Influence of Glass Microsphere Filler on the Rheological Behavior of an Epoxy Resin
Authors: Kang Y. , Lee W. , Hwang J. , Lee Y. 
Published: April 2018

Abstract
The rheological behavior of epoxy resin filled with glass hollow microspheres was studied using three types of microspheres with different particle size distributions. The shear-rate dependence on viscosity, as well as relative apparent viscosity, of the suspensions was investigated at different microsphere filler loadings. The change in relative viscosity with different types of microsphere loads was also investigated using the established semi empirical model to estimate the critical filler load. It was found that the critical filler load for all suspensions tested depends mostly on the filler size distribution, neither on the average filler size nor on the specific surface area of the filler.

Published: April 2018

Abstract
The crystallization behavior and mechanical properties were investigated by mixing the traditional α-form nucleating agent (sodium benzoate, SB) and commercialized β-form nucleating agent (TMB-5) in isotactic polypropylene (iPP). Mechanical properties were evaluated by universal testing machines. X-ray diffraction (XRD) and differential scanning calorimetry (DSC) were conducted to illustrate the crystallization behavior. Polarized optical microscopy (POM) was adopted to observe the crystal morphologies. The experimental results show that the weight ratio of two types of nucleating agents determines the final crystal structure and mechanical properties of iPP. When the weight ratio of [SB] : [TMB-5] is 4 : 1, the impact strength and flexural modulus of iPP reach a maximum value. Compared with the single component β-form nucleating agent, the compound nucleating agent exhibits significant synergistic effect and shows better mechanical properties. It is expected that this new nucleation system will have potential industrial applications.

Abstract
The fountain flow effect in a mold cavity results in molecular orientation that is likely to create flow-induced residual stresses, warpage of finished products, and excessive shrinkage, thus making it difficult to guarantee high precision control. This study uses a gas counter pressure technique to inhibit fountain flow and employs a visualization mold design to observe the influence of counter pressure on melt flow behavior, in order to discuss the impact of the counter pressure mechanism on the fountain flow. The visualization mold designed herein and the clip cavity help to test the counter pressure mechanism in injection molding, while the observed particles and high-speed camera assist in observing the influence of fluid flow behavior and counter pressure on the fountain flow effect. The study observes and tracks the flow trajectory of particles in the melt, with findings showing that the closer the flow line of the melt is to the mold wall, the shorter the offset distance will be to the outward flip. Moreover, the closer to the center, the longer the offset distance of the outward flip meaning that it flips outwards in the melt-front nearby the center line and stays on the mold wall surface to form a new frozen layer. The melt-front length changes under different counter pressures and different mold temperatures. The front length changes present the inhibitory effect of counter pressure on the fountain flow, which is more apparent at the far gate than at the near gate. The melt-front lengths of the counter pressure of 0 bar at mold temperatures of 40 °C and 20 °C increase 1.5% and 4.7%, respectively, meaning that the thicker the frozen layer, the more apparent the fountain effect.

Published: April 2018

Abstract
Recycling of plastics is becoming more important nowadays due to the increasing amount of waste that is generated worldwide. Post-consumer plastics have a large volume and their harmful effects must be considered. From this perspective, the option of recycling post-consumer plastics has become more and more necessary. The main objective of this research is the selective separation of polypropylene (PP) and high density polyethylene (HDPE). On this basis, various flotation parameters were tested on virgin plastics and optimized conditions were applied to post-consumer plastics. PP particles with a purity of 96.30% were obtained with a recovery rate of 97.4% in virgin polymer separation, while HDPE particles were obtained as the sunken product with 97.38% purity and a recovery rate of 96.3%. Besides, almost all PP and HDPE particles were selectively separated with the highest recovery rates when using 500 g/t calcium lignosulfonate (CLs) as a plasticizer in post-consumer polymer separation. Moreover, water reuse was investigated to determine the recovery and economy of plasticizer without adding extra water during the experiment. Therefore, it can be concluded that this process is environmentally friendly in terms of PP and HDPE recycling and reuse of process water.
Design au Multitudocène

Published: April 2018

Si le design, tout au long du XX e siècle, a stimulé la croissance industrielle avec des projets de développement qui suivaient des idéaux d’universalité, il semble vouloir s’orienter aujourd’hui vers les potentiels de croissance pluriverselle : face aux crises économiques mais aussi écologiques, résistances, résiliences et résurgences font partie des préoccupations et des pratiques des designers contemporains. Elles constituent ce temps de correspondances, de controverses et aussi, de conflits que l’on peut désigner par Multitudocène où suivre les lignes revient surtout à suivre les luttes locales et globales.

Authors: Palo Mansha , Gupta Shweta , Naik Milind N. , Ali Mohammad Javed 
Published: April 2018

Purpose:
To assess the association of congenital nasolacrimal duct obstruction (CNLDO) with mode of birth (vaginal or cesarean).

Methods:

This study was a prospective interventional case series of 200 consecutive cases of CNLDO presenting at a tertiary care center. Data collected include demographics, mode of delivery, elective or emergency cesarean section, primary or secondary cesarean sections, type of CNLDO (simple or complex), management, and outcomes. Statistical significance was set at a
P
value of less than .05.

Results:

Of the 200 consecutive patients, 97 (48.5%) were vaginal deliveries and 103 (51.5%) were cesarean sections. Of the 103 cesarean section patients, 57 (55.3%) were primary cesarean sections and the remaining were secondary cesarean sections. Based on the type of CNLDO, 172 (86%) were simple CNLDO. In general, the current study did not find any significant association between the incidence of CNLDO and mode of delivery. Among the complex CNLDO cohort (n = 28), a significant association was found with cesarean section delivery (
P
= .016); however, no such association was noted when the patients were analyzed with regard to their age at presentation.

Conclusions:
The current study did not find an overall significant association between CNLDO and the mode of delivery; however, the subset of patients with complex CNLDO showed a significant association with cesarean section.

Authors: Qi Dongmei , Gao Lixia , Xie Jing , Yu Tao 
Published: April 2018

Purpose:
To investigate the efficacy of a modified surgical procedure for esotropia fixus with high myopia.

Methods:
Thirteen patients (15 eyes) with esotropia fixus and high myopia who underwent the Jensen procedure for superior and lateral rectus muscles at Southwest Hospital between February 2014 and December 2015 were retrospectively analyzed. Intraoperatively, the superior rectus and lateral rectus muscles were separated up to 12 to 14 mm posterior to their respective insertion. A medial rectus large recession or rectus tenotomy was performed based on the degree of fibrosis of the medial rectus muscle. Postoperative examinations were performed at 1 day, 2 weeks, 3 months, and 6 months.

Results:
On the first postoperative day, 12 eyes (10 patients) were in the primary position (80.0%), 2 eyes (2 patients) exhibited 5° to 10° esotropia (13.3%), and 1 eye (1 patient) exhibited 15° esotropia (6.7%). At the 2-week follow up, 1 eye (1 patient) was lost to follow-up, 9 eyes (7 patients) were in the primary position (64.3%), 3 eyes (3 patients) exhibited 10° esotropia (21.4%), and 2 eyes (2 patients) exhibited 15° to 20° esotropia (14.3%). At the 3-month follow-up, the patient whose ocular alignment was 20° esotropia at 2 weeks was found to have developed 30° esotropia; no change was observed in the other patients. A remarkable improvement in ocular motility was observed in all patients.

Conclusions:
The Jensen procedure for the union of the superior rectus and lateral rectus muscles, using two pairs of sutures applied 12 to 14 mm posterior to their respective insertions, yielded favorable outcomes.

Pneumorrhachis after Recreational Drug Use
Authors: Sethi Bilal Amin , Cooper Jamie 
Published: April 2018

Pneumorrhachis, the presence of air in the spinal canal, is an unusual and alarming radiographic finding. The etiology is most commonly traumatic or iatrogenic but it can occur as a spontaneous phenomenon in association with pneumomediastinum. We report the case of a 16 year old male who presented with throat discomfort and a feeling of altered voice after recreational drug use. Examination confirmed widespread subcutaneous emphysema above the clavicles and plain radiograph and computed tomography imaging confirmed the presence of extensive pneumomediastinum and pneumorrhachis. The patient was managed conservatively and made a full recovery. The clinical and imaging features of spontaneous pneumorrhachis are presented as well as a review of the literature with regard to pathogenesis, management and outcome. Knowledge and understanding of this unusual phenomenon is important to properly direct patient care.

Published: April 2018

Thrombogenic superior vena cava syndrome is an uncommon, dangerous complication of long-standing central venous catheter use. The increased use of central venous catheters has resulted in more non-malignant cases of superior vena cava syndrome across all age groups. We present a 5-year-old male with superior vena cava syndrome associated with acute onset of severe upper extremity and facial swelling, dyspnea, and a right subclavian central venous catheter malfunction. The patient was ultimately treated with percutaneous stenting of the superior vena cava with balloon-expandable Palmaz stents following unsuccessful angioplasty, catheter-directed thrombolysis, and percutaneous thrombectomy. This case highlights a relatively uncommon complication in children from long-term central venous catheter access and describes an emerging, minimally-invasive therapeutic alternative that allows for preservation of age-appropriate superior vena cava luminal diameter as patients grow.

Abstract
PYNOD (also called NLRP10) is a member of the nucleotide-binding domain and leucine-rich repeat containing family. Many members of this family play important roles in the activation and/or regulation of immune and inflammatory responses. We previously showed that PYNOD inhibits the IL-1β secretion in response to microbial infection in PYNOD-transgenic mice. In this study, we generated PYNOD-knockout (KO) mice and further investigated PYNOD’s role in the innate and adaptive immune responses. Similar to wild-type macrophages, PYNOD-KO macrophages produced IL-1β and induced pyroptosis, a caspase-1–dependent programmed cell death, in response to various inflammasome activators and microbial infection. In addition, the PYNOD deficiency did not significantly affect the proliferation or cytokine production of T cells, the delayed-type hypersensitivity responses, the anti-tumor immunity, the Ag-specific Ab production, the cytotoxicity of NK cells, or the maturation, Ag-presenting capacity, or elicited migration of dendritic cells. Furthermore, the steady-state skin self-antigen transport to regional lymph nodes was not impaired in PYNOD-KO mice, suggesting that PYNOD is dispensable for steady-state dendritic cell migration. These results suggested that PYNOD is dispensable for the regulation of innate and adaptive immune responses in mice, unless PYNOD’s expression is highly induced under certain conditions.
‘Walking in the light’ and the missio Dei: Perspectives from the Anglican Church of Kenya
Authors: Knoetze Johannes J. , Mwangi Robinson K. 
Published: April 2018

The East African Revival Movement’s (EARM) socio-ethical belief and practice of walking in the light pervades mainstream Protestant churches in Eastern Africa with its emphasis on public confession of sin, which breeds severe relational consequences. Indeed walking in the light of the EARM has long plagued the Anglican Church of Kenya’s participation in the missio Dei, which brings to the fore two categories of Christians, the saved and unsaved. While walking in the light has been buttressed in the Anglican Church of Kenya it is critical to recognise that the mission of God ought to be the heartbeat of the EARM’s very existence. Accordingly, this article demonstrates that it is not the church that has a mission, but the Triune God that challenges the place of walking in the light in the Trinitarian God. This study, therefore, champions practical holiness by positioning walking in the light in the mission of God. As a result, it redefines the EARM’s religious identity, illustrated by a proper exposition of scripture, Trinitarian worship, discreet confession of sin and moral legalism that provides for informed evangelism and social responsibility.

Published: April 2018

AbstractWe consider the curved 4-body problems on spheres and hyperbolic spheres. After obtaining a criterion for the existence of quadrilateral configurations on the equator of the sphere, we study two restricted 4-body problems, one in which two masses are negligible and another in which only one mass is negligible. In the former, we prove the evidence square-like relative equilibria, whereas in the latter we discuss the existence of kite-shaped relative equilibria.
Adolescentes Autores de Atos Infracionais e o Sentimento de Culpa
Authors: Souza Juliana Marcondes Pedrosa , Moreira Jacqueline Oliveira 
Published: April 2018

O texto trabalha o sentimento de culpa na obra freudiana e a proposta de responsabilidade em Lacan para compreender questões que se apresentam ao adolescente em cumprimento de medida socioeducativa quanto ao seu envolvimento com a criminalidade e transgressão da lei. Perguntamos se a possibilidade de se preocupar com outro pode ser inscrita na forma de uma responsabilização subjetiva ou na forma de um sentimento de culpa em relação ao outro. No acompanhamento desses adolescentes, a importância de se pensar o ato como sintoma nos revela a forma singular como o sujeito adolescente responde ao outro social. Sugerimos o trabalho do analista como recurso de ampliação da palavra do adolescente e, ao mesmo tempo, ampliação dos horizontes políticos-culturais e acesso ao circuito capital. Assim, o seu percurso no cumprimento da medida implicará em um novo projeto de vida, o qual convoca a sociedade para um novo posicionamento.

Tribal people use the flower extract of <em>Caesalpinia pulcherrima<strong> </strong></em>to cure liver, stomach and skin disorders in Indian traditional medicine. This study aimed to evaluate the protective roles of purified quercetin extracted from suspension culture of <em>C. pulcherrima</em> against selected bacterial and fungal pathogens. A simple protocol was developed for callus production using leaf explants<em>.</em> 2, 4-D (2.5 mg/l), BAP (2.5 mg/l) + kin (1 mg/ml) was effective for optimal callus induction. Subsequently, cell suspension culture was established. Role of effect of elicitors in cell suspension culture was carried. Sucrose, ABA and salicylic acid (SA) at different concentrations influenced cell biomass and quercetin accumulation. Cells cultured in the medium fortified with 45 g/L sucrose without ABA/SA showed the highest quercetin content (16.5 mg/g). Flavonoids was purified, fractionated by HPLC-DAD followed by NMR revealed the presence of quercetin, isoquercetin, quercetrin, rutin, quercetin 3-O-β-D-xyloside, quercetin 3-Oarabinopyranoside, quercetin 3-O- α-arabinopyranosyl (1→2) β-galactopyranoside, isorhamnetin 3-O-rutinoside and an unknown compound. Subsequently, anthocyanin was evaluated for antimicrobial activity against selected Gram-positive bacteria (<em>S. aureus, Bacillus subtilis</em>, and <em>Enterococcus faecalis</em><em>)</em>, Gram-negative bacteria (<em>E. coli, </em>and <em>Pseudomonas aeruginosa</em>) and fungi such as <em>Aspergillus flavus, Candida albicans </em>and <em>Trichophyton rubrum</em>. Quercetin was found to be active against four bacteria and the fungi- <em>Candida albicans</em>. The highest inhibitory effects were found on <em>S. aureus</em> and <em>Enterococcus faecalis</em>. Gram negative bacteria showed more resistance i.e., with insignificant MIC and MBC values. Among the fungi, <em>Aspergillus flavus</em> and <em>Trichophyton rubrum</em> displayed remarkable MIC and MKC values. These results suggest that quercetin may be used as a natural antimicrobial agent. Future works are designed to trace the molecular mechanism of antimicrobial potentiality of quercetin against these tested pathogens
