The Applegate-Kennedy system is highlighted as the most commonly used today for its simplicity.
This document discusses removable partial dentures (RPDs). It defines RPDs as any prosthesis that replaces some teeth in a partially dentate arch and can be removed by the patient. There are two main types of RPDs: acrylic partial dentures made of acrylic and clasp, and cast partial dentures made of cast metal and acrylic. Kennedy's classification system is described which categorizes different types of edentulous arches. Applegate rules provide additional guidelines for Kennedy's classification. Examples of terminology used in relation to RPDs are also given such as abutment, retainer, and distal extension base. Social media links are provided at the end for additional dental education resources.
Maxillary major connectors are an important component of removable partial dentures that join the denture bases on each side of the dental arch. There are several types of maxillary major connectors including single palatal straps, combination anterior and posterior palatal straps, palatal plates, U-shaped connectors, single palatal bars, and anterior-posterior palatal bars. The ideal major connector is rigid, protects soft tissues, provides indirect retention, promotes patient comfort, and is self-cleansing. Proper design of the major connector involves outlining the denture base areas, non-bearing tissues, and connector areas on the diagnostic cast.
This document discusses removable partial dentures. It begins by defining different types of patients - those who are dentulous (have natural teeth), edentulous (have no natural teeth), or partially edentulous (missing some teeth). For partially edentulous patients, removable partial dentures are discussed as replacements for missing teeth.

02 classification and indications of rpdAmal Kaddah
This document discusses removable partial dentures. It begins by outlining the indications for removable partial dentures, including when the abutment teeth are not suitable for fixed bridges due to periodontal issues, extensive bone loss, or economic considerations. It then covers classifications for partially edentulous arches, including whether the denture is tooth-borne, tissue-borne, or a combination. Kennedy's classification system categorizes cases based on the location of edentulous spans. The document concludes with the component parts of removable partial dentures.
Kennedy's classification system from 1923 is the most widely used for classifying partially edentulous arches. It divides arches into four main classes based on the relationship of edentulous spaces to remaining teeth: Class I has bilateral posterior spaces, Class II has unilateral posterior spaces, Class III has a unilateral space with teeth anterior and posterior, and Class IV has a single anterior space. While simple, it does not consider factors like abutment teeth. Other systems provide more details but are more complex. Overall, Kennedy's classification allows clear communication of the dental condition and guides treatment planning.
Fixed partial dentures transmit forces through the abutments to the periodontium. Failures are due to poor engineering, the use of improper materials, inadequate tooth preparation, and faulty fabrication. Of particular concern to prosthodontist is the selection of teeth for abutments. They must recognize the forces developed by the oral mechanism, and resistance.
Successful selection of abutments for fixed partial dentures requires sensitive diagnostic ability. Thorough knowledge of anatomy, ceramics, the chemistry and physics of dental materials, metallurgy, Periodontics, phonetics, physiology, radiology and the mechanics of oral function is fundamental.
This document discusses the Kennedy classification system for partially edentulous arches. The classification system facilitates treatment decisions by categorizing cases based on location and extent of edentulous areas, condition of abutment teeth, occlusal characteristics, and residual ridge characteristics. The system includes four main classes that describe different edentulous area locations. It is designed to allow dentists and labs to easily visualize case types, differentiate between tooth-supported and tissue-supported dentures, and formulate treatment plans. The classification also establishes basic design principles and anticipates potential difficulties for different designs.

This document discusses removable prosthodontics, which involves replacing missing teeth with removable partial dentures or full dentures. Removable partial dentures replace some missing teeth, while full dentures replace all teeth in one dental arch. The document outlines factors that influence prosthesis choice, components and construction of partial and full dentures, and sequencing of appointments for fabrication and maintenance.
There are two main types of denture bases: metal and plastic/acrylic. A denture base attaches prosthetic teeth, transfers forces from chewing to supporting teeth or gums, and replaces missing jawbone and gums. A metal denture base uses a metal material in contact with the gums which teeth are attached to, either with plastic overlay or cement. It is indicated when further bone loss is not expected, a reinforced tooth is needed, or for a floating denture concept. Advantages are rigidity, thermal conductivity and stability, while disadvantages include difficulty adjusting the metal to gums and lack of esthetics.
1) The patient presented with pain in lower right and left teeth and was found to have multiple dental issues including bad oral hygiene, decayed tooth #27, and multiple carious teeth.
2) The proposed treatment plan involved multiple phases including nonsurgical treatments like cleanings, fillings, and root canals as well as a future referral for orthodontics to address spacing issues.
3) Clinical treatments included fillings for several teeth, two root canal treatments to address teeth #34 and #46 which presented with pain and swelling, and oral hygiene instruction. Post-treatment photographs showed improvements in the patient's dental condition.
Dr. Muhammad Sohail presented information on tooth agenesis/hypodontia, which is characterized by the absence of one or more teeth. Some key points include:
- The prevalence is 2.7-12.2% in permanent dentition excluding third molars.
- Genetic and environmental factors can contribute to its etiology.
- Treatment depends on the number and location of missing teeth and may include space closure, autotransplantation, or prosthetic replacement.
- Management requires a multidisciplinary approach including orthodontics, prosthodontics, oral surgery and restorative dentistry.

A treatment plan is developed based on the diagnosis. Success requires consideration of the patient's attitude and ability to use dentures, as well as the clinician's skills.
Unlocking the mysteries of reproduction: Exploring fecundity and gonadosomati...AbdullaAlAsif1
The pygmy halfbeak Dermogenys colletei, is known for its viviparous nature, this presents an intriguing case of relatively low fecundity, raising questions about potential compensatory reproductive strategies employed by this species. Our study delves into the examination of fecundity and the Gonadosomatic Index (GSI) in the Pygmy Halfbeak, D. colletei (Meisner, 2001), an intriguing viviparous fish indigenous to Sarawak, Borneo. We hypothesize that the Pygmy halfbeak, D. colletei, may exhibit unique reproductive adaptations to offset its low fecundity, thus enhancing its survival and fitness. To address this, we conducted a comprehensive study utilizing 28 mature female specimens of D. colletei, carefully measuring fecundity and GSI to shed light on the reproductive adaptations of this species. Our findings reveal that D. colletei indeed exhibits low fecundity, with a mean of 16.76 ± 2.01, and a mean GSI of 12.83 ± 1.27, providing crucial insights into the reproductive mechanisms at play in this species. These results underscore the existence of unique reproductive strategies in D. colletei, enabling its adaptation and persistence in Borneo's diverse aquatic ecosystems, and call for further ecological research to elucidate these mechanisms. This study lends to a better understanding of viviparous fish in Borneo and contributes to the broader field of aquatic ecology, enhancing our knowledge of species adaptations to unique ecological challenges.
Phenomics assisted breeding in crop improvementIshaGoswami9
As the population is increasing and will reach about 9 billion upto 2050. Also due to climate change, it is difficult to meet the food requirement of such a large population. Facing the challenges presented by resource shortages, climate
change, and increasing global population, crop yield and quality need to be improved in a sustainable way over the coming decades. Genetic improvement by breeding is the best way to increase crop productivity. With the rapid progression of functional
genomics, an increasing number of crop genomes have been sequenced and dozens of genes influencing key agronomic traits have been identified. However, current genome sequence information has not been adequately exploited for understanding
the complex characteristics of multiple gene, owing to a lack of crop phenotypic data. Efficient, automatic, and accurate technologies and platforms that can capture phenotypic data that can
be linked to genomics information for crop improvement at all growth stages have become as important as genotyping. Thus,
high-throughput phenotyping has become the major bottleneck restricting crop breeding. Plant phenomics has been defined as the high-throughput, accurate acquisition and analysis of multi-dimensional phenotypes
during crop growing stages at the organism level, including the cell, tissue, organ, individual plant, plot, and field levels. With the rapid development of novel sensors, imaging technology,
and analysis methods, numerous infrastructure platforms have been developed for phenotyping.

Deep Behavioral Phenotyping in Systems Neuroscience for Functional Atlasing a...Ana Luísa Pinho
Functional Magnetic Resonance Imaging (fMRI) provides means to characterize brain activations in response to behavior. However, cognitive neuroscience has been limited to group-level effects referring to the performance of specific tasks. To obtain the functional profile of elementary cognitive mechanisms, the combination of brain responses to many tasks is required. Yet, to date, both structural atlases and parcellation-based activations do not fully account for cognitive function and still present several limitations. Further, they do not adapt overall to individual characteristics. In this talk, I will give an account of deep-behavioral phenotyping strategies, namely data-driven methods in large task-fMRI datasets, to optimize functional brain-data collection and improve inference of effects-of-interest related to mental processes. Key to this approach is the employment of fast multi-functional paradigms rich on features that can be well parametrized and, consequently, facilitate the creation of psycho-physiological constructs to be modelled with imaging data. Particular emphasis will be given to music stimuli when studying high-order cognitive mechanisms, due to their ecological nature and quality to enable complex behavior compounded by discrete entities. I will also discuss how deep-behavioral phenotyping and individualized models applied to neuroimaging data can better account for the subject-specific organization of domain-general cognitive systems in the human brain. Finally, the accumulation of functional brain signatures brings the possibility to clarify relationships among tasks and create a univocal link between brain systems and mental functions through: (1) the development of ontologies proposing an organization of cognitive processes; and (2) brain-network taxonomies describing functional specialization. To this end, tools to improve commensurability in cognitive science are necessary, such as public repositories, ontology-based platforms and automated meta-analysis tools. I will thus discuss some brain-atlasing resources currently under development, and their applicability in cognitive as well as clinical neuroscience.

The use of Nauplii and metanauplii artemia in aquaculture (brine shrimp).pptxMAGOTI ERNEST
Although Artemia has been known to man for centuries, its use as a food for the culture of larval organisms apparently began only in the 1930s, when several investigators found that it made an excellent food for newly hatched fish larvae (Litvinenko et al., 2023). As aquaculture developed in the 1960s and ‘70s, the use of Artemia also became more widespread, due both to its convenience and to its nutritional value for larval organisms (Arenas-Pardo et al., 2024). The fact that Artemia dormant cysts can be stored for long periods in cans, and then used as an off-the-shelf food requiring only 24 h of incubation makes them the most convenient, least labor-intensive, live food available for aquaculture (Sorgeloos & Roubach, 2021). The nutritional value of Artemia, especially for marine organisms, is not constant, but varies both geographically and temporally. During the last decade, however, both the causes of Artemia nutritional variability and methods to improve poorquality Artemia have been identified (Loufi et al., 2024).
Brine shrimp (Artemia spp.) are used in marine aquaculture worldwide. Annually, more than 2,000 metric tons of dry cysts are used for cultivation of fish, crustacean, and shellfish larva. Brine shrimp are important to aquaculture because newly hatched brine shrimp nauplii (larvae) provide a food source for many fish fry (Mozanzadeh et al., 2021). Culture and harvesting of brine shrimp eggs represents another aspect of the aquaculture industry. Nauplii and metanauplii of Artemia, commonly known as brine shrimp, play a crucial role in aquaculture due to their nutritional value and suitability as live feed for many aquatic species, particularly in larval stages (Sorgeloos & Roubach, 2021).
EWOCS-I: The catalog of X-ray sources in Westerlund 1 from the Extended Weste...Sérgio Sacani
Context. With a mass exceeding several 104 M⊙ and a rich and dense population of massive stars, supermassive young star clusters
represent the most massive star-forming environment that is dominated by the feedback from massive stars and gravitational interactions
among stars.
Aims. In this paper we present the Extended Westerlund 1 and 2 Open Clusters Survey (EWOCS) project, which aims to investigate
the influence of the starburst environment on the formation of stars and planets, and on the evolution of both low and high mass stars.
The primary targets of this project are Westerlund 1 and 2, the closest supermassive star clusters to the Sun.
Methods. The project is based primarily on recent observations conducted with the Chandra and JWST observatories. Specifically,
the Chandra survey of Westerlund 1 consists of 36 new ACIS-I observations, nearly co-pointed, for a total exposure time of 1 Msec.
Additionally, we included 8 archival Chandra/ACIS-S observations. This paper presents the resulting catalog of X-ray sources within
and around Westerlund 1. Sources were detected by combining various existing methods, and photon extraction and source validation
were carried out using the ACIS-Extract software.
Results. The EWOCS X-ray catalog comprises 5963 validated sources out of the 9420 initially provided to ACIS-Extract, reaching a
photon flux threshold of approximately 2 × 10−8 photons cm−2
s
−1
. The X-ray sources exhibit a highly concentrated spatial distribution,
with 1075 sources located within the central 1 arcmin. We have successfully detected X-ray emissions from 126 out of the 166 known
massive stars of the cluster, and we have collected over 71 000 photons from the magnetar CXO J164710.20-455217.

The debris of the ‘last major merger’ is dynamically youngSérgio Sacani
The Milky Way’s (MW) inner stellar halo contains an [Fe/H]-rich component with highly eccentric orbits, often referred to as the
‘last major merger.’ Hypotheses for the origin of this component include Gaia-Sausage/Enceladus (GSE), where the progenitor
collided with the MW proto-disc 8–11 Gyr ago, and the Virgo Radial Merger (VRM), where the progenitor collided with the
MW disc within the last 3 Gyr. These two scenarios make different predictions about observable structure in local phase space,
because the morphology of debris depends on how long it has had to phase mix. The recently identified phase-space folds in Gaia
DR3 have positive caustic velocities, making them fundamentally different than the phase-mixed chevrons found in simulations
at late times. Roughly 20 per cent of the stars in the prograde local stellar halo are associated with the observed caustics. Based
on a simple phase-mixing model, the observed number of caustics are consistent with a merger that occurred 1–2 Gyr ago.
We also compare the observed phase-space distribution to FIRE-2 Latte simulations of GSE-like mergers, using a quantitative
measurement of phase mixing (2D causticality). The observed local phase-space distribution best matches the simulated data
1–2 Gyr after collision, and certainly not later than 3 Gyr. This is further evidence that the progenitor of the ‘last major merger’
did not collide with the MW proto-disc at early times, as is thought for the GSE, but instead collided with the MW disc within
the last few Gyr, consistent with the body of work surrounding the VRM.
