Authors: Adinda Aprilia Kartika  , H.R. Adianto Mardijono
Published: September 2024

This study aims to determine the application of criminal law to acts of violence committed by the TNI which affect psychology and constraints on law enforcement in protecting victims of violence. This study uses a normative method with a statutory and conceptual approach. The result of this study is that legal protection for victims of domestic violence according to Law Number 23 of 2004 concerning the Elimination of Domestic Violence is urgently needed because all forms of violence, especially domestic violence, are violations of human rights and crimes against human dignity as well as other forms of discrimination. Victims of physical-psychological, sexual violence and neglect experience suffering and loss, so it is necessary to protect the rights of victims to obtain justice. Justice handed down to TNI members who commit crimes of domestic violence (KDRT) can be subject to disciplinary sanctions by their superiors, in this case military discipline laws can be imposed by superiors who have the right to punish (Ankum) then if the criminal element is proven then it will be resolved through a military court.

Published: September 2024

This research analyzes the role of the Kupang Class II Correctional Center (BAPAS) in guiding and developing children in conflict with the law. Using an empirical legal method, the study relies on primary and secondary data. The issue of juvenile delinquency in Indonesia is escalating, with 1,885 cases reported in 2018 and 1,098 in 2020. Notably, children are involved in physical violence (58 cases), sexual violence (44 cases), and theft (22 cases). This highlights the urgent need for institutions like BAPAS to support, develop, and supervise these children. The research addresses two main questions: (1) What is the role of BAPAS in guiding and mentoring children in conflict with the law? and (2) What challenges does BAPAS face in the juvenile justice system? The findings reveal that BAPAS's role is divided into three stages: (a) pre-adjudication guidance and development, (b) support during the trial process (adjudication), and (c) assistance post-trial. BAPAS encounters challenges primarily related to the families of the children, as well as difficulties faced by community guidance officers in providing effective assistance. It is crucial for BAPAS to develop persuasive communication skills to engage families and encourage active participation in the rehabilitation process. This includes involvement in training and understanding the community's role in supporting children in conflict with the law.

Supplying Accra with Market Garden Vegetables: An Eco-Sanitary and Socio-Economic Assessment of the Knowledge, Attitudes and Practices of Producers, Traders and Processors
Authors: ASSINOU Kokou Elom , KPOTCHOU Koffi
Published: September 2024

Like other cities in West Africa, Accra's market garden sector faces a number of sustainability challenges.  However, the sector's sustainability projects focus less on the knowledge, attitudes and practices (KAP) of the stakeholders in this food system, and more on the other factors that can enhance its socio-economic, health and ecological sustainability. Thus, the research aims to assess the level of health, socio-economic and environmental sustainability of market garden vegetable production, trade and processing in the Accra metropolitan district, based on the knowledge, attitudes and practices of stakeholders. A quantitative multi-criteria evaluation approach was adopted, using a questionnaire survey targeting 156 respondents (50 producers, 63 traders and 43 processors) selected by purposive sampling. The data collected by Kobocollect were processed using Excel, Arcgis and Google Earth. Average scores and good KAP rates were calculated for all players taken together, and particularly in consideration of the key dimensions of sustainable development. The results reveal low rates for ecological (28.24%), health (20.15%), socio-economic (36.15%), technological and innovative (14.25%) knowledge, attitudes and practices, evaluated overall at 26.87%. These results are unfavorable to the achievement of the SDGs, and do not meet either standard 13 of the Global Reporting Initiative (GRI) 2023, or the principles of nutritional ecology. Hence the importance of an integrated, long-term eco-nutritional education program for all stakeholders.

Model Predictive Control for Enhanced Trajectory Tracking of Autonomous Deep-Sea Tracked Mining Vehicles
Authors: Wu Hongyun , Chen Yuheng , Qin Hongmao
Published: September 2024

This paper explores the effectiveness of Model Predictive Control (MPC) for trajectory tracking in autonomous deep-sea tracked mining vehicles operating within polymetallic nodule mining environments, considering model uncertainties and external disturbances. Traditional applications of MPC in autonomous vehicle trajectory tracking, which typically rely on kinematic models under minimal external disturbance, often fail when faced with model inaccuracies and external disruptions. To address these challenges, we propose an MPC-based trajectory tracking algorithm that includes a speed correction controller for the drive wheel. This controller, developed through experimental data fitting, aims to mitigate issues such as vehicle body subsidence and track slippage. Tracking accuracy, particularly in curve navigation, is further enhanced through the use of Kalman Filtering (KF) and Adaptive Kalman Filtering (AKF) to counteract external disturbances. Moreover, we introduce an obstacle avoidance strategy utilizing a tri-circular arc trajectory with uniform curvature for path re-planning. This strategy effectively addresses dead zones and physical obstructions encountered during operation. The superiority of our approach compared to conventional Nonlinear MPC (NMPC) is demonstrated through extensive Simulink and Recurdyn co-simulations.
Numerical analysis of static stresses in partial hip implant
Authors: Čolić Katarina , Sedmak Simon , Sedmak Aleksandar , Milovanović Aleksa , Milošević Miloš
Published: September 2024

Research presented here involves numerical analysis of stresses in partial hip implant subjected to static loads, for two cases of patient weight. The numerical analysis requires the development of 3D models that would accurately represent real partial hip implant geometry, hence a reverse engineering approach via 3D scanning is also included. This combined approach provides reliable insight into the behaviour of partial hip implants under static load, while also exposing certain issues related to the application of this specific implant geometry at higher weight levels.

Published: September 2024

The onset of thermal convection in an electrically conducting rheological nanofluid to include an external vertical AC electric field saturated by a homogeneous porous medium has been studied using linear stability theory by employing an Oldroydian model which incorporates the effects of the electric field, Brownian motion, thermophoresis, and rheological parameters for bottom heavy distribution of nanoparticles. The rheology of the nanofluid is described by the Oldroydian model for calculating the shear stresses from velocity gradients. Exact solutions of the eigenvalue problem for stress-free bounding surface are obtained analytically using Galerkin method and the Darcy Rayleigh number for onset of both stationary and oscillatory convection, obtained for bottom-heavy distribution of nanoparticles. It is found that the Deborah number has a stabilizing effect on the system, while strain retardation time parameter has a destabilizing effect on the oscillatory convection of the system. The effect of the Lewis number tends to stabilize the stationary convection and destabilizes oscillatory convection. The concentration Rayleigh number has a destabilizing effect on stationary convection and a stabilizing effect on the oscillatory convection. Medium porosity has a stabilizing effect on oscillatory convection and is destabilizing on stationary convection. The effect of Vadasz number on oscillatory convection is destabilizing. AC electric field has a destabilizing effect on both the stationary and oscillatory convection.

Authors: Wani Khair ul Faisal , Nallasivam K.
Published: September 2024

The main aim of this study is to find out the static and modal response of the rigid pavement resting on different soil models subjected to aircraft loading. The FEM employed in this work is validated by a closed-form numerical problem, which is in great accord with previous research findings with a maximum divergence of 1.76 %. Furthermore, it has been investigated how the static response and cyclic frequency change as a result of variations in the thickness and span length of pavement, the modulus of the subgrade, different boundary conditions, and element discretization. Limited previous research has been performed in both static- and free vibration analysis of rigid pavement with 6 degrees of freedom (DOF). Also, very few researchers have carried out such a variety of parametric studies.
Digital image correlation application to structural integrity assessment
Authors: Aranđelović Mihajlo , Petrović Ana , Sedmak Simon
Published: September 2024

Digital image correlation represents a useful, efficient, and widely applied method of non-contact strain and displacement measuring in various types of structures. It is often combined with other means of integrity assessment, such as the finite element method and the use of fracture mechanics parameters. This paper presents a short overview of digital image correlation in various fields including mechanical and civil engineering, biomedicine, and some other, more ‘exotic’ examples. Additionally, some of the examples shown here perfectly illustrate the applicability of this method to cases where high levels of detail and accuracy are necessary in order to measure strain.

Published: September 2024

Background: The ability to diagnose myocardial infarction at a relatively early stage is considered to be highly important with the aim of increasing patient survival rate, especially in conditions of increased risk. The existing risk assessment models are somewhat misleading in terms of predictive validity.
Objective: This study evaluates the ability of the various machine learning models in the prediction of MI with especial emphasis on the neural networks’ performance as well as the comparison with the other traditional and other types of sophisticated models.
Methods: A cross-sectional study was conducted to collect the data from Electronic Health Records (EHRs) of the high-risk patients. The machine learning algorithms chosen were logistic regression, random forest, gradient boosting machines, and neural networks. The outcomes were measured in terms of accuracy, sensitivity, specificity and Area under the curve of the receiver operating characteristic (AUC-ROC).
Results: Thus, as it can be seen, the neural networks proved to be the most effective as they have the highest accuracy (91.3%) and AUC-ROC of (0.95). These models have shown better predictive accuracy compared with other techniques and most of the other forms of the machine learning models.
Conclusion: Neural networks improve the early identification of MI in high-risk groups adding potential betterment in clinical prognosis. These new models are still not implemented in everyday clinical practice, and their integration could revolutionise patient management, providing earlier and better-targeted treatments.
APPETITE STIMULANTS: INSIGHTS INTO PHARMACOLOGICAL INTERVENTIONS
Authors: Rizwana Mohammed , Fathima Syeda Nishat
Published: September 2024

ABSTRACT: Chronic and acute illnesses can impact patients’ appetite and weight, potentially leading to cachexia. Although these changes typically progress over weeks to months, acutely ill patients may experience a loss of appetite and subsequent weight loss in a shorter period, potentially causing further complications like severe anorexia, cachexia, depression, and increased infection risk. These complications may necessitate additional therapies and longer hospital stays. Therapy should focus on preventing further weight loss or facilitating weight gain, especially in aging patients and those with psychological disorders, malignancy, chronic infections, and other chronic disease states. Unintentional weight loss, defined as 5% of body weight in a month or 10% in a 6-month period, may occur more rapidly in acutely ill patients. Medications like dronabinol, megestrol, and mirtazapine can help patients improve appetite and gain weight over weeks to months. Keywords: Appetite; Orexigenic; Dronabinol; Megestrol; Mirtazapine

ABSTRACT The Biopharmaceutical Classification System (BSC) classifies Candesartan Cilexetil as a class II medication due to its low solubility and bioavailability. Candesartan Cilexetil nanosuspensions were made using antisolvent precipitation-ultrasonication and an alternate solvent. Drug solubility has improved with this method. The antisolvent volume is 1:15. Candesartan cilexetil nanosuspension was stabilised with PVP K-30. The Plackett-Burman design identified the main nanosuspension quality, stability, and efficiency element. The study examined mean particle size, saturation solubility, zeta potential, polydispersity index (PDI), cumulative percentage released (CPR) at two minutes, and percent weighted drug content using a 32-factorial design. We calculated the saturation solubility (µg/mL) and particle size (nm) of candesartan cilexetil nanosuspension batch CFD8 using mean ± standard deviation. Calculations showed values of 240.7 ± 8.3 and 113.03 ± 2.51. In vitro dissolution was performed on the unmilled suspension and commercial formulation.

Published: September 2024

This research aims to find out the background of Islamic education modernization, find out the urgency of Islamic education modernization, and find out the pattern of Islamic education modernization in the world. The method used in the preparation of this research is a qualitative method which in the data collection technique uses literature studies. The results of the analysis show that the background that is developing today in the modernization of Islamic education is the existence of internal and external factors. The internal factors are: 1) Muslims need a truly reliable Islamic education system in order to produce quality Muslim people, 2) the religion of Islam through the holy verses of the Qur'an tells and encourages Muslims to always think, and metaphorize; reading and analyzing everything to then be applied or even able to create new things from what has already existed. Meanwhile, the external factor that causes the importance of modernizing Islamic education is to catch up with Muslims against other nations, as well as to answer the challenges of changing times that are so dynamic. Meanwhile, the urgency of modernizing Islamic education is very important to invite third world nations that are still at the level of backwardness and backwardness to accept western standards that they consider to be ideal. And there are three patterns of modernization of Islamic education, namely: 1) Groups that are oriented towards the modern education pattern in the West. 2)  Islamic Education Modernization Movement (Renewal) oriented to pure Islamic sources. 3)  Educational reform efforts oriented to nationalism.

Objective: to compare 229 patients admitted to ICUs with COVID-19 and for other reasons, comparing the Functional Independence Measure-FIM after 3 months of discharge. Methodology: it is a cross-sectional study, with convenience sampling and a quantitative approach. 197 patients from the Adult-ICU and 32 from the ICU-COVID participated, at different times. Results: there were more older patients in the COVID-19 group than in the other (medians = 54.5 and 40 years; p = 0.000146). No difference was observed between genders, and patients with COVID-19 exhibited more comorbidities. There was no difference between ICU and mechanical ventilation days, but the “p” values ​​were close to significant. Patients with COVID-19 had a median time of 9 days in the ICU and 7 days on MV, and those hospitalized for other causes, 6 days in the ICU and 1.9 days on MV. Genders were equally distributed, but hypertensive and diabetic patients were more numerous in the group with COVID-19 (p < 0.0001). There was no evidence of difference in functional capacity between the groups, with locomotion, sphincter control and communication being the most affected. Comparison of the FIM percentages after 3 months of discharge showed no differences, however the average values ​​indicated complete rehabilitation for both groups. Conclusion: some results were corroborated by the literature, but should be interpreted with caution due to the low number of patients admitted to ICUs due to COVID-19 and the absence of FIM at the beginning of hospitalization and after discharge.

Published: September 2024

The new ceramic composites are 0.98 (NaNbO3)-0.02 Bi0.45Gd0.05K0.5Zr0.7Ti0.3O3 and 0.85 (NaNbO3)-0.15 Bi0.45Y0.04K0.5Zr0.7Ti0.3O3. Lead-free and polycrystalline were created using the traditional solid-state technique and have been widely researched for their various applications. Their manufacturing was accomplished through the use of a two-step sintering method. A perovskite structure with a Pmc21 space group was discovered to be present in the material when it was subjected to analysis. This was accomplished by utilising Schecher's formula and Williamson-Hall plots derived from XRD spectra in order to determine the particle size and strain. According to the results of the Raman spectroscopy, the vibrational spectral lines have shifted to a lower frequency, with the frequency range falling between 100 and 800 cm-1. Furthermore, the grain morphology was clearly characterised and varied in the FE-SEM pictures which were obtained. Band structure values were observed in the UV-Vis spectrum, and they ranged from 3.2 eV to 2.8 eV. There were emission bands in the green (522 nm), yellow (575 nm), and red (693 nm) ranges that were observed in the photoluminescence spectrum. The data from the dielectric material demonstrated a decrease in symmetry at temperatures ranging from 10 kHz to 1 MHz. In addition, the ferroelectric and piezoelectric coefficients were improved as a result of increasing doping, with d33 values of 150 (pc/N) and 255 (pc/N) respectively.

Ovaj rad predstavlja nastavak prethodnih istraživanja o mogućnosti klasifikacije uzoraka zvuka rada motora sa unutrašnjim sagorevanjem u dve različite klase prema tipu pogonskog goriva. Istraživanje uvodi novi pristup koji uključuje mapiranje zvuka u sliku, pri čemu se primenjuje A-ponderisanje uzoraka. Kako A-težinski filtar uobličava signal na sličan način kako se to radi u ljudskom čulu sluha, cilj upotrebe ovog filtra je omogućiti bolje prepoznavanje subjektivnih karakteristika u uzorcima zvuka, čime se generalno unapređuje mogućnost razlikovanja motora prema pogonskom gorivu. Dobijeni rezultati pokazuju da upotreba A-ponderisanih uzoraka značajno poboljšava diferencijaciju između klasa motora (zvuka) na osnovu izraženijih i značajnijih razlika između slika. Povećanje razlika u parametrima zvuka između klasa predstavljaju značajan potencijal za unapređenje tačnosti nadzirane klasifikacije. Obzirom da se koristi klasifikacija koja treba da simulira perceptivno razlikovanje motora, integracija A-ponderisanja u predobradu signala usklađuje pristup primenjenog mašinskog učenja sa ljudskom percepcijom. Rezultati istraživanja ističu efikasnost i potencijal A-ponderisanja uzoraka zvuka pre mapiranju u slike u klasifikacionim algoritmima mašinskog/dubokog učenja,

Intenzivna stanogradnja u Srbiji uslovila je otvaranje velikog broja novih samoposluga smeštenih u prizemlju novih stambenih zgrada. Njihovom otvaranju prethodi proces projektovanja u kome se definišu unutrašnja organizacija, enterijer i svi potrebni mašinski i elektro servisi. Kroz rad na projektovanju više samoposluga prepoznata je jedna specifična akustička dimenzija koja utiče na zvučni komfor ljudi u samoposluzi, zaposlenih i kupaca, ali i ljudi u stanovima iz neposrednom okruženju. Pokazalo se da projektantima nedostaju neke značajne informacije čiji nedostatak može dovesti do dve vrste grešaka u projektu. S jedne strane do nepotrebnog predimenzionisanja akustičkih intervencija, a s druge do nedovoljnih mera zvučne zaštite. Predimenzionisanje podrazumeva projektovanje suviše intenzivne zvučne izolacije prema najbližim stanovima i prekomernog ulaganja u akustičku obradu prostora, što donosi investitoru nepotrebne troškove. Nedovoljne mere zvučne zaštite nastaju kada se potceni značaj nekih zvučnih izvora u samoposluzi za zvučni komfor u okruženju. U ovom radu su prikazani rezultati merenja stanja ambijentalne buke u toku rada samoposluga i merenja vremena revrberacije u njima. To su podaci na osnovu kojih u projektima samoposluga treba da se dimenzioniše zvučna zaštita i akustička obrada.

Projektovanje i realizacija uzemljivačkog sistema na način da zadovolje željene karakteristike neretko zahteva i analizu uticaja nehomogenosti tla na karakteristike uzemljenja. Ponekada je moguće prisutnu nehomogenost tla aproksimirati kao vertikalni cilindrični domen. Takve nehomogenosti su razne cevi, bunari ili temelji stubova. U ovom preglednom radu objedinjeni su ranije izloženi rezultati primene postupka modelovanja nehomogenosti tla pomoću višeslojnog cilindričnog domena. Pristup je zasnovan na primeni Metoda momenata i odgovarajuće Grinove funkcije za cilindrični domen. Primena opisane procedure ilustrovana je na slučaju horizontalne elektrode u okolini cilindrične nehomogenosti kao i na problemu vertikalne elektrode u blizini bunara sa betonskim cilindričnim omotačem.

Cilj ovog rada je da istraži uticaj postojanja negausovog šuma u merenjima na performanse estimatora stanja u distributivnim mrežama. Uticaj je ispitivan na primeru dva različita estimatora stanja: WLS (Weighted Least-Squares), koji je zasnovan na primeni metoda minimuma sume otežanih kvadrata odstupanja, i EKF (Extended Kalman Filter), koji je zasnovan na primeni Kalmanovog filtra. Performanse svakog od estimatora su poređene za slučaj kada šum merenja podleže Gausovoj ili nekoj od negausovih raspodela verovatnoće, kao što su: Uniformna, Laplasova, Vejbulova i model Gausove smeše sa dve Gausove komponente. Analize su sprovedene na modifikovanom IEEE test sistemu sa 37 čvorova pri različitim pogonskim uslovima, uključujući kvazistacionarni režim, iznenadne promene stanja i loša merenja. Izvedeni su glavni zaključci i predložena su rešenja za prevazilaženje potencijalnih problema u radu estimatora.

U radu je prikazana mogućnost realizacije filtara propusnika opsega učestanosti koji ne reflektuju signale u nepropusnom osegu već ih apsorbuju. Apsorpcija neželjenih RF signala se realizuje sa širokopojasnim prilagođenjem pomoću četvrttalasnih ogranaka i memristorom. Prilagođenje se realizuje na ulazu filtara. Prikazana je i mogućnost podele propusnog opsega filtra na više podopsega, što omogućava veću fleksibilnost pri projektovanju. Kao primer realizacije prikazan je filtar sa pet propusnih opsega u mikrotrakastoj tehnici.

Savremena civilizacija ima već odavno svoju bogatu tehničku heritologiju. Sa inžinjerskim prilazom postoji bezbroj načina transformacija energije raznih vidova, što pripada i sa tehničke strane veoma složenoj problematici. Industrijske revolucije su na svoj način pratile i metode transformacije energije od fundamentalnih energetskih vidova za opstanak civilizacije do savremenih masmedija delatnosti. Putevi su bili sa jedne strane ka minijaturizaciji savremenih sistema, a sa druge strane se radilo o kapitalnim industrijskim kompleksima. Menjani su i trendovi. Strujni transformator kao statički električni uređaj funkcioniše na principu elektromagnetne indukcije. U zadacima elektromagnetske sprege i prenosima energije sa niskonaponske na visokonaponsku stranu i obrnuto, nalazi se niz problema koji su rešavani na bazi Faradejevih zakona. U izboru mnogobrojnih razvijenih transformatora od mikroskopsih dimenzija, gde se pojavljuju problemi trimovanja, do makroskopskih uređaja (nekoliko tona), nalazili su se zadaci ne samo prirode rada i odabira materijala jezgra, i tipova namotaja, do mehaničkih termodinamičkih, akustičkih, ekoloških i drugih osobina, uključujući i njihovo uklapanje u ambijent, gde se nalaze. Za pitanja bezbednosti za osoblje koje radi sa njim i posetilaca postrojenja, sigurno da su nezaobilazne mere bezbednosti sa nekoliko aspekata zaštite. Gubici transforamtora su posebno složena oblast s obzirom na njihovu prirodu ili drugi način podele. Metodi merenja koji kontrolišu razne režime rada transformatora i njihovo stanje od prvobitnog puštanja u pogon do kraja radnog veka su posebna oblast, koja je ujedinila razne vrste deskripcije karakteristika koje su po prirodi, uslovno električna, optička sa savremenom podelom na metode nekoherentne i koherentne tehnike. Ovaj rad analizira savremenu aktuelnu problematiku u oblasti transformatora sa izabranim studijama slučaja i sa uključenjem različitog ugla gledanja na materijale za transformatore i na brze metode kojima se može posle modelovati dati eksperiment sa uključenjem raznih oblasti: veze transformatora sa laserskom tehnikom.

U ovom radu zasnovanom na geometrijskim pravilnostima arhitektonskog dizajna, istražuju se mogućnosti načina kreiranja digitalnih parametarskih modela portala crkava u Raškoj (srednjevekovna teritorija Srbije). U literaturi, ovi portali su prepoznati kao romanički, prema karakterističnom dizajnu i geometriji. Rad je nastavak istraživanja autora na analizama šest izabranih portala, u kontekstu njihovog arhitektonskog dizajna i geometrije. Na osnovu definisanih dimenzionih parametara i geometrije oblika elemenata jednog portala, kreirani su odgovarajući 3D modeli elemenata, kroz nekoliko faza, obradom u različitim programskim paketima. Kroz modelovanje izabranog portala pokazan je postupak koji kombinuje tri programska paketa: AutoCAD, SolidWorks i ArchiCAD. Cilj rada je doprinos u sferi kreiranja digitalnih biblioteka elemenata izabranog tipa portala, u okviru Heritage Building Information Modelling-a (HBIM-informaciono modelovanje istorijskih objekata).

U odnosu na druge kategorije materijala, keramički materijali mogu da predstavljaju klasu materijala koja je za eksperimente teža, s obzirom na gabarite, poštovanje modela sličnosti, velike gustine. Zato se i tehnologije i merne tehnike, kojima se podvrgavaju odlikuju istim problemima. Iako se već mnogo godina koriste razne grane laserskih tehnika za različite keramičke materijale, u radu se razmatra nekoliko mogućih metoda, koje su već standardizovane u kontekstu keramike. Analiziraju se i potencijalno druge, koje se tek razvijaju. Uključuje se sprega sa drugim elionskim tehnikama, računajući proširenje sa akustikom, vodenim mlazevima, i dr. Sofisticirane tehnike brzih dejstava sa uključenjem nekada „brzih“ kamera, sada su se promenile za više redova veličine u odnosu na nekadašnje prve holograske kamere. Na primerima nekoliko keramičkih materijala i početnim komponentama u vidu prahova, proširuje se oblast ulaženja u procese sinterovanja i druge tehnologije. Uz primenu optičkih vlakana i metoda sa njihovom ugradnjom u karakterističke oblike, modele, olakšava se praćenje i uopšte dobijaju kvantitativni pokazatelji u dinamici naprezanja.

Effects of a Caffeine-Containing Transdermal Energy Patch on Aerobic and Anaerobic Exercise Performance
Authors: Dragoo Kenneth , Silvers Matthew , Johnson Kelly , Gonzalez Eliseo

The use of caffeine-containing (74-mg) energy patches (EnP) offers a novel mode of caffeine delivery that may alleviate stomach discomfort associated with oral caffeine use. The purpose of this study was to use four separate tests to evaluate the effects of EnP use on aerobic and anaerobic exercise performance. Three separate moderately active college-aged sample populations performed either 1) cycle time-to-exhaustion, 2) Wingate (WIN), or 3) repeated sprints and one repetition maximum bench press using EnP and placebo patches (PlP). No statistical differences were found between EnP and PlP for all dependent variables (p > 0.05) except for WIN peak power, which showed a statistically significant decrease (p = 0.04). The dose of caffeine topically applied via an EnP may not have been enough to elicit an ergogenic effect on exercise performance. A dose greater than 74-mg caffeine may be needed to produce an ergogenic effect. Further research is needed to investigate the delivery kinetics of transdermal caffeine in large dosages along with blood caffeine concentrations during and after exercise.
