Published: January 2020

People counting applications have been used in diverse applications. The ability and accuracy of thermal imaging over conventional image cameras has led to the implementation of thermal cameras in people counting applications. This paper present a thermal people counting smart glass windows. The people counting application would be remotely monitored from a single centralized PC station as it’s connected to a multiplex of mass monitoring of 20 thermal camera, all embedded into different glass windows. The thermal cameras would then be able to detect body temperatures of all individuals who pass through any of the camera range and also count the numbers of people who passed through the camera range. The data gotten can then be further utilized in various ways, example is in the control of air conditioning and lightening.

Published: January 2020

Aero-fuel centrifugal pumps are important power plants in aero-engines. Unlike most of the existing centrifugal pumps, a combination impeller is integrated with the pump to improve its performance. First, the critical geometrical parameters of combination impeller and volute are given. Then, the effects of combination impeller on flow characteristics inside the impeller and volute are clarified by comparing simulation results with that of the conventional impeller, where the effectiveness of selected numerical method is validated by an acceptable agreement between simulation and experiment. Finally, the experiment is performed to test the external performance of studied pump. A significant feature of this study is that the flow characteristics are significantly ameliorated by reducing the flow losses emerged in impeller inlet, impeller outlet and volute tongue. Correspondingly, the head and efficiency of combination impeller are higher with comparison to conventional impeller. Consequently, it is a promising approach in ameliorating flow field and improving external performance by applying a combination impeller to an aero-fuel centrifugal pump.

Published: January 2020

The city-port involves a decisive reality for the economic development of the territories and nations, capable of significantly influencing the conditions of well-being and quality of life, and of making the Circular City Model operational, preserving and enhancing seas and marine resources in a sustainable way, through the construction of appropriate production and consumption models, with attention to relations with the urban and territorial system. The Circular Economy paradigm identifies the ideal context in the city-port to rethink traditional development models and make ports driver areas for the regeneration of the city and metropolitan territories, in compliance with the EU Directive 2014/89 which considers maritime spatial planning as a tool for public authorities and stakeholders to achieve an integrated approach, promoting the development of maritime and coastal economies and the sustainable use of resources. The paper, starting from these assumptions, presents an adaptive decision-making process for the strategies development of the Naples (Italy) commercial port, aimed at re-establishing a sustainable city-port relationship and making operative Circular Economy principles.
An Intuitive and Realistic Visualization Method for Seabed Terrain
Authors: Xiao Zixian , Tan Liheng , Liu Hongli , Jiang Bingchuan , You Xiong
Published: January 2020

Visualization of the seabed terrain is one of the key functions of marine geographic information system. The major challenge here is that the obtained data for seabed terrain usually consists of elevation and sediment only but does not include remote sensing images, which is important for ground terrain visualization, as they can be used as textures to reveal detailed information and achieve realistic visual results. Existing seabed terrain visualizing methods (including annotations, color-mapping, and texture-mapping) have limitations in reality and intuition, as they are inadequate to express the physical characteristics of sediment accurately. This paper presents a novel and advanced 3D visualization method of seabed terrain, which introduces the Physically Based Rendering (PBR) theory into the field of geographic visualization. We analyze the main categories of seabed sediments and their optical features respectively, then develop a procedural method to generate physically based rendering materials for different sediments. Then an enhanced bidirectional reflectance distribution function is employed to achieve accurate and intuitive terrain rendering. We also refine the texture sampling method and propose a procedural seabed objects generation method to construct a more natural and realistic undersea environment. Experimental results reveal our method can make good use of the limited seabed terrain data and get significant improvements in visual effect, which can help users to cognize and analyze the seabed geographic environment more accurately and intuitively.

KAPASITAS SAMBUNGAN BALOK-KOLOM LAMINATED VENEER LUMBER (LVL) KAYU SENGON
Authors: Basuki Achmad , Supriyadi Agus , Muttaqin Muhammad
Published: January 2020

Keberadaan kayu belakangan ini semakin langka dan harganya semakin melambung tinggi. Salah satu alternatif untuk mengatasi masalah tersebut adalah menggunakan produk kayu rekayasa Laminated Veneer Lumber (LVL). Penelitian ini bertujuan untuk mengetahui kapasitas sambungan balok-kolom LVL dengan metode eksperimental. Sambungan ditentukan dengan bentuk kolom persegi dan balok berbentuk III dengan alat sambung baut yang diharapkan menjadi sambungan kaku (rigid connection). Pengujian dilakukan dengan penambahan beban pada ujung sambungan untuk mengetahui lendutan yang terjadi pada ujung balok. Dari hasil pengujian didapat kapasitas sambungan balok kolom LVL kayu sengon berturut-turut adalah 18,9; 19,9; dan 17,9 N/mm2. Perbandingan nilai pengujian dan analisis cukup jauh disebabkan karena sambungan yang diharapkan menjadi sambungan kaku tidak berhasil. Selisih perbandingan ini disebabkan karena pembuatan lubang baut yang tidak presisi, sehingga perlu dibuat sampel yang lebih bagus lagi agar bisa didapatkan sambungan kaku sesuai yang diharapkan.

Published: January 2020

Daerah Aliran Sungai (DAS) Tirtomoyo merupakan daerah yang memiliki tanah berjenis kapur yang rentan terhadap bencana kekeringan ketika musim kemarau. Untuk mengurangi dampak kekeringan, maka perlu mengenali karakteristiknya lebih awal. Penelitian ini bertujuan untuk menganalisis kekeringan hidrologi dengan menghitung indeks kekeringan dan debit bulanan yang kemudian dihubungkan untuk mendapatkan prediksi kekeringan. Indeks kekeringan digunakan untuk pemetaan kriteria kekeringan.

Penelitian kekeringan ini dilakukan pada tahun 2008-2017. Indeks kekeringan dianalisis dengan Metode Standardized Precipitation Index (SPI). Metode SPI merupakan metode indeks yang digunakan untuk menentukan penyimpangan tinggi hujan terhadap kondisi normalnya dalam satu periode yang panjang. Sedangkan debit bulanan dianalisis dengan Metode Global Rainfall-Runoff Model (GR2M). Nilai indeks kekeringan dan debit bulanan dihubungkan kedalam sebuah grafik. Grafik hubungan ini bertujuan untuk menghitung debit bulanan dengan berdasarkan nilai indeks yang didapatkan. Selain itu, klasifikasi dari indeks kekeringan SPI digunakan untuk pemetaan persebaran kriteria kekeringan dengan menggunakan software ArcGIS.

Hasil analisis diperoleh nilai indeks kekeringan SPI terkecil yaitu -1,71 dengan kriteria sangat kering pada Agustus 2016 dan indeks terbesar yaitu 2,19 dengan kriteria amat sangat basah pada Desember 2014. Sedangkan debit bulanan GR2M terkecil diperoleh 0,002 m3/detik pada November 2008 dan debit bulanan terbesar 0,426 m3/detik pada Februari 2009. Dari grafik hubungan indeks kekeringan SPI dengan debit bulanan diperoleh grafik linier dengan persamaan  , dengan  adalah debit bulanan GR2M dan  adalah indeks kekeringan SPI. Kemudian untuk pemeteaan persebaran kriteria kekeringan diperoleh bahwa kekeringan tidak terjadi pada tahun 2008, 2009 dan 2015, namun kekeringan terparah terjadi pada Agustus 2016.
Lessons Learned: Deformity Correction and Tibiotalocalcaneal Arthrodesis in a Patient With Glanzmann Thrombasthenia
Authors: Lam Kenrick , Janney Cory , Panchbhavi Vinod
Published: January 2020

Case:

A 33-year-old woman with Glanzmann thrombasthenia presented to us with a distal tibia nonunion. We attempted to treat her with a multiplanar ring external fixator, but the patient was unable to tolerate the correction, so we resorted to a tibiotalocalcaneal fusion. Hemostasis was difficult to achieve despite the use of antithrombinolytics, factor VII, and platelet transfusions.

Conclusion:

Bleeding can be difficult to control in patients with Glanzmann thrombasthenia. However, overaggressive preadministration of antithrombinolytics should be avoided because it may have adverse effects such as acrocyanosis. The presence of thrombasthenia does not seem to affect the success of arthrodesis.

Background: Penile squamous cell carcinoma (PSCC)represents an important public health problem for developing countries. The major prognostic factors in PSCC are pathological subtype, perineural invasion, lymphovascular invasion, depth of invasion and grade, which are hard to obtain precisely before the operation. Besides, micro-metastases will be detected in about 30% of intermediate-risk patients with clinically non-palpable inguinal lymph nodes after i nguinal lymph node dissection( ILND ) . It means approximately 70% of patients are unable to benefit from ILND who might suffered from the complications of surgery. We hope some biomarkers could be found which are able to predict the outcome before surgery and reflect the inguinal lymph nodes metastasis.
Methods: A total of 349 consecutive patients of penile cancer in Yunnan cancer hospital in China between October 2002 and December2017. 225 was succeed to follow-up. According to the (AUROC) curve, we get the cut-off point, K-M analysis and multivariate logistic regression models and Bivariate correlations were used to detect the results. The association between NLR,LMR,PLR,LDH and Overall survival(OS),progression free survival(PFS) , inguinal lymph node (N stage) was analyzed with K-M analysis, univariable, multivariable logistic regression and Kendall’s tau-b correlation coefficient.
Results: Multivariate analysis reveal that only PLR was significant independent factor which is associated with inferior OS and PFS; LDH was associated with inferior OS; Lymph node and metastatic status remained significant for OS and PFS as NCCN and EAU Guidelines indicated; the ages, tumor type, initial treatment and NLR LMR were not significant in predicting both OS and PFS. NLR, LMR and PLR were corresponded to N stage, while LDH was not associated with the N stage based on logistic regression model analysis. NLR, LMR and PLR were found weakly related to N stage through an application of Kendall’s tau-b correlation coefficient.
Conclusions: PLR was significant independent factors for OS and PFS, and LDH was significant independent factors for OS. NLR, LMR, PLR was corresponded to N stage.
Disabled and immigrant, a double minority challenge. A qualitative study about the experiences of immigrant parents of children with disabilities navigating the Norwegian healthcare system in general and the pediatric rehabilitation services in particular.
Authors: Arfa Shahrzad , Solvang Per Koren , Berg Berit , Jahnsen Reidun
Published: January 2020

Background: Immigrants and their Norwegian-born children make up approximately 18% of the total population in Norway. While several studies have been conducted on migrants’ utilization of healthcare services, immigrant families are systematically underrepresented in international studies of children with disabilities. This study, by focusing on experiences of immigrant parents of children with disabilities who are navigating the Norwegian healthcare system in general and the pediatric rehabilitation services in particular, will generate knowledge of how accessible and tailored the services are from their point of view. Methods: This study took a qualitative approach, using semi-structured interviews to explore the experiences of immigrant parents of children with disabilities from non-Western countries. The interviews were transcribed, coded, and analyzed via an inductive thematic analytic approach. Results: The findings show how the “immigrant experience” influenced the way the parents looked at, experienced, and even praised the services. The parents appreciated the follow-up services provided by the pediatric rehabilitation centers, which they experienced as predictable and well-organized. While navigating the services, they experienced several challenges, including the need for information, support, and timely help. They felt exhausted because of the years of struggle in the healthcare system to gain access to the help and services they needed. They expressed how this struggle had affected their own health. The feeling of being treated differently from the majority was another challenge they experienced while navigating the services. The findings also show how the parents’ experiences of communication with healthcare providers were influenced not only by their own language and communication skills but also by the healthcare providers’ intercultural communication skills and dominant organizational culture. Conclusions: The parents’ experiences show that there is still a gap between the public ideal of equal healthcare services and the reality of the everyday lives of immigrant families of children with disabilities. By exploring immigrant parents’ experiences, this study highlights the importance of mobilization at both the individual and system levels to fill the current gap and provide tailored and accessible services to the entire population. Keywords: Immigrant parents, Children with disabilities, Healthcare system.
Implementing self-management: a mixed-methods study of women’s experiences of a postpartum hypertension intervention (SNAP-HT)
Authors: Cairns Alexandra Elspeth , Tucker Katherine L. , Crawford Carole , McManus Richard J. , Powell John
Published: January 2020

Background
Self-management strategies are effective in a number of medical conditions; however, implementation studies have demonstrated adoption into clinical practice can be problematic. The process of implementation was explored during a pilot randomised controlled trial evaluating postpartum blood pressure self-management, in women with medicated hypertensive disorders of pregnancy.
Methods
A mixed methods study using semi-structured interviews with a qualitative and a scored (quantitative) component were undertaken as part of a pilot randomised controlled trial (SNAP-HT) in postnatal women with medicated gestational hypertension or pre-eclampsia. Women were randomised to usual care or blood pressure self-management. Self-management entailed daily home blood pressure monitoring and automated medication reduction via telemonitoring. Women from both groups optionally consented to participate in audio-recorded interviews, at four weeks and six months postpartum. Interview questions were developed to explore the proposed benefits of self-management and the constructs of Normalisation Process Theory. Participants provided a score (Likert scale 1-5) for each question and were encouraged to expand upon these answers through further discussion. The interviews were transcribed and analysed using the framework approach.
Results
Sixty-eight women, 34 from each randomised group, completed at least one audio-recorded interview. Several overarching themes emerged from analysis of 126 interview transcripts: control; convenience; confidence, communication and knowledge; concern; constraints; and components of the intervention. In the scored component of the analysis, both groups reported feeling more in control of their condition postpartum compared to during pregnancy, more so in those self-managing at both four weeks and six months: adjusted differences 0.6 (95% confidence interval (CI) 0.2 to 1.1) and 0.7 (95% CI 0.3 to 1.2) respectively.
Conclusions
Interviews and quantitative data showed that self-management enhanced women’s sense of control, and improved their blood pressure-related anxiety. Prior to taking part, a few women anticipated that home monitoring might increase anxiety, but stated that it had the opposite effect. Self-management was perceived as more flexible, reactive and as enabling more targeted down-titration of medication. These data provide considerable support for blood pressure self-management postpartum, and reinforce the effectiveness of the intervention used in this study.

Background: Body size traits as one of the main breeding selection criteria was widely used to monitor cattle growth and to evaluate the selection response. In this study, body size was defined as body height (BH), body length (BL), hip height (HH), heart size (HS), abdominal size (AS), and cannon bone size (CS). We performed genome-wide association studies (GWAS) of these traits over the course of three growth stages (6, 12 and 18 months after birth) using three statistical models, single-trait GWAS, multi-trait GWAS and LONG-GWAS. The Illumina Bovine HD 770K BeadChip was used to identify genomic single nucleotide polymorphisms (SNPs) in 1217 individuals.
Results: In total, 19, 29, and 10 significant SNPs were identified by the three models, respectively. Among these, 21 genes were promising candidate genes, including SOX2, SNRPD1, RASGEF1B, EFNA5, PTBP1, SNX9, SV2C, PKDCC, SYNDIG1, AKR1E2, and PRIM2 identified by single-trait analysis; SLC37A1, LAP3, PCDH7, MANEA, and LHCGR identified by multi-trait analysis; and P2RY1, MPZL1, LINGO2, CMIP, and WSCD1 identified by LONG-GWAS.
Conclusions: Multiple association analysis was performed for six growth traits at each growth stage. These findings offer valuable insights for the further investigation of potential genetic mechanism of growth traits in Simmental beef cattle.
A Post-market, Multi-vessel Evaluation of the Imaging of Peripheral Arteries for Diagnostic PurposeS Comparing Optical Coherence TomogrAphy and INtravascular Ultrasound Imaging (SCAN)
Authors: Pavillard Edward , Sewell Luke
Published: January 2020

Background: Intravascular imaging plays an important part in diagnosis of vascular conditions and providing insight for treatment strategy. Two main imaging modalities are intravascular ultrasound (IVUS) and optical coherence tomography (OCT). The objective of this study was to prove non-inferiority of OCT imaging to IVUS images in matched segments of peripheral vessels in patients with suspected peripheral vascular disease.
Methods: The SCAN study was a prospective, non-inferiority clinical study of matched IVUS and OCT images collected along defined segments of peripheral vessels from twelve subjects (mean age 68 10.3 years; 10 men) displaying symptoms of vascular disease. Luminal diameters were measured by both imaging systems at the distal, middle, and proximal points of the defined segments. Three blinded interventional radiologists evaluated the quality of both imaging modalities in identifying lMann-Whitney-Wilcoxon testing. Intrareader reproducibility was calculated by intraclass correlation (ICC) analysis.
Results: The mean scoringof plaque, calcification, and vascular stent struts by the three readers was significant better in terms of image quality for OCT than IVUS (p<0.001, p=0.001, p=0.004, respectively). The mean scores of vessel wall component visibility and artifacts generated by the two imaging systems were not significantly different (p=0.19, p=0.07, respectively). Mean vessel luminal diameter and area at three specific locations within the vessels were not significantly different between the two imaging modalities. No patient injury, adverse effect or device malfunction were noted during thestudy.
Conclusions: Imaging byOCT provides the physician with better visualization of some vessel and plaque chacteristics, but both IVUS and OCT imaging are safe and effective methods of examining peripheral vessels in order to perform diagnostic assessment of peripheral vessels and provide information necessary for the treatment strategy of peripheral artery disease.

Background: Microbial play important roles in kanef-degumming. This study aims at identifying the key candidate microbial and proteins responsible for the degumming of kenaf bast ( Hibiscus cannabinus ). Kenaf bast was cut into pieces and immersed into microbial fermentation liquid collected from different sites. Fermentation liquid samples were collected at 0, 40, 110 and 150 h and then subjected to the 16S/18S rRNA sequencing analysis and isobaric tag for relative and absolute quantitation (iTRAQ) analysis. The microbial (bacterial and fungal) diversity and the differentially expressed proteins/peptides (DEPs) were identified. Results: With the prolonged degumming time, the weight loss rate increased, the bacterial diversity was decreased. [Weeksellaceae], Enterobacteriaceae and Moraxellaceae were rapidly increased at 0~40 h, and then decreased and were gradually replaced by Bacteroidaceae from 40 h to 150 h. Similarly, Chryseobacterium and Dysgonomonas were gradually increased at 0~110 h and then decreased; Acinetobacter and Lactococcus were increased at 0~40 h, followed by decrease. Bacteroides was the dominant genus at 150 h. 18S rRNA-seq showed the gradually decreased Wallemia_hederae and increased Codosiga_hollandica during degumming. iTRAQ data analysis showed Rds1, and pyruvate kinase I was decreased and increased in the kanef-degumming, respectively. Other DEPs of ferredoxin I, superoxide dismutase and aconitatehydratase were identified to be related to the Glyoxylate and dicarboxylate metabolism (ko00630). Conclusions : Bacteria including Chryseobacterium , Dysgonomonas , Acinetobacter , Lactococcus and Bacteroides and fungi like Wallemia_hederae and Codosiga_hollandica are key candidate microbial for kanef degumming.

Published: January 2020

Background: The implication of microscopic ileitis finding in patients referred for ileocolonoscopy for clinically suspected inflammatory bowel disease is not well defined and its correlation with clinical outcome has not been fully studied. The current study aims to determine the prognostic yield of biopsies in this setting, and to evaluate the correlation of microscopic ileitis with long-term clinical outcome. Methods: Endoscopic reports of patients referred to our department for ileocolonoscopy in the years 2010-2016, as part of a diagnostic work-up for suspected IBD were reviewed. Patients with normal ileocolonoscopy were included, provided that terminal ileum biopsies were performed. Accordingly, patients were divided into normal (normal or reactive changes) and microscopic ileitis (inflammation or ileitis of any severity) groups. Both groups were followed prospectively to determine clinical outcome.Results: A total of 439 patients met the inclusion criteria. Sixty-four (14.6%) had inflammation on biopsy and were included in the microscopic ileitis group. Age and gender didn't differ significantly between groups. Overall follow up period was 6.1±2.3 years. Patients in the microscopic ileitis group were significantly associated with Crohn's diagnosis during follow-up period compared to normal (19% vs 2%, OR=11.98, 95%CI=4.48-32.01; p<0.01). Patients with granuloma or moderate-severe ileitis on biopsy were significantly associated with Crohn's development (100% vs 11%; P<0.01) compared to mild or nonspecific inflammation. Conclusion: Microscopic ileitis finding in clinically suspected IBD is associated with increased risk of future diagnosis of crohn's disease.
Comparative genomic analysis of the secondary flagellar (flag-2) system in the order Enterobacterales
Authors: De Maayer Pieter , Pillay Talia , Coutinho Teresa A
Published: January 2020

Background The order Enterobacterales encompasses a broad range of metabolically and ecologically versatile bacterial taxa, most of which are motile by means of peritrichous flagella. Flagellar biosynthesis has been linked to a primary flagella locus, flag -1, encompassing ~ 50 genes. A discrete locus, flag -2, encoding a distinct flagellar system, has been observed in a limited number of enterobacterial taxa, but its function remains largely uncharacterized.Results and Discussion Comparative genomic analyses showed that orthologous flag -2 loci are present in 592/4,028 taxa belonging to 5/8 and 31/76 families and genera, respectively, in the order Enterobacterales. Furthermore, the presence of only the outermost flag- 2 genes in many taxa suggests that this locus was far more prevalent and has subsequently been lost through gene deletion events. The flag -2 loci range in size from ~3.4 to 81.1 kilobases and code for between five and 102 distinct proteins. The discrepancy in size and protein number can be attributed to the presence of cargo gene islands within the loci. Evolutionary analyses revealed a complex evolutionary history for the flag -2 loci, representing ancestral elements in some taxa, while showing evidence of recent horizontal acquisition in other enterobacteria.Conclusions The flag -2 flagellar system is a fairly common, but highly variable feature among members of the Enterobacterales. Given the energetic burden of flagellar biosynthesis and functioning, the prevalence of a second flagellar system suggests it plays important biological roles in the enterobacteria and we postulate on its potential role as locomotory organ or as secretion system.

Published: January 2020

Background In the European Union (EU), informal caregivers provide 60% of all care. Informal caregiving ranges from assistance with daily activities and provision of direct care to helping care recipients to navigate within complex healthcare and social services systems. While recent caregiver surveys document the impact of informal caregivers, systematic reviews show that they have unmet needs. Because of the political desire to reduce the length of hospital stays, older patients are discharged from the hospital ‘quicker and sicker’ than before. The transition between different levels of the healthcare system and the period after hospital discharge is critical for elderly patients. Caregivers’ perspectives on the quality of older patients’ care journeys between levels of the healthcare system may provide valuable information for healthcare providers and policymakers. This study aims to explore older patient’s informal caregivers’ views on healthcare quality in the hospital and in the first 30 days after hospitalisation. Method We conducted semi-structured individual interviews with 12 participants to explore and describe informal caregivers’ subjective experiences of providing care to older relatives. The interviews were then transcribed and analysed thematically. Results The analysis yielded the overarching theme ‘Informal caregivers – a health service alliance – quality contributor’, which was divided into four main themes: ‘Fast in, fast out’, ‘Scant information’, ‘Disclaimer of responsibility’ and ‘A struggle to secure professional care’. The healthcare system seemed to pay little attention to ensuring mutual understandings between those involved in discharge, treatment and coordination. The participants experienced that the healthcare providers’ main focus was on the patients’ diseases, although the health services are supposed to view patients holistically. Conclusion Based on the information given by informal caregivers, health services must take into account each person’s needs and preferences. To deliver quality healthcare, better coordination between inter-professional care teams and the persons they serve is necessary. Health professionals must strengthen the involvement of caregivers in transitions between care and healthcare. Future work should evaluate targeted strategies for formal caregivers to cooperate, support and empower family members as informal caregivers.
