Published: September 2020

Peningkatan produksi dan reproduksi ternak akan optimal jika penyediaan pakan yang memadai dan pengendalian penyakit dilakukan secara efektif. Gangguan penyakit pada ternak dapat menurunkan produktivitas ternak. Penyakit yang biasanya menyerang ternak sapi adalah penyakit cacing. Penyakit ini tidak mengakibatkan kematian pada ternak, namun menyebabkan kerugian yang sangat besar karena menurunkan berat badan dan daya produktivitas hewan. Biji labu kuning telah lama digunakan sebagai antihelmintik. Penentuan efektivitas biji labu kuning sebagai obat cacing, maka dilakukan penelitian dengan memasukkan cacing sebanyak 10 ekor ke dalam cawan petri yang berisi infusa biji labu kuning dengan konsentrasoi yang berbeda, yaitu (P1): konsentrasi kandungan infusa biji labu kuning 25/100 ml, (P2): konsentrasi kandungan infusa biji labu kuning 50/100 ml, dan (P3): konsentrasi kandungan infusa biji labu kuning 75/100 ml. Hasil penelitian menunjukkan bahwa dengan konsentrasi infusa labu kuning sebesar 75% mampu membunuh semua cacing fasciola yang ada. Konsentrasi yang lebih rendah menunjukkan angka kematian sebesar 47% dan 77%. Dengan demikian dapat direkomendasikan bahwa penggunaan infusa labu kuning sebesar 75/100 ml.

Lipstik merupakan kosmetik yang sangat populer di kalangan wanita dan digunakan hampir oleh kebanyakan wanita setiap harinya. Produk lipstik yang baik selain untuk mempercantik warna bibir, diharapkan juga mampu memberikan nutrisi dan meningkatkan rasa percaya diri sehingga membuat bibir menjadi lebih sehat serta tidak mudah kering. Berdasarkan hal tersebut dapat mendorong dalam pengembangan produk lipstik secara back to nature. Ketersediaan lipstik hendaknya berasal dari bahan alam yang lebih menguntungkan dalam penggunaanya, salah satunya melalui penggunaan bahan susu. Disisi lain, hasil identifikasi kebanyakan menunjukan bahwa harga jual susu dikalangan peternak masih rendah. Dengan harga jual yang rendah tersebut cukup sulit bagi peternak memperoleh fisibilitas dari usaha yang dijalankannya. Penelitian ini bertujuan untuk mengetahui tingkat kelayakan usaha dari nilai tambah yang dihasilkan produk susu menjadi lipstik. Berdasarkan kegiatan produksi yang telah dilakukan dan hasil analisis diperoleh biaya produksi usaha sebesar Rp 2.247.500,00 menghasilkan penerimaan sebesar Rp 3.000.000,00 dan pendapatan 1.604.000,00. Nilai RC Ratio sebesar 2,14 (RC Ratio > 1), BC Ratio sebesar 1,14 (BC Ratio>1), serta nilai titik impas/Break Event Point (BEP) produksi sebesar 82 satuan dan Rp 24.491,22. Sehingga analisis kelayakan usaha terhadap produksi lipstik berbahan dasar susu dapat dinyatakan layak dan menguntungkan, dengan pertimbangan sesuia kriteria teknis dan variabel yang telah ditentukan.

Abstract
We construct an emulator for the halo mass function over group and cluster mass scales for a range of cosmologies, including the effects of dynamical dark energy and massive neutrinos. The emulator is based on the recently completed Mira-Titan Universe suite of cosmological N-body simulations. The main set of simulations spans 111 cosmological models with 2.1 Gpc boxes. We extract halo catalogs in the redshift range z = [0.0, 2.0] and for masses

}; spatial flatness is assumed. We obtain smooth halo mass functions by fitting piecewise second-order polynomials to the halo catalogs and employ Gaussian process regression to construct the emulator while keeping track of the statistical noise in the input halo catalogs and uncertainties in the regression process. For redshifts z ≲ 1, the typical emulator precision is better than 2% for

Rotational Disruption of Dust and Ice by Radiative Torques in Protoplanetary Disks and the Implications for Observations
Authors: Tung Ngo-Duy , Hoang Thiem 
Published: September 2020

Abstract
Dust and ice mantles on dust grains play an important role in various processes in protoplanetary disks (PPDs) around a young star, including planetesimal formation, surface chemistry, and being the reservoir of water in habitable zones. In this paper, we perform two-dimensional modeling of rotational disruption of dust grains and ice mantles due to centrifugal force within suprathermally rotating grains spun-up by radiative torques for disks around T-Tauri and Herbig Ae/Be stars. We first study rotational disruption of large composite grains and find that large aggregates could be disrupted into individual nanoparticles via the RAdiative Torque Disruption (RATD) mechanism. We then study rotational desorption of ice mantles and ro-thermal desorption of molecules from the ice mantle. We find that ice mantles in the disk's warm surface layer and above can be disrupted into small icy fragments, followed by rapid evaporation of molecules. We suggest that the rotational disruption mechanism can replenish the ubiquitous presence of polycyclic aromatic hydrocarbons/nanoparticles in the hot surface layers of PPDs as observed in mid-IR emission, which are presumably destroyed by extreme ultraviolet (UV) stellar photons. We find that the water snowline is more extended in the presence of rotational desorption, which would decrease the number of comets but increase the number of asteroids formed in the solar nebula. Finally, we suggest that RATD breaking up carbonaceous grains more efficiently than it does silicates might resolve the carbon deficit problem measured on the Earth and rocky bodies.
The Information Content in Analytic Spot Models of Broadband Precision Light Curves. II. Spot Distributions and Lifetimes and Global and Differential Rotation
Authors: Basri Gibor , Shah Riya 
Published: September 2020

Abstract
With the advent of space-based precision photometry missions, the quantity and quality of starspot light curves has greatly increased. This paper presents a large number of starspot models and their resulting light curves to (1) better determine light-curve metrics and methods that convey useful physical information and (2) understand how the underlying degeneracies of the translation from physical starspot distributions to the resulting light curves obscure that information. We explore models of relatively active stars at several inclinations while varying the number of (dark) spots, random spot distributions in position and time, timescales of growth and decay, and differential rotation. We examine the behavior of absolute and differential variations of individual intensity dips and overall light curves and demonstrate how complex spot distributions and behaviors result in light curves that typically exhibit only one or two dips per rotation. Unfortunately, simplistic “one- or two-spot” or “active longitude” descriptions or modeling of light curves can often be highly misleading. We also show that short “activity cycles” can easily be simply due to random processes. It turns out to be quite difficult to disentangle the competing effects of spot lifetime and differential rotation, but under most circumstances, spot lifetime is the more influential of the two. Many of the techniques tried to date only work when spots live for many rotations. These include autocorrelation degradation for spot lifetimes and periodograms for both global and differential rotation. Differential rotation may be nearly impossible to accurately infer from light curves alone unless spots live for many rotations. The Sun and solar-type stars its age or older are unfortunately the most difficult type of case. Further work is needed to have increased confidence in light-curve inferences.

Background To evaluate the impact of baseline resistance-associated substitutions (RASs) on direct-acting antiviral (DAA) treatment response among pegylated interferon in combination with ribavirin (PR) failing patients in a real-life setting. Methods Blood samples and clinical data from 171 patients who failed PR treatment were collected. All of them received rescue DAA regimens. RAS identified in the NS3, NS5A and NS5B regions by Sanger sequencing method were compared by DAA regimen and HCV subtypes. We assessed sustained virological response at 12 weeks (SVR12) and evaluated the impact of baseline RASs on the effectiveness of DAA regimens in clinical practice. Results The overall SVR12 rates were: 89.47% (153/171), 92.1% (117/127) in patients without cirrhosis versus 81.8% (36/44) in those with cirrhosis, without significant difference (χ2=3.69, P=0.08); 87.9% in genotype (GT)1b patients ( n=116) versus 93.8% in GT2a ( n=32) versus 90.5% in GT3 ( n=21) versus 100% in GT6 ( n=2), without significant difference (χ2=1.02, P=0.84); 66.7% in asunaprevir (ASV) + daclatasvir (DCV) regimen ( n=24) versus 94.0% in sofosbuvir (SOF)-based regimen ( n=133), with significant difference (χ2=19.7, P=0.001). Our results showed that the prevalence of NS3, NS5A, NS5B RASs was 45.02%, 39.76% and 71.34%, respectively, and higher incidence of RASs in cirrhosis than without cirrhosis (81.8% versus 63.8%), with a statistically significant difference (χ2=4.92, P=0.03). In the ASV/DCV cohort ( n=24), 4 of 11 patients (36.4%) with baseline NS3/NS5A RASs achieved SVR12, whereas 12 of 13 patients (92.3%) without RASs achieved SVR12, with significant difference (χ2=8.39, P=0.008). However, this relationship was not seen in the SOF-based subgroup (94.6% versus 92.7%; χ2=0.18, P=0.7). Treatment failure with DAAs occurred in 10.53% ( n=18) of our study population, baseline NS5A substitution including L31M or Y93H ( n=13) was the most frequently detected RAS, rescue regimen with velpatasvir (VEL)/SOF + ribavirin (RBV) for 12 weeks or 24 weeks was highly effective in patients who failed previous use of NS5A inhibitors, regardless of GT or cirrhosis. Conclusions Natural RASs are common in Chinese patients failing with PR treatment. High prevalence of clinically relevant RASs (such as L31M, Y93H) supports the appropriateness of HCV resistance tests to properly guide DAA-based therapy. These findings might be used to select salvage therapies.

Abstract
Tie2-expressing monocytes/macrophages (TEMs) are a distinct subset of proangiogenic monocytes selectively recruited to tumors in breast cancer. Because of the hypoxic nature of solid tumors, we investigated if oxygen, via hypoxia-inducible transcription factors HIF-1α and HIF-2α, regulates TEM function in the hypoxic tumor microenvironment. We orthotopically implanted PyMT breast tumor cells into the mammary fat pads of syngeneic LysMcre, HIF-1αfl/fl/LysMcre, or HIF-2αfl/fl/LysMcre mice and evaluated the tumor TEM population. There was no difference in the percentage of tumor macrophages among the mouse groups. In contrast, HIF-1αfl/fl/LysMcre mice had a significantly smaller percentage of tumor TEMs compared with control and HIF-2αfl/fl/LysMcre mice. Proangiogenic TEMs in macrophage HIF-2α–deficient tumors presented significantly more CD31+ microvessel density but exacerbated hypoxia and tissue necrosis. Reduced numbers of proangiogenic TEMs in macrophage HIF-1α–deficient tumors presented significantly less microvessel density but tumor vessels that were more functional as lectin injection revealed more perfusion, and functional electron paramagnetic resonance analysis revealed more oxygen in those tumors. Macrophage HIF-1α–deficient tumors also responded significantly to chemotherapy. These data introduce a previously undescribed and counterintuitive prohypoxia role for proangiogenic TEMs in breast cancer which is, in part, suppressed by HIF-2α.

Authors: Murerwa Rebecca , Amuti Thomas , Muuthuri Nikita , Wambui Anita , Ouko Innocent , Ogeng’o Julius 
Published: September 2020

Background: The calcaneus exhibits variations in articular facets and calcaneal sulcus width. These variations influence occurrence of osteoarthritic conditions, whose prevalence is significant in our setting, and are essential during surgeries involving the foot. Despite this, local data on calcaneal facets remain scarce.
Methods: Sixty calcanei were obtained from the National Museum of Kenya. The number, type and shapes of their facets were documented and calcaneal sulcus width measured. Images were taken and collected data were represented in tables and figures.
Results: The calcanei had 1–3 articular facets. The common calcanei type noted was type 1B on the right calcaneus and 1B on the left. The least was type 4 on the right and 2C on the left. In terms of shape, types 1 and 4 calcanei had non-rounded facets while type 2 had rounded facets. The width of the sulcus calcanei was narrowest among type 1 calcanei in the right foot at 0.53 cm. On the left foot, type 2 calcanei had narrower (0.455 cm, range 0.35–0.60) calcaneal sulcus width.
Conclusion: Our findings may aid in surgeries of the foot and in providing a link between local calcaneal variations and prevalence of osteoarthritic foot conditions.

Authors: Alejo A. O. 
Published: September 2020

Sandcrete blocks comprise of water, natural sand cement. Sandcrete blocks are the building units used in the construction of wall and partitions. Diverse sizes of sandcrete blocks are used to construct free standing walls and building structure with load and non – load bearing units. This research work investigate and compared strength of sandcrete blocks produced with fine aggregate from different source in Owo local government area. The targeted areas within Owo local government are Emure, Ipele and Shagari. Sieve analysis was conducted on the samples and the result revealed that all the samples are good for sandcrete block production. Thirty six sandcrete cubes samples were mould. The mix proportion 1:6 was used. Batching by volume was adopted. Curing was done by full immersion of sandcrete and compressive strength test was carried out on each specimen at 7, 14. 21 and 28 days respectively. The percentage of fine aggregate used in this research was 100% for all samples. The results revealed that sandcrete blocks produced with fine aggregate from Ipele, Shagari and Emure gives compressive strength of 4,15N/MM2, 3.56N/MM2 and 5.48N/MM2 at 28 days respectively. Based on the result of this research work, it is recommended that Emure fine aggregate (sand) is considered as most suitable out of the samples tested for sandcrete blocks production.

Considering the recent focus of the Nigeria Government to grow and develop the nation’s economy through the solid minerals sector reform, this study has been devoted to the kinetics of a Nigerian goethite ore by hydrochloric acid leaching for improved iron and steel industries applications. This study was performed in three different phases. In the first phase, acidic leaching of iron from a goethite ore was examined and the influence of the operating variables including: HCl concentration, leaching temperature, stirring speed and particle sizes was examined experimentally. The optimum condition was found to be HCl concentration of 1.81M, temperature of 80°C, 200 rpm stirring speed and particle size 0.09 μm for iron in the range of investigated parameters. Under those conditions, the highest iron recovery was obtained to be 95.67 %. In the second phase, the dissolution kinetics of iron was evaluated by the shrinking core models. The finding reveals that diffusion through the fluid was the leaching kinetics rate controlling step of the iron. The activation energy (Ea) was found to be 14.54 kJmol-1 for iron. Equation representing the leaching kinetic of iron was achieved to be 1−2/3α - (1 − x)2/3 = 0.7272 × e−38.29/8.314×T × t. The final stage of the experiment was carried out by characterizing the leached residues by X-ray diffractometer (XRD) and scanning electron microscopy (SEM), the result showed majorly the presence of rutile (TiO2), anglesite (PbSO4), and traces of iron-silicate face like pyrite (FeS), quartz (SiO2).

Optimizing the control and automation of variable torque on 3-phase induction motor using programable neuro logic controller and variable frequency drive
Authors: Eneh J.N. , Ene P.C. 
Published: September 2020

This paper presents optimizing the control and automation of variable torque on 3-phase induction motor using programmable neuro logic controller (PNLC) and variable frequency drive (VFD). The system was designed by developing a transfer model of the nonlinear input current from the load cells and feed to an improved PLC model for an approximate current function which is identified by the VFD with respect to the controlled load torque to power the 4.07KW rated 3-phase induction motor. The models were implemented using control system toolbox, neural network toolbox and simulated with Simulink in MATLAB. From the simulation of the improved controller model, the step response time performance of the PLC was improved from 2.25s to 1.22s with the PNLC.The simulation result of the VFD controlled 3-PIM motor shows that 37.07% of energy (power) was conserved compared to a characterized system with 20% energy conservation rate.
