When talking further about Funeral Officers in the Covid-19 era, many victims have died around the world, even in Indonesia, they have been buried by funeral officers either voluntarily or from the hospital. Funeral Officers during the Covid-19 period were an instrumental part of the formation of laws and regulations in practice, this is especially in regulating the Manpower Act, namely the Law of the Republic of Indonesia Number 13 of 2003 concerning Manpower (Law No.13-2003) and including in the Indefinite Time Work Agreement and Fixed Time Work Agreement. There has been no legal regulation regarding volunteer funeral officers in several statutory regulations. There must be legal protection for volunteer funeral officers or covering the bodies of Covid-19, both from medical and non-medical aspects, because this protection guarantee is also related to victims who are affected or as a result of carrying out duties as funeral officers or covering the bodies of Covid-19.

Published: February 2022

» Fractures of the growing scapula account for about 0.1% of all pediatric fractures, with the majority occurring at an age of ≥10 years.» Radiographic diagnosis requires a detailed knowledge of the ossification sequence of the growing scapula. Computed tomography examination is indicated for displaced fractures of the glenoid fossa, the scapular neck, and complex fractures; magnetic resonance imaging should be performed in cases of suspected injury to the physis and with stress fractures, depending on patient age and the potential need for general anesthesia during the scanning process.» Separation of the base of the coracoid process is often associated with acromioclavicular dislocation. Clavicular fractures rarely occur in combination with injuries to the growing scapula.» The majority of scapular fractures can be treated nonoperatively. Indications for surgery are displaced intra-articular fractures, scapular neck fractures with a displacement of >2 cm, coracoid base separation associated with acromioclavicular dislocation, and scapulothoracic dissociation.» Displaced intra-articular fractures of the glenoid fossa should be followed after healing until skeletal maturity. Complications are rare and occur most frequently with scapulothoracic dissociation.
Completion Designs in Horizontal Well with Transverse Hydraulic Fractures for Enhanced Recovery in Unconventional or Tight Reservoirs

Published: February 2022

Summary
Low recovery, 2 to 15%, in unconventional plays (including tight reservoirs and source rocks) has long been recognized as a business deterrent. The industry applies enhanced oil recovery (EOR) techniques, along with hydraulic fractures in tight/unconventional plays, to improve the recovery. To maximize matrix sweep, the fractures are aligned in a face-to-face assembly. Such an arrangement can be achieved using a vertical or longitudinal hydraulic fracture on horizontal wells, but these, generally, do not provide as effective reservoir contact (hydraulic fracture surface area) as horizontal wells with multistage transverse hydraulic fractures. The multistage transverse hydraulic fracture, however, comes at the costs of conformance issues with early water breakthrough from short-circuiting and inability to achieve fracture face-to-fracture face alignment of the injection and production fractures. The vast majority of wells drilled in unconventional plays are in the transverse configuration; hence, there is a need for an optimal solution for transverse fractures combined with improved oil recovery (IOR)/EOR approaches.
In this work, we introduce the multistage enhanced recovery (MS-ER) techniques that enable face-to-face alignment for optimal enhanced hydrocarbon recovery (EHR)/IOR/EOR in horizontal wells with multistage transverse fractures, thereby enabling optimal recovery and mitigating the key risk of fracture short-circuiting.

Abstract
This study is focused on the application of novel pozzolans (superplasticizers) ahead of cement, prior to casing and while drilling to treat and prevent wellbore fracture due to overburden stresses. This study is a combination of quantitative and qualitative analysis based on laboratory and field applications of pozzolanic materials in the construction of wells.
Pozzolans have long been applied to construction materials in order to improve lifespan and compressive strength. The application of pozzolanic materials goes back over 2000 years to the construction of Roman Aqueducts, buildings and roads known for their longevity and ability to resist corrosion and stress. These materials cover a broad range of naturally occurring and man-made materials. The most common pozzolanic materials used in drilling today include Bentonite, Kaolin, and Fly Ash. Pozzolans when combined with Portland Cement have been shown to increase the compressive strength and durability dramatically. Pozzolans are currently applied globally in cementing applications for HTHP, high loss zones and more.
This paper will examine the application in the drilling phase as an applied treatment during drilling for the reinforcement of the wellbore as well as to treat induced losses. The study will review cases for use of Novel Pozzolans for drilling, pre-cement, casing and for production zones the application of Novel acid soluble pozzolans for similar purposes. These applications validate the application of these materials beyond cementing into the drilling phase and wellbore construction for reducing backside pressure, reducing days on losses, reducing sidetrack, increasing operational ECD while drilling and cementing and achieving top of cement without inducing losses due to overburden in tight ECD window environments.
Deepwater environments provide a unique environment for the application of these novel materials as they offer some of the highest overburden environments with greatest operating costs and daily operating costs. Thusly this study has shown the applications have saved operators on multiple wells and over long periods many days and millions in operating costs with proven prevention of losses in field studies where wells were compared for offset value over a period of time. Multiple operators have adopted this technology as a result and there is a long track record of use while there are few papers on the subject. The purpose of this paper is to illustrate the best practices as well as new technologies and state of the art when it comes to the development of the latest in pozzolanics for these applications.
An Approximate Analytical Solution for Damage Radius Prediction in Water Injection Wells Based on Langmuirian Blocking: Derivation, Comparison and Field Applications

Abstract
Water flooding is extensively used in the industry to develop the mature oilfields. However, after several years’ of injection, the injectivity usually declines and the injection pressure increases. This is because the solid or liquid particles in the injected water are retained in the pores and block the flow channel in the near wellbore region. The prediction of the particle retention and permeability damage is important for the design of damage removal methods like acidizing.
Previous researchers including M. Nunes, P. Bedrikovetsky, Feike J. Leij, et al. have done some work on the analytical solutions of the flow of particulate suspension in porous media with particle retention and consequent permeability reduction. However, they either assumed one-dimensional linear flow in the porous media or took the filtration coefficient as a constant. These are not always true because the flow of the injected water near the wellbore is radial and the filtration coefficient tends to decline with more and more particles being retained in the pores and ultimately reaches zero when all channels are blocked.
In this paper, we established a near-wellbore axisymmetric suspension flow and particle retention model based on Langmuirian blocking, obtained the approximate analytical solution and compared it with the numerical solution. The results showed that the error of our approximate solution for the retained particle concentration is within 5%. Then we incorporated the analytical expression into the Darcy's law equation and derived the expression of pressure drop as well as skin factor caused by particle retention. Damaged zone radius was also defined so as to estimate the acid volume needed to remove the damage. We also checked our models and solutions using field cases of water injection and acidizing from Tarim Oilfields, western China. The results showed that the injection pressure drop due to particle retention and the injection pressure recover after acidizing calculated from our models are basically consistent with the actual situation. Our models can be further used to predict the damage zone radius and design the acid volume for damage removal. The analytical solution can also be used to perform sensitivity analysis for the parameters involved.

Abstract
This paper presents the architecture and features of RiskScape software. RiskScape is an open-source software with a flexible modelling engine for multi-hazard risk analysis. The RiskScape engine implements modeller-defined risk quantification workflows as ‘model pipelines’. Model pipeline steps and functions analyse hazard, exposure, and vulnerability data across different spatio-temporal domains using geoprocessing and spatial sampling operations. The RiskScape engine supports deterministic and probabilistic risk quantification, with several probabilistic-based modes described in this paper. RiskScape advances modelling software for multi-hazard risk analysis through several implementation features. The RiskScape engine operates model pipelines independent of system prescribed model input data classifications or standards. Multiple hazard types, metric intensities, and temporal occurrence information is geometry processed and sampled to create coverage data of simultaneous or sequenced multi-hazard events at object-exposure locations. Escalating multi-hazard event impacts are then determined for object-exposures using scripted conditional or nested statements that apply vulnerability functions in a logical sequence of temporal hazard and impact occurrence. These model features, supported by open geospatial consortium standard geospatial data files and operations, expedite RiskScape for modelling multi-hazard risk at any geographical location or scale.

Abstract
BackgroundMicrobial eukaryotes are nearly ubiquitous in microbiomes on Earth and contribute to many integral ecological functions. Metagenomics is a proven tool for studying the microbial diversity, functions, and ecology of microbiomes, but has been underutilized for microeukaryotes due to the computational challenges they present. For taxonomic classification, the use of a eukaryotic marker gene database can improve the computational efficiency, precision and sensitivity. However, tools which use marker gene databases often implement universal thresholds for classification rather than dynamically learning the thresholds from the database structure, impacting the accuracy of the classification process.ResultsHere we introduce taxaTarget, a method for the taxonomic classification of microeukaryotes in metagenomic data. Using a database of eukaryotic marker genes and a supervised learning approach for training, we learned the discriminatory power and classification thresholds for each 20 amino acid region of each marker gene in our database. This approach provided improved sensitivity and precision compared to other approaches, with rapid runtimes and low memory usage. Additionally, taxaTarget was better able to detect the presence of multiple closely related species as well as species with no representative sequences in the database. Several algorithms were implemented, including threshold padding, which effectively handled the scarce training data available and reduced classification errors. Using taxaTarget on metagenomes from human fecal microbiomes, a broader range of genera were detected, including multiple parasites that the other tested tools missed.ConclusionData-driven methods for learning classification thresholds from the structure of an input database can provide granular information about the discriminatory power of the sequences and improve the sensitivity and precision of classification. These methods will help facilitate a more comprehensive analysis of metagenomic data and expand our knowledge about the diverse eukaryotes in microbial communities.
