Udang mantis jenis Harpiosquilla raphidea merupakan salah satu jenis krustase hasil tangkapan bernilai ekonomi pada beberapa daerah pesisir di Indonesia. Namun komposisi biokimia jenis ini belum banyak diketahui. Oleh karena itu, tujuan penelitian ini adalah untuk memepelajari secara kuantitatif unsure-unsur penting yang terkandung dalam daging udang mantis yang berasal dari perairan Kuala Tungkal, Jambi dan Cirebon. Hasil penelitian memperlihatkan bahwa rendemen udang mantis dari kedua lokasi tidak berbeda nyata. Selain itu, udang dari kedua lokasi juga tidak memperlihatkan kandungan mikro mineral (seng, besi dan tembaga) yang berbeda. Namun demikian, udang mantis Kuala Tungkal, Jambi memiliki kandungan natrium, kalium dan kalsium lebih tinggi dibandingkan udang mantis Cirebon. Tetapi, udang mantis Cirebon kandungan magnesiumnya lebih baik. Pemasakan dengan media asam dan dengan proses perebusan akan menghasilkan tingkat kelarutan mineral tertinggi. Kata kunci: Udang mantis, Harpiosquilla raphidea, komposisi biokimia, kelarutan mineralThe mantis shrimp, Harpiosquilla raphidea, is a valued crustacean species captured mainly in some Indonesian coastal waters. Yet, the biochemical composition of this species is still inadequately understood. For that reason, the aim of this study was to quantify the content of essential elements of specimens from the Kuala Tungkal, Jambi and Cirebon Coast. The meat yield of the shrimps collected from the two locations are not significantly different. In terms of proximate chemical composition, all chemical characters of the shrimps from Kuala Tungkal, Jambi and Cirebon are not significantly different, except the fat content. As far as the mineral composition is concerned, no differences were observed between either two locations for micro minerals (zinc, iron and copper). However, the shrimps of Kuala Tungkal, Jambi coast showed higher sodium, potassium and calcium contents than those of Cirebon coast. Yet, for magnesium the shrimp of Cirebon had higher content in comparison with that of Kuala Tungkal, Jambi. Media acid with boiling process would bring about the highest solubility of minerals. Key words: Mantis shrimp, Harpiosquilla raphidea, biochemical composition, mineral solubility
Separation Performance of Nanostructured Ceramic Membranes: Analytical Model Development
Authors: Rezakazemi Mashallah , Shirazian Saeed 
Published: June 2018

AbstractNanostructured ceramic membranes have shown considerable separation performance. In this work, an analytical model is developed to evaluate the separation performance of porous ceramic membranes in gas separation applications. The model takes into account three layers, i. e., (1) active layer, (2) interlayer, and (3) support layer. For estimation of sorption at the interface of feed stream and membrane, the partition coefficient model was used and the unsteady-state conservation of mass equation coupled to molecular models of the diffusivity coefficient was used to predict the permeation of penetrant hydrogen gas through a ceramic membrane. It was observed that the model can be readily applied to other systems of interest as a predictive tool.

Published: June 2018

Abstract

Background
Some pediatric endocrinologists recommend that girls with central precocious puberty (CPP) have cranial magnetic resonance imaging (MRI) performed only if they are younger than 6 years of age. However, no practice guidelines exist. The objective of this review was to assess the frequency of intracranial lesions in girls with CPP.

Content
We searched six electronic databases (PubMed, Cochrane, Web of Science, SCOPUS, ProQuest, and Dissertation & Theses) from 1990 through December 2015. We included studies on girls with CPP and MRI data. Case reports, case series, studies from the same author/group with the same patient population, and studies with conditions predisposing to CPP were excluded. Two physicians independently reviewed the search results and extracted data. A random-effects model was used to obtain pooled prevalence of positive MRI’s across studies. Heterogeneity among studies was evaluated with the Q-statistic. Publication bias was assessed with funnel plots and Egger’s test. Pooled prevalence was computed by age group. A linear regression assessed the relationship between intracranial lesion prevalence and healthcare availability. We included 15 studies with a total of 1853 girls <8 year old evaluated for CPP.

Summary
The pooled prevalence from all studies was 0.09 [95% confidence interval (CI) 0.06–0.12]. There was a significant heterogeneity, indicating the appropriateness of a random effects model in computing pooled prevalence. In the few studies stratified by age group, pooled prevalence was 25% in girls <6 years vs. 3% in girls 6–8 of age.

Outlook
Our results support that the benefit of routine MRIs in girls with CPP older than 6 years of age without any neurological concerns is not clear-cut.
The grammaticalization of object pronouns: Why differential object indexing is an attractor state
Authors: Haig Geoffrey 
Published: June 2018

AbstractWhile the grammaticalization of person agreement is a widely-cited and apparently uncontroversial topos of grammaticalization theory, the striking differences in the outcome of subject pronoun, and object pronoun grammaticalization, remain unexplained, and the relevant literature continues to assume a unified grammaticalization pathway. This paper argues that the grammaticalization of object pronouns is fundamentally different to that of subject pronouns. More specifically, although object pronouns may be rapid early grammaticalizers, often losing prosodic independence and cliticizing to a verbal head, they do not advance further to reach the stage of obligatory agreement markers typical of subject agreement. Typically, object markers remain at the stage of Differential Object Indexing, where their realization is conditioned by a bundle of semantic and pragmatic factors exhibiting close parallels to those operative in Differential Object Marking. Evidence from language typology, and from the diachrony of person markers across two millennia of Iranian languages, is adduced to back up these claims. Thus the widely-assumed grammaticalization cline for the grammaticalization of agreement needs to be reconsidered; for object agreement, there is evidently an attractor state, that of Differential Object Indexing, beyond which object agreement seldom proceeds. Finally, explanations grounded in discourse data are proposed, which also account for why obligatory object agreement in the category of person is so rare, while gender and number agreement for objects is far less constrained.

Abstract

Laurus nobilis leaves contain flavored and bioactive components with relevant biological properties for human health that are attributed to an abundant presence of highly bioactive secondary metabolites. However, the separation process for these bioactive molecules from plant matrix is seriously limited by the presence of a physical barrier (cell wall). Thus, the use of novel extraction procedures to enhance their release is particularly important. In this work, the potential use of microwave-assisted extraction (MAE) as a tool to improve the extraction efficiency of bioactive compounds from bay leaves and their characterization was evaluated. The effects of irradiation time (3, 6 and 9 min) and aqueous ethanol concentration (0, 25 and 50%) on the extraction of phenolic compounds were evaluated. A response surface methodology was applied to determine the best extraction conditions by MAE. The maximum total phenolic compound under the best conditions (9 min time irradiation and aqueous ethanol 50%) was 10.63±0.91 mg gallic acid equivalent/g plant using MAE. Also, the antioxidant potential of the extracts obtained was evaluated.

Abstract
Richman, ED, Tyo, BM, and Nicks, CR. Combined effects of self-myofascial release and dynamic stretching on range of motion, jump, sprint, and agility performance. J Strength Cond Res 33(7): 1795–1803, 2019—Massage has been used as both a pre- and post-exercise modality with purported benefits to flexibility and athletic performance. This study was designed to determine the effect of a 6-minute protocol of self massage known as self-myofascial release (SMR) using a foam rolling device in conjunction with a general warm-up and sport-specific dynamic stretching (DS) session on flexibility and explosive athletic performance in a sample of 14 female collegiate athletes. After familiarization, participants completed 2 testing sessions that began with 5 minutes of jogging at a self-selected pace, followed by either a 6-minute foam rolling session (SMR) or 6 minutes of light walking (LW) and a subsequent 6-minute period of sport-specific DS. Sit-and-reach (SR) was measured after a general warm-up, the SMR, or LW session, and following DS, after which participants performed 3 trials each of squat jump (SJ), countermovement jump (CMJ), and drop jump (DJ). Two additional tests, the agility T-Test (TT) and a 10-yd short sprint (SP), were then performed. The change in SR after SMR was significantly greater than the change seen in SR after LW, although the total changes seen in each condition were not statistically different after the addition of DS. Squat jump and CMJ improved by 1.72 ± 2.47 cm and 2.63 ± 3.74 cm (p = 0.070, p = 0.070), with no significant change to DJ, SP, and TT. Self-myofascial release in the form of foam rolling after a general warm-up and preceding a DS session seems to improve SJ and CMJ with no detriment to flexibility, DJ, sprint, and agility performance in comparison with LW and DS.

Abstract
Cuenca-Fernández, F, Ruiz-Teba, A, López-Contreras, G, and Arellano, R. Effects of 2 types of activation protocols based on postactivation potentiation on 50-m freestyle performance. J Strength Cond Res 34(11): 3284–3292, 2020—Postactivation potentiation (PAP) is a phenomenon which improves muscle contractility, strength, and speed in sporting performances through previously applied maximal or submaximal loads on the muscle system. This study aimed to assess the effects of 2 types of activation protocols based on PAP, on sprint swimming performance. A repeated-measures design was used to compare 3 different scenarios before a 50-m race. First, all of the participants performed a standard warm-up (SWU), consisting of a 400-m swim followed by dynamic stretching. This protocol acted as the control. Subsequently, the swimmers were randomly assigned into 2 groups: the swimmers in the first group performed the SWU followed by a PAP one-repetition maximum warm-up (RMWU), consisting of 3 “lunge” and 3 “arm stroke” repetitions, both at 85% of the one-repetition maximum. The swimmers in the second group performed the SWU followed by a PAP eccentric flywheel warm-up (EWU), consisting of one set of 4 repetitions of exercises of both the lower and upper limbs on an adapted eccentric flywheel at the maximal voluntary contraction. The time required for the swimmers to swim 5 and 10 m was shorter with the PAP protocols. The swimming velocity of the swimmers who underwent the EWU and RMWU protocols was faster at 5 and 10 m. The best total swimming time was not influenced by any of the protocols. When isolating swimming (excluding start performance and turn), best time was achieved with the SWU and RMWU compared with EWU (SWU: 20.86 ± 0.95 seconds; EWU: 21.25 ± 1.12 seconds; RMWU: 20.97 ± 1.22 seconds). In conclusion, a warm-up based on PAP protocols might exert an influence on performance in the first meters of a 50-m race. Nevertheless, other factors, such as fatigue, could modify swimming patterns and yield results contradictory to those of the desired task.

Abstract
Rabbani, A, Kargarfard, M, and Twist, C. Fitness monitoring in elite soccer players; group vs. individual analyses. J Strength Cond Res 34(11): 3250–3257, 2020—The aims of this study were to (a) examine changes in group and individual HR measures during a submaximal warm-up test, and (b) investigate the relationship between accumulated internal training loads and HR changes during an in-season phase among elite soccer players (n = 14). Before and after an in-season phase (24 days), exercise HR (HRex) and HR recovery (HRR) expressed either as the number of beats recovered (HRR60s) or as the mean HR (HRpost1) during 1 minute of recovery were analyzed. Heart rate measures were expressed as the % of maximal HR. Session rating of perceived exertion (sRPE) was computed for all training/match sessions. Group and individual HR changes were analyzed using magnitude-based inferences. Pearson correlation coefficients were also used to examine the relationships. Group analyses of HR changes revealed there were possibly to likely trivial changes in all HR measures. When analyzing individual data, no substantial change was observed for HRR60s%. However, substantial changes in HRex% and HRpost1% were observed for 4/14 and 5/14 players, respectively. The relationships between HRex% and HRpost1% were nearly perfect (r = 0.90, confidence limits [0.82–0.95]). The associations between changes in HRex% and HRpost1% were also nearly perfect (r = 0.92, 0.80–0.97). A very large inverse correlation was observed between HRex% and accumulated sRPE (r = −0.75, −0.44 to −0.90). This study highlights the value of conducting individual vs. group aerobic fitness monitoring. This study also showed the importance of how HRR is reported when aerobic fitness monitoring of elite soccer players.

Published: June 2018

Introducción: El hemangiopericitoma es un tumor vascular poco frecuente en la región nasosinusal que se asocia con epistaxis y obstrucción nasal como principales síntomas. Cuando se presenta en esta región, tiene características clínicas especiales que lo hace diferente de otras localizaciones.Presentación del caso: A continuación se presenta el caso de una paciente de 43 años de edad, con síntomas de obstrucción en fosa nasal derecha y 6 meses de evolución asociados con rinorrea mucopurulenta y epistaxis recurrente del lado derecho. El examen físico mostró una masa obstructiva en el lado derecho con origen en la placa cribriforme. Una tomografía computarizada de los senos paranasales reveló un bloqueo completo de la cavidad nasal derecha por un contenido homogéneo, con densidad de partes blandas, sin captación de contraste evidente. La lesión se extendía hacia el lado superior de la placa cribriforme, sin extensión intracraneal u orbitaria. La paciente fue tratada con cirugía endoscópica y el estudio anatomopatológico reveló un hemangiopericitoma sinonasal. La paciente tuvo remisión completa y se realizó seguimiento por 3 años sin recurrencia.Conclusión: El tratamiento recomendado para el hemangiopericitoma es la escisión quirúrgica total con márgenes libres, cuyos resultados son generalmente buenos. El riesgo de recurrencia parece estar asociado con una escisión tumoral incompleta. Se presenta una revisión de literatura, así como comentarios sobre sus características principales.

El presente artículo recoge los resultados y las reflexiones del análisis hecho a un material editorial diseñado por un centro interactivo de ciencia y tecnología, cuyo objetivo era divulgar el conocimiento científico y tecnológico sobre el gas natural.Como estrategia metodológica, se realizó un análisis de contenido usando la herramienta propuesta por Fernández et al. (2002, 2003) sobre las visiones deformadas de la ciencia, lo cual se fortaleció con un abordaje en torno al proceso de diseño del material usando la Teoría Actor-Red. Como resultado de la investigación, fue posible identificar que las deformaciones de la ciencia están íntimamente ligadas a las relaciones de poder que se configuran durante el proceso de diseño del material editorial. Paralelo a lo anterior, se identifica que el posicionamiento de los centros interactivos, como escenarios socialmente reconocidos en el campo científico y tecnológico, también tienen responsabilidades asociadas con las deformaciones de la ciencia y la tecnología en el contexto social en que actúan.
Double‐Crop Soybean Germination, Seedling Growth, and Seed Yield Differences when Preceded by Different Winter Annuals

Published: June 2018

Water soluble extract of winter annual crop stover did not affect soybean germination.
Soybean roots were largest when produced in soil from winter fallow and canola plots.
Double‐crop soybean seed yield was similar among four preceding winter annual crops.
Increasing sustainable grain and oilseed production is a significant challenge for US producers. Double‐cropping soybean [Glycine max (L). Merr.] with a winter annual crop is one option to increase grain and oilseed production while reducing nutrient and sediment losses. Anecdotal observations that winter wheat (Triticum aestivum L.) limits double‐crop soybean productivity are common, which is seemingly corroborated by documentation that winter wheat contains allelopathic compounds. Despite these observations and documented evidence, the winter wheat double‐crop soybean system is prevalent in the mid‐South. Investigations are lacking that document physiological differences in soybean plants when preceded by different winter annual crops. This study examined the effect of four winter annual treatments (wheat, canola [Brassica napus L.], barley [Hordeum vulgare L.], and a fallow, non‐planted control) on soybean germination in the laboratory, seedling growth in a greenhouse, and harvest population and grain yield in field experiments at Princeton, KY, from 2014 to 2016. The only consistent finding was detected for seedling growth; soybean roots were shorter and lighter 1 mo after planting when grown in field‐collected soil cores from wheat or barley crops. Differences were not detected for seed germination or seed yield. Based on results of this study and previously unpublished reports, it is possible that the anecdotal differences reported among winter annual crops may be due to an interaction between reduced root growth and environmental conditions, such as limited water or nutrient availability.
Undrained Shear Strength of Unsaturated Soils under Zero or Low Confining Pressures in the Vadose Zone
Authors: Oh Won Taek , Vanapalli Sai 
Published: June 2018

Core IdeasWe present a model to estimate the variation of undrained shear strength of unsaturated soils.Environmental factors influenced the undrained shear strength of unsaturated soils.The proposed model can be implemented into a numerical analysis.In geotechnical engineering practice, many projects such as stability analysis of slopes or trenches and pavement design involve soils in vadose zones at shallow depths, where soils are under unsaturated conditions. For these types of projects, undrained shear strength test results obtained under zero or low confining pressure can be effectively used to analyze the behaviors of unsaturated soils. Experimental procedures to determine the undrained shear strength for different soil suction values, however, is time consuming even under low confining pressure. For this reason, we attempted to develop a semi‐empirical model to predict the undrained shear strength of unsaturated soils at a shallow depth assuming zero confining pressure as a function of soil suction. In addition, existing empirical or semi‐empirical models are also presented along with the characteristic behaviors of unsaturated soils under axial forces at low or zero confining pressures. Finally, the advantages and disadvantages of each model are discussed based on the comparison between the measured undrained shear strengths under zero or low confining pressures with those predicted using the existing and proposed models.
Unbearable Fadistas: António Variações and Fado as Queer Praxis
Authors: Silva Daniel da 
Published: June 2018

António Variações’s first single, Povo que lavas no rio/Estou além (1982), offers a radical version of Amália Rodrigues’s fado “Povo que lavas no rio” (1962). This article considers Variações as fadista in order to think fado as queer praxis. Though Variações's debut release was a commercial success, his turn as fadista provoked critical derision for what, I argue, is a trans formation of the genre’s gendered codes and practices. Variações's queer masculinity gives body and voice to the transgressive sexuality enmeshed within gendered and fetishized repertoires of fado that are most recognizable in the myths and voices of the genre's divas. This article locates Variações within a fado genealogy, from Maria Severa to Amália Rodrigues, of performers who have similarly been unbearable in body and voice. The purpose of this is to draw attention to fado's affective dispersions of sex and reveal how the genre has coalesced in relation to queer tactics and people throughout its history.
