AbstractOver the past decades, the development of fibre optic cables, which pass light waves carrying data guided by total internal reflection, has led to advances in high-speed and long-distance communication, large data transmission, optical imaging, and sensing applications. Thus far, fibre optic sensors (FOSs) have primarily been employed in engineering, biomedicine, and basic sciences, with few reports of their usage in geophysics as point and distributed sensors. This work aimed at reviewing the studies on the use of FOSs in geophysical applications with their fundamental principles and technological improvements. FOSs based on Rayleigh, Brillouin, and Raman scatterings and fibre Bragg grating sensors are reviewed based on their sensing performance comprising sensing range, spatial resolution, and measurement parameters. The recent progress in applying distributed FOSs to detect acoustic, temperature, pressure, and strain changes, as either single or multiple parameters simultaneously on surface and borehole survey environments with their cable deployment techniques, has been systematically reviewed. Despite the development of fibre optic sensor technology and corresponding experimental reports of applications in geophysics, there have not been attempts to summarise and synthesise fibre optic methods for prospecting as a comprehensive and modern branch of geophysics. Therefore, this paper outlines the fibre optic prospecting methods, with an emphasis on their advantages, as a guide for the geophysical community. The potential of the new outlined fibre optic prospecting methods to revolutionise conventional geophysical approaches is discussed. Finally, the future challenges and limitations of the new prospecting methods for geophysical applications are elucidated.

The Lushi gold polymetallic ore-concentration area, located in the southern margin of North China Craton, is an important polymetallic ore district in the Qinling metallogenic belt. The Jianbeigou gold deposit is an important quartz vein type gold deposit in this district. In order to reveal the geological structure of the Jianbeigou gold deposit to guide deep prospecting, the EH4 conductivity image system was used in the Jianbeigou area. The sections obtained by the audio magnetotellurics method (AMT) indicate that the steeply dipping low resistivity zone in the area has a good corresponding relationship with the location of the known shallow ore bodies, and an extension in the deep. The low resistivity anomaly zone obtained by the inversion results are well correlated with the gold mineralization zone of the ore bodies, indicating good deep prospecting and exploration potential in this area. Based on geological and geophysical evidences, this paper inferred the possible occurrence location and depth range of the buried ore bodies. The AMT survey results reflect good exploration potential of the mining area and provide a geophysical basis for deep prospecting.

This study aimed to understand the social environment of groundnut production in Burkina Faso. The prospecting was carried out in three regions of Burkina Faso, namely the Central-East, the Central-North, and the Central-West Regions. Data were collected through direct observations and individual interviews using a questionnaire guide. At the end of this study, five (05) local ecotypes were collected which varied according to the ethnic group. These were Mayoro, zampou, dalga in Bissa ethnic group and Balolé, Wobgo in Mooré ethnic group. It appeared that groundnuts are mainly grown by women in small areas and these local ecotypes are disappearing progressively in favour of improved varieties developed by INERA (SH470P, QH243C). Research efforts for an agro-morphological and molecular genetic characterization of local varieties are necessary to facilitate their conservation.

The Hetaoping ore district in Baoshan City, Yunnan Province, is one of the major localities of Pb-Zn polymetallic skarn deposits in China, where geophysical and geochemical surveys play an important role in exploring Pb-Zn polymetallic mineral resources. Based on the exploration and prospecting carried out at the periphery of the Hetaoping Pb-Zn polymetallic deposit, this study proposed an aero-ground joint exploration method to determine the metallogenic model of distal skarns in the Hetaoping ore district, achieving ideal prospecting results. The steps of this method are as follows. First, the locations of ore-induced anomalies were determined using high-amplitude aeromagnetic anomalies. Then, the ore-induced anomalies were determined to be anomalies of Pb-Zn polymetallic deposits through geochemical surveys of soil samples and ground geophysical surveys. Based on these data, a quantitative analysis and metallogenic potential assessment of ore bodies and their surrounding rocks were conducted using the interactive 2.5D magnetic inversion. In addition, the 3D inversion of regional gravity data was also performed in order to determine the spatial location of the deep magma chamber. Accordingly, the metallogenic geological process in this area was analyzed by determining the spatial morphology of the deep magma chamber, and a prospecting model of the Pb-Zn polymetallic deposits was finally built. The results show that the aero-ground joint exploration method, which first conducts a rapid scanning survey using the aeromagnetic method and then locates, distinguishes, and assesses significant aeromagnetic anomalies by combining comprehensive verification means such as ground geophysical, geochemical, and geological surveys, is efficient and economical. This study will guide regional metallogenic research and the exploration and prospecting of Pb-Zn polymetallic deposits.

ABSTRACT. Multisource spatial data integration represents a common tool in mineral prospecting, especially with the advent of Geographic Information Systems(GIS), which allow manipulation, interpretation, analysis, integration and modelling of spatial data. The Nova Brasilˆandia Metasedimentary Belt (NBMB), located in SWAmazonian craton, is part of a geological context with considerable metallogenic potential for base metals, although significant deposits are not known yet. The presentpaper aimed to process aeromagnetometry and aerogammaspectrometry data for integration with geochemical and geological mapping campaigns in order to build aprospectivity model for nickel in the NBMB region of in a 1:500,000 scale. Using knowledge-driven approach modelling, fuzzy logic was chosen to combine geophysics,geochemistry and geological mapping data. As result, it was possible to build a prospectivity model for nickel, consistent with the distribution of nickel occurrencesregistered by the Geological Survey of Brazil (Servic¸o Geol´ogico do Brasil – CPRM), and witch may guide detailed prospecting campaigns in the region.Keywords: airborne geophysics, fuzzy logic, prospective modelling, metasedimentary belt, Nova Brasilândia.RESUMO.

Subway tunnel construction plays a significant role in the development of urban underground space. Advance surface grouting treatment of adverse subsurface geological bodies is an effective measure to avoid the accidents during subway construction. This paper describes the successful application of geological prospecting and grouting assessment at the tunnel site of Qingdao subway line No. 1. The study area is located in a coastal bedrock fissure water distribution area. It was decided to conduct surface grouting to reduce the high risk of water inrush. Integrated investigation consisting of electrical resistivity tomography (ERT), seismic ahead prospecting, surface vertical drilling and cross-hole ERT was conducted to ascertain the geological conditions and guide the grouting scheme design. Surface ERT and seismic ahead prospecting were adopted to provide a rough survey of water bearing conditions and fractured zones. Then, detailed imaging was conducted using cross-hole ERT inversion with the inequality constraint based on the information obtained using surface vertical drilling. The shape and location of three water bearing structures were identified. Based on the integrated investigation results, an appropriate grouting scheme was designed. After the application of grouting, cross-hole ERT was carried out again to assess the effect of grouting by comparing the vibration of twice inversion results of cross-hole ERT and resistivity tests of the grout sample. Such information serves as a basis for guiding geotechnical excavations in complex urban environments and avoids the risk of construction accidents.

Sugar cane bagasse flour (Saccharum officinarum L.) is a promising product and has great market potential with application in human food. With the help of technological and scientific prospecting, it is possible to guide and cover the view on research about the use of this material in the area of food science. With that, the objective was to investigate the existence of the development of sugarcane bagasse flour in technological and scientific databases. The patent bases analyzed were the National Institute of Industrial Property (NIIP), the World Intellectual Property Organization (WIPO), the United States Patent and Trademark Office (USPTO) and the Espacenet Patent Search database. The scientific platforms analyzed were Scientific Electronic Library Online (SciELO), Web of Science, Pubmed and Portal Periódicos Capes (Brazil). Brazil has made progress in intellectual production on patent bases, however, no technological and / or scientific record has been identified regarding the use of flour for human consumption in the analyzed period. From this, it is necessary, then, to carry out research on the food potential of this flour, mainly in Brazil, since the country is considered the largest producer of sugarcane, having a vast material to be explored, developing functionality in the development of new products and increasing intellectual property in the area.

Dachang ore field is located in the central of Au, Sb, Hg metallogenic belt in the north Bayankela mountain, with the Maduo - Gande deep major fault as its regional guide mineral structure. The gold deposits have grew up in the fracture - fissure system of large share zone in BaYanKaLa mountain group of Triassic strata, and Magmatic activities in Yanshan Period provides favorable conditions for the activation, migration, enrichment and mineralization of gold element. Geophysical - geochemical anomaly and remote sensing of this area have shown that they are related with the mineralization, that means abnormal area with bigger Intensity is often located in the cross area of tectonic alteration and mineralization. Triassic strata, the north - west fault and its secondary structure - rock system and geophysical - geochemical anomaly are the obvious symbols of gold prospecting in the area. Through the metallogenic regularity, obvious symbols and distincting some geophysical - geochemical anomalies, more large and medium-sized gold deposits have been found. We should along the Maduo - Gande fault zone, extending for east - west trend and the depth, and larger scale gold deposits is expected to be found.

Percussion drilling has been widely used in oil and gas industry, yet it still has some shortcomings, such as severe damages to drilling tools, low energy transferring efficiency and low rock-fragmenting efficiency. Thus it is necessary to reveal the mechanism of interactions between the hammer bit and rock in geophysical prospecting percussion drilling. Taking account of the coupling effect of the Weight on Bit (WOB), impact force and rotary torque, this paper constructed a Finite Element Method (FEM) model using the finite element analysis software (ANSYS/LS-DYNA) and conducted a computer simulation of bit-rock interaction under rotating and simple impact effect, which showed the rock-fragmenting process of hammer bit and the curves of volume-time and depth-time of craters as well as the effective stress-time curves of the centre tooth, second-row tooth and peripheral tooth. The results showed that: the percussion drilling process under rotating impact effect is characterized as four fundamental processes; the crater depth mainly depends on impact force rather than rotary torque; the crater created under rotating impact effect is twice the volume of that under impact effect; the effective stress of each tooth changes severely: the stress of second-row tooth is the largest, centre tooth the second, and peripheral tooth the smallest. This study provided a guide for the structural optimization of hammer bit and general applications of percussion drilling.

Geothermal energy is part of the renewable energy mix. It is used for heating, air conditioning and sometimes even for the production of electricity. Prospecting for such a resource proves to be a difficult and capital-intensive task. To overcome this constraint, we have used remote sensing which is an adequate tool to guide the prospecting through the elaboration of hydrothermal resource potential maps at the level of zones that present a favorable potential for exploitation (hyper-tectonized sites, volcanic sites, faulted sites, sites with hot geological formations, seismic zones...). The objective of this work is to carry out a study on the North-East of Morocco (Berkane Province), in order to identify favorable sites for geothermal exploitation such as geologically and hydrogeologically active sites. The methodology adopted consists in processing the images of the OLI (Operational Land Imager) and TIRS (Thermal Infrared Sensor) sensors of the Landsat-8 satellite in order to extract spectral indices (Clay mineral Index and Ferrous mineral Index,) detecting a geothermal activity and the surface temperature map (LST) using muticriteria analysis method (MCA). ) in the north-eastern part of Morocco. The results obtained show an almost perfect concordance of the distribution of the above-mentioned indices, with the map of lineaments which are considered as heat drains from the depth to the surface. Moreover, a correct correlation was established during the validation of these results with the map of the inventory of hydrothermal springs identified in the study area.

The Dayaoshan, which has nearly 200 gold deposits (or mineralization points), is one of the most important gold deposits distribution areas in Guangxi, and the Gupao gold deposit is an important representative one. Previous researches have carried out numerous works there to guide the gold prospecting work. Due to multiple episodes of gold mineralization and multiple sources materials in ore-forming, there are heated debates on the era of the mine, and the main mineralization age of the Gupao gold deposit is focused on the Caledonian or Early Yanshanian. According to the distribution characteristics of the gold ore body showing in the Zhilong, Gulinao, and Dawangding gold deposit, the discussion of macro-tectonic setting of the area, as well as the comparative study of surrounding gold deposits, we conclude that the main mineralization age of the Dawangding gold deposit is Early Yanshanian, and the main mineralization may be controlled by the nearly east-west trending fold which was caused by the north-south extrusion.

The Mid-Atlantic Ridge belongs to slow-spreading ridges. Hannington predicted that there were a large number of mineral resources on slow-spreading ridges; however, seafloor massive sulfide deposits usually develop thousands of meters below the seafloor, which make them extremely difficult to explore. Therefore, it is necessary to use mineral prospectivity mapping to narrow the exploration scope and improve exploration efficiency. Recently, Fang and Shao conducted mineral prospectivity mapping of seafloor massive sulfide on the northern Mid-Atlantic Ridge, but the mineral prospectivity mapping of magmatic-related seafloor massive sulfide on the whole Mid-Atlantic Ridge scale has not yet been carried out. In this study, 11 types of data on magmatic-related seafloor massive sulfide mineralization were collected on the Mid-Atlantic Ridge, namely water depth, slope, oceanic crust thickness, large faults, small faults, ridge, bedrock age, spreading rate, Bouguer gravity, and magnetic and seismic point density. Then, the favorable information was extracted from these data to establish 11 predictive maps and to create a mineral potential model. Finally, the weights-of-evidence method was applied to conduct mineral prospectivity mapping. Weight values indicate that oceanic crust thickness, large faults, and spreading rate are the most important prospecting criteria in the study area, which correspond with important ore-controlling factors of magmatic-related seafloor massive sulfide on slow-spreading ridges. This illustrates that the Mid-Atlantic Ridge is a typical slow-spreading ridge, and the mineral potential model presented in this study can also be used on other typical slow-spreading ridges. Seven zones with high posterior probabilities but without known hydrothermal fields were delineated as prospecting targets. The results are helpful for narrowing the exploration scope on the Mid-Atlantic Ridge and can guide the investigation of seafloor massive sulfide resources efficiently.

Single-channel and multi-channel seismic exploration have become two important geophysical methods in offshore engineering geological investigation. Both of the two methods can present high sensitivity and high resolution information about the strata under the seafloor. However, the single-channel seismic prospecting method has some limitations in high resolution engineering surveys. For example, (1) When the depth of water is relatively shallow, the system cannot get zero offset profile; (2) The reflective events will be distorted if the terrain of the seafloor is complex, and thus make the interpretation much more difficult; (3) We cannot remove the influence of the complex multiples in single-channel seismic data processing; (4) We cannot get the lithological and physical properties directly using single-channel seismic method; and, (5) The spatial resolution of single-channel is also lower than that of multi-channel seismic method. In this paper, we presented some examples, and the above problems have been discussed to compare the two methods. All those can give a good guide for selecting appropriate exploration methods.

Multiband space remote sensing is an indirect tool for prospecting the Earth's surface. It is very powerful especially in its applications related to the field of geology including geological mapping, mining and oil exploration. It can also significantly reduce the cost of exploration, reach inaccessible areas, guide mining research to favorable regions and reach a large surface. In this article, we highlight in details the state of knowledge in this field of research by citing the different methods and approaches carried out by several specialists who generally define the use of remote sensing for lithostructural and mineralogical mapping and particularly for the exploration and research of mineral substances. We also create methods derived from the aforementioned methods of treatment by means of a logical analogy between the different bands of several satellites of observation of the terrestrial globe, particularly between : Landsat 7 ETM +; Landsat 8 OLI / TIRS; Aster and Sentinel 2A. At the end, we synthesize these results by proposing a multispectral image-processing model that can be applied directly. This model starts with the calculation of Optimum Index Factor (OIF), which allows us to detect only the most important colored composites; and the reports of the bands, rations, the principal component analysis, ACI and the classification that allow the realization of a lithological and mineralogical mapping as well as maps of lineaments by means of directional filters. The validity of the models is tested by comparison with field data and geological maps of the studied site.

The Axi low-sulfidation (LS) epithermal deposit in northwestern China is the result of geological controls on hydrothermal fluid flow through strike-slip faults. Such controls occur commonly in LS epithermal deposits worldwide, but unfortunately, these have not been quantitatively analyzed to determine their spatial relationships with gold distribution and further guide mineral prospecting. In this study, we conduct a 3D mineral prospectivity modeling approach for the Axi deposit involving 3D geological modeling, 3D spatial analysis, and prospectivity modeling. The spatial analysis of geometric features revealed the gold mineralization trends in convex segments (0–20 m) with a specific distance from fault 2, the lower interface of late volcanic phase, and the upper interface of phyllic alteration with steep slopes (>65°), implying that gold deposition was significantly controlled by the morphological characteristics and distance fields of geologic features. The present alteration–mineralization zone at Axi has a larger width in bending sites (sections No. 35–15 and No. 40–56) than elsewhere, indicating the location of two fluid conduits extending to depth. The prediction-area plots and receiver operating characteristic curves demonstrated that (genetic algorithm optimized support vector regression (GA-SVR)) outperformed multiple nonlinear regression and fuzzy weights-of-evidence, which was proposed as a robust method to solve complicated nonlinear and high-dimensional issues in prospectivity modeling. Our study manifests spatial controls of structure, host rock, and alteration on LS epithermal gold deposition, and highlights the capability of GA-SVR for identifying deposit-scale potential epithermal gold mineralization.

Abstract Objectives To evaluate the accuracy and reliability of dental MRI for static guided implant surgery planning. Materials and methods In this prospective study, a 0.4-mm isotropic, artifact-suppressed, 3T MRI protocol was used for implant planning and surgical guide production in participants in need of dental implants. Two dentists decided on treatment plan. Surgical guides were placed intraorally during a subsequent reference cone beam computed tomography (CBCT) scan. Inter-rater and inter-modality agreement were assessed by Cohen’s kappa. For each participant, dental MRI and CBCT datasets were co-registered to determine three-dimensional and angular deviations between planned and surgically guided implant positions. Results Forty-five implants among 30 study participants were planned and evaluated (17 women, 13 men, mean age 56.9 ± 13.1 years). Inter-rater agreement (mean κ 0.814; range 0.704–0.927) and inter-modality agreement (mean κ 0.879; range 0.782–0.901) were both excellent for the dental MRI-based treatment plans. Mean three-dimensional deviations were 1.1 ± 0.7 (entry point) and 1.3 ± 0.7 mm (apex). Mean angular deviation was 2.4 ± 1.5°. CBCT-based adjustments of MRI plans were necessary for implant position in 29.5% and for implant axis in 6.8% of all implant sites. Changes were larger in the group with shortened dental arches compared with those for tooth gaps. Except for one implant site, all guides were suitable for clinical use. Conclusion This feasibility study indicates that dental MRI is reliable and sufficiently accurate for surgical guide production. Nevertheless, more studies are needed to increase its accuracy before it can be used for implant planning outside clinical trials. Key Points • An excellent reliability for the dental MRI-based treatment plans as well as agreement between dental MRI-based and CBCT-based (reference standard) decisions were noted. • Ideal implant position was not reached in all cases by dental MRI plans. • For all but one implant site surgical guides derived from dental MRI were sufficiently accurate to perform implant placement (mean three-dimensional deviations were 1.1 ± 0.7 (entry point) and 1.3 ± 0.7 mm (apex); mean angular deviation was 2.4 ± 1.5°).

<abstract> <p>The collapse is the most frequent and harmful geological hazard during the construction of the shallow buried tunnel, which seriously threatens the life and property safety of construction personnel. To realize the process control of collapse in the tunnel construction, a three-stage risk evaluation method of collapse in the whole construction process of shallow tunnels was put forward. Firstly, according to the engineering geology and hydrogeology information obtained in the prospecting stage, a fuzzy model of preliminary risk evaluation based on disaster-pregnant environment factors was proposed to provide a reference for the optimization design of construction and support schemes in the design stage. Secondly, the disaster-pregnant environment factors were corrected based on the obtained information, such as advanced geological forecast and geological sketch, and the disaster-causing factors were introduced. An extension theory model of secondary risk evaluation was established to guide the reasonable excavation and primary support schemes. Finally, the disaster-pregnant and disaster-causing factors were corrected according to the excavation condition, an attribute model of final risk evaluation for the collapse was constructed combined with the mechanical response index of the surrounding rock. Meanwhile, the risk acceptance criteria and construction decision-making method of the collapse in the shallow buried tunnels were formulated to efficiently implement the multi-level risk control of this hazard. The proposed method has been successfully applied to the Huangjiazhuang tunnel of the South Shandong High-Speed Railway. The comparison showed that the evaluation results are highly consistent for these practical situations, which verify the application value of this study for guiding the safe construction of shallow buried tunnels.</p> </abstract>

The accuracy of static guided implant surgery (sGIS) using conventional planning workflow has been extensively examined; however, more information is required to justify the application of fully digital planning protocol. The purpose of this study was to investigate the clinical accuracy of sGIS with a fully digital planning workflow. Twenty-one partially edentulous patients were enrolled in this prospective study. Cone-beam computed tomography (CBCT) and intraoral scans were taken and superimposed by matching the dental surface images directly (surface registration protocol) or by matching fiducial markers on a stereolithographic (SLA) radiographic template fabricated from the digital data of the intraoral scan (fiducial marker registration protocol). Virtual implant treatment plans were then determined, and tooth-supported SLA surgical guides were fabricated according to the plans. Twenty-six implant surgeries were performed via the surgical guide by one surgeon. Pre- and post-operative CBCT images were superimposed, and the positional and angular deviations between placed and planned implants were measured with metrology software. A total of 43 fully guided implants were placed, in which 25 implants were planned with the surface registration protocol. Implants planned based on the surface registration protocol had a larger mean angular deviation than the fiducial marker registration protocol. No significant differences were found for any deviations of the examined variables. Within the limits of this study, we concluded that the clinical accuracy of the sGIS planned with a fully digital workflow was consistent with the conventional workflow for partially edentulous patients.

Abstract Background and study aims Colonoscopy can be technically challenging and cause discomfort in patients. The integrated Scope Guide assist is built in to show that with its use outcomes are improved during colonoscopy. We aimed to test the usefulness of the Magnetic Scope Guide Assist (ScopeGuide) with respect to cecal intubation time, and other procedural quality outcomes. Patients and methods We conducted a prospective study of outpatients undergoing elective colonoscopy at the endoscopic units of the University of Alabama at Birmingham (UAB) from March 2016 to July 2016. Patients were randomly assigned in a 1:1 block design to groups that either had standard colonoscopy or Scope-guided colonoscopy. The primary outcome measure was cecal intubation time (CIT). Secondary outcome measures included use of manual pressure, position changes for cecal intubation and sedation requirements. Results Three hundred patients were randomized to either group; standard (n = 150) vs. Scope-guided (n = 150). The mean CIT was not statistically different for the standard and the Scope-guided groups (4.6 vs. 4.3 minutes; P = 0.46). There were also no statistical differences in frequency of manual pressure applied (16.7 % for Scope-guided vs. 19.1 % for standard; P = 0.65) or position changes (11.4 % for scope guided vs. 8.8 % standard; P = 0.56). Sedation requirements showed lesser use of midazolam (3.9 mg vs. 4.7 mg, P = 0.003) in the Scope-guide group, while there was no significant difference in use of fentanyl (fentanyl – 62.1 mg vs. 68.9 mg, P = 0.09 similar between groups, for Scope-guided vs. standard groups, respectively). Adverse events were similar in both groups. Conclusions In patients undergoing routine elective colonoscopy, use of ScopeGuide by experienced colonoscopists did not improve CIT or affect the frequency of ancillary maneuvers. The benefit of this device during training of endoscopists could be considered for further studies.

With mining of seafloor massive sulfides (SMS) coming closer to reality, it is vital that we have a good understanding of the geochemistry of these occurrences and the potential toxicity impact associated with mining them. In this study, SMS samples from seven hydrothermal fields from various tectonic settings were investigated by in-situ microanalysis (electron microprobe (EMPA) and laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS)) to highlight the distribution of potentially-toxic trace elements (Cu, Zn, Pb, Mn, Cd, As, Sb, Co, Ni, Bi, Ag and Hg) within the deposits, their minerals and textures. We demonstrate that a combination of mineralogy, trace element composition and texture characterisation of SMS from various geotectonic settings, when considered along with our current knowledge of oxidation rates and galvanic coupling, can be used to predict potential toxicity of deposit types and individual samples and highlight which may be of environmental concern. Although we cannot quantify toxicity, we observe that arc-related sulfide deposits have a high potential toxicity when compared with deposits from other tectonic settings based on their genetic association of a wide range of potentially toxic metals (As, Sb, Pb, Hg, Ag and Bi) that are incorporated into more reactive sulfosalts, galena and Fe-rich sphalerite. Thus, deposits such as these require special care when considered as mining targets. In contrast, the exclusive concern of ultra-mafic deposits is Cu, present in abundant, albeit less reactive chalcopyrite, but largely barren of other metals such as As, Pb, Sb, Cd and Hg. Whilst geological setting does dictate metal endowment, ultimately mineralogy is the largest control of trace element distribution and subsequent potential toxicity. Deposits containing abundant pyrrhotite (high-temperature deposits) and Fe-rich sphalerite (ubiquitous to all SMS deposits) as well as deposits with abundant colloform textures also pose a higher risk. This type of study can be combined with “bulk lethal toxicity” assessments and used throughout the stages of a mining project to help guide prospecting and legislation, focus exploitation and minimise environmental impact.

A simple approximate representation of the spectral response of an arbitrary kind of electromagnetic (EM) prospecting system to a small conductive target in a conductive environment has been derived. The representation contains the direct response from the layered host medium and the first‐order effects of eddy current induction, current channeling, magnetic induction, and the coupling between eddy current and magnetic inductions in the anomalous body, as modified by the host medium. The only significant computational task in the representation is evaluation of a few Green’s functions for the host medium. As a guide to establishing proper approximations, a fundamental study of integral equations is presented. Very simple solutions for the secondary or scattering sources which represent the EM effect of the body are obtained for a few basic cases. Equations for more general cases are complicated by additional terms in the Green’s functions which represent ac interaction between scattering sources and the host medium, the effects of layering in the host, or interactions between the different types of scattering sources. Through a supplementary study of the response of a conductive disk embedded in a conductive host to an axisymmetric field, the ac interaction between the host medium and scattering sources in the disk is shown to be relatively unimportant. Hence, interaction with layering in the host is also minimal. Green’s functions in the integral equation can consequently be simplified. The representation as a whole has been tested by comparing its predictions of the spectral form of a response with two published data sets, responses of a plate model in a conductive host. The fits for targets of moderate and large size, relative to the scale of the particular experiment, range from excellent to good qualitative resemblance. The representation should find application in making expensive numerical or analog model studies more useful and understandable to the field geophysicist, in converting real and model data between the time‐ and frequency‐domain formats, in constructing practical inverse algorithms, and in predicting the form of EM effects in induced polarization and magnetometric resistivity surveys.

Advances in interpretation techniques have made possible effective use of aerial high‐sensitivity gamma‐ray spectral data to explore for petroleum in selected environments. These data were collected by the U.S. Department of Energy during the National Uranium Resource Evaluation (NURE) program throughout the conterminous U.S. and most of Alaska between 1974 and 1981. The tests reported here were limited to portions of the following 1 degree by 2 degree National Topographic Map Series (NTMS) quadrangles: the west half of the Palestine quadrangle, the east half of the San Angelo quadrangle, and the southeast quarter of the Big Spring quadrangle, all of which are in Texas. The radiometric uranium and potassium data were normalized for surface lithology (including soil differences), as well as for variations in counting geometry and hydrologic conditions, using a new technique based on thorium measurements and geochemical relationships between thorium and potassium and between thorium and the uranium series. Uncontrolled effects of these variables have made many previous attempts at applying radiometric methods in petroleum prospecting essentially meaningless. The thorium‐based normalization approach described here resulted in anomalously low adjusted potassium values over most of the oil fields considered. Adjusted uranium analyses showed low anomalies over oil in east Texas and high anomalies in west Texas. The reasons for the different behavior of the uranium data are poorly understood, but they are attributed tentatively to the effects of the different climates on the distribution of the uranium series elements in very near‐surface soils. This application of high‐sensitivity gamma‐ray spectrometry has regional advantages and limitations, which depend on the nature, origin, moisture content, and possible shielding cover of the surface soils. If these factors are carefully considered, the NURE radiometric data offer promise as an inexpensive reconnaissance guide to help locate new onshore oil and gas prospects or possible field extensions in the East Texas Basin, the west Texas area, and similar environments.

ObjectivesTo summarise current data on the value of imaging to guide interventional procedures in patients with rheumatic and musculoskeletal disease (RMDs) informing an European Alliance of Associations for Rheumatology taskforce.MethodsA systematic literature review was conducted to retrieve prospective and retrospective studies published in English and comparing different (imaging) techniques, different settings and procedural protocols to guide interventions in patients with RMDs. MEDLINE, EMBASE, the Cochrane Library and Epistemonikos databases were searched through October 2021. Risk of bias (RoB) was assessed using the Cochrane RoB tool for randomised trials V.2 (ROB2), the RoB tool for Non-Randomised Studies of Interventions and the appraisal tool for cross-sectional studies.ResultsSixty-six studies were included (most with moderate/high RoB); 49 were randomised controlled trials, three prospective cohort studies and 14 retrospective studies. Fifty-one studies compared either one imaging technique with another imaging technique, or with palpation-guided interventions. Ultrasound (US) was most frequently studied (49/51), followed by fluoroscopy (10/51). Higher accuracy was found for US or fluoroscopy compared with palpation-guided interventions. Studies comparing different imaging techniques (12/51) did not endorse one specific method. Different settings/equipment for imaging-guided procedures (eg, automatic vs manual syringes) were investigated in three studies, reporting heterogeneous results. Fifteen studies compared different imaging-guided procedures (eg, intra-articular vs periarticular injections).ConclusionHigher accuracy of needle positioning at joints and periarticular structures was seen in most studies when using imaging (especially US) guidance as compared with palpation-guided interventions with the limitation of heterogeneity of data and considerable RoB.

Object. The authors describe their initial results obtained using a skull-mounted trajectory guide for intraoperative magnetic resonance (MR) imaging—guided brain biopsy sampling. The device was used in conjunction with a new methodology known as prospective stereotaxis for surgical trajectory alignment. Methods. Between January 1999 and March 2000, 38 patients underwent 40 brain biopsy procedures in which prospective stereotaxis was performed with the trajectory guide in a short-bore 1.5-tesla MR imager. In most cases, orthogonal T2-weighted half-Fourier acquisition single-shot turbo spin—echo (HASTE) images were used to determine the desired trajectory and align the device. The surgical trajectory was defined as a line connecting three points: the target, pivot, and alignment stem points. In all cases, surgical specimens were submitted for frozen section and pathological examination. Postoperative turbofluid-attenuated inversion-recovery and gradient-echo images were obtained to exclude the presence of hemorrhage. Trajectory determination and alignment was simple and efficient, requiring less than 5 minutes. Confirmatory HASTE images were obtained along the biopsy needle as it was being advanced or after reaching the target. All biopsy procedures yielded diagnostic tissue. One patient with a lesion near the motor strip experienced a transient hemiparesis of the hand related to passage of the biopsy needle, and another sustained a fatal postoperative myocardial infarction. No patient suffered a clinically significant or radiologically visible hemorrhage. Conclusions. In combination with prospective stereotaxis, the trajectory guide provided a safe and accurate way to perform brain biopsy procedures.

The aim of this study is to compare the implant placement deviations and evaluate the 1-year post-implant placement bone loss of pilot and fully guided implant placement protocols. In the first method, the pilot drill is used for guide surgery, and the following procedure is a method for performing implant surgery in a non-guided protocol. The second method is to perform fully guided surgery. A total of 74 implants in 20 patients were included. Postoperative CT scans were used to compare the implant placement deviations with the preoperative plan. In addition, bone loss was compared one year after surgery. In shoulder area, the implant deviations from the planned positions for dx(mesio-distal), dy(bucco-lingual), dz(vertical) dimensions, mean deviations with pilot-guided protocol (n = 31) were 0.50 ± 0.42 mm, 0.61 ± 0.55 mm, 0.87 ± 0.71 mm, and 1.33 ± 0.75 mm, respectively. The corresponding deviations for fully guided protocol (n = 41) were 0.50 ± 0.52 mm, 0.29 ± 0.27 mm, 0.56 ± 0.51 mm, and 0.96 ± 0.57 mm. In apical area, the corresponding deviations for pilot-guided protocol were 0.75 ± 0.72 mm, 0.61 ± 0.46 mm, 0.98 ± 0.76 mm, and 1.54 ± 0.87 mm. Deviations for fully guided protocol were 0.91 ± 0.90 mm, 0.44 ± 0.39 mm, 0.54 ± 0.51 mm, and 1.38 ± 0.76 mm, respectively. Angular deviations were 3.33 ± 3.23° with pilot-guided protocol and 3.90 ± 1.85° with fully guided protocol. The average bone loss after 1 year was 0.50 + 0.29 mm and 0.50 ± 0.24 mm, respectively. In the shoulder area, dy(bucco-lingual) of horizontal deviations, vertical deviations, and mean value of the deviations showed a statistically significant difference between fully guided and pilot-guided (p = 0.005, p = 0.033, and p = 0.023, respectively). In the apical area, vertical deviations showed a statistically significant difference. However, the mean value of the deviations did not show a statistically significant difference (p = 0.347). There was no statistically significant difference in angular deviations (p = 0.59).

This paper presents an exploratory and descriptive study on the use of the prospective research applied to the design management to generate innovation guided by the meaning. Innovation has been used as a key strategy for growth and maintenance of companies in the competitive market. However, in most cases, the development of innovation is either usually based on technological change, or on traditional market research. The first needs strong investment and time and the second relies only on the needs articulated by today's consumers, what limits the innovative results. In this context, as alternative approach, prospective research is considered a strong strategy, as it anticipates future consumer’s needs. Nevertheless, aiming at the designer’s work, there is a lack of information on how to manage it to foster meaning innovation by searching emerging opportunities using prospecting surveys. Therefore, this work aimed at the proposal of requirements to improve management of design in companies, by the use of prospective research to foster innovation guided by meaning. First, the research was conduct by a bibliographical review, with systematic and unsystematic phases followed by their interpretation and analysis that resulted in a preset of guidelines. From them, a Delphi method was conducted with manager’s and designers’ experts, to reinforce our review them. Confronting the previous results, the work proposes a list of requirements for the strategic, tactic and operational levels of design management. They intend to improve the use of prospective research within design management to generate innovation guided by meaning.

ABSTRACT Aims The present study was conducted in the fertility unit of a medical college to compare the implantation rate of embryo in ultrasound-guided vs clinical touch method of embryo transfer. Today, approximately 80% of women undergoing in vitro fertilization/intracytoplasmic sperm injection (IVF/ICSI) will reach the embryo transfer stage with good quality embryos. Traditionally, the ‘clinical touch’ method has been used to guide placement of the embryo transfer. The use of ultrasound to guide embryo transfer would allow accurate and atraumatic positioning of the catheter tip near the uterine fundus. Materials and methods A prospective study was conducted at fertility center of Mahatma Gandhi Hospital. A total 100 patients requiring IVF, from a period of July 2011—July 2013 were taken into the study. A total of 50 patients were subjected to USG-guided embryo transfer and 50 patients were subjected to clinical touch embryo transfer. Detailed patient history, clinical examination, relevant investigation and details of procedure were entered in a prestructured proforma. The data were entered and analyzed in Microsoft Office Excel. Results There was a significant improvement in the implantation rates in the USG-guided group (31.9%) as compared to clinical touch group (24.3%). There was also a significant improvement in the pregnancy rates in the USG-guided group (40%) as compared to the clinical touch group (28%). Compared with the traditional clinical touch method, the abdominal ultrasound-guided embryo transfer was found to have a number of advantages.

Background: The aim of the study was to evaluate the safety of fiberoptic bronchoscope guided percutaneous dilatational tracheostomy performed in the intensive care unit.Methods: This was a prospective clinical study done on 30 critically ill patients in Intensive care unit. A puncture was made with 16G cannula at the second or third tracheal interspace which was confirmed by the fiberoptic bronchoscope. This was followed by insertion of guide wire through the cannula followed by insertion of the guiding catheter over the guide wire. The tract was enlarged with white single stage dilator to allow placement of a standard tracheostomy tube. The procedure was continuously monitored with the fiberoptic bronchoscope. Complications were noted during procedure and till patient’s stay in Intensive care unit.Results: The study included 18 (60%) male and 12 (40%) female patients. The mean age was 64.5±8 years. Percutaneous dilatational tracheostomy was done early (<10 days) in 10 (33.3%) patients and late (>10 days) in 20 (66.7%) patients. Fentanyl was used for the procedure in all the patients and among them 8 (26.6%) patients required injection rocuronium. Average procedure duration, from incision to suture for 30 patients was 12.6± 2 minutes. Indication for tracheostomy was weaning failure in 22 (73.3%) patients and airway maintenance in 8 (26.6%) patients. The mean duration patient remained on mechanical ventilation was 12.6 days and mean length of stay in critical care unit before shifting to ward was 7.6 days after tracheostomy. Acute postprocedure complications were transient bleed in four patients (13.3%), two (6.7%) had stomal bleeding, one (3%) had tracheal mucosa laceration and another (3%) had subcutaneous emphysema. No cases of stomal infection, pneumothorax, tracheal laceration, paratracheal insertion, pneumothorax and pneumomediastinum. There was no procedure-related mortality. Conclusion: Fiberoptic bronchoscope guided percutaneous dilatational tracheostomy is safe and the method of choice for elective tracheostomy in the majority of intensive care patientsJournal of Society of Anesthesiologists of Nepal 2015; 2(2): 52-55

Introduction: As elsewhere in the world, Quebec (Canada) is currently facing the COVID-19 pandemic. Approximately 92% of deaths have occurred among people aged over 70, and approximately 100 long-term care (LTC) centers (termed CHSLDs in Quebec) were contaminated. This alarming situation is prompting stakeholders from healthcare networks to investigate the socio-economic repercussions of COVID-19. To the best of our knowledge, there is no valid and reliable tool to measure the costs associated with the management of COVID-19 in CHSLDs. Objectives: This research protocol aims to: i) adapt and validate for use in CHSLDs a combined guide, Cout-COVID19-SLD, developed from 2 guides used in acute care; ii) pilot the Cout-COVID19-SLD guide in CHSLDs and test its feasibility and afterwards resolve any barriers to its administration, and to conduct a partial estimate of costs brought about by COVID-19. Methods: A two-part prospective study will be conducted. Phase 1 will use a Delphi approach with 14 to 17 experts to validate the content of the Cout-COVID19-SLD guide. Phase 2 will pilot test the guide in a cross-sectional study in two CHSLDs. Discussion and conclusion: This study will provide a validated guide for the systematic measurement of costs associated with the management of COVID-19 (costs of preventive measures and costs of illness) in CHSLDs. Finally, this guide will serve as a valid and reliable instrument with which to better plan future research surrounding the socio-economic impacts of COVID-19 in CHSLDs.

Purpose The purpose of this paper is to analyse the risks associated with outsourcing production to emerging countries with lower labour costs, namely China, and study actions and plans used to reduce the influence of factors/drivers that induce these risks. Design/methodology/approach This research uses a multiple case-study methodology, involving seven Canadian manufacturing firms that have chosen an outsourcing strategy in China. It is based on a particular approach of classifying factors/drivers that may generate risks related to this strategy and on interviews with two managers per firm to reduce personal bias. Findings In each of the seven cases studied, outsourcing was chosen to take advantage of lower labour costs in China, but in reality, costs were higher than expected due to unforeseen factors inherent to the risks involved. This study reveals that risks generated by factors/drivers such as lack of experience, reduced control over foreign operations and cultural differences are of major concern for managers outsourcing part of their production to China. However, according to some executives that were interviewed, certain actions can be taken by firms to overcome the negative influence of these factors/drivers. Furthermore, some risks may have multiple causes or be induced by other risks. Research limitations/implications The sample of this study was composed of firms from different industrial sectors, and the authors were therefore unable to analyse sector-specific risks. As the industrial sector has an impact on the technical complexity of the products and their components, it would be appropriate to reconduct our research using samples drawn from similar sectors. Practical implications These findings can help guide the decisions of managers wishing to outsource some of their activities to China and other emerging countries. They will contribute to the success of outsourcing strategies to these countries, as they reveal the risks associated with these strategies and the ways to deal with factors/drivers that can induce them. For example, building long-term relationships with Chinese partners based on collaboration, trust and mutual benefit as well as conducting a rigorous prospecting phase and taking time to select the right subcontractor can have a major impact on reducing risks. Originality/value The main contribution of this work is the analysis of risks associated with outsourcing to China, based on a categorisation of factors/drivers that can generate these risks, and the study of how firms manage these factors/drivers and control their negative effects. The nature of the practices and actions used to manage important risks depends on the characteristics of the companies, their size, resources and the products they outsource.

Purpose The purpose of this study was to compare, in terms of blood loss and implant alignment, a new generation of smart extramedullary (EM) cutting guides with the conventional intramedullary (IM) guide for total knee arthroplasty (TKA). The hypothesis was that the EM system would result in less blood loss and fewer days of hospitalization, while ensuring equal or higher accuracy in the alignment of the femoral implant. Methods Thirty-six patients were enrolled for the present study: 18 patients underwent TKA using the EM guide and for the other 18 patients the IM guide was used. Preoperative and postoperative X-rays were acquired. The preoperative and postoperative hemoglobin values were compared. Lastly, length of hospital stay was recorded. Results The hemoglobin difference was significantly lower in the EM group. The alignment of the prosthetic femoral implant in the two groups was comparable but all patients in the EM cohort had a final alignment within 3 degrees of range on the frontal view, while 22% of the patients in the IM cohort had a final alignment exceeding 3 degrees of range. The mean hospitalization duration showed no significant difference between groups, though EM group showed 1.6 days less compared with IM group. Conclusions The inertial-based EM guide system could be useful for decreasing blood loss compared with conventional guide. This device tended to have better results even in terms of accuracy, but this difference was not significant. Level of Evidence This is a level II, prospective cohort study.

Background: Initiation of a long-term improvement of cardiac risk factors is one of the major aims of a cardiac rehabilitation/secondary prevention programme. Methods and participants: The Health Guide collected data in terms of cardiac risk factors: blood pressure, resting pulse, total cholesterol, LDL cholesterol, body weight, physical activity and number of cigarettes at admission and discharge after a stationary rehabilitation programme and every 3 months. After 12 months the Health Guides were returned. In the prospective study 2664 patients (71.8% men, age: MV = 62.94 years, SD = 9.96; 28% women, MV = 67.59 years, SD = 9.53) with coronary heart disease (CHD) were included. Results: All cardiac risk factors documented by the Health Guide improved during the cardiac rehabilitation programme. After one year, risk factors were significantly lower than at admission, apart from total cholesterol. The individual goal in terms of body weight and LDL cholesterol was partially achieved after the rehabilitation programme and maintained after one year. In the investigation years, 2004–2007, the cholesterol and blood pressure were significantly lower than in the years 2000–2003. Conclusion: The use of a Health Guide resulted in an improved long-term effect of a cardiac rehabilitation/secondary prevention programme. It is a simple and cheap intervention and can help in the guidance of the patients.

Supervised, center-based, daily physiotherapy presents limitations: transport, need for an accompanying person, or risk of infection. Home-based rehabilitation protocols (HBRP) can be effective alternatives. We use a HBRP for the non-surgically treated proximal humeral fractures (PHF) in older patients. Objectives To assess patient satisfaction and preferences of using a booklet, videos, or an app to guide physiotherapy. Patients and methods Prospective, single-center observational study of patients ≥55 years old who sustained a non-surgically treated PHF. The HBRP consisted of immediate mobilization, followed by 5 physiotherapist-guided, weekly sessions of rehabilitation and standard physiotherapy after 3 months, if needed. A booklet with images, videos, or a smartphone application were offered to guide the patients. Results Mean degree of satisfaction (1-5) was 4.66 ± .9: 84 patients (82.4%) were very satisfied, 11 patients (10.8%) were satisfied, and 5 patients (4.9%) were not satisfied at all. Mean Oxford Shoulder Score achieved was 40.5 ± 6.6. 59.8% patients preferred the booklet and 29.4% the videos. Exercise compliance was considered very high in 87.3% of patients, while 4% hardly never followed the HBRP. Only 17.7% patients needed center-based physiotherapy after the HBRP. Discussion Reasons for satisfaction were good final functional outcome, no need for transportation, being away from hospital, immediate rehabilitation availability and being capable of maintaining independence. Adherence is a major concern. Videos are more didactic explaining the exercises. Conclusion If standard physiotherapy is not available, the HBRP can be a valid treatment option for PHF management in older patients, with a high degree of patient satisfaction. Older patients preferred the booklet to guide physiotherapy.

Object. The goal of this study was to compare the freehand technique of catheter placement using external landmarks with the technique of using the Ghajar Guide for this procedure. The placement of a ventricular catheter can be a lifesaving procedure, and it is commonly performed by all neurosurgeons. Various methods have been described to cannulate the ventricular system, including the modified Friedman tunnel technique in which a soft polymeric tube is inserted through a burr hole. Paramore, et al., have noted that two thirds of noninfectious complications have been related to incorrect positioning of the catheter.Methods. Forty-nine consecutive patients were randomized between either freehand or Ghajar Guide—assisted catheter placement. The target was the foramen of Monro, and the course was through the anterior horn of the lateral ventricle approximately 10 cm above the nasion, 3 cm from the midline, to a depth of 5.5 cm from the inner table of the skull. In all cases, the number of passes was recorded for successful cannulation, and pre- and postplacement computerized tomography scans were obtained. Calculations were performed to determine the bicaudate index and the distance from the catheter tip to the target point.Conclusions. Successful cannulation was achieved using either technique; however, the catheters placed using the Ghajar Guide were closer to the target.
