Nutrient modeling for a semi-intensive IMC pond: an MS-Excel approach
Authors: Ray Lala I. P. , Mal B. C. , Moulick S. 
Published: August 2017

Abstract
Semi-intensive Indian Major Carp (IMC) culture was practised in polythene lined dugout ponds at the Aquacultural Farm of Indian Institute of Technology, Kharagpur, West Bengal for 3 consecutive years at three different stocking densities (S.D), viz., 20,000, 35,000 and 50,000 numbers of fingerlings per hectare of water spread area. Fingerlings of Catla, Rohu and Mrigal were raised at a stocking ratio of 4:3:3. Total ammonia nitrogen (TAN) value along with other fishpond water quality parameters was monitored at 1 day intervals to ensure a good water ecosystem for a better fish growth. Water exchange was carried out before the TAN reached the critical limit. Field data on TAN obtained from the cultured fishponds stocked with three different stocking densities were used to study the dynamics of TAN. A developed model used to study the nutrient dynamics in shrimp pond was used to validate the observed data in the IMC pond ecosystem. Two years of observed TAN data were used to calibrate the spreadsheet model and the same model was validated using the third year observed data. The manual calibration based on the trial and error process of parameters adjustments was used and several simulations were performed by changing the model parameters. After adjustment of each parameter, the simulated and measured values of the water quality parameters were compared to judge the improvement in the model prediction. Forward finite difference discretization method was used in a MS-Excel spreadsheet to calibrate and validate the model for obtaining the TAN levels during the culture period. Observed data from the cultured fishponds of three different S.D were used to standardize 13 model parameters. The efficiency of the developed spreadsheet model was found to be more than 90% for the TAN estimation in the IMC cultured fishponds.

Abstract
In this study, surfactant modified zeolite-clinoptilolite (SMZ) by CPB (cetylpyridinium bromide) was used for simultaneous removal of ammonium, nitrate and phosphate in synthetic wastewater, and the sorption properties of SMZ were determined and compared with natural zeolite. Results showed that natural clinoptilolite had good affinity for ammonium (8.940 mg/g), but not for nitrate (0.427 mg/g) and phosphate (0.801 mg/g). With the increase of surfactant loading from 5 g/L to 40 g/L, the sorption capacity for nitrate increased from 0.462 mg/g to 4.661 mg/g. when the surfactant loading is 40 g/L, the SMZ has a phosphate adsorption capacity of 2.119 mg/g. The SMZ had a significant enhancement on nitrate and phosphate sorption, could simultaneously remove ammonium, nitrate and phosphate at specific conditions, with removal efficiency up to 85.2%, 83.1% and 56.7%, respectively. Orthogonal experiments showed that ammonium concentration was the most important factor for ammonium sorption on SMZ. Surfactant loading was the major factor for nitrate and phosphate sorption. With the increase of surfactant loading from 5 g/L to 40 g/L, the sorption capacity for nitrate increased from 0.462 mg/g to 4.661 mg/g. When the surfactant loading is 40 g/L, the SMZ has the best phosphate adsorption capacity 2.119 mg/g. Samples were characterized by X-ray diffraction (XRD) and Brunauer–Emmett–Teller (BET). Semi-empirical quantum mechanics molecular simulation indicated that electrostatic attraction existed between CPB and dihydrogen phosphate ion. Results indicate that SMZs might have great potential of removing cations and anions simultaneously in the aquatic environment, which is good for eutrophication control and nutrients removal.

Published: August 2017

El presente artículo invita a los investigadores y los prácticos facultativos a interrogarse, cada vez más, sobre los pasos factibles para valorizar, perpetuar, trasladar y crear el conocimiento organizativo. Esta investigación, de tipo mixto descriptivo, fue concebida para revisar los diversos procesos de la gestión del conocimiento en una empresa de la industria aeroespacial, ubicada en la ciudad de Querétaro. Para ello fue realizado un análisis acerca de la eficiencia de sus estrategias en el proceso de la gestión del conocimiento, apoyada por las Tecnologías de Información y Comunicación (TIC). La revisión del fenómeno de la gestión y la conversión del conocimiento consistió en evaluar su incidencia en la industria. La evaluación fue llevada a cabo bajo un caso de estudio en la organización KA (empresa estudiada), apoyándose en encuestas a directivos y empleados en general. Los resultados permitieron identificar las funciones sustantivas y administrativas dentro de la espiral de creación de conocimiento organizacional, en una dimensión epistemológica de creación de conocimiento organizacional. Uno de los principales aciertos de esta investigación fue la identificación del proceso de conversión del conocimiento, mediante la adaptación del conocimiento del personal. Lo que muestra la presencia de un consenso sobre la conversión y apropiación del conocimiento en la industria aeroespacial estudiada. Lo anterior resulta significativo, si se considera que la industria aeroespacial se estableció en Querétaro recientemente, esencialmente porque en la industria nacional existe una necesidad real de capitalizar y de explotar las informaciones nacidas de experiencias pasadas con el fin de mejorar la toma de decisiones y de crear nuevos conocimientos a partir de los recursos intangibles en las organizaciones.

In-Hospital Administration of Insulin by Nurses in Northern Greece: An Observational Study
Authors: Theofanidis Dimitrios 
Published: August 2017

Objective.
The purpose of this study is to explore current practice regarding insulin administration by nurses in a Greek public hospital.

Design and methods.
A mixed-methods qualitative data collection design was used with ad hoc nonparticipant observation and post hoc interviews with the staff involved. Insulin management and administration was observed and compared to international guidelines. A sample of 20 nurses from two medical wards was assessed on 100 occasions of insulin administration, and 8 nurses were subsequently interviewed.

Results.
Inter-rater agreement was found to be satisfactory (average κ 0.840). In 61% of all instances, nurses washed their hands before administering insulin, and, in 70%, they donned gloves before injections. In 64.5% of all instances, the nurses did not clean the insulin bottle before inserting the needle, and in 42.7% of instances, they did not check for air bubbles in the syringe. In 89.1% of instances, nurses did not check the injection site for appropriateness or other possible complications. However, in 90.9%, they cleaned the skin at the injection site with an alcohol swab. In 70.9% of all instances, the needle was placed vertically to the skin but without a skinfold. In 89.1% of instances, post-injection care was rated as poor.

Conclusion.
Overall, compliance with international guidelines regarding insulin administration techniques, as observed in these sample wards, is not satisfactory. Nurses in this Greek hospital tend to administer subcutaneous injections in ways not reflected in current research findings, practice guidelines, or evidence-based care recommendations. Evidently, Greek nurses in this sample require updating on current evidence-based practice, clinical guidelines, and protocols of care regarding routine insulin administration.

Background.. Intensive glycemic control confers increased risk of hypoglycemia and little benefit among older individuals with diabetes. The aim of this quality improvement project was to reduce the number of patients treated to A1C levels that might confer greater risk than benefit (i.e., potential overtreatment) in the VA New England Healthcare System.Methods.. A provider report and clinical reminder were created to identify potentially overtreated patients and prompt clinicians to consider treatment de-intensification. Potentially overtreated patients were defined as those on insulin or a sulfonylurea whose most recent A1C was &lt;7.0% and who were &gt;74 years of age or diagnosed with dementia or cognitive impairment. The numbers of patients screened and whose treatment was de-intensified using the clinical reminder were counted from January to December 2014. The number of high-risk veterans at baseline was compared with that 6 and 18 months after implementation using t tests.Results.. A total of 2,830 patients were screened using the clinical reminder; 9.6% had their glycemic treatment de-intensified. Among the 261 patients reporting hypoglycemia, 37% had their treatment de-intensified. Higher percentages of patients had treatment de-intensified when reported symptoms were more severe. The monthly average in the high-risk cohort declined from baseline by 18% at 6 months and by 22% at 18 months (both P &lt;0.005).Conclusions.. A clinical reminder helps clinicians identify and reduce the number of potentially overtreated patients. The large number of screened patients whose treatment was not de-intensified suggests that a clinical reminder should be combined with provider education, national guidelines, and performance measures aligned in the interest of reducing potential overtreatment.
Interventions to Improve Adherence to a Hypoglycemia Protocol
Authors: Destree Lani , Vercellino Mary , Armstrong Nancy 
Published: August 2017

Background.. A formal evidence-based hypoglycemia protocol and treatment algorithm were developed to provide safe and effective management of hypoglycemia throughout the hospital and to support organization goals to achieve blood glucose control. However, rechecking blood glucose 15 minutes after treatment for hypoglycemia, as outlined in the protocol, was challenging for the nursing staff. Education was delivered several times, and hypoglycemia badge reference cards were provided to reinforce the protocol. Nursing staff observed that hypoglycemia treatment took several minutes, so the recheck was set at 15–30 minutes from the time hypoglycemia was identified. Audits and staff reeducation were performed, but compliance remained low.
Objective.. A pilot was conducted to compare two innovative interventions to improve adherence to the protocol.
Methods.. To improve timely rechecks, two different interventions were tested. The first required patient care technicians (PCTs) to remain in the patient’s room for the full 15 minutes after treatment to perform the recheck. The second incorporated the use of timers to remind PCTs and nurses to perform the recheck.
Results.. The timer group had significantly higher compliance with hypoglycemia rechecks than the group staying in the patient’s room (84 vs. 52%, P &lt;0.0001). It is difficult for a PCT to remain in a patient’s room for a full 15 minutes. Timers enabled nurses and PCTs to perform other tasks without missing the recheck time. After implementation, the hospital achieved 75% compliance with the recheck.
Conclusion.. This project demonstrated that the use of timers can be an effective and efficient way to remind busy hospital staff to recheck a patient’s blood glucose after hypoglycemia treatment.
