Descriptive Epidemiology From the Research in Osteochondritis Dissecans of the Knee (ROCK) Prospective Cohort

Background: Osteochondritis dissecans (OCD) occurs most commonly in the knees of young individuals. This condition is known to cause pain and discomfort in the knee and can lead to disability and early knee osteoarthritis. The cause is not well understood, and treatment plans are not well delineated. The Research in Osteochondritis Dissecans of the Knee (ROCK) group established a multicenter, prospective cohort to better understand this disease. Purpose: To provide a baseline report of the ROCK multicenter prospective cohort and present a descriptive analysis of baseline data for patient characteristics, lesion characteristics, and clinical findings of the first 1000 cases enrolled into the prospective cohort. Study Design: Cross-sectional study; Level of evidence, 3. Methods: Patients were recruited from centers throughout the United States. Baseline data were obtained for patient characteristics, sports participation, patient-reported measures of functional capabilities and limitations, physical examination, diagnostic imaging results, and initial treatment plan. Descriptive statistics were completed for all outcomes of interest. Results: As of November 2020, a total of 27 orthopaedic surgeons from 17 institutions had enrolled 1004 knees with OCD, representing 903 patients (68.9% males; median age, 13.1 years; range, 6.3-25.4 years), into the prospective cohort. Lesions were located on the medial femoral condyle (66.2%), lateral femoral condyle (18.1%), trochlea (9.5%), patella (6.0%), and tibial plateau (0.2%). Most cases involved multisport athletes (68.1%), with the most common primary sport being basketball for males (27.3% of cases) and soccer for females (27.6% of cases). The median Pediatric International Knee Documentation Committee (Pedi-IKCD) score was 59.9 (IQR, 45.6-73.9), and the median Pediatric Functional Activity Brief Scale (Pedi-FABS) score was 21.0 (IQR, 5.0-28.0). Initial treatments were surgical intervention (55.4%) and activity restriction (44.0%). When surgery was performed, surgeons deemed the lesion to be stable at intraoperative assessment in 48.1% of cases. Conclusion: The multicenter ROCK group has been able to enroll the largest knee OCD cohort to date. This information is being used to further understand the pathology of OCD, including its cause, associated comorbidities, and initial presentation and symptoms. The cohort having been established is now being followed longitudinally to better define and elucidate the best treatment algorithms based on these presenting signs and symptoms.
A field study on teat-end vacuum in different milking systems and its effect on teat condition

The amount of vacuum in the proximity of the teat depends on vacuum settings of the system but also on cross-section of milk and air lines, milking system components and design, as well as on, e.g., pulsation settings. The vacuum level has an influence on the speed of milk removal but also on teat barrier function and its ability to prevent infections of the teat canal and of the udder (Hamann et al. 1993). Due to the close interaction between teat, liner and vacuum, a response of the teat condition is a direct variable to evaluate improper design or settings of milking systems (Mein et al., 2003; Neijenhuis, 2004). The aim of the study was to investigate the amount of and variation in teat-end vacuum during milking, depending on milk flow and milking system characteristics, such as low and high placed milking line. Secondly, the aim of the study was to get a deeper insight into the interactions between milking system characteristics, pulsation settings and teat condition.

INFLUNCE OF DATE STONE MEAL PARTICLE SIZE AND FORM OF DIET ON MUSCOVY DUCKLINGS PERFORMANCE

A total of 180 Muscovy ducklings at 7 days of age were used in an experiment, which lasted 9 weeks. The experiment aimed to investigate the utilization of Date Stone meal (DSM) by using pelleting process and grinding and their interaction effects on growth performance of muscovy ducklings. Birds were divided into 4 equal experimental groups of 45 ducklings each. Every group was sub-divided into three replicates (15 ducklings / rep.). The first and second groups were fed the mash diet of coarse or fine DSM, while the third and fourth groups was fed pelted diets of coarse or fine DSM. The experimental diets were isocaloric and is nitrogenous. Results obtained could be summarized as follows: Muscovy ducklings fed pelleted diets of DSM had significantly (P < 0.01) highest average live body weight and body weight gain as compared with those received mash DSM diet. The grinding particle size and the interaction between dietary treatment had insignificant effects on performance. Moreover, Pellets form of DSM improved significantly (P < 0.01) feed conversion ratio (g feed/g gain) and fine DSM diet had improved significantly (P < 0.01) feed conversion ratio. Digestion coefficients of CP and CF showed a highly significant (P<0.01) increase for group fed fine pelleted DSM diet. Duckling fed coarse pelleted DSM diet had significantly ( P<0.01) highest digestive tract weight (g), Cecum length (cm), Liver% , Edible giblets % and had the highest insignificant Gizzard % as compared with other treatment groups. The highest value of economic efficiency among all experimental groups was recorded by group fed pellets form with fine grinding of DSM. From the nutritional and economical efficiency stand points of view, pelleting process with fine grinding of DSM could be recommended to be used successfully and safely in formulating diets for growing Muscovy ducklings raising under new reclaiming region without adversely affecting their growth performance.
Integrating modal-based NDE techniques and bridge management systems using quality management

The intent of bridge management systems is to help engineers and managers determine when and where to spend bridge funds such that commerce and the motoring public needs are satisfied. A major shortcoming which states are experiencing is the NBIS data available is insufficient to perform certain functions required by new bridge management systems, such as modeling bridge deterioration and predicting costs. This paper will investigate how modal based nondestructive damage evaluation techniques can be integrated into bridge management using quality management principles. First, quality from the manufacturing perspective will be summarized. Next, the implementation of quality management in design and construction will be reinterpreted for bridge management. Based on this, a theory of approach will be formulated to improve the productivity of a highway transportation system.

Analysis is carried out both theoretically and experimentally. The proposed antenna is designed to work in the X-band /spl sim/9.5 GHz. The return loss, radiation pattern, and antenna gain of the proposed antenna are presented and briefly discussed. The antenna has several advantages, such as ease of fabrication, good control of input impedance, small cross polarisation level, and high directivity.
Digital modelling and digital redesign of sampled-data uncertain systems

A new method for digital model conversion of a continuous-time uncertain system and a new digital redesign method for robust control of a sampled-data uncertain system are presented. The concept of the principle of equivalent areas together with interval arithmetic is utilised for finding the discrete-time uncertain model and the digital robust control law from the continuous-time uncertain state equation and the analogue robust control law, respectively. Using the newly digitally redesigned controllers, the resulting dynamic states of the digitally controlled sampled-data uncertain systems are able to closely match those of the original analogously controlled continuous-time uncertain systems for a relatively longer sampling period.
Acoustical characterization of a shallow water environment from sparse data

A new method for characterizing a region using limited acoustical and environmental measurements is proposed. The acoustical response from a moored vertical source array is measured along a receiving array. Using a generalized form of Huygens' principle, these fields can be merged with sparse in situ measurements and archival data. The objective is to produce a tightly constrained real time map of the coherent field and transmission loss in the volume. In the present work, alternative extrapolation procedures are examined. The effect of interaction with a lossy sediment layer is studied in a numerical simulation. <<ETX>>
The distribution of extended-spectrum Beta-Lactamase genes in Fomites, healthcare workers, and patients from two hospitals in Lagos state, Nigeria

Antibiotics resistance is a rapidly emerging issue through the misuse of antibiotics to treat human and animalrelated infections. The use of beta-lactams has increased considerably since its discovery so also resistant genes leading to Extended-Spectrum Beta-Lactamases (ESBL) mediated by the presence of blaCTX-M , blaTEM and blaSHV genes present in most Gram-negative bacteria. This study aimed to detect the widespread distribution of ESBL genes from fomites, healthcare workers, and patients suffering from urinary tract infection in two hospitals in Lagos state, Nigeria. A total of 150 swab samples were collected from fomites, health care workers, and cathetersof patients suffering from urinary tract infection (UTI). Antibiotics susceptibility test was performed by Kirby- Bauer technique according to CLSI guidelines. Organisms that tested positive phenotypically for ESBL were subjected to PCR for molecular analysis. ESBL prevalence rate of 21.8% and a carbapenemase-resistance rate of 16.7% were recorded. The ESBL producing isolates showed the highest resistance to ceftriaxone (82.4%) and the least resistance to tigecycline (5.9%). The existence of blaCTX-M and blaTEM was detected in 76.5% and 17.6% of the isolates respectively, while bla encoding gene was not detected in this study. The distribution of blaSHV genes detected in this study is of great concern which necessitates strict control measures in the usage of antibiotics especially the third-generation cephalosporin. In summary, the presence and distribution of ESBL encoding genes within two hospitals in Lagos were tested and the highest occurrence was recorded in blaCTX-M gene reducing and limiting the available treatment option for infections.
Characterization of Low Twist Yarn: Effect of Twist on Physical and Mechanical Properties

The amount of twist plays vital role for finished consumers' good which determines appearance, durability and serviceability of fabric. In this research, yarns made of four twists (170, 190, 210 and 230 tpm (turns per meter) were investigated in order to determine the effect of twist on physical and mechanical properties of low twist yarn. The yarn properties: tenacity, breaking force, elongation, mass variation, hairiness in the yarn were studied. Three counts (30, 40 and 50 tex) were manufactured with various twist levels. It was observed that the strength of yarn was affected with an increase of the twist and count. The yarn manufactured with 230 tpm and 50 tex count shows better yarn strength as compared with other twist levels and yarn counts. Further, it was found that reduction in twist improves the evenness of yarn.
Analysis of open-slot antenna radiation pattern using spherical wave expansion

This work explores the impact of the ground plane on a λ/2 open-slot antenna using the spherical wave expansion in the far-field zone. In terms of equivalent radiating sources, the nature of the open-slot antenna radiation pattern is not well assessed. This study shows that for small ground planes, open-slot antenna is a multiple source antenna.
Improved winding design for planar inductors

This paper examines design issues in low-profile inductors carrying high AC ripple current as well as large direct current for use in a 60 W power factor correcting power converter. Specifically, the effect of air gaps in the core structure on multilayer flex circuit (MFC) planar winding losses is examined. Some design guidelines for the construction of planar MFC windings that meet the desired goals of high power density and high efficiency are explored. The use of a flux "keep-away" region for the conductors of a planar winding design is modeled numerically. Experimental measurements of two MFC winding prototypes confirm the results of the numerical modeling.
Potential of innovative Dual CAS-MBR configurations in two very diverse market situations: Bulgaria and Cyprus

This paper reports on the first-order Aquafin analysis on the market potential of conventional and innovative MBR concepts for upgrading STPs which are non-compliant with European standards on urban wastewater treatment. The analysis looked at the feasibility of two innovative hybrid solutions comprising both an activated sludge plant with existing clarifiers and an MBR unit (the so-called “Dual” concepts). The upgrading potential will be illustrated throughout the description and analysis of two market situations lying at the extremes of the application spectrum, namely: Bulgaria, which is representative of compliance with the Urban Waste Water Treatment Directive standards, and Cyprus, which is iconic of strict, mandatory effluent standards for water reuse.
Analysis of signal degree of polarization degradation induced by polarization-mode dispersion in optical fibers

We study analytically and numerically optical signal degree of polarization (DOP) degradation induced by polarization-mode dispersion (PMD) in optical fiber transmissions, using the Eyal-Marshall-Tur-Yariv (EMTY) model and Monte Carlo simulations. The results show the inaccuracy of second-order PMD approximation in the EMTY model and the inapplicability of employing DOP as feedback signal for high-order PMD compensation.
Effect of Low-dose Aspirin on Neutrophil Apoptosis in Periodontitis: An Immunohistochemical Study

Aim and objective: A growing body of research today suggests that periodontitis is due to the failure of resolution pathways to restore homeostasis. Resolution is an active phenomenon of suppressing inflammation once its main objective of eliminating pathogens is achieved. Neutrophil apoptosis is an important step in promoting resolution. In chronic periodontitis, neutrophils linger for a long time in inflamed connective tissue and cause tissue destruction. Aspirin, a widely used anti-inflammatory and anti-thrombogenic drug, is known to cause neutrophil apoptosis by synthesizing aspirin-triggered lipoxin (15epiLXA4) a potent pro-resolving lipid mediator. This immunohistochemical investigation is designed to study the effect of low-dose aspirin therapy on neutrophil apoptosis in the gingival biopsies of patients suffering from periodontitis. Materials and methods: The study population consisted of 30 periodontitis patients who were divided into two groups of 15 each as test group and control group. Test group patients were on low-dose aspirin (75 mg/150 mg) therapy for clinical management of class 1 and class 2 functional capacity cardiovascular disease. Periodontal parameters like plaque index (PI), bleeding index (BI), probing pocket depth (PPD), and clinical attachment loss (CAL) were recorded, gingival biopsies were obtained from all patients for quantitative analysis of neutrophil apoptosis by immunohistochemistry using p53 as a marker of apoptosis. Chi-square/Fisher’s exact test was used to find the significance of study parameters on a categorical scale between two groups. Results: Results indicated that there was a decrease in PPD and CAL and a marginal increase in neutrophil apoptosis in the test group in comparison with a control group. Conclusion: Low-dose aspirin therapy may induce neutrophil apoptosis and improve PPD and CAL. Hence, it is presumed that it has the potential to be used as a host-modulating agent in the clinical management of periodontitis. Clinical significance: The low-dose aspirin could be used as a host-modulating agent in the management of periodontitis. Key messages: Increase apoptosis of neutrophils in the gingival biopsies of periodontitis patients who are on long-term low-dose aspirin therapy for CVD indicates that low-dose aspirin could be a potential host modality agent in the treatment of chronic periodontitis.
Individual Oligogenic Background in p.D91A-SOD1 Amyotrophic Lateral Sclerosis Patients

The p.D91A is one of the most common ALS-causing SOD1 mutations and is known to be either recessive or dominant. The homozygous phenotype is characterized by prolonged survival and slow progression of disease, whereas the affected heterozygous phenotypes can vary. To date, no genetic protective factors located close to SOD1 have been associated with the mild progressive homozygous phenotype. Using Next Generation Sequencing (NGS), we characterized a small cohort of sporadic and familial p.D91A-SOD1 heterozygous (n = 2) or homozygous (n = 5) ALS patients, to reveal any additional contributing variant in 39 ALS-related genes. We detected unique sets of non-synonymous variants, four of which were of uncertain significance and several in untranslated regions of ALS-related genes. Our results supported an individual oligogenic background underlying both sporadic and familial p.D91A cases irrespective of their p.D91A mutant alleles. We suggest that a comprehensive genomic view of p.D91A-SOD1 ALS patients may be useful in identifying emerging variants and improving disease diagnosis as well as guiding precision medicine.

A Six Sigma approach for R&D: measuring dissolved oxygen

A Six Sigma approach was applied to an R&D application with the goal of understanding and reducing measurement variability. Typically, Six Sigma is applied to a manufacturing process. Many aspects of processes and R&D applications are similar, e.g., input variables, measurements, and output values. In the current study, variables were identified, a gauge R&R test and Pareto analysis performed, and correction actions implemented to improve measurement variations. The gauge R&R study included an analysis of variances (ANOVA) using the Fisher test. The system under study was a new method to quantitate dissolved oxygen (DO) by colorimetry. Specifically, measurements were performed using a newly developed i–LAB® spectrometer. Various statistical and mathematical tools were employed to improve measurement variation, resulting in the standard deviation decreasing from 0.66 to 0.23. Additionally, the Six Sigma approach may be applied to other relevant R&D systems.
Marketing Fed Cattle Based on Expectations of the Underlying Carcass Value Dynamics

Abstract Fed cattle profitability is determined by complicated dynamic processes of body growth, carcass development, and seasonal prices. A structural model is constructed to contend with all these dynamic processes to predict optimal market timing. Informed simulations are conducted and compared to those observed in the data, as well as to a previous model ignoring the evolution of carcass value. The results indicate that significant improvements to profitability are attainable with the new method. The results also indicate the opportunity cost of not accounting for carcass value, even with error, is more severe than when these dynamics are ignored.
