Published: July 2019

The birth of the first sharia bank in Indonesia is PT Bank Muamalat Indonesia (BMI). However, lately many emerging sharia-based financial institutions other, cultivated sharia cooperative in the form of BMT. Inside the BMT, we are familiar with the term buy back or bai' al-wafa'. Bai 'al-wafa' is a buying and selling is done by someone who need money by selling (real estate/real property) goods is owned by agreement if he can pay (the price) then he can take back the goods while the legal basis bai 'al-wafa' according to Hanafi Madzhab is istihsan. Istihsan is the turning of a mujtahid from qiyas street jaly (real) to qiyas the khafi (vague) or the turning of a mujtahid from law kulli (general) to the law istitsna`i (limit) because it crossed their minds there is a superior proposition.

La travesía de Eleodoro Vargas Vicuña y João Guimarães Rosa
Authors: Vilcapuma Vinces Patricia Bernarda 
Published: July 2019

La autora del texto afirmará que el proyecto escritural de João Guimarães Rosa y Eleodoro Vargas Vicuña ha logrado trascender y traspasar aquella postura de pertenencia a espacios determinados. Asimismo, sus narrativas, que logran la elevación estética del lenguaje en pos del rescate de la esencia popular y una comunión con la naturaleza, demuestran que la exigencia de una respuesta última y la reflexión sobre la existencia humana están presentes indistintamente de tiempos y espacios geográficos. Se verá, así, que su narrativa es más que el representar el modo de hablar de un pueblo, es un reconocimiento de lo que el ser humano necesita, que es algo más profundo —y que no está en él mismo—, que exige compromiso, fuerza y coraje.

Abstract The research aimed to study the potential of fish culture in floating net and its development at Tandengan Village Minahasa Regency. This research was a case study and the data collected was analyzed qualitatively with a simple mathematical calculations. Observation and interview to the fishermen who had floating net culture were used to gather the primary and secondary data. The results showed that education degree of fish culturist was 20% elementary school, 20% intermediate school, 60% high school, and 10% bachelor. People experience in running fish culture activity was over 10 years in average. Fish culture activities increased year by year. The problems faced by fish culturist included weather, water condition, food price, and market demand. The increase of floating net culture activities in this area had resulted in the increase of labor demand. The skill of fish culturist needed to be develop through education and training as well as through establishing fish culturists cooperation considering there were many fish culturists present at Tandengan village. This was important due to the development of floating net culture had positive impact in providing working opportunity and increasing people welfare.

Penggunaan ragi roti (Saccharomyces cereviciae) secara in situ untuk meningkatkan respon kebal non-spesifik ikan nila (Oreochromis niloticus)
Authors: Rawung Meilina E , Manoppo Henky 
Published: July 2019

The objetive of research was to examine the effect of yeast cell Saccharomyces cereviciae on non-specific immune response of nile tilapia, Oreochromis niloticus. Juveniles weighing 31.83 g in average were cultured in five concrete tanks with a density of 30 fish per tank. The fish were fed pellet supplemented with yeast cell at five different doses (0, 10, 20, 30, 40 g/kg pellet) for three consecutive weeks as much as 4%/bb/day, twice daily. At the end of feeding, three fish from each tank were sampled to measure the immune parameters namely total leucocyte count and phagocytosis activity of phagocyte cells. Research results showed that after three weeks of feeding, total leucocyte and phagocytosis activity of fish fed pellet supplemented with yeast cells were significantly different as compared to those of control fish. The highest total leucocyte and phagocytosis activity were achieved in fish fed pellet supplemented with 10 g of yeast cells/kg pellet. It was concluded that the use of yeast cells for three weeks could enhance the nonspecific immune response of nile tilapia. Keywords: Saccharomyces cerreviciae, nonspecific immune response, total leucocyte count, phagocytosis activity, nile tilapia, Oreochromis niloticus

Mass-loss Rates for O and Early B Stars Powering Bow Shock Nebulae: Evidence for Bistability Behavior
Authors: Kobulnicky Henry A. , Chick William T. , Povich Matthew S. 
Published: July 2019

Abstract
Second only to initial mass, the rate of wind-driven mass loss determines the final mass of a massive star and the nature of its remnant. Motivated by the need to reconcile observational values and theory, we use a recently vetted technique to analyze the mass-loss rates in a sample of OB stars that generate bow shock nebulae. We measure peculiar velocities from new Gaia parallax and proper motion data and their spectral types from new optical and infrared spectroscopy. For our sample of 70 central stars in morphologically selected bow shock nebulae, 67 are OB stars. The median peculiar velocity is 11 km s−1, significantly smaller than classical “runaway star” velocities. Mass-loss rates for these O and early B stars agree with recently lowered theoretical predictions, ranging from ≃10−7
M
⊙ yr−1 for mid-O dwarfs to 10−9
M
⊙ yr−1 for late O dwarfs—a factor of about 2.7 lower than the often-used Vink et al. formulation. Our results provide the first observational mass-loss rates for B0–B3 dwarfs and giants—10−9 to 10−8
M
⊙ yr−1. We find evidence for an increase in the mass-loss rates below a critical effective temperature, consistent with predictions of the bistability phenomenon in the range T
eff = 19,000–27,000 K. The sample exhibits a correlation between modified wind momentum and luminosity, consistent in slope but lower by 0.43 dex in magnitude compared to canonical wind–luminosity relations. We identify a small subset of objects deviating most significantly from theoretical expectations as probable radiation-driven bow wave nebulae by virtue of their low stellar-to-nebular luminosity ratios. For these, the inferred mass-loss rates must be regarded as upper limits.
Orbital Stability and Precession Effects in the Kepler-89 System
Authors: Kane Stephen R. 
Published: July 2019

Abstract
Among the numerous discoveries resulting from the Kepler mission are a plethora of compact planetary systems that provide deep insights into planet formation theories. The architecture of such compact systems also produces unique opportunities to study orbital dynamics in compact environments and the subsequent evolution of orbital parameters. One of the compact Kepler systems is Kepler-89, a system for which the radial velocity follow-up observations place strong upper limits on the masses of the planets and their Keplerian orbital elements. The potential for noncircular orbits in this system make it a compelling system to study dynamical constraints on the measured orbital parameters. I present a dynamical analysis of the system that demonstrates the stability of the circular model and shows that the eccentric model of the system is not stable. The analysis indicates that planets c and d, although close to the 2:1 secular resonance, do not permanently occupy the 2:1 resonance configuration. I explore regions of orbital parameter space to identify the upper bounds of orbital eccentricity for the planets. I further show how the dynamics in the compact system leads to significant periastron precession of the innermost planets. Finally, I quantify the effect of the periastron precession on the transit times of the planets compared with the cyclic variations expected from transit timing variations.
Risk Factors for Poor Surgical Outcome of Pediatric Nasolacrimal Duct Obstruction
Authors: Dietze Jamie , Suh Donny 
Published: July 2019

Purpose:
To determine whether there are common factors that may help predict if a child is at a higher risk for surgical failure for nasolacrimal duct obstruction.

Methods:
This retrospective, observational case-control clinical study reviewed patient factors present prior to surgical intervention and their correlation with the necessity of multiple surgeries. A pediatric ophthalmologist identified patients who required surgical correction based on symptom history refractory to conservative management. Patients were grouped by the need for multiple surgical interventions versus single surgery. Patient factors hypothesized to predispose patients to an unsuccessful initial procedure were compared via odds ratio analysis. Patient success was based on symptom resolution 6 months postoperatively.

Results:
Patient factors with statistically significant increased odds ratios were trisomy 21, allergic rhinitis/seasonal allergies, history of an upper respiratory tract infection within 1 month, and obstructive sleep apnea.

Conclusions:
This study suggests that patients with trisomy 21 or a history of recent upper respiratory tract infection may be correlated with a higher risk of failure with a probing and irrigation surgery only. Patients with trisomy 21 may benefit from an initial balloon dilation procedure rather than probing and irrigation, due to an increased risk profile. Patients with a recent upper respiratory tract infection may benefit from postponing surgery until symptom treatment or resolution.

Surgical Responses and Outcomes of Bilateral Medial Rectus Recession in Esotropia With Spinocerebellar Ataxia
Authors: Chun Bo Young , Freire Marcelle V. , Cestari Dean M. 
Published: July 2019

Purpose:
To evaluate the surgical responses and outcomes of bilateral medial rectus (BMR) recession in esotropic patients with spinocerebellar ataxia (SCA) and to compare the results with normal controls.

Methods:
The medical records of patients with SCA who underwent strabismus surgery for esotropia between 2006 and 2015 were reviewed retrospectively. Five esotropic patients with SCA (SCA group) and 10 esotropic patients without neurologic disorders (control group) who underwent BMR recession were included. Success rates, surgical responses, and the amount of preoperative and postoperative distance-near disparity were evaluated and compared between the groups.

Results:

The mean preoperative esodeviation was not different between the SCA and control groups (20 vs 17.3 prism diopters [PD],
P
= .214). However, patients with SCA showed significant undercorrection compared with controls 1 week postoperatively (4.8 vs 1.0 PD,
P
= .048) and at the final follow-up (6.8 vs 1.8 PD,
P
= .032). The surgical success rates for the SCA and control groups were 40% and 80%, respectively (
P
= .095). Patients with SCA demonstrated a significantly reduced surgical response compared with controls (3.15 vs 3.87 PD/mm,
P
= .004), and a greater amount of postoperative distance-near disparity than controls (8.0 vs 1.1 PD,
P
= .001).

Conclusions:
A significant undercorrection was observed following BMR recession in esotropic patients with SCA. Accordingly, the authors recommend a slight overcorrection of 5 to 10 PD or adding a slanting procedure when planning strabismus surgery for this distinct group of patients.

Effect of Live Mulch Conservation Practices on Crop Yields: A Study of Sweet Potato in Southwest Nigeria
Authors: Oshunsanya S. O. , Okoh G. E. , Amao P. A. , Aliku O. , Chukwuma E. A. 
Published: July 2019

Live mulch can reduce land degradation by protecting the surface soil from direct impacts of rain drops and consequently increasing crop yields. To compare the potential biomass production of sweet potato for soil conservation, two farmlands with different degradation potentials were selected to plant ten commonly grown cultivars of sweet potato of Africa. Soil degradation rate (SDR) and vulnerability potential (Vp) of the two farms were also compared using selected soil properties as assessment tools. Results indicated that Farm A with higher total biomass slightly degraded with low vulnerability potential (SDR/Vp ≈ 2/4) while the Farm B with lower biomass severely degraded with high vulnerability potential (SDR/Vp ≈ 4/2). Correlation between biomass and yields was not significant for both the farms, indicating that biomass alone cannot determine the yields of sweet potato. On a slightly degraded soil, Benue, Akinima, TIS 87/0087 and Arrow tip cultivars had the highest tuber production (100 - 70)%, followed by Ex-Igbaraiam, Eruwa, Shaba, Ishiayi and TIS 8441 (69 - 50)% and least by Akwide (<50%). While on a severely degraded soil, Ex-Igbaraiam cultivar had the highest yield production (100 - 70) %, followed by Shaba, TIS 87/0087, Benue and TIS 8441 (69 - 50)% and least by Akwide, Eruwa, Ishiayi, Akinima and Arrow tip (<50%). The trend of the result reflects the ability of potato cultivars to cope with degraded soils. In terms of biomass production, TIS 87/0087, Ex-Igbaraiam, TIS 8441 and Benue were highest followed by Shaba and Akwide and least by Arrow-tip and Ishiayi. The results indicates that TIS 87/0087 cultivar can perform well under severely degraded soil while Ex-Igbaraiam and TIS 8441 with high biomass potential are better used as folders especially on a degraded soil.

Background and Objectives: The developments of fourier transform infrared (FT-IR) spectroscopic instrumentation, and application, over the years has made it a powerful analytical tool in the study of oils and fats. This work has explored fourier transform Infra-Red for characterization of plant oils from selected cultivars grown in Nigeria. The selection of these plants oils that flourishes in Nigeria aside their used primarily for nutritional applications, is dependent on the fatty acid (FA) composition of triacylglycerol (TAG which make them potential for bioenergy and biofiuel production considering the explosion of energy demand through alternative energy sources. They are also needed for the preparations of chemical feedstocks, biopolymer and composites, skin care products. Oils from these plants can provide renewable sources of high-value fatty acids for both the chemical and health-related industries. We report here several areas where these plant oils can have a significant impact on the emerging bioeconomy.
Materials and Methods: The samples were each placed in contact with KBr disc and FT-IR spectra were collected in frequency 4500-400 cm-1 by coadding 32 scans and at resolution of 4 cm-1. All spectra were rationed against a background spectrum. In each scan, a new reference background spectrum was detected.
Results: The spectra of oils of the present investigation revealed the following bands 1522, 1449.55, 1364.68, 1444.73, 1364.68, 1445.09, 1369.50, 1447.62, 1362.75, 1449.55, 1371.43, 1447.62, 1366.54, 1447.62, 1450.5, 1360.82, 1370.47, 1446.66, 1246.06, 1364.47, 1448.59 for Adansonia digitata, Ricinus communis, Sesamum indicum, Jatropha curcas, Allium cepa, Cucumis melo, Lannea microcarpa, Lagenaria vulgaris and Sesamun indicum seed oil respectively. 1450 cm-1- 1444 is related to bending vibration of CH2, and CH3; (cis =C–H bending) and at 1360 - 1370 cm-1 is concerned with the bending vibrations CH2 groups which showed total unsaturation. The results obtained shows that all the oils are unsaturated because there is no band around 3005- 3009 which is the band that normally determine the index of degree of unsaturation.
Conclusion: The FT- IR spectroscopy proved to be an important technique for identification, analysis, determination of degree of saturation of fatty acids in oils suitable for industrial applications.

Cancer a leading cause of human mortality worldwide is characterised by the unseemly growth of cellular mass and signalled through the enlargement of stress. Management of cancer treatment is still buried and has been recently alerting the need to discover a drug molecule with lesser side effects. The objective of the present study is to explore the anticancer activity and docking studies of 1-(5-substituted phenyl) isoxazol-3-yl)-5-phenyl-1H-tetrazole derivatives. The compounds were evaluated for in-vitro anticancer activity under the drug discovery program of National Cancer Institute (NCI), USA. Only seven compounds were selected and screened for anticancer activity at a single high dose (10-5 M) using NCI 60 cancer cell lines. Among all the selected compounds, 4b and 4i exhibited significant anticancer activity against Leukemia cell lines. Molecular docking studies for the 5-phenyl-1-(5-substituted phenylisoxazol-3-yl)-1H-tetrazole analogues was done by Schrodinger software. Docking results stated that the compounds 4b and 4i has good dock score among the other derivatives which shows good binding efficiency towards receptor.

Foot-and-mouth disease (FMD) is an economically important viral disease of domestic animals and wildlife. High circulation occurs during outbreaks but little is known about the current transmission dynamics in sedentary cattle and sheep herds. To investigate on this, samples from cattle and sheep located in the Vina Division of the Adamawa region of Cameroon, during FMD outbreaks were collected. Non-Structural Protein (NSP) and antigen detecting/serotyping FMD ELISAs were used for sample screening. The NSP serological data of cattle was used to estimate transmission parameters in catalytic and reverse catalytic models. The Akaike’s Information Criteria (AIC) revealed the reverse catalytic model as the most parsimonious for the NSP serological data and was used to estimate the force of infection (FOI), the rate of waning immunity and to estimate historic periods of sustained transmission. Four serological types of FMD notably O, A, SAT 1 and SAT 2 were identified from cattle vesicular epithelia tissues. Seroprevalence findings revealed 65.14% and 15.71% FMDV antibodies in cattle and sheep respectively with highest prevalence in both populations occurring in Mbidjoro. The FOI (λ) in sedentary herds was constant; the rate of waning immunity (ω) was 0.32 meaning cattle are generally immune for 3.12 years post natural infection. The reproductive number (Rt) was 7.33, meaning approximately 87% of cattle always need to be effectively immunized to prevent outbreaks. Therefore, FMD circulates in sedentary cattle and sheep populations in the study area with four serological types detected in cattle.
