Published: April 2021

Penelitian ini bertujuan untuk mengetahui variabel motivasi, variabel supervisor dan variabel lingkungan

kerja yang baik dapat secara signifikan mempengaruhi disiplin kerja dan kinerja karyawan. Teknik

pengambilan sampel adalah total sampling. Kuesioner menggunakan skala Likert dan data yang

dikumpulkan akan diproses menggunakan analisis regresi linier berganda. Dalam penelitian ini sampel

diambil secara acak, total 45 (empat puluh lima) karyawan atau 10,84% dari populasi 415 orang. Sampel

tersebut representatif karena mewakili 5 (lima) karakteristik berdasarkan proporsi, posisi, kelas, jenis

kelamin dan unit kerja. Hasil pengamatan dengan menggunakan analisis deskriptif menunjukkan bahwa

antara motivasi kerja karyawan (variabel X1) dengan pengawasan dari atasan (variabel X2) berdasarkan

kriteria dari Guilford, koefisien korelasi 0,47 termasuk korelasi rendah. Dengan mengkuadratkan (rX2X2

2) kekuatan hubungan dapat diketahui, yaitu (0,47) 2 = 0,22 dan dikalikan dengan 100% hingga 22%. Ini

berarti bahwa variabel motivasi karyawan dapat ditentukan sebesar 22% oleh variabel pengawasan atau

variabel motivasi karyawan yang dicapai sebesar 22% adalah karena variabel penyelia sedangkan sisanya

78% adalah pengaruh variabel lain seperti variabel lingkungan kerja. Variabel pengawasan, motivasi, dan

lingkungan kerja yang baik dinyatakan memiliki pengaruh terhadap kinerja karyawan (Y). Ini berarti,

setiap kali ada peningkatan motivasi yang didukung oleh pengawasan penyelia dan lingkungan kerja yang

baik akan meningkatkan kinerja karyawan.

Published: April 2021

The study examines the role of Enashma traditional conflict resolution mechanism in handling conflict to maintain peace and stability. To realize the intended objectives, the study utilized case-study research approach with qualitative research method and the data were collected using observation, interview, focused-group discussion and document analysis. The data collected were analyzed and interpreted through word description and narration. According to the data obtained from the interview and focus group discussion, Enashma traditional conflict resolution mechanism has several advantages over the state law. Some of the advantages are restorative capacity, accessibility, revealing crime committed without witness and its acceptability. Paradoxically, the exclusion of women in the system, no standardized mechanism to fix payment of compensation for different conflicts, lack of supportive and strengthening measures from the government and lack of office for local elders are the major weakness of the institution as the information obtained from key informants. Therefore, the study recommended that all the stakeholders should be responsible tosolve the weakness of Enashma traditional conflict resolution mechanism in the study area.

Background and objectives: Helicobacter pylori infection is suspected to be associated with extra-gastrointestinal disorders such as diabetes mellitus (DM). It is still a subject of investigation whether H. pylori has a pathogenic role on DM or diabetic patients have an increased susceptibility to H. pylori infection. The aim of the present study was to find out the rate of H. pylori infection in individuals with and without DM.

Materials and methods: The study was conducted on 72 diabetic and 19 non-diabetic adult individuals with dyspeptic symptoms attending the BIRDEM General Hospital for diagnostic endoscopy. All cases were tested for H. pylori stool antigen by rapid immunochromatographic test (ICT), urease production in biopsy samples by rapid urease test (RUT), and serum anti-H. pylori IgA and anti-CagA IgG antibodies by enzyme-linked immunosorbent assay (ELISA). Any case that had peptic ulcer/erosion and was positive for H. pylori stool antigen or rapid urease test (RUT) was defined as H. pylori positive case.

Results: There was no significant (p=0.095) difference in H. pylori infection between diabetics and non-diabetics (68.1% vs 47.4%). Presence of ulcer and erosion were not significantly different among diabetics and non-diabetics. Anti-H. pylori IgA positivity rate in H. pylori positive diabetic and non-diabetic cases were 65.3% and 55.6% (p=0.575) respectively while anti-CagA IgG rate in those cases were 46.9% and 66.7% (p=0.276) respectively.

Conclusion: The present study did not reveal any significant difference in H. pylori infection between individuals with and without DM having peptic ulcer/erosion.

Published: April 2021

Edible flowers are trend in the novel food sector since they may be inserted in natural, health and eco-innovation approach. However, there is little information in literature about consumers perception about them, mainly in western society. Thus, the objective of the present work is to evaluate Brazilians perception about roses, hibiscus, ipê and pansy as edible flowers. An online survey was applied using a free word association methodology and a check-all-that-apply for their application in gastronomy. Results from word association show that all flowers were highly associated to positive attitudes and feelings, appearance and application aspects. Environmental words were also highlighted within the responses. These features were significantly related to frequency of buying new foods and show up as important characteristics to be explored for enhance edible flowers popularity. For application of them within food formulations, rose and hibiscus were tracked to tea, jam, bread and cookies utilization, meanwhile pansy to salads. Ipê was not related to none of gastronomy applications. Results indicate that knowledge of tangible and intangible flowers features, such as functional, environmental and application aspects can change and enhance change consumers perception and willingness to try these non-conventional edible plants. Deeper studies about people perception and attitude towards edible flowers are necessary to evaluate the influence of eating and shopping habits, neophobic behavior and others on their consumption.

Published: April 2021

A aroeira-do-sertão é uma espécie arbórea, presente em várias regiões do Brasil, utilizada especialmente no Nordeste com finalidades medicinais. Sementes diásporos das espécies que se desenvolvem em regiões áridas e semiáridas, como é o caso das espécies da Caatinga, são acometidas a situações inadequadas para sua germinação, como temperaturas elevadas, grandes concentrações de sais no solo e deficiência hídrica. Este trabalho objetivou investigar o comportamento dos diásporos de Astronium urundeuva Fr. (M. Allemão) Engl. previamente submetidos à condições adversas, visando uma forma de resiliência da espécie perante tais condições. Alguns autores comprovaram melhoras germinativas e do vigor das plântulas, quando os diásporos foram submetidos ao condicionamento fisiológico, tanto por meio da hidratação em água como em soluções osmóticas, sugerindo a hipótese de que os diásporos condicionados e depois expostos a estresses abióticos, possam ter sua qualidade recuperada. Há poucos trabalhos que apontem o condicionamento como uma técnica atenuadora dos efeitos ocasionados por condições adversas em diásporos de A. urundeuva, por outro lado, em alguns casos, demostra ser uma excelente técnica para aumentar a germinabilidade e vigor da espécie.

Published: April 2021

Ora-pro-nóbis (Pereskia aculeata) é olerícola considerada uma hortaliça não convencional. A procura por este tipo de alimento vem apresentando uma crescente tendência nos mercados. Porém, a carência de informações técnicas para o cultivo de ora-pro-nóbis limita a sua expansão como cultura comercial. O objetivo deste trabalho foi avaliar o efeito do plantio horizontal de 2 tipos de miniestacas de ora-pro-nóbis diretamente em canteiro, em diferentes densidades de plantio, como nova prática de propagação para implantação de sistema de produção. Foi instalado um experimento em canteiro a céu aberto no Setor de Olericultura da Fazenda Experimental do Canguiri (Pinhais-PR), pertencente à UFPR. Os tratamentos utilizados foram: 1) miniestaca semilenhosa de 5 cm plantadas no espaçamento de 10 cm entre linhas, 2) miniestaca semilenhosa de 5 cm plantadas no espaçamento de 20 cm, 3) miniestaca semilenhosa de 10 cm plantadas no espaçamento de 10 cm, 4) miniestaca semilenhosa de 10 cm plantadas no espaçamento de 20 cm e 5) miniestaca lenhosa de 10 cm plantadas no espaçamento de 10 cm. Aos 60 dias após o plantio, as miniestacas foram desplantadas, avaliadas e os principais resultados demonstraram que no geral as miniestacas lenhosas obtiveram melhor estabelecimento no canteiro (66,7 %), maior massa fresca (566,1 g m-2), massa seca (54,0 g m-2) e teor de massa seca (12,0 %) dos brotos e maior brotação (41,6 brotos m-2).

Factors Controlling Coral Skeletal U/Ca Ratios with Implications for their Use as a Proxy for Past Ocean Conditions
Authors: Patterson Emily , Eanes Spencer , Lancrete Penelope , Gothman Anne , Roback Paul
Published: April 2021

Seawater temperature, salinity and carbonate chemistry have been shown to influence the uranium/calcium (U/Ca) ratios of scleractinian coral skeletons. This apparent sensitivity of U/Ca to multiple environmental parameters calls into question whether there is one environmental variable that most strongly controls coral U/Ca, and whether U/Ca can be straightforwardly applied as a paleoenvironmental proxy due to the tendency of environmental variables to covary in space and time. In this study, uranium concentration data from an existing compilation of tropical scleractinian coral U-series measurements is paired with environmental data from the World Ocean Atlas (WOA) and the Global Ocean Data Analysis Project (GLODAP) to examine the sensitivity of coral skeletal U/Ca to multiple seawater properties including temperature, salinity, pH, and saturation state. First, univariate linear regressions and multiple linear regressions were used to compare relationships between uranium and environmental parameters in the dataset with relationships observed in previous studies. Next, principal component analysis and regularized regression were used to identify the most likely predictors of coral U/Ca in order to create a multiple linear regression model. Results indicate that pH, Ω, alkalinity, and temperature are all significant predictors of uranium concentrations in coral. The magnitude and strength of relationships between U/Ca and environmental variables also differ across different genera. Seawater properties with strong correlations and small ranges make interpretation of these results difficult. However, results of these analyses indicate that U/Ca is dependent on multiple environmental parameters and that previously developed univariate regressions may be insufficient to characterize the full range of variables that influence coral [238U].

Published: April 2021

The utilization of recycled aggregates made from construction wastes and recycled rubber made from waste tires is an effective method to realize the sustainable development. Thus, this study aims to determine the feasibility of using recycled aggregate concrete containing rubber, named rubberized recycled aggregate concrete (RRAC) as a new type of green-building material. The experimental carbon emissions test verified RRAC as a low-carbon material. In addition, the residual mechanical properties of RRAC were investigated under elevated temperatures. After exposure at 200, 400, and 600 C for 60 min, the stress−strain curve, compressive strength, energy absorption capacity, and spalling resistance of RRAC with recycled aggregate replacement ratios of 50 and 100%, rubber contents of 0, 5, 10, and 15% were explored with microstructural analysis. Moreover, empirical models were proposed to describe the effects of heated temperatures and rubber contents on the stress–strain relationship of RRAC. The results indicated that the rubber particles could reduce the spalling of specimens based on the vapor pressure theory. Therefore, this study provided scientific guidance for the design of structures made with RRAC for resisting high temperatures.
Possible Tracheal Relaxant and Antimicrobial Effects of the Essential Oil of Ethiopian Thyme Species (Thymus serrulatus Hochst. ex Benth.): A Multiple Mechanistic Approach

Published: April 2021

The genus Thymus is traditionally used for the treatment of hyperactive airways complaints. The purpose of the current study is to investigate the potential tracheal relaxant effect and possible mechanism(s) of the essential oil of Thymus serrulatus (TS Oil) in isolated guinea pig tracheal tissues. The essential oil was obtained from the fresh erial parts of Thymus serrulatus, and its phyto-components were identified by GC-MS analysis. Guinea pig tracheal preparations were used for testing the tracheal relaxant effect of TS Oil with the determination of the mechanism(s) involved in this relaxation. GC-MS findings reveal that terpenes, fragrance constituents, saponins, and higher fatty acids are present in TS Oil. In isolated guinea pig trachea, TS Oil inhibited carbachol (CCh, 1 µM) and K+ (80 mM)-induced contractions in a pattern similar to that of dicyclomine. TS Oil, at 0.3 mg/ml, shifted parallel CCh-curves towards the right, followed by a non-parallel shift at higher concentration (1 mg/ml), thus suppressing maximum response in the same manner as produced by dicyclomine. Pretreatment of tissues with TS Oil (1 and 3 mg/ml) also produced a rightward shift of Ca++ concentration-response curves (CRCs) in the same manner as caused by verapamil. Further, TS Oil at low concentrations (0.3 and 1 mg/ml) shifted isoprenaline-induced inhibitory CRCs towards the left and increased cAMP levels in isolated tracheal homogenates similar to papaverine, a phosphodiesterase (PDE) inhibitor. In the antimicrobial assay performed by the agar well diffusion method, TS Oil was found most active against Candida albicans and Staphylococcus aureus where the zone of inhibition measured was 28 mm. Additionally, there was little difference between standard strains of gram-positive and gram-negative bacteria. However, methicillin-resistant S. aureus (MRSA) showed a small zone of inhibition as compared to standard strains (22 mm). From these results, it can be concluded that the essential oil of T. serrulatus has the potential to produce antimicrobial effects while causing tracheal relaxation mediated possibly by anticholinergic effects, Ca++ channel blockade, and PDE inhibition whereas additional mechanism(s) cannot be ruled out.

Published: April 2021

The presented communication provides the analysis of entropy generation and heat transport rate in peristalsis of hybrid nanofluid induced by metachronal ciliary beating under magnetic environment for sufficiently large magnetic Reynolds number. Nanoparticles of Cu and Al2O3 are suspended in water. Features of their structures are determined by using long-wavelength approximation with zero Reynolds number. Adams Bashforth method has been applied to compute the results of the flow variables as well as entropy generation number from the formulated differential system which are then interpreted graphically to establish physical significance for different values of physical interest. This investigation reveals that thermal performance of fluid can be boosted by utilizing hybrid nanomaterial about the strength of a wall for stability. Irreversibility analysis ensures that entropy reduced for strong magnetic field while thermal heat generation results in an increase in temperature causing an enhancement in entropy of the system. Error analysis has been performed with reasonably accurate tolerance level. The comparative outcomes of both numerical approaches are presented with plentiful graphical as well as numerical demonstrations which demonstrate the importance in terms of robustness, accuracy and stability.

Authors: Ge Teng , Huang Xing-Huai , Guo Ying-Qing , He Ze-Feng , Hu Zhong-Wei
Published: April 2021

This paper aims to develop viscoelastic dampers, which can effectively suppress vibration in a wide frequency range. First, several viscoelastic materials for damping performance were selected, and different batches of cylindrical viscoelastic dampers were fabricated by overall vulcanization. Second, the dynamic mechanical properties of the cylindrical viscoelastic dampers under different amplitudes and frequencies are tested, and the hysteretic curves under different loading conditions are obtained. Finally, by calculating the dynamic mechanical properties of the cylindrical viscoelastic dampers, the energy dissipation performance of these different batches of viscoelastic dampers is compared and analyzed. The experimental results show that the cylindrical viscoelastic damper presents a full hysteretic curve in a wide frequency range, in which the maximum loss factor can reach 0.57. Besides, the equivalent stiffness, storage modulus, loss factor, and energy consumption per cycle of the viscoelastic damper raise with the frequency increasing, while the equivalent damping decreases with the increase of frequency. When the displacement increases, the energy consumption per cycle of the viscoelastic damper rises rapidly, and the equivalent stiffness, equivalent damping, storage modulus, and loss factor change slightly.

During the last three decades, like many other Mediterranean states, Spain has intensively promoted the modernization of irrigation, focusing mainly on the introduction of pressurized irrigation systems. Following 30 years of investment, a shift in irrigation policies is needed to solve some of the deficiencies in this modernization process and to incorporate new measures to cope with upcoming challenges generated by international markets, climate change and other social and economic processes. This paper describes and analyses the results of participatory research carried out with the water user associations in the autonomous region of Valencia, in order to define post-modernization irrigation policies. A survey and 24 local workshops involving 304 water user associations were conducted during the irrigation season of 2018 in order to form an assessment of the sector and design new irrigation policies. The results show that after 30 years of important investment, the obsolescence of the infrastructure has become the current main priority, making farmers dependent on public subsidies. New necessities have also emerged, such as renewable energies and nonconventional water resources, which farmers consider indispensable in order to reduce operating costs and guarantee water supply.

Published: April 2021

The main growing regions for winter wheat in the Russian Federation are the North Caucasian, Central Black Earth, and Central agroecological regions. Spring wheat crops dominate in the Urals, Volga region, and Western Siberia. Wheat leaf rust, caused by Puccinia triticina, is an important disease, impacting greatly on wheat production. In Russia, the disease was an annual problem until 2010 but has since been more effectively controlled. However, changes in virulence in pathogen populations may arise from climate change, evolving cropping practices, intense use of chemical protectants, and an increase in the release of resistant cultivars. In the 2000s, the State Register of the Russian Federation included an increase in the number of winter and spring wheat cultivars resistant to leaf rust. However, successful genetic protection requires a diversity of cultivars with different resistance genes (Lr genes). Studies by the All Russian Institute of Plant Protection identified Lr genes in Russian cultivars’ phenotypes and molecular markers. In addition, the prevalence of virulence in pathogen populations was studied and the influence of the cultivar used in wheat production on the changes in these populations was evaluated. This paper reviews research on the genetic diversity of winter and spring wheat cultivars included in the State Register of Russia from 2000 to 2020 and analyzes their impact on the prevalence of virulence in pathogen populations. These data demonstrate the continuous evolution of P. triticina in response to wheat breeding efforts. Populations of the pathogen showed higher variability in regions where pathotype-specific resistance cultivars were commonly grown.

China, as a contrary climate to the Mediterranean-climate region, is massive in planting olive (Olea europaea) cultivation as an important oil crop. Nonetheless, Chinese olive leaves have received little attention and there is little information about the phenols content. Therefore, in this study, a multiple-response optimization was performed to maximize the total phenolic and oleuropein content (TPC and OEC) by ultrasound-assisted extraction, and the aged and young leaves prepared from six Chinese cultivars from January to December were investigated concerning seven main phenolic composition. Under optimal conditions (power 260 W, time 10 min, liquid-solid ratio 30 mL/g, and 50% ethanol), the highest TPC (197.32 mg/g DM) and OEC (74.68 mg/g DM) were obtained. Findings revealed that the optimal olive leaves for phenolic compounds were the young leaves in spring and winter, being oleuropein and luteolin-4′-O-glucoside present in higher level, and the “Koroneiki” and “Jiufeng” cultivars were relatively stable. Furthermore, antioxidant potential of the phenol extract and oleuropein was also evaluated based on the reducing power and scavenging effect on 1,1-diphenyl-2-picrylhydrazyl (DPPH)and superoxide radical assays, and a higher antioxidant effect of oleuropein was observed compared to the phenol extract. In addition, oleuropein showed anticancer activity against HeLa cells, with a minimum inhibitory concentration (EC50) value of 0.19 mg/mL at 48 h. These findings revealed an attractive source of biological substances for further development and utilization of Chinese olive leaves.
Winter Wheat Adaptation to Climate Change in Turkey
Authors: Kaya Yuksel
Published: April 2021

Climate change scenarios reveal that Turkey’s wheat production area is under the combined effects of heat and drought stresses. The adverse effects of climate change have just begun to be experienced in Turkey’s spring and the winter wheat zones. However, climate change is likely to affect the winter wheat zone more severely. Fortunately, there is a fast, repeatable, reliable and relatively affordable way to predict climate change effects on winter wheat (e.g., testing winter wheat in the spring wheat zone). For this purpose, 36 wheat genotypes in total, consisting of 14 spring and 22 winter types, were tested under the field conditions of the Southeastern Anatolia Region, a representative of the spring wheat zone of Turkey, during the two cropping seasons (2017–2018 and 2019–2020). Simultaneous heat (>30 °C) and drought (<40 mm) stresses occurring in May and June during both growing seasons caused drastic losses in winter wheat grain yield and its components. Declines in plant characteristics of winter wheat genotypes, compared to those of spring wheat genotypes using as a control treatment, were determined as follows: 46.3% in grain yield, 23.7% in harvest index, 30.5% in grains per spike and 19.4% in thousand kernel weight, whereas an increase of 282.2% in spike sterility occurred. On the other hand, no substantial changes were observed in plant height (10 cm longer than that of spring wheat) and on days to heading (25 days more than that of spring wheat) of winter wheat genotypes. In general, taller winter wheat genotypes tended to lodge. Meanwhile, it became impossible to avoid the combined effects of heat and drought stresses during anthesis and grain filling periods because the time to heading of winter wheat genotypes could not be shortened significantly. In conclusion, our research findings showed that many winter wheat genotypes would not successfully adapt to climate change. It was determined that specific plant characteristics such as vernalization requirement, photoperiod sensitivity, long phenological duration (lack of earliness per se) and vulnerability to diseases prevailing in the spring wheat zone, made winter wheat difficult to adapt to climate change. The most important strategic step that can be taken to overcome these challenges is that Turkey’s wheat breeding program objectives should be harmonized with the climate change scenarios.

Mesenchymal stem cells (MSCs) showed in vitro mesoderm-lineage differentiation and self-renewal capacity. However, no comparative study was reported on the biological characteristics of stem cells derived from skeletal muscle (SM-MSCs), dermal skin (DS-MSCs), and adipose tissues (A-MSCs) from a single donor in camels. The present study aimed to evaluate the influence of MSCs source on stem cell characteristics. We evaluated proliferation capacity and mesoderm-lineage differentiation potential from SM-MSCs, DS-MSCs, and A-MSCs. They showed spindle-like morphology after homogenization. The proliferation ability was not significantly difference in any of the groups. Furthermore, the portion of the cell cycle and expression of pluripotent markers (Oct4, Sox2, and Nanog) were similar in all cell lines at passage 3. The differentiation capacity of A-MSCs into adipocytes was significantly higher than that of SM-MSCs and DS-MSCs. However, the osteoblast differentiation capacity of A-MSCs was significantly lower than that of SM-MSCs and DS-MSCs. Additionally, after osteoblast differentiation, the alkaline phosphatase (ALP) activity and calcium content significantly decreased in A-MSCs compared to SM-MSCs and DS-MSCs. To the best of our knowledge, we primarily established MSCs from the single camel and demonstrated their comparative characteristics, including expression of pluripotent factors and proliferation, and in vitro differentiation capacity into adipocytes and osteoblasts.

Dietary protein is one of the most important nutritional factors in aquaculture. The aim of this study was to examine the effects of dietary protein levels on the gut microbiome and the liver and serum levels of metabolites in tilapia. Tilapia were fed a diet with a low (20%), moderate (30%), or high (40%) content of crude protein, and the homeostasis of the gut microbiome and metabolic profile of the liver and serum were analyzed. The results showed no significant differences in the diversity and richness of the gut microbiome among the groups; however, there were differences in the microbial composition of the gut. The metabolome analysis of liver samples revealed a difference in the glucose level among the groups, with the highest glucose level in fish fed a high protein diet. In addition, there were significant differences in the levels of tyrosine, guanosine, and inosine among the metabolome analysis of serum samples of these groups. In summary, diets with different protein levels could affect the composition of gut microbiota and the dynamic balance of microbial communities. Dietary protein content can also affect glycolysis and amino acid metabolism in tilapia.

This study determined the contents of cadmium (Cd) in the muscles, ovaries, and eggs of silver female European eels. The analysis of cadmium content was performed on female European eels caught during commercial fishing in freshwater in Warmia and Mazury (Poland), and then subjected to artificial maturation and ovulation processing under controlled conditions. The content of cadmium (Cd) in the tissues was determined by flameless atomic spectrometry using an electrothermal atomizer. The analysis showed statistically significant differences between the cadmium content in the muscles, ovaries, and eggs (p < 0.05) of female European eels. The lowest cadmium content was found in the muscle tissue (0.0012 ± 0.0001 mg kg−1 wet weight) and the highest in eggs (after ovulation) (0.0038 ± 0.0007 mg kg−1 wet weight). Moreover, a relationship was found between the cadmium content in the muscle tissue and the ovaries (R = 0.673; p = 0.0117) in the same fish. The movement of cadmium from tissues to oocytes may indicate a significant problem concerning this heavy metal content in the reproduction of European eel.
