Published: October 2023

The activity of light-harvesting polymeric materials, an encouraging
photocatalyst for industrial submission, is extremely restricted by low
crystallinity. However, the main bottlenecks are photocatalysts’ low
activity and poor selectivity. Herein, a soft-template induction
strategy is proposed to synthesize a metal-free heterojunction of
perylene tetra-anhydride
(PT)-based-5,15-di-(4-aminophenyl)-10,20-diphenyl porphyrin (BP), i.e.,
PTBP polymer with excellent crystallinity and solar light harvesting
ability. Therefore, solar-powered molecular artificial pho-tosynthesis
using PTBP polymeric frame-work system as a photocatalyst functions in a
highly efficient manner, leading to high 1,4-NADH/NADPH regeneration
(52.41/58.41%), followed by NADH consumption in exclusive formic acid
production (119.25 μmol) from CO2 in 1 hrs, and sparking dopamine
oxidation into Leucodopamine-chrome with excellent yields (50.37%) than
PT (13.93%). The PTBP polymeric framework’s remarkable photo-catalytic
performance is ascribed to its unique bio-boosted photocatalytic cascade
system, thermal solid stability, reusability, and wide solar light
response range. This research opens the door to enhancing the
photocatalytic ability of the PTBP polymeric framework.

Seed predation by rodents can act as a biotic barrier, limiting the
establishment of exotic species. Predation rates of exotic seeds may
depend on their attractiveness, determined by their traits and how
different they are from natives. Additionally, at the naturalization
stage of the invasion process, exotic seeds may escape post-dispersal
predation because they are uncommon in the community. To test these
ideas, we assessed granivory in a Patagonian forest, where two species
with contrasting seed sizes are naturalized. Rubus idaeus seeds are of
similar size to native species, whereas Prunus cerasus seeds are four
times larger. The relative abundance of their seeds within the landscape
is low (< 3%) compared to native seeds (97%). Throughout the
fruiting season, we offered seeds from all species present in the
community (native and exotics), whenever they were available in the
landscape. To consider the effects of vegetation structure on rodent
foraging behavior, we offered seeds in areas with or without understory
cover. Seed size affected the probability of removal, with rodents
preferentially foraging on those of intermediate sizes. Consequently,
they strongly avoided large Prunus seeds, but removed Rubus seeds at
similar rates to natives. Contrary to our expectations, seed abundance
did not affect predation, and hence, rarity did not confer an advantage
to exotic seeds. Finally, the presence of shrub cover increased 2.3
times the removal rates compared to open areas. Concluding, the
dissimilarity in seed size compared to native species and the presence
of shrub cover influenced the predation pressure on exotic species
within our community.

Published: October 2023

This paper describes the clinicopathological features, treatment and
22-month follow-up of a melanoma involving the coronary band and hoof
wall lamellae in a 12-year-old bay Andalusian gelding. The horse
exhibited a mild right forelimb lameness and history of recurrent
lameness and abscessation for an ongoing 10-month period. Based on
clinical and radiological examination, a keratoma at the dorsolateral
aspect of the hoof, as well as a plaque-like pigmented lesion at the
coronary band were diagnosed. Both lesions were removed.
Microscopically, a melanoma with dermo-epidermal activity (resembling
superficial spreading melanoma), was diagnosed. Further diagnostic
imaging techniques showed no involvement of the surrounding structures
beyond the superficial dermis. Therefore, a surgical removal of the
mass, with a partial hoof wall resection was performed, and local
cisplatin chemotherapy was administered. After partial regression at 6
months, the control biopsies at 12, 18 and 22 months confirmed the
persistence of tumour nests with dermo – epidermal growth pattern
without further invasion of deep structures or metastasis.
Predicting alpha amylase content and starch breakdown in pregerminated barley seeds using hyperspectral imaging
Authors: Propst Kevin , Hall Evan , Hirsch Cory D , Walling Jason G
Published: October 2023

Malting is the process of controlled germination of cereal grain that is
steeped, germinated, and dry kilned to develop flavor compounds,
fermentable sugars, the hydrolytic enzymes necessary for the brewing
process. To meet the strict standards of the brewing industry, variation
in the germination of barley grains need to be minimal but also maintain
rapid germination and optimum levels of a and B amylase. Preharvest
sprouting poses a significant threat to barley cultivars prior to
harvest, resulting in premature endosperm modification, reduced enzyme
content, and poor malthouse performance. Pregerminated grain is
difficult to detect as there are often no signs of damage, and current
methods such as the Hagberg falling/Stirring number, or pearling tests,
each of which ultimately leads to the destruction of the seed. Here we
used time-series hyperspectral imaging of barley seeds undergoing active
and or pregerminated seed and used a deep neural network to predict
stirring number and alpha amylase values, which are proxy measures for
sprout damage. Prediction models were made for seven genotypes tested
individually and with all genotypes combined. Stirring number assays
ranged from 0 to 190 and our prediction models had mean average errors
of 10.5 to 23.9 depending on the model. To increase the resolution and
accuracy of the predictions we transitioned from using bulk conventional
molecular assays to single seed assays and prediction models. These
results demonstrate that hyperspectral imaging and machine learning
models can be used to predict germinated grain in bulk and single seed
assays.
Utilizing Neural Radiance Fields (NeRFs) Understand Nutrient Stress Phenotypes in 3D
Authors: Swartz Landon , Palaniappan Kannappan , Mendoza-Cozatl David
Published: October 2023

In precision agriculture and plant biology, monitoring nutrient stress
in crops is of paramount importance for ensuring optimal yield and
resource utilization. However, nutrient stress phenotypes can be
nuanced, subtle, and display in a variety of ways. We propose using
Neural Radiance Fields (NeRFs) for the organized reconstruction of plant
structures to observe the changes of plant structure and color under
nutrient stress.Neural Radiance Fields, a cutting-edge technique in
computer vision, leverage neural networks to model complex
high-frequency geometry directly from 2D images, offering high-fidelity
reconstructions. This methodology holds immense potential for plant
imaging, as it allows for the creation of detailed and organized 3D
models that can capture subtle alterations in plant morphology
associated with nutrient stress responses.The proposed methodology
involves the acquisition of high-resolution images of plants under
different nutrient conditions. These images are inputted to the
NeRFStudio Nerfacto implementation, a NeRF model that is a
aggregation of many different existing models. A 3D reconstruction of
the scene is outputted from the model and can be further reduced to a
point cloud containing point locations, colors, and normals. Phenotypic
traits are then calculated from the point clouds. The reconstructed
plant models enable the quantitative analysis of morphological changes
associated with nutrient stress. This includes alterations in leaf size,
branching patterns, and overall plant geometry. The utilization of NeRFs
allows for non-destructive monitoring, offering a significant advantage
over traditional methods that may be labor-intensive or invasive.This
research not only contributes to the field of precision agriculture but
also presents a powerful tool for plant biologists to deepen their
understanding of how nutrient stress impacts plant architecture. The
insights gained from this approach have the potential to inform
precision nutrient management strategies, leading to more sustainable
and efficient agricultural practices.

Fusarium head blight (FHB) is an economically important disease in wheat
which can cause yield losses >50%. Breeding for host
resistance is the most effective control method, however time, labor,
and human subjectivity limit phenotyping efforts. A novel,
high-throughput phenotyping rover was used to collect in-field RGB
images of inoculated wheat spikes at multiple time points in 2021 and
2022. A deep neural network pipeline was developed to classify wheat
spikes, segment healthy and diseased tissue, and quantify FHB severity
as the region of intersection between spike and disease masks. To
validate the pipeline, model inferences on a plot and spike scale were
compared to five raters who performed disease scoring in the field and
on images. The precision and throughput of the phenotyping rover and FHB
quantification pipeline exceeded conventional rating methods. The plot
aggregate disease scores based on pipeline outputs correlated strongly
with plot-level disease scores by raters in the field and imagery. When
comparing disease annotations on spike images, pipeline to human disease
correlations were equivalent to correlations between raters, however
location tended to influence disease assessment. The pipeline has strong
generalizability and performed well on images taken across environments,
with different camera orientations, and throughout disease progression.
These results demonstrate a breakthrough in FHB phenotyping and
facilitate precise and efficient disease quantification on spikes and
plot aggregates across time and imaging conditions that are unachievable
using conventional methods.
Genome-Wide Association study for root nodulation in field Soybean
Authors: Ghimire Niraj , Dumenyo Korsi , Taheri Ali
Published: October 2023

Nitrogen is a crucial nutrient for soybean growth and production.
Enhancing soybean crop yield is essential to address the growing
challenge of ensuring food security. While nodulation and nitrogen
fixation reduce the need for additional nitrogen, the presence of
actively fixing nodules, distinguished by their pink or red color,
ensures effective nitrogen fixation and yield improvement in soybeans.
Changes in global climate led to shifts in soil characteristics that
restrict root growth and create conditions resembling drought,
diminishing the capacity of plant roots to absorb water and nutrients,
consequently impacting overall plant growth as well as nodulation
related traits. In this research, we’re examining nodulation related
traits across 500 late maturing soybean accessions. We germinated seeds
on germination paper and transferred them to blue blotting papers and
captured root images after 21 days. Nodulation traits such as Nodules
number and area will be evaluated using the Soybean Nodule Acquisition
Pipeline (SNAP). Statistical assessments including population structure,
kinship matrix, and principal component analysis will be measured using
R. We’ll utilize both phenotypic data and SNPs from Illumina Infinium
SoySNP50K iselect SNP Beadchip for Genome-wide Association Studies
(GWAS) using the GAPIT package in R. This study aims to identify genetic
regions linked to nodulation traits, potentially uncovering valuable
QTLs or genes for enhancing nodulation related traits.
Utilizing a 3D Global P-Wave Tomography Model to Improve Backprojection Imaging: A Case Study of the 2015 Nepal Earthquake
Authors: Song Chao , Ge Zengxi
Published: October 2023

We carry out a backprojection analysis of high-frequency P-wave signals
to image the rupture process of the 8 September 2017 Mw 8.2 Chiapas
earthquake based on the 3D velocity model LLNL-G3Dv3. Results show that
the entire ∼56 s unilateral rupture process clearly involves two stages.
The first stage lasted for ∼37 s, with a northwest (∼322° azi- muth)
propagation over a length of ∼89 km at a speed of ∼2:8 km=s. Then, the
rupture made a right turn within a short distance and propagated to
∼348° azimuth for ∼74 km at a higher speed of ∼4:6 km=s. The two-stage
rupture was further confirmed by the power release, data coherency,
beamforming patterns, and aftershock distribution. The overall rupture
can be well explained by a two-fault model. Rupture on the second fault
was positively triggered by that on the first one. The Tehuantepec
Fracture Zone, which transversely intersects the Middle American trench
as well as the coseismic rupture zone, likely functioned as a barrier to
the first stage. Upon reaching the barrier, the rupture was temporarily
blocked and deceler- ated, but eventually detoured to cross the barrier
with the aid of the accumulated stress. The abrupt release of stress led
to a much higher rupture speed in the second stage.

The Importance of Changing the Model of Care in Residential Care Homes: A Person-Centered Approach
Authors: PG Lozano
Published: October 2023

After pandemic, many professionals have realized that the current model of care in residences is far from the care that is intended to be provided to the elderly. The person-centered care model takes into account the person's preferences and interests, as well as promoting their autonomy in daily decisions. It is currently booming after numerous studies have shown exceptional results about the quality of care received by residents. Occupational Therapy is closely linked to this model from its bases, always keeping in mind the person and their occupation before starting the development of treatments. A change is necessary in all centers that care for the elderly, providing the highest quality of life and well-being.
Dry Needling and Pain Drawings: An Exploratory Study
Authors: Louw Adriaan
Published: October 2023

Background: Emerging evidence shows that altered cortical brain maps play a key role in the initiation and maintenance of a human pain experience and therapeutic treatments may positively influence these maps and reduce pain and disability. Objective: To determine if dry needling for spinal pain can positively alter body pain diagrams and if those changes correlate to a reduction in self-reported pain ratings. Design: Case series with pre- and immediate post-intervention measurements. Methods: A convenience sample of adult patients attending physical therapy with back or neck pain meeting inclusion criteria for dry needling was recruited for the study. Prior to dry needling, patients completed a demographics questionnaire, filled in a body pain diagram (color where you hurt) and a self-reported pain rating (numeric pain rating scale). Patients then received a standard dry needling session for the affected area and immediately following dry needling completed a body pain diagram, self-reported pain rating and satisfaction with the treatment using the global rating of change scale. Results: Forty-three patients (76.74% female) participated in the study with 19 patients presenting with low back pain and 24 with neck pain. Following dry needling, mean pain rating for the whole cohort was reduced (p<0.001), with larger effect for low back pain (p < 0.001) than neck pain (p = 0.031). Overall, the whole patient sample’s body pain diagram decreased in size by 50.16% following DN (95%CI = 10.8, 22.6; t(42)=5.67, p < 0.001). When broken down between neck and low back pain, low back maps shrunk by 61.84% (95%CI= 16.1 - 38.6), t(18)=5.1, p < 0.001), whereas neck maps decreased by 33% (95%CI= 4.3 - 12.2, t(23)=4.4, p < .001). Positive correlations were found between the size of the body pain drawings and pain intensity (rs = 0.461 (p = 0.002) as well as reduction of pain after dry needling and reduction in body map drawings (rs = 0.305 (p = 0.047). Conclusion: Dry needling can reduce body map drawings, which correlates to the intensity of pain. A potential underlying mechanism of dry needling may be its effect on neuroplasticity. Additional research is needed to further explore these emerging results.

Published: October 2023

A Matemática se constitui enquanto ciência dinâmica, presente desde o início da história humana, utilizada para resolver problemas e desenvolver estratégias de planejamento. Nasce, portanto, das necessidades do homem, uma criação contínua, sempre em movimento. Esta reflexão, porém, não é comum e o que se percebe é uma problemática associada às formas como os sujeitos – alunos e comunidade geral – concebem a matemática, associada a uma ciência pouco acessível e, quando acessível, como privilégio de “mentes brilhantes”. Neste sentido, o presente texto objetiva apresentar uma experiência de criação de espaços de interação entre sujeitos e diferentes objetos e representações matemáticas, no intuito de desmistificar o acesso a esta ciência e proporcionar momentos de aproximação e promoção do interesse e da curiosidade pela matemática. O marco inicial deu-se por meio de um projeto de ensino, pesquisa e extensão desenvolvido em 2022 por estudantes e professores do curso de Licenciatura em Matemática do Instituto Federal Catarinense – IFC Campus Concórdia. O projeto abarcou o estudo e seleção de diferentes objetos e representações que foram organizados estrategicamente em espaços de grande circulação na instituição e fora dela, oferecendo a possibilidade de o público interagir com os objetos/representações. “Totens” foram organizados, contendo materiais informativos e objetos de interação de acesso livre. Além da interação física, foi criado um espaço virtual em rede social para atingir um maior número de sujeitos e democratizando o acesso aos conhecimentos abarcados. Em um primeiro momento os totens foram alocados nos espaços do Campus Concórdia e, após, em uma escola e no espaço público de uma feira municipal do livro. Observações dos estudantes bolsistas, materializadas de forma escrita, foram consideradas na coleta de informações sobre os efeitos do projeto sobre os sujeitos. Na dimensão do ensino, resulta a interação em número significativo de sujeitos com os objetos, suscitando a capacidade de organização mental e lógica-matemática. No âmbito da extensão, a articulação entre o IFC, seus estudantes e professores e a comunidade externa. Na pesquisa, as observações sobre os efeitos que os objetos trouxeram/proporcionaram, do ponto de vista de alunos, estudantes e demais sujeitos que os acessaram. A reflexão final sugere que os sujeitos têm dificuldades em relacionar os conhecimentos matemáticos aos objetos de representação, associando a matemática a ideias abstratas e pouco interessantes, a números e representações algorítmicas incipientes de sentido. Logo, ações que mostrem faces práticas, lúdicas e interessantes da matemática se tornam importantes catalizadores para desmistificar crenças sobre a inacessibilidade dessa ciência aos diferentes sujeitos da sociedade.

It investigates how these collaborations are adjusted to existing structures to facilitate the movement of knowledge. The study draws attention to the gaps or seams (Vertesi, 2014) that arise when occupational health services providers and employers have different interests and objectives concerning occupational health and safety and explores the continuous and often unnoticed relational work (Zelizer, 2012) undertaken by occupational health services providers to make their expertise and services relevant and appealing to customers and employers. This article contributes to the ongoing discussion on alignment work (Kruse, 2021, 2023) by highlighting its current limitations and underscoring the importance of relational work in creating the necessary conditions for moving knowledge.
Numerical Simulation of Designing a Braking System by Comparing Pressure in Minibus Type Vehicle
Authors: Hibatullah Naufal Aflah , Subardjah Adri Maldi
Published: October 2023

The braking system is crucial in maintaining the vehicle's safety to avoid fatality. However, designing a vehicle braking system can take significant time and energy. Hence, a method to design a braking system that requires less time and energy is necessary. The vehicle specifications will affect the braking design process in designing a braking system. In addition, the existing government regulations limit the braking capacity that must be achieved during the braking process. These two things become the limitations in designing an optimal braking system. The design process is carried out by determining the required pressure for the braking process and the pressure generated during the braking process. The generated pressure must exceed the required pressure for the braking system design to work appropriately. The conditions mentioned earlier can be achieved by iterating and selecting the standard component. A case study in the form of braking system design has been carried out where the braking system can generate a pressure of 4.14 MPa and requires a pressure of 3.13 MPa and 2.34 MPa at the front and rear caliper on a vehicle weighing 78.48 kN to decelerate 5 ms-2 as required in Indonesia government regulation. A comparison is made with other methods proposed by other researchers to ensure the proposed method can be applied to various conditions. The comparison results show that the proposed method can be applied to various conditions. Moreover, the proposed method can minimize the difference in pressure between the generated and the required pressure to avoid overdesign.

In the present study, a tensile test was performed to measure the tensile strength of PETG (Polyethylene terephthalate glycol) specimen with the combination of different layer height, infill geometry, nozzle temperature, and fan speed whereas other parameters are kept at a constant level. This study uses the ISO 527 1BA standard. Taguchi L16 (44) with 4 levels for each factor was used to determine the effect of each parameter. Each experiment repeated 3 times to minimize the occurrence of errors. layer height, infill geometry, nozzle temperature, and fan speed ​​respectively effect of 13.4%, 63.6%, 19.0%, and 2.7%. Fan speed is considered a parameter that has no impact on tensile strength. The layer height and nozzle temperature parameter shows that the higher the value, the tensile strength of specimens tend to increase. Furthermore, infill geometry from the one with the highest to the lowest tensile strength value is gyroid, zig-zag, grid, and triangles. The combination of layer height of 0.24 mm, infill geometry gyroid, and nozzle temperature of 250 ˚C is the optimum combination of parameters which has the highest tensile strength of 34.76 N/mm2.

Metal forming uses plastic deformation to change the shape of the workpiece. Deformation or change in shape results from the use of a tool which is usually called a die. The die provides stresses that exceed the yield strength of the material (plastic). The forging process is one of several types of metal forming. A power hammer machine is a machine used for the formation of a product in the manufacturing process, namely with a system of continuous forging/pressure on the specimen so that the deformed specimen becomes denser and stronger according to the desired shape. The forging process is superior to other processes such as casting and machining. The effectiveness of the forging process is characterized by low costs, high productivity, and high product quality. The cold forging process needs to be improved to reduce the occurrence of fine cracks and defects. The main factor is the quality of forging results by planning the design and production of the right die, improving product quality, and reducing the number of defective products to encourage industrial competitiveness. The method in this research is the process of making the design and calculation of the main components and making the power hammer machine. The results of the design and manufacture of the power hammer machine obtained that the impact force from the design was 58.3 Kg, the rotation of the drive shaft to drive the hammer was 206.5 Rpm, the diameter of the driving shaft was 12.36 mm with the one made of 16 mm, the torque on the driving motor was 77.9 Nm, the minimum power designed is 2.2 hp with a rotation of 2800 Rpm, and is selected for the manufacture of 3 Hp, the electrical system is on / off using a throttle stomp.

Alumni data collection activities as material for recapitulating the data needed as the completeness of accreditation documents and performance evaluation documents for tertiary institutions. This will not be achieved if the data collection is still using manual methods such as contacting the graduates one by one. This activity will take up time and the data that has been collected so far is not optimal. The purpose of conducting this research is to develop information technology in tracing graduates using the Google form at the product validity testing stage. This research is development research using 4D models. The validation test was carried out at the development stage, for this reason, the research was limited to the product development phase only. The instrument used for the validation test is in the form of a validity questionnaire for the product being developed. Questionnaires will be distributed and then the product will be validated based on the statements that have been prepared beforehand. The validators who validate the product are 4 expert lecturers. The assessment is carried out based on material aspects and media aspects. The results of product research developed with an information technology approach are in the valid category. Not until this stage, the product that has been declared valid, then revised again based on suggestions by experts. It is hoped that after obtaining validation data for the product, the next step is to carry out practicality tests and effectiveness tests so that the product can be disseminated and can be used in education, especially in the graduate study tracer at the Department of Automotive Engineering FT-UNP

Listening proficiency is essential in language acquisition, yet both its classroom time and research are overshadowed by other skills, such as speaking and reading. To tackle the issue of limited classroom time, extensive listening is one of the most convenient and effective solutions. Selecting the materials, however, needs an equally extensive effort; especially for the authentic ones.  Therefore, this study aims to investigate the speech rate and vocabulary level of TED-Ed videos as one of the sources of authentic material for extensive listening to determine their suitability for EFL learners. The research used a quantitative descriptive design with purposive sampling. The data collection of Speech Rate is conducted by transcribing the sample videos and dividing the number of words by the length of the video, and the result is measured in terms of WPM (Word Per Minute). To get the vocabulary level, the video transcripts are put into the Vocabkitchen website to analyze the vocabulary CEFR level for each word. From the analysis, the average speech rate of TED-Ed videos is 147.4 WPM and it is suitable for all levels of EFL learners, including beginner level. Meanwhile, the CEFR level of the vocabulary is more suitable for intermediate EFL learners and beyond.

This study sought to establish whether students who are exposed to Controlled Extensive Reading Tasks (CERTs) will have higher learning outcomes during English as a Second Language (ESL) lessons. A 3-month intervention pilot of Controlled Extensive Reading (CER) instruction, was implemented in two secondary schools in Kakamega County, Western Kenya, from February to May 2023. We compared the impacts of the CERTs treatment group in ESL lessons in the pilot school with those of the control group that did not use the intervention but utilized the same instructional components. The findings revealed that assignment to the CERTs pilot group had additional improvement in the target language skills while the control group had somewhat constant learning outcomes. The study is useful to curriculum stakeholders who should consider such results alongside existing implementation strategies in ESL policies and program designs.
PERENCANAAN KONDENSOR TIPE KOIL VERTIKAL UNTUK KONDENSASI UAP PIROLISA BIOMASSA TEMPURUNG KELAPA

Proses pirolisis sejatinya adalah proses pembakaran tidak langsung atau proses pemanasan terhadap biomassa pada suhu tinggi (250 – 650) oC. Proses pirolisa menghasilkan uap panas atau sering disebut dengan uap pirolisis ataupun volatiles. Uap pirolisis akan berubah wujud menjadi cairan (condensate) bila didinginkan. Selain menghasilkan cairan juga menghasilkan gas yang dapat terbakar (producer gas). Tujuan kajian ini adalah mendesain dan menguji secara teoritis alat kondensasi asap pirolisis dari biomassa. Untuk proses kondensasi dibutuhkan alat perpindahan panas (heat exchanger) dimana panas laten yang dimiliki uap pirolisis harus segera dibuang (reject) menggunakan cairan pendingin (coolant) agar suhunya menurun hingga mendekati suhu saturasinya sehingga proses kondensasi dapat berlangsung. Kondensor tabung-koil spiral vertical (shell-coiled tubes) dapat menjadi solusi untuk masalah kondensasi uap panas pirolisis biomassa bila direncanakan dengan tepat. Kondensor jenis ini sangat simple dan mudah dalam hal maintenance. Merencanakan kondensor tipe tabung-koil berdasarkan analisis hidrodinamik membawa para perancang (engineer) semakin dekat dengan alat pendingin uap pirolisis dengan kinerja yang tinggi. Dari hasil analisis bahwa penambahan jumlah gulungan koil dapat meningkatkan efektifitas pendinginan.

The Electronic-Based Governance System (EBGS) mandates institutions at every level to manage their governance electronically. As a medium for managing authentic evidence stemming from an activity, archiving systems need to establish themselves as part of this electronic-based governance system. Hence, the process of archive distribution, as a component of the archiving system, becomes an issue that requires in-depth study through research. This raises the research question, "How can we comprehensively describe the archive distribution process at the West Java Provincial Department of Tourism and Culture through the Sidebar application?". The research aims to obtain a comprehensive description of the archive distribution process within the West Java Provincial Department of Tourism and Culture via the Sidebar application. The research method used is qualitative with a descriptive approach and uses the archival staff of the West Java Cultural and Tourism Department as informants. Data is collected through observation, interviews, and literature studies, with data analysis through reduction, presentation, and conclusion drawing. The results show that in distributing archives, the West Java Cultural and Tourism Department utilizes various features in the Sidebar application, such as Incoming Mail, Copy Mail, Manuscript Digital Signature, Outbox, and Manuscript Validation. The West Java Department of Tourism and Culture uses these features in internal and external archival operational activities. It can be concluded that the features in the Sidebar application can be used for real-time archive distribution with various statuses like "Revise Manuscript," "Review Manuscript," and "This Manuscript has been acted upon," which have been implemented in the West Java Department of Tourism and Culture.

OBJECTIVE

To determine the effects of using either a linear or curvilinear oscillating, battery-powered saw blade on the extent of bone resection, bone fissure or fragmentation, soft tissue trauma, and surgical time for femoral head and neck excision (FHNE) in feline cadavers.

ANIMALS

18 feline cadavers.

METHODS

Paired feline cadaveric femora were randomly assigned to either a 10 mm linear or 12 mm curvilinear blade for FHNE by 2 surgical residents. CT of each femur pre- and postoperatively were used to create 3D reconstructions of each femur. The residual remaining or excessively resected bone volume at the ostectomy site was compared to an “ideal” ostectomy line made by a board-certified surgeon on preoperative CTs.

RESULTS

There were no significant differences in residual or excessive bone resection by a saw blade (P = .84), between surgeons (P = .65), or in surgery time (P = .39). When compared to the “ideal” ostectomy, the linear saw blade removed slightly less bone compared to the curvilinear blade, but was not statistically significant (P = .82). No fissures or fractures were noted; however, the curvilinear blade removed the entire lesser trochanter in 1 cadaver and the linear blade partially removed the greater trochanter in 1 femur and 2 lesser trochanters in 2 femora.

CLINICAL RELEVANCE

The use of a curvilinear blade may be a viable option for performing FHNE in cats. In vivo studies are warranted to determine its efficacy in clinical cases where FHNE is performed and the incidence of complications postoperatively.
