Color Rendering from CMYK Inks into Film Dyes
Authors: Thornton Jay , Bybell Dan , Donovan Bill , McCann John
Published: November 2022

It is often difficult to obtain quality hard copy for high resolution (eg. 6000×3000 pixels) digital images. To obtain hard copy, we use a film recorder which writes a fine image raster directly onto Polaroid instant color print film. Our concern that the color in the print be controlled as precisely as possible led to the development of a special purpose color computer. The color computer resides in the film recorder and transforms the input image pixel values into those output exposure control values necessary to attain the desired color on film. This color transformation is done on the fly without slowing down the printing of the image.
Quality Measures in Digital Halftones
Authors: Roetling Paul G.
Published: November 2022

Over about the last two decades the use of digitally generated halftone images has increased significantly. Halftone images which are created digitally from sampled and quantized images have some unique characteristics which affect the perceived image quality. Among these are the number of gray levels which can be reproduced at any spatial frequency, how the screen pattern chosen affects those gray levels, how tone reproduction is controlled and how the structured noise affects appearance. This paper provides an overview of some of the work on these effects.

Open Architecture Television
Authors: Lippman Andrew
Published: November 2022

During the past few years, potentially misdirected effort has been expended developing the notion of high definition television (HDTV) as a system akin to existing television but with approximately twice the spatial resolution horizontally and vertically, and with a slightly higher aspect ratio. System proponents have suggested “production” or distribution systems where the sole difference between current systems and these new ideas is the number of lines and the pixel rate. These efforts have resulted in international discord that may well result in a generation of television systems that impede international interchange of programs, fail to deliver higher quality to the consumer, and retard the technological convergence of computer workstation technology with that of consumer video. In this paper, we suggest that HDTV is an issue of system architecture rather than line count, and we explore signal representations that allow for multiple, simultaneous display of disparate TV standards on the same screen. The notions presented here are not fully developed but are fruitful areas of research and study. We suggest that a new generation of television systems be predicated upon sequential component representation of the video sequence rather than a series of frames and that consumer receivers and workstations be optimized for processing this video format.

Electrode surface topology enhanced KTN deflector
Authors: Liu Ruijia , Shang Annan , Lee Yun Goo , Kabir Mohammad Ahsanul , Ji Yaoyang , Yin Shizhuo
Published: November 2022

In this letter we present the first study on the electrode surface topology enhanced KTN deflector, in which one of the electrodes contains sharp edges. In this case, the electric field can be enhanced near the sharp edge. This can increase the injected charges, which in turn results in the increased deflection angle for the space charge controlled KTN deflector. Both the conducted simulations and experimental investigations agreed well. In the experiments, the sharp edge structures were created by two methods: nanofabrication and roughing with a sandpaper. Both cases experimentally obtained increased deflection ranges. This study would be beneficial to many deflector applications because it can enlarge the deflection angle without the need to increase the driving voltage.

Authors: Leshchenko Vyacheslav , Hageman Stephen J. , Cariker Coleman , Smith Gregory , Camper Antoine , Talbert Bradford K. , Agostini Pierre , Argenti Luca , DiMauro Louis F.
Published: November 2022

The Kramers–Kronig relation (KKR) has a wide range of applications in extreme ultraviolet (XUV) and x-ray spectroscopy. However, the validity of KKR for many of these applications has not been systematically studied, while it is known to require careful attention in nonlinear and pump–probe experiments in optical domain spectroscopy. Here, we study the validity of KKR in XUV attosecond transient absorption spectroscopy pump–probe measurements both experimentally and theoretically using argon Fano resonances as a case study. Experiments are enabled by a phase-resolved method dubbed Complex Attosecond Transient-absorption Spectroscopy (CATS). Although the estimations based on the rotating-wave approximation suggest that KKR violation could be expected in the studied case, our results validate KKR and provide a solid basis for its application in a broad range of attosecond spectroscopy experiments.

Authors: Silubonde Takana M. , Draper Catherine E. , Baumgartner Jeannine , Ware Lisa J. , Smuts Cornelius M. , Norris Shane A.
Published: November 2022

The prevalence of anaemia among South African women of reproductive age (WRA) remains high at 39%. Multiple micronutrient supplementation (MMS) may be an effective strategy in the prevention and management of anaemia. Our aim was to understand facilitators and barriers to preconception MMS adherence and to explore perceptions and beliefs of MMS in the prevention and treatment of anaemia among non-pregnant WRA. This qualitative study was embedded in a preconception MMS intervention trial of WRA and was conducted in two phases. Phase one assessed the barriers and facilitators of MMS adherence. Individual interviews were conducted with the community health workers (n = 7) administering MMS, and with non-pregnant WRA (n = 25) participating in the trial. Phase two included four focus groups with participating WRA (n = 26), which further explored participants’ perceptions and beliefs of MMS provision and adherence, and strategies to improve adherence. The reported facilitators to supplementation were family support, interaction with the community health workers, easy access to MMS, and experienced benefits of MMS. Barriers to preconception supplementation included the lack of family support, the link of supplements to antenatal care, and the perceived lack of benefits of MMS. Participants reported negative associations of supplements with medication, individual and societal stigma around medication and challenges around the supplementation schedule. For successful preconception MMS interventions, young women, their families, and communities need to be convinced of the value of supplementation. Public health interventions utilising preconception supplementation will require specialised training for health care providers, targeted counselling materials and community household support
Knowledge, attitudes, and practices (KAP) towards COVID-19 pandemic among pregnant women in a tertiary hospital in Karachi, Pakistan
Authors: Naz Sumaira , Dur e Shawar Syeda , Saleem Shamila , Malik Ayesha , Raza Amir
Published: November 2022

Background

The aim of this study was to evaluate the knowledge, attitude, and practices (KAP) of the pregnant population during the COVID-19 pandemic in a tertiary care hospital.

Methods

This cross-sectional study was conducted at Aga Khan University Hospital, Karachi, Pakistan. KAP towards COVID-19 was assessed using 21-item questionnaires. A score for each category was calculated and points were summed. The outcome variables of KAP were compared with demographic characteristics. Data were analyzed by using SPSS 19.

Results

A total of 377 patients participated in the study. The majority of the patients were multiparous (36.8%) in the age group of 30-40years (42.4%). More than 90% of patients were aware of COVID-19 symptoms and mode of transmission. They were aware of no cure for disease and optimum social distance. Although < 50% of patients truly answered the questions regarding the impact of COVID-19 on the risk of congenital malformation, vertical transmission, and the effect of infection on the mode of delivery. Regarding attitude and practices,> 90% of patients were anxious about fetal and personal safety, they are using a facemask, sanitizing their hands regularly, and avoiding social gatherings. Univariate and multivariable linear regression analysis showed statistically significant results among demographic variables (age, parity, family members, occupational status, and source of information).

Conclusion

Pregnant patients demonstrated inadequate knowledge regarding the impact of COVID-19 on pregnancy. However positive attitude and practices on preventive measures were good. This highlights the need for health education for pregnant women for COVID-19 to improve knowledge on a constant basis.

Published: November 2022

Introduction

As mortality rates from COVID-19 disease fall, the high prevalence of long-term sequelae (Long COVID) is becoming increasingly widespread, challenging healthcare systems globally. Traditional pathways of care for Long Term Conditions (LTCs) have tended to be managed by disease-specific specialties, an approach that has been ineffective in delivering care for patients with multi-morbidity. The multi-system nature of Long COVID and its impact on physical and psychological health demands a more effective model of holistic, integrated care. The evolution of integrated care systems (ICSs) in the UK presents an important opportunity to explore areas of mutual benefit to LTC, multi-morbidity and Long COVID care. There may be benefits in comparing and contrasting ICPs for Long COVID with ICPs for other LTCs.

Methods and analysis

This study aims to evaluate health services requirements for ICPs for Long COVID and their applicability to other LTCs including multi-morbidity and the overlap with medically not yet explained symptoms (MNYES). The study will follow a Delphi design and involve an expert panel of stakeholders including people with lived experience, as well as clinicians with expertise in Long COVID and other LTCs. Study processes will include expert panel and moderator panel meetings, surveys, and interviews. The Delphi process is part of the overall STIMULATE-ICP programme, aimed at improving integrated care for people with Long COVID.

Ethics and dissemination

Ethical approval for this Delphi study has been obtained (Research Governance Board of the University of York) as have approvals for the other STIMULATE-ICP studies. Study outcomes are likely to inform policy for ICPs across LTCs. Results will be disseminated through scientific publication, conference presentation and communications with patients and stakeholders involved in care of other LTCs and Long COVID.

Published: November 2022

Left atrial appendage (LAA) size is crucial for determining the indication of transcatheter LAA closure. The aim of this study was to evaluate the differences in LAA morphology according to the types of atrial fibrillation (AF). A total of 299 patients (mean age: 67 ± 13 years) who underwent transesophageal echocardiography (TEE) were included. Patients were classified into non-AF (n = 64), paroxysmal AF (n = 86), persistent AF (n = 87), or long-standing persistent AF (n = 62). LAA morphology, including LAA ostial diameter and depth, was assessed using TEE. Patients with long-standing persistent AF had larger LAA ostial diameter and depth and lower LAA flow velocity. The maximum LAA ostial diameter was 19 ± 4 mm in patients with non-AF, 21 ± 4 mm in patients with paroxysmal AF, 23 ± 5 mm in patients with persistent AF, and 26 ± 5 mm in patients with long-standing persistent AF. LAA ostial diameter was increased by 2 or 3 mm with the progression of AF. LAA ostial diameter was correlated with LA volume index (R = 0.37, P < 0.01) and the duration of continuous AF (R = 0.30, P < 0.01), but not with age or the period from the onset of AF. In conclusion, LAA size was increased with the progression of AF.
Does the fit of personal protective equipment affect functional performance? A systematic review across occupational domains
Authors: Brisbine Brooke R. , Radcliffe Ceridwen R. , Jones Monica L. H. , Stirling Leia , Coltman Celeste E.
Published: November 2022

Objective

To explore the effect of personal protective equipment (PPE) fit on functional performance across a range of occupational domains.

Background

PPE introduces an ergonomic, human systems integration, and mass burden to the wearer, and these factors are thought to be amplified if PPE is ill-fitting. However, few studies have considered the role of fit (static, dynamic, and cognitive) when evaluating PPE-related performance detriments in occupational settings.

Method

A systematic literature review was conducted to identify relevant studies, which were then critically appraised based on methodological quality and collated to compare key findings and present evidence-based recommendations for future research directions across a range of occupational domains.

Results

16 published studies met the inclusion criteria, 88% of which found that the fit of PPE had a statistically significant effect on occupational performance. Poorly sized PPE resulted in slower or increased reaction time; decreased range of motion or mobility; decreased endurance or tolerance; decreased pulmonary function; and altered muscle activation. Limited research met the inclusion criteria and those that did had risks of bias in methodology quality.

Conclusion

Future research evaluating the effect of PPE on performance in occupational settings should aim to recruit a more representative population; consider sex as a covariate; quantify and evaluate PPE fit and performance when integrated with all relevant equipment items; include outcome measures related to all three categories of fit (static, dynamic, cognitive); and assess performance of operationally relevant tasks.
No increased risk of cancer associated with metal-on-metal or ceramic-on-ceramic procedures compared to other bearing surfaces in patients with total hip arthroplasty: A nationwide linked registry cohort analysis of 167,837 patients
Authors: Pratt Nicole L. , Cicuttini Flavia M. , Wang Yuanyuan , Graves Stephen E.
Published: November 2022

Objectives

Studies have identified increased cancer risk among patients undergoing total hip arthroplasty (THA) compared to the general population. However, evidence of all-cause and site-specific cancer risk associated with different bearing surfaces has varied, with previous studies having short latency periods with respect to use of modern Metal-on-Metal (MoM) bearings. Using the Australian Orthopaedic Association National Joint Replacement Registry (AOANJRR) linked to Australasian Association of Cancer Registries data, our aim was to evaluate risk of all-cause and site-specific cancer according to bearing surfaces in patients undergoing THA for osteoarthritis and whether risk increased with MoM bearings.

Methods

Standardized incidence ratios (SIRs) and 95% confidence intervals (CIs) were calculated by comparing number of observed cancer cases to expected number based on incidence rate in the Australian population. All-cause and site-specific cancer rates were calculated for all conventional stemmed THA (csTHA) and resurfacing THA (rsTHA) procedures performed for osteoarthritis. Cox proportional hazards models were used to compare cancer rates for MoM, ceramic-on-ceramic (CoC) and resurfacing procedures with a comparison group comprising metal-on-polyethylene (MoP) or ceramic-on-polyethylene (CoP) procedures.

Results

There were 156,516 patients with csTHA procedures and 11,321 with rsTHA procedures for osteoarthritis performed between 1999 and 2012. Incidence of all-cause cancer was significantly higher for csTHA (SIR 1.24, 95% CI 1.22–1.26) and rsTHA (SIR 1.74, 95% CI 1.39–2.04) compared to the Australian population. For csTHA, there was no significant difference in all-site cancer rates for MoM (Hazard Ratio (HR) 1.01, 95%CI 0.96–1.07) or CoC (HR 0.98, 95%CI 0.94–1.02) compared to MoP and CoP bearings. Significantly increased risk of melanoma, non-Hodgkins lymphoma, myeloma, leukaemia, prostate, colon, bladder and kidney cancer was found for csTHA and, prostate cancer, melanoma for rsTHA procedures when compared to the Australian population, although risk was not significantly different across bearing surfaces.

Conclusions

csTHA and rsTHA procedures were associated with increased cancer incidence compared to the Australian population. However, no excess risk was observed for MoM or CoC procedures compared to other bearing surfaces.

Published: November 2022

Background

Post-acute coronary syndrome (ACS) depression is a common but not well understood complication experienced by ACS patients. Research on the effectiveness of various therapies remains limited. Hence, we sought to conduct a network meta-analysis to assess the efficacy of different interventions for post-ACS depression in improving patient outcomes.

Methods and findings

Three electronic databases were searched for randomised controlled trials describing different depression treatment modalities in post-ACS patients. Each article was screened based on inclusion criteria and relevant data were extracted. A bivariate analysis and a network meta-analysis was performed using risk ratios (RR) and standardized mean differences (SMD) for binary and continuous outcomes, respectively.

A total of 30 articles were included in our analysis. Compared to standard care, psychosocial therapy was associated with the greatest reduction in depression scores (SMD:-1.21, 95% CI: -1.81 to -0.61, p<0.001), followed by cognitive behavioural therapy (CBT) (SMD: -0.75, 95% CI: -0.99 to -0.52, p<0.001), antidepressants (SMD: -0.73, 95% CI: -1.14 to -0.31, p<0.001), and lastly, combination therapy (SMD: -0.15, 95% CI: -0.28 to -0.03, p = 0.016). No treatment modalities was found to be more effective in reducing depression scores when compared to one another. Additional analysis showed that these treatment modalities did not have significant impact on the overall mortality, cardiac mortality and recurrent myocardial infarction.

Conclusion

This network meta-analysis found that the treatment effect of the various psychological modalities on depression severity were similar. Future trials on psychological interventions assessing clinical outcomes and improvement in adherence to ACS-specific interventions are needed.

BACKGROUND

The rehabilitation intervention for upper extremity fracture varies from shoulder to finger, obtained from physical modalities and exercise. Physical modality and exercise rehabilitation intervention effectively reduce pain, increase range of motion (ROM), hand function and improve quality of life. This systematic review aims to synthesize current scientific knowledge on rehabilitative interventions with a specific focus on upper extremity fractures and the effect of all interventions on the patient.

METHODS

Three scholarly databases (PubMed, Google Scholar, Science Direct) were systematically searched. Literature published before 10 January 2022 focused on upper extremity fracture and rehabilitation treatment patients. Quality assessment was completed with CEBM tools by Oxford University. For PICO, The Population was upper extremity fractures, and the intervention was rehabilitation intervention, both physical modality and exercise. The comparation was other rehabilitation interventions or without rehabilitation, and the outcome in this study were measured with the visual analogue scale (VAS), ROM, hand function, and quality of life (QoL).

RESULTS

Eight studies were included in this review among 18.326 reference titles founded and screened. All of the studies had various sample sizes followed by bias analysis with CEBM tools. Rehabilitation for elbow fracture was dynamic fixation using rigid tape and proprioceptive neuromuscular facilitation stretching. Rehabilitation for distal radius fracture was scapular exercise, graded motor imagery, hot pack on hand volume, illusory kinesthesia, and wrist exercise. These interventions can reduce the pain, improve strength, range of motion, hand function and quality of life in upper extremity fracture patients.

CONCLUSIONS

Exercise and physical modality rehabilitation intervention have proven to reduce pain, improve strength, range of motion, hand function and quality of life in upper extremity fracture patients.

Anthropogenic activities like damming, channel modification, water abstraction, sewage and effluent disposal, sand mining, unthoughtful exploitation of biotic resources, etc. are the major threats faced by the rivers in the country. Monitoring protocol of Indian rivers lacks an integrated approach based on judicious use of both abiotic and biotic components as well as a total lack of consideration for ecological health. Index of Biotic Integrity is a flexible multimetric index that can be modified and adapted to the various zoogeographic regions of the world. A fish-based multi-metric IBI was developed by modifying and incorporating metrics that are sensitive to the various ecological stressors faced by Indian rivers, fishes being excellent indicators of river health. The adapted IBI was validated and used to assess ecological health of two rivers—Mahanadi, and its distributary Kathajodi-Devi—flowing through central-eastern India. The study indicated that in River Mahanadi, around 25% of the freshwater river stretch was slightly impaired and the remaining 75% stretch was moderately impaired. In Kathajodi-Devi, most of the river stretches were in a moderately impaired condition, except at Italnga stretch where the river was severely impaired. The Index of Biotic Integrity scores estimated could reflect the ecological health of the rivers. The study shows that use of Index of Biotic Integrity is a useful and reliable approach to assess the health conditions of Indian aquatic resources warranting initiatives to be taken to implement and incorporate it into the country's water resource management.

The Tamas River is a right-bank tributary of the River Ganga, originating from Jhukehi village in Madhya Pradesh and meeting up with the Ganga at Sirsa, Prayagraj, Uttar Pradesh, India. An investigation was carried out in six sites at (Itahara, S1), (Madhavgarh, S2), (Bakiya upstream, S3), (Bakiya downstream, S4), (Chakghat, S5) and (Panasaghat, S6) of the river to document the fish diversity, seasonal variability, and impact of environmental variables on fish species composition during the period 2017 to 2019. Altogether 75 fish species belonging to 54 genera, 23 families, and 10 orders were recorded. Fish species richness at (S1), (S2), (S3), (S4), (S5), and (S6) and was recorded as 9, 39, 38, 13, 61, and 49, respectively. Family Cyprinidae with 31 species contributing 41% was the most dominant family, followed by Bagridae (8%) and Schilbeidae (6.7%). Seasonal variation in fish species richness and diversity indices were observed in the river stretch. Maximum species richness (45) was observed at S5 during monsoon and a minimum (6) at S1 during post-monsoon. As per the International Union for Conservation of Nature categorization, 10 out of 75 fish species recorded from the river were considered to be threatened. Three exotic species, namely Cyprinus carpio, Oreochromis niloticus, and Hypophthalmichthys nobilis, were recorded at some stretches, which may be a concern for native fish diversity. Environmental variables like water temperature, pH, dissolved oxygen, water velocity, and alkalinity influenced the fish community structure. The selected (S1–S6) stretch of the river falls under the category of Slightly Impacted River based on the Shannon Index (H’ >3). The present investigation was the first assessment of rich fish diversity covering the maximum stretch of river, which supports many important and small indigenous fishes for conservation.

The River Tamas is a right-bank tributary of the River Ganga flowing through the states of Madhya Pradesh and Uttar Pradesh, India. It originates in Jhukehi village in the Satna district of Madhya Pradesh and after 268 km it joins with the River Ganga at Sirsa, Prayagraj, Uttar Pradesh. The river has a diverse habitat and harbours a variety of flora and fauna. More than 70 fish species reside in the river, along with other biotic communities. A barrage, named Tons and situated at Bakiya village, was commissioned in 1992 for hydro-electric purposes. The continuity and volume of water in the river have been disturbed due to the construction of this barrage and it has changed the ecology and biodiversity. Keeping the ecosystem intact requires that environmental flow calculations be made of the river at the barrage. An attempt has been made to estimate the environmental flow requirement using a desktop hydrological method. Based on the flow duration curve (a hydrological method of flow estimation), the environmental flow for the River Tamas has been calculated using Global Environmental Flow Calculator software. Our calculation are based on flow discharge data received from the Tons Barrage Authority at Bakiya for the period January 2006 to December 2017. Average annual discharge was calculated from the recorded maximum (151.46 cumecs in 2016) and the minimum, 13.53 cumecs in 2007. Mean Annual Runoff was calculated as 1607 Million Cubic Meter with Coefficient of Variation =0.799. To maintain the river in the “slightly modified” class of Environmental Management Class, 27.8 % of Mean Annual Runoff discharge should be released into the river to largely maintain the biodiversity and habitat, while about 57% of Mean Annual Runoff discharge is required to maintain this river in pristine condition. This is a preliminary study to determine the water requirements for healthy habitat and biodiversity of the Tamas river.
Hora da brinquedoteca: o jogo de papéis em foco
Authors: Moraes Marcela Cristina de
Published: November 2022

Este artigo é parte de pesquisa de doutorado e discute as atividades de crianças de 3 a 5 anos, desenvolvidas na brinquedoteca de uma escola de Educação Infantil, focalizando nos jogos de papéis sociais, fundamentada na teoria Histórico-Cultural. O objetivo foi observar se as crianças realizam jogos de papéis nas interações na brinquedoteca. Os resultados indicaram apego das crianças aos brinquedos/objetos, dificultando o avanço dos jogos de papéis, visto que gastam muito tempo com os conflitos. A turma de 5 anos apresentou aumento quantitativo de jogo de papéis sociais em relação à turma de 3 anos, porém essa diferença não significou avanço qualitativo, uma vez que a variedade de papéis sociais foi pequena; as ações tiveram pouca variação, bem como, os temas e os diálogos foram pontuais e exíguos. Não observamos a iniciativa, independência e cumprimento de objetivos nas crianças. Assim, sem a intervenção da professora, as crianças desenvolvem jogo de papéis sociais num formato simplificado, indicando a necessidade de uma intervenção planejada na zona de desenvolvimento proximal das crianças, auxiliando-as a selecionar e vivenciar temas em suas relações com brinquedos e outros objetos.

Atualmente, a maioria das prefeituras que iniciaram o processo de implantação de um SIG utiliza dois tipos de banco de dados: um para o sistema cadastral e outro para o SIG. Dessa maneira, perde-se muito tempo com o que se refere à atualização do banco de dados de ambos os sistemas. Sendo assim, geralmente prioriza-se o banco de dados do sistema cadastral, uma vez que o município precisa de arrecadação para se manter. Manipular tais dados para diversos fins, dentro de um banco de dados único é de extrema eficácia, pois os dados podem ser atualizados mais facilmente, além de não possuírem duplicidade. O presente trabalho mostra um conjunto de aplicativos, que tem por principal objetivo a integração do banco de dados cadastral, implantado para fins de cálculo de IPTU e outras taxas com um banco de dados

relacional, que pode ser utilizado para análises em planejamento estratégico. A importância desse trabalho reside no fato da possibilidade de disponibilização de informações sistematizadas com maior eficiência e menor custo. Além disso, a metodologia desenvolvida proporcionará melhores condições para a atualização cadastral em menores períodos

de tempo pois, através da leitura óptica dos boletins de informações cadastrais, o custo será reduzido naturalmente, viabilizando a operação. Podendo, as informações cadastrais, ser atualizadas em curtos períodos de tempo, aumenta-se a confiabilidade no sistema, proporcionando-se mais segurança para a disponibilização de informações com acesso

remoto, além do oferecimento de serviços via Internet.
THE CAPACITY OF THE SCINTREX AUTOGRAV CG-3M NO. 4492 GRAVIMETER FOR "ABSOLUTE-SCALE" SURVEYS
Authors: Timmen Ludger , Gitlein Olga
Published: November 2022

In autumn 2001, the Institut fÃ¼r Erdmessung (IfE), received the new Scintrex Autograv CG-3M spring gravimeter no. 4492 (SC-4492). Compared with LaCoste-Romberg gravimeters, the Scintrex instrument offers the advantage of a more simple calibration function. Due to the straightforward sensor design (no micrometer screws and gearboxes, no astatisation), a modelling of periodical calibration terms and of a higher order polynomial calibration function is not required. The costly calibration measurements can be reduced to some relative observations between two reliable absolute gravity stations. No complex calibration system should be necessary. A reliable evaluation of the SC-4492 was done with respect to the stability of the calibration, measurement accuracy and precision, drift behaviour, and gravity range dependency of the calibration factor. Measurements were performed on the Hannover vertical calibration line (200 Î¼m/s2 (20 mGal) range, 20-storied building, 10 Î¼m/s2 interval), on the Cuxhaven-Harz north-south line (3000 Î¼m/s2 range, 34 stations, 90 Î¼m/s2 interval) of the gravimeter calibration system Hannover, and in the absolute gravimetry net of the Fennoscandian land uplift area (6200 Î¼m/s2 range). A total gravity range of almost 0.015 m/s2 has been covered. In addition, the gravimeter was employed in the determination of vertical gravity gradients and centring to safety points for absolute gravimetry, and the observation of the horizontal gradient field at the IfE absolute gravity reference station in Clausthal. This paper presents the results as obtained in regional, local and microgravimetric surveys. The achieved accuracies are in the order of Â±10 to 100 nm/s2 (Â±1 to 10 Î¼Gal). No instability of the calibration and no gravity range dependency could be proven within the order of 1Â·10-4. Overall, the gravity meter SC-4492 meets fully the expectations of IfE.
