Improving the PrEP care continuum: a program evaluation
Creators: name: Louis-Jacques, Carmel
Publisher: name: No Publisher Supplied
Year: 2021

description: Background: Nearly 30 years after the initial cases of human immunodeficiency virus in the United States, the Food and Drug Administration (FDA) approved the first drug for the prevention of sexually acquired HIV. Although robust evidence supports the use of Pre-exposure Prophylaxis (PrEP) in high-risk populations only 12% of this population have received PrEP (CDC, 2020).Purpose: The overall aim of this quality improvement (QI) project was to evaluate the impact of a PrEP program in an urban community based sexual health clinic serving an ethnically diverse population.Method: A retrospective chart review of all patients enrolled in the health center’s PrEP program between 2019-2020 was conducted. A total of 92 charts were reviewed. Data retrieved was analyzed using descriptive statistics. Findings identified barriers to care and recommendations to improve the efficacy of the program on the patient, provider and stakeholder level were offered to the clinic.Results: Data analyzed found that of the 92 patients eligible for PrEP, 90 were enrolled in the PrEP program. Most participants were Hispanic males aged 31 to 40 years old. Adherence to the recommended follow-up visits decreased with time. At the 3-month visit, 72 of the original 90 patients kept their appointment. This number decreased to 58, 56 and 53 patients at the 6-,9-,12- month follow up appointment, respectively. Regarding sexually transmitted infections (STIs), 68 patients were diagnosed with other STIs. Discontinuation was relatively low, with 19% of participants discontinuing PrEP. One patient relocated and followed up at a different clinic and one patient declined PrEP. Reasons for discontinuing PrEP were not identified per the charts reviewed for the remaining patients.Implication for practice: This project served as a benchmark for evaluating future PrEP programs. The findings of this QI project set forth recommendations to improve adherence to PrEP and in turn lessen the incidence of HIV. Such recommendations include expanding the demographic data to include patients, gender and preferred sexual orientation; the use of EMR or Patient Portal reminders; interactive text messages, and patient reminders; use of telehealth and telemedicine; and addressing patients where they are in terms of other life circumstances. It is imperative for stakeholders to have a thorough understanding of the facilitators and barriers to PrEP. By doing so, they will maximize its benefits while potential PrEP candidates will be enrolled and retained in care.

description: The ability to control and direct acoustic energy is essential for many engineering applications such as vibration and noise control, invisibility cloaking, acoustic sensing, energy harvesting, and phononic switching and rectification. The realization of acoustic regulators requires overcoming fundamental challenges inherent to the time-reversal nature of wave equations. Typically, this is achieved by utilizing either a parameter that is odd-symmetric under time-reversal or by introducing passive nonlinearities. The former approach is power consuming while the latter has two major deficiencies: it has high insertion losses and the outgoing signal is harvested in a different frequency than that of the incident wave due to harmonic generation. Here, we adopt a unique approach that exploits spatially distributed linear and nonlinear losses in a fork-shaped resonant metamaterial. Our compact design demonstrates asymmetric acoustic reflectance and transmittance, and acoustic switching. In contrast to previous studies, our non-Hermitian metamaterial exhibits asymmetric transport with high frequency purity of the outgoing signal.

description: We present observations of 50 pairs of redshift z ~ 0.2 star-forming galaxies and background quasars. These sightlines probe the circumgalactic medium (CGM) out to half the virial radius, and we describe the circumgalactic gas kinematics relative to the reference frame defined by the galactic disks. We detect halo gas in MgII absorption, measure the equivalent-width-weighted Doppler shifts relative to each galaxy, and find that the CGM has a component of angular momentum that is aligned with the galactic disk. No net counter-rotation of the CGM is detected within 45 degrees of the major axis at any impact parameter. The velocity offset of the circumgalactic gas correlates with the projected rotation speed in the disk plane out to disk radii of roughly 70 kpc. We confirm previous claims that the MgII absorption becomes stronger near the galactic minor axis and show that the equivalent width correlates with the velocity range of the absorption. We cannot directly measure the location of any absorber along the sightline, but we explore the hypothesis that individual velocity components can be associated with gas orbiting in the disk plane or flowing radially outward in a conical outflow. We conclude that centrifugal forces partially support the low-ionization gas and galactic outflows kinematically disturb the CGM producing excess absorption. Our results firmly rule out schema for the inner CGM that lack rotation and suggest that angular momentum as well as galactic winds should be included in any viable model for the low-redshift CGM.

description: For distinguishable particles it is well known that Brownian motion and a Feynman-Kac functional can be used to calculate the path integral (for imaginary times) for a general class of scalar potentials. In order to treat identical particles, we exploit the fact that this method separates the problem of the potential, dealt with by the Feynman-Kac functional, from the process which gives sample paths of a non-interacting system. For motion in 1 dimension, we emphasize that the permutation symmetry of the identical particles completely determines the domain of Brownian motion and the appropriate boundary conditions: absorption for fermions, reflection for bosons. Further analysis of the sample paths for motion in 3 dimensions allows us to decompose these paths into a superposition of 1-dimensional sample paths. This reduction expresses the propagator (and consequently the energy and other thermodynamical quantities) in terms of well-behaved 1-dimensional fermion and boson diffusion processes and the Feynman-Kac functional.

description: The perturbation theory expansion presented earlier to describe the phase-ordering kinetics in the case of a nonconserved scalar order parameter is generalized to the case of the $n$-vector model. At lowest order in this expansion, as in the scalar case, one obtains the theory due to Ohta, Jasnow and Kawasaki (OJK). The second-order corrections for the nonequilibrium exponents are worked out explicitly in $d$ dimensions and as a function of the number of components $n$ of the order parameter. In the formulation developed here the corrections to the OJK results are found to go to zero in the large $n$ and $d$ limits. Indeed, the large-$d$ convergence is exponential.

description: Employing elastic and inelastic neutron scattering (INS) techniques, we report on detailed microscopic properties of the ferromagnetism in he magnetic topological insulator (Bi$_{0.95}$Mn$_{0.05}$)$_{2}$Te$_{3}$. Neutron diffraction of polycrystalline samples show the ferromagnetic (FM) ordering is long-range within the basal plane, and mainly 2D in character with short-range correlations between layers below $T_{\mathrm{C}} \approx 13$ K. Despite the random distribution of the dliute Mn atoms, we find that the 2D-like magnetic peaks are commensurate with the chemical structure, and the absence of (00L) magnetic peaks denote that the Mn$^{2+}$ magnetic moments are normal to the basal planes. Surprisingly, we observed collective magnetic excitations, in this dilute magnetic system. Despite the dilute nature, the excitations are typical of quasi-2D FM systems, albeit are severely broadened at short wavelengths, likely due to the random spatial distribution of Mn atoms in the Bi planes. Detailed analysis of the INS provide energy scales of the exchange couplings and the single ion anisotropy.
Flare Productivity of Major Flaring Solar Active Regions: A Time-series Study of Photospheric Magnetic Properties

description: A solar active region (AR) that produces at least one M- or X-class major flare tends to produce multiple flares during its passage across the solar disk. It will be interesting if we can estimate how flare-productive a given major flaring AR is for a time interval of several days, by investigating time series of its photospheric magnetic field properties. For this, we studied 93 major flaring ARs observed from 2010 to 2016 by the Helioseismic and Magnetic Imager (HMI) on board the Solar Dynamics Observatory (SDO). More specifically, for each AR under study, the mean and fluctuation were calculated from an 8-day time series of each of 18 photospheric magnetic parameters extracted from the Space-weather HMI Active Region Patch (SHARP) vector magnetogram products at 12-min cadence. We then compared these with the AR's 8-day flare index, which is defined as the sum of soft X-ray peak fluxes of flares produced in the AR during the same interval of the 8-day SHARP parameter time series. As a result, it is found that the 8-day flare index is well correlated with the mean and/or fluctuation values of some magnetic parameters (with correlation coefficients of 0.6-0.7 in log-log space). Interestingly, the 8-day flare index shows a slightly better correlation with the fluctuation than the mean for the SHARP parameters associated with the surface integral of photospheric magnetic free energy density. We also discuss how the correlation varies if the 8-day flare index is compared with the mean or fluctuation calculated from an initial portion of the SHARP parameter time series.

description: Jet substructure variables for hadronic jets with transverse momenta in the range from 2.5 TeV to 20 TeV were studied using several designs for the spatial size of calorimeter cells. The studies used the full Geant4 simulation of calorimeter response combined with realistic reconstruction of calorimeter clusters. In most cases, the results indicate that the performance of jet-substructure reconstruction improves with reducing cell size of a hadronic calorimeter from $Δη\times Δϕ= 0.087\times0.087$, which are similar to the cell sizes of the calorimeters of LHC experiments, by a factor of four, to $0.022\times0.022$.

description: A K-matrix re-analysis of the K-pi S-wave is performed in the mass region 900-2100 MeV, and solutions which describe the data well are found. The solution with two resonances in the (IJ^P=1/2 0^+)-wave has poles at (1415 pm 25)- i(165 pm 25) MeV and (1820 pm 40) -i(125 pm 50) MeV, close to the previous result of D. Aston et al., Nucl.Phys., B296 (1988) 493. The corresponding bare states, which are the subjects of a qqbar classification, are: K_0^{bare}(1220^{+50}_{-60}) and K_0^{bare}(1885^{+50}_{-80}). Within the restored bare states, a construction of the 1^3P_0 qqbar and 2^3P_0 qqbar nonets is completed. The three resonance solutions are analysed as well, the corresponding bare states are found, and the qqbar-nonet classification is suggested. In all variants of our qqbar-classification, the resonances a_0(980) and f_0(980) (or their bare counterparts) are non-exotic, and an extra scalar/isoscalar state exists in the mass region 1300-1700 MeV, being a good candidate for the lightest scalar glueball.

description: Dynamic magnetic properties of $\mathrm{Y_{0.7}Ca_{0.3}MnO_{3}}$ are reported. The system appears to attain local ferromagnetic order at $T_{\mathrm{SRF}} \approx 70$ K. Below this temperature the low field magnetization becomes history dependent, i.e. the zero field cooled (ZFC) and field cooled (FC) magnetization deviate from each other and closely logarithmic relaxation appears at our experimental time scales (0.3-$10^{4}$ sec). The zero field cooled magnetization has a maximum at $T_{\mathrm{f}}\approx 30$ K, whereas the field cooled magnetization continues to increase, although less sharply, also below this temperature. Surprisingly, the dynamics of the system shows non-equilibrium spin glass (SG) features not only below the maximum in the ZFC magnetization, but also in the temperature region between this maximum and $T_{\mathrm{SRF}}$. The aging and temperature cycling experiments show only quantitative differences in the dynamic behavior above and below the maximum in the ZFC-magnetization; similarly, memory effects are observed in both temperature regions. We attribute the high temperature behavior to the existence of clusters of short range ferromagnetic order below $T_{\mathrm{SRF}}$; the configuration evolves into a conventional spin glass state at temperatures below $T_{\mathrm{f}}$.

description: In the present study, experiments on thermal decomposition of several kerosene fuels (Jet A-1, indoor kerosene, YK-D80N) were performed. Three kerosene fuels have different aromatic and sulfur contents. Jet A-1 has largest sulfur content and YK-D80N has almost no sulfur. For thermal decomposition tests, the cooling specimens with inner copper alloy and outer stainless steel were designed and manufactured. Each kerosene fuel was heated above 670 K. For Jet A-1, coking did not occur at 600 K but took place at 670 K. For indoor kerosene and YK-D80N, coking phenomenon was not found at 670 K. Specially, YK-D80N was heated up to 720 K and was stable for one hour test. From the tests, it is confirmed that sulfur content is an important factor affecting coking limit temperature.

description: We analyze a 3D hydrodynamic simulation of common envelope evolution to understand how energy is transferred between various forms and whether theory and simulation are mutually consistent given the setup. Virtually all of the envelope unbinding in the simulation occurs before the end of the rapid plunge-in phase, here defined to coincide with the first periastron passage. In contrast, the total envelope energy is nearly constant during this time because positive energy transferred to the gas from the core particles is counterbalanced by the negative binding energy from the closer proximity of the inner layers to the plunged-in secondary. During the subsequent slow spiral-in phase, energy continues to transfer to the envelope from the red giant core and secondary core particles. We also propose that relative motion between the centre of mass of the envelope and the centre of mass of the particles could account for the offsets of planetary nebula central stars from the nebula's geometric centre.

description: We study the onset of chaos due to temporal and spatially periodic perturbations in charged Gauss-Bonnet AdS black holes in extended thermodynamic phase space, by analyzing the zeros of the appropriate Melnikov functions. Temporal perturbations coming from a thermal quench in the unstable spinodal region of P-V diagram, may lead to chaos, when a certain perturbation parameter $γ$ saturates a critical value, involving the Gauss-Bonnet coupling $α$ and the black hole charge $Q$. A general condition following from the equation of state is found, which can rule out the existence of chaos in any black hole. Using this condition, we find that the presence of charge is necessary for chaos under temporal perturbations. In particular, chaos is absent in neutral Gauss-Bonnet and Lovelock black holes in general dimensions. Chaotic behavior continues to exist under spatial perturbations, irrespective of whether the black hole carries charge or not.

description: This study attempts to derive numerically the shell Knockdown factors of isogrid-stiffened cylinders under axial compressive loads. Various shell thickness ratios are considered for the isogrid-stiffened cylinders. Two different modeling techniques such as the detailed modeling with numerous stiffeners and the equivalent modeling without modeling of stiffeners are applied for the present work. The single perturbation load approach (SPLA) is used to represent the geometrical initial imperfection of a cylinder. Postbuckling analyses with the displacement control method are conducted to derive numerically the shell Knockdown factors of isogrid-stiffened cylinders. The global buckling loads and shell Knockdown factors using the equivalent model are excellently compared with the results with the detailed model although the computation time using the equivalent model is 13 to 16% of that with the detailed model. The present Knockdown factor function in terms of the shell thickness ratio for the isogrid-stiffened cylinder is much higher than NASA\'s Knockdown factor function; therefore, it is believed that the present Knockdown factor function can facilitate in developing lightweight launch vehicle structures using the isogrid-stiffened cylinder.

description: Multidrug resistance resulting from a variety of defensive pathways in cancer has become a global concern with a considerable impact on the mortality associated with the failure of traditional chemotherapy. Therefore, further research and new therapies are required to overcome this challenge. In this work, a cyclic R10 peptide (cR10) is conjugated to polyglycerol‐covered nanographene oxide to engineer a nanoplatform for the surmounting of multidrug resistance. The nuclear translocation of the nanoplatform, facilitated by cR10 peptide, and subsequently, a laser‐triggered release of the loaded doxorubicin result in efficient anticancer activity confirmed by both in vitro and in vivo experiments. The synthesized nanoplatform with a combination of different features, including active nucleus‐targeting, high‐loading capacity, controlled release of cargo, and photothermal property, provides a new strategy for circumventing multidrug resistant cancers.

description: The free energy of the Coulomb Gap problem is expanded as a set of Feynman diagrams, using the standard diagrammatic methods of perturbation theory. The gap in the one-particle density of states due to long-ranged interactions corresponds to a renormalization of the two-point vertex function. By collecting the leading order logarithmic corrections we have derived the standard result for the density of states in the critical dimension, d=1. This method, which is shown to be identical to the approach of Thouless, Anderson and Palmer to spin glasses, allows us to derive the strong-disorder behaviour of the density of states. The use of the renormalization group allows this derivation to be extended to all disorders, and the use of an epsilon-expansion allows the method to be extended to d=2 and d=3. We speculate that the renormalization group equations can also be derived diagrammatically, allowing a simple derivation of the crossover behaviour observed in the case of weak disorder.

description: В современных компьютерных сетях большую роль играют системы маршрутизации. Плохо организованная работа маршрутизатора приводит к снижению производительности сети и возникновению сбоев. В этой связи при проектировании сетей к ним предъявляются строгие требования по обеспечению стабильной работы и должного качества обслуживания сетевого трафика. Можно выделить широкий круг алгоритмов маршрутизации в сети. Как правило, в их основе лежат методы дискретной математики. Однако в последнее время распространение получили алгоритмы, использующие методы интеллектуального анализа данных. Так, среди них можно выделить нейросетевые алгоритмы маршрутизации. Использование нейросетей как метода непараметрической оценки может придать интеллектуальный характер процессам сетевой маршрутизации. В этой связи для решения задачи маршрутизации предложено применение сетей Хопфилда. Их во многом уникальные свойства позволяют описать процесс маршрутизации в сети в терминах нейродинамики. Это позволяет свести традиционно комбинаторные задачи к задачам нелинейной оптимизации. Последнее обстоятельство позволяет существенно ускорить их решение. В статье предлагается решение задачи маршрутизации в сети с применением метода нейронной сети Хопфилда.
description: In modern computer networks, routing systems play an important role. Poorly organized operation of the router leads to a decrease in network performance and the occurrence of failures. In this regard, when designing networks, they are subject to strict requirements for ensuring stable operation and proper quality service of network traffic. You can select a wide range of routing algorithms in the network. As a rule, they are based on the methods of discrete mathematics. However, recently algorithms using data mining methods have become popular. So, among them are neural network routing algorithms. The use of neural networks as a nonparametric estimation method can add intellectual character to network routing processes. In this regard, the use of Hopfield networks has been proposed to solve the routing problem. Their many unique properties allow us to describe the process of routing in the network in terms of neurodynamics. This allows traditionally combinatorial problems to be reduced to nonlinear optimization problems. The latter circumstance can significantly speed up their decision. The article proposes a solution to the problem of routing in the network using the Hopfield neural network method.

Inverse scattering in Stark effect
Creators: name: Ishida, Atsuhide
Publisher: name: arXiv
Year: 2018
Subjects: subject: Mathematical Physics (math-ph)
subject: FOS: Physical sciences

description: We study one of the multidimensional inverse scattering problems for quantum systems governed by the Stark Hamiltonians. By applying the time-dependent method developed by Enss and Weder in 1995, we prove that the high-velocity limit of the scattering operator determines uniquely the short-range interaction potentials. Moreover, we prove that, when a long-range interaction potential is given, the high-velocity limit of the Dollard-type modified scattering operator determines uniquely the short-range part of the interactions. We allow the potential functions to belong to very broad classes. These results are improvements on the previous results obtained by Adachi and Maehara in 2007 and Adachi, Fujiwara, and Ishida in 2013.
Towards Secure Slicing: Using Slice Isolation to Mitigate DDoS Attacks on 5G Core Network Slices
Creators: name: Sattar, Danish

Subjects: subject: Networking and Internet Architecture (cs.NI)

description: In this paper, we propose a solution to proactively mitigate Distributed Denial-of-Service attacks in 5G core network slicing using slice isolation. Network slicing is one of the key technologies that allow 5G networks to offer dedicated resources to different industries (services). However, a Distributed Denial-of-Service attack could severely impact the performance and availability of the slices as they could share the same physical resources in a multi-tenant virtualized networking infrastructure. Slice isolation is an essential requirement for 5G network slicing. In this paper, we use network isolation to tackle the challenging problem of Distributed Denial-of-Service attacks in 5G network slicing. We propose the use of a mathematical model that can provide on-demand slice isolation as well as guarantee end-to-end delay for 5G core network slices. We evaluate the proposed work with a mix of simulation and experimental work. Our results show that the proposed isolation could mitigate Distributed Denial-of-Service attacks as well as increase the availability of the slices. We believe this work will encourage further research in securing 5G network slicing.
Changing the American lawn: a quest for normalizing lawn weeds
Creators: name: Ilkow, Daniel
Publisher: name: No Publisher Supplied
Year: 2021

description: The American lawn is a pertinent component of the natural landscape and plays a significant role in American culture. It is a major ideological component of the “correct” look of the American suburbs. Additionally, this desired aesthetic does not take into account its negative impacts on pollinators and the ecosystem as a whole. The American lawn is heavily controlled and manicured, often involving regimented and aggressive uses of pesticides, fertilizers, and mowing. These diminish the lawn’s ecological functions, as preference is given to maintaining societal norms. Despite these efforts to control, people must continually work to maintain their lawn in a desired condition, as it naturally fights back through innate ecological processes. I argue that it is crucial to loosen the reins on lawn care as well as to alter expectations of what a lawn “should” be in order to design and steward a more sustainable ecosystem for the future. This thesis examines fostering a more sustainable ecosystem and redefining the lawn in the American social context. The primary question to answer is how can the lawn be more sustainable by incorporating lawn weeds alongside of turf grasses in the American lawn? To answer this question, this paper explores how the lawn became a part of the cultural landscape in America. It then examines existing lawns on a broader scale and strategies for making their different uses more sustainable. The use of the suburban lawn is then addressed and broken down to the ecological level. This is done by addressing how lawn weeds fit into the ecosystem of the lawn. In the context of the New Jersey landscape, using scientific analysis and design strategies, this paper explores the process of diversifying the lawn to see how lawn weeds can function within the lawn and be presented in an aesthetically pleasing fashion.
Scattering on spin fluctuations in itinerant quantum disordered ferromagnets near quantum phase transition

description: Taking into account the long-ranged spin interactions due to weak localization effects in disordered itinerant ferromagnets the scattering of both electrons and neutrons on critical spin fluctuations near quantum phase transition is considered. It is shown that for the case of low electron density, when k_F ξ\ll 1, where k_F is the Fermi momentum and ξis the magnetic correlation length, the transport cross section of electrons is proportional to conventional critical fluctuations in absence of weak localization effects. However, the intensity of the multiple small-angle neutron scattering becomes exponentially small as compared with the intensity of the multiple scattering by conventional critical fluctuations.

Relativistic Fluctuations and Anomalous Darwin Terms in Superconductors

description: The anomalous Darwin term, one of the recently derived relativistic corrections to the conventional theory of superconductivity, is analysed in detail. A new derivation of this term, much simpler than that given originally, is presented and used to interpret the term physically, in terms of fluctuations of the relativistic wave packet describing the paired electrons. Several puzzling features of the original derivation find a simple explanation in terms of this reinterpretation. The question of observability of the anomalous Darwin term, and its relation to the conventional Darwin term and to earlier proposed superconducting Darwin terms are also discussed.
Spectroscopic study of two new super Li rich red clump K giants

description: In this paper, we report the discovery of two new super Li-rich K giants: HD~24960 and TYC~1751-1713-1. Based on high resolution ($R\approx 60,000$) spectroscopy, we have derived Li abundance of A(Li)$\approx$4.0~dex for both stars. Other elemental abundances are normal of typical K giants. Low ratios of [C/N] $\leq$ $-$ 0.25 and $^{12}C/^{13}C \leq10$ suggest that the stars are in upper RGB phase. Further, based on Gaia astrometry and secondary calibrations using Kepler asteroseismic and LAMOST spectroscopic data, we argue that both stars belong to red clump (RC) phase with core He-burning. Results add to half a dozen already known red clump Li-rich K giants, and support the growing evidence that the origin of Li excess in RC giants seems to be associated with either He-flash at the tip of the red giant branch (RGB) or recent planet/ brown dwarf merger events closer to the RGB tip.
How can academic libraries help support students’ mental health?
Creators: name: Hunter, Clare
Publisher: name: Reflective Professional
Year: 2021

description: The topic of mental health and wellbeing amongst students has become more and more widely discussed in recent years with a noticeable increase in students requesting mental health and wellbeing support. To try and meet this need many universities are trying a whole university approach to mental health and wellbeing where all sections of the university play a role in supporting the mental health and wellbeing of students. This poses the question of what role does the academic library play in this whole university approach? Despite a significant number of academic libraries already offering support there are significant gaps in the research into the attitudes and opinions of both academic library staff and university students towards academic libraries providing mental health and wellbeing support. The aim of the research was to investigate how academic libraries can positively impact on student mental health and wellbeing. This was done through a phenomenological mixed methods research which included student focus groups and a survey of UK academic library staff. The results of the student focus groups, and staff survey showed that both students and staff felt positively towards the idea of mental health and wellbeing support in libraries, however, both students and staff did express concerns about what the support would entail and how it would be enacted. Students gave a variety of suggestions for how the academic library could improve student mental health with library staff agreeing that these ideas would be effective. However, these proposals were not necessarily feasible for all academic libraries. Most staff survey respondents felt management support was there, but many lacked the funds, and staff time to support mental health and wellbeing of students. This research will contribute to best practice on how academic libraries provide mental health and wellbeing support.

description: River basins as diverse as the Nile, the Amazon, and the Mississippi satisfy certain topological invariants known as Horton's laws. Do these macroscopic (up to 10^3 km) laws extend to the micron scale? Through realistic simulations, we analyze the morphology and statistical properties of networks of vortex flow in flux-gradient-driven superconductors. We derive a phase diagram of the different network morphologies, including one in which Horton's laws of length and stream number are obeyed -- even though these networks are about 10^9 to 10^15 times smaller than geophysical river basins.

description: Abstract
Croton macrostachyus Delil belongs to one of the largest genera of the family Euphorbiaceae, called Croton under the subfamily Crotonoideae. The genus Croton is ecologically prominent, and an important source of secondary metabolites with antimicrobial properties in tropics and subtropics. The objective of this study was to test the antibacterial property of the leaf extract of Croton macrostachyus and a lauric acid derivative, Methyl Laurate, isolated from it. Crude extract was obtained through phytochemical screening using the solvent acetone.
