Challenges and Opportunities to Regional Renewal in the European Union

The strength of the 2008 financial and economic crisis and the resulting degree of resilience were heterogeneous among and within the European Union countries. Challenges and opportunities driven by regional-specific differences determined the ability to overshoot the precrisis levels of growth. Focusing upon Nomenclature of Territorial Units for Statistics 2 (NUTS 2) European regions, we explore a novel conceptual framework related to regional economic resilience, namely the renewal capacity. Precisely, we concentrate on the capacity of regional economies to “renew” their growth paths in the labor market in the aftermath of the recent global crisis. We find some well-identified spatial patterns of regional employment renewal and we identify a set of territorial assets that allow regions to bounce back faster and more comprehensively than others to the economic downturn. Furthermore, there are significant differences between the drivers of the regional renewal of Old and New Member States. Our findings suggest potential policy directions at all levels for enhancing regional resilience.
Impact of a Social Constructivist Instructional Strategy on Performance in Algebra with a Focus on Secondary School Students

There have been perennial concerns on the low academic performance of students among researchers and other education stakeholders. Innovative teaching strategies have, therefore, gained prominence in the field of mathematics education. The purpose of this study is to investigate the impact of a social constructivist instructional strategy on students’ performance in algebra. The present study is quasi-experimental, and its type is a posttest control group involving 154 secondary school students that are randomly selected across four intact classes. The random selection of students to treatment and control controls is assumed to improve the validity of the results. Two research questions are raised, and two null hypotheses are formulated and tested at p≤0.05 level of significance. One research instrument, algebra performance test (APT), was developed, pilot-tested (test-retest reliability coefficient of 0.897), and used to measure students’ performance in both treatment and control groups. The data are analyzed using independent sample t-tests. The findings indicate that there are significant differences in the mean performance scores between experimental (mean = 16.05, SD = 2.74) and control (mean = 11.46, SD = 2.49) groups, t(152) = 10.83, p<0.05. These findings may be interpreted to be evidence of the effectiveness of the social constructivist instructional strategy in improving performance in algebra better than the conventional teaching method. Also, a significant difference exists between the mean performance scores of males (mean = 17.83, SD = 2.82) and females (mean = 14.72, SD = 1.77) in the experimental group (t(80) = 6.11, p<0.05). Thus, the effect of the social constructivist instructional strategy on students’ performance in algebra is gender-sensitive. Based on these findings, some recommendations are made to students, teachers, parents, administrators, and other stakeholders.
Identification of Critical Diffuse Pollution Sources in an Ungauged Catchment by Using the Swat Model- A Case Study of Kolleru Lake, East Coast of India

Freshwater ecosystems are facing severe threats from human activities. As a consequence of this, they can get disturbed. In developing countries, like India, freshwater lakes are endangered primarily by agricultural activities, which often accelerate erosion and the runoff. The massive application of pesticides and chemical fertilizers to agricultural lands is one of the reasons for eutrophication in Kolleru Lake. The different natural and anthropogenic influences increase the highly complex ecosystem of the lake. Therefore, the objectives of this study are to ascertain the priority control areas, aiming at socio-economic development for the protection of the lake water quality by applying the Best Management Practices (BMPs). For this purpose, the Soil and Water Assessment Tool (SWAT) was used to identify the critical areas of the lake's catchment in terms of pollution from agricultural runoff into the tributaries of the Kolleru Lake and the lake itself. The results demonstrated that the diffuse pollution load in the western and downstream watersheds the highest and that agricultural land was the primary pollutant source besides the accumulation of nutrients in the downstream areas. The differences in the sub-basin Original Research Article Kolli et al.; AJGR, 3(2): 53-68, 2020; Article no.AJGR. 58126 54 loads were observed in the catchment mainly depends on the topographic features, soil properties, land use, vegetation, and drainage patterns. From where the major outlet sub-basin has the highest accumulation of nitrate-nitrogen (NO3_N), and total phosphorus (TP) emissions were quantified. The temporal distribution of runoff and diffuse sources were estimated from 2008 – 2014. The runoff mainly governed diffuse pollution was found to be a significant contributing factor to the lake. Further, suggestions were provided for the implementation of agricultural management practices to minimize pollution levels.
The Acute Influence of Running-Induced Fatigue on the Performance and Biomechanics of a Countermovement Jump

Lower limb kinematics and kinetics during the landing phase of jumping might change because of localized muscle fatigue. This study aimed to investigate the acute influence of running-induced fatigue on the performance and lower limb kinematics and kinetics of a countermovement jump. A running-induced fatigue protocol was applied to fifteen male subjects. Participants were asked to perform three successful countermovement jumps before and after fatigue. Kinematic and kinetic data were collected to compare any fatigue influences. Wilcoxon signed-rank tests and paired-sample t-tests were used to analyze the data. Running-induced fatigue did not significantly change vertical jump height and peak vertical ground reaction forces (GRF) during the push-off and landing phases. Lower limb biomechanics significantly changed, especially kinematic parameters. During the push-off phase, fatigue resulted in an increased ankle peak inversion angle, knee minimal flexion angle, knee peak abduction angle, and hip peak flexion moment. In addition, the range of motion (ROM) of the ankle and knee joints in the frontal plane was also increased. Certain parameters decreased as a result of fatigue, such as the ankle peak internal rotation angle, hip peak abduction angle, the ROM of the ankle joint in the sagittal plane, and ROM of the hip joint in the frontal plane. During the landing phase, the peak inversion angle and peak external rotation angle of the ankle joint, peak abduction angle of the knee and hip joint, ROM of the ankle joint in the horizontal plane, ROM of the ankle and knee joint in the frontal plane were all increased as a result of fatigue. The knee peak flexion moment and hip peak extension moment, however, were decreased. Under fatigue conditions, lower limb kinetics and kinematics were changed during both the push-off and landing phases. More attention should be focused on the landing phase and the last period of the push-off phase due to potentially higher risks of injury. The findings of the current study may be beneficial to athletes and coaches in preventing jumping related injuries.
Hysterolaparoscopy as a one-time approach in infertility: a prospective study

Infertility is one of the most important but least taken care of reproductive health problems in developing countries. It is frequently considered a tragedy and a curse for the couple, impacting on the entire family and the community. The prevalence of infertility ranges from 3.5% to 16.7% in more developed nations and from 6.9% to 9.3% in less developed nations, with an estimated overall median prevalence of 9%.
Characteristics of Carbonaceous Matter in Aerosol from Selected Urban and Rural Areas of Southern Poland

The purpose of this study is to obtain a detailed picture of the spatial and seasonal variability of carbonaceous matter in southern Poland. Particulate matter (PM) samples from eight selected urban and rural background sites were analyzed for organic carbon (OC) and elemental carbon (EC) (thermal-optical method, “eusaar_2” protocol), and the content of secondary (SOC) and primary organic carbon (POC) was estimated. The OC and EC dynamics were further studied using each of the thermally-derived carbon fractions (OC1–4, PC, and EC1–4). Clear spatiotemporal variability of carbonaceous compounds concentrations was observed, with higher levels recorded during the heating season. The considered measurement sites differed particularly in the shares of SOC and POC, with higher values of POC contents especially in rural areas. In terms of the content of carbon fractions, the analyzed sites showed roughly the same characteristics, with PC, OC4, and OC2 as dominant fractions of OC and with clear dominance of EC3 and EC2 over other EC fractions. The results obtained as part of this work may be a valuable source of information about the actual status of the carbonaceous matter, which remains one of the least known components of atmospheric PM.
Evoking re-cognition through embodied enquiry: using drama-based methods to re-script storylines of gendered violence

Abstract In this paper I analyse the influence of drama-based learning activities in an education encounter exploring an instance of gendered violence. I use data stories to chart the multiple material, social, and historical influences that emanated within a role-played act of violence by a father upon his daughter following her transgression of the standards of pre-marital sexual purity held within a strongly religious community. I call upon Butler’s argument, that to understand an act of violence, one must engage with the conditions which permit the act, rather than just the act itself. I use the construct of the assemblage as offered by Deleuze and Guattari to trace the affective forces produced within the learning activities used to examine this enactment. I find that the drama-based activities were productive in opening conditions of possibility when they shifted the genre rules that had limited what it was permissible to feel, say and do as a recognisable masculine subject, and when they offered alternative modalities through which to articulate the multiplicity of possible desires, beliefs, fears and hopes at work within the Father-Daughter relationship.
Tuning network dynamics from criticality to the chaotic balanced state

According to many experimental observations, neurons in cerebral cortex tend to operate in an asynchronous regime, firing independently of each other. In contrast, many other experimental observations reveal cortical population firing dynamics that are relatively coordinated and occasionally synchronous. These discrepant observations have naturally led to a lively debate surrounding discrepant hypotheses. A commonly hypothesized explanation of asynchronous firing is that excitatory and inhibitory neurons are precisely correlated, nearly canceling each other, resulting in the so-called ‘chaotic balanced state’. On the other hand, the ‘criticality’ hypothesis posits an explanation of the more coordinated state that also requires a certain balance of excitatory and inhibitory interactions. Both hypotheses claim the same qualitative mechanism - properly balanced excitation and inhibition. Thus, a natural question arises: how are the chaotic balanced state and criticality related, how do they differ? Here we propose an answer to this question based on investigation of a simple, network-level computational model. We show that the strength of inhibitory synapses relative to excitatory synapses can be tuned from weak to strong to generate a family of models that spans a continuum from ‘criticality’ to the ‘chaotic balanced state’. Our results bridge two long-standing competing hypotheses and offer a possible explanation of discrepant experimental observations: neuromodulatory mechanisms that tune the strength of excitatory and inhibitory synapses may tune cortical state from criticality to the balanced state, and to intermediate states between these extremes. Author summary What is the dynamical state of cerebral cortex? Are neurons mostly uncorrelated, firing asynchronously with each other? Are synchronous oscillations important? The answers to these questions have fundamental implications for how the cortical neural population encodes and processes information. Here we show that two possible scenarios - criticality and the chaotic balanced state - that are typically considered incompatible can be attained in the same network by maintaining a certain kind of balance, while tuning the strength of inhibition relative to excitation.
Development of Interactive Video Based Powerpoint Media In Mathematics Learning

This study aims to determine the effectiveness and practicality of interactive video-based PowerPoint media implemented in learning. This research and development phase refers to the Research and Development (RD (2). Practicality instruments in the form of questionnaires for teacher and student responses to interactive video-based PowerPoint media; and (3) Effectiveness instruments in the form of observations of learning outcomes and student learning outcomes. Based on data analysis, obtained an average level of media validity of 3.99 and included in the valid criteria. Also, the practicality test results are seen from the teacher's response to learning by 4.4 and the response of students by 3.46 with practical criteria. This is supported by the results of students' learning tests on the use of interactive video-based PowerPoint media with an average score of students learning outcomes of 70.29. Therefore, it can be concluded that the interactive video-based PowerPoint media developed is effective and practical in the implementation of learning. On the other hand, the development of this media focuses on the concept of integrated learning video learning using PowerPoint and concentrates on interactive learning.
Life cycle and eco-friendly management of Chinese fruit fly (Bactrocera minax) in sweet orange (Citrus sinesis Osbeck) in Nepal

Sweet orange (Citrus sinensis Osbeck) is a highly profitable fruit crop of Nepal. However, for the past five years, farmers experienced poor productivity partly attributed to the severe infestation of exotic Chinese fruit fly (Bactorcera minax), particularly in Sindhuli and Ramechhap district of Nepal. In this context, we attempted to review on identification, life cycle, and eco-friendly management of Chinese fruit fly. The review is documented based on a field visit and relevant works of literature from Journal articles, books, pamphlets, etc. The Chinese fruit fly has tremendous ability to take a long-range flight, thus, migrated from China to Bhutan and crossing the Indo-Nepal eastern border, finally reached to eastern mid-hills of Nepal. Moderate temperature and low humidity of mid-hills of Nepal are favorable for the exponential growth of the pest. Being sweet orange most preferable commodity, the host range of the fly includes almost all the citrus fruits. The fly has damaged 20-50% of the fruit every year and resulted in a loss of millions of rupees. Therefore various pest management practices can be deployed for sustainable eco-friendly management of the pest. The Chinese fruit fly can be successfully managed by hydrolase protein baits, regular pruning, augmentation of bio-control agents, and using soft systemic insecticides. Various other options for the management of Chinese fruit fly are also discussed with their biological efficacy for the sustainable and eco-friendly management of pests.
IN SILICO AND EXPERIMENTAL STUDIES FOR THE DEVELOPMENT OF NOVEL OXAZOL-5(4H)-ONES WITH PHARMACOLOGICAL POTENTIAL

New 2-(4-(4-X-phenylsulfonyl)phenyl)-4-(3-bromo/3-bromo-4-methoxy-benzylidene)oxazol-5(4H)-ones have been synthesized by reaction of some 2-(4-(4-X-phenylsulfonyl)benzamido)acetic acids derivatives with 3-bromobenzaldehyde or 3-bromo-4methoxybenzaldehyde. The structures of the newly obtained heterocycles were elucidated by IR, H-NMR, C-NMR, mass spectra and elemental analysis. The cytotoxicity of the new oxazolones was evaluated using Artemia salina and Daphnia magna organisms and the in vitro antimicrobial activity was assessed on Gram-positive and Gram-negative bacterial and fungal strains.
Temperature and magnetic field dependent behavior of atomic-scale skyrmions in Pd/Fe/Ir(111) nanoislands

The thermal stability of atomic-scale skyrmions is of high relevance for potential spintronics applications and validation of theoretical models. We investigated Pd/Fe nanoislands on an Ir(111) substrate as a function of temperature and magnetic field. Utilizing noncollinear magnetoresistance contrast in scanning tunneling microscopy, the thermomagnetic phase space is explored up to 3 T within a temperature range between 1 K to 100 K. Evidence is found for the spin spiral, field-polarized, and fluctuating disordered magnetic phases. Evidence for the presence of atomic-scale skyrmions at up to approximately 80 K is found, irrespective of considerable magnetization dynamics arising from thermal agitation.
A Reconstruction of pelvic ring after Hemipelvectomy and Fibular graft at 39 – years – old man with Aneurysmal Bone Cyst at Iliac bone

Introduction: The ABC (Aneurysmal Bone Cysts) lesion has been reported in the orthopedic literature for more than 60 years; it was first described in 1942 by Jaffe and Lichtenstein. Aneurysmal bone cyst (ABC) in pelvic is a benign, expansile osteolytic lesion that typically affects the metaphysis of long bones in the second decade of life and occurring in patients less than 20 years. The Several ABC treatment modalities had been utilized including wide resection, intralesional resection/curettage with or without different adjuvants, radiation, embolization, intralesional sclerotherapy. Case Report: We present a rare case of a huge aneurysmal bone cyst (ABC) in the iliac bone, occurring in the male patient 4th decade of life. The patient presented with a history of pain and huge pelvic mass size 8x6x5 cm extend to abdominal region for 5 years. Plain radiograph and computed tomography showed expansile lytic lesion arising from the all right iliac bone extend to Lumbar 5. A biopsy was performed and histology confirmed diagnosis of aneurysmal bone cyst. The patient was managed surgically with hemipelvectomy type 1 and Autogenous bone graft from fibula and reconstruction with plate and screw for pelvic ring with and reattach the muscle on it. Follow up 5 months after surgery the patient can squat and stand maximally with no pain, nor recurrence and can return to normal activity.
Meaning in Life Questionnaire: Factor Structure and Gender Invariance in a Romanian Undergraduates Sample

The purpose of the present study is to analyze the psychometric properties of the Meaning in Life Questionnaire (MLQ) (one of the most widely used instruments for the assessment of the meaning in life) for a sample of 320 undergraduate students (149 males and 171 females; Mage = 19.29; S.D. = 1.42). The MLQ is built around two scales: the MLQ-P (5 items), which measures the Presence of Meaning, and the MLQ-S (5 items), which is focused on the Search for Meaning. The psychometric analysis carried out by means of the exploratory factor analysis (EFA) and the confirmatory factor analysis (CFA) confirmed that the MLQ has a two-factor structure according to the original version and adequate fit coefficients (χ² / df = 2.67; CFI = 0.957; RMSEA = 0.073; SRMR = 0.0711). The internal consistency is acceptable: Cronbach’sα = 0.79, for the MLQ-P and α = 0.85 for the MLQ-S. As for the measurement of the gender invariance, achieved through multigroup-CFA, the results have shown that there is strong invariance. The relations of the MLQ with the instruments for well-being (MHC-SF), flourishing (FS), and the positive and the negative affect (SPANE) suggestthe existence of adequate convergent validity.
Dual-Sense Circularly Polarized Antenna With a Dual-Coupled Line

This letter presents a dual-sense circularly polarized (CP) microstrip patch antenna with a dual-coupled line. The rectangular patch antenna operating in TM01 mode is utilized as a basic design, and a single-coupled line is introduced to excite the TM10 mode with a phase difference of 90°, generating CP operation. As different polarizations can be obtained by changing the position of the single-coupled line, a dual-coupled line is introduced to the rectangular patch antenna to excite two CP modes with different polarizations. The prototype of the dual-band dual-sense CP antenna is fabricated and measured. The measured results illustrate that the dual-sense CP antenna obtains a wide impedance bandwidth of 7.95% and dual axial ratio (AR) bandwidth of 0.33% for the left-hand circular polarization (LHCP) and 0.72% for the right-hand circular polarization (RHCP). Furthermore, the antenna has a wide 3 dB axial-ratio beamwidth and a small frequency ratio of 1.04.
Mechanical properties of concrete subjected to cyclic thermal loading

Abstract This paper studies the effect of thermal cyclic loading on the mechanical properties of concrete such as cylinder and cube compressive strength, splitting and flexural tensile strengths, and weight loss. The specimens were exposed to 7–28 thermal cycles with peak temperatures of 100, 200 and 300 °C. A total of 120 specimens consisting of cubes, cylinders and prisms were tested in this study. The compressive strength of concrete enhances up to 7 or 14 thermal cycles and subsequently decreases but remains greater than the strength at ambient temperature at all temperature levels. The test results highlight the difference in compression behaviour of concrete cylinders and cubes. The effect of thermal cycles on splitting tensile strength of concrete is more pronounced than its effect on the modulus of rupture. Although the splitting tensile of concrete decreases with rise in the peak temperature and number of thermal cycles, the modulus of rupture increases up to seven cycles for exposure to the temperature cycles of 100 and 200 °C, which is even higher than the control. Models are developed to predict residual mechanical properties of concrete after exposure to the thermal cycles, which show close conformance with experiments.
Haematology, bronchoalveolar cellular changes and pathology of swine pneumonia in Nigeria

Respiratory diseases are of considerable economic importance in pigs, and less emphasis is on the diagnostic approaches in porcine health in our environment. The aim of this study was to compare the diagnostic accuracy of haematology, gross, bronchoalveolar lavage (BAL) and histopathological changes of pneumonia in pigs. The study was conducted at a municipal abattoir for over three months. 146 finished pigs were clinically examined. Blood samples were taken, while the plucks were examined for lung lesions. Lavage samples and lung sections were taken for BAL and histological examinations. Six breeds were slaughtered comprising Large White 112 (77%), Mixed Breed 15 (10%), Duroc 7 (5%), Local 6 (4%), Hampshire 4 (3%), and Large Black 2 (1%). 71 (49%) were males and 75 (51%) were females. Grossly, there was pneumonia in 92 (63%) of the pigs and the mean pulmonary consolidation score was 9.6±1.2. The large white breed had the highest consolidation score. Also, the right and left caudal lobes had the highest consolidation scores. Clinically, there was mild anaemia and leukocytosis, and BAL fluid cellular differential showed increased lymphocytic and neutrophilic counts in the pigs with pneumonia (p
