A HIGH GAIN DOUBLE-OCTAGON FRACTAL MICROSTRIP YAGI ANTENNA

A Double-Octagon Fractal Microstrip Yagi Antenna (D-OFMYA) which is aimed to cover unlicensed frequency of 5.8 GH is presented in this paper. The primary purpose of this experiment is to enhance gain of conventional microstrip antenna. The proposed antenna built on Arlon CuClad 217 substrate with thickness of 0.787 mm and dielectric permittivity of 2.2. A 3D full-wave EM simulator was used to design and to simulate the antenna. A computerized simulation model of the proposed antenna showed that the antenna is able to generate a maximum gain of 14.49 dB with S11 of −24.2 dB in a surface size of 80mm × 120 mm. By contrast, results of an experiment indicated the fabricated D-OFMYA can reach a gain as high as 14 dB with the value of S11 is −19.8 dB. It can be concluded that a nominal gain of the D-OFMYA comes in higher than other microstrip Yagi array antennas and size reduction can be achieved through this design.
The evaluation of green manufacturing strategies adopted by ISO 14001 certificate holders in Jordan

The aim of this study is evaluating the performance of green manufacturing strategies adopted by ISO 14001 certificate holders in Jordan. The survey questionnaire was developed based on the literature and interviews with industry experts and academics, 27 manufacturing organisations were surveyed. K-mean clustering analysis was used to cluster the manufacturing organisations to green manufacturing strategic groups. Also, perfect matching analysis was used to trace the relationship between performance indicators and green actions. This study revealed that; there are three significant clusters of green manufacturing strategies: agile environment, care-taker environment and lean environment. The performance of agile strategic group is high to moderate; however, the performance of care-taker and lean is moderate to low. Different combinations of perfect matched green actions with performance indicators were adopted by each strategic group. This is the first study which reports the green manufacturing strategic patterns in Middle East, the majority of previous studies have not addressed the significant actions and performance indicators in details, the majority of previous studies have not clustered or grouped the manufacturing firms based on green key performance indicators.
Job shop management of products under internal lifespan and external due date

Deteriorating items are found in a wide variety of productive environments and have been extensively reported in the literature. However, the evolution of markets demand the development of new products and new forms of work are made necessary to adapt production systems to those changes. The present work focuses on the production control of perishable products in a job shop environment. Specifically, in those products that have an expiration date within the production interval (internal caducity) that must be delivered before a certain date. As far as we know, there are no previous works that focus on the internal caducity of products at the production-control level. Two systems of different nature have been compared: Workload Control (WLC) and Kanban. WLC is usually a benchmark in job shop and made to order environments. Recent studies show that Kanban, traditionally used in JIT (Just in Time) environments, performs similarly or even better than WLC. The study was performed by discrete events simulation using Python© language, SimPy© and DEAP© modules, and considering several responses of the systems. The results show that both systems have a good performance in a variety of scenarios, with overall performance of Kanban in terms of internal caducity and tardy deliveries.
Causes of Engineering Change Propagation: An Analysis During Product Lifecycle

Abstract This article identifies the causes of engineering change propagation during the development and production phases of the product lifecycle using a statistical method applied to a large engineering change data set from the locomotive industry. This research identified three key influencing variables that were found to be related to engineering change propagation, namely: the engineering subsystem issuing the change, the subsystem interface complexity, and the designer experience. Predicting key influencing variables can reduce change propagation and provides important insights to practicing engineering managers. In particular, the results of this study can be used to improve engineering change decision-making processes and the utilization of resources. Similar complex systems composed of multiple subsystems can also benefit from the findings of this research.
Operational characterization of CSFH MEMS technology based hinges

Progress in MEMS technology continuously stimulates new developments in the mechanical structure of micro systems, such as, for example, the concept of so-called CSFH (conjugate surfaces flexural hinge), which makes it possible, simultaneously, to minimize the internal stresses and to increase motion range and robustness. Such a hinge may be actuated by means of a rotary comb-drive, provided that a proper set of simulations and tests are capable to assess its feasibility. In this paper, a CSFH has been analyzed with both theoretical and finite element (FEM) methods, in order to obtain the relation between voltage and generated torque. The FEM model considers also the fringe effect on the comb drive finger. Electromechanical couple–field analysis is performed by means of both direct and load transfer methods. Experimental tests have been also performed on a CSFH embedded in a MEMS prototype, which has been fabricated starting from a SOI wafer and using D–RIE (deep reactive ion etching). Results showed that CSFH performs better than linear flexure hinges in terms of larger rotations and less stress for given applied voltage.
Telework Uptake and COVID: Will it be Back to Normal? - A Preliminary International Comparison

To date research on telework has predominantly focused on aspects related to organisations and employees, however, research currently falls short of cross-cultural studies investigating how cultural differences may vary the adoption and use of telework. COVID-19 has demonstrated the demands for working from home and countries with different cultures have expanded telework use as part of the COVID ‘new normal’. We identify patterns on the uptake of telework through pre-and postCOVID-19 and apply Hofstede’s 6-Dimension model to investigate how cultural consequences may interact with the use of telework in the post-pandemic practice. We evaluate how cultural dimensions influence the acceptance of telework, thereon discuss our preliminary insights on future development needs for better cultural appropriate practices. Our study aims to provide a shared understanding for telework across cultures, shedding light on the potential for further in-depth explorative research on the use of information systems for telework in different cultural settings.
Aerodynamic damping in cables of overhead transmission lines subjected to wind loads

Traditionally, the analysis of cables under the influence of wind is performed using an equivalent static analysis. However, the occurrence of countless accidents in structural systems where cables are involved, even in cases where the project speed limit has not been reached, indicates that the collapse may have been caused by dynamic actions or by underestimated values of wind speed. The aim of this article is to introduce a dynamic analysis methodology for cables under the influence of wind and its forces. The validation procedure proposed is performed through a comparison among the results obtained, results from other researches, and wind tunnel experimental results. In parallel, comparison of the results is obtained in both static and dynamic analysis.

Review on Influencing Factors of Gender Identity Development of Adolescent Individuals

"Adolescence" has always been the focus of the whole society. With the development of adolescent socialization, the hidden dangers of adolescent gender role identity and mental health problems are becoming more and more prominent. With the continuous attention of academic circles to adolescent education, family education and school education, as one of the important forms of adolescent education, have an important impact on promoting adolescent individuals' cognition of gender roles and the development of mental health. Through reviewing the previous relevant theories and literature, this paper focused on the internal and external factors that influencing the development of gender cognition of adolescent individuals. External factors include the influence from the family and school education. The internal factors include the physiological factors which are mainly related with hormone as it emerges the body to form the characteristic of a gender, and the body factors about health. This paper found that parental rearing patterns had significant effects on gender role cognition and mental health of adolescent individuals. Meanwhile, the development of school education is inseparable from the active cooperation of family education. The realization of family education also needs the support of school education.
Making sense of team integration practice through the “lived experience” of alliance project teams

Purpose Team integration is a concept that has been widely fostered in alliances as a way of improving collaborative relationships between diverse organisations. However, deeper insights into the practice of high levels of team integration remain elusive. The purpose of this paper is to develop a deeper understanding of team integration through the “lived experience” of practitioners in an alliance. Design/methodology/approach This study employed a qualitative research methodology. Using a phenomenological examination, via the lived experiences of 24 alliance practitioners, the practice of alliance team integration has been investigated based on the key indicators that foster alliance team integration: team leadership, trust and respect, single team focus on project objectives and key results areas, collective understanding, commitment from project alliance board, single and co-located alliance team, and free flow communication. Findings The findings highlight that alliancing gives the project teams’ flexibility to change and adapt, to advance the collaborative environment and that successful integration of multi-disciplinary project teams requires commitment to the identified indicators. These findings have led to the development of a framework of leadership for successful alliance integrated practices. It is proposed that to influence the leadership for the purpose of achieving successful integration practice, a team-centric approach is required which includes four elements: task and relationship-oriented behaviours; collaborative learning environments; cultivating cross-boundary networks; and collaborative governance. Practical implications As team integration is the central tenet of alliance projects, greater understanding regarding the leadership of integration practice is of value in leveraging the benefits of outstanding performance. Also, the results of the study are expected to be informative and provide insight for alliance teams to help them proactively recognise how the context of integrated teams is influenced by specific indicators, impacting on the extent of integration practice. Originality/value This study contributes to the current body of knowledge concerning the insights from the “lived experience” of alliance teams towards achieving a greater understanding of what contributes to the leadership of successful integration practices.
T H E CATABOLISM OF HOMOLOGOUS AND HETEROLOGOUS 7S GAMMA GLOBULIN FRAGMENTS* BY HANS

Digestion of 7S antibodies with papain and pepsin results in the formation of fragments which retain biological activity. I t has been demonstrated by Porter that papain in the presence of cysteine splits the molecule into three fragments of about equal size with a sedimentation coefficient of 3.5S and a molecular weight of approximately 50,000 (1). Digestion of the 7S gamma globulin with pepsin has been shown by Nisonoff et al. to result in an active antibody fragment of a sedimentation coefficient of 5S and a molecular weight of 106,000 (2). The remaining part of the molecule is digested by pepsin into dialyzable polypeptides. In the last few years a number of investigators have been able to localize certain biological features of the 7S gamma globulin in these subunits obtained by enzymatic digestion. Papain fragments I and II, also called the S (slow) fragments because of their slow electrophoretie mobility, each carry an antibody combining site (1). The pepsin fragment is composed of two antibody-combining sites linked by a disulfide bond which can be easily reduced to form two smaller fragments closely resembling the papain fragments I and I I (2). The papain fragment III , or the F fragment (fast), does not interact with the antigen but is responsible for other biological functions of the antibody, such as complement fixation (3, 4), transmission to the fetal circulation (5), and fixation to the skin (6).
MOBILE DENTAL PHOTOGRAPHS: An Innovative alternative for shade determination

Aim: Esthetic dentistry involves shade determination. The conventional shade guide is a subjective method whereas spectrophotometer is an accurate but an expensive method. The need for determining the shade using an effective and inexpensive method is a clinical requirement. The study is aimed at comparing mobile dental photographs to spectrophotometer as an effective means of shade determination. Material and Method: 50 participants with no restorative or traumatic changes on the left central incisor were selected. Shade was determined using spectrophotometer and mobile photographs. The L*a*b* values obtained from each were noted. ΔE was determined and the agreement between the readings obtained by the two different methods was compared and subjected to appropriate statistical analysis. Results: The results showed that there was a statistically non-significant difference seen for the values between the 2 techniques (p>0.05). The mean ΔE was 1.5. There was a statistically significant difference between the proportion of ΔE more than and <2, between spectrophotometric and mobile dental photography methods (P < 0.01) with higher proportion of <2 ΔE. Conclusion: The mobile dental photograph is an effective reliable means of shade determination. It also can be used as an adjunct for shade communication and establishing the characterization for an esthetic restorations. Clinical significance: Mobile dental photographs has been established as one of the effective means of shade determination and communication without an additional expenditure. It can help mimic not only the shade but also the characterization by the lab personnel as the photograph communicates these details for reference.
Tolerance to ''Missing Self'' Cutting Edge: Viral Infection Breaks NK Cell

NK cells attack cells lacking MHC class I, yet MHC class I-deficient mice have normal numbers of NK cells with intact, albeit diminished, functions. Moreover, wild-type NK cells are tolerant of MHC class I-deficient cells in mixed bone marrow chimeras. In this study, we investigated how the absence of MHC class I affects NK cells. NK cells from (cid:1) 2 -microglobulin-deficient ( B2m (cid:2) / (cid:2) ) and wild-type mice exhibit similar phenotypic and functional characteristics. Both B2m (cid:2) / (cid:2) and wild-type Ly49H (cid:3) NK cells proliferated robustly and produced IFN- (cid:4) after infection with mouse CMV. NK cells in mixed wild-type: B2m (cid:2) / (cid:2) chimeric mice were initially tolerant of MHC class I-deficient host cells. However, this tolerance was gradually lost over time and after mouse CMV infection was rapidly broken, with a pronounced rejection of host B2m (cid:1) / (cid:1) hematopoietic cells. Thus, although NK cells can be held in check against “missing self,” acute inflamma-tion driven by infection can rapidly break established self-tolerance.

Supervised Machine Learning and Heuristic Algorithms for Outlier Detection in Irregular Spatiotemporal Datasets

A central problem in time series analysis is the detection of outliers, with further complications presented by irregular time series data measured having spatiotemporal components. This paper presents one Heuristic and two Supervised Machine Learning algorithms for the detection of outliers in this context in univariate time series data, with comparison of results to Chen and Liu's (1993) automatic outlier detection methodology. Due to the recent trend of set up of large environmental databases across many states in the US and around the world, which allow submission of pollutant measurement data from virtually any source, these procedures are applied to the measurements of various surface water pollutants in the California Environmental Data Exchange Network (CEDEN) for understanding and exploring the viability of such databases and the proposed methods. The proposed methodologies though not as robust, give similar results to existing methodologies given the nature of the data, but can be far less time intensive to implement providing interesting insights into the database. Thus, the algorithms presented can be widely used with minimal computing resource requirements with very tractable results even with very large datasets. The methodologies have wide applicability in a variety of contexts and a wide variety of databases with similar measurement challenges across many disciplines, specifically in the environmental setting. In particular, the results have large potential regulatory impact on accepted levels of different pollutants in California water bodies, as well as the amounts to be charged for industrial discharge into those water bodies, and is intended to provide direction for further research and regulatory investments. Based on the results it seems reasonable to assume that there is further room for the inclusion of nongovernmental agency pollutant measurements in the debate of environmental pollution, specifically in California. However, the results also indicate that the use of such databases in a more inclusive way for regulatory matters must be carefully evaluated on an individualized basis. That is to ensure that poorly collected/handled measurements, do not inundate the database over and above those collected with more rigor, thus potentially making inference on the true population distribution of the pollutants more difficult; being especially relevant for those pollutant measurements, which require more delicate sampling procedures.
Understanding CO2 reduction and efficiency in road freight transport and logistics. German surveys and case studies 2002-2005

Since 2002, numerous case studies have investigated the sustainability effects of efficiency measures in German road haulage companies. Particul ar focus was set on the impacts of the company measures “scheduling systems” and “introduc tion of on-board telematics” and on the sector analysis for the efficiency improvements i Courier, Express and Parcel (CEP) services. The purpose has been to arrive at further insights into the energy efficiency issues in those fields of business which have until now remai ned largely unexplored. One objective is to gain understanding of the mechanisms of various pro cesses, which influence efficiency and create new framework conditions; qualitative invest igations were carried out to this end. To tackle the lack of data, it is necessary to quantif y the current efficiency values at the company level, so that company decision making can be based on them. The aim is to discover whether the decoupling of freight traffic from energy consu mption is taking place at the business level and to investigate the potential for further steps in order to be able to make policy and company related recommendations. 1
Coagulation Cascade Model by Activating the Extrinsic Vitro in a Bronchopulmonary Dysplasia Endothelin-1 Signaling Promotes Fibrosis In

Neonatal respiratory distress syndrome can progress to bronchopulmonary dysplasia (BPD), a serious pulmonary ﬁbrotic disorder. Given the involvement of the extrinsic coagulation cascade in animal models of lung ﬁbrosis, we examined its role in BPD. We observed a higher number of neutrophils expressing tissue factor (TF) in bronchoalveolar lavage ﬂuid (BALF) from infants with BPD than from those with uncomplicated respiratory distress syndrome together with a parallel decrease in TF and connective tissue growth factor (CTGF) in BALF supernatants during the disease course. The involvement of coagulation in the ﬁbrotic process associated with BPD was further evaluated by treating primary human colonic myoﬁbroblasts with BALF supernatants from infants with BPD. These human colonic myoﬁbroblasts demonstrated an enhanced C5a- and thrombin-dependent migration. Moreover, they expressed TF in an endothelin-1–dependent manner, with subsequent activation of the extrinsic coagulation cascade and CTGF production mediated by protease-activator receptor-1 signaling. These data provide a novel mechanism for the development of BPD and indicate that endothelin-1 signaling contributes to ﬁbrosis by upregulating a TF/thrombin ampliﬁcation loop responsible for CTGF production, and offer novel and speciﬁc therapeutic targets for pulmonary ﬁbrotic disease.

Exemplars of Integration in Engineering Education’s Use of Mixed Methods Research

This theory paper explores ways in which the engineering education community can achieve more comprehensive integration in mixed methods designs. We searched for exemplars in the Journal of Engineering Education, the European Journal of Engineering Education, and the Australasian Journal of Engineering Education using “mixed-method” and “mixed methods” as keywords – resulting in 60 viable articles. Using Creamer’s Mixed Methods Evaluation Rubric (MMER), we found exemplar articles demonstrating considerable proficiency across one or more of the rubric’s four criteria: (1) amount of mixing, (2) interpretive comprehensiveness, (3) transparency and (4) methodological foundation. Using the exemplars as discussion points, we advocate for: (1) the use of mixing during analysis to increase the interplay between the different strands of inquiry (amount of mixing), (2) framing results using the study’s constructs, research questions, or perspectives to avoid siloing the study’s approaches (interpretive comprehensiveness), (3) using methods flowcharts to communicate design features (transparency), and (4) drawing from a more extensive body of methodological literature to justify design decisions (methodological foundation).
