Konsep Altruisme dalam Perspektif Ajaran Agama Islam (ITSAR)
Authors: Hidayati Fina
Published: April 2019

Permasalahan moral yang tumbuh dalam pribadi manusia adanya tarikan permanen antara upaya pemenuhan kepentingan diri pribadi (egoistic) dengan tuntutan untuk kesediaan dirinya memerhatikan kepentingan orang lain (altruistic). Moral altruism memiliki sandaran kuat dari doktrin semua agama, terutama agama Islam. Dalam Islam juga mengenal istilah al-itsar (at-tafdhil) suatu konsep perilaku sosial yang memberikan perlakuan kepada orang lain seperti perlakuan kepada dirinya sendiri. Banyaknya kajian Islam yang menjelaskan tentang pemikiran khoirunnas anfauhum linnas, maka penulis tertarik dengan penelitian yang berjudul tentang konsep altruisme dalam perspektif ajaran agama Islam yang biasa disebut dengan itsar. Metode penelitian yang digunakan adalah kualitatif dengan Pendekatan grounded theory. Hasil penelitian menunjukkan bahwa itsar adalah sikap dan tingkah laku utama yang mampu dilakukan oleh manusia yang telah mampu dan tidak hanya bersimpati dan berempati terhadap orang lain, tetapi mampu juga berkorban dan memberikan sesuatu yang bernilai bagi orang lain meskipun dirinya juga sedang memerlukan semata-mata hanya karena Allah SWT.

SCREENING THE GOTHIC: PARODY OF THE GOTHIC GENRE IN TIM BURTON’S DARK SHADOWS
Authors: Stričević Gladić Mila N.
Published: April 2019

Since the first Gothic work, Horace Walpole’s The Castle of Otranto, was published in 1764, the Gothic genre has constantly been changing and evolving. One of its main purposes has always been social criticism, and therefore Gothic literature had to change together with the society. In the 20th and especially in the 21st century with the arrival of new technologies, Gothic moved from the paper to the screen. Film and television offered a whole new range of possibilities for the postmodern authors of Gothic works to express themselves. One such artist is certainly the American director Tim Burton who is famous for his dark comedies that are almost exclusively crammed with Gothic elements. In this paper, the author shows how, in his movie Dark Shadows from 2012, Tim Burton used parody as a tool to make an on-screen pastiche of Gothic elements packed in a dark comedy for the true lovers of the Gothic genre, creating a genuine example of the postmodern Gothic.

Published: April 2019

Марија Магдалена је на културолошком плану један од најпознатијих библијских ликова. Недостатак чињеница о њеном животу омогућио је различите интерпретације њеног значаја и функције у јеванђеоским причама. Једно тумачење лика Марије Магдалене понудио је и Игњат Ђурђевић ускладивши га са временом у ком је живео и са потребама друштва које је настојао да поучи. У раду ћемо покушати да упоредимо представу Мандалијене покорнице са новозаветном и апокрифном представом ове личности.
РАБЛЕОВСКИ НИЗОВИ ЈЕЛА И ПИЋА У РОМАНУ ЈАКОВА ИГЊАТОВИЋА МИЛАН НАРАНЏИЋ
Authors: Веселиновић Сања П.
Published: April 2019

У раду се анализира функционалност раблеовских низова јела и пића у наративној структури романа српског реализма Милан Наранџић. Истражено је на који начин храна и пиће учествују у карактеризацији ликова и обликују реалистичну атмосферу дела, као и коју улогу имају у формирању слике друштва с краја 19. века и почетком 20. века. Циљ рада је утврђивање замена које се одвијају на позадинском семантичком плану дела, а које показују да се на место отровне огорчености поставља „здрав смех”, а на место лажног аскетизма весела гозба. Указује се, међутим, и на разлике које постоје између веселе гозбе код Раблеа и код Јакова Игњатовића, као и на начин на који овакве разлике доприносе скицирању лика модерног антијунака, Милана Наранџића. На основу примера из романа приказује се пишчево варирање приказа раблеовских низова и њиховог коришћења у функцији основне идеје дела. Резултати рада показују да је Јаков Игњатовић вештом инкорпорацијом гозбених слика у фабулативну структуру свог дела, допринео његовом укључивању у шири контекст српске и европске књижевности.

Published: April 2019

This study had the objective of evaluating the duration of the moulting cycle stages of Macrobrachium rosenbergii, using the method of setogenesis. The experiment was conduced in the Prawn Farming Laboratory of the Federal University in Paraiba, in the town of Bananeiras, Paraiba, Brazil. Fifteen prawns (5.7 Â± 0.3 g) were distributed in 3 aquariums (60 x 30 x 40 cm), maintained in natural photoperiod (12 x 12 hours), at a controlled temperature (28 Â°C), and feed was offered 3 times a day (8 a.m., 12 and 16 p.m.), throughout the experimental period. For identification, the animals were marked with colored silicone rings on the ocular peduncle and with colored plastic discs fixed on the carapace. From the setogenesis method, the prawns were classified into stage A, B, C, D0, D1, D2 or D3 of the moulting cycle. Setogenesis was observed stereomicroscopically every day, at the same time, 7 a.m., from the first ecdysis to the next ecdysis. The duration of the moulting cycle was 27.7 Â± 3.2 days, and the intermoult stage (C) was the longest (8.0 Â± 2.38 days). Stage A was the shortest (1 day), and the pre-moult stage (stages D) lasted 12.98+1.65 days. We concluded that juvenile of M. rosenbergii have a diecdysis type moulting cycle with shorter intermoult than pre-moult periods.

Quantitative Risk Management Improves the Success Rate of Micro-Hydraulic Fracturing Stress Tests
Authors: Bérard Thomas , Gisolf Adriaan , Desroches Jean , Gurav Hemant , Chugunov Nikita , Prioul Romain
Published: April 2019

We applied a recently introduced method to complete a feasibility assessment and design a stress testing campaign in a deep-water field in West Africa. We first reviewed the previous—and unsuccessful—campaign. Test data were inverted together with a priori knowledge from an independent geomechanical study to develop an understanding of the ambient conditions. Based on this understanding, the current campaign's chance of success (COS) was estimated to be 10%, with 1,000 psi of pressure capacity lacking to reach 95%. By analyzing the sensitivity of the risk to formation properties and design parameters, we identified various options to prevent this high, yet seemingly controllable, risk of test failure. Among them, a 1.7-ppg increase of mud density, expected to increase the COS to 80%, was deemed most effective and implemented. With 4 successful tests out of 10, the second campaign was more successful than the previous one. Yet this success rate was lower than anticipated. We inverted the second campaign's test data to revise our understanding of the in situ conditions. Our main findings are that, for this particular case, (i) the magnitude of the minimum horizontal stress was significantly higher than initially thought, (ii) the minimum horizontal stress and the horizontal stress ratio appeared to be anticorrelated, and (iii) the COS was extremely sensitive to the minimum horizontal stress. The conditions solved using the second campaign's dataset also explained the first campaign's negative outcome.

This case study demonstrates that (i) the proposed planning method enables return of experience to be captured and leveraged from one test, or one series of tests, to the next, and the design of formation stress tests to be optimized, leading to an improved success rate of formation stress tests; and (ii) the proposed inversion scheme allows insight to be gained from both successful and unsuccessful tests, including in formation conditions other than the minimum horizontal stress.
Rationale and design of influence of volatile anesthesia versus total intravenous anesthesia on chronic postsurgical pain after cardiac surgery using Initiative on Methods, Measurement, and Pain Assessment in Clinical Trials criteria assessment: study protocol for a prospective randomized controlled trial
Authors: Yu Hong , Zheng Jianqiao , Hua Yusi , Ren Shuofang , Yu Hai
Published: April 2019

Background Many patients develop chronic postsurgical pain (CPSP) after cardiac surgery, which interferes with sleep, mood and quality of life. Studies have suggested that propofol improved postoperative analgesia compared with volatile anesthetics, but the prevention effect on CPSP following cardiac surgery is still unknown. This study has been designed to compare the incidence in CPSP following cardiac surgery receiving volatile anesthesia compared to propofol-based total intravenous anesthesia (TIVA) using Initiative on Methods, Measurement, and Pain Assessment in Clinical Trials (IMMPACT) criteria assessment.
Methods This is a prospective randomized controlled trial. Five hundred adult patients undergoing cardiac surgery will be randomly allocated to the volatile or the TIVA group. The volatile group will receive sevoflurane or desflurane during surgery to provide general anesthesia. The TIVA group will receive propofol-based intravenous agents and no volatile agents during surgery. The primary outcome will be the frequency of CPSP at 3 months, 6 months and 1 year after surgery. CPSP is defined as two ways: sternal and/or thoracic pain: (1) numeric rating scale, NRS >0; (2) meets all six IMMPACT criteria for CPSP assessed using validated pain instruments.
Discussion To our knowledge, this is the first prospective randomized protocol investigating the prevention of CPSP following cardiac surgery receiving volatile anesthesia compared to propofol-based TIVA using validated pain instruments in accordance with the IMMPACT recommendations. This study will provide important information on whether the choice of these two anesthetic regimens might influence CPSP after cardiac surgery.

Validation and comparison of Diagnosis of TIA (DOT) score as a new clinical diagnostic tool for patients with a clinical diagnosis of transient ischemic attack in China
Authors: Yuan Junliang , Jia Zejin , Song Yangguang , Hu Wenli
Published: April 2019

Background: Recently, [the diagnosis of transient ischemic attack (TIA), DOT) score was considered to be a new tool for non-specialists to diagnose TIA more accurately with the sensitivity and specificity were 89% and 76%. However, the DOT score has not yet been validated externally in patients with TIA in China. Methods: We prospectively enrolled consecutive 500 patients with transient neurological symptoms, who were admitted to our hospital and underwent magnetic resonance imaging (MRI) during hospitalization between Jan 2016 and Dec 2018. Patients with transient neurological symptoms were divided into two subgroups: TIA mimic group (N=140, 28%) and definite cerebrovascular events group (including tissue-based TIA (N=252, 50.4%) and minor stroke (N=108, 21.6%)). The demographic data, clinical characteristics, laboratory findings and scores of ABCD2, ABCD3-I, Dawson and DOT were compared between the two groups. Results: A total of 500 patients with transient neurological symptoms (mean age, 61.1±12.8) were enrolled and 70% (N=350) were male. Comparing with TIA mimic groups, patients with definite cerebrovascular events group were correlated with higher diastolic blood pressure, higher proportion of motor weakness and speech abnormalities, the higher levels of uric acid and homocysteine, and the scores of ABCD2, ABCD3-I, Dawson, and DOT. The logistic regression analysis showed diastolic blood pressure (OR 1.026, CI 1.006-1.046, P=0.011), ABCD3-I (OR 1.219, CI 1.032-1.440, P=0.020) and DOT (OR 1.462, CI 1.305-1.637, P=0.001) were independently predicted the occurrence of definite cerebrovascular events. The score of DOT showed the greatest area under the ROC curve (AUC=0.728), with a sensitivity of 70.3% and specificity of 62.9%, respectively. The optimal cut point for DOT was 0.455 using the Youden Index. Conclusion: Our findings showed DOT score performed relatively good calibration and discrimination. As a novel tool of TIA, further validations are needed externally in patients with TIA with multiple centers in large samples in China.
Simultaneous cardio-cerebral embolization due to atrial fibrillation: a case report
Authors: Abe Soichiro , Tanaka Kanta , Yamagami Hiroshi , Sonoda Kazutaka , Hayashi Hiroya , Yoneda Shuichi , Toyoda Kazunori , Koga Masatoshi
Published: April 2019

Background

Simultaneous cerebral and myocardial infarction is called cardiocerebral infarction (CCI), and is rarely encountered. Because of the narrow time window and complex pathophysiology, CCI is challenging to immediately diagnose and treat.

Case presentation

A 73-year-old woman suddenly developed right hemiplegia and severe aphasia. Twelve-lead electrocardiography showed tachycardic atrial fibrillation without any significant ST-T change. Magnetic resonance imaging revealed a proximal middle cerebral artery occlusion. She was immediately treated with alteplase at the dosage approved for ischemic stroke followed by mechanical thrombectomy, and complete recanalization was achieved. Aphasia improved and she began to complain of chest pain, and reported that she had experienced chest discomfort just prior to right limb weakness. Coronary angiography showed a partial filling defect in the right coronary artery with rapid and adequate distal flow, for which percutaneous coronary intervention was not required. Alteplase was suggested to have effectively resolved the coronary emboli. The occlusions of the cerebral and coronary arteries were assumed to have occurred nearly simultaneously and cardiogenic embolism due to atrial fibrillation was considered as the most likely etiology.

Conclusions

As seen in the present case, CCI may benefit from immediate treatment with intravenous tissue plasminogen activator (IV-tPA). Although which of percutaneous coronary intervention or cerebral thrombectomy should be performed first remains unclear, we must decide to rescue the brain or heart first in each patient within a limited window of time. In this era with both IV-tPA and mechanical thrombectomy robustly established as effective intervention for acute ischemic stroke, close cooperation between stroke physicians and cardiologists is becoming more important.
Potential Phosphorus Export in Snowmelt as Influenced by Fertilizer Placement Method in the Canadian Prairies
Authors: Wiens Jordan T. , Cade‐Menun Barbara J. , Weiseth Blake , Schoenau Jeff J.
Published: April 2019

Placement strategies for P fertilizer can affect P availability to crops and influence the amounts and forms of P removed from soil in runoff, contributing to eutrophication. On the Canadian prairies, most runoff occurs during snowmelt. Two adjacent farm fields in Saskatchewan, Canada, were used to assess the effects of spring P fertilizer placement on crop P uptake, residual soil P, and potential P export in simulated snowmelt. One was in conventional tillage (CT) with no history of P fertilization, and the other was in a no‐till (NT) system with multiyear P fertilization at recommended rates. Fertilization (monoammonium phosphate) treatments were no P fertilizer (control); seed placed, deep banded, and broadcast and incorporated at 20 kg P2O5 ha−1; and broadcast treatments at 20, 40, and 80 kg P2O5 ha−1. Yield and P uptake were not affected by placement method. Water‐extractable P at the soil surface after harvest was unaffected by placement or rate at either site but increased below the 5‐cm depth at the NT site in 2016. Broadcast treatments increased P in runoff relative to in‐soil P placement for the 20‐ and 80‐kg P2O5 ha−1 treatments at the CT site and for the 80‐kg P2O5 ha−1 treatment at the NT site. Thus, in‐soil application of P fertilizer appears to be an effective strategy to reduce the risk of P export in snowmelt runoff.

Core Ideas

In‐soil fertilizer placement reduced P loss in snowmelt runoff from cropland.

Broadcasting P fertilizer increased P loss in snowmelt runoff.

Crop yield and P uptake were not affected by fertilizer placement method.

Soil P was largely unaffected by placement over the 1 or 2 yr of the study.
Metal Contamination Hotspots at Unregulated Firearm Target Shooting Sites in the Everglades
Authors: Hoch J. Matthew , Bruce Megan
Published: April 2019

Hunters and target shooters can introduce metals into the environment in the form of firearm ammunition, elevating environmental levels of these metals, which may cause plant and animal toxicity. We explored metal accumulation in the Florida Everglades at sites used for firearm target shooting that are unlicensed, unregulated, and not patrolled by law enforcement. We compared concentrations of Pb, Cu, and Al in water and soil among study sites, control sites, and a public shooting range. We also tested plants and invertebrates to identify bioaccumulation or biomagnification. Lead and Cu concentrations in the soil at the target sites were elevated (Pb mean: 11,500.1 μg g−1; Cu mean: 1558.7 μg g−1) compared with control sites (Pb mean: 35.3 μg g−1; Cu mean: 49.3 μg g−1) and were more similar to the shooting range (Pb mean: 3194.7 μg g−1; Cu mean: 567.1 μg g−1). Organisms had elevated Pb and Cu at the target sites, indicating bioaccumulation. For example, Spanish needle [Bidens alba (L.) DC] had a Pb concentration of 356.9 μg g−1 at one site but averaged 80.3 μg g−1 at the control sites. Grass shrimp (Palaemonetes paludosus) had Pb concentrations averaging 416.1 μg g−1 at target sites but only 18.9 μg g−1 at control sites. Water samples did not have elevated metal levels at the sites. Aluminum levels did not correspond to firearms use. We conclude that the illicit shooting sites are hotspots of metal pollution and pose a risk of contamination to several types of organisms. Because these sites are undocumented and unregulated, remediation may be difficult.

Core Ideas

Many firearm target shooters use locations in the wild for target practice.

Thousands of Pb and Cu bullets have been fired at wilderness sites.

High levels of Pb and Cu were found at unregulated sites used for shooting.

Unregulated firearms discharge appears to be a large source of metal pollution.

Wild target sites are unregulated, so metals accumulate without remediation.
Dietary Nutritive Value, Dung Quality, Decomposition, and Nutrient Movement into Soil in Smooth Bromegrass Pastures
Authors: Schick Bradley D. , Guretzky John A. , Schacht Walter H. , Mamo Martha
Published: April 2019

Legumes increase forage nutritive value in pastures; however, literature addressing the impacts on dietary nutritive value, dung quality, decomposition, and nutrient movement into soil remains scarce. Cattle grazing legume‐interseeded smooth bromegrass (Bromus inermis Leyss.) pastures may select diets with greater nutritive value and consequently produce dung that decomposes faster and increases nutrient movement into soil relative to cattle grazing N‐fertilized and unfertilized smooth bromegrass pastures. In 2014 and 2015, we collected rumen and dung samples from replicated experiments to evaluate effects of season (June and August), pasture type (legume‐interseeded, N‐fertilized, and unfertilized pastures), and harvest time (3, 7, and 30 d after deposition) on dietary nutritive value, dung quality, dung decomposition, and nutrient movement into soil. Cattle grazing legume‐interseeded pastures had similar dietary crude protein concentrations but 11% less dietary neutral detergent fiber concentrations than cattle grazing N‐fertilized pastures. Dung from cattle grazing legume‐interseeded pastures, meanwhile, had 5 to 12% greater N concentrations than dung from cattle grazing N‐fertilized and unfertilized pastures. From 3 to 30 d after deposition, dung C/N ratio decreased from 20.0 to 16.5; whereas, dry matter remaining diminished to 77.5%. Dung C/N ratio and dry matter remaining did not vary with season or pasture type. At Day 7, soil below dung from cattle grazing legume‐interseeded pastures had 20 and 42% greater inorganic N than soil below dung from N‐fertilized and unfertilized pastures. This research showed that pastures with legumes increases dietary nutritive value, resulting in greater dung quality and increased N movement into soil.

Acala‐type cottons (Gossypium hirsutum L.) released from New Mexico have contributed significantly to the development of commercial upland cultivars in the United States. The objective of this study was to assess the genetic gain in the breeding program between 1926 and 2000 through a combined analysis of field data on representative Acala cultivars from New Mexico and California obtained in multiple tests over years. From 1926 (‘Acala Original’) to 2000 (‘Acala 1517‐99’), the overall lint yield improvement was estimated at 3.2 kg ha−1 yr−1 but was 6.4 kg ha−1 yr−1 in 1926 to 1970 and 10.2 kg ha−1 yr−1 in 1975 to 2000. The yield improvement was accompanied by an increase in lint percentage (from 37 to 40%), fiber strength (from 270 to 300 kN m−1 kg−1), and micronaire, but with reduced boll weight. Although there was an upward trend for fiber length and uniformity and a downward trend for short fiber content, the three traits remain stable. Comparing eight New Mexico Acala 1517 cultivars with nine California Acala cultivars bred during the same period (late 1930s to the 1970s), the former, as a group, had longer and stronger fibers but slightly lower lint percentage and elongation. The Acala 1517 cotton cultivars provide an excellent source of parental lines for developing cotton cultivars with enhanced fiber quality.

Recrystallization of Al‐goethites affected mobility of heavy metals in soils.

Co‐existing Cd2+/Cr3+ decreased the Fe atom exchange rates between Fe2+aq and Al‐goethites.

Fe2+aq‐induced recrystallization of Al‐goethites stabilized Cd2+ and Cr3+.

More Cr3+ are stabilized due to its similar ionic radius with Fe3+ and Al3+.

Cd2+ ions more active than Cr3+ considering iron mineral activity in soils.

The aqueous Fe2+ (Fe2+aq)–induced recrystallization of iron minerals is an important geochemical process with critical effects on the environmental behavior of metal pollutants in soils. However, the effects of different heavy metals with distinctive physicochemical properties on the Fe2+aq–induced recrystallization of iron minerals and the different stabilization behaviors of these heavy metals remain unclear. This study examined the effects of Cd2+ and Cr3+ on the Fe2+aq–induced recrystallization of Al‐substituted goethites and the simultaneous stabilization of Cd2+/Cr3+ ions by the recrystallized Al‐substituted goethites. Results from stable Fe isotopic tracer experiments and Mössbauer characterization show that Fe atoms were exchanged between Fe2+aq and structural Fe(III) in Al‐substituted goethites with coexisting Cd2+/Cr3+, although both Cd2+ and Cr3+ decreased the exchange rates. During the Fe atom exchange, Al‐substituted goethites were recrystallized and a portion of Cd2+/Cr3+ ions were stabilized by the resulting goethite products. Compared with Cd2+, more Cr3+ ions were immobilized by the recrystallized Al‐substituted goethites due to the lower hydrolysis constant of Cr3+ than Cd2+, as well as the closer ionic radius of Cr3+ with Fe3+ and Al3+. Al‐goethites with higher Al contents further decreased the Fe atom exchange rates while increasing the amounts of immobilized metal ions when in the presence of Cd2+ or Cr3+. The findings of the present study suggest that the physicochemical properties of metal ions play critical roles in affecting their environmental behavior and fates during Fe2+aq–induced recrystallization of iron minerals in soils.

Core Ideas

The proposed laser profile meter is simple yet offers good accuracy and precision.

Data obtained by the profile meter compared well with those obtained by lidar.

Profile meter provides a practical alternative to more expensive or operationally complex systems.

An automated profile meter with vertical precision of ±0.2 mm was built to measure soil surface elevations. It consists of a laser distance meter mounted on an automated linear motion system. Operation and data logging is conducted wirelessly using a Bluetooth enabled mobile device. The profile meter performed well under various lighting conditions and on a variety of natural materials, with the exception of specular surfaces. It is inexpensive (<$1500), consists of readily available components, portable, and easy to setup in the field (<10 min). When measuring soil random roughness the profile meter was compared with a ground based terrestrial Light detection and ranging (lidar). The lidar systematically overestimated random roughness by approximately 15% compared with the profile meter.

When afraction of scavenger petroleum reserves is steadily growing the use of methods for oil recovery increasing and intensifying of oil fields development plays a decisive role in maintaining the level of oil production. One of the methods used to increase oil recovery by isolating water inflows is the injection of a surfactant composition on a hydrocarbon base, SNPCH-9633 reagent. The action of the reagent is based on the formation in washed zones of of highly viscous gel-like W/O emulsions due to the crushing of aqueous phasedroplets. Thus W/O emulsion generated in the pore space of the formationblocks the water-saturated interlayers which leads to a reduction in water cut of the produced well production by 10-30% depending on the application conditions. The method is selective technological and easy to implement. The reagent SNPCH-9633 has a low viscosity and does not change its properties when stored over a wide temperature range for a long time. In this work using the visualization methods the features of emulsion generation during water and reagent movement in a porous structure, the manifestation of the dynamic blocking phenomenon and the rheological properties of emulsions in a wide range of aqueous phase concentrations are studied.

Nosocomial infections are one of the major causes of morbidity in the Neonatal Intensive Care Unit (NICU). Known risk factors include birth weight, gestational age, severity of illness and its related length of stay, and instrumentation.

Objective:

The purpose of this article is to determine the occurrence of Nosocomial Infections (NIs), including infection rates, main infection sites, and common microorganisms.

Methods:

A retrospective study was conducted between June 2015 and December 2016.

Results:

The incidence of nosocomial infection was 16%. The primary reasons for admission were intauterin growth retardation (52.5%). Klebsiella Pneumoniae was the most commonly identified agent in the blood cultures and in the hospital unit (43.6%). The mortality rate from nosocomial infection was 52.6%. The proportion of infected newborns with a lower than normal birth weight was predominant (58.13%).

Conclusion:

Thus, prevention of bacterial infection is crucial in these settings of unique patients. In this view, improving neonatal management is a key step, and this includes promotion of breast-feeding and hygiene measures.

Authors: HemRaj Vashist , Gupta Avneet , Upmanyu Neeraj
Published: April 2019

Aim:

The study aimed to evaluate the anti-arthritic potential of ethanolic extract of Cissampelos pareira (Menispermaceae) and Stephania glabra (Menispermaceae).

Methods:

Sprague Dawley rats (200 ± 20g) were used as experimental animals. Animal models like Freund’s Adjuvant (FA) induced inflammation, Monosodium Iodo Acetate (MIA) induced osteoarthritis and Potassium Oxonate Induced Uricemia (POU) were used for the study. Total Leukocyte Count (TLC) and Differential Leukocyte Count (DLC) and Tumor Necrosis Factor (TNF-α) were assessed in the blood of rats. The dose of 200 mg/kg of the ethanolic extract of Cissampelos pareira (CPE) and Stephania glabra (SGE) was recorded as the safe dose.

Results:

CPE and SGE significantly decreased (P < 0.001) elevated paw edema on day 7, 14, 21 and 28 in FA-induced arthritis as compared to the control group. Both extracts were found to cause a significant decrease. Also, a significant decrease (P < 0.001) in MIA-induced increase in knee diameter was observed in extracts treated groups. CPE was found to be more effective than SGE. Both extracts were found to be significantly effective (P < 0.001) in potassium Oxonate induced hyperuricemia.

Conclusion:

From the result, it is clear that the ethanolic extracts of CPE and SGE possess beneficial effects against rheumatic disease, osteoarthritis as well as against hyperuricemia. The result may provide an effective treatment against such arthritic problems. Again it may be assumed from the study that the drugs Cissampelos pareira and Stephania glabra can be used to formulate novel drug formulations against the above said ailments.
Data Detection in Single User Massive MIMO Using Re-Transmissions
Authors: Vasudevan K. , Madhu K. , Singh Shivani
Published: April 2019

Background:

Single user Massive Multiple Input Multiple Output (MIMO) can be used to increase the spectral efficiency since the data is transmitted simultaneously from a large number of antennas located at both the base station and mobile. It is feasible to have a large number of antennas in the mobile, in the millimeter wave frequencies. However, the major drawback of single user massive MIMO is the high complexity of data recovery at the receiver.

Methods:

In this work, we propose a low complexity method of data detection with the help of re-transmissions. A turbo code is used to improve the Bit-Error-Rate (BER).

Results and Conclusion:

Simulation results indicate a significant improvement in BER with just two re-transmissions as compared to the single transmission case. We also show that the minimum average SNR per bit required for error-free propagation over a massive MIMO channel with re-transmissions is identical to that of the Additive White Gaussian Noise (AWGN) channel, which is equal to -1.6 dB.
