ACCESSIBLE TRANSPORTATION – UNIVERSAL OR INCLUSIVE DESIGN?
Authors: BĘCZKOWSKA Sylwia , GRABAREK Iwona
Published: December 2024

The accessibility of public utility buildings, including transportation infrastructure, especially railways, is a prerequisite for the independent functioning of individuals with diverse needs. Despite the enactment of the law in 2019 and its enforcement since September 2021, both architectural and digital accessibility, as well as information and communication accessibility, often fail to meet its requirements. Ensuring accessibility is undoubtedly a long-term process. It is easiest to achieve by designing new facilities in accordance with universal design principles, and somewhat more challenging when modernizing existing ones. Transportation, and therefore railway infrastructure, such as stations, terminals, and platforms, plays a crucial role in social life. This article presents various design strategies, with a particular emphasis on universal and inclusive design. It highlights the differences and similarities and demonstrates the validity of their application to ensure transport accessibility. General requirements for railway infrastructure accessibility are formulated, while detailed requirements specific to these types of facilities are incorporated into the developed accessibility assessment method, which has been implemented in a selected example of existing infrastructure. The article also presents the results of surveys on the accessibility of railway transportation for people with disabilities, confirming the need for auditing railway infrastructure. The results obtained allowed for the identification of the most common barriers that hinder individuals with diverse needs from using railway transportation freely.

Published: December 2024

The aim of this research is to explore the current urban transportation system of a megacity, Karachi. It was done by analyzing the Public Transport (PT) route network and commuter’s mode choice along with mode share. Four major arterials were selected for the study. Data was collected through field surveys and questionnaire-based survey. PT system of Karachi mainly consists of buses and minibuses. It was found that PT has 16% share in mode choice of Karachi’s travelers, which is less than most of the metropolitan cities in the world, and it has been decreasing constantly over the years. Most of the private vehicle users consider PT to be inefficient and uncomfortable. However, there is a willingness to use PT modes if they can provide at affordable prices. The current PT users are captive and women riders, which are bound economically or culturally to use these modes. Other sustainable modes of transport such as car-sharing and walking do not have significant share in mode share as well. Focused awareness campaigns for promotion of these modes should also be initiated.
DEVELOPING A CONTROLLER FOR AN ADAPTIVE CRUISE CONTROL (ACC) SYSTEM: UTILIZING DEEP REINFORCEMENT LEARNING (DRL) APPROACH
Authors: RIZEHVANDI Ali , AZADI Shahram
Published: December 2024

The addition of Adaptive Cruise Control (ACC) to vehicles enables automatic speed adjustments based on traffic conditions after the driver sets the maximum speed, freeing them to concentrate on steering. This study is dedicated to the development of a passenger car ACC system using Deep Reinforcement Learning (DRL). A critical aspect of this ACC system is its capability to regulate the distance between vehicles by taking into account preceding and following vehicle speeds. It considers three primary inputs: the memory-stored speed of the following vehicle, the lead time specified by the driver, and the radar-measured distance. By adapting speed in different traffic scenarios, the system contributes to averting potential accidents. This research delves into constructing a controller that utilizes the Deep Deterministic Policy Gradient (DDPG) algorithm and compares its outcomes with those from the DQN algorithm. The DDPG controller supervises the longitudinal control actions of a vehicle, enabling it to execute stopping and moving maneuvers safely and efficiently.

Published: December 2024

The article considers modern challenges and threats to the operation of ships in the liner form of traffic organization. Taking into account the dynamics of liner shipping development and its exceptional importance in ensuring international trade, it is proposed to analyze the main trends that are recorded both by statistical and analytical publications and by scientists from different fields of knowledge. Since any accident, under certain conditions, can be legally recognized as force majeure, maritime practice provides the widest range of challenges and threats to the commercial activities of enterprises. The originality of the review lies in the fact that the whole range of potential challenges is applied to the liner shipping sector. In this article, the analysis is done in several steps: 1) incidents that may have consequences of different nature (for human life and health, material losses, environmental damage) were grouped into 6 main groups; 2) articles indexed in Scopus Web of Science databases of the period 2020-2024 were investigated to substantiate the importance of these challenges specifically on international liner shipping; 3) the link between the challenges in ICC and BIMCO terminology and articles in relation to each of the proposed groups was established; 4) statistical material and individual cases for the same study period (2020-2024) for each group of challenges were provided to substantiate the importance of the impact on liner shipping. The study showed causal relationships between the challenges to liner shipping (such as geopolitics-economics link or forces of nature and economics/operational, etc.), correlation of scientific publications and recent challenges. In general, the article gives an idea of the content of modern threats to liner shipping in terms of source, interconnection of these threats and nature of consequences.

Authors: GREGA Robert , CZECH Piotr
Published: December 2024

Over the past ten years, the number of vehicles on the roads has almost doubled. The consequences of this state are negative effects, which include an increased number of road accidents and an increased level of harmful emissions into the atmosphere, along with other forms of environmental pollution. Road safety level is the sum of the safety levels of each element of the human-vehicle-environment system. In order to maintain the appropriate level of road safety, vehicles must be maintained in proper technical condition, and for this purpose, it is necessary to detect all types of damage at an early stage. All types of methods that allow non-invasive diagnosis of the technical condition of vehicles and their individual components seem to be extremely useful. It is important that they allow for detecting emerging faults in their early stages of development. Such tools undoubtedly include methods using vibration and acoustic signals as carriers of information about technical condition. Their appropriate processing and use in diagnostic systems that additionally use artificial intelligence makes it possible to meet the requirements for diagnostic systems. From a global perspective, this additionally enables the impact on reducing the costs of civilization development, including social costs. The article presents the use of various methods of processing vibroacoustic signals and artificial intelligence tools used to diagnose damage to combustion engines in cars.

Authors: KAŠŠAY Peter , URBANSKÝ Matej , GREGA Robert , KRAJŇÁK Jozef , KAČÍR Matúš , ŽUĽOVÁ Lucia , KUĽKA Jozef
Published: December 2024

Pneumatic couplings with constant twist angle control are suitable for tuning mechanical systems where the load torque is proportional to the square of shaft speed. This is typical mostly for drives of ships used in water transportation. In given conditions, the coupling maintains the ratio of natural torsional frequency to rotational speed of the mechanical system at a constant value. With proper setting of constant twist angle, resonance with harmonic excitation components in a specific range of operating speed can be avoided. The goal of this article is to present a design of a newly built prototype of coupling with mechanical constant twist angle regulator. During further research, it is planned to be tested in laboratory conditions.

The Anti-Microbial Effect of Elf on Breast Cancer Progress
Authors: Taheri Zahra
Published: December 2024

Aims Breast cancer is a heterogeneous disease and, according to Breast Cancer Statistics (CDC), ranks as the second leading cause of death among women. The intratumoral microbiota, a subject of recent research attention, plays a crucial role in the tumor microenvironment, contributing significantly to its repair and regeneration and serving as an effective therapeutic factor in cancers. Additionally, non-ionizing magnetic fields with extremely low frequencies (ELF-EFM) induce apoptosis, leading to the suppression of tumor cells. Studies have shown that ELF-EFM also plays a vital role in reducing bacterial cell counts. Therefore, by influencing the intratumoral microbiota population through ELF-EFM exposure, we can potentially address cancer and infectious diseases. Materials and methods ELF-EFM exposure for two hours per day with a frequency of 1Hz and an intensity of 100mT was investigated in triple-negative breast cancer (TNBC) mouse models and triple-positive breast cancer (TPBC) mouse models. After 28 days, the mice were euthanized, and the intratumoral microbiota population was examined using IHC tests (LPS/LTA) and real-time PCR (16SrRNA). Additionally, the mice's immune response was assessed by examining factors affecting tumor growth and metastasis: IHC (CD4/CD8, VEGF) and H&E (TILs). Key findings Significantly, TNBC mice in the exposure group did not show a significant change in tumor growth rate compared to the control group. However, TPBC mice in the exposure group exhibited a reduction in tumor growth rate compared to the control group. The number of Tumor-Infiltrating Lymphocytes (TILs) was lower in the TNBC exposure group compared to the TPBC group. In the intratumoral microbiota population, the number of Gram-negative bacteria, based on IHC test results (LPS/LTA) and examination of the expression of the 16SrRNA gene, was lower in TNBC mice compared to the TPBC group. Significance Our study results confirm the impact of ELF-EFM exposure on reducing the intratumoral microbiota population and inducing apoptosis, both of which are considered tumor cell suppressors.

Published: December 2024

The elimination of hydrocarbon pollution is a critical environmental challenge, often addressed using biotechnological approaches. The study of alkane oxidizing bacteria is an important task, as it will allow developing new approaches to oil pollution treatment and improving existing ones. Representatives of the genus Rhodococcus are well-known hydrocarbon-oxidizing bacteria with high biotechnological potential. A distinctive feature of some Rhodococcus species is the presence of multiple homologous alkB genes within their genomes. However, the reasons behind this redundancy and the functional diversity of the alkane monooxygenases encoded by these genes remain unclear. Furthermore, despite the significant diversity of alkB genes even within this single genus, a comprehensive classification system has yet to be established. In this study, we conducted a phylogenetic analysis of all AlkB family alkane monooxygenases identified in Rhodococcus genomes and examined the genomic context of their corresponding genes. Our findings reveal a remarkable diversity of AlkB enzymes, refine the classification of previously described AlkB types, and propose three novel types.For the AlkB0 type, we identified deviations from previously reported signature amino acid motifs. Our results highlight the key role of colocalization of alkane monooxygenase alkB genes with rubredoxin rubB genes in the further functional classification of alkane monooxygenases.
Auditors’ Life Cycle in Clients and Auditor Independence
Authors: Nwaeze Emeka T.
Published: December 2024

This study hypothesizes that, in client firms, audit firms or teams go through life-cycle phases—entry, adjustment, and recursion-that give rise to distinct patterns of independence across time. The life cycle paradigm depicts audit firms as facing pressures during entry to adhere strongly to their professional mandate, including strict exercise of independence. The result is tense auditor-client relations and an increased likelihood of auditor turnover during the entry phase. Auditors that gain entry will “loosen up” and adjust their stance on independence due to the reduced entry pressures. As a result, the adjustment phase will witness a decline in auditor-client disagreements and lower likelihood of auditor turnover. Over protracted periods, the audit process becomes tightly structured and recursive; the repetitive nature of the processes leads to audit fatigue, less attention to the independence mandate, and greater reliance on clients. The phenomenon portends even further decline in auditor-client tension and diminished likelihood of auditor turnover. These predictions are tested using auditor turnovers following auditor-client disputes as surrogates for auditor independence. The results confirm the life-cycle phenomena and show that the level of auditor independence peaks during the early years of the auditors’ tenure and declines afterwards.

Published: December 2024

Gravel sandstone reservoirs are characterized by low porosity, low permeability, and strong heterogeneity, presenting significant challenges for hydraulic fracturing. This study investigates the fracture propagation mechanisms in gravel sandstone formations using a combination of laboratory experiments, numerical simulations, and theoretical modeling. The findings reveal that gravel size, strength, and distribution significantly influence fracture morphology and propagation behavior. Under low stress differences, cracks tend to wind around gravel, while under high stress differences, cracks are more likely to penetrate gravel. Numerical simulations highlight the complex fracture network caused by high gravel content, leading to increased filtration loss, accelerated energy dissipation, and reduced fracture length. A quantitative model was developed to describe trans-gravel behavior, offering theoretical support for optimizing hydraulic fracturing designs in gravel sandstone reservoirs. This work provides valuable insights into the coupling mechanisms between gravel properties, stress conditions, and fracture propagation, contributing to more effective stimulation strategies for complex reservoirs.
On Summable Formal Power Series Solutions to Some Initial Value Problem with Infinite Order Irregular Singularity and Mahler Transforms
Authors: Malek Stephane
Published: December 2024

In this paper, we examine a nonlinear partial differential equation in complex time t and complex space z combined with so-called Mahler transforms acting on time. This equation is endowed with a leading term represented by some infinite order formal differential operator of irregular type which enables the construction of a formal power series solution in t obtained by means of a Borel-Laplace procedure known as k-summability. The so-called k-sums are shown to solve some related differential functional equations involving integral transforms which stem from the analytic deceleration operators appearing in the multisummability theory for formal power series.

Published: December 2024

In order to improve the vibration isolation effect of the floating raft vibration isolation system, a new experimental platform for floating raft vibration isolation with two stiffnesses was built. First, the mathematical model of the vibration isolation system was established. The vibration transfer function of the vibration isolation system was deduced by using the substructure derivative synthesis method and the four-end parameter matrix method. The transfer function under the structural parameters was calculated, and the influence of structural parameters on the vibration transfer function was analyzed. Then the floating raft modal test was carried out and the three-dimensional finite element model of the floating raft vibration isolation structure was established. The finite element analysis results were compared with the test results to verify the validity of the finite element model, and then the vibration characteristics of the support structure were studied. Finally, by measuring the acceleration responses at the upper and lower ends of the isolator, the difference is taken as the evaluation index of the vibration isolation effect to investigate the isolation effect of the isolator under the conditions of on-land and underwater usage, and to preliminarily explore its influence on the underwater acoustic radiation of the device. The results demonstrate that the vibration isolator with two stiffnesses can reduce the vibration transmission within a specific frequency range in both on-land and underwater application scenarios, which holds guiding significance for the research of vibration isolation technology in practical engineering.

Potassium permanganate (KMnO₄) is a commercially available antiseptic used in bovine intrauterine lavage to manage postpartum infections. Lipopolysaccharides (LPS) are well-studied for their ability to induce inflammation and oxidative stress. While KMnO₄ is known to cause significant irritation, oxidative stress, and toxicity in uterine tissues, its transcriptional impact and potential for inducing similar molecular damage as LPS have not been fully explored.
In this study, we induced oxidative stress in the uterine tissues of Sprague Dawley (SD) rats using KMnO₄ and compared the transcriptional profiles with those treated with LPS. We focused on the differential expression of long noncoding RNAs (lncRNAs) and messenger RNAs (mRNAs) related to oxidative stress, toxicity, and inflammation. RNA sequencing revealed 1125 differentially expressed mRNAs in the KMnO₄-treated group and 989 in the LPS-treated group. Additionally, 1649 lncRNAs were differentially expressed in the KMnO₄ group compared to 1383 in the LPS group.
Gene ontology (GO) and KEGG enrichment analyses showed that 78 pathways were significantly enriched in the KMnO₄ group, while 80 pathways were enriched in the LPS group, with 50 pathways shared between the two. This study offers critical insights into the transcriptional profiles associated with KMnO₄ exposure and its similarities to LPS-induced damage.
Ethical Considerations in Smart Grid Optimization Promoting Energy Equity and Fairness
Authors: Luo Dongwen , Zhong Jiachen , Wang Yiting , Pan Weihao
Published: December 2024

As the global climate security situation becomes increasingly severe, the development of renewable energy has become an important strategic direction for global energy transformation and addressing climate risks. Terminal energy electrification is a key measure to accelerate this strategic shift from the energy consumption end. By increasing the proportion of clean energy power supply in terminal energy consumption, it can reduce dependence on fossil energy, improve energy utilization efficiency, reduce environmental pollution, and promote sustainable development. Under the "dual carbon" goal, China proposes to build a clean, low-carbon, safe and efficient energy system, accelerate the construction of a new power system with new energy as the main body, and promote the large-scale optimization of clean power resources. However, China's power structure, which is dominated by thermal power, is heavily dependent on coal, and energy resources and power demand are inversely distributed. More than 80% of energy resources are distributed in the western and northern regions, while more than 70% of energy consumption is concentrated in the eastern and central regions. Against this background, the country has adopted macro-adjustment measures such as "west-to-east power transmission" and "north-to-south coal transportation" to optimize energy allocation and promote energy supply and demand balance. At the same time, the western and northern regions have borne many negative externalities of energy production transferred from the eastern and central regions, such as coal-fired power generation, carbon emissions in coal production, environmental pollution, and health impacts. In addition, for resource-based cities and high-carbon industry clusters that are highly dependent on fossil energy, In the short term, terminal energy electrification will increase the burden on economic income, energy security, reemployment, electricity costs, etc., and thus cause new regional social equity issues. Therefore, in the context of China accelerating the high-quality development of new energy in the new era and large-scale layout of renewable energy base construction, it is of great practical significance to focus on the three dilemmas of energy "security, equity, and ecology" and study and identify the spatiotemporal pattern characteristics and key influencing factors of the coupled coordinated development of regional terminal energy electrification and social equity.

Published: December 2024

The main aspects of color visualization of triangulated models of industrial products are presented. The implementation of visualization capabilities is based on RGB and HSV color models. The structure and key features of the software implementation of color visualization and the export of the displayed image in PLY, and AMF formats are discussed. Methods for transformations between RGB and HSV color models are described, as well as an algorithm for coloring the triangular faces of the model based on specified color ranges. The developed algorithms allow for a sufficiently informative representation of the desired areas of the product's surfaces by significantly altering one color component while minimally changing the other two. This is achieved by directing the assignment of functional dependencies and value ranges for each component of the color model. Examples of various methods for color shading of vertices and/or edges and/or faces of the model are provided. The visualization subsystem enables the analysis of the geometric characteristics of the polygonal model during the preparation phase of additive manufacturing processes. Significant advantages of these approaches to color visualization are evident when adapting the product design to technological requirements (design preparation) and when solving optimization tasks in technological preparation. The developed software is integrated into the technological preparation system for manufacturing enterprises in the machine engineering sector. This research was developed at the Department of "Integrated Technologies of Mechanical Engineering" named after M. Semko of NTU "KhPI".

Authors: Ol’shanskii A. I. , Kotow A. A. , Kuzmenkov S. M.
Published: December 2024

. The basic laws of the kinetics of drying thin flat materials during the period of drop in the drying speed are outlined. A method for calculating the average integral temperature of wet material on the basis of the relative temperature coefficient of drying is presented. Experimental data are processed based on the relative drying rate in the drying processes of ceramics, asbestos, and woolen fabric. A formula for calculating the average temperature is proposed. The solution of the differential equation of thermal conductivity for a wet plate during the drying process (namely during the period of drop in the drying speed) under boundary conditions taking into account the conditions of drying is given. The calculation of the heat transfer coefficient is given, too. Based on the study of various sources and processing of experimental results, formulas for calculating the thermal conductivity coefficient of wet materials have been presented. The analytical solution of the problem confirmed that during convective drying in low-intensity processes of the second drying period, the temperature change with a decrease in moisture content turns from an exponential dependence smoothly into a linear one, which is completely consistent with the experiment.  A comparison of the temperature calculation by the experimental formula with the results of analytical solutions has been presented. A sufficiently reliable coincidence of experimental and calculated analytical values of temperature for the period of drop in speed drying of ceramics, asbestos, and fabric is obtained.

Published: December 2024

The article discusses issues related to the actual condition of pre-insulated (PI) pipelines of district heating systems (DHS). Some of the pipelines in operation are approaching their estimated service life, so the issue of their further use is relevant. The aging of the heating supply pipelines occurs due to various processes associated with both operating temperature regimes and oxidation. The durability of polymer materials used in pre-insulated pipes can be assessed through empirical or predictive methods. For six batches of PI pipes that were in operation at different times in the Minsk DHS, tests were carried out according to standardized parameters in order to determine their actual values. For most of the samples presented, the values of the average cell size, thermal insulation density, compression strain stress and the number of closed pores significantly meet the requirements of STB 2252–2012 for new pipes. The value of the thermal conductivity coefficient is in the range of 0.030 to 0.037 W/(m·K), which is 10 % higher than the required value for new pipes. Values of the shear strength limit of the pre-insulated pipe construction  in many tests was less than 0.12 MPa, indicating a potential risk of failure in the thermal insulation structure of the pipe. Besides, there is no specific correlation with either the service life of the pipes or the temperature regime.
Your Oil Industry and You

Published: December 2024

Article I, Sec. 2, of the Society by-laws states: "The object of the Society of Petroleum Engineers shall be to furnish a medium of cooperation among those interested in the petroleum-natural gas industry and to promote the advancement of this branch of mineral technology through meetings to stimulate the preparation, reading, discussion, and circulation of papers connected therewith". Wisely, that's all it says. Within the scope of its objective, the Society is doing an excellent job. Our publications compare favorably with those of the other professions, and our meetings leave little to be desired in papers, communication and fellowship.

I would be the last to advocate any change in the Society's objective. Change would result inevitably in deterioration of both the quality of and participation in our meetings. Due to the diversity of membership in the Society-a diversity even more pronounced in the Institute- the development, collection, and exchange of technical information is probably the only basis upon which we all can meet and be of mutual benefit. This common ground gives us plenty of latitude. Let's keep it that way, and make full use of it.

However, important as it is, technology isn't the only thing needed to produce petroleum at a profit. Within broad limits, our welfare and progress as individuals and as a profession depend upon the welfare and progress (continued operation at a profit) of the companies that employ and pay us. And again within broad limits, these companies can be no more prosperous and can fare no better than the industry as a whole. Therefore, while it is outside the objective of the Society to consider many of the problems that affect the industry, we cannot, as engineers who have chosen the oil industry to provide us with the bulk of the material things we want from life, ignore and evade these problems and expect solutions meeting the standards we set and attain for our technology.
Conservation and Well Spacing
Authors: Bowie W. H.

The industry is confronted continuously with problems concerning conservation rules and practices in regard to well spacing.

The optimum solution to these problems requires careful planning, action and cooperation of state legislative bodies, state regulatory bodies and the industry itself. Each of these groups has already made great strides in this field; however, the industry should supply the foundation of a constructive program for further improvements in conservation and well spacing rules where needed.

In 1924 W. W. Cutler, of the U. S. Bureau of Mines, studied oilwell production data and concluded "That the ultimate production for wells of equal size in the same pool where there is interference seem approximately to vary directly as the square roots of the areas drained by the wells".

This rule, made famous by misinterpretation, has since been used erroneously by many operators as meaning that the more wells drilled to a given reservoir, the more oil will be recovered therefrom. This impression has been proved wrong by recognized petroleum technology. Over the years since Cutler published results of his work, there has been spirited controversy between those who for various reasons desired closely spaced wells and those who recognized the fundamental soundness of widely spaced wells. Now, 35 years later we still find operators in the industry who would, even with good engineering knowledge available, still over develop oil and gas producing properties at great economic waste in expense and capital investment, and sometimes in flagrant violation of equitable property rights.
The Engineering of Managers

Considering the entirety of mankind's recorded history-some 5,000 years-90 per cent of our technological accomplishments have occurred in the last 2 per cent of the time span.

Under this pressure of change, management - while still an art - has acquired many of the trappings of a profession, with its own particular skills and methods, its analytical approach and its code of ethics. Beyond that, it increasingly has tended to become a· science as well, requiring a greater understanding in depth of technology and engineering.

Since this is the case, it is only logical that business today looks increasingly to the engineer and the scientist for its managerial talent. Their particular background of education and experience gives them definite advantages over management candidates from other fields, provided, of course, that they can develop the non-technical skills and know-how that are necessary.

It therefore behooves the engineer to take a long careful look at himself and at his qualifications. Assuming that he wants to become a member of the management team, he must prepare himself for the successful performance of the broader responsibilities that will follow.

On observing his associates in the business world, he will conclude at once that many have demonstrated outstanding capabilities as top-flight administrators and executives. He will also become aware that many others - too many in view of the increasing demands for top talent-have failed.

This question of success or failure becomes immediately a serious challenge to both management and engineers. We must try to find why some succeed and some fail. We must develop a body of information that will permit us to select, train and refine technical men into predictably successful managers. We must be able to know that the engineer promoted to a management position will make the grade. In short, we must become expert in the engineering of managers.
Are We Meeting the Union Challenge?

Early this year in Washington, the AFL-CIO held a conference on Labor and Science in a Changing World. In attendance were representatives of various labor groups, as well as people from government, industry and education circles. One of the chief conclusions of a union panel discussion dealing with the needs of scientific and professional workers was the thought that unions must push the idea that industrial scientists and engineers are no longer professionals because they are so numerous. They are now "mere employees'' and need the powers of collective bargaining.

Similarly, the newsletter of the National Society of Professional Engineers regularly announces such items as the fact that engineers and architects at the Chicago office of Standard Oil Co. of Indiana voted for union representation through the Research and Engineering Professional Employees Association. The group had voted for "no union" in 1957. REPEA now represents approximately 550 professional employees at the company's Whiting, Ind., plant.

The growing effort of organized labor to "reach future scientists on the campus before professional societies can get to them" is presenting a more and more serious challenge for professional societies which have been devoted to the idea of professional performance. Throughout the country, growing effort is being expended, not only to contact young people in their formative years, but also to attempt organization of scientific and engineering personnel now in industry. The professional societies are being strongly blamed for "poisoning" the minds of engineering students against collective bargaining and unionization.

While this program is being conducted vigorously and on a growing basis, all of us should be aware of the increasing political activities of labor unions throughout the country. Traditionally, engineers and their professional societies have stayed aloof from political problems, but now the very fundamentals of our way of life are being attacked. In this atmosphere, the future of engineering as a profession is clearly related to the future of the entire free-enterprise concept in our economy, and it is to the interest of every engineer to be aware of what is happening and to take an active interest in trying to reverse the trend.
Recommendations for recognizing and diagnosing Acute Hepatic Porphyria in atypical patient populations
Authors: Schmolly Katharina , Rudrapatna Vivek , Beaven Simon
Published: December 2024

Background
Acute Hepatic Porphyria is a group of four rare genetic but treatable diseases that often go undiagnosed due to its non-specific symptoms, under-recognition of the condition by clinicians, and the lack of access to specialists and appropriate testing. This case-control study investigates the phenotypic and demographic patterns in Acute Hepatic Porphyria (AHP) patients at a tertiary care center (University of California Los Angeles) to update recommendations for recognition and diagnosis of this disease in our community.
Method
A retrospective chart analysis was conducted on 45 patients who were evaluated for AHP, Electronic Medical Record (EMR) data was collected and analyzed to investigate clinical differences and correlations.
Results
27 patients tested positive for AHP through urinary metabolites and confirmatory genetic testing and 18 patients tested negative; of those, 16 patients received a definite alternative diagnosis. Hashimoto’s, T1DM (Type 1 Diabetes Mellitus), Fibromyalgia and cannabinoid use with cyclic vomiting syndrome were negatively correlated with AHP, while psychiatric disorders and OBGYN disorders were positively correlated with AHP. The highest rate of diagnosis resulted from a combination of genetic and biochemical testing. Testing outside of an acute attack was not associated with a positive diagnosis.
Conclusions
Patients with a history of OBGYN disorders and psychiatric disorders may be at increased risk of having AHP, yet there is a lack of involvement of these specialties in the diagnosis and care of AHP, in addition to a lack of studies investigating AHP in non-white populations potentially leading to reduced recognition of AHP.
