The Right Time for Makerspaces in Nigerian Academic Libraries: Perceived Benefits and Challenges

The present study investigates makerspaces in Nigerian academic libraries: perceived benefits and challenges. Four objectives guided the study: what constituted makerspace in academic library, the level of awareness of makerspace by academic library benefits and challenges of adopting makerspace in libraries. The descriptive survey design was adopted and questionnaire was used for data collection. The population of the study comprised of professional and paraprofessional librarians of Ambrose University and University of Benin, from which a sample size of 119 was drawn using total enumeration sampling technique. Out of the 119 copies of questionnaire administered, 94 were retrieved and analyzed using simple percentage and frequency tables. Findings revealed that, the respondents were aware of what constitute makerspace which are library space, 3D printers, computers and projector. It was also discovered that, the respondents had a high level of awareness of makerspace in the library. Some of the benefits associated with the use of makerspace are: it facilitates group interaction, it improves knowledge and provides access to wide varieties of tools and technology. Some of the challenges encountered in the adoption of makerspace are training of academic library staff, security of makerspace gadgets, poor funding, erratic power supply, high cost and maintenance of equipment. It was however recommended that; librarians should make deliberate effort to explore the potentials in makerspace in the enhancement of their services and training should be conducted regularly to enhance librarian’s skills in the use of ICTs.
New Methodology for Efficient Process Parameters Optimization in Selective Laser Melting A Novel Algorithmic Approach for SLM Process Optimization Based on Optical Metrology

INTRODUCTION: Selective laser melting (SLM) is a powder bed additive manufacturing technology that enables the production layer-by-layer of complex metal components with high mechanical performance. In recent years, this technique is starting to be adopted for production of end-use parts, addressing high quality requirements. Optimization of process parameters is one of the ways to achieve desired quality of a final product. However, the currently available process optimization methodologies take long time and there is a lack of standards.
The application of 3D metrology software in the quantitative and qualitative assessment of aligner treatment outcomes

Abstract 3D metrology software (Geomagic® Control X™) can be used in orthodontic treatment to significantly improve the analysis of achieved tooth movements compared with those predicted by treatment planning software, such as ClinCheck® software (Align Technology®). The applications of this technology enable clinicians to present more accurate and detailed case presentations and analyse their treatment outcomes. Additionally, information presented may further aid clinicians in interpreting and understanding metrology-derived information, in the form of digital heat maps, when incorporated into case presentations and scientific articles.
What makes a CSA a CSA: A framework for comparing community supported agriculture, with cases from Canada and China

In different parts of the world, community supported agriculture (CSA) has taken a variety of organizational forms, drawn on different ideologies, used a variety of land tenure arrangements, and taken on varied types of market relations in terms of how they arrange sales and memberships. Despite this, comparative studies of CSAs are sparse. Based on interviews and survey results, this paper develops a framework to compare CSAs in Canada—where this system has evolved for the last 30 years as an alternative to industrialized agriculture—with those in China, where CSAs have emerged since the late 2000s, mainly in response to food safety and health concerns. The comparison is based on their initiators’ motivations, economic characteristics, ecological practices, shareholder relations, and community building. We find that in both Canada and China CSAs are struggling to maintain the movement’s original values and be economically viable. They are moving away from the traditional ‘risk sharing’ approach underpinning the model and adopting more flexible payment mechanisms. However, other original tenets of the CSA model, such as member engagement, are strengthening. This poses a definitional challenge—what makes a CSA a CSA? We conclude that CSAs mix capitalist and other-than-capitalist economic logic, blend traditional, organic, and productivist ecological relations, and demonstrate both individualist and civic collectivist politics simultaneously. These characterizations are what make a CSA a CSA in contemporary Canada and China.
DOUBLE BOOST RESONANT CONVERTER

A new high efficiency resonant boost converter is introduced. Topology is a hybrid circuit between a switched resonator and a switched-capacitor converter. The voltage gain is adjustable and full range zero current switching operation is given for switches independent of operating voltages and load capacity. The structure is built without any additional switch in the circuit by an inverter arm. All high frequency resonant types are passive components, and then small size realization is possible. Stability of the converter is assured.
Micro-morphological and anatomical response of groundnut (Arachis hypogaea L.) cultivars to ground-level ozone

Tropospheric ozone is a phytotoxic gaseous pollutant with global warming potential that disrupts the plants growth and development directly or through climate change. Ozone enters into a plant’s body through stomatal pores and develops oxidative stress, which results in injury to foliage and modifies leaf micro-morphology and anatomy. A field study was conducted to assess the morphological, micro-morphological, and anatomical response of groundnut cultivars (Arachis hypogaea L.) to enhance the level of ozone. This study observed ozone-like visible injury symptoms on all groundnut cultivars. Visible injury was maximum in cultivar Dh-86 and minimum in cultivar TPG-41. Micro-morphological characteristics, such as increase in stomata, epidermal cells number, and its index, were also increased under enhanced ozone-exposed plants. The highest stomatal index was found in cultivar TPG-41 and lowest were noted in cultivar GG-20. Cultivars TAG-24 > TG-37A > and Dh-86 show moderate modification in the morphological and micro-morphological characteristics of plants. Elevated ozone also affected the stomatal movement and leaf internal tissue. Most of the stomata of all the groundnut cultivars were observed as closed during the enhanced ozone exposure, suggesting a protective mechanism from ozone stress. The study concluded that the micro-morphological and anatomical characteristics are important aspects to determine the effect of ozone on plants and to influence plants sensitivity to ozone. On the basis of these characteristics, cultivar TPG-41 was found to be less sensitivity, while cultivar Dh-86 was found to be highly sensitive to ozone pollution.
Sensitivity Analysis of the UTBSOI Transistor based Two-Stage Operational Amplifiers

In the nanoscale domain, the MOSFETs are prone to various physical effects due to their shorter channel region known as short-channel effects (SCE). The researchers have proposed an advanced structure of MOSFET known as the ultrathinbody silicon-on-insulator (UTBSOI) to overcome the limitations of SCEs. The UTBSOI is a type of double-gate (DG) MOSFET having superior controllability of gates over the shorter channel region. Nowadays, the UTBSOI MOSFETs can be adopted in the circuit simulators through the use of a device model named BSIM-IMG. The BSIM-IMG has made it possible for the circuit designers to simulate any UTBSOI based analog blocks like operational amplifiers (opamp). The performance parameters of an opamp are very much sensitive to any perturbation in size (W/L) of the constituent MOSFETs, that may cause a drastic change in the output. In this paper, the sensitivity analysis procedure has been proposed for the CMOS and UTBSOI based two-stage opamps as the function of perturbation in W/L. In addition to this, an algorithm has also been presented to do the same. From the simulation results, it is observed that the sensitivity of the UTBSOI based opamp (UTBSOI-opamp) is larger than that of CMOS based opamp (CMOS-opamp).
What can literacy and cognitive abilities of the brain tell us about critical thinking?

Mrs. Kolinsky traces a trajectory from the concept of literacy of the 19th century, going through evidence of changes in literacy in the cognitive capacities of literate subjects, until the data description from pretest sessions of her research with adults at EJA (Youth and Adult Education) in Belgium. Professor contributes with important thoughts on the acquisition of reading/writing and cognitive correlates and its impact on society. The researcher brings evidence of the relationship between literacy and critical thinking and the distortion of information. She highlights literacy to the formation of critical thinking by citizens, whose role is crucial to the democratic dynamics of a country. In Brazil, low literacy stands out negatively in the reading rates of young people assessed by Pisa, classifying more than 70% of them as bad readers, turning into a serious and alarming situation in the country.
ANOMALY DETECTION ON RUN TIME MACHINES USING OC-SVM

: Intrusion Detection Systems (IDSs) be worn to recognize and report unauthorized otherwise suspicious computer or network actions. Host-based IDSs, the thought of this paper, are planned to observe the host system deeds, while network-based IDSs check network traffic in favor of multiple hosts. Agreeing to their detection techniques, IDSs can also be off the record into misuse detection or anomaly detection conditional to whether the intrusion patterns are recognized or not through the design phase [10].
Evaluation and Comparison the Antibacterial Activity of Silver Nano Particles (AgNPs) and Silver Nitrate (AgNO3) on Some Pathogenic Bacteria

Resistance of bacteria to some antibiotics increased tremendously therefore demanding for solutions and new medicine becomes essential as this problem related to human health. For this purpose, using of nanoparticles increased rapidly during the last years. In this study, the effect of silver nanoparticles (AgNPs) and silver nitrate (AgNO 3 ) on bacteria had been evaluated and compared. Commercial purchased silver nanoparticles (with the particles size 20nm and Scanning Electron Microscopy (SEM) image) were characterized by X-ray diffraction (XRD). Antimicrobial activity of nanoparticles Silver and silver nitrate were evaluated on some pathogenic bacteria including samples including: Streptococcus pyogenes and Staphylococcus aureus (Gram Positive Bacteria)and Escherichia coli , Klebsiella pneumonia, Salmonella typhi, Acine to bacter baumannii and Vibrio cholerae (Gram Negative Bacteria). In this research, antibacterial activity for nanoparticle silver and silver nitrate at different concentrations started from 10 to 150μg ml − 1against bacterial isolates was measured by agar diffusion technique and Minimum Inhibitory Concentration (MIC)/ Minimum bactericidal Concentration (MBC). These pathogens caused different hazardous infections and some of these bacteria are multi-drug resistant, the results exhibited remarkable antibacterial activity of silver nanoparticles (AgNPs) compared to moderate effect of silver nitrate (AgNo 3 ) against most tested isolates including serious Gram Negative Bacteria resistant bacteria K.pneumonia , S. typhi and V. cholerae , the exception was A. baumannii as these bacteria didn’t affected definitely by any concentrations of Ag NP s or AgNo 3 in the detection tests of MIC and MBC.

Silicon-Based Biomaterials Modulate the Adaptive Immune Response of T Lymphocytes to Promote Osteogenesis/Angiogenesis Via Epigenetic Regulation

Silicon (Si)-based biomaterials have been widely applied for bone regeneration. However, the underlying mechanisms remain unknown. T lymphocyte-mediated adaptive immune response plays a vital role in the process of bone regeneration. In the present study, mesoporous silica (MS) was used as a model material of Si-based biomaterials. It showed that the supernatant of CD4 + T cells pretreated with MS extract significantly promoted the vascularized bone regeneration. The potential mechanism is closely related to the fact that MS extract could reduce the expression of regulatory factor X-1 (RFX-1) in CD4 + T cells, which could lead to interleukin-17A (IL-17A) overexpression through increased histone H3 acetylation and decreased DNA methylation and H3K9 trimethylation. Importantly, the in vivo experiments further revealed that MS particles dramatically stimulated bone regeneration with improved angiogenesis in the critical-sized calvarial defect mouse model accompanied by upregulation of IL-17A in peripheral blood and the proportion of Th17 cells.
Testing for goodness rather than lack of fit of continuous probability distributions

The vast majority of testing procedures presented in the literature as goodness-of-fit tests fail to accomplish what the term is promising. Actually, a significant result of such a test indicates that the true distribution underlying the data differs substantially from the assumed model, whereas the true objective is usually to establish that the model fits the data sufficiently well. Meeting that objective requires to carry out a testing procedure for a problem in which the statement that the deviations between model and true distribution are small, plays the role of the alternative hypothesis. Testing procedures of this kind, for which the term tests for equivalence has been coined in statistical usage, are available for establishing goodness-of-fit of discrete distributions. We show how this methodology can be extended to settings where interest is in establishing goodness-of-fit of distributions of the continuous type.
Complications and Risk Factors of Patients Undergoing Computed Tomography-Guided Core Needle Lung Biopsy: A Single-Center Experience

Objectives To determine the risk factors and complications of transthoracic computed tomography (CT)-guided core needle lung biopsy. Methods This is a retrospective study of 124 patients who underwent CT-guided core lung biopsy in King Khalid University Hospital (KKUH), Riyadh. This retrospective study was conducted between January 2016 and January 2020. Patient data were collected using a standardized data form that was entered into an Excel sheet in accordance with the variables. The Statistical Package for the Social Sciences software (SPSS, version 24.0 [SPSS Inc., Chicago, IL, USA]) was used to compute for the risk of complications after CT-guided core lung biopsy and perform all statistical comparisons, and the results were reported. Results The overall complication rate due to CT-guided core needle biopsy was 34.7% (43) (P<0.001) of the total sample. Of the total complications, 69.76% (n = 30) had pneumothorax, 20.94% (n = 9) had hemorrhage, 6.98% (n = 3) had both pneumothorax and hemorrhage, and 2.32% (n = 1) had both air embolism and pneumothorax. Of all patients who developed pneumothorax, 20% (n = 6) required chest tube insertion. Patients with secondary chronic obstructive pulmonary disease (COPD) had a complication rate of 80% among the whole sample. Lung lesions less than 3 cm had a complication rate of 48.8% (P<0.034). The needle size showed a higher rate of complications between 20 and 18 gauge with 47.4% (n = 9) and 32.4% (n = 34), respectively. Conclusions We conclude that CT-guided lung biopsy is a well-established low-risk procedure that is less invasive. However, it still carries a risk of complications with some risk factors, such as small lung lesion size and secondary COPD.
Uterine Notch2 facilitates pregnancy recognition and corpus luteum maintenance via upregulating decidual Prl8a2

The maternal recognition of pregnancy is a necessary prerequisite for gestation maintenance through prolonging the corpus luteum lifespan and ensuring progesterone production. In addition to pituitary prolactin and placental lactogens, decidual derived prolactin family members have been presumed to possess luteotropic effect. However, there was a lack of convincing evidence to support this hypothesis. Here, we unveiled an essential role of uterine Notch2 in pregnancy recognition and corpus luteum maintenance. Uterine-specific deletion of Notch2 did not affect female fertility. Nevertheless, the expression of decidual Prl8a2, a member of the prolactin family, was downregulated due to Notch2 ablation. Subsequently, we interrupted pituitary prolactin function to determine the luteotropic role of the decidua by employing the lipopolysaccharide-induced prolactin resistance model, or blocking the prolactin signaling by prolactin receptor-Fc fusion protein, or repressing pituitary prolactin release by dopamine receptor agonist bromocriptine, and found that Notch2-deficient females were more sensitive to these stresses and ended up in pregnancy loss resulting from abnormal corpus luteum function and insufficient serum progesterone level. Overexpression of Prl8a2 in Notch2 knockout mice rescued lipopolysaccharide-induced abortion, highlighting its luteotropic function. Further investigation adopting Rbpj knockout and DNMAML overexpression mouse models along with chromatin immunoprecipitation assay and luciferase analysis confirmed that Prl8a2 was regulated by the canonical Notch signaling. Collectively, our findings demonstrated that decidual prolactin members, under the control of uterine Notch signaling, assisted pituitary prolactin to sustain corpus luteum function and serum progesterone level during post-implantation phase, which was conducive to pregnancy recognition and maintenance.
Is Calorie Labeling on Menus Related to Weight Disturbances among Females in Saudi Arabia?

Calorie labeling is a recent initiative from the Saudi Food and Drug Authority (SFDA) aimed to reduce the prevalence of noncommunicable diseases (NCDs) by influencing people to make healthier food choices when they eat out and can also help people with weight disturbances to be more aware of their calorie intake. The present study aimed to investigate the association between the use of calorie labeling on restaurant menus, calorie intake, weight concern, body weight perception, and weight-control behaviors among young women. A quasi-experimental study was conducted among female students at a university restaurant. Participants were assigned to two groups: food menus with (experimental group) and without (control group) calorie labeling. The logistic regression model assessed the predictors of using calorie information separately for the experimental and control groups. Calorie labeling had a significant effect on reducing calorie consumption in the experimental group by 59 calories compared to the control group. The higher weight concern in the control group (OR = 0.410; 95% CI 0.230–0.730; P ≤ 0.002) was a predictor for using calorie information. The experimental group had higher weight concern (OR = 1.530; 95% CI 1.107–2.115; P ≤ 0.01) and body weight perception (OR = 4.230; 95% CI 1.084–6.517; P ≤ 0.038) and lower calorie intake (OR = 1.005; 95% CI 1.001–6.517; P ≤ 0.008) predictors for using calorie information. Weight-control behaviors did not significantly predict the use of calorie information in the groups. Calorie labeling might increase the weight disturbances among young females. More investigation is needed across various populations to gain a better understanding of calorie labeling as an effective food choice among people who are vulnerable to weight disturbances or already have weight disorders.
Bardoxolone-Methyl Prevents Oxidative Stress-Mediated Apoptosis and Extracellular Matrix Degradation in vitro and Alleviates Osteoarthritis in vivo

Purpose Oxidative stress-induced chondrocyte apoptosis and extracellular matrix (ECM) degradation plays an important role in the progression of osteoarthritis (OA). Bardoxolone methyl (BM), a semisynthetic triterpenoid, exerts strong effect against oxidative stress. The purpose of the present study was to determine the effectiveness of bardoxolone-methyl (BM) in preventing oxidative stress-induced chondrocyte apoptosis and extracellular ECM degradation in vitro and the role of alleviating OA progression in vivo. Methods Oxidative damage was induced by 25 mM tert-butyl hydroperoxide (TBHP) for 24 h in rat chondrocytes. 0.025 and 0.05 µM bardoxolone-methyl (BM) were used in vitro treatment. Ex-vivo cartilage explant model was established to evaluate the effect of BM on oxidative stress-induced ECM degradation. The mouse OA model was induced by surgical destabilization of the medial meniscus. Results In vitro, 0.025 and 0.05 µM BM reduced TBHP-induced excessive ROS generation, improved cell viability, increased malondialdehyde level and decreased superoxide dismutase level. 0.025 and 0.05 µM BM prevented TBHP-induced mitochondrial damage and apoptosis in chondrocytes BM activated heme oxygenase-1 (HO-1)/NADPH quinone oxidoreductase 1 (NOQ1) signaling pathway through targeting nuclear factor erythroid derived-2-related factor 2 (Nrf2). Additionally, BM treatment enhanced the expression levels of aggrecan and collagen II and inhibited the expression levels of matrix metalloproteinase 9 (MMP 9), MMP 13, Bax and cleaved-caspase-3. BM increased proteoglycan staining area and IOD value in ex vivo cultured experiment cartilage explants and improved the OARSI score, stands, max contact mean intensity, print area and duty cycle in mouse OA model. Conclusion BM prevented oxidative stress-induced chondrocyte apoptosis and ECM degradation in vitro and alleviated OA in vivo, suggesting that BM serves as an effective drug for treatment with OA.
Improving health care from the bottom up: Factors for the successful implementation of kaizen in acute care hospitals

Background Kaizen—a management technique increasingly employed in health care—enables employees, regardless of their hierarchy level, to contribute to the improvement of their organization. The approach puts special emphasis on frontline employees because it represents one of their main opportunities to participate directly in decision making. In this study, we aimed to (1) understand the experiences of nurses in two hospitals that had recently implemented kaizen, and (2) identify factors affecting the implementation of the technique. Methods By means of purposeful sampling, we selected 30 nurses from different units in two private acute care hospitals in Switzerland in May 2018. We used the Organizational Transformation Model to conduct semi-structured interviews and perform qualitative content analysis. Lastly, originating from Herzberg’s motivation theory, we suggest two types of factor influencing the implementation of kaizen—hygiene factors that may prevent nurses from getting demotivated, and motivational factors that may boost their motivation. Results Nurses generally experienced kaizen as a positive practice that enabled them to discuss work-related activities in a more comprehensive manner. In some cases, however, a lack of visible improvement in the workplace lowered nurses’ motivation to make suggestions. Nurses’ attitudes towards kaizen differed across both hospitals depending on the available managerial support, resources such as infrastructure and staffing levels. Conclusions From our findings, we derived several coping strategies to help health practitioners implement kaizen for the benefit of their organization and employees: Strong managerial support, appropriate use of kaizen tools, and a greater sense of team cohesion, among other factors, can influence how effectively hospital teams implement kaizen. To reap the benefits of kaizen, hospital managers should promote the exchange of opinions across hierarchy levels, allocate the necessary resources in terms of personnel and infrastructure, and show nurses how the technique can help them improve their workplace.
