Necrotizing Fasciitis Causing Complete Femoral Vessels Necrosis and Thrombosis in an Intravenous Drug Abuser: A Case Report
Authors: El Housseiny Majdi , Edriss Sirage , Kassar Talal , Abtar Houssam Khodor , Terro Jad J 
Published: May 2021

Background: Intravenous drug abuse is an anciently known health and social problem worldwide. The nonsterile application of addicting drugs leads to severe life-threatening vascular complications. The femoral triangle is an easy target for this purpose. Groin necrotic fasciitis (NF) with vessel necrosis is a challenging diagnosis that requires prompt treatment.
Case Report: A 44-year-old male intravenous drug user presented for a left groin pain. He was diagnosed by computed tomography scan to have necrotizing fasciitis. Urgent debridement was performed and identified infected and necrotic ruptured femoral vessels without active bleeding. Debridement with vessel ligation was performed, and delayed revascularization was planned. The patient was admitted six weeks later with a left fifth toe necrosis and delayed arterial revascularization was performed via extra-anatomic trans-obturator ilio-femoral anastomosis. The patient had a favorable follow-up.
Conclusion: NF in intravenous drug abusers should always be taken into consideration when a patient presents with groin pain and swelling. Urgent surgical control should be established. Extra-anatomical trans-obturator ilio-femoral anastomosis is a good option for revascularization.
Detectable Data-driven Features in the Primordial Scalar Power Spectrum

Published: May 2021

Abstract
In this work we explore the power of future large-scale surveys to constrain possible deviations from the standard single-field slow-roll inflationary scenario. Specifically, we parameterize possible fluctuations around the almost scale-invariant primordial scalar power spectrum in a model-independent way. We then use their imprints on the simulated matter distribution, as observed by the galaxy clustering and weak lensing probes of Euclid and the Square Kilometer Array, to construct the best constrainable patterns of fluctuations. For comparison, we make similar forecasts for a futuristic CMB-S4-like survey. The modes are found to have similar, yet shifted, patterns, with increasing number of wiggles as the mode number increases. The forecasted constraints are tightest for cosmic microwave background anisotropies and galaxy clustering, depending on the details of the specifications of the survey. As case studies, we explore how two greatly different physically motivated patterns of primordial power spectrum are reconstructed by the proposed modes. We propose a figure of merit based on the amount of information delivered by the modes to truncate the mode hierarchy, which is automatically generated by the analysis.
What Causes Faint Solar Coronal Jets from Emerging Flux Regions in Coronal Holes?
Authors: Harden Abigail R. , Panesar Navdeep K. , Moore Ronald L. , Sterling Alphonse C. , Adams Mitzi L. 
Published: May 2021

Abstract
Using EUV images and line-of-sight magnetograms from Solar Dynamics Observatory, we examine eight emerging bipolar magnetic regions (BMRs) in central-disk coronal holes for whether the emerging magnetic arch made any noticeable coronal jets directly, via reconnection with ambient open field as modeled by Yokoyama & Shibata. During emergence, each BMR produced no obvious EUV coronal jet of normal brightness, but each produced one or more faint EUV coronal jets that are discernible in AIA 193 Å images. The spires of these jets are much fainter and usually narrower than for typical EUV jets that have been observed to be produced by minifilament eruptions in quiet regions and coronal holes. For each of 26 faint jets from the eight emerging BMRs, we examine whether the faint spire was evidently made a la Yokoyama & Shibata. We find that (1) 16 of these faint spires evidently originate from sites of converging opposite-polarity magnetic flux and show base brightenings like those in minifilament-eruption-driven coronal jets, (2) the 10 other faint spires maybe were made by a burst of the external-magnetic-arcade-building reconnection of the emerging magnetic arch with the ambient open field, with reconnection directly driven by the arch's emergence, but (3) none were unambiguously made by such emergence-driven reconnection. Thus, for these eight emerging BMRs, the observations indicate that emergence-driven external reconnection of the emerging magnetic arch with ambient open field at most produces a jet spire that is much fainter than in previously reported, much more obvious coronal jets driven by minifilament eruptions.

Published: May 2021

In this study, various treated, untreated, and treated kenaf/glass fiber composites were fabricated using epoxy resin. A portion of kenaf fibers were subjected to treatment with alkali, sub-portion was taken for benzoyl peroxide and potassium permanganate prior to composite fabrication. This treatment on the composite material was undertaken to achieve improved modification of the interface between the matrix and fiber bond. A portion of the glass fiber was used for enhancing the mechanical properties of the hybrid composite. The tensile strength, flexural, density, water absorption and chemical resistance of the composites were analyzed using standard methods. FTIR was conducted on the fiber to ascertain the chemical treatment on the fibers, FESEM was used for the morphological study. The results obtained showed that the tensile and flexural strength improved from 46.45-298.3 kgf, and 10.5-54.7 kgf, respectively, in the composite samples. Chemical resistance of the kenaf fiber treated potassium permanganate composite improved compared to the untreated fiber composite in both cases. The density and water absorption properties of the composites were found to decrease in the treated fibers compared to untreated fiber composites, this treated composites showed less water absorption and density. The FTIR result revealed that reaction has taken place between the fiber and the treatment reagent. Hence, fiber modification has improved the properties of the composites due to increase in fiber-matrix interaction.

Published: May 2021

This study evaluated the effect of participation in factory contracted services on the profitability of smallholder sugarcane farmers inMalava Sub-county in Western Kenya. Primary data were collected using structured questionnaire from a sample of 384 farmers usingsystematic random sampling and proportionate sampling. Analysis of variance was applied to determine if there was a significant difference between profitability of contracted and non-contracted farmers. The effect of contracted services on profitability among contract farmers was analyzed by multiple linear regression. The results showed that contracted extension, labour and credit services had significant effect on farmers’ gross margins. The Kenyan government should formulate policies that enhance provision of contracted extension, labour and credit services. The need for a review of the existing contract engagement terms among sugarcane farmers is also evident in this study.

The study provided an empirical evidence on the use of improved goat production technologies among rural farmers in Abia State, Nigeria. The specific objectives of the study were, ascertain the extent of use of improved goat production technologies, determine factors influencing use of improved goat production technologies and identify constraints to access and use of improved goat production technologies. A multi-stage random sampling procedure was adopted in selecting 120 respondents. Data were collected through the use of questionnaire and analysed with frequency, percentage, mean and regression model. Respondents were aware of dipping (100%),deworming (99.2%) fostering of kids (93.3%) and colostrum feeding (71.7%), among others. On extent of use of improved goat production technologies, respondents highly used most of improved goat production technologies [grand mean = X̄ = 3.20]. All the respondents [100%] agreed that lack of access to credit was a constraint to use, 100% agreed on lack of credibility from source of technological information, 99.2% agreed that they were afraid of taking risk, 93.3% agreed on difficulty in technology application, among others. Age education, household size, farming experience, farm size, income and access to credit were the determinants of use of improved goat production technologies at 5% level of probability Greater use of available improved technologies will promote productivity, and therefore there is need for proper sensitization and awareness by relevant agencies. Again, credit should be made available to farmers by relevant governmental and nongovernmental agencies to increase the level of use of available improved technologies.
