Auditory localisation of conventional and electric cars: Laboratory results and implications for cycling safety

High-filler-content paper is a growing research and development opportunity in papermaking. These new products must address traditional paper product properties while providing papermakers with distinct product platform benefits. Over the past decade, a research team involving researchers from the Institute of Paper Science and Technology at Georgia Institute of Technology and from Imerys have significantly advanced the application of starch-encapsulated papermaking fillers. This review summarizes these accomplishments from initial laboratory studies to mill trials. Laboratory results have illustrated that starch-encapsulated fillers can facilitate a near-doubling of filler content over conventional levels at equal tensile and z-direction tensile (ZDT) values. Equally important is that the use of starch-encapsulated kaolin (SEK) filler has been shown to facilitate a doubling of filler addition rate without any detrimental impact on ring crush compared with control studies with filler. Pilot-plant and mill trials have shown that SEK can function as a fiber extender, reduce steam demand for drying by 10%, and increase papermaking speeds and production rates.

Laboratory Results

Retention of cationic dispersed rosin size was studied via turbidity measurements on stock filtrate with different alum and dispersed rosin size dosages. Stock charge characteristics were analyzed using both an analysis of charge demand determined via a streaming current detector and an evaluation of zeta potential of the fibers by streaming potential measurement. The results indicated that an optimum amount of alum existed such that good sizing retention was maintained throughout a wide range of dispersed rosin size dosages. However, when an excessive amount of alum was used and fines and colloidal particles were transitioned from anionic to cationic, the cationic size retention was reduced. Laboratory results were confirmed with a paper machine trial. All data suggested that a stock charge study was necessary to identify optimal alum dosage for a cationic dispersed rosin sizing program.

ABSTRAK Latar Belakang: Secara klinis, leukostasis didiagnosa pada pasien leukemia dengan hasil laboratorium hiperleukositosis (>100.000 u/L) disertai manifestasi respiratorik, neurologis, atau renal. Insidensi hiperleukositosis pada Leukemia Limfoblastik Akut (LLA) usia dewasa 10-30%, jarang pada wanita, dan jarang menyebabkan leukostasis. Laporan Kasus: Seorang wanita berusia 20 tahun dikonsulkan dari bagian penyakit dalam dengan kejang umum tonik-klonik. Hasil laboratorium menunjukkan leukosit 134.500 u/L, hasil EKG menunjukkan iskemik miokardium. Diskusi: Leukostasis jarang terjadi pada pasien leukemia. Leukostasis menyebabkan aliran oksigen dalam darah menuju sel menjadi inadekuat, termasuk salah satunya aliran darah yang menuju sel otak. Hipoksia jaringan otak merupakan salah satu faktor pemicu terjadinya kejang. Kesimpulan: Leukostasis merupakan suatu keadaan emergensi yang dapat meningkatkan morbiditas dan mortalitas pasien. Tujuan tatalaksana penyakit adalah mengurangi mortalitas dini, termasuk tatalaksana kejang, yang merupakan salah satu menifestasi klinis leukostasis. Kata kunci: kejang, leukostasis, leukemia. ABSTRACT Background: Clinically, leukostasis is diagnosed in patients with leukemia with laboratory results of hyperleukocytosis (> 100,000 u / L) followed by respiratory, neurological, or renal manifestations. The incidence of hyperleukocytosis in Acute Lymphoblastic Leukemia (LLA) is 10-30% of adult age, rare in women, and rarely causes leukostasis. Case Report: A 20th-years-old woman was consulted from an Internal Medicine Department with a tonic-clonic general seizure. Laboratory results showed that leukocytes were 134,500 U / L and ECG results showed an ischemic myocardium. Discussion: Leukostasis rarely occurs in leukemic patients. Leukostasis causes the flow of oxygen in the blood to the cells to be inadequate, including the blood flow to brain cells. Brain tissue hypoxia is one of the trigger factors for seizures. Conclussion: Leukostasis is an emergency situation that can increase patient morbidity and mortality. The aim of disease management is to reduce early mortality, including management of seizures, which is one of the clinical manifestations of leukostasis. Keywords: seizure, leukostasis, leukemia.

The term ‘Direct Clear Juice’ (DCJ) refers to the production of clear juice (CJ) within a modified sugarcane diffuser, thus negating the need for further juice purification in a settling clarifier. The feasibility of producing CJ by filtering treated diffuser juice through a shredded cane bed was demonstrated on a laboratory scale at the Sugar Milling Research Institute NPC (SMRI) and reported at the 2013 ISSCT congress. Factory trials were subsequently conducted at Tongaat Hulett’s Maidstone factory where the promising laboratory results were replicated in a full-scale diffuser. The production of DCJ requires consideration of the juice flow path in the diffuser, the method of lime and flocculant addition, and the screening of the juice after the diffuser. This paper summarises the results and learnings from the DCJ trials between 2011 and 2015. The development of the DCJ technology has been a collaborative project between the SMRI and Tongaat Hulett Sugar.

Concentration Of Impurities

When snow is made from sewage effluent, the impurities become concentrated in the early melt leaving the later runoff relatively pure. This could provide a low cost method of separating nutrients from secondary sewage effluent. Laboratory experiments showed that the degree of concentration was largely independent of the number of melt freeze cycles or initial concentration of impurity in the snow. The first 20% of melt removed with it 65% of the phosphorus and 90% of the nitrogen from snow made from sewage effluent; and over 90% of potassium chloride from snow made from potassium chloride solution. Field experiments with a salt solution confirmed the laboratory results.

UNSTRUCTURED The recent article published on December 23 27 in 2020 is well-written and of interest, but remains several questions that are required for clarifications, including (1) 30 feature variables with normalized format(mean=0 and SD=1) required to compare model accuracy with those with the raw-data format; (2)inconsistency in variable numbers between entry and preview panels in Figure 4 and reference typos; and (3) data-entry format with raw blood laboratory results in Figure 4 inconsistent with the model designed using normalized data to estimate parameters. We conducted a study using the training and testing data provided by the previous study. An artificial neural network(ANN) model was performed to estimate parameters and compare the model accuracy with those eight models provided by the previous study. We found that (1) normalized data yield higher accuracy than that with the raw data; (2) typos definitely exist at the bottom review (=32>30 variables in the entry) panels in Figure 4 and typos in Table 6; and (3)the ANN earns a probability of survival(=0.91) higher than that(=0.71) in the previous study using the similar entry data when the raw data are assumed in the app. We also demonstrated an author-made app using the visualization to display the prediction result, which is novel and innovative to make the result improved with a dashboard in comparison with the previous study.

Postmortem pathological examinations, animal studies, and anecdotal reports suggest that coronavirus disease 2019 (COVID-19) could potentially affect intraocular tissue. However, published evidence is scarce and conflicting. In our study, we screened 100 eyes of 50 patients hospitalized for COVID-19. Relevant medical and ophthalmological history was assessed as well as symptoms, laboratory results, specific treatments, clinical course, and outcome. Ophthalmic exams including assessment of best corrected visual acuity (BCVA), intraocular pressure (IOP), color perception, ocular motility, ophthalmoscopy as well as optical coherence tomography (OCT) of the macula and the optic disc was performed at hospital admission and 29 to 192 days later. Of the 50 patients included, 14 (28%) were female. Median age was 64.5 (range 29–90) years. COVID-19 severity was mild in 15 (30%), severe in 30 (60%), and critical in five cases (10%). At baseline, median BCVA was 0.1 (0–1.8) Logarithm of the Minimum Angle of Resolution (LogMAR) and median IOP was 16 (8–22) mmHg. At follow-up, no relevant changes in BCVA and IOP were documented. No signs of active intraocular inflammation or optic nerve affection were found and OCT findings were widely stable during the observation period. Our findings suggest that COVID-19 does not regularly affect intraocular tissue.

Critical Patients

The global severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic leading to coronavirus disease 2019 (COVID-19) is straining hospitals. Judicious resource allocation is paramount but difficult due to the unpredictable disease course. Once hospitalized, discerning which patients may progress to critical disease would be valuable for resource planning. Medical records were reviewed for consecutive hospitalized patients with COVID-19 in a large healthcare system in Texas. The main outcome was progression to critical disease within 10 days from admission. Albumin trends from admission to 7 days were analyzed using mixed-effects models, and progression to critical disease was modeled by multivariable logistic regression of laboratory results. Risk models were evaluated in an independent group. Of 153 non-critical patients, 28 (18%) progressed to critical disease. The rate of decrease in mean baseline-corrected (Δ) albumin was −0.08 g/dL/day (95% CI −0.11 to −0.04; p<0.001) or four times faster, in those who progressed compared with those who did not progress. A model of Δ albumin combined with lymphocyte percentage predicting progression to critical disease was validated in 60 separate patients (sensitivity, 0.70; specificity, 0.74). ALLY (delta albumin and lymphocyte percentage) is a simple tool to identify patients with COVID-19 at higher risk of disease progression when: (1) a 0.9 g/dL or greater albumin drop from baseline within 5 days of admission or (2) baseline lymphocyte of ≤10% is observed. The ALLY tool identified >70% of hospitalized cases that progressed to critical COVID-19 disease. We recommend prospectively tracking albumin. This is a globally applicable tool for all healthcare systems.

AbstractThere is a focus on standardisation and harmonisation of laboratory results to reduce the risk of misinterpretation of patient results assayed in different laboratories. External quality assessment (EQA) is critical to assess the need for harmonisation and to monitor the success of procedures to achieve harmonisation. However, EQA providers are being stretched to meet the needs of their participants with proven commutable material with reference method targets, a range of clinically significant levels of the materials, detailed and customised data analysis, and educational support. The path ahead for harmonisation of EQA schemes will require leadership from an organisation that has the support and confidence of EQA providers, like the European Organisation for External Qualily Assurance Providers in Laboratory Medicine.
