El presente, realiza un examen exhaustivo de las maloclusiones de cara larga, una condición facial que ha desconcertado a la comunidad científica durante un largo período. A través de una revisión bibliográfica en profundidad, explora las causas subyacentes y los factores contribuyentes de esta condición, destacando la intrincada interacción entre los aspectos genéticos y funcionales. El estudio revela que la génesis de la "cara larga" no puede atribuirse únicamente a un factor genético o funcional, sino que es el resultado de su interacción. Los factores neuromusculares, en particular, desempeñan un papel destacado en el desarrollo de las discrepancias esqueléticas y las maloclusiones observadas en pacientes con "cara larga". Se enfatiza la importancia del diagnóstico temprano para determinar el pronóstico y guiar un tratamiento integral, considerando tanto la normalización funcional como la estética del paciente. La tesis también presenta diversas opciones de tratamiento, que van desde enfoques ortopédicos y ortodóncicos hasta cirugía ortognática, según las necesidades individuales del paciente. Se destaca la importancia de la fase de retención en el tratamiento para mantener resultados a largo plazo, junto con protocolos de tratamiento ejemplares. En última instancia, esta investigación contribuye a una comprensión más profunda de las maloclusiones de cara larga y proporciona un marco integral para su diagnóstico y tratamiento. Además, subraya la necesidad de un enfoque personalizado en la atención al paciente para lograr resultados estables y satisfactorios estéticamente.

Evolution of the concept of history: a critical and comparative analysis
Authors: Crespo Jama Edri Alexander
Published: October 2023

This scholarly article investigates the evolution of the concept of history and its influence on the discipline of history. It begins with the medieval view of history as a source of moral lessons and progresses to Renaissance historicism, which emphasizes the contextual understanding of the past. It then explores the historical positivism of modernity, which seeks universal patterns and laws in history, followed by Marxist historical dialectics, which interprets the past as a class struggle. Subsequently, contemporary perspectives, such as cultural history, gender approaches, and global history, which broaden the understanding of history through new lenses, are addressed. In addition, the impact of digital technologies on the historical discipline is examined. A critical review of the various historical perspectives is undertaken, highlighting their contributions and limitations. This article underscores the importance of ongoing critical revision in the historical discipline to maintain its relevance and to consider ethical and political issues in historical narrative.
Discovery of Seven Volcanic Outbursts on Io from an Infrared Telescope Facility Observation Campaign, 2016–2022

Published: October 2023

This study analyzes near-infrared measurements of Io, Jupiter's moon, observed over 170 nights from 2016 to early 2022 using the NASA Infrared Telescope Facility (IRTF). During this period, seven new volcanic outbursts—the most energetic volcanic events on Io—were discovered and characterized, increasing the total number of observed outburst events from 18 to 25. We also present simplified criteria for the thermal detection of an outburst, requiring it to be both confined to a specific location of Io and above a threshold intensity in the Lp band (3.8 μm).

Our measurements use 2–5 μm photometry in eclipse, Jupiter occultation, and reflected sunlight. In addition to extending the observational data set of Io's dynamic activity, these data provide insights into the temporal and spatial distribution of outbursts on Io. Notably, all seven outbursts were detected in Io's trailing hemisphere. These include Pillan Patera and a newly discovered repeating outburst location at Acala Fluctus. We add these events to the rare category of recurring outbursts; before this, Tvashtar was the only known example. We observed that another outburst at UP 254W decreased in Lp-band intensity by a factor of 2 in 4.5 hr. In 2021 August, Io exhibited high volcanic activity when two powerful outbursts rapidly appeared, propagating east. Our findings underscore IRTF's ongoing contributions to the study of Io.
Aeetes: A Tragic Figure in the Argonautica of Apollonius Rhodius
Authors: Karamitsou Dimitra
Published: October 2023

The purpose of this paper is to examine the
transition of Aeetes from an epic to a tragic figure in the Argonautica of Apollonius
Rhodius. The Argonautica
is a generic mixture of both epic and tragic elements. On the one
hand, it is an epic poem based on Homeric aesthetics. On the other
hand, Apollonius differentiates himself from Homer by promoting
different values through his epic. Within the Argonautica, we can distinguish a
transition from an epic to a tragic poetic mode. In other words,
Apollonius composes an epic that consists of many minor tragedies.
Aeetes can be used as an example of this generic transition. He is
supposed to be a representative of archaic epic within the Argonautica. However,
although Aeetes is represented as an epic figure in the beginning of
the poem, he ends up being a tragic figure, in accordance with the
definition given by Aristotle in his Poetics.

On the Causality between FDI, International Trade Indicators, Energy Consumption, and CO2 Emissions in India
Authors: Rana Ritu , Sharma Manoj
Published: October 2023

The causal relationship between the consumption due to increased international trade and resultant CO2 emissions has been a subject of debate. This study examines the relationship between CO2 emissions and energy consumption along with global trade indicators for India using data from World Bank for the period 1982-2013. The study employed Augmented Dickey Fuller unit root test for stationarity among the variables, Johansen Cointegration technique to determine the order of the cointegration equation, and then the Vector Error Correction mechanism and Wald tests to check for short-run or long-run relationship among the variables. The results indicate that the variables are cointegrated. The VECM suggested no long-run causality from all the variables to CO2 emissions. Wald tests indicate no short-run causality also from FDI, exports, imports, and energy consumption to CO2 emissions but existence of short-run causality from trade openness to CO2 emissions. No long-run or short-run causality from FDI to CO2 emissions indicate the non-existence of Pollution Haven Hypothesis in India.
Particular Strength Criteria for Microstructural Analysis of Masonry
Authors: Cajamarca-Zuniga David , Kabantsev Oleg
Published: October 2023

This study presents a set of "particular" strength criteria of the constituent elements of masonry as a composite material constituted by homogeneous fragments of heterogeneous materials (brick and mortar) and contact interface (shear and normal adhesive strength). This paper proposes the expressions for calculate the values of each particular strength criterion used for the discrete modelling of masonry. The results were obtained based on the experimental study of stresses and failure modes in masonry specimens, mortar samples and brick units. There are determined a set of 8 particular strength criteria, which correspond to the actual work of the masonry constituent elements. Their use in the structural micromodelling of masonry allows to determine the body contact interactions, track the gradual accumulation of local stresses, exclude from the calculation model the elements in which a particular strength criterion has been exceeded, and modelling the degradation process.
Materials for Hydrogen Storage and Transport: Implications for Risk-Based Inspection
Authors: Giannini Leonardo , Alvaro Antonio , Campari Alessandro , Paltrinieri Nicola
Published: October 2023

The growing interest towards hydrogen technologies and their implementation in the hydrocarbon and chemical process industry makes maintenance planning of storage and transport equipment an emerging safety aspect. With respect to high-pressure working equipment, Risk-Based Inspection methodology (RBI) aims at minimizing the risk of loss of containment due to materials’ deterioration mechanisms. This set of procedures focuses on the mechanical integrity of equipment to achieve crucial risk mitigation by means of risk-informed inspection planning and maintenance activities. In addition, hydrogen-induced damages are often generalized or even neglected by the existing RBI standards and recommended practices. On this basis, high-pressure vessels, process piping and storage tanks working in gaseous or liquid hydrogen environments, which are exposed to hydrogen-induced deterioration mechanisms, might be subjected to an inaccurate evaluation of the associated risk and hazards when these RBI standards are applied. For this reason, this work proposes a review of the pipelines steels commonly used for gaseous hydrogen transport to investigate the possible limitations of the standard RBI planning methodologies, when applied to hydrogen technologies. More accurately, the pipeline steels’ susceptibility to hydrogen-induced degradations mechanisms will be discussed to underline assumptions and hypothesis limiting the conventional RBI applicability. Therefore, the overall suitability of standard RBI planning with respect to hydrogen equipment is discussed, highlighting possible relevant gaps as a general result.
An Approach for Grading of Soil Corrosiveness: A Case Study in Vicinity of Ring Road-Kathmandu
Authors: Dahal Kumar Prasad , Bhattarai Nootan Prasad , Bhattarai Jagadeesh
Published: October 2023

Corrosion of the outer surface of underlying Zn-coated or carbon steel pipes in the soil becomes complex and intricate due the insufficient information about the electrochemical interactions between discrete pairs of all corrosive soil factors. To overcome such corrosive problems of the underlying metal pipes in the soil, an ongoing study has suggested a stochastic approach for a close analysis of the corrosive grading of each soil specimen, sampled from the vicinity of Ring Road (RR) of Kathmandu, Nepal, towards the pipes with modifying the previously utilized AWWA (American Water Works Association), ASTM and NACE methods. Four corrosive grades (CGs) of all the soil specimens were categorized based on their quantitatively calculated soil factors in the stochastic approach of the novel probabilistic modeling (NPM) method. Then, they grouped supplementary ten corrosive sub-grades (CSGs) taking the sum of the cumulative point (CuP) of every soil factor. An indeterminate examination of 10 soil specimens was accomplished to categorize their CSGs, which would be a more precise method to draw a corrosive soil mapping of the study areas. The outcomes of such analysis under the NPM method imparted that about 90% of the sampled soil specimens of the RR areas allied only to five specific CSGs belonging to two CGs, i.e., G-RAR and G-MID.

This study deals with the hardening of titanium surface by carburising of CP Ti Gr 2 substrate by using laser sintering process. The objective of this project is to harden the surface to improve surface wear resistance of titanium. In this study graphite powder is used as source of Carbon. Carbon from graphite reacts with titanium and TiC layer of 109 micron was measured on the titanium surface. The microstructure and phase analysis results show that presence of only TiC phase on the surface of the titanium substrate. TiC grains are nearly 5 times finer than titanium substrate grains. Grain refinement of TiC phase all over the surface of the substrate resulted in increase in hardness and development of significant wear resistance surface in titanium substrate. Hardness of TiC layer was found to be 2191Hv which is nearly ten times higher than the substrate titanium. Wear test results of pin and disc type shows negligible wear rate as compared to CP Ti substrate. TiC grains are nearly 5 times finer than titanium substrate grains.

Authors: Anusha Suddala , Murthy Mora Narasimha , Sreelatha C.J.
Published: October 2023

Aluminum-doped NiO thin films were generated on glass substrates by dip coating at different temperatures (400 to 500 °C) using 0.05 M of the precursor nickel acetate. X-ray diffraction (XRD) and scanning electron microscopy (SEM) were used to investigate the structural and morphological aspects of the films. UV-visible spectroscopy was utilized to assess the optical properties of the films, and the energy band gap was confirmed to be 3.42,3.6, and 3.8 eV for as-prepared and thin films, respectively. Photoluminescence (PL) measurements were used to investigate electronic faults. The XRD lines of the transferred Al-doped NiO were strengthened due to the fact the film's temperature content increased due to the improved crystalline structure. This research article focuses on the optical properties and morphologies of thin films which have been deposited. Crystalline proportions of the thin films that were deposited were determined using the Debye-Scherer formula. The outcomes were computed after taking measurements of absorbance (A), transmittance and Band Gap.

The review article focuses on the growth of thin film and its characterization by UV-Vis-NIR spectroscopy. For UV-Vis-NIR spectroscopy of thin films, they are usually deposited on translucent quartz glass surfaces. The article reports the extraction of various thin film optical parameters viz., absorption coefficient (α), Urbach energy (Eu), optical band gap (Eg), refractive index (n), extinction coefficient (k), dielectric constants, dissipation factor (tanδ) and optical conductivity (σoptical) by using optical spectra (absorption(A)/transmittance (T)/reflectance (R)). Furthermore, the effect of thin film substrate temperature (Ts) and/or thickness (d) and/or post-deposition annealing temperature (Ta) on various optical parameters is discussed in detail.
Further evidence of the occurrence of the Atlantic blue crab Callinectes sapidus (Rathbun 1896) (Crustacea: Decapoda: Portunidae) along the central Tyrrhenian coast
Authors: Battisti Corrado , Chiesa Stefania , Gallitelli Luca , Scalici Massimiliano
Published: October 2023

We report evidence of the occurrence of the alien invasive crab Callinectes sapidus along the coast of Latium (central Tyrrhenian Sea, Italy). Original data refer to five adult females found in July 2022 in the Special Protection Area of “Torre Flavia” (Municipalities of Ladispoli and Cerveteri; IT6030020). Indirect evidence was obtained by web sources and personal communications by tourists and fishermen from the same site (including a juvenile reported on February 2023) and from neighbouring localities: Passoscuro (Municipality of Fiumicino), Santa Marinella, and Tarquinia. The Atlantic blue crab appears sparsely distributed along the coast of Latium, although its presence, even if still occasional, might prelude to a concerning scenario in relation to its high invasiveness. The Atlantic blue crab is known to have a severe impact on the invaded habitats, including the transmission of pathogens and parasites. Therefore, further monitoring aimed at collecting data about the distribution and population structure of this species are urgently required in order to develop strategies for the effective control of this non-native crustacean and the mitigation of its impact.
A scoring system for laparoscopic cholecystectomy to pick up difficult cases
Authors: Morsy Morsy Mohamed , Mohamed Salah Ibrahim , Abobakr Abobakr Mahfouz , Fadel Bashir Abouelsoued
Published: October 2023

Background

The conventional surgical treatment for cholelithiasis is laparoscopic cholecystectomy (LC), although some patients still require conversion to open cholecystectomy, primarily due to technical challenges. Risk factor prediction before surgery aids in determining intraoperative challenges. There are several rating systems that can be used to anticipate intraoperative challenges during LC. However, a trustworthy and consistent scoring and prediction system must be developed.

Aim and objectives

to reduce complications from LC and establish a score system to anticipate difficult LC before surgery.

Patient and methods

This observational cohort research, which involved 50 patients with calculous cholecystitis, was conducted at the General Surgery Department of the Assiut University Hospitals. One day before to surgery, all patients undergoing elective LC underwent scoring procedures. The intraoperative activities were all documented. Every patient got the usual postoperative treatment and monitoring.

Result

The preoperative score and LC results were significantly correlated.

Conclusion

The improvement of patient counselling, surgical planning, and postoperative expectations is made possible by identifying preoperative risk factors that indicate difficult LC. These variables also assist the surgeon in LC difficulty prediction and in maintaining a lower threshold for conversion under tough intraoperative situations.
Results of botox treatment in anal fissures (Our experience); Central Customs Hospital
Authors: Safiyeva Aynur K.
Published: October 2023

Introduction

Anal fissures appear clinically as a rip in the anal canal distal to the dentate line, causing agonizing discomfort during defecation. Acute and chronic anal fissures are the two types of anal fissures. Acute anal fissures usually heal fully within 5–6 weeks. Conservative treatment, on the other hand, loses value and becomes ineffectual as the anal fissure progresses to the chronic stage. Botulinum toxin injections are now commonly used to treat anal fissures in recent years.

Patients and procedures

24 patients with anal fissure were studied retrospectively at Azerbaijan’s Central Customs Hospital. The patients were divided into 15 females and 9 males. For the toxin preparation and injection operation, we employed 100 units of Botox Tip A. from Allergan in the United States. The purpose of the trial was to see how well botulinum injections worked for treating anal fissures.

The average age of the 24 patients was 46.92.5. There were two ladies and nine males among the 24 patients who were initially eligible for the trial. According to the location of the anal fissure, it was discovered that in men, the anal fissure is primarily positioned on the back wall of the anal canal, whereas in women, it is placed on the anterior wall and both walls. After botox, all patients experienced complete clinical improvement.

Conclusion

Botulin injection is a feasible surgical option for treating anal fissures and is considered a successful surgery.
Comparative study between stapled and open hemorrhoidectomy results with one-year follow-up
Authors: Salama Mostafa M. , Hossainy Ahmed F.El , Rihan Maged
Published: October 2023

Background

Hemorrhoids are one of the most prevalent diseases of mankind, affecting 4%–36% of the general population. Most patients are asymptomatic. Anal bleeding during the act of defecation is the most common presenting symptom. Many techniques were described for treatment, including stapled hemorrhoidectomy and conventional (open) ones.

Objective

The objective is to compare the effectiveness, short-term outcomes, and postoperative complications of stapled hemorrhoidopexy against open hemorrhoidectomy in the treatment of symptomatic primary piles.

Methods

A total of 76 patients were operated on at Al-Azhar University Hospital. They were divided into two equal groups: the stapled group (operated using a proximate PPH hemorrhoidal stapler of 33 mm) and the open group. All patients were followed for 1 year. Preoperative complaints, operative time and blood loss, postoperative pain, complications, and resumption of daily activities were recorded for both groups.

Results

Intraoperative blood loss and duration of operation were less in the stapler group. Postoperative bleeding, postoperative pain, and discomfort were less in the stapler group, with a significant difference from the open group. Healing and resumption of daily activities were faster in the stapler group. Regarding early recurrence, it happened in two cases in the stapler group and in the open group as well. There are no differences between both groups regarding urine retention. Anal incontinence did not happen in both groups. Mild anal stenosis occurred in one case in every group and occurred late.

Conclusion

Stapled hemorrhoidectomy is a promising procedure with less pain, a shorter duration of hospital stay, and a faster resumption of daily activity than open hemorrhoidectomy. However, long-term follow-up for many years is still needed to define the recurrence rate in stapled hemorrhoidectomy.
T3-T5 Thoracoscopic sympathectomy versus sympathicotomy in the treatment of palmar–axillary–plantar hyperhidrosis
Authors: Mahmoud Mohamed Mostafa , Allah Abd Elhady Mohamed Abd , Mohamed Mohamed Khidr , Abdu Mohamed Elsaeed
Published: October 2023

Background

Compensatory hyperhidrosis is a common complication after thoracoscopic interruption of the sympathetic chain in hyperhidrosis patients. Nonetheless, no interruption technique has been defined to decrease the incidence of that dreadful complication. Herein, we compared T3-5 sympathectomy with sympathicotomy at the same levels with regard to postoperative outcomes.

Methods

Eighty patients diagnosed with primary palmar–axillary–plantar hyperhidrosis were randomized into two equal groups: the sympathectomy and sympathicotomy groups. They were followed up for 6 months after the procedure. The incidence and criteria of compensatory hyperhidrosis were compared between the two approaches.

Results

The sympathectomy group showed a significant prolongation of the operative time. However, postoperative pain, hospital stay, and the incidence of complications were statistically comparable between the two approaches. Both procedures were associated with a significant decline in the severity of sweating in the three regions, which was more prominent in the palmar and axillary regions compared with the foot. The incidence of compensatory hyperhidrosis was 65% in sympathectomy patients and 77.5% in sympathicotomy patients, with no significant difference between them (P=0.217). About two-thirds of these cases were temporary, and the majority of them had mild to moderate symptoms. Patient satisfaction did not differ between the two approaches, with poor satisfaction in patients with permanent compensatory hyperhidrosis.

Conclusion

Both sympathectomy and sympathicotomy had comparable outcomes in patients with palmar–axillary–plantar hyperhidrosis, manifested in comparable decreased sweating severity, incidence of compensatory hyperhidrosis, quality of life, and patient satisfaction.
ESR1 and FTO genetic variants: impact on body weight reduction following bariatric surgery
Authors: Ramzy Tarek , El Zayat Susan , Sheta Marwa , Sarhan Mohamed D. , Elgaabary Tamer , Zeyada Reham
Published: October 2023

Background

Variation in reduction of body weight after bariatric surgery has been observed. Genetics may have a role in the varying outcomes among obese patients. Aim of this research work was to examine the effect of genetic variants within the Fat Mass and Obesity-Related gene (FTO) (rs9939609) and Estrogen Receptor Alpha gene (ESR1) (rs712221) on body weight reduction and blood glucose control in obese individuals, six months following laparoscopic sleeve gastrectomy (LSG).

Patients and methods

Ninety obese individuals with BMI ≥35 kg/m2 undergoing LSG were recruited and followed up after 6 months. Genotyping for FTO gene (rs9939609) and ESR1 gene (rs712221) variants was done using Real-Time PCR (TaqMan probes).

Results

FTO (rs9939609) genotype AA was found to be associated with more obesity before operation (P value 0.005) and lead to successful surgery and weight loss (P value 0.023, OR 0.080, 95%CI 0.009–0.702). Patients with risk allele A had more weight loss and BMI reduction after operation compared to patients with non-risk allele T (P value <0.001). ESR1 (rs712221) genotype TT was found to be associated with more reduction of body weight six months after surgery when compared to genotypes TA and AA (P value 0.001). Carriers of the allele T of the ESR1 (rs712221) had more reduction of HbA1c after operation compared to patients with allele A (P value <0.001).

Conclusion

The single nucleotide variants; rs9939609 of FTO and rs712221 of ESR1 may be considered potential predictors of body weight reduction and/or blood sugar control following bariatric surgery for obese individuals.
Omentopexy versus non-omentopexy in laparoscopic sleeve gastrectomy
Authors: Abdelrahman Emad M. , Abdelaal Mohamed K. , Kharoub Mohamed S. , El-Shaer Mohamed O.
Published: October 2023

Background

Laparoscopic sleeve gastrectomy (LSG) is a commonly performed bariatric operation nowadays all over the world. The most serious complications from this operation are postoperative bleeding and leakage. This study aimed to evaluate the effect of omentopexy in reducing the incidence of these complications.

Patients and methods

The current retrospective study included 82 patients who were eligible for sleeve gastrectomy and underwent one of the two procedures. Group A (n=41) underwent conventional sleeve gastrectomy without omentopexy and group B (n=41) underwent sleeve gastrectomy with omentopexy. Follow-up was designed for one month postoperatively for leakage or bleeding.

Results

The mean age of the eligible patients was 34.64±5.7 and 35. 32±5.42 years in group A and group B, respectively. No significant difference was reported as regards the sociodemographic data or patient comorbidities between the two groups. The mean operative time increased significantly in group B than in group A (P<0.001). There was no significant difference between both groups as regards postoperative leakage and bleeding.

Conclusion

According to the current results: omentopexy has no additional benefit in reducing the incidence of postoperative bleeding or leakage. However, it results in an additional increase in the operative time.
Transabdominal retro muscular versus intraperitoneal onlay mesh repair of ventral hernia: a randomized controlled study
Authors: Aziz Mahmoud A. , Elzeftawy Shady , Shemes Ayman , Elghrieb Ahmed , Abdelmaksood Moh , Shetiwy Mohamed
Published: October 2023

Background

Although laparoscopic ventral hernia repair has become a well-established alternative for open repair, traditional intraperitoneal mesh placement in direct contact with the bowel had many drawbacks and complications; in addition, it requires extensive mesh fixation and special composite mesh. Using the peritoneum and posterior rectus sheath as a barrier between the mesh and the bowel will evade these complications and decrease the cost.

Patients and methods

This prospective study was conducted in between May 2022 and December 2022 on 50 patients with noncomplicated ventral hernia with an average defect size of 5 cm. Patients were randomly allocated into two groups: intraperitoneal onlay mesh (IPOM) group (25) patients and transabdominal retro muscular mesh (TARM) group (25) patients. Both groups were compared as regards preoperative demographics, intraoperative complications and operative time and postoperative outcomes and complications.

Results

With a mean age of (44.96±7.27) of IPOM and (48.92±7.17) of TARM group, a significant longer operative time was spent in TARM repair (108.40±9.43 min). Postoperative pain was less in patients with TARM repair and hence they had earlier recovery and restoration of daily activities. Using a double-face composite mesh made the cost of IPOM repair significantly higher than TARM (P < 0.001). Overall postoperative complications and recurrence rate showed no significant difference between both techniques.

Conclusion

TARM repair seems to be a safe and good alternative to IPOM repair in terms of lower economic cost and less postoperative pain.
Intercostal artery perforator flaps for partial breast reconstruction after breast-conserving surgery
Authors: Fayed H.M. , Asal M.F. , Eldamaty A. , Alhussiny M.
Published: October 2023

Introduction

Breast conservative surgery’s objectives include a thorough oncologic excision and a satisfactory aesthetic outcome. The greatest strategy to prevent undesirable aesthetic outcomes is to use oncoplastic procedures to do so during conservative surgery in one step. For small to medium-sized breasts (up to C or D cup size), volume replacement treatments are advised, particularly in cases of bigger tumors. This entails inserting tissue into the tumor excision defect from a nearby or distant site. Musculocutaneous flaps, fasciocutaneous flaps, and most recently ‘perforator’ skin flaps have all been used in autologous tissue restoration. Due to the intercostal artery’s strong blood supply, anterior and lateral intercostal artery perforator (LICAP) flaps are dependable tissue sources. These flaps have the benefit of being able to fill the resection cavity, preventing further deformities. The study aimed to assess the feasibility of intercostal artery perforator flaps in partial breast reconstruction following breast-conserving surgery.

Materials and methods

The study was carried out on 42 breast cancer patients admitted to the surgical oncology unit, at Alexandria Main University Hospital in the duration between January 2021 and December 2022. A modified lateral intercostal artery perforator flap (mLICAP) and anterior intercostal artery perforator flap (AICAP) were used depending on the tumor location within the breast. The postoperative assessment was done by another breast surgeon and by the patient.

Results

Modified LICAP was used in 37 patients and AICAP was used in 5 patients. 90.5% of patients were satisfied with the aesthetic outcomes (85.7 gave excellent results). 69% of patients had excellent results based on the surgeon’s assessment. Complications were encountered in 11 patients in the form of seroma, hematoma, and minimal wound dehiscence.

Conclusion

Modified LICAP affords excellent access to the axilla and offers an option that facilitates both a pleasing aesthetic result and obviates the need for symmetrizing contralateral surgery to maintain breast symmetry. AICAP is a good option to partially reconstruct the breast following BCS for tumors located in the lower half of the breast.
Substantiation of Power Available and Inlet Distortion Compliance for Rotorcraft Engine Inlet Barrier Filter Installations
Authors:   S-12 Powered Lift Propulsion Committee
Published: October 2023

This SAE Aerospace Recommended Practice (ARP) identifies and defines methods of compliance with power available and inlet distortion requirements for rotorcraft with inlet barrier filter (IBF) installations. The material developed herein is intended to provide industry-recommended methods of compliance with civil airworthiness regulations. It is intended to serve as a basis for new or revised FAA advisory material describing acceptable methods for determining power assurance, establishing power available, and for substantiating acceptable engine inlet distortion for IBF installations. The ARP does not address other types of inlet protection systems such as inertial separator, electrostatic precipitators, or foreign object debris (FOD) screens. It is agreed to treat dust, ice, salt, water, and snow as contaminants to the IBF for the purpose of establishing power available and assessing inlet distortion, but any other effects of ice and snow on inlet airworthiness are outside the scope of this ARP.

A Critical Comment on T.S. Kuhn’s Views about the So-called Copernican Revolution and Several Current Prejudices – Barriers in Scientific Communities
Authors: Kokowski Michał
Published: October 2023

The article is a case study on the views of the famous T.S. Kuhn about the so-called Copernican revolution. Generally, Kuhn is presented as a very successful historian and philosopher of science: an author of world bestsellers. The division among his supporters, i.e. about so-called left-wing and right-wing Kuhnians, is recalled, and the fact that Kuhn himself vehemently dissociated from a large proportion of his adherents. It is also noted here, that in the last 30 years, in addition to abundant hagiographic literature on T. S. Kuhn, there have also been a few critical studies of Kuhn’s achievements.
The rest of the article presents the author’s critical analysis of Kuhn’s views on the so-called Copernican Revolution, which formed the basis of Kuhn’s scheme of scientific development presented in The Structure of Scientific Revolutions (1962); i.e. the world’s most famous monograph in social sciences and humanities so far.
The criticism encompasses a genesis, content and reception of Kuhn’s views and the development of his interpretations. The analysis is carried out by the means of methodology of historical sciences and a scientific method, which the author describes as the hypothetico-deductive method of correspondence thinking.
The criticism is based on the author’s current publications (developed here further on), which were sadly unnoticed by the researchers, although presented in the world center for the Copernican research, and are available on the Internet freely.
This fact leads the author to the assumption that international Kuhnian research is underdeveloped seriously and that strong prejudices – barriers may exist in scientific circles, such as, e.g., primacy of number of citations (and other bibliometric indicators) over content analysis, the Matthew effect, the effect of alleged and actual scientific centers and peripheries, some mental remnants of the Cold War, as well as underdevelopment of scientific communication.
Activity of the Committee of History of Mathematics at the Main Board of the Polish Mathematical Society in 1977–2000
Authors: Domoradzki Stanisław
Published: October 2023

In the article, we present operation of the Commission for the History of Mathematics appointed by the Main Board of the Polish Mathematical Society. From 1997 to 2000, the Committee was continuously chaired by Dr. Zofia Pawlikowska-Brożek, PhD in mathematics at the Jagiellonian University in the field of History of Mathematics, a student of an outstanding mathematician and respected teacher, Professor Dr hab. Zdzisław Opial (1930–1974).
Based on the documents, that the author received from the Chair of the Commission, we present how the activities of the Commission contributed to initiation of research on the history of mathematics, and to e creation of a professional community of historians of mathematics in Poland.
The history of mathematics has been a discipline well known in Kraków since the times of Ludwik A. Birkenmajer (1855–1929). His activities were successfully continued by Z. Opial. The issues of Kraków center for history of mathematics were presented by Domoradzki 2020; and Kokowski 2020, among others.
An important inspiration for the activities of the Committee were initiatives undertaken by the Department of History of Science, Education, and Technology of the Polish Academy of Sciences in agreement with the Committee of the History of Science and Technology of the Polish Academy of Sciences, in which the Chairwoman of the Committee actively participated.
The materials presented in the work cover also the period before the establishment of the Commission for the History of Mathematics.
Ideological, Political, and Philosophical Foundations of Science and Industrial Policy of the German Green Party in the 1980 and 1990: the Case of “Soft Chemistry” (Sanfte Chemie)
Authors: Krasnodębski Marcin
Published: October 2023

Sanfte Chemie, or soft chemistry, is a scientific and philosophical concept developed in the 1980s under the auspices of the German Green Party (Die Grünen). Its purpose was to thoroughly reconstruct not only the chemical industry but also chemistry as a science in the spirit of environmentalism. Soft chemistry followers wanted to forge a new scientific method and criticized what they called a Baconian-Cartesian paradigm in the philosophy of science. Even though the sanfte Chemie project ceased to be endorsed by the Green Party in the 1990s because of its radicalism, the history of epistemological foundations, on which the soft chemistry was built, gives us a privileged insight into a vision of chemical sciences as advocated by early proponents of sustainability and pioneers of environmental movements.
The article analyses sources of sanfte Chemie, highlighting plurality and complexity of scientific, philosophical, political and ideological traditions that served as its basis. The study of the eco-critical narratives on empirical sciences allows us to better understand subsequent political choices concerning science, industry and the environment in Germany. In particular, the article shows that the tradition on which sanfte Chemie was built, gives it the advantage over later concepts, such as green chemistry, that lack philosophical depth.
The purpose of the article is to question the relation between the philosophy of science and the practice of science and ponder whether different chemistry is possible at all.
The Misrepresentation of Petri Dish, as “petri” Dish, in the Scientific Literature
Authors: Teixeira da Silva Jaime A.
Published: October 2023

The Petri dish is, without a doubt, a very basic, yet important and popular tool in microbiological and other biomedical experiments. It serves primarily as a support or structural platform for placing, growing or testing biological specimens, whether these be microbiological, animal, plant or human.
Given its size, usually about 10 cm in diameter, the Petri dish is an ideal platform for cellular and tissue cultures.
Despite the commonality of Petri dishes, quite surprisingly, there is a pervasive error throughout the biomedical literature, namely its misspelling as “petri” dish. This is not a trivial issue since this dish is named after a scientist, Julius Richard Petri (1852–1921), so the upper-case “P” should not be represented as a lower-case “p”.
It is important to alert students and seasoned biomedical researchers, as well as the wider public, who might use this term, about the need to use the term Petri accurately, in order to respect its historical foundation.
To garner some appreciation of the extent of this error in the biomedical literature, a 2022 search on PubMed for either “Petri dish” or “petri dish” revealed 50 search results, 24 (or 48%) of which were of the latter, erroneous form in titles or abstracts. This suggests that the indicated error, which is in need of correction, may be widely pervasive in the biomedical literature.
High Neutrophils to Lymphocytes Ratio in Maternal Blood Serum as Risk Factor for Preterm Premature Rupture of Membrane

Introduction: Neutrophil-to-lymphocyte ratio (NLR) has been extensively studied as a prognostic factor for various diseases based on systemic inflammation. Premature rupture of membranes (PROM) is an obstetric problem that does not only occur in term pregnancies but can also occur in preterm pregnancies. One of the main etiologies for premature rupture of membranes is inflammation. Knowing the difference in the NLR between preterm prematurerupture of membranes (PPROM) and without PPROM is important to increase understanding of the crucial role of NLR in predicting the incidence of PPROM.

Method:  This analytic case-control study compared NLR values ??in maternal blood serum between PPROM and without PPROM. This research was conducted in the emergencydelivery room and obstetrics and gynecology outpatient clinic at Prof. dr. I.G.N.G. Ngoerah Hospital Denpasar from February to June 2022.

Results: A high NLR in maternal blood serum may be a risk factor for PPROM. Patients with a high NLR had a 4.5 times greater likelihood of experiencing PPROM than those with a low NLR (OR = 4.5; 95% CI = 1.4 – 13.83; p = 0.007).

Conclusion: A high NLR in maternal blood serum is a marker of inflammation with an increased risk of 4.5 times for the occurrence of PPROM.
