Analysis of Particulates and SO2 Removal from Coal Combustion Emissions Using Cyclone and Wet Scrubber With Textile Wastewater Feed
Authors: Huboyo Haryono S. , Sudarno Sudarno 
Published: January 2021

Reuse of wastewater in the industry is mostly accomplished for watering plants. In a closed cycle, however, industrial wastewater can be returned through treatment to save water usage. This study aims to analyze textile wastewater's ability to be used as scrubbing liquid in the SO2 gas and particulate removal from coal combustion using a packed wet scrubber. Usually, the textile industry uses boiler fueled by coal and discharging base/alkaline wastewater. The method is carried out experimentally using a prototype device using a combination of cyclone and scrubber, with a source of coal combustion gas emissions. We did experiments using textile wastewater four times and two times using clean water as a control. We monitor the SO2, particulate emission in the gas stream, and pH, sulfate levels, and TSS levels in collected wastewater according to SNI. SO2 gas and particulates from coal combustion will be absorbed by the scrubber's wastewater spray so that SO2 will dissolve into sulfate, particulate matter into TSS. The study results using textile wastewater showed the removal efficiency of particulates on cyclone by 34-78%. The removal efficiency of SO2 on wet scrubber was only 24.7%. There was an increase in TSS levels after passing through the scrubber by 46%. The rise in TSS and sulfate concentrations in the wastewater indicates the absorption of SO2 and particulates into wastewater. Based on this result, we can use textile wastewater for controlling the emission of SO2 and particulate from coal combustion by feeding it for the scrubber. However, the efficiency of this process is not optimal.
La consolidación electoral del desequilibrio territorial e identitario en España (2008-2016). Réplica al artículo "Las huellas electorales del nacionalismo español"
Authors: Portillo Daniel Romero , Ruiz Jiménez Antonia María 
Published: January 2021

El cambio del sistema de partidos y la profundización de éstos en la crisis territorial en el periodo posterior a la Gran Recesión de 2008 hacen interesante explorar también la polarización de la ciudadanía en el eje centro-periferia y la configuración del nuevo espacio electoral con respecto a este eje. El propósito de este artículo es conocer cómo se distribuyen las estructuras identitarias y a las preferencias sobre la organización territorial del Estado de las bases electorales de los partidos españoles bajo el nuevo contexto político-electoral. Para ello, se agregan los estudios post-electorales del CIS de 2008 a 2019, que se exploran de forma gráfica y mediante regresiones logísticas multinomiales. Nuestros hallazgos confirman que el deterioro apuntado por Jiménez y Navarro (2015) para las elecciones de 2011 no fue coyuntural, sino que se trata de una tendencia que se consolida desde 2015, estabilizándose hasta 2019. Específicamente, se consolida la erosión del apoyo al Estado de las autonomías y aumenta de manera general el apoyo centralismo. Esta erosión no va acompañada, sin embargo, de una desvinculación generalizada de las identidades compartidas, aunque aumenten las identidades nacionales exclusivas. En cuanto al nuevo sistema de partidos, las bases electorales de los partidos se polarizan en gran medida en cuanto a sus preferencias sobre la organización territorial del Estado, pero no así con la identidad nacional.

Authors: Hester Gabrielle Z. , Nickel Amanda J. , Watson David , Swanson Gloria , Laine Jennifer C. , Bergmann Kelly R. 
Published: January 2021

BACKGROUND:
Pediatric musculoskeletal infection (MSKI) is a common cause of hospitalization with associated morbidity. To improve the care of pediatric MSKI, our objectives were to achieve 3 specific aims within 24 months of our quality improvement (QI) interventions: (1) 50% reduction in peripherally inserted central catheter (PICC) use, (2) 25% reduction in sedations per patient, and (3) 50% reduction in empirical vancomycin administration.

METHODS:
We implemented 4 prospective QI interventions at our tertiary children’s hospital: (1) provider education, (2) centralization of admission location, (3) coordination of radiology-orthopedic communication, and (4) implementation of an MSKI infection algorithm and order set. We included patients 6 months to 18 years of age with acute osteomyelitis, septic arthritis, or pyomyositis and excluded patients with complex chronic conditions or ICU admission. We used statistical process control charts to analyze outcomes over 2 general periods: baseline (January 2015–October 17, 2016) and implementation (October 18, 2016–April 2019).

RESULTS:
In total, 224 patients were included. The mean age was 6.1 years, and there were no substantive demographic or clinical differences between baseline and implementation groups. There was an 81% relative reduction in PICC use (centerline shift 54%–11%; 95% confidence interval 70–92) and 33% relative reduction in sedations per patient (centerline shift 1.8–1.2; 95% confidence interval 21–46). Empirical vancomycin use did not change (centerline 20%).

CONCLUSIONS:
Our multidisciplinary MSKI QI interventions were associated with a significant decrease in the use of PICCs and sedations per patient but not empirical vancomycin administration.

Published: January 2021

Introducción. Los requerimientos de vitaminas B en rumiantes son satisfechos por su capacidad de síntesis a nivel ruminal. El mejoramiento genético, los avances en nutrición animal y los altos niveles de producción actuales, puede hacer que los animales no estén llenando sus requerimientos. Objetivo. Evaluar el efecto que tiene el uso de un complejo de vitaminas del grupo B sobre la producción láctea y el metabolismo de vacas lecheras en pastoreo. Materiales y métodos. Durante el segundo semestre del 2017, se utilizaron treinta vacas Jersey divididas en dos grupos que se mantuvieron durante dos periodos experimentales de 30 días. Durante el primer periodo de un mes, los animales del primer grupo recibieron 3,0 g diarios de un complejo de vitaminas B, mientras que los animales del otro grupo recibieron un placebo y para el periodo 2 se intercambiaron los tratamientos. Se midió la producción y composición láctea durante todo el periodo. Se midieron variables químicas como glucosa, betahidroxibutirato, aspartato amino transferasa, nitrógeno ureico y albúmina en sangre. Resultados. No se presentaron diferencias significativas (p>0,05) con respecto a la producción láctea. En el periodo 1, el grupo suplementado produjo 15,8 l por día; mientras que el grupo control produjo 16,1 l. Las concentraciones de grasa, proteína y lactosa en el primer periodo fueron de 5,0, 3,5 y 4,4 %, respectivamente. En el periodo 2, la producción láctea fue de 14,1 y 13,7 l para el grupo suplementado y no suplementado, respectivamente. En ningún periodo se observaron diferencias significativas (p>0,05) para los parámetros de química sanguínea analizados. La concentración de glucosa fue superior a 40 mg dl-1 y la concentración de betahidroxibutirato fue superior a 2,0 mmol l-1. Conclusión. Suplementar vacas Jersey con un complejo de vitaminas B de sobrepaso no mostró ventaja alguna con respecto a las variables productivas evaluadas.

Published: January 2021

El presente artículo reside en la investigación que se realizó en las Sedes Regionales de Educación Superior estatales ubicadas en Guanacaste. Se efectuó un análisis de los sistemas institucionales que utilizan las universidades en la formulación de proyectos de investigación y extensión. Se determinó que, aunque los procedimientos conllevan a un mismo fin, los sistemas de la Universidad de Costa Rica, Universidad Nacional y la Universidad Estatal a Distancia son muy diferentes, cuyo resultado no permite la compatibilidad tecnológica ni observar los proyectos que ejecutan las universidades públicas que las vinculan con la sociedad costarricense. Como corolario de la investigación, se propone un sistema con miras a integrar las plataformas tecnológicas y visibilizar los proyectos, en beneficio de la comunidad universitaria regional y nacional. Por lo cual es fundamental la coordinación de las direcciones de investigación y extensión de las Sedes Regionales con las Bibliotecas, para aprovechar sus capacidades en el tratamiento y diseminación de la información.

Objective: comparative assessment of long-term oncological results of laparoscopic extralevator and traditional abdominal-perineal resection (APR).Materials and methods. The analysis of immediate and long-term oncological results of treatment of 92 patients who underwent traditional laparoscopic and extralevator APR for low rectal cancer. Inclusion criteria were tumors of the lower ampullar rectum, excluding the performance of sphincter-sparing surgical interventions, and patients’ age up to 75 years. Exclusion criteria: distant metastases, histologically confirmed squamous cell carcinoma. Analysis of immediate and long-term results was carried out.Results. The main group included patients who underwent extralevator APR (n = 62), patients in the control group (n = 30) underwent traditional APR. There were no significant differences in the type of neoadjuvant and adjuvant treatment in the comparison groups (p >0.05). In the group of patients operated on in the volume of extralevator APR, 42 received neoadjuvant chemoradiotherapy versus 19 patients in the group of traditional APR, there was no statistically significant difference (p = 0.21). In the extralevator APR group, perineal plastic surgery was performed significantly more often than in the traditional APR group (p = 0.001). When evaluating the immediate results, there was a statistically significant difference in the total number of complications between the study groups, such complications as bladder dysfunction following after surgery, inflammatory pelvic disease in the perineal wound, perineal hernia occurred significantly more often in the traditional APR group than in the extralevator APR group (p >0.05). In terms of overall and disease-free survival, the groups differed statistically significantly: 5-year overall survival in the main group was 90 % versus 62.5 % in the control group (p = 0.03), 5-year disease-free survival in the main group was 98.5 % versus 65 % in the control group, respectively (p = 0.01).Conclusions. Extralevator APR of the rectum is the most radical surgical intervention than with the traditional APR technique due to the lower risk of a positive circumferention resection margin, therefore, reducing the incidence of local recurrence, and as a result, improving overall and disease-free survival rates compared to the traditional technique.

This system was applied to the Quantum network environment by this paper. This can achieve more compact than the conventional Quantum network environment.
Abnormal Use of Personal Pronouns in Sign Language of Autistic Deaf Children
Authors: Li Yangyang 
Published: January 2021

<p>Abnormal use of personal pronouns is an important feature of autistic children's oral development. After comparing autistic deaf children with autistic children and deaf children respectively, it is found that pronoun avoidance also exists in the sign language development of autistic deaf children, but pronoun reversal rarely occurs. In pronoun avoidance, the sign language performance of autistic deaf children is more similar to that of autistic children than deaf children, which is more likely to be due to autistic children's own disorders than differences in language forms. Different from autistic children and deaf children, autistic deaf children have their own unique performance in pronoun reversal: palm reversal. The reason may be that the disorder of personal pronoun reversal in autistic children may have different performance due to differences in language forms.</p>

Published: January 2021

Abstract
We evaluated the contribution of tumor volume (TV) to localized prostate cancer (PCa) patients’ prognosis. We retrospectively analyzed the data of 2,394 patients who underwent radical prostatectomy (RP) for localized PCa. The effect of TV volume on prostate cancer patients' prognosis was analyzed through Kaplan-Meier and Cox-proportional analysis. The mean prostate volume for all patients was 36.5 ± 15.4 cc, and the mean TV was 5.9 ± 8.3 cc. A significant positive relationship was observed between the classification by risk group in D’ Amico risk classification and the National Comprehensive Cancer Network risk group. (P < 0.001). The high TV showed significantly worse pathologic outcomes than the low TV in terms of high rates of extra-capsular extension, seminal vesicle invasion, and positive surgical margin (P < 0.05). The patients with high TV had significantly shorter biochemical recurrence-free survivals than those with low TV (P < 0.001). Finally, based on multivariate Cox-proportional analyses, TV was revealed to be an independent predictor of postoperative biochemical recurrence as both categorical (hazard ratio [HR]: 1.42, 95% confidence interval [CI]: 1.13–1.78, P = 0.003] and continuous variables (HR: 1.04, 95% CI: 1.04–1.05, P < 0.001). TV was revealed to be an independent prognostic factor in the postoperative biochemical recurrence. Patients with a high number of positive core and longer tumor length were significantly related to higher TV.
