Published: September 2024

➢ The failure rate of treatment of nonunions of the distal femur with internal fixation and autologous bone grafting remains high at 20% to 30%.➢ Successful treatment of nonunions of the distal femur requires good mechanical stability combined with autologous bone graft. This may require dual-plate fixation or intramedullary nail-plate combinations.➢ Autologous bone graft remains the bone graft of choice. Bone-graft substitutes and biologics require further research.
Benturan Paradigma: Respons terhadap Penggeseran Paradigma Islam

Published: September 2024

The clash between paradigms, in this case the Islamic and Western paradigms, is inevitable. This cannot be separated from the globalization that has swept the world. Religious issues from various regions around the world are easily accessible to anyone, anywhere, and anytime. The influx of these issues shapes the patterns and attitudes of Muslims, both in dealing with external and internal problems. The problem is that Muslims are then forced to submit to the Western paradigm. Since the late 19th century, Western penetration of the Islamic world has at least forced some Muslim countries to adopt Western laws. In addition, Islamic academics and intellectuals have lately been moving towards a rationalism-nihilism paradigm that tends to be oriented towards Western orientalist thought and philosophy. As a result, the Islamic paradigm adopted as a framework for Muslims' thinking has shifted and been replaced with a secular-liberal Western paradigm. Therefore, Islamic law is considered to be in conflict with human rights and the way of life of modern society. Departing from that, this paper is important as a response as well as an analysis and offer that the Islamic paradigm is different from the Western paradigm, so that the products produced are also different. The Islamic paradigm is not just a view of the human mind towards the physical world or human involvement in it from a historical, social, political and cultural perspective, but includes aspects of the world and the hereafter.

An Integrated Solution in Utilizing Active Magnetic Ranging to Seal Off Underground Gas Storage: Theoretical Analysis and Field Test
Authors: Che Yang , Yuan Guangjie , He Ai Guo , Qiao Lei , Liu Tian'en , Fang Ming Xing 
Published: September 2024

Summary
In this paper, we describe a comprehensive technology based on an active magnetic ranging system (AMR) for sealing off the cement plug (CP) in the open hole (OH) section of the wellbore below the existing CP for underground gas storage.
Utilizing depleted oil and gas reservoirs for natural gas storage is an important approach toward achieving carbon neutrality. Sealing off old wellbores is prioritized according to relevant standards.
The challenge with OHs with CP is that there are no magnetic beacons in the wellbore, and the extent of compaction is unknown. Accurate placement of the seal-off CP is crucial because current technical methods, such as electromagnetic and acoustic waves, have limitations. Magnetic ranging technology, which is mature and widely used for wellbore interceptions or collision avoidance, requires magnetic beacons such as steel casing, drillpipes, or bottomhole assemblies left in the borehole. On the other hand, acoustic positioning techniques are applicable but presently complex to run operationally.
In this paper, we propose a comprehensive control technology. It starts by measuring the positional relationship between the subject wellbore (SW) and a magnetic beacon wellbore (MBW) using AMR. The data are then used in combination with additional skew data along with associate positional uncertainty or ellipse of uncertainty (EOU) to determine the location of the target wellbore (TW) and the MBW. By calculating the relative positional relationship between the SW and the TW, OH reentry below CP can be achieved within the EOU below the sidetracking point. After reentry, specific work such as crushing, element logging, caliper logging, and full hydrocarbon gas detection is performed to verify if the TW is still in the original position and if the caprock is properly squeezed and sealed off.
The comprehensive technique or method was tested on five wells in the Bohai Bay, successfully assessing the position of the OH wellbore and reentering below the CP. The process system expands the field of AMR and demonstrates significant industrial application value. It provides a new means of sealing off complex old wells.

Published: September 2024

Summary
An effective and accurate downhole communication strategy is crucial for the fabrication of an intelligent lifting system for onshore oil wells. Traditional communication approaches based on the wired cable, acoustic wave, vibration wave, or fluid pressure are usually limited by downhole conditions, and issues such as cumbersome implementation, limited communication, and unstable signal modulation are encountered. Herein, a novel downhole communication strategy is proposed using the loading waves in the sucker-rod pumping system (SRPS). The loading wave is altered at the downhole pump at an extremely low frequency, and its significant variation could be captured by the surface load sensor. A controlled valve is installed between the chamber of the pump and the wellbore. The valve opening regulates the pressure in the pump chamber, leading to the generation of the controlled loading waves. The field tests are further carried out and prove the effective coding between the downhole and surface with an acceptable delay (~0.154 seconds for a well with a depth of 1000 m). For the loading wave transmission on the sucker-rod string system, the finite element method is used to solve the theoretical model considering the real circumstances, such as the coupling damping, centering device friction, and stuffing box friction. The impacts of operating parameters of the lifting system, wellbore conditions, and modulation of excitation signal on the communication process are systematically discussed. The transmission evaluation standard, applicable conditions, coding tactic, and potential engineering values are presented for the downhole communication system.

Published: September 2024

Summary
Natural gas hydrates represent a promising and environmentally friendly alternative energy source, with horizontal wells being an effective method for efficient extraction. However, the drilling process of horizontal wells presents challenges due to the prolonged contact between the drilling fluid and the hydrates. This interaction leads to a significant influx of drilling fluid, triggering hydrate phase transition and causing instability within the wellbore. To address these technical issues, this study focused on decomposition-induced wellbore instability and reservoir structure damage during deep-sea natural gas hydrate drilling. Specifically, we investigated the stability of the gas hydrate phase during drilling shallow, deep-sea horizontal wells. To accomplish this, we established a 2D mathematical model that describes the nonsteady-state mass and heat transfer process between the wellbore and hydrate reservoir. In addition, we explored the mass and heat transfer mechanisms between the drilling fluid and hydrates, obtaining a 2D distribution of temperature and pressure fields within the wellbore and hydrate reservoir. The findings of this research contribute to the theoretical and technical development of safe and efficient drilling fluids for hydrate reservoirs.

Abstract

The safety of dairy products concerning foodborne diseases is a major concern worldwide. This is particularly true in developing countries, where milk and various dairy products are produced under unhygienic conditions and poor production practices. Milk is one of the food products consumed in South Sudan, however, there is limited information regarding its handling and safety, especially among the pastoral communities. Therefore, this study assessed raw milk's microbiological safety and quality at pastoral communities’ cattle campsites in Rejaf East Payam, South Sudan. A total of 240 households and 75 raw milk samples were selected at random. The findings revealed that the milking handling practices at cattle camps are characterized by hygienic and unhygienic practices. The pastoral communities had no access to a cooling system for milk storage. Additionally, 90.8% of the households in cattle camps consumed unboiled raw milk, and 10% of the households experienced milk rejection at the point of milk sale. The overall means of physicochemical parameters of milk samples were; fat = 7.76±1.47%, SNF = 7.68±0.26%, density = 1.03±0.00g/ml, lactose = 4.21±0.15%, protein = 2.81±0.09%, and pH 6.60±0.21. The result of the microbiological quality of raw milk indicated that the highest TVC (5.81 ± 0.51logCFU/ml) was recorded in Jebel Amianin cattle camp, on the other hand, the highest TCC (4.64 ± 0.21 logCFU/ml) was recorded in Kadoro cattle camp and TSC (2.53 ± 0.31logCFU/ml) recorded in Highland cattle camp. Furthermore, the study shows that the microbiological quality of raw milk samples is not within the standard and therefore there is a need to improve hygiene practices in milk production.
Inductive link prediction boosts data availability and enables cross-community link prediction in ecological networks

Published: September 2024

Abstract

Predicting species interactions within ecological networks is vital for understanding ecosystem functioning and the response of communities to changing environments. Traditional link prediction models often fall short due to sparse and incomplete data and are limited to single networks. Here, we present a novel approach using inductive link prediction (ILP), which leverages structural similarities across diverse ecological networks. Our model pools data across communities, and uses transfer learning to enable prediction within and between different ecological communities. We applied our model to 538 networks across four community types: plant-seed disperser, plant-pollinator, host-parasite, and plant-herbivore. ILP outperforms non-ILP models, particularly in host-parasite and plant-seed disperser networks. However, the efficacy of cross-community predictions varies, with plant-pollinator networks consistently under-performing as train and test sets. Moreover, we developed the first method to computationally estimate the limits of link prediction given a certain proportion of missing links, in which ILP performs better than a non-ILP model. This study underscores the potential of ILP to generalize link prediction across different ecological contexts.

Authors: Khan Maharaj , Jaman Abdullah , Ahmed MD. Faisal , Das Namrata 
Published: September 2024

Abstract

Background:PCOS is a common hormonal disorder that affects women's well-being. It is a chronic ailment without a cure, and poses a significant threat to women's health, with many going women untreated.Aims:Many women in Bangladesh lack knowledge about PCOS, leading to delays in diagnosis and treatment. This gap hinders the understanding of coping strategies, treatment options, and lifestyle improvements related to this condition.Methods:In total, 426 participants were included in this mixed methods study, and data were collected via a mixed-methods approach. A standard approach was used for the assessment of among Bangladeshi people’s knowledge about PCOS signs, and symptoms, causes, diagnosis, and treatment options, and impacts on health. The prevalence of diagnostic tests among people and the extent to which women are underdiagnosed were also determined.Results:A positive PCOS status had a significantly negative impact on mental health conditions. The knowledge levels about PCOS among participants were low (63.7%), moderate (21.6%), or high (14.7%). We found significant associations between knowledge level and age, education, occupation, place of residence, screening practices, and PCOS status (p-value <0.05). Notably, 63.4% of women in Bangladesh remain undiagnosed and have a symptomatic appearance.Conclusion:A significant number of women have limited knowledge about PCOS. Moreover, these studies failed to assess PCOS status, even though the prevalence of PCOS is more than thirty percent. Hence, it is important to arrange a health education initiative aimed at educating and encouraging women to actively engage in the diagnostic process to prevent PCOS complications.
Muon spectroscopy of a 12-phosphatetraphene with extremely efficient radical trapping properties

Published: September 2024

Abstract

This paper describes muon spin spectroscopy (µSR) studies of 12-phosphatetraphene stabilized by a peri-trifluoromethyl group and a meso-aryl substituent. Even though the prepared solution in tetrahydrofuran (THF) was quite dilute (0.060 M) for transverse-field muon spin rotation (TF-µSR) measurements, the π-extended heavier congener of tetraphene presented a pair of signals due to a muoniated radical from which the muon hyperfine coupling constant (hfc) was determined. This muoniated radical was produced by the diffusion-controlled regioselective addition of muonium (Mu = [µ+e–]) to the sp2-type phosphorus atom. The assignment of the muoniated radical structure was confirmed by observing a resonance due to the I = 1/2 (31P) nucleus in a muon (avoided) level-crossing resonance (µLCR) spectrum. The 31P hfc was determined from the resonance position, and a comparison with the value obtained from density functional theory (DFT) calculations indicated that the radical retained a flat π-delocalized tetracyclic skeleton. This higher energy structure is hypothesized to be preferable because of the increased zero-point energy of the light mass of the muon. The findings of this study could be fruitful in the development of novel spin-functional materials featuring efficient radical capture and π-delocalized paramagnetic molecular systems.
Thermodynamically Informed Multimodal Learning of High-Dimensional Free Energy Models in Molecular Coarse Graining

Published: September 2024

Abstract

We present a differentiable formalism for learning free energies that is capable of capturing arbitrarily complex model dependencies on coarse-grained coordinates and finite-temperature response to variation of general system parameters.
This is done by endowing models with explicit dependence on temperature and parameters and by exploiting exact differential thermodynamic relationships between the free energy, ensemble averages, and response properties. Formally, we derive an approach for learning high-dimensional cumulant generating functions using statistical estimates of their derivatives, which are observable cumulants of the underlying random variable. The proposed formalism opens ways to resolve several outstanding challenges in bottom-up molecular coarse graining dealing with multiple minima and state dependence. This is realized by using additional differential relationships in the loss function to significantly improve the learning of free energies, while exactly preserving the Boltzmann distribution governing the corresponding fine-grain all-atom system.
As an example, we go beyond the standard force-matching procedure to demonstrate how leveraging the thermodynamic relationship between free energy and values of ensemble averaged all-atom potential energy improves the learning efficiency and accuracy of the free energy model. The result is significantly better sampling statistics of structural distribution functions. The theoretical framework presented here is demonstrated via implementations in both kernel-based and neural network machine learning regression methods and opens new ways to train accurate machine learning models for studying thermodynamic and response properties of complex molecular systems.
