Modélisation architecturologique et poïétique générale
Authors: Boudon Philippe
Published: February 2025

Une visée commune à la génétique – textuelle ou architecturale – et à l’architecturologie peut être dite « poïétique ». Diverses approches, artistiques, scientifiques, régionales, générales, procédant de démarches a priori ou a posteriori, peuvent différencier génétique et architecturologie à l’égard d’une éventuelle poïétique générale. S’appuyant sur la réduction architecturologique de la conception à la mesure, la modélisation architecturologique, exposée ici de façon succincte, offre la possibilité d’effectuer d’éventuels rapprochements entre « faire » architectural et « faire » littéraire selon des formes de conception symbolisées. À la lumière de cette modélisation, le dispositif du plan-libre, caractéristique majeure de l’architecture moderne, est interprété comme « scène » pour des scénographies variées, témoin possible d’un changement contemporain de mode poïétique, allant de la composition à la disposition. La distinction entre conception et création laisse entière le mystère de celle-ci, dont l’hypothèse est proposée toutefois, que ce mystère se loge dans l’opposition, ou mieux, la conjonction, du synchronique et du diachronique.
Archigenèse d’une histoire vraie
Authors: Le Bihan Loig
Published: February 2025

Au moment même où Une histoire vraie (The Straight Story, David Lynch, 1999) sortait en salle, les lecteurs du scénario tout juste paru pouvaient relever qu’il prévoyait un plan de route filmé en travelling au son de « “Born to Be Wild” à la Easy Rider ». Or, si le plan a fait son chemin jusque dans le film, c’est au son d’une musique originale, ce qui efface la possibilité de reconnaître la référence à l’un des tout premiers road movies, qui a participé à fixer les caractéristiques du genre. Ce fait donne à penser que les co-scénaristes avaient bien en tête ce genre lorsqu’ils fictionnalisaient l’histoire vraie d’Alvin Straight. Si leur enquête documentaire a en effet pu nourrir le développement du film, on éprouve dans cet article l’hypothèse selon laquelle cette connaissance du genre a également participé de la réinvention de l’anecdote. L’article prend occasion de l’étude de cas pour constater l’effectivité d’une « archigenèse » – d’une genèse conduite par un architexte – et pour définir la notion comme pour argumenter son utilité dans le cadre d’une génétique filmique, où l’on a souvent affaire à des œuvres fortement déterminées par un système de genres.
Mettre la science politique au service du développement ?
Authors: Deforge Quentin
Published: February 2025

De 1966 à 1978, la United States Agency for International Development (USAID) a financé les Comparative Legislative Studies, aujourd’hui devenues Legislative Studies. En s’appuyant sur des archives de la USAID, ainsi que sur certains des travaux que ces financements ont permis de produire, l’article montre que la formation de cet espace académique n’est pas le produit d’une logique hétéronome. Elle est au contraire le produit de l’importation au sein de l’agence de concurrences existant dans le champ académique entre des économistes, et des politistes qui ont bénéficié de ces financements en promettant de produire, au nom du « développement politique », des savoirs qui devaient permettre de « développer » les parlements les pays du Sud. In fine, ces derniers ont cependant essentiellement contribué à former un espace académique selon leurs propres intérêts, en le structurant autour d’une approche comparative, alors que les travaux étasuniens sur les parlements étaient jusqu’ici centrés sur le Congrès.

Authors: Gumilar Mulus , Mulyo Gurid Pramintarto Eko , Evianda Dila , Fauziyah Roro Nur
Published: February 2025

Diabetes mellitus is characterized by hyperglycemia and metabolic dysfunctions in carbohydrates, fats, and proteins, primarily due to impaired insulin action and/or secretion. Dietary fiber can help delay carbohydrates conversion to glucose, slow the rise in blood sugar, and aid in blood sugar regulation. This study aimed to evaluate the effects of red rice flour and red bean flour formulations on the sensory characteristics, fiber content, and nutritional value of kwetiau. The research utilized an experimental design with a completely randomized design (CRD) framework. Methodologies included hedonic tests to assess organoleptic properties, enzymatic gravimetry for fiber content, gravimetry for water and ash content, the Kjeldahl method for protein content, Soxhlet extraction for fat content, and calculations for carbohydrate and energy content. The formulations tested included F1 (80% red rice flour and 20% red bean flour), F2 (75% red rice flour and 25% red bean flour), and F3 (70% red rice flour and 30% red bean flour). Among these, F1 was identified as the most favorable. The Kruskal-Wallis test showed no significant differences in organoleptic properties such as color, aroma, taste, texture, and overall sensory acceptance. The nutritional analysis of F1 revealed a fiber content of 2.93%, water content of 67.2%, ash content of 0.43%, protein content of 1.98%, fat content of 2.45%, carbohydrate content of 27.9%, and energy content of 147.95 kcal per 100 grams. Future research should assess the efficacy of kwetiau, made with red rice and red bean flour, in managing diabetes mellitus.

Authors: Behboodi Behrooz , Gholami Parashkoohi Mohammad , Zamani Davood Mohammad , Firouzi Saeed
Published: February 2025

The assessment of energy usage in the production of ostrich meat and eggs provides a comprehensive analysis of energy consumption and production efficiency. The energy consumption per 1000 units is 1,086,825.54 MJ for meat and 1,197,794.25 MJ for egg. When considering protein supply, egg production seems to be more justifiable in terms of energy efficiency compared to meat production. This study delves into the impact of egg and meat production on human health, revealing a slight difference of 0.23 disability adjusted life years (DALY), hinting that egg production could potentially have marginally more negative health effects than meat production. Artificial neural network (ANN) analysis indicates that optimizing machinery, diesel fuel, and energy usage can enhance the productivity of meat production. It also suggests that there is a possibility for greater resource efficiency in egg production as opposed to meat production, highlighting that a focus on resource efficiency within egg production could yield positive environmental and energy benefits. Additionally, the coefficient of determination in the adaptive neuro-fuzzy inference system (ANFI) 4 model indicates a more favorable outcome for factors related to meat production compared to those for eggs production. Moreover, the low mean squared error value reflects the high accuracy of the results obtained in the analysis.

Authors: Singh Pooja , Anchukandan Ramees A , Karna Sunaina T , Niwariya Yogesh , Waindeskar Vaishali , Kumar Harish , Padala SRAN Bhushanam , Kiran Molli
Published: February 2025

Background and Objectives:

The quality of life may be negatively impacted by postoperative cognitive dysfunction (POCD) following off-pump coronary artery bypass grafting (OPCAB). It is still unclear how useful the jugular venous lactate and oxygen parameters are in predicting POCD following OPCAB.

Methods:

This prospective observational study was conducted over a period of 15 months and included 54 individuals. It sought to determine the sensitivity and specificity of jugular venous lactate and oxygen parameters for early POCD prediction in patients undergoing OPCAB. Neuropsychological tests were conducted to assess baseline cognitive function. Under ultrasound guidance, the jugular bulb was cannulated. The jugular venous lactate and oxygen parameters were measured at the time of surgery, following each graft, and 6 and 24 h later. Confusion assessment method-intensive care unit score was assessed on the third postoperative day for postoperative delirium (POD). POCD was defined as a composite Z score ≥1.96 or two Z scores in individual tests at 1 week. The jugular venous lactate and oxygen parameters of the Decline (D) group were compared to those of the Normal (N) group. Receiver operating characteristic curves were used to assess the diagnostic efficacy of derived variables.

Results:

The incidence of POD and POCD was 18.5% and 11.1%, respectively. At T3, all derived variables showed a significant increase, although the arterio-jugular venous lactate difference (AJDL) and modified lactate oxygen index (mLOI) were substantially greater at T3 in group D compared to group N. When predicting POCD, mLOI demonstrated the highest sensitivity at 72.22%, while AJDL showed the highest specificity at 90.7%.

Conclusions:

For prediction of early POCD in patients undergoing elective OPCAB, mLOI had highest sensitivity, while AJDL had high specificity.
Predictive Factors of Early Neurologic Deterioration in Isolated Pontine Infarction
Authors: Gao Shan , Wu Wenbo , Yang Haocheng , Gou Yulan
Published: February 2025

Background and Objectives:

Neurologic deterioration frequently occurs during the acute phase of isolated pontine infarction (IPI). However, the factors that predict early neurologic deterioration (END) are not well understood. The purpose of this study is to identify and analyze the predictors of END in individuals with IPI.

Methods:

One hundred and fifty-three patients diagnosed with acute IPI were included in this retrospective study, including 41 individuals in the END group and 112 in the non-END group. Demographic characteristics, clinical data, and imaging features were collected and compared. Logistic regression analysis was used to identify independent predictors of END in patients with IPI, and a receiver operating characteristic (ROC) curve was constructed to assess model performance.

Results:

Univariate analysis demonstrated significant differences between the two groups regarding diabetes mellitus, National Institute of Health Stroke Scale (NIHSS) score at admission, etiological classification, and infarct area, with P values less than 0.05. Multivariate binary logistic regression analysis revealed that the NIHSS score at admission and the infarct size were independent predictors of END. The combined ROC analysis of the NIHSS score at admission and the infarct area for predicting END showed a sensitivity of 85.4%, specificity of 83.0%, and an area under the curve of 0.887.

Conclusions:

Basilar artery branch disease is the primary cause of END observed in IPI. Both the NIHSS score at admission and the size of the infarct serve as significant predictors for END in IPI, and the combination of two factors provides value in predicting END and outcomes of IPI patients. Early prediction of END also can guide treatment strategies, aimed at improving patient prognosis.

Authors: Rumani Imaan , Chakrabarti Jayanta , Mandal Sandip Swarup , Gupta Souradip , Kazi Bilal , Majumder Koustav , Chakrabarti Srabani , Nanda Durga Prasad , Paul Ratnadeep
Published: February 2025

Background:

Locally advanced breast cancer, the most advanced stage of nonmetastatic breast cancer, has a substantial risk of recurrence, metastasis, and death, with a 5-year overall survival rate of approximately 57%.

Aims and Objective:

The aim of the study was to correlate and compare the clinical, radiological, and the pathological parameters in assessing the tumor response to neoadjuvant chemotherapy (NACT) and to assess rates of complete clinical and pathological response in patients of breast carcinoma being treated with NACT.

Materials and Methods:

This study was a prospective, nonrandomized, observational study. This study was conducted at Chittaranjan National Cancer Institute, Kolkata from January 2021 to January 2023 in the Department of Surgical Oncology. A total of 131 patients were included in this study.

Results:

It was found that the majority of patients (51.1%) showed a complete pathological response in the lymph nodes with the maximum number of patients belonging to the basal-like subgroup (20); it was statistically significant (P = 0.001). Higher number of patients had (57.1%) moderate residual disease (residual cancer burden [RCB1]) on final histopathology in luminal A type compared to (54.3%) luminal B type, (47.6%) basal like, and human epidermal growth receptor-2 enriched (31.0%), so correlation of molecular types and RCB was statistically significant (P < 0.001).

Conclusion:

From our study, we conclude that histopathological examination is the gold standard for assessing chemotherapeutic tumor response in breast carcinoma. Patients with molecular subtype HER2 neu and triple negative were good responders to chemotherapy. There was a reduction in the tumor size and an increase in clinically node-negative status following chemotherapy, indicating downstaging of the tumor in the majority of the patients after NACT. Neoadjuvant therapy can potentially make inoperable tumors operable. Patients who achieve a complete clinical response may not have a complete pathological response. The prognosis of the patient cannot be predicted depending on clinical response.

Authors: Poornima Komati , Mazumder Cheryl , Pal Ranita , Mandal Syamsundar , Mustafi Saunak Mitra , Nasare Vilas D.
Published: February 2025

Background:

Colorectal cancer (CRC) is a common cancer worldwide with a low reported incidence in India. It is the fourth most common cause of death due to cancer. Therefore, better prognostic or predictive markers are needed to improve survival of the disease. The present study may help to state potential role of Ki 67, β-Catenin and E cadherin in association with various clinicopathological parameters to assessing the tumor prognosis of colorectal cancer.

Aim and Objective:

The objective is to examine the clinicopathological parameters of colorectal tumors and their correlation with Ki-67, E-cadherin, and β-catenin expressions.

Material and Methods:

This is a prospective study that included surgical (colectomy) tissues and colonoscopy biopsies from 64 patients who were recruited at Chittaranjan National Cancer Institute (CNCI), Kolkata from September 2016 to February 2018. Clinico-histopathology and Immunohistochemistry for Ki-67, E-cadherin, and β-catenin were performed on the samples.

Results:

This study showed an increasing incidence of colorectal carcinoma (CRC) in young younger individuals ≤40 years. Many patients presented with advanced stage and higher grades of the tumor with the rectum (42.2%) being the most common site of the tumor. The corrected Chi-square (c2) test showed a significant association between Histopathological evaluation (HPE) and tumor grades with Ki-67, E-cadherin, and β-catenin expressions (p<0.0001).

Conclusion:

Ki67 expression in CRCs is associated with good clinical outcomes. All three markers showed an independent expression in colorectal cancer, they are strongly associated with tumor grade individually. It helps in predicting the tumor prognosis.
Clinicopathological Analysis for the Necessity of Level 2b Lymph Node Dissection in Elective Neck Dissection for Oral Squamous Cell Carcinomas – A Retrospective Institutional Study
Authors: Dey Samyadipta , Chakraborty Kaushambi , Kar Pinakpani , Kumari Dipti
Published: February 2025

Background:

Oral squamous cell carcinoma (OSCC) represents 32%–40% of all head-and-neck cancers (HNC).[1] Most of these CA metastasize locally to the cervical lymph nodes. Level 2 lies anterior to the posterior border of the sternocleidomastoid (SCM) muscle and posterior to a vertical line drawn from the posterior edge of the submandibular gland. It is further subdivided into 2a and 2b by the spinal accessory nerve (SAN). Some surgeons strongly recommend dissection of level 2b for all patients, while some do not advocate it if it is clinically negative. An injury or sacrifice of the SAN results in denervation and atrophy of the trapezius muscle leading to a condition called “Shoulder Syndrome” and subsequently affecting the quality of life of the patient. Against this background, it remains a matter of debate whether level 2b dissection should be done.

Aims and Objectives:

We performed a postoperative histopathological analysis of tumour size, depth of invasion (DOI), and nodal metastasis and attempted to know whether level 2b dissection can be avoided in early as well as advanced oral squamous cell cancers (OSCC) or not.

Materials and Methods:

A retrospective analysis of 50 patients with OSCC patient, after curative surgery with elective neck dissection, was conducted to see the correlation and incidence of level IIB positivity with demographic factors, tumor subsite, pathological staging, DOI, and corresponding level 2a status.

Results:

In our study, only 36% are positive for level 2b lymph node. Therefore, retrospectively, we have concluded that only in 36% of cases, level 2b neck dissection was necessary. In the rest 64% of the cases, level 2b lymph node dissection could have been avoided. For tumors, a pathological staging of pT4aN2b and pT4N3b had the highest level 2b positivity, while Level 2b positivity was nil in early-stage oral squamous cell carcinomas with N0 neck. Tumors having DOI of 14 and 15 mm showed the highest level of 2b node positivity with a mean of 17.78 mm and an SD of 11.28 mm. As per oral subsite, buccal mucosa, lower alveolus, and tongue showed the highest level 2b positivity, while carcinoma of the lip and CA retromolar trigone showed the lowest level 2b positivity.

Conclusion:

As per our results, many patients could have been spared from inadvertent SAN injury and shoulder dysfunction during neck dissection. Pertaining to our results, it can be safely concluded that level 2b neck dissection may be avoided in early T1 and T2 tumors with N0 neck, although further studies are required on preoperative clinico-radiological correlation with postoperative histopathological analysis.

Published: February 2025

Background:

Vitamin D, acting via the vitamin D receptor (VDR), has antitumor effects through inhibition of proliferation and angiogenesis. Some previous studies showed an inverse correlation between VDR expression and the progression of cutaneous melanoma; however, other studies did not find this correlation, suggesting a probable ethnic/geographic effect. We aimed to evaluate the expression pattern of VDR in cases of cutaneous melanoma in a Middle Eastern country, Egypt.

Materials and Methods:

A total of 42 paraffin blocks and slides from 42 patients were retrieved from the pathology archives of our institution and immunohistochemically stained against VDR. The density and pattern of VDR immunostaining in positively stained cases were analyzed and compared with various demographic, clinical, and histological parameters of Egyptian patients who underwent surgical excision for cutaneous melanoma between 2017 and 2022.

Results:

A total of 37 cases (88.1%) expressed VDR, showing no significant correlation with the tumor site, size, metastasis, or invasion. However, a statistically significant difference was observed between nuclear and cytoplasmic VDR expression. Nuclear expression was associated with unfavorable tumor characteristics, including increased Breslow thickness, Clark level, and vascular invasion.

Conclusion:

VDR expression can serve as a prognostic marker in the histopathological evaluation of cutaneous melanoma; however, the utility of nuclear versus cytoplasmic expression of VDR should be more studied in the future research incorporating genetic analysis. Our findings, in contrast to several previous studies but in agreement with a few, suggest an association between nuclear staining and tumor progression.

Authors: B.S Gopika , Rajeshwari
Published: February 2025

Static VAR compensators (SVC), power rectifiers, and thyristor converters are examples of power electronics components that significantly contribute to harmonics in a range of applications. The use of power electronic converters, especially DC/AC PWM inverters, has been expanding in the industry due to the advantages they provide, including reduced energy consumption, improved system efficiency, higher-quality products, simplicity of maintenance, and more. One of the most basic and well-known topologies for multilevel inverters is cascaded H-Bridge (CHB) MLI. A KY boost converter with seven-level inverters is suggested in this study. A Matlab simulation is used to evaluate the suggested work. According to the simulation findings, the output voltage climbed from 121V to 155V, the motor speed increased from 940 rpm to 1050 rpm, the motor torque increased from 0.92 N/m to 1.80 N/m, and the output current THD decreased from 31.2% to 19.01% when a KY boost converter with a seven-level inverter was used. According to the simulation results, the conventional boost converter with a five-level inverter system performs worse than the suggested KY boost converter with seven-level inverters.

Increasing interest in healthy food among the population raises concerns about heavy metals in fruit and their impact on public health. To assess this issue, this study presents a comparative analysis of digestion methods for quantifying heavy metals in plum orchards managed under conventional and ecological practices in the “Adamachi” Farm district of Iasi University of Life Sciences (IULS). We evaluated and optimised two wet digestion methods - in an open system and microwave-assisted - to determine the concentrations of heavy metals, such as copper (Cu), zinc (Zn), nickel (Ni), lead (Pb), and cadmium (Cd), which pose environmental and health risks. The metal concentrations were measured using an atomic absorption spectrophotometer, according to standard methods. Microwave-assisted digestion was more efficient and faster than the conventional method (in an open system). The ecologically managed orchards showed a lower heavy metal content overall, with the exception of Cu levels, due to the Cu-based treatments. By determining the estimated daily intake (EDI), target hazard quotient (THQ), and hazard index (HI) for both children and adults, the potential health risks from heavy metals were determined. There were no related associated risks to human health (THQ and HI < 1), and the accumulated metals in plum fruit samples showed that the EDI values followed the descending order of Cu > Zn > Ni > Pb > Cd. The analysis revealed non-significant differences for most data obtained after processing using the two methods. These results highlight the importance of selecting the optimal digestion methods for heavy metal analysis in plums and sustainable agricultural practices to safeguard the environment and consumer health from heavy metal contamination.

This study reviews the increasing technological cooperation between China and Pakistan with a focus on influence in their cooperation within 5G, AI, and cybersecurity domains and examines their implications against the background of global tech competition. It will underscore, through systematic literature review, both opportunities and challenges presented by such cooperation. China's technology investment, especially in companies such as Huawei, has significantly pushed the digitization of the infrastructure of the country, which improves the telecommunication network of that country and gives it a prime position in terms of being among the first of the world with 5G and AI technologies. These developments are considered significant for Pakistan in terms of accelerating economic growth of the country. However, this review does depict some major concerns over the issue of digital sovereignty and national security risks associated with this investment. Increasing dependence of Pakistan on the Chinese technology could make it prone to potential security threats, which might include breaches in data security, cyber-attacks, and risks of surveillance. All these threats can undermine Pakistan's sovereignty and control over its critical infrastructure. Moreover, geopolitical effects of this relationship are widespread, as close alliance with China will impact the relation of Pakistan with Western powers and regional neighbors especially India. Diversifying and intensifying the competition at the world level of technology is faced by Pakistan when it balances apparent economic advantages from Chinese investment against the risk of long-term dependence on a single technological partner. The conclusion is that Sino-Pakistani technological cooperation, although offering substantial developmental opportunities, needs careful strategic management to mitigate security, sovereignty, and geopolitical dynamics-related risks. The future studies should include the directions about how Pakistan should diversify its technological partnerships, increase a more independent technological ecosystem, and better secure national interests as the competitive advantage in the global technological landscape continues to expand.

This study examines the effectiveness of various alternative statistical approaches in testing the null hypothesis's significance to improve marketing research's reliability. Conventional methods such as p-value are often misunderstood and have limitations in interpreting the results of the analysis. Therefore, this study compares several alternative approaches, including Bayesian inference, bootstrap resampling, and false discovery rate, to improve the validity and repeatability of marketing research results. By using a simulation-based quantitative approach and a survey of marketing academics and practitioners, the findings of this study show that alternative methods can provide more informative results than conventional techniques. The implications of this study contribute to strengthening marketing research methodologies to be more accurate and reliable.
Using time series methods to analyse the COVID-19 pandemic's impact on food and beverage sales trends in South Africa.
Authors: Makoni Tendai , Chikobvu Delson
Published: February 2025

Research Aims: Food is essential to human survival, but the COVID-19 pandemic posed significant risks to the food value chain in many countries, including South Africa (SA). The pandemic disrupted the food supply chain, creating an unprecedented challenge for the SA food and beverage industry. This study aims to use time series methods to investigate and understand how the COVID-19 pandemic has affected food and beverage sales trends in SA.
Design/methodology/approach: The monthly food and beverage sales data is analysed using the Box-Jenkins methodology.
Research Findings: A SARIMA(0,1,1)(1,1,1)12 model is confirmed as the best model based on the Akaike Information Criterion. The Root Mean Square Error and Mean Absolute Error metrics support the model's forecasting performance. The findings reveal that the COVID-19 pandemic harmed the food and beverage industry, with sales not yet fully recovered to pre-pandemic levels. This highlights the severity of the pandemic's effects on South Africa’s food and beverage industry. However, there is a positive sign of recovery, with future food and beverage sales expected to rise. This recovery is driven by the adoption of digital technologies by many food and beverage companies, enabling them to adjust to the evolving circumstances. Businesses adopting digital solutions like online ordering, delivery platforms, and mobile marketing witness a more robust recovery. Such investments aid food and beverage companies to broaden their clientele, improve operations, and adapt to changing consumer demands post-pandemic. Expanding online ordering, subscription-based delivery, contactless payments, and catering to dietary needs attracts new customers and enhances brand reputation.
