Published: December 2019

The present study investigated the potential of native and modified sugarcane bagasse for the biosorption of Terasil Brown 2RFLfrom wastewater. The novelty of present work is the preparation of cost effective, efficient and eco friendly biosorbent for the removal of disperse dyeÂ usingÂ waste sugarcane bagasse after different simple and inexpensive physical and chemical treatments. The optimization of various physicochemical factors like pH, biosorbent dose, contact time, initial dye concentration and temperature was carried out in batch mode. It was observed that the biosorption capacity of native, CTAB treated and immobilized biosorbent was decreased fromÂ Â Â Â 54.78 to 34, 60.56 to 39.1 and 27.34 to 18.65 mg/g by decreasing pH from 2 to 9. The optimum pH was found to be 2. The reduction in biosorption of disperse dye from 75.4 to 12, 87.59 to 23.44 and 35.66 to 10.78 mg/g was found for native, pretreated and immobilized biosorbent by increasing the dose ofÂ biosorbent from 0.05 to 0.3g.Â Kinetic study showed the increase of dye removal by increasing the time from 5 to 90 min for native, CTAB treated and immobilized sugarcane bagasse respectively and there was not any effect on removal was observed after 90 min. At 90 min, the obtained biosorption capacities were 78.99, 89.22 and 38.99 mg/g for native, pretreated and immobilized biosorbent respectively. From the equilibrium study, it was found that the biosorption capacity was increased from 13.88 to 85.67, 20.88 to 94.65 and 10 to 56.77 mg/g by increasing the initial dye concentration from 10 to 100 mg/L. Thermodynamic study revealed the reduction in biosorption capacity from 76.55 to 49, 89.87 to 60 and 35 to 15 mg/g by increasing the temperature from 30 to 60 oC. The 0.05 g, 90 min, 100 mg/L and 30 oC were observed as optimum environmental conditions to attain the maximum removal of disperse dye from contaminated water using native, pretreated and immobilized sugarcane bagasse. The effect of salt, heavy metal ions was also studied on biosorption capacity to make this process more applicable on industrial scale because the contaminated water which discharged from industries mostly contained these ingredients in it. The well fitted equilibrium and kinetic models were found to be Langmuir and pseudo-second-order. Thermodynamic study showed the spontaneous and exothermic nature of biosorption process. The desorption study was also done to make this study more economical and environment friendly. From comparison of native and different modified forms of sugarcane bagasse, it was estimated that the CTAB treated sugarcane bagasse could be used as an efficient, environment friendly and cost effective biosorbent for the removal of Terasil Brown 2RFL from aqueous solution.

Published: December 2019

Uvod: Zdravstvena nega je znanstvena disciplina, zato morajo diplomirane medicinske sestre v prihodnosti z raziskovalnim delom slediti znanstvenoraziskovalnemu razvoju. Namen raziskave je bil ugotoviti odnos diplomiranih medicinskih sester do raziskovanja, s katerimi ovirami se srečujejo pri tem in v kolikšni meri se odločajo za raziskovalno delo.Metode: Uporabljena je bila kvantitativna neeksperimentalna metoda raziskovanja. Raziskava je bila izvedena s pomočjo strukturiranega vprašalnika med 110 diplomiranimi medicinskimi sestrami v zdravstveni dejavnosti na primarni in terciarni ravni. Zanesljivost vprašalnika je bila preverjena s koeficientom Cronbach alfa (Cronbach α = 0,72). Raziskava je bila izvedena v maju in juniju 2018. Uporabljeni sta bili opisna statistika in bivariatna analiza z Mann-Whitneyevim in Kruskal Wallisovim testom.Rezultati: Diplomirane medicinske sestre se v večini strinjajo (x = 4,23, s = 0,895), kako pomembno je, da zdravstvena nega temelji na dokazih. Oviro pri raziskovanju jim predstavljata znanje (x = 3,39, s =1,000) in pomanjkanje časa (x = 3,76, s = 0,877). Diplomirane medicinske sestre v zdravstveni dejavnosti na terciarni ravni so raziskovanju bolj naklonjene (x = 4,16) kot tiste na primarni ravni (x = 3,79, U = 1102,00, p = 0,008).Diskusija in zaključek: Diplomirane medicinske sestre se strinjajo, da je z dokazi podprta praksa v zdravstveni negi nujna. V raziskovanje se ne vključujejo zaradi pomanjkanja znanja, časa in pomanjkanja podpore sodelavcev. Za dvig ravni raziskovanja med medicinskimi sestrami je treba prenesti rezultate raziskav v prakso, izboljšati znanje medicinskih sester tako na področju raziskovanja kot uporabe pridobljenih rezultatov v praksi.
Modeling C2
n by Inclusion of Rainfall Parameter and Validate Modified Log Normal and Gamma-Gamma Model on FSO Communication Link
Authors: Kumar Suresh , Arora Payal 
Published: December 2019

Abstract
The Log Normal model for weak turbulences and Gamma-Gamma model for moderate to strong turbulences are being used for calculating the path losses for engineering Free Space Optical (FSO) communication link. Since FSO has been an attractive substitute to overcome the issues of RF spectrum license, high infrastructure cost and difficult terrains to ensure the availability of a network. Their application in mountainous and high density built up areas needs to be exploited. Atmospheric turbulence degrades the FSO communication performance arising due to variations in

Linguistic Landscape and Authenticity in a Japanese Supermarket in Singapore
Authors: Matwick Keri , Matwick Kelsi 
Published: December 2019

AbstractThis study examines the linguistic landscape of a Japanese supermarket in Singapore. Building on linguistic landscape research, this study focuses on cross-cultural, cross-linguistic, and cross-culinary exchanges that occur in food spaces. The analysis examines promotional signs and their image, text, typography, format, and the overall retail experience, allowing for a reading of “the semiotic landscape,” or how all the elements work together (Kress & Van Leeuwen 2006). What emerges is a dominant discourse of authenticity, identifiable by five types: original, natural, influential, referential, exceptional (Gilmore & Pine 2007), and we propose a sixth type of authenticity: health, which is particularly relevant to food. Health authenticity draws on science to inform consumers of nutrition but is made relatable to shoppers through folklore and local Singapore recipes. The use of Japanese is informative for Japanese shoppers while symbolic for non-Japanese shoppers of a Japan that is pure, authentic, high-quality, and significantly, healthy.
The Impact of Fiscal Policy on Economic Activity over the Business Cycle: An Empirical Investigation in the Case of Algeria
Authors: Chibi Abderrahim , Chekouri Sidi Mohamed , Benbouziane Mohamed 
Published: December 2019

Abstract
In this paper, we aim to analyze whether the effect of fiscal policy on economic growth in Algeria differs throughout the business cycle. To tackle this question, we use a Markov Switching Vector Autoregressive (MSVAR) framework. We find evidence of asymmetric effects of fiscal policy through regimes, defined by the state of the business cycle (recession and boom). The results show small positive government spending and revenue multipliers in the short term in both regimes. Most importantly, fiscal policy shocks have a stronger impact in times of economic recession than in times of expansion, which confirm the hypothesis of asymmetric effects. However, the impact of government spending is stronger than the impact of public revenue during recession periods. In addition, fiscal policy decision-makers interact with Anti-Keynesian view (pro-cyclical). Our results imply that there is something to gain by using the "right instrument" at the "right time".

Moreover, we give an algorithm for obtaining such a matrix. We analyze also the case where distances instead of quasi-distances are considered.
Toeplitz nonnegative realization of spectra via companion matrices
Authors: Collao Macarena , Salas Mario , Soto Ricardo L. 
Published: December 2019

Abstract
The nonnegative inverse eigenvalue problem (NIEP) is the problem of finding conditions for the existence of an n × n entrywise nonnegative matrix A with prescribed spectrum Λ = {λ
1, . . ., λn}. If the problem has a solution, we say that Λ is realizable and that A is a realizing matrix. In this paper we consider the NIEP for a Toeplitz realizing matrix A, and as far as we know, this is the first work which addresses the Toeplitz nonnegative realization of spectra. We show that nonnegative companion matrices are similar to nonnegative Toeplitz ones. We note that, as a consequence, a realizable list Λ= {λ
1, . . ., λn} of complex numbers in the left-half plane, that is, with Re λi
≤ 0, i = 2, . . ., n, is in particular realizable by a Toeplitz matrix. Moreover, we show how to construct symmetric nonnegative block Toeplitz matrices with prescribed spectrum and we explore the universal realizability of lists, which are realizable by this kind of matrices. We also propose a Matlab Toeplitz routine to compute a Toeplitz solution matrix.
QTL Mapping of Intestinal Neutrophil Variation in Threespine Stickleback Reveals Possible Gene Targets Connecting Intestinal Inflammation and Systemic Health
Authors: Beck Emily A , Currey Mark C , Small Clayton M , Cresko William A 
Published: December 2019

AbstractSelection, via host immunity, is often required to foster beneficial microbial symbionts and suppress deleterious pathogens. In animals, the host immune system is at the center of this relationship. Failed host immune system-microbial interactions can result in a persistent inflammatory response in which the immune system indiscriminately attacks resident microbes, and at times the host cells themselves, leading to diseases such as Ulcerative Colitis, Crohn’s Disease, and Psoriasis. Host genetic variation has been linked to both microbiome diversity and to severity of such inflammatory disease states in humans. However, the microbiome and inflammatory states manifest as quantitative traits, which encompass many genes interacting with one another and the environment. The mechanistic relationships among all of these interacting components are still not clear. Developing natural genetic models of host-microbe interactions is therefore fundamental to understanding the complex genetics of these and other diseases. Threespine stickleback (Gasterosteus aculeatus) fish are a tractable model for attacking this problem because of abundant population-level genetic and phenotypic variation in the gut inflammatory response. Previous work in our laboratory identified genetically divergent stickleback populations exhibiting differences in intestinal neutrophil activity. We took advantage of this diversity to genetically map variation in an emblematic element of gut inflammation - intestinal neutrophil recruitment - using an F2-intercross mapping framework. We identified two regions of the genome associated with increased intestinal inflammation containing several promising candidate genes. Within these regions we found candidates in the Coagulation/Complement System, NFkB and MAPK pathways along with several genes associated with intestinal diseases and neurological diseases commonly accompanying intestinal inflammation as a secondary symptom. These findings highlight the utility of using naturally genetically diverse ‘evolutionary mutant models’ such as threespine stickleback to better understand interactions among host genetic diversity and microbiome variation in health and disease states.

Published: December 2019

Case:
A 62-year-old man with no comorbidities presented with back and bilateral leg pain and progressive paraplegia that developed over a 1-week period. He had received 2 lumbar epidural steroid injections (LESIs) for lumbar stenosis 39 and 25 days before presentation. Workup revealed osteomyelitis of L4 and L5 with epidural abscesses. He ultimately underwent all-posterior L4 and L5 corpectomy with reconstruction and L1-pelvis arthrodesis, followed by 8 weeks of intravenous antibiotics. His weakness improved, but neurological deficits persisted.

Conclusions:
This case illustrates a catastrophic complication after LESI, resulting in permanent neurological injury in a patient with no apparent risk factors.
Loosening of a Total Hip Arthroplasty Associated with a Periprosthetic Femoral Fracture Caused by Recurrent Hydatidosis of the Hip
Authors: Masmoudi Karim , Ben Maitigue Mahmoud , Frikha Riadh , Mouelhi Thabet , Cheikhrouhou Hassen 
Published: December 2019

Case:
A 35-year-old woman, who lived in an endemic area for echinococcosis, developed a periprosthetic fracture with loosening of a total hip arthroplasty that had been performed 9 years earlier for hydatidosis of the right proximal femur with a pathological femoral neck fracture. At that time, the patient did not have any signs of liver or lung involvement. She was successfully managed by a cemented revision hip arthroplasty without any signs of recurrence at the last follow-up of 5 years.

Conclusions:
Total hip arthroplasty can offer effective management of proximal femur hydatidosis, despite the high rate of recurrence and mechanic failure.

Authors: Ellman Michael B. , Scheidt Michael , Skendzel Jack G. , Bhatia Sanjeev 
Published: December 2019

Case:
A 36-year-old 7ʹ0ʺ male professional basketball player presented with hip pain and radiographic imaging consistent with femoroacetabular impingement syndrome and a labral tear. Hip arthroscopy was performed with the patient positioned supine on a postless distraction table to negate the risk of pudendal nerve and perineal skin complications. Hip distraction was achieved with only 40 lbs (18.14 kg) of distraction force. Labral repair and cam osteochondroplasty were safely performed without complication.

Conclusions:
This case is the first to demonstrate that postless distraction may be considered for patients at end ranges of height that exceed the limitations of common hip arthroscopy tables.

Authors: Middleton A.H. , Martin J.M. , Wittmann T.A. , Schmeling G.J. 
Published: December 2019

Cases:
We present 2 cases of traumatic testicular dislocation associated with a pelvic ring injury after a motorcycle collision. Case 1 describes bilateral testicular dislocation discovered intraoperatively. Urology was consulted, and the testicles were manually reduced under general anesthesia. Case 2 describes unilateral testicular dislocation discovered at the 1-month follow-up after pelvic ring fixation. Concern for infarction prompted urology to take the patient for surgical reduction. Both cases resolved uneventfully without genitourinary complaints at the follow-up.

Conclusions:
Testicular dislocation is rare but should be considered in the setting of pelvic injury due to a motorcycle collision. Detection warrants urgent urologic consultation.

Abstract
Background Hepatitis C virus (HCV) infection is a leading cause of chronic liver disease and hepatocellular carcinoma. Treatment with first generation protease inhibitors (PI)+peg-interferon (pegIFN) and ribavirin (RBV) achieved sustained virologic response (SVR) rates of 65-75% but was associated with multiple side effects. The aim of this study was to evaluate safety and efficacy of Ombitasvir/Paritaprevir/Ritonavir and Dasabuvir (3D)±RBV in HCV genotype 1 patients that failed previous treatment with first generation PIs.Methods An investigator-initiated, open-label, multi-centre clinical trial. HCV Genotype 1 patients who were previously null/partial responders or relapsers to telaprevir, boceprevir or simepravir+pegIFN/RBV and met eligibility criteria were included. 3D±RBV were administrated for 12 or 24 weeks according to label. The primary outcome was antiviral response (SVR12); Secondary outcomes were patient reported outcomes, adverse events and resistance associated variants.Results Thirty-nine patients initiated treatment according to study protocol (59% men, age 54.0±8.7 years, BMI 28.7±4.5 kg/m 2 ). Thirty-seven (94.9%) completed the study. Thirty-five patients had genotype 1b (9 cirrhotics) and 4 had genotype 1a (2 cirrhotics). Intention-to-treat SVR12 was 92.3% and per-protocol SVR12 was 97.3%. The rate of advanced fibrosis (FibroScan ® score F3-4) declined from 46.2% to 25.7% (P=0.045). Abnormal ALT levels declined from 84.6% to 8.6% (P<0.001). Seven patients (17.9%) experienced serious adverse events (3 Psychiatric admissions, 1 pneumonia, 1 ankle fracture, 2 palpitations), and 12 patients (30.8%) experienced self-reported adverse events, mostly weakness.Conclusion 3D±RBV is safe and effective in achieving SVR among patients with HCV genotype 1 who failed previous first-generation PI treatment.Clinical trial number NCT02646111

Abstract
Background: The health-related quality of life (HRQoL) of adolescents with CP in low and middle-income countries is often poor, as is the case in Bangladesh. This exploratory study examined what factors predict the proxy-reported HRQoL of adolescents with CP in rural Bangladesh, a typical low- and middle-income country (LMIC). Methods: Adolescents with CP (10 to 18y) were identified using the Bangladesh Cerebral Palsy Register. HRQoL was assessed using the Cerebral Palsy Quality of Life-Teens proxy-report questionnaire (CPQoL-Teens), adolescent mental health using the Strengths and Difficulty Questionnaire (SDQ) and caregiver mental health using the Depression, Anxiety and Stress Scale (DASS-21). Theoretical and statistical interests (i.e. bivariate analysis, p <0.05) identified potential predictors which were entered into hierarchical multiple linear regression (HMLR) models in order of clinical significance; HMLR related adolescent clinical characteristics, adolescent and caregiver mental health and proxies of socioeconomic status to CPQoL-Teens dimensions. Results: 154 adolescents with CP (mean age 15y 1mo, SD 1y 8mo, female 31.2%) participated in this study. Twenty-four factors were identified to explore for relationship to adolescent proxy-reported HRQoL. Fifteen of the factors correlated to one or more CPQoL-Teens dimension; strongest correlation was between ‘feelings about functioning’ and motor impairment ( r =0.545). Nine were predictive of CPQoL-Teens dimensions; adolescent sex, school attendance, severity of motor impairment, hearing and speech impairment, mother’s education, primary caregiver depression and stress, and having a sanitary latrine at home resulting in score changes of between 0.79 (95% CI 0.24 to 1.35) to 35.1 (95% CI 6.03 to 64.22). Conclusions: Many of the factors predicting the proxy-reported HRQoL of adolescents with CP are amenable to intervention, and have the potential to improve adolescent wellbeing. Several determinants are priorities of the sustainable development goals (SDGs); these findings should inform resource prioritization to improve the wellbeing of adolescents with CP in Bangladesh and other LMICs.

Abstract
Background: Liver ischemia reperfusion (I/R) damage which is frequently seen in clinical hepatobiliary surgeries has no effective treatment for it. Liv-52, known to have hepatoprotective effects, is a natural antioxidant drug licensed by the Ministry of Health of India. The aim of our study is to investigate the effect of Liv-52 on liver damage induced by I/R in rats.
Methods: Albino Wistar male rats were divided into three groups; liver I/R (IR), 20 mg/kg Liv-52 + liver ischemia reperfusion (LIR) and sham operation applied to control group (HG). Liv-52 was administered to the LIR group (n=6) one hour prior to I/R application and distilled water was given orally to IR (n=6) and HG (n=6) groups as a solvent. Ischemia was determined as one hour, and reperfusion was identified as six hours in animals.
Results: Increased levels of alanine aminotransferase, aspartate aminotransferase and lactate dehydrogenase, malondialdehyde, myeloperoxidase, and decreased levels of superoxide dismutase, and glutathione related enzymes caused by I/R application have been converged to healthy group level with Liv-52 treatment and the damage in liver tissue has been improved histopathologically.
Conclusions: Liv-52 may be beneficial for preventing liver I/R damage in pre-surgery application.
