Assessment of Aircraft Engine Blade Inspection Performance Using Attribute Agreement Analysis
Authors: Aust Jonas , Pons Dirk
Published: March 2022

Background—Visual inspection is an important element of aircraft engine maintenance to assure flight safety. Predominantly performed by human operators, those maintenance activities are prone to human error. While false negatives imply a risk to aviation safety, false positives can lead to increased maintenance cost. The aim of the present study was to evaluate the human performance in visual inspection of aero engine blades, specifically the operators’ consistency, accuracy, and reproducibility, as well as the system reliability. Methods—Photographs of 26 blades were presented to 50 industry practitioners of three skill levels to assess their performance. Each image was shown to each operator twice in random order, leading to N = 2600 observations. The data were statistically analysed using Attribute Agreement Analysis (AAA) and Kappa analysis. Results—The results show that operators were on average 82.5% consistent with their serviceability decision, while achieving an inspection accuracy of 67.7%. The operators’ reproducibility was 15.4%, as was the accuracy of all operators with the ground truth. Subsequently, the false-positive and false-negative rates were analysed separately to the overall inspection accuracy, showing that 20 operators (40%) achieved acceptable performances, thus meeting the required standard. Conclusions—In aviation maintenance the false-negative rate of <5% as per Aerospace Standard AS13100 is arguably the single most important metric since it determines the safety outcomes. The results of this study show acceptable false-negative performance in 60% of appraisers. Thus, there is the desirability to seek ways to improve the performance. Some suggestions are given in this regard.

Published: March 2022

Diabetic foot ulcer (DFU) is a severe complication of diabetes mellitus (DM). Patients with DFU have increased mortality and morbidity as well as decreased quality of life (QoL). The present scoping review aims to study the social issues of diabetic foot. Following PRISMA guidelines, the review was conducted in two databases (Scopus and Pubmed) with the use of the following keywords: “social aspects and diabetic foot”, “social characteristics and diabetic foot”, “social issues and diabetic foot”, “demographic profiles and diabetic foot”, “social determinants and diabetic foot”, “social capital and diabetic foot”, “social characteristics and gender and diabetic foot”, “social profiles and diabetic foot”, “social relationships and diabetic foot” and “social risk and diabetic foot”, from July to August 2021. Predetermined exclusion and inclusion criteria were selected. Forty-five studies (quantitative and qualitative) were eligible for inclusion in this review. Gender problems, socioeconomic status, social capital, and medical problems were the most important negative variables for diabetic foot. All the included variables reveal that the social impact of diabetic foot is the most important factor for management and prevention, in terms of aggravation and more, of the diabetic foot.

Published: March 2022

Research has shown that the COVID-19 pandemic has caused a mental health burden worldwide. Most studies have focused on the factors associated with a higher risk of mental health problems, and only a few studies have looked at the potential protective factors. The general objective of this study was to determine whether self-compassion has a protective effect against the risk of mental health problems and especially on perceived infectability. If so, we intended to determine which of the three specific facets of self-compassion (i.e., mindfulness vs. over-identification; self-kindness vs. self-judgment; common humanity vs. isolation;) has the greatest weight in predicting emotional distress. We conducted a cross-sectional study through an online survey completed by 855 participants in Spain. Results confirmed that the three facets of self-compassion reduce the negative correlation between perceived infectability and emotional distress, diminishing its role in predicting emotional distress. These results are discussed in relation to the protective role of self-compassion and the need to further explore the variables associated with a lower risk of mental problems derived from the SARS-CoV-2 pandemic.

Man overboard is an emergency in which fast and efficient detection of the critical event is the key factor for the recovery of the victim. Its severity urges the utilization of intelligent video surveillance systems that monitor the ship’s perimeter in real time and trigger the relative alarms that initiate the rescue mission. In terms of deep learning analysis, since man overboard incidents occur rarely, they present a severe class imbalance problem, and thus, supervised classification methods are not suitable. To tackle this obstacle, we follow an alternative philosophy and present a novel deep learning framework that formulates man overboard identification as an anomaly detection task. The proposed system, in the absence of training data, utilizes a multi-property spatiotemporal convolutional autoencoder that is trained only on the normal situation. We explore the use of RGB video sequences to extract specific properties of the scene, such as gradient and saliency, and utilize the autoencoders to detect anomalies. To the best of our knowledge, this is the first time that man overboard detection is made in a fully unsupervised manner while jointly learning the spatiotemporal features from RGB video streams. The algorithm achieved 97.30% accuracy and a 96.01% F1-score, surpassing the other state-of-the-art approaches significantly.
Verifiable Surface Disinfection Using Ultraviolet Light with a Mobile Manipulation Robot
Authors: Sanchez Alan G. , Smart William D.
Published: March 2022

Robots are being increasingly used in the fight against highly-infectious diseases such as the Novel Coronavirus (SARS-CoV-2). By using robots in place of human health care workers in disinfection tasks, we can reduce the exposure of these workers to the virus and, as a result, often dramatically reduce their risk of infection. Since healthcare workers are often disproportionately affected by large-scale infectious disease outbreaks, this risk reduction can profoundly affect our ability to fight these outbreaks. Many robots currently available for disinfection, however, are little more than mobile platforms for ultraviolet lights, do not allow fine-grained control over how the disinfection is performed, and do not allow verification that it was done as the human supervisor intended. In this paper, we present a semi-autonomous system, originally designed for the disinfection of surfaces in the context of Ebola Virus Disease (EVD) that allows a human supervisor to direct an autonomous robot to disinfect contaminated surfaces to a desired level, and to subsequently verify that this disinfection has taken place. We describe the overall system, the user interface, how our calibration and modeling allows for reliable disinfection, and offer directions for future work to address open space disinfection tasks.
Modification of Cycle Life Model for Normal Aging Trajectory Prediction of Lithium-Ion Batteries at Different Temperatures and Discharge Current Rates

Published: March 2022

Battery life is of critical importance for the reliable and economical operation of electric vehicles (EVs). Normal aging accounts for more than 80% of the battery available cycle range. Accurate and robust battery life models of normal aging are essential for battery health management systems and life evaluation before accelerated aging. Capacity recovery, test errors and accelerated aging all affect life model building during normal aging. Therefore, this paper proposes an improved life model based on wavelet transform (WT) signal processing to accurately predict the decline trend of the battery in the normal aging stage. In this paper, the capacity recovery, test noise and capacity diving in the aging trend are effectively removed by wavelet transform. We obtained an optimized life model through the analysis of the model structure and the analysis of the parameter sensitivity of the life model. The particle swarm algorithm (PSO) is employed to identify the parameters of the empirical models with the normal aging data extracted by the WT. Through verification, it is found that the modified cycle life model proposed in this paper can accurately predict the normal aging trajectory of batteries under different discharge rates and temperatures. The prediction error of the improved life model for normal aging is 1.09%.

Published: March 2022

Silkworm silk, which is obtained from domesticated
Bombyx mori
(
B. mori
), can be produced in a large scale. However, the mechanical properties of silkworm silk are inferior to its counterpart, spider dragline silk. Therefore, researchers are continuously exploring approaches to reinforce silkworm silk. Herein, we report a facile and scalable hot stretching process to reinforce natural silk fibers obtained from silkworm cocoons. Experimental results show that the obtained hot-stretched silk fibers (HSSFs) retain the chemical components of the original silk fibers while being endowed with increased
β
-sheet nanocrystal content and crystalline orientation, leading to enhanced mechanical properties. Significantly, the average modulus of the HSSFs reaches

21.6
±
2.8

 GPa, which is about twice that of pristine silkworm silk fibers (

11.0
±
1.7

 GPa). Besides, the tensile strength of the HSSFs reaches

0.77
±
0.13

 GPa, which is also obviously higher than that of the pristine silk (

0.56
±
0.08

 GPa). The results show that the hot stretching treatment is effective and efficient for producing superstiff, strong, and tough silkworm silk fibers. We anticipate this approach may be also effective for reinforcing other natural or artificial polymer fibers or films containing abundant hydrogen bonds.
Minimally Invasive Epicardial Ablation in Atrial Fibrillation: Evolution of Methods
Authors: Жигалкович А.С.
Published: March 2022

В статье освещена история развития мини-инвазивной эпикардиальной абляции при изолированной форме фибрилляции предсердий. Неоптимальные результаты использования антиаритмических препаратов и антикоагулянтов, невысокая эффективность катетерной абляции при непароксизмальных формах фибрилляции предсердий, травматичность операции Maze на открытом сердце с применением искусственного кровообращения привели к развитию торакоскопической эпикардиальной абляции. Первоначально основанная на изоляции только легочных вен эпикардиальная абляция со временем перешла в формат фрагментации левого предсердия, максимально повторяя операцию Maze. Эффективность торакоскопической эпикардиальной абляции значимо превосходит таковую при катетерной эндокардиальной абляции при непароксизмальных формах фибрилляции предсердий. Появление новых хирургических методов лечения фибрилляции предсердий создало основу для мультидисциплинарного подхода в лечении этой сложной аритмии и способствовало развитию гибридных технологий.

In the article, there is described the history of the development of minimally invasive epicardial ablation in isolated atrial fibrillation. Non-optimal results of the use of antiarrhythmic drugs and anticoagulants, low efficiency of catheter ablation in non-paroxysmal forms of atrial fibrillation, invasiveness of Maze open heart surgery using heart bypass resulted in the development of thoracoscopic epicardial ablation. Epicardial ablation, which was based initially only on isolation of the pulmonary veins, eventually developed into the left atrial fragmentation format, copying the Maze operation as much as possible. The effectiveness of thoracoscopic epicardial ablation significantly exceeds that of catheter endocardial ablation with non-paroxysmal forms of atrial fibrillation. The use of new surgical methods of treatment of atrial fibrillation created the base for multidisciplinary approach in the treatment of this complex arrhythmia and promoted the development of hybrid technologies.

Rice is a staple food source for most of the population of Indonesia and Asia. However, rice production has decreased over time due to the conversion of agriculture into industrial or residential areas. One strategy to increase production is to use high-yielding varieties and improve the cultivation system. Liquid smoke is one solution to neutralize acidity and maintain soil quality. This study aimed to test the effect of liquid smoke concentration on the growth and production of several rice varieties. This research was conducted in Plangwot village, Laren sub-district, Lamongan regency, in March - June 2021. The data analysis method used factorial randomized block design (RAK). The first factor is the variety of rice and the second factor is the concentration of liquid smoke. The results showed that each variety gave the best results at different concentrations of liquid smoke. The best treatment was found in the Inari 42 variety with a concentration of 2% liquid smoke, the Inari 32 variety with a 4% concentration, and the Ciherang varieties with a concentration of 2% and 4%. There is a tendency that increasing the concentration of liquid smoke to 4% results in a decrease in the growth and production of rice plants.

En este trabajo se aborda el relevamiento y análisis preliminar de los vestigios materiales correspondientes al fenómeno ferroviario, que pueden observarse en el paisaje ecotonal de la provincia de Buenos Aires. Las tareas se centraron en las estaciones de ferrocarril instaladas a fines del siglo XIX y a principios del siglo XX en los municipios de Florentino Ameghino, Rivadavia, Trenque Lauquen, Guaminí, Adolfo Alsina, Puan, Coronel Suárez, Coronel Pringles, Saavedra y Tornquist. El fenómeno ferroviario dejó huellas tanto en las zonas urbanas como rurales, convirtiéndose en un fuerte agente transformador del paisaje. Además, tuvo una implicancia fundamental en la fundación y desarrollo de los pueblos del área, en algunos casos también la decadencia de ambos procesos (urbanístico y ferroviario) estuvo entrelazada. La materialidad ferroviaria presenta características particulares que se plasmaron en las diversas estructuras construidas: estaciones, depósitos, talleres, refugios, apeaderos, lamparerías, tanques de agua y de combustible, nomencladores, cabinas de señales, garitas, sanitarios, servicios hospitalarios, casillas varias, viviendas para personal jerárquico y empleados de distintas categorías. Las variables estudiadas fueron tipo de construcción, estilo arquitectónico, materiales utilizados, tecnología aplicada, detalles ornamentales, red ferroviaria a la cual se integraba, entre otros. Por último, se consideró la valoración que se efectúa desde el presente hacia esta materialidad, registrándose el estado de conservación y deterioro de las estructuras remanentes, su integridad, la re-utilización y las prácticas contemporáneas de los edificios, con fines distintos a los cuales fueron concebidos.

Published: March 2022

Objective: To assess the frequency of ruptures of very small cerebral aneurysms, features of the perioperative period and outcomes, in comparison with the rupture of ordinarily sized aneurysms.

Material and methods: A comparative analysis of the group of patients with ruptured cerebral miliary aneurysms (n = 18) and the group of patients with ruptured cerebral aneurysms of regular size (n = 308) was carried out. All patients underwent open surgery in the first 3 days after the rupture (osteoplastic craniotomy, microsurgical aneurysm clipping). We compared gender, age of patients, severity of the patient’s condition at the moment of admission, severity of subarachnoid hemorrhage, location of aneurysms, aspect ratio, duration of the operation, frequency of intraoperative ruptures, postoperative mortality.

Results: It was found that miliary aneurysm rupture occurs in 5.5% of all patients with cerebral aneurysm rupture. The most common cases of rupture of very small aneurysms were in women (77.7%), with a mean age of 50.8 years. Aneurysms of the anterior communicating artery (66.6%) with a narrow neck (average aspect ratio – 2.1) were the most common. Patients with rupture of very small aneurysms were 7.9% more likely to be admitted in a state of subcompensation or decompensation (Hunt-Hess IV–V), they had massive subarachnoid hemorrhage (Fisher III) 19.6% more often than with ruptured aneurysms of regular size. On average, operations in cases of very small aneurysms lasted 30 minutes less than clipping of ordinary aneurysms, but were complicated by intraoperative rupture twice as often (38.8% and 16.5%, respectively). Postoperative mortality in the group of patients with ruptured miliary aneurysms was 5.7% higher than in patients with ruptured aneurysms of regular size.

Conclusion: Rupture of cerebral miliary aneurysms is relatively rare. Women of 50–60 years old with very small aneurysms of the anterior communicating artery with a narrow neck constitute the main group of such patients. Massive subarachnoid hemorrhage and severe condition of patients on admission are more common with miliary aneurysms than with ordinarily sized aneurysms. The small size of the aneurysm and the work near the rupture determine the more frequent contact intraoperative rupture when the neck is exposed as compared to operations on larger aneurysms, which negatively affects the treatment outcomes in this group of patients.
Estudio de la descomposición fotoquímica del ozono
Authors:   , Cobos Carlos Jorge
Published: March 2022

El ozono es una de las moléculas mus interesantes de la química inorgánica. Es muy reactivo y participa por eso en numerosas reacciones térmicas y fotoquímicas. Desde el punto de vista fotoquímico tiene un interés especial porque el estado electrónico de los productos de la disociación que sigue a la absorción de un fotón depende de la longitud de onda de la radiación absorbida. Esto permite estudiar el comportamiento químico de especies con distinto grado de excitación puesto que tanto el oxígeno atómico como el molecular poseen estados electrónicos excitados relativamente fáciles de alcanzar. También presenta un interés especial desde un punto de vista práctico. Se sabe que el ozono es un componente normal de la alta atmósfera que impide que radiaciones de longitudes de onda menores a 310 nm lleguen a la superficie de la Tierra. Estas radiaciones tienen un efecto letal sobre la vida terrestre.

Dari segi keilmuan, rasionalitas dogmatika hukum dijelaskan oleh teori hukum dan rasionalitas teori hukum dijelaskan oleh filsafat hukum, sehingga kedudukan filsafat hukum sebagai pemberi penjelasan ganda yang sangat mendalam terhadap rasionalitas dogmatika hukum. Dalam penulisan artikel ini, penulis menggunakan penelitian hukum normatif, dengan memanfaatkan bahan-bahan hukum sebagai dasar kajian untuk menjelaskan permasalahan. Hasil penelitian ini menegaskan bahwa filsafat hukum mengkaji tentang nilai, kepatutan, keseimbangan dan lain-lain. Teori hukum megkaji ajaran hukum, asas-asas hukum, konsep, adagium hukum dan lainnya. Sedangkan dogmatika hukum mengkaji tentang norma yang terdapat dalam aturan tertulis atau tidak tertulis yang ada dalam suatu sistem hukum.
Problematyka społeczna w twórczości Hakana Gündaya na przykładzie wybranych powieści
Authors: Haftka-Işık Dorota
Published: March 2022

Celem artykułu jest przedstawienie obrazu wycinka tureckiego społeczeństwa, jaki wyłania się z twórczości Hakana Gündaya, na podstawie dwóch powieści autora: Az (tytuł polski Mało, wyd. Sonia Draga, tłum. D. Haftka-Işık, 2016) oraz Daha (tytuł polski Jeszcze, wyd. Sonia Draga, tłum. D. Haftka-Işık, 2018). Hakan Günday (ur. 1976) to współczesny turecki prozaik, scenarzysta i dramaturg, którego twórczość w Turcji zaliczana jest do nurtu yeraltı edebiyatı (dosł. literatura podziemna). Jego powieść Jeszcze, za którą Günday został nagrodzony Prix Médicis (2015, Paryż, Francja) w kategorii „proza zagraniczna”, porusza aktualną tematykę społeczną, w tym przede wszystkim kwestię nielegalnych emigrantów i przemytu ludzi. Z powieści Gündaya wybrzmiewają takie tematy jak: piekło wojny i dramat uchodźców, problem dzieci-żołnierzy, handel ludźmi, bronią i narkotykami, przemoc, gwałt, wyzysk, wszelkie przejawy dyskryminacji, nierówności społeczne, demoralizacja, bezprawie, wykluczenie, ludzka niemoc, obojętność, zagubienie i samotność. Pisarz drąży genezę kondycji współczesnego świata i człowieka, a jego wielowymiarowa twórczość stwarza pole do interdyscyplinarnej analizy: socjologicznej, filozoficznej, kulturowej, psychologicznej czy językowej. Dzięki poruszanym w jego twórczości kwestiom społecznym powieści Hakana Gündaya można odczytywać w wymiarze społeczno-obyczajowym z zaznaczeniem, iż wyłaniający się wizerunek nie stanowi panoramy czy przekroju społeczeństwa tureckiego, a ukazuje jedynie jego wyimek, akcentując występowanie pewnych zjawisk oraz ukazując ich konsekwencje w odniesieniu do jednostki.

A RARE CASE OF PRIMARY HYPERTROPHIC OSTEOARTHROPATHY : CASE REPORT
Authors: Chauhan Vaibhavi , Trivedi Sangita , Patel Priti , Chaudhri Upendra
Published: March 2022

BACKGROUND: Hypertrophic osteoarthropathy (HOA) is characterized by abnormal growth of skin and osseous tissue at distal parts of the
extremities, also known as orphan syndrome and Pierre Marrie-Bamberger syndrome. The peculiar bulbus deformity of the digital tips known as
2
“clubbing”, periosteal proliferation of long bones and painful effusion of synovium. HOA can be primary(idiopathic) and secondary. Although
HOA is rare, secondary HOA is more common in certain diseases like chronic pulmonary disease, congenital heart disease, gastrointestinal disease,
5
and malignancies which may improve with treatment of the underlying disease. On the other hand primary HOA is idiopathic and its
pathophysiology remains unclear. When idiopathic HOA is associated with pachyderma (thickened skin) is known as pachydermoperiostosis. In
4
extremely rare instance idiopathic HOA may occur without pachyderma.
CLINICAL DESCRIPTION: We report a case of 4 years old female child came with complaints of pain and swelling in bilateral knee and ankle
joints since 2 years, and developed pain and swelling in elbow and wrist joint since 1 year. On general examination she has grade 4 clubbing in
ngers and toes. Suspecting HOA, relevant investigations sent to rule out secondary causes of HOA. After ruling out all causes of secondary HOA,
we arrive at diagnosis of primary (idiopathic) HOA.
MANAGEMENT: As there is no denitive management for primary HOA, we managed our patient symptomatically with painkillers.
CONCLUSION: Reporting a rare case of primary HOA without pachyderma treated symptomatically with NSAIDS.
PREVALENCE OF DYSLIPIDEMIA IN PATIENTS OF SUB CLINICAL HYPOTHYROIDISM AND THE EFFECTS OF THYROXINE REPLACEMENT THERAPY ON LIPID PROFILE IN NORTH INDIAN POPULATION
Authors: Kumar Randhir , Shakib Ahmad , Chaturvedi Mridul , Maurya Pavan
Published: March 2022

Subclinical hypothyroidism is a very common entity in Indian middle aged population with a prevalence of around 6-15%, dened as increase in
thyroid stimulating hormone (TSH) level without obvious rise in free triiodothyronine (FT3) and free thyroxine (FT4) level. However most of the
patients have an annual conversion of 5% into overt hypothyroidism. Replacement of thyroxine in these patients is always a controversial issue,
deranged lipid prole is an important indication of thyroxine replacement in these patients. In present study which is a case control study, we have
observed improvement in lipid prole after thyroxine replacement in patients of subclinical hypothyroidism with deranged lipid prole. In our
study there is a signicant improvement in total cholesterol, triglyceride, and LDL level without signicant improvement in HDL level after
thyroxine replacement.

Authors: Sharma Abi Manue , Vihan Sandeep , Agarwal Rahul
Published: March 2022

Introduction: Postoperative nausea and vomiting (PONV) has been variously described as the big little problem, the nal therapeutic challenge
for any anaesthesiologist.
Aims and Objectives: The main aim of this study is to evaluate and compare the antiemetic effects of gabapentin and ondansetron for prevention
of post operative nausea and vomiting (PONV).
Materials and methods: This study was carried out at Command Hospital (Eastern Command), Alipore, Kolkata (operation theatre and ward)
between Jan 2018 – May 2019. Patients of either sex, ASAgrade I and II, age between 20 to 60 years, body weight between 45 to 85 kgs, planned for
Elective laparoscopic cholecystectomy were chosen. PONV in rst 12 hours was measured at 1st hour, 3rd hour, 6th hour and 12th hour, and
1
calculation was done based on study carried out by Apfel et al . Taking an alpha error of 0.05 and a power of the study as 90%, the sample size was
worked out as 100 (50 in each group).
Conclusion: The results demonstrated that for decreasing the incidence of PONV, prophylactic use of 600 mg of Gabapentin two hours prior to
planned laparoscopic cholecystectomy is not superior to Ondansetron (which is the standard of care).
ASSOCIATION OF ALBUMINURIAAND URIC ACID IN PATIENTS WITH TYPE 2 DIABETES MELLITUS

Published: March 2022

Introduction: There are two possibilities of increase serum uric acid level it could be increase production or decrease excretion higher serum uric
acid level in diabetic nephropathy is mostly due to abnormality in uric acid excretion or hyperuricemia may result from increased net tubular
reabsorption. On the other hand, higher levels of serum insulin may decrease uric acid clearance by the kidneys. Today there is great interest in the
potential that uric acid may represent a remediable risk factor for CKD. So we studied the relation between hyperuricemia and albuminuria in type 2
diabetes mellitus patients in asansol district hospital west Bengal.Aims: The aim of this study is to evaluate the association between serum uric acid
& urinary Albumin to Creatinine Ratio (ACR) among patients with type 2 diabetes mellitus. Materials And Methods: This study was hospital
based observational and prospective study to nd out relationship between serum uric acid level & albuminuria in type 2 Diabetes Mellitus patients.
83 patients aged between 40 to 80 years was selected from Medicine OPD and indoor wards, Department of General Medicine, KPC Hospital, West
Bengal from 1august 2020 to 1august 2021. Type 2 Diabetics Melitus (T2DM) patients and Age: between 40 to 80 years were included in this study.
Result: 41(49.4%) patients had Normoalbuminuria, 26(31.3%) patients had Microalbuminuria and 16(19.3%) patients had
Macroalbuminuria.37(44.6%) patients had Hyperuricemia and 46(55.4%) patients had Normouricemia.25(30.1%) patients had ALT. Association
of hypertensive / normotensive vs. Albuminuria was not statistically signicant (p=0.3579).Association of hyperuricemia / normouricemia vs.
Albuminuria was statistically signicant (p<0.0001)..Poor control of HBA1C was signicantly associated with albumin excretion in urine
(p<0.0001).Distribution of mean GFR vs. albuminuria was statistically signicant (p<0.0001). Distribution of mean urinary ACR vs. albuminuria
was statistically signicant (p<0.0001). Distribution of mean serum uric acid vs. albuminuria was statistically signicant (p<0.0001). Conclusion
: Hypertension, raised HbA1C levels, high blood sugar levels and raised serum creatinine levels are the major risk factors. Hence early detection of
high risk patients and the early initiation of renal and cardiovascular protective agents helps in reducing morbidity and mortality due to type 2
diabetes mellites. There was negative correlation between serum uric acid with GFR and HDL, which were statistically signicant.
FIRST EPISODE OF SEIZURES WITH A FEBRILE ILLNESS IN CHILDREN AGED 6-18 MONTHS- SIGNIFICANCE OF LUMBAR PUNCTURE.
Authors: Muniyappa Vinod , Shrinidhi Chaitra
Published: March 2022

Background: Fever with seizures in children may be due to simple febrile seizure, complex febrile seizures or secondary to a neuroinfection. The
likelihood of acute bacterial meningitis (ABM) in febrile children with seizures ranges from 0.6% to 6.7%.
Objectives: To identify the group of 6-18 month old children with the rst episode of fever with seizure who would benet from cerebrospinal uid
(CSF) examination.
Method: The study group comprised 6-18 month old children, admitted with a febrile illness and rst episode of convulsion with the admission
occurring within 24 hours of the convulsion. Children with previously documented intracranial infection or neurological abnormality were
excluded.
Results: Of the 29 children included in study, 4 (13.8%) were diagnosed as having ABM. In the 6-12 month age group, 3 (25%) children had ABM
compared to one (6 %) in the 12-18 month age group. In the 6-12 month age group 2 of the 3 children with ABM had no meningeal signs and 1 had
meningeal signs. In the 12-18 month age group the child with ABM had meningeal signs. Signs of meningeal irritation had high specicity in
diagnosing ABM.
Conclusions: Lumbar puncture (LP) and CSF examination are important in ruling out ABM, when a child of age 6-18 months presents with rst
seizure associated with a febrile illness, particularly so in children aged 6-12 months. Whenever meningeal signs occur in such children, there is a
signicant chance of ABM.
Binary Spaghetti Sort and The Binary Spaghetti Heads Index
Authors: Calderone Alberto
Published: March 2022

Sorting items is a fundamental problem in computer science and algorithms design. Sorting algorithms can be divided in two categories, comparison based and non-comparison based, depending on the way they perform the sorting. Non-comparison based algorithms work on the nature of numbers, for instance, the fact that they are represented as decimal numbers. In this work, I present a stable non-comparison based sorting algorithm which exploits the binary numbers and bitwise operations to sort items. Due to its nature, this algorithm can be translated into an electrical circuit which can sort N + numbers in parallel.
