETGs (located in the composite region on the BPT diagram) from the catalog of the Sloan Digital Sky Survey Data Release 7 MPA-JHU emission-line measurements. I compare the properties of both ETG samples and investigate their compositions, stellar masses, specific star formation rates (sSFRs), and excitation mechanisms. Compared with star-forming ETGs, composite ETGs have higher stellar mass and lower sSFR. In the stellar mass and u − r color diagram, more than 60% of star-forming ETGs and composite ETGs are located in the green valley, showing that the two ETG samples may have experienced star formation and that ∼17% of star-forming ETGs lie in the blue cloud, while ∼30% of composite ETGs lie in the red sequence. In the [N II]/Hα versus EWHα (the Hα equivalent width) diagram, all star-forming ETGs and most of the composite ETGs are located in the star-forming galaxy region, and composite ETGs have lower EWHα than their counterparts. We show the relations between 12+log(O/H) and log(N/O) for both ETG samples, and suggest that nitrogen production of some star-forming ETGs can be explained by the evolution scheme of Coziol et al., while the prodution of composite ETGs may be a consequence of the inflowing of metal-poor gas and these more evolved massive galaxies.
DNA hydrogel to improve solution-gate graphene field effect transistor in all-solid-state

The solution-gate graphene field effect transistor (Sg-GFET), as a popular sensing platform, its applications are still hindered by the deficiency in all-solid-state, due to the dependence on liquid-state gate-dielectric. Inspired by DNA hydrogel which can provide microporous architecture to accommodate the fluidic analyte, moreover, its combination with graphene is believed to foster electron transport in the field of electrochemistry. We are interested to take advantage of DNA hydrogel's solid-state and capability for holding solution, and investigate whether it can replace the traditional solution. So pure DNA hydrogel, their complexes with GO (GO/DNA hydrogel) and RGO (RGO/DNA hydrogel) are studied herein. Their micro-porous 3D morphologies are demonstrated, their influences on the electrical characteristics of GFETs are carefully examined and proved to be able to maintain the typical bipolarity of Sg-GFET, firstly. Then, pure DNA hydrogel and GO/DNA hydrogel are selected as the optimized gate-dielectrics, because of their renewability after dehydration. Furthermore, by using aptamer-based heavy metal ions (Pb2+ and Hg2+) detections as proof-of-concept, the strategies for building the sensing platform based on the optimized hydrogel dielectric-gated GFETs are studied. It is found, for the purpose of substituting fluidic dielectric in traditional Sg-GFET, the scheme of directly mounting aptamer on graphene channel and coating pure DNA hydrogel on it is demonstrated to be better than the strategies of using GO/DNA hydrogel and hybriding aptamer probes in hydrogel scaﬀold. It is explained according to surface charge sensing mechanism. At last, the performances of the sensing platform based on the proposed DNA hydrogel gated GFETs are testified by the detections and selectivity examinations for Pb2+ and Hg2+. Conclusively, pure DNA hydrogel is expected to be a promising candidate in the future all-solid-state Sg-GFET.
GaAs acoustic-surface-wave propagation losses at 1 GHz

Measurements of acoustic-surface wave propagation losses in air have yielded the following for GaAs at 1 GHz: 3.62 dB/μs for the [211] cut, [111] propagating orientation, and 4.22 dB/μs for the [110] cut, [100] propagating orientation. Air loading for these two cuts is 0.27 and 0.40 dB/μs, respectively. These results are independent of surface quality for defects up to 0.04 wavelengths in size.
A spatial ecological analysis of the reintroduction of the Eurasian beaver

As ‘nature’s ecological engineers’ beavers can intentionally modify their habitat by building structures. This ability can have wider environmental benefits, including benefits for other habitats and species. However, this ability to modify the environment can sometimes be destructive, bringing beavers into conflict with land managers and others. To understand the complex connections between Eurasian beavers and ecosystems, this study was based on R language analysis tool that used land cover types, river network distribution and observational record studies of Eurasian beavers to find their most preferred environmental resources and potential habitats. The results found that reintroduced Eurasian beavers have a high potential for settlement and dispersal in restored areas.

Predatory Publications in the Era of the Internet and Technology: Open Access Publications are at Risk

This article is intended to highlight the issue of predatory journals and how they have been used to degrade the open-access journals to be perceived as predatory ones. Since many of the predatory journals are available for readers free of cost over the internet (which is among one of the many features of open-access journals/publications), the international wave of the scientific community against predatory journals stigmatized and victimized the entire open-access model of scientific publication to be perceived as substandard quality. This article critically analyzes the definitions of predatory journals and identified key characteristics of predatory journals. It is observed that lack of peer-review and charging high Article Processing Charges (APC) from authors are the two most common features of predatory journals, whereas open-access journals strictly adhere to peer-review criteria and have a clear guideline and information about the article processing fee. Knowingly or unknowingly, several authors mentioned that predatory journals are mostly open access, an overgeneralization of the author pay model upon which open access lies. Peer-review is an essential component of open access journals but not predatory journals; thus, considering predatory journals under the broad notion of open-access model of publication is unfair, stigmatizing and victimizing the open-access journals and keeping them at risk of degradation. Associating open-access journals with predatory ones is a nuisance as both have different aims, modus-operandi, and quality concerns. Therefore, there is a dire need to make policies to discourage predatory practices without victimizing the noble idea of open-access journals/publications. Keywords: open access, predatory journals, article processing charges, peer-review
The Long-run Development Impacts of Agricultural Productivity Gains: Evidence from Irrigation Canals in India ∗

How do investments in agricultural productivity translate into development and structural transformation? An extensive literature has addressed these questions, dating back to the earliest days of development economics. In this paper, we estimate the long-run impacts of India’s irrigation canals, which span over 300,000 km and deliver water to over 100,000 villages. Drawing on high-resolution data on every household, firm, village, and town in India, we use three empirical strategies to characterize the direct and spillover effects of large increases in agricultural productivity. First, we exploit the gravity-driven nature of canal irrigation in a regression discontinuity design with elevation as the running variable. Second, we study spillovers by comparing untreated settlements close to canals to those farther away. Third, we use a 100-year panel of urban populations to estimate the effects of canals on regional urbanization. In the long run, canal access drives substantially higher irrigation intensity and land productivity. These changes result in higher population density, but treated areas experience no structural transformation: there are no changes in the share of the workforce outside of agriculture, or even in agro-processing. Consumption gains accrue only to landowners; we estimate a tight null effect on the consumption of the 60% of the population with little or no land. Structural transformation does occur, but through the growth of regional towns rather than through sectoral reallocation of labor within treated villages or their near neighbors. Our findings are consistent with a model where labor is mobile in the long run, and where urban areas have productivity advantages that cause most non-farm growth to occur in towns. In the long run, the substantial productivity effects of canals were equilibrated through the movement of labor across space rather than within locations across sectors.
EFFECT OF PEA PROTEIN ISOLATE, CARBOXYMETHYL CELLULOSE, PECTIN AND THEIR INTERACTION ON PHYSICOCHEMICAL AND OXIDATIVE STABILITY OF OIL-IN-WATER EMULSIONS NG PEI QI*, NOR HAYATI IBRAHIM AND AZLIN SHAFRINA HASIM

Biopolymer interaction in oil-in-water (o/w) emulsions has been demonstrated to positively modify the emulsion physicochemical properties which lead to desirable stability. The present work focused on the effect of pea protein isolate (PPI), pectin, carboxymethyl cellulose (CMC) and their interaction on physicochemical properties and oxidative stability of o/w emulsions using a mixture design approach. The emulsions were prepared with 40 % sunflower oil stabilized with 1 % of PPI, pectin and CMC, respectively, as well as their mixtures according to a simplex-centroid design (10 points). The pH values for all emulsions were within acidic condition (3.22 to 4.66) and increased significantly (p<0.05) as the PPI-CMC level increased. Regression modelling revealed that ternary mixture of PPI-pectin-CMC had the strongest significant (p<0.05) synergism on 2,2-diphenyl-1picrylhydrazyl (DPPH) scavenging activity (85.06 to 91.17 %). Besides, interaction between PPI and CMC significantly (p<0.05) reduced the interfacial tension and at the same time thickened the interfacial membrane to provide the emulsion with desirable small droplet size (10.56 μm). This synergistic interaction effect also significantly (p<0.05) improved oxidative stability of the emulsion resulting in low total oxidation value (<7) due to decreased oxygen transportation rate across the thick interfacial membrane surrounding the emulsion droplets. Moreover, with high coefficients of determination (R > 96%) and insignificant lack of fit (p>0.05) of the fitted models, this study also proved that the mixture design with regression modelling was useful in elucidating PPI, CMC and pectin interactions and also able to empirically predict the responses to any blend of combination of the components.
Nongeometric Building Information Needs Assessment for Facilities Management

AbstractBuilding information modeling (BIM) tools hold promise for owners in terms of collecting the information needed for facility operations. The introduction of BIM technology has increased the need for project teams to deliver information earlier in the project timeline. BIM has been a catalyst for process change in the architecture, engineering, and construction (AEC) industry in terms of earlier decision making and in identifying the need for more precise and accurate information throughout the design and construction process. Because of the use of collaborative project delivery methods, and the owner’s participation on the project team, the same catalyst is now forcing owners to decide and specify in more detail their informational needs and deliverables. To date, owners are dependent on broad recommendations regarding what information they should collect as well as what methods may be used to collect it. To assist owners with specific recommendations, this study examined a microlevel view of the .
ANALYSIS COMPARING PERFORMANCE OF A CONVENTIONAL SHELL AND TUBE HEAT EXCHANGER USING KERN, BELL AND BELL DELAWARE METHOD

The transfer of heat to and from process fluids is an essential part of most of the chemical processes. Therefore, heat exchangers (HEs) are used extensively and regularly in process and allied industries and are very important during design and operation. The most commonly used type of HE is the shell and tube heat exchanger. In the present study, a comparative analysis of a water to water STHE wherein, hot water flows inside the tubes and cold water inside the shell is made, to study and analyze the heat transfer coefficient and pressure drops for different mass flow rates and inlet and outlet temperatures, using Kern, Bell and Bell Delaware methods. This paper purely aims at studying and comparing different methods of STHE and bringing out which method is better for adopting in shell side calculations.
Imbalanced segregation of recombinant haplotypes in hybrid populations reveals inter-and 1 intrachromosomal

9 Dobzhansky-Muller incompatibilities (DMIs) are a major component of reproductive isolation between 10 species. DMIs imply negative epistasis, exposed when two diverged populations hybridize. Mapping the 11 locations of DMIs has largely relied on classical genetic mapping. Approaches to date are hampered by 12 low power and the challenge of identifying DMI loci on the same chromosome, because strong initial 13 linkage of parental haplotypes weakens statistical tests. Here, we propose new statistics to infer negative 14 epistasis from haplotype frequencies in hybrid populations. When two divergent populations hybridize, 15 the variance of the number of heterozygous sites at two loci decreases faster with time at DMI loci than at 16 random pairs of loci. If two populations hybridize at near-even admixture proportions, the deviation of the 17 observed variance from its expectation becomes negative for the DMI pair. This negative deviation 18 enables us to detect intermediate to strong negative epistasis both within and between chromosomes. The 19 detection window depends on the demographic scenario, the recombination rate, and the strength of 20 epistasis. When the initial proportion of the two parental populations is uneven, only strong DMIs can be 21 detected with our method unless migration prevents parental haplotypes from being lost. We use the new 22 statistics to infer candidate DMIs from three hybrid populations of swordtail fish. We identify numerous 23 new DMI candidates, some of which are inferred to interact with several loci within and between 24 chromosomes. Moreover, we discuss our results in the context of an expected enrichment in 25 intrachromosomal over interchromosomal DMIs. 26
COMPARISON OF MUSCLE ACTIVATION AND PERFORMANCE DURING 6 RM, TWO- LEGGED FREE-WEIGHT SQUATS PRIMERJAVA MIŠIČNE AKTIVACIJE IN USPEŠNOSTI PRI POČEPIH NA OBEH NOGAH PRI DVIGOVANJU UTEŽI 6-RM Roland van den Tillaar 1

The aim of this study was to compare 6-RM performance and muscle activation in two-legged, free-weight squats. Fifteen resistance-training males (age 24 ± 4 years, body mass 82 ± 11 kg, height 179 ± 6 cm) with 6 ± 3 years of resistance-training experience conducted one set of 6 RM. The barbell kinematics and EMG activity of vastus lateralis, vastus medialis, rectus femoris, biceps femoris and erector spinae were measured in the downward and upward part of each of the six repetitions. The total lifting time increased, but only from repetition 2 and 3 to 4 and later. Further, the peak and average velocity in the upward part decreased from repetition 4 and later. For the downward part, only repetition 1 showed significantly longer lifting times and lower peak velocity compared with the other five repetitions. The EMG activity of most muscles was significantly lower in the first two repetitions compared with the other repetitions. There was similar muscle activity in the final four repetitions. To avoid fatigue (decreased barbell velocity) while ensuring maximal EMG activation during training, we recommend only performing 3 to 4 of the six repetitions with the 6-RM load since similar muscle activity was observed after repetition 4. Therefore, to avoid fatigue in the final repetitions, the number of sets performed with a high level of quality in each session may be increased as well as the training frequency, which may help athletes gain muscle strength.
HIV_A_336886 1079..1090

School of Health Sciences, University of KwaZulu-Natal, Durban, South Africa Introduction: Improvements in physical, mental, and overall quality of life are well documented in younger HIV populations who exercise. Exercise guidelines exist for younger HIV populations, but none for older people living with HIV (OPLWH), especially 50 years of age and older. Our aim was to map the existing literature on the effects of exercise and physical activity prescriptions for OPLWH. Methods: We conducted a scoping review using the methodological framework proposed by the Joanna Briggs Institute. Online searches on five research databases yielded 503 published articles. Fifteen studies met the study’s inclusion criteria. Results: The most commonly used parameters of exercise included aerobic and strength training, as well as a combination of both. The physical, psychological and Quality of Life (QoL) impact of physical activity and its effect on OPLWH is evidently beneficial. Overall, a positive correlation between exercise and physical, mental and functional status was observed. No adverse side effects, or safety and efficacy concerns, during the use of exercise were reported. Conclusion: This review confirms the dearth of evidence on physical activity and exercise in the context of OPLWH. Of greater concern is the fact that there were no studies conducted in sub-Saharan Africa, the global region with by far the highest HIV burden.
Sine-triangle vs. space vector modulation for three-level PWM voltage source inverters

This paper studies the inherent relations between sine-triangle and space vector PWM schemes for three-level voltage source inverters. It is shown that the two schemes can function equivalently through proper selection of common mode injections in the case of sine-triangle modulation, or dwell times in equivalent redundant switching states in the case of space vector modulation. Simulation and measurement results illustrate that understanding of these relations can lead to a more efficient and flexible three-level modulator with desired or optimal performance.

Studies on the association between dietary salt intake and the glycemic response of T2D are lacking in China. The aim was to investigate the association between the levels of dietary salt intake and the plasma glucose, insulin and hemoglobin A1c (HbA1c) levels in T2D patients. Methods: Patients with T2D, who accepted management and treatment by the National Standardized Metabolic Disease Management Center at Ningbo First Hospital from March 2018 to January 2020, were included in this study. Dietary salt intake was assessed through a standardized food frequency questionnaire. Anthropometry, blood pressure and biomarkers were measured by well-trained endocrinology nurses. Generalized linear models (GLMs) were used to examine the associations. Results: A total of 1145 eligible T2D patients with a mean age of 51.4 years were included in the study. Fasting plasma glucose (FPG), 2-hour postprandial plasma glucose and 2-hour postprandial insulin were significantly increased across dietary salt categories. The GLMs further showed that dietary salt intake >8 g/day was positively associated with FPG and HbA1c. Conclusion: Higher daily salt intake was found to be associated with FPG and HbA1c in T2D patients. Lifestyle education and promotion of salt reduction should be provided to T2D patients.
Covid-19 and the Forces Behind Social Unrest

The unprecedented consequences of the Covid-19 pandemic have raised concerns about intensified social unrest, but evidence for such a link and the underlying channels is still lacking. We use a unique combination of nationally representative survey data, event data on social unrest, and data on Covid-19 fatalities and unemployment at a weekly resolution to investigate the forces behind social unrest in the context of the strains on public health and the economy due to the pandemic in the USA. The results show that pandemic-related unemployment and Covid-19 fatalities intensified negative emotional stress and led to a deterioration of economic confidence among individuals. The prevalence of negative emotional stress, particularly in economically strained and politically polarized environments, was, in turn, associated with intensified social unrest as measured by political protests. No such link is found for economic perceptions. economic shocks | Covid-19 | civil unrest | political polarization Contact: JKU University of Linz, Mario.Lackner@jku.at Corresponding author.

PHYTOTOXIC ACTIVITY OF GERANIOL-TREATED LEMONGRASS LEAF MULCH AGAINST COMMON WEEDS IN NURSERIES

Hand weeding continues to be one of the most laborious aspects of nursery maintenance. Oxygenated monoterpene, an important group of secondary metabolite found in essential oils, has a potential herbicidal activity that could be exploited as natural herbicide whereas organic mulch could delay weed emergence. Thus, this study aimed to examine the phytotoxicity of geraniol, an oxygenated monoterpene compound, in combination with lemongrass leaf mulch against three common weeds, Eleusine indica (grass), Cyperus distans (sedge), and Tridax procumbens (broadleaf). Greenhouse experiments were carried out by treating 4.0 t/ha lemongrass leaf mulch with 7.5% (v/v) geraniol compound. The pretreated mulch acted synergistically and inhibited the emergence and shoot growth of T. procumbens completely. However, the pretreated mulch exhibited a moderate inhibitory effect on C. distans emergence and growth. Geraniol-treated lemongrass leaf mulch acted synergistically and inhibited the emergence of E. indica by 72%, but it acted antagonistically and caused a 45% reduction of shoot biomass. The present findings suggest that geraniol-treated lemongrass leaf mulch has potent herbicidal activity but its phytotoxic effect is species-dependent.
