Employing the Rhodobium marinum bacteria as an agent of hydrogen bioproduction with facultative fermentation condition needs two steps of cultivations, i.e., pre-culture and hydrogen production periods with different media.  The two steps cultivation is important state for hydrogen gas production rate. ASY (Ammonium, Succinate, and Yeast extract) is usually used as standard medium in biohydrogen production and mostly the component is analytical grade of chemicals. Series of cultivation media substitution by combining ASY with other cost-effective chemicals were investigated. The total of sixteen combinations of media were observed (P0-P15). Cultivation condition of R. marinum was set in an illuminated light of 31.17 µmol s-1m-2photon and agitated in shaker of 120 rpm for nine days. The experiment was designed as random selection with anova analyses. The results exhibited that P7 medium combination released the highest hydrogen gas of 61.29±0.52 ml/80 ml media among the others combination media. Using one-way ANOVA, there was a statistically significant difference between the mean number and condition and it was found P7 was significantly different with the others combination media, except P7 was insignificantly different with P3 only. Overall, the combination media is cheaper than the ASY medium. The ASY medium price is about USD 677, and the substitution media prices were ranging from USD 4.24 to USD 613.47. However, the further research on optimisation cultivation condition is needed.

Background: Shivering is an undesirable complication following general anesthesia and spinal anesthesia, whose early control can reduce postoperative metabolic and respiratory complications. Therefore, this study aims to compare the effects of prophylactic injection of ketamine and pethidine on postoperative shivering. Methods: This double-blind clinical trial was performed on 105 patients with short-term orthopedic and ENT surgery. The patients were randomly divided into three groups; 20 minutes before the end of the surgery, 0.4 mg/kg of pethidine was injected to the first group, 0.5 mg/kg of ketamine was injected to the second group, and normal saline was injected to the third group. After the surgery, the tympanic membrane temperature was measured at 0, 10, 20, and 30 minutes. The shivering was also measured by a four-point grading from zero (no shivering) to four (severe shivering). Data were analyzed by one-way ANOVA, Kruskal Wallis, Chi-square and Pearson correlation. Results: The mean age of patients was 35.8+/-11.45 years in the ketamine group, 34.8+/-11.64 years in the normal saline group, and 33.11+/-10.5 years in the pethidine group. The one-way ANOVA showed no significant difference in the mean age between the three groups (P=0.645). The incidence and intensity of shivering were significantly higher in the normal saline group than in the ketamine and pethidine groups (p=0.001). However, there was no significant difference in the incidence and the intensity of shivering between the ketamine and the pethidine groups (p=0.936). Conclusion: The results showed that the 0.5 mg/kg of ketamine could control the post-anesthetic shivering.

The study was conducted due to the economic importance of horses and shortage of information on electrocardiographic parameters of horses in Sokoto, Nigeria. This study established the normal electrocardiographic parameters of racing and non-racing horses in Sokoto and statistically compared the values. The study used forty horses comprising of 20 racing and 20 non-racing horses with mean age of 8 ± 0.5 years and average weight of 200 ± 2.0 kg. ECG was recorded using the base apex system with the animals in standing position using single lead channel ECG recorder (EDAN VE-100 manufactured by Edan instruments China). The paper speed was set at 25mm/s while the sensitivity of the machine was adjusted to 10 mm/mV. The durations and amplitudes of P, R and T, the durations of Q and S and the durations of PR, QRS and QT intervals were all determined. These parameters were determined for the three standard limb leads (I, II and III) as well as the augmented limb leads (aVR, aVL and aVF). Descriptive statistics using SPSS version 16 was used to calculate the means and standard error of mean at 95 % confidence interval. One-way ANOVA was used to compare between the values of the racing and non-racing horses. The highest values of P amplitude, R amplitude, Q amplitude, QRS complex and P-R interval were recorded in racing horses, while highest T wave amplitude was recorded in non-racing horses. Highest duration of P wave, T wave and QRS was recorded in racing horses while highest duration of Q wave was recorded in non-racing horses. Significant difference was found in the T amplitude in racing horses in lead aVF. The mean heart rate for the racing and non-racing horses was 80.3 ± 8.4 and 63.1 ± 9.2 beats/minute respectively. Higher values recorded in racing horses indicates that exercise has influence on electrical activities in horses. Keywords: Electrocardiograph, Non-racing horses, Parameters, Racing horses, Sokoto

Background: There is a need for improved primary palliative care (PC) education and resident comfort with providing end-of-life care. Objective: Utilize a new instrument derived from published PC competencies to assess baseline Internal Medicine (IM) resident knowledge and self-efficacy in PC to identify educational gaps and create new PC curricula. Design: We created a 2-part instrument including a Knowledge Test (KT) and a Self-Efficacy Inventory (SEI) addressing 18 PC resident competencies across 5 domains: Pain and Symptom Management (PSM), Communication (COMM), Psychosocial, Spiritual, and Cultural Aspects of Care (PSC), Terminal Care and Bereavement (TCB), and Palliative Care Principles and Practice (PCPP). Setting/Subjects: The instrument was emailed to IM residents at our institution during academic years 2015-2016 and 2016-2017. Measurements: Basic descriptive statistics were performed for the KT and SEI. Mean Rank Analysis and One-way ANOVA were utilized for the KT and SEI, respectively. Congruence was calculated between knowledge and self-efficacy. Results: The mean score on the KT was 73% (range 33-80%). There was no significant difference in knowledge among post-graduate year cohorts. Self-efficacy scores were lower for interns overall and in PCPP, TCB, and COMM domains. Knowledge was concordant with self-efficacy in 42% of participants, higher than self-efficacy in 10% of participants, and lower than self-efficacy in 48% of participants. Conclusions: For approximately half of respondents, high self-efficacy in PC did not correlate with high PC knowledge. A more focused curriculum is needed to help IM residents facilitate mastery of PC competencies by graduation.

Abstract Background The term ‘tandem spinal stenosis’ (TSS) was first introduced by Dagi et al to describe concurrent symptomatic cervical and lumbar spinal stenosis. A typical clinical picture includes intermittent neurogenic claudication, myelopathy, and polyradiculopathy in both the upper and lower extremities. The incidence of TSS ranges from 0.12 to 28%. Methods We studied patients who presented with tandem canal stenosis and operated cervicolumbar decompression with or without fusion procedures by two separate neurosurgical teams simultaneously from June 2015 to 2017 with follow-up period of minimum 6 months. Results We had 30 (66.66%) male and 15 (33.33%) female patients who underwent simultaneous cervical and lumbar spine surgeries. The average age was 57.8 years (male) and 53.9 years (female). Cervical canal stenosis was graded as per magnetic resonance imaging (MRI) morphological grades of stenosis by Kang et al and lumbar grading, was done as per Schizas et al grading system. The mean duration of complaints in cervical and lumbar compression was 29.54 ± 44.99 months and 30.55 ± 38.11 months, respectively. The mean preoperative Japanese Orthopaedic Association (JOA) score of was 10.46 ± 1.39, whereas the postoperative mean JOA score was 11.93 ± 1.28, and mean preoperative (38.59 ± 16.52) and postoperative (29.22 ± 9.38) Oswestry Disability Index (ODI) scores showed a statistically significant difference (p = 0.0001). Conclusion Patients with TSS are elderly and have associated comorbidities, still simultaneous cervical and lumbar surgery is feasible with the good outcome if you have two neurosurgical teams operating simultaneously and having good other super specialty teams’ support. It can be timesaving and cost effective for patients. Also, it avoids patients from undergoing exposure to two separate surgical and anesthetic stress.

The effect of thermoforming on the tear strength of ethylene vinyl acetate (EVA) mouthguard material (Bioplast®) has not been widely investigated. The present study compared the tear strengths of non-processed and processed EVA specimens in various thicknesses. Two groups of EVA sheet (non-processed and processed) in three different thicknesses of 3, 4 and 5 mm were used in specimen fabrication. The processed EVA sheets were achieved by forming the EVA sheet on the cylindrical stone model with the pressure-molding device (Biostar®). Twelve of tear strength specimens of non-processed and processed group in each thickness were prepared following the modified ASTM D 624-00 guideline. The tear strength test was conducted using universal testing machine (Lloyd® 1K series) with the speed of 500 mm/min. The mean thickness and tear strength of the non-processed and processed specimens in each thickness were compared using independent T-test. The differences in the mean tear strength for each thickness of non-processed and process specimens were determined using one-way ANOVA. The mean tear strength and mean thickness of processed EVA specimens was significantly lower than the non-processed EVA specimens for every thickness (P ≤ 0.05). There was no significant difference in the mean tear strength of EVA specimens among each thickness in both non-processed and processed groups. It can be concluded that the thermoforming process has the significant effect on the tear strength of the EVA mouthguard material formed by pressure molding device in every thicknesses. The tear strength of processed specimens were significant lower than the non-processed. Thus, it is more relevant for testing properties of the processed mouthguard material that the mouthguard material before processing.

ObjectiveTo assess the quality of eyeglass prescriptions provided by an affordable wavefront autorefractor operated by a minimally trained technician in a low-resource setting.Methods and Analysis708 participants were recruited from consecutive patients registered for routine eye examinations at Aravind Eye Hospital in Madurai, India, or an affiliated rural satellite vision centre. Visual acuity (VA) and patient preference were compared between trial lenses set to two eyeglass prescriptions from (1) a novel wavefront autorefractor and (2) subjective refraction by an experienced refractionist.ResultsThe mean±SD VA was 0.30±0.37, –0.02±0.14 and −0.04±0.11 logarithm of the minimum angle of resolution units before correction, with autorefractor correction and with subjective refraction correction, respectively (all differences p<0.01). Overall, 25% of participants had no preference, 33% preferred eyeglass prescriptions from autorefraction, and 42% preferred eyeglass prescriptions from subjective refraction (p<0.01). Of the 438 patients 40 years old and younger, 96 had no preference and the remainder had no statistically significant difference in preference for subjective refraction prescriptions (51%) versus autorefractor prescriptions (49%) (p=0.52).ConclusionAverage VAs from autorefractor-prescribed eyeglasses were one letter worse than those from subjective refraction. More than half of all participants either had no preference or preferred eyeglasses prescribed by the autorefractor. This marginal difference in quality may warrant autorefractor-based prescriptions, given the portable form factor, short measurement time, low cost and minimal training required to use the autorefractor evaluated here.

In this study, it is aimed to analyze attitudes of obese students in high school towards physical education according to some variables. 74 secondary education student, 45 of them are girls and 29 boys who studied at three different Anatolian High Schools in the city of Niğde in the 2016-2017 academic year, have been participated in this study. As data collection tool, Physical Education attitude scale for secondary education students developed by Güllü and Güçlü (2009) has been used and coefficient of consistence (Cronbach Alpha) is 0,94. SPSS 23.0 packaged software has been used for assesing the result. Kolmogorov – Smirnov Test have been done regarding whether the data showed normal distribution or not and Kurtosis and Skewness values have been studied. Independent Sample T Test has been used to test the mean difference significance belonging to two group independent variables in the study. One Way ANOVA Test has been used to test the mean differences significence when the number of groups is more than two. At the end of the study, all of the attitude scores belonging to variables have been found high and it has been established that obese high school students’ attitudes towards Physical Education show statictically significant difference, according to gender, in favor of boys (p<0,05). Accordingly, it has been determined that students’ cognitive attitudes acording to obesity level for Physical Education show difference in favor of second grade obese students (p<0,05) and no significent difference found in students’ affective and behavioural attitudes (p>0,05). It has been identified that high school students’ attitudes towards Physical Education show no statistically significant difference according to their calass level variable and time variable which they spent with their communication instruments (p>0,05) As a result, when considering obese students’ positive attitudes towards physical education and sports, in view of obtained findings, it is possible to say that physical education and sports may contribute to increase the participation of obese students and thus make them become healthy individuals.Extended English summary is in the end of Full Text PDF (TURKISH) file. ÖzetBu araştırmada, lise düzeyinde öğrenim gören obez öğrencilerin beden eğitimi dersine yönelik tutumlarının bazı değişkenlere göre incelenmesi amaçlanmıştır.

The use of burnt-clay bricks is increasing in rural areas because of its availability and low cost. However, the burning of bricks locally at unknown temperatures will likely result in the production of bricks that are unfit for construction purposes. The study assesses the minimum number of days bricks require to attain the minimum stipulated standards for compressive strength and water absorption. The results obtained were compared to the NIS 87: 2000 standards to assess their conformity. From the study results, the mean compressive strength of bricks (1.576 N/mm², 2.306 N/mm², 3.634 N/mm²) at 48, 72 and 96 hours of firing fails to attain the target value of 5N/mm² as stipulated by the NIS building code. However, the mean compressive strength after 120 hours (5.386 N/mm²) attains the stipulated unit value. The water absorption rate displayed similar findings with mean values of 37.12%, 34.2%, 28.88% failing to conform with the stipulated 20% standards. However, the mean of water absorption after 120 hours (21.02%) has no significant difference and hence conforms to the stipulated value. This therefore means that bricks should be burnt far beyond the 120 hours in order to safely conform to 5N/mm² and 20% compressive strength and water absorption respectively.

Background: Present study was undertaken to do a comparative evaluation of artificial rupture of membrane (ARM) and spontaneous rupture of membrane (SRM) on the course of labour and feto-maternal outcome.Methods: It was prospective interventional randomized comparative study including 120 primigravidae (60 in ARM and SRM group each) with cervical dilatation ≥3 cm and intact membranes. Amniotomy was performed in ARM group after enrolment while no intervention in SRM group. Outcomes noted were duration of labor, mode of delivery, APGAR score, NICU stay.Results: Significant reduction seen in duration of labour in ARM group (p=0.0001). Mean duration of labor was 5.24 hours in ARM group while 6.94 hours in SRM group. No significant difference noted in mode of delivery (p=0.082). No significant adverse feto-maternal outcomes were seen with amniotomy. APGAR score and NICU admission had no significant difference among the two groups.Conclusions: ARM can be opted as an intervention with shorter duration of labour without adversely affecting the feto-maternal outcomes. It is safe, reliable and cost effective modality when employed in primigravida and may be considered as a low-cost accessible intervention to reduce prolonged labour and its associated complications.
