PROCESS OF CREATING AND COMPARING 4D MODELS OF RHENISH CASTLES IN DIFFERENT MODELING ENVIRONMENTS
Authors: Koehl M. , Heitz J. E. , Rigaud D. , Guillemin S.
Published: February 2024

Abstract. Alsace is renowned for its rich castle heritage. With more than 500 listed castles, it is one of Europe's most densely fortified areas (Châteaux forts Alsace, 2013). Some of them date back to the 11th century, and most of them are in ruins. It was against this backdrop that these studies were carried out as part of the Châteaux Rhénans - Burgen am Oberrhein project, funded by the European Interreg VI programme. More specifically, within the animation and promotion strands carried out by INSA Strasbourg and Tourismus Südliche Weinstraße. These actions focus on the digitisation and digital promotion of the Rhine castral heritage. Two projects are described and compared in this paper. The Oedenbourg castle is a little-known site. Tucked away behind its famous neighbour (Haut-Koenigsbourg castle, Orschwiller, Alsace, France), this ruined remains from the 15th century houses a Gothic dwelling dating from the 13th century. The Oedenbourg, with its architectural elements from different historical periods, was now the subject of new excavations to shed light on its history. The ruins of Wasenbourg castle, which dominates the commune of Niederbronn-les-Bains in Alsace (France), are the second site to be studied. Historians agree that it was built in the 13th century, but the precise date is around 1272–1275. In 1592, the castle is mentioned as being in ruins. This paper presents the different processes undertaken for the digitisation, 3D modelling and 4D restitution of the two sites, using two different modellers, namely Autodesk Maya for the Oedenbourg and Blender for the Wasenbourg.
BUILT-IN LENS CORRECTION PROFILES IN LOW-COST CAMERAS: AN ISSUE FOR PHOTOGRAMMETRIC APPLICATIONS?
Authors: Perfetti L. , Fassi F. , Vassena G. P. M.
Published: February 2024

Abstract. Photogrammetric applications nowadays envisage the use of more and more low-cost cameras such as those equipped on commercial UAV platforms. Typically, these low-grade cameras suffer from extreme radial distortion and strong vignetting among other defects. This, initiated a trend among the low-cost cameras’ manufacturers to try to hide the camera defects by applying software pre-corrections to the images. These Built-In Correction Profiles gets applied to both the JPG files, directly in-camera, and usually to the raw files as well, through the opcode functions of the DNG standard. In this paper we rise this issue that is still under-reported in the literature and further assess the accuracy implication of applying or discarding the Built-In Correction Profile in the scenario of UAV mapping. We tested the commercial UAV DJI Phantom 4 Pro v2 in a calibration environment and a field test to compare the performance of pre-corrected versus uncorrected images. In our tests, processing the original uncorrected images led to improved IO calibration and reduced bowing effect in the field test.
AN INTEGRATED HBIM-GIS DIGITAL ENVIRONMENT FOR HERITAGE PRESERVATION AND ENHANCEMENT IN THE INNER ITALIAN TERRITORY
Authors: Pozzoni L. , Barazzetti L. , Cuca B. , Oteri A. M.
Published: February 2024

Abstract. Depopulation in Italy is causing the marginalization of several inner territories and municipalities, with consequences for the preservation of different levels of heritage. The Italian National Strategy for Inner Areas (SNAI) aims to address these issues, but in some cases, the policies undertaken are not effective enough to improve development. In this context, the integration of Historic Building Information Modeling (HBIM) and Geographic Information System (GIS), as a potential solution in the enhancement of knowledge, information, and project management, could be an important resource to lean on. To investigate this aspect, the municipality of Dosso del Liro in the Northern part of Lake Como (Lombardy) has been chosen as a case study, based on its marginality and its territorial variety. The research methodology involves a combination of field data collection, bibliographical and archival investigations, database research, and digital recording of heritage, with the purpose of modelling and analyzing the territorial context on different aspects and at different scales. Precisely, multi-disciplinarity and multi-scalarity (but also multi-temporality) are the key points for the HBIM-GIS modelling. Thus, trying to integrate and interpret in this innovative way the information acquired, the research aims to investigate the possibility of improvement for the creation of effective strategies and projects in the Inner Areas. The idea, in fact, is that with an increased knowledge and awareness of the heritage, the requirements for the design phase will be better in sight, and the quality of the intervention will be increased.
COMBINING IMAGE AND POINT CLOUD SEGMENTATION TO IMPROVE HERITAGE UNDERSTANDING
Authors: Bassier M. , Mazzacca G. , Battisti R. , Malek S. , Remondino F.
Published: February 2024

Abstract. Current 2D and 3D semantic segmentation frameworks are developed and trained on specific benchmark datasets, often rich of synthetic data, and when they are applied to complex and real-world heritage scenarios they offer much lower accuracy than expected. In this work, we present and demonstrate an early and late fusion of methods for semantic segmentation in cultural heritage applications. We rely on image datasets, point clouds and BIM models. The early fusion utilizes multi-view rendering to generate RGBD imagery of the scene. In contrast, the late fusion approach merges image-based segmentation with a Point Transformer applied to point clouds. Two scenarios are considered and inference results show that predictions are primarily influenced by whether the scene has a predominantly geometric or texture-based signature, underscoring the necessity of fusion methods.
3D PHOTOGRAMMETRIC MODELS FROM HDR IMAGES: THE CASE STUDY OF THE FONTANONE VISCONTEO IN BERGAMO
Authors: Cardaci A. , Versaci A. , Azzola P.
Published: February 2024

Abstract. The world is a complex subject whose dynamic range between dark and light cannot be captured by digital cameras. The range of light that can be measured and recorded by a single exposure, is too limited and adapted only for the average light values of the scene. This paper focuses on the integrated surveys activities undertaken on the Fontanone Visconteo in Bergamo, to improve its knowledge and assess its conservation status. The specific lighting conditions of the environments (in particular, of the tank) have given the perfect opportunity for testing solutions aimed at the reconstruction of the clouds from different HDR processing to highlight the diverse surfaces’ treatment and understand the sequence of build actions. The purpose is to provide a thought-provoking discussion about the delicate issue of high-quality work that can be obtained from HDR images (12 bit) and RAW files such as TIF, DNG, and JPG (8 bit).
Antibiotic prophylaxis before tissue biopsy has no effect on culture results in presumed aseptic revision total hip arthroplasty
Authors: De Groot Jesse D. , Brokelman Roy G. B. , Fransen Bas L. , Jiya Tim U. , Pakvis Dean F. M.
Published: February 2024

Abstract. Background: Antibiotic prophylaxis (AP) is considered to be the gold standard for revision total hip arthroplasty (R-THA) due to the high incidence of prosthetic joint infection (PJI). To diagnose PJI, intraoperative tissue biopsies for culture are of particular importance. However, antibiotic interference could theoretically lead to less reliable culture results. Currently, there is no consensus on whether AP should be administered before or after tissue biopsy. In this study, we aimed to investigate the effect of AP timing on culture results and PJI rates in presumed aseptic R-THA. Methods: A retrospective single-center cohort study among 490 patients was performed; 61 patients received AP pre-incision, and 429 patients received AP post-biopsy. At least three intraoperative tissues were sampled for each patient and cultured for a minimum of 2 weeks. Minimum follow-up was 6 months. Epidemiological and clinical data (including culture results and incidence of PJI during follow-up) were gathered and analyzed. Results: Positive (4.9 % vs. 5.4 %, p=0.89) and contaminated culture results (23.0 % vs. 22.6 %, p=0.95) were not significantly different between pre-incisional and post-biopsy AP administration. Post-operative PJI incidence during follow-up was 1.6 % and 3.0 %, respectively. This difference was not statistically significant (p=0.54). Conclusion: Pre-incisional AP administration does not yield fewer culture results compared to post-biopsy AP administration. Although statistically not significant, PJI during follow-up was almost twice as high when AP was withheld until after tissue biopsy. Other literature also supports the additional protective benefit of pre-incisional AP. Therefore, we believe pre-incisional AP administration is preferable for presumed aseptic R-THA.

Authors: Martín Sandra Gisela , Schmidt Analía
Published: February 2024

Objetivo. El presente trabajo tiene por finalidad principal identificar y describir las prácticas de gestión de datos abiertos de investigación en las bibliotecas de las universidades privadas argentinas. Se plantean como objetivos específicos: identificar las políticas de acceso abierto y/o de datos de investigación; indagar sobre el grado de implementación de datos de investigación; establecer qué tipo de datos de investigación que se están gestionando; conocer el nivel de participación y compromiso de las bibliotecas en la infraestructura de gestión de datos de investigación en sus instituciones; establecer si las bibliotecas se vinculan con las áreas de investigación de sus respectivas universidades; determinar qué tipo de servicios de datos de investigación ofrecen las bibliotecas; conocer si las bibliotecas realizan acciones de concientización, capacitación o asesoramiento en datos de investigación; determinar si las bibliotecas cuentan con personal capacitado, con competencias y conocimientos en la temática de datos de investigación; indagar sobre la percepción de los directores de bibliotecas respecto a las demandas de gestión de datos de investigación por parte de las bibliotecas, y por último, investigar si las bibliotecas tienen planes a futuro sobre servicios de gestión de datos.
Método. Investigación descriptiva que utiliza como técnicas para la recogida de datos la observación directa de las páginas web universitarias y/o repositorios institucionales, y un cuestionario semiestructurado con preguntas abiertas y cerradas destinado a los directores de bibliotecas.
Resultados. El grado de implementación de datos de investigación en las universidades privadas argentinas es incipiente, ya que, a pesar de contar con repositorios institucionales de publicaciones, se plantea en forma muy novedosa el hecho de desarrollar un repositorio de datos de investigación o realizar acuerdos de colaboración con algún repositorio temático o interinstitucional. De acuerdo a lo investigado se puede afirmar que la gestión de datos de investigación es ínfima, ya que solo una institución cuenta con un único registro de conjunto de datos de investigación referido a un cuaderno de trabajo.
Conclusiones. Las bibliotecas de universidades privadas en Argentina, teniendo en cuenta su contexto particular, tienen un gran reto en los próximos años para seguir adecuándose a la legislación nacional de acceso abierto. El trabajo conjunto con otras bibliotecas, con investigadores y otras instituciones científico-técnicas del país seguramente ayudará a que la gestión de los datos de investigación se consolide.

Authors: Alkhwaji Abdusalam I. , Muamar M. Ben Is  , Hitem A. Aswihli
Published: February 2024

This research paper presents a procedure to estimate parameters for the modified Taylor equation using experimental measurement. The end-of-life times for each laboratory test were recorded well. The tool life has been measured by observing an abnormal change in the observed pitch of a sound from the cutting tool. The objective of this research is to understand the wear mechanisms of the insert carbide tool for different speed machining under dry condition using longitudinal turning process. The tool life equation obtained by linearizing the expanded Taylor tool life equation and solving a linear system of equations using linear least squares. In this study, both the experimental data and analytical solution show reasonable fit. The estimated tool life model simulates the measured end of tool life using the sound inspection method. An additional analysis to confirm effects of each cutting parameter on the tool life have been presented. Estimating the Tool life (TL) model using nonlinear least squares could give more accurate results which is going to be considered in the future study. The significance of this study is to save resources in the manufacturing industry by avoiding estimating tool life during turning process. Since that cause delay in the production time and waste of resources.

La iniciación literaria de Antonio Cillóniz. Claves en la conformación de una poética
Authors: Fernández Teodosio
Published: February 2024

Se analizan los poemarios Verso vulgar (1967) y Después de caminar cierto tiempo hacia el este (1971), los primeros de Antonio Cillóniz, con el fin de fijar el punto de partida de una poética que desde el principio conjugó inquietudes formales con otras de carácter político y social, a las que se presta la atención requerida para la comprensión y la valoración adecuadas de aquellos poemas de prematura madurez. Esa poética impulsará desde entonces el desarrollo de una obra de calidad indudable, reelaborada una y otra vez a la vez que la enriquecían poemas y poemarios nuevos, hasta conformar un conjunto tan relevante como alejado de la atención de la crítica, cuyas carencias este artículo pretende atenuar.

Un brieve trattato dell’eccellentia delle donne e Una brieve essortatione a gli huomini: ulteriore analisi delle due opere cinquecestesche
Authors: Bucuré Miriam
Published: February 2024

Nel 1545, dalla tipografia di Damiano de Turlini a Brescia, usciva un volume contenente due operette: la prima intitolata Un brieve trattato dell’eccellentia delle donne composta dal filosofo lombardo Vincenzo Maggi; la seconda, anonima, con il titolo: Una brieve essortatione a gli huomini. Vincenzo Maggi, con un trattato –come lui stesso dichiara– breve e semplice, confuta il disprezzo verso il genere femminile imperante nella sua epoca, spinto dalla necessità di ritrovare la verità. Il tutto senza screditare né le tesi avverse né i maschi; anzi, con l’intenzione di convincere costoro ad apprezzare ancor di più le donne e riconoscerne i superiori meriti. L’autore anonimo, invece, pretende smentire le affermazioni del filosofo lombardo esortando gli uomini all’azione, e si dichiara intimorito dall’idea che le donne possano prendere il sopravvento. È nostra intenzione analizzare le due opere presentandone le argomentazioni e i modi in cui esse vengono esposte, nonché offrire una breve biografia di Vincenzo Maggi oltre ad affrontare l’argomento della paternità della seconda opera.
Hacia una concepción de la violencia en José Carlos Mariátegui
Authors: Mera Olivares Diego
Published: February 2024

. Se problematiza la comprensión de la violencia en la obra del pensador peruano José Carlos Mariátegui (1894-1930). A partir de la premisa que tal comprensión articula concepciones y concreciones de la violencia, se reconocen, primero, dos concepciones distintas: como-medio y como-reacción. En cuanto a las concreciones se argumentará que esta se encuentra permeada por una nueva agencia política, por el concepto de mito de Georges Sorel, que tendrá sobre ella unos efectos más formales que prácticos, y por las divergencias del panorama social peruano respecto al clima social internacional –donde las condiciones de una situación revolucionaria propuestas por Lenin resultarán claves para entender la postura de Mariátegui–.

El presente trabajo de investigación tiene como objeto el estudio de la legislación penal en la República de Colombia desde 1890 hasta la actualidad con la ley 599 de 2000, este último conocido como el vigente Código Penal. Lo anterior, conforme a la siguiente pregunta problémica ¿se ha dado un desarrollo oportuno de la legislación penal colombiana que otorgue soluciones fehacientes a las necesidades de una política criminal sólida desde sus inicios hasta la actualidad?
Con ello, se pretende analizar las diversas escuelas que han influido en los legisladores a la promulgación y tipificación de los delitos y sus penas en el marco jurídico penal colombiano. Se destaca ante todo, el análisis que a lo largo del desarrollo del ordenamiento jurídico colombiano abarca el contexto constitucional, doctrinal y jurisprudencial, los cuales, han logrado evidenciar el carácter de un óptimo “derecho penal” a lo largo del contexto histórico del país en mención. Se destaca así, la gran influencia de las Escuelas Clásica, Positivista y Finalista, que a hoy han venido a establecerse con fuerza en Colombia a lo largo de su codificación, desde 1980 hasta la actual ley 599 del año 2000.
The Idea of Communism and the Communism of the Idea
Authors: Medina Polo Simone A.
Published: February 2024

This essay articulates a double helix at work in Badiou’s thought on politics as a condition of philosophy and philosophy as such by focusing on what Badiou calls “the Idea of communism” and we will call “the communism of the Idea.” The former refers to communism as an Idea par excellence, while the latter concerns the Idea as a philosophical communism. The first section of the essay unpacks the Idea of communism as a composite interaction of politics, history, and subjectivity insofar as each of these elements cannot be taken in themselves. Contrary to post-ideology, Badiou condemns the claim that we should live without an ideological framework insofar as this asks us to live without an Idea. The second section will focus on the communism of the Idea as the result of Badiou’s broader philosophical project and its major Platonic gestures. Badiou’s broader concerns pertain to the commitment to live with an Idea as finite, infinite, and transfinite to the endpoint that philosophy itself is characterized to be destined for communism. The crux that anyone can become a serious philosopher if, to paraphrase Diotima in Plato’s Symposium, they gracefully lend themselves to the process of truths as their fundamental commitment.

The article discusses the results of heat and power and exergy calculations of the possibilities of new and existing technologies to reduce carbon dioxide emissions and coke consumption, increase pig iron production by injecting hydrogen and hydrogen-containing fuel additives (coke and natural gas) into the furnace, using metal additives, increasing the blast temperature, heat losses, and improving gas distribution in the blast furnace. The calculations were performed using a mathematical model of the complete energy balance of blast furnace smelting developed at the Iron and Steel Institute of Z. I. Nekrasov National Academy of Sciences of Ukraine, and the impact of the potential of new and existing technologies on reducing CO2 emissions and technical and economic indicators of blast furnace smelting was assessed when the consumption of pulverized coal, hydrogen and hydrogen-containing fuel additives and their combinations in a wide range was changed. The limit values for the injection of hydrogen and hydrogen-containing fuel additives into the blast furnace horn have been determined, which are determined by the following factors: the degree of direct reduction of iron, theoretical combustion temperature, the presence of industrial oxygen, and the temperature of the furnace gas. The study results showed that CO2 emissions in blast furnace production can be reduced by 25-30% by making changes to blast furnace technology and depend on investments, the raw material and energy base of the steelmaker, and the level of existing blast furnace technology. The paper considers the impact of low-cost measures to increase the blast temperature, use of clean metal additives, reduce heat losses, and improve gas distribution in the blast furnace on the reduction of carbon dioxide emissions and technical and economic indicators of blast furnace smelting. The results can be useful for determining the economic feasibility of a particular measure to reduce CO2 emissions in blast furnace production.

The article discusses the trends and classification of blast furnace blowers over the past 100 years. The development of blower technology is divided into 3 periods: The 1st period lasted until the end of the 30s of the XX century, characterized by a lack of scientific knowledge, mysticism and based on previous experience; the 2nd period - until the early 70s, when the "traditional" blower technology was mastered with one problem - difficulties with opening the first releases and simultaneous overheating of the top; the 3rd period continues today, it includes the development of new methods for intensifying heat transfer during blowing and scientific generalization of blower techniques. The main tasks of blowdown are to bring the blast furnace back to normal operation in a short time, in compliance with safety rules, without significant costs, and to preserve the blast furnace and auxiliary equipment for long-term productive operation. These tasks are closely linked to the design features of blast furnaces, including the cooling system, lining type and furnace size, which have steadily increased from less than 500 m3 to 5,600 m3. The complexity of understanding the processes of heating the charge column during the blowing period with the formation of a gas flow and a cohesion zone in it is the reason for numerous discussions about rational blowing methods: methods for calculating and placing layers of the blast furnace charge, the use of various hot blast additives (nitrogen, natural, blast furnace or coke oven gas, oxygen, steam, etc.), the rate of increase in hot blast flow and its temperature, the trend of pressure drop along the height of the charge column. The use of wood in the blast charge, the installation of constrictor rings in air tuyeres or the closure of a part of the tuyeres for blowing are discussed. Recommendations for blast furnace blowers are given. A comparison of "traditional" blowing with "progressive" blowing and blowing with nitrogen developed at the Iron and Steel Institute National Academy of Sciences of Ukraine are presented.

The main way to improve the quality characteristics of the steel is a properly selected heat treatment, the purpose of which is to create a structure that would meet the requirements of the manufacturer. The size of the austenite grain in the steel depends significantly on the heating temperature during heat treatment, which in turn affects the final structure of the steel and mechanical properties after treatment. The experimental chromium molybdenum vanadium steel 31CrMoV9 (EN 10085:2001) was heated to temperatures in the range of 850...1050°C and cooled in water and air. The structure formation of the Cr-Mo-V steel after heating to different temperatures, quenching and tempering, consists of tempered martensite (including residual austenite) and alloyed carbides, and after normalization - bainite and martensite with different ratios. As the normalization temperature increases, the total area occupied by martensite increases without changing its morphology. The increase in the heating temperature leads to an increase in the amount of martensite from 10% at 850°С to 50% at 1050°С, correspondingly, the microhardness of the steel increases, shown by research. With an increase in the tempering temperature, the average microhardness of steel decreases. The change in microhardness is probably associated with an increase in the amount of the residual austenite and the dissolution of alloyed carbides. Detected that with an increase in the heating temperature, the increase in the initial austenite grain led to the coarsening of martensite needles. The effect of the increasing the austenization temperature on the change in the structure of the Cr-Mo-V steel was shown during investigations. Detected that the temperature of the austenization affects the cooling rate. To obtain more detailed results of this effect, it is necessary to conduct additional investigations of the kinetics of the transformations in the Cr-Mo-V steel upon cooling from different temperatures. The obtained results make it possible to tentatively predict the final structure of the Cr-Mo-V steel after various modes of the heat treatment. Heating should be carried out at a temperature of 850ºС, which will additionally lead to resource saving to get a uniform structure in the Cr-Mo-V steel.

Treatment of tuberculosis requires long-term use of antituberculosis drugs with a high risk of side effects. In recent decades, along with the frequent and detailed side effects (gastrointestinal symptoms, hepatotoxicity, neurotoxicity, allergic reactions), hematological and coagulation disorders have been described when taking antituberculosis drugs. Their main manifestations can be: iron deficiency anemia, hemolytic anemia, megaloblastic and sideroblastic anemia, thrombocytopenia, thrombocytopenic purpura, leukopenia, eosinophilia, agranulocytosis, deep vein thrombosis, thromboembolism, disseminated intravenous coagulopathy, etc. Although these side effects are rare, they require special attention because they can appear more frequently in the case of intermittent or interrupted treatment and present diagnostic difficulties.
Xanthogranulomatous appendicitis
Authors: Sor Elina , Mishin Igor
Published: February 2024

Xanthogranulomatous inflammation is characterized histologically by a collection of lipid-laden macrophages admixed with lymphocytes, plasma cells, neutrophils, and often multinucleated giant cells with or without cholesterol clefts, that develops most often in the kidneys and gallbladder. But the involvement of vermiform appendix in the disease process is quite rare with only few cases are reported in literature. Xanthogranulomatous appendicitis is usually identified retrospectively on surgical pathology, that is associated with significant diagnostic and therapeutic dilemmas due to its variable presentation.

Background: Plants, herbs, and ethnobotanicals have been utilized for health promotion and disease treatment since the dawn of time and are still widely employed today. The immense demand and potential health advantages of herbal medicines balance out the enormous research demands. There is a need for research on the quality, safety, molecular effects, and therapeutic efficacy of the many common herbs. Aim and Objective: The aim of the study is to prepare Silver Nanoparticles using fruit extract of Sapindus Mukorossi by green synthesis technique, and to develop new derivatives of antibiotic due to high resistance from conventional antibiotics. Method: The Sapindus mukorossi fruit extract AgNPs was prepared by green synthesis technique. Formulation of silver nanoparticles using water/methanol reetha fruit extract was carried out by addition of fruit extract to a reaction mixture containing 1M AgNO3 and 0.625% ammonia solution and left for 48hrs in dark place with regular interval exposing to light. The prepared silver nanoparticles were characterized using SEM, FTIR and XRD studies. Result: The synthesized nanoparticles found to be spherical and crystalline in nature. The FTIR measurements identifies the functional groups attributed for silver ions reduction and AgNPs stabilization. The synthesized yield was 58.34%, 77.46%, 49.67% and 69.32% respectively. The methanol extract shows greater activity than Aqueous extract against E.coli and Streptococcus aureus. Conclusion: The Phyto-based drugs exhibit good medicinal properties with less side-effects as compare to synthetic based drugs. The reetha is known for its many properties such as foaming agent, antibacterial activity etc. The idea was to develop the new antibacterial drugs as the humans getting resistant to the antibacterial drugs. The antibacterial results show that the prepared AgNPs were effective in inhibiting growth of both S. aureus and E. coli bacteria, and hence they could be potential applications in bio-related field.

This study was conducted to find an efficient and inexpensive wastewater treatment system in poor regions and countries. For this purpose, two filtration systems were used to treat wastewater from a WWTP in Morocco, the first one is the intermittent sand filter (ISF) based on fine sand, and the second one is called the modified infiltration percolation (MIP) based on activated carbon. Physico-chemical and bacteriological analyses were carried out before and after passing the water through the filters. The results showed a significant decrease in the physicochemical parameters such as Suspended matter (SM) with an abatement rate of 99.6% for ISF and 99.4% for MIP, Chemical oxygen demand (COD) with an abatement rate of 17.7% for ISF and 55% for MIP, Biochemical oxygen demand (BOD5) with an abatement rate of 7.14% for the first filter, and a significant decrease with an abatement rate of 100% by MIP. These two filters decreased the concentration of fecal coliforms with a respective removal rate of 98.2% for ISF and 99% for MIP, except that this concentration exceeds the standards. The physicochemical analyses were within the norms, and the filtration systems showed an important efficiency, contrary to the bacterial load of coliforms which exceeded the standards. To this effect, another treatment is necessary to reduce the bacterial load of the wastewater.

Colchicum luteum (Liliaceae) belongs to genus Colchicum. The Liliaceae family consists of 280 genera and 4000 species, with diverse geographical locations. In the Kashmir valley, they are widely distributed. Colchicum luteum is a perennial plant with corms and starchy rhizomes. This drug holds a prime position in the Unani system of medicine due to presence of alkaloid colchicine, which is found to be effective in arthritis, gout, rheumatism, and used as a carminative, laxative, and aphrodisiac. Its hydro-alcoholic extract was screened for the presence of several phytoconstituents using preliminary phytochemical methods. The microscopy of the Colchicum luteum corm revealed the presence of Fragment of Vessels with Spiral and Annular Thickening, Parenchyma and Part of a Spirally Thickened Vessel, Calcium-Oxalate Crystal, Starch-Granule and Single-Fibre. Proximate analysis revealed that Colchicum luteum corm dry plant powder has a 2.6% Total Ash Value, 1.0% Acid Insoluble Ash Value, and 1.8% Water Soluble Ash Value. 10.6 percent was determined to be the loss on drying. Post treatment with various chemical agents, fluorescence examination of the powdered plant material was performed under UV light at 254 nm and visible light. The current study showed the microscopical characters, the preliminary phytochemical screening and the proximate analysis of the Colchicum luteum corm. Information collected from such studies can be used as benchmark in the quality control of this plant as herbal medicine for treatment of various diseases.
