Abstract
To effectively mine historical data information and improve the accuracy of short-term load prediction, this paper aims at the characteristics of time series and nonlinear power load. Deep learning for load forecasting has received a lot of attention in recent years, and it has become popular in the analysis of electricity load forecasting. Long short-term memory (LSTM) and gated recurrent unit (GRU) are specifically designed for time-series data. However, due to the gradient disappearing and exploding problem, recurrent neural networks (RNNs) cannot capture long-term dependence. The Transformer, a self-attention-based sequence model, has produced impressive results in a variety of generating tasks that demand long-range coherence. This shows that self-attention could be useful in power load forecasting modeling. In this paper, to effectively and efficiently model the large-scale load forecasting, we further design the transform encoder with relative position encoding, which consists of four main components: single-layer neural network, relative positional encoding module, encoder module, and feed-forward network. Experimental results on real-world datasets demonstrate that our method outperforms the GRU, LSTM, and original Transformer encoder.

Abstract
The safety of the gas facilities is an important guarantee for the production and life of the society, and the monitoring of people entering the area is an important means to guarantee the safety of the facility. In order to solve the problem of non-contact monitoring of people entering the gas facilities, an Improved-Yolov4-tiny method is proposed in this paper. This method can be used to monitor people entering the area in real time and determine whether the type of person is a worker or non-worker based on characteristics such as clothing. Among them, the model increases a large-scale feature layer to improve the recognition and detection of small targets. The introduction of attention mechanism for multi-scale feature fusion increases the effectiveness of fine-grained detection of person. The Improved-Yolov4-tiny detection algorithm not only meets the requirements of real-time monitoring, but also achieves better results at different resolutions. Compared with the traditional Yolov4-tiny detection algorithm, the Improved-Yolov4-tiny detection algorithm improved the mAP metric by 3.1%.

Particularities of the interstitial atoms and vacancies clusters formation in a thin cadmium telluride foil during in situ electron irradiation in a TEM
Authors: Loginov Y Y , Mozzherin A V , Paklin N N 
Published: March 2022

Abstract
The formation of interstitial atoms and vacancies, as well as their clusters in the form of dislocation loops and voids in CdTe is simulated. The sizes and features of the growth of dislocation loops and voids were determined depending on the irradiation time, taking into account the decrease in the number of nodes of the semiconductor crystal lattice with the irradiation time, since in experiments we studied a thin CdTe foil in a transmission electron microscope (TEM). The calculated and experimental data are compared.

Published: March 2022

Abstract
Thin epitaxial films of garnet ferrite were studied using impedance spectroscopy. The influence of the magnetic field on the transport characteristics was investigated on the basis of the current-voltage characteristic characteristics (I-V) measured without a field and in a magnetic field H = 12 kOe. An increase in resistance in bismuth ferrite garnet was detected in a magnetic field at a temperature above room temperature.

Published: March 2022

Abstract
Intense navigation in the northernmost reaches of the Yenisei River during the Soviet era produced a rich industrial heritage. Among the more conspicuous objects are the remains of shore navigational aids, particularly leading lights and beacon towers. The surviving structures offer insights into the navigation methods used in this part of the Arctic. Navigational aides were also among the last industrial structures in the Soviet Arctic to be built of wood. Besides, they are important examples of structural engineering in the Arctic, meaning that they were designed to cope with the harsh environment.

Abstract
Simulation of the new exposure room shielding for Neutron Radiography Imaging (NURI) at 1 MW PUSPATI TRIGA MARK II (RTP) nuclear research reactor in Malaysian Nuclear Agency, Malaysia has been presented in this article. Previous exposure room shielding has to be disassembled due to various reasons such as radiation streaming problem and outdated since the exposure room was constructed in 1985. The NURI facility had been undergoing major upgrading for all their instrument including beam collimator, imaging system, sample positioning, instrumentation shielding, and exposure room shielding. This paper aims to simulate the radiation dose rate mapping for the new exposure room shielding for the NURI facility using the Monte Carlo simulation code of MCNPX. The exposure room shielding design consists of several modular blocks built from ordinary concrete and Ferro boron concrete. Ferro boron concrete is used to enhance the shielding performance of the facility. Results showed that exposure room shielding containing Ferro boron concrete manage to reduce the radiation by 1150 % at the critical area compared to ordinary concrete. The average radiation dose rate around the facility during operation at 1 MW reactor power ranging from 1 μSv/hr - 10 μSv/hr.

Abstract
The radiation and peroxide vulcanizations of natural rubber latex are sharing the same problem which is low mechanical properties on their latex. This makes it unsuitable to be use in the production of premium latex products such as surgical glove. Moreover, there are some cases where the use of sensitizers in radiation vulcanization and activators in peroxide vulcanization tends to produced latex film with unpleasant smell and darken color respectively during the drying process. For this study, radiation of latex formulations based on 0.1 pphr of tert-butyl hydroperoxide and 0.06 pphr of potassium laurate at various radiation doses showed increment of tensile strength with increasing of radiation doses; radiation at 25 kGy produced rubber film with tensile strength of 20.7 MPa which is almost 7 times higher than control.
Time dependent reliability analysis for a critical reactor safety system based on fault tree approach
Authors: Hassan Ahmad , Mokhtar Zahira , Maskin Mazleha 
Published: March 2022

Abstract
Loss of coolant in the operation of any nuclear power plant will eventually become the primary source of hazard in the sequence of events leading to reactor core uncovery. Subsequent failure in removing the nuclear decay heat and preventing the core uncovery will further lead to loss of coolant accident (LOCA). In conjunction to this safety concern, it is crucial that the reliability of the plant emergency core cooling system is systematically and critically analysed. This article presents a case study on the time dependent reliability analysis for a safety injection system (SIS) of an advanced pressurized water reactor, based on the failure mode and effect analysis (FMEA) and fault tree (FT) analysis approach. The identified generic data for component reliability are carefully reviewed and used in this study. Based on the base case model, sensitivity and importance measure analysis for basic events are performed and the outcomes gained are presented and discussed. From the analysis, it is shown that the safety injection pumps of the SIS contribute significantly to the reliability of the system. In the short (at 0.5 hour) and long (7.0 hours and 72.0 hours) run, safety injection pumps are critical and influence the reliability of the SIS the most. The SIS’s FT logic model that has been developed and calculated shows the usability of the FMEA and FT approach that are implemented in analysing SIS time dependent reliability.

Published: March 2022

Abstract
The study of rare earth and actinide elements have received attention nowadays due to rapid development in the extraction of the rare earth industry in Malaysia. Soil samples (18 areas) collected from the Kapar industrial area were analysed by using the neutron activation analysis (NAA) technique for the determination of rare earth elements and actinides (U, Th) concentration. The concentration of rare earth element such as La, Ce, Nd, Sm, Eu, Tb, Dy, Yb and Lu were ranged from 14.7-61.4, 30.6-132.8, 11.7-44.0, 2.12-9.60, 0.37-1.43, 0.03-1.57, 2.20-7.45, 0.28-0.81, and 1.99-4.15 mg/kg, respectively. The concentrations of uranium and thorium were a range of < 0.1-6.74 and 12.6-30.1 mg/kg, respectively. The results of geo-accumulation indicate the all-rare earth elements can be categorised as uncontaminated in all areas with an Igeo value below 0. The concentration of U can be categorised as uncontaminated to moderately contaminated (Igeo class 1) with Igeo values of 0 to 1 in the area of D, F, H, I, L, and N, whilst other areas can be categorised as uncontaminated with Igeo value < 0 (Igeo class 0). The thorium concentration in B, L, and N areas can be categorised as moderately contaminated with Igeo value 1 to 2 (Igeo class 2), whilst most of the area can be categorised as uncontaminated to moderately contaminated (Igeo values 0 to 1). The sources of Th contamination most likely originated from the anthropogenic and geogenic processes.

Authors: Davidson C , Zaw M K , Loh R , Grout C 
Published: March 2022

Abstract

Introduction
Within the Geriatric Medicine department at the Lister Hospital, Stevenage, the timeliness and quality of discharge summaries had become a source of complaints. Both primary care practitioners and families reported documentation was inadequate or incorrect. This project aimed to improve the quality of these discharge summaries in accordance with standards generated from previous audit data. Through improving communication it was clear that patient care could be enhanced.

Methods
Each month 15 discharge summaries were selected at random for review. Alongside patient notes these summaries were appraised in regards to standard discharge summary requirements: timeliness of delivery; adequate description of admission; and documentation of the follow up plan. They were also appraised on documentation of specific requirements for older aged adults including cognitive status, mobility status, discharge destination, need for home help, Rockwood Frailty score and resuscitation and escalation plans. Interventions including informal communication with junior doctors, circulation of a ‘Top Tips’ sheet, generation of an information poster and dissemination of information at local teaching sessions, took place, and were assessed, over regular PDSA cycles.

Results
showed a clear, sustained improvement in the quality of the discharge summaries. At the end of data collection, 100% of discharge summaries contained an adequate description of admission and an appropriate follow up plan. There was also significant improvement in documentation of specific requirements. Where documentation was initially very limited, following interventions, most discharge summaries contained details pertaining to discharge destination, need for home support, mobility status and resuscitation and escalation plans.

Conclusion
The relatively simple interventions have been found to have a sustained improvement in the quality of discharge summaries from the Geriatric Medicine Department at Lister Hospital, Stevenage. Whilst more work needs to be done it is hoped that this will already have enhanced patient care.
691 ‘ARE YOU CONCERNED ABOUT ME TODAY’ - AN MDT APPROACH TO IMPROVING DELIRIUM RECOGNITION
Authors: Bennett L , Boswell A , Huet H , Whitsey M 
Published: March 2022

Abstract

Introduction
Delirium is a common neuropsychiatric syndrome that increases the likelihood of adverse outcomes for patients admitted to hospital. Delirium is preventable and treatable. Recognition of the syndrome is challenging. Our aim was to increase this recognition through robust inpatient screening, utilising a multi-disciplinary team (MDT) approach.

Method
Stakeholder analysis for a quality improvement project revealed that junior doctors were members of the team most likely to perform a 4AT. Plan, do, study, act (PDSA) cycles were carried out: 1. Junior doctor engagement 2. Verbal prompts in huddle 3. Healthcare assistant (HCA) questionnaires.

Results
Baseline data showed that on average 0.6% patients had new 4AT over one week on elderly care wards. Intervention 1 involved 4AT handouts given to junior doctors. Number of 4ATs was 3% of patients per week. Intervention 2 used prompts in the morning MDT huddle, asking about concerns for patients. This increased the number of patients having 4AT per week to 6.5%. HCAs did not attend huddles and were targeted in the third intervention. A questionnaire with delirium information and the subsequent question ‘are you concerned about this patient’ was placed in patient bedside folders. This gave opportunity for HCAs to escalate patients to huddle so 4ATs could be carried out. The questionnaire was completed for 62% of patients, but only 1.4% patients were flagged up and subsequently had 4AT. This time was complicated however by the wards becoming Covid-19 wards.

Conclusion
Delirium is common however there is missed opportunity for earlier identification. Utilising HCAs with bedside questionnaires was time efficient and ensured robust escalation to prompt further investigation. When incorporated into huddle this could lead to more delirium diagnoses if carried out over a longer period, outside of the Covid-19 pandemic and on a ward solely populated with elderly care patients.
717 FLUSHI- AN INTERVENTION TO IMPROVE CATHETER CARE AND REDUCE UNNECESSARY CATHETERISATION DAYS
Authors: Anwyll N , Hyde K , Powell J 
Published: March 2022

Abstract

Introduction
Catheter-Associated Urinary Tract Infections (CAUTIs) are a common and preventable healthcare-associated infection that cost NHS hospitals an estimated £54.4 M per year. The risk of developing a CAUTI is intrinsically linked to the duration of an indwelling catheter. Our project was created in response to a clinical incident where a patient was mislabelled as having a long-term catheter (LTC) and discharged, subsequently enduring several unnecessary catheter days. We have created interventions with the primary aim of reducing the number of Short-term Catheters (STC) mislabelled as LTCs by 100%, and secondary aims of reducing the number of unnecessary catheter days, increasing the number of discharge summaries with correct catheter information and reducing the number of inappropriate catheterisations.

Method
All patients admitted to one Care of the Elderly from August 2020 with a new STC were included in this project. We designed the FLUSHI sticker as a tool for recording catheter care which specifically delineated between LTCs and STCs. In addition, it allowed space for recording essential catheter care and simplified the approach to indications for ongoing catheters. This was implemented alongside a Catheter Training Programme. Finally, specific catheter prompts were integrated into the discharge summary software to encourage the correct recording of catheter care on discharge. These data were compared with pre-intervention data to assess progression towards our aims.

Results
Provisional results have demonstrated a significant reduction in the proportion of patients with an STC mislabelled as having an LTC. In addition, we have seen a significant reduction in the number of unnecessary catheter days within inpatients.

Conclusions
The FLUSHI sticker is a valid intervention that allows for the delineation between STCs and LTCs, which in turn has reduced unnecessary catheter days, decreased the number of patients being mislabelled as having an LTC, and improved catheter communication on discharge.

Abstract

Introduction
Treatment Escalation Plans (TEP) detail appropriate ceilings of care and guide treatment of patients based on shared decision making. Whilst established in many acute trusts, TEP are not frequently used in community mental health hospitals. This is particularly concerning in organic mental health wards, where patients with severe dementia may be transferred to acute hospitals for treatment without consideration about whether this is appropriate. This quality improvement project aimed to develop and implement TEP within a community mental health hospital to support the management of our older patients with severe mental illness.

Methods
We designed a TEP form based on a prototype used in a partner acute trust and evaluated its use on our wards, comprising 20 patients between August–September 2020. We obtained quantitative data on use of TEP, including the length of time from admission to completion, as well as qualitative data from healthcare staff regarding their experience of using TEP.

Results
TEP implementation well received among members of staff. 100% of patients had a TEP in place within 2 weeks of admission. The mean time taken to complete a TEP was reduced from 7.1 days to 3.2 days following inclusion of the TEP proforma in admission packs. There was an improvement in understanding the purpose, comprehensiveness and location of TEP forms during their implementation. The key theme that arose from qualitative analysis of healthcare staff comments was that TEP forms provided clear guidance on appropriateness of escalation of care.

Conclusion
TEP forms offer clear guidance to treating clinicians about the ceilings of care for patients. TEP were successfully implemented in our community mental health hospital and we plan further post-implementation evaluation. We intend to roll out the TEP form across our mental health trust and share findings nationally to promote best practice.
