Authors: Li Ming , Du Wenchao , Elwany Alaa , Pei Zhijian , Ma Chao 
Published: November 2019

Abstract
Binder jetting, also known as 3D printing, is an additive manufacturing (AM) technology utilizing a liquid-based binding agent to selectively join the material in a powder bed. It is capable of manufacturing complex-shaped parts with a variety of materials. This paper provides an overview of binder jetting of metals with a discussion about the knowledge gaps and research opportunities. The review deals with two parameter categories in terms of the material and process and their impacts. The achieved density, dimensional accuracy, and mechanical strength are summarized and analyzed. Further in-depth consideration of densification is discussed corresponding to various attributes of the packing, printing, and sintering behaviors. Though binder jetting has attracted increasing attention in the past several years, this fabrication process is not well studied. The understanding of powder spreading process and binder-powder interaction is crucial to the development of binder jetting but insufficient. In addition, the lack of investigation on the mechanical behavior of binder jetting metal part restricts the actualization of its wide-range applications.

Abstract
Additive manufacturing (AM) of metal has been experiencing rapid growth in recent years by employing a variety of techniques. Among them, selective laser melting (SLM) of metal exhibits advantages in terms of its capabilities to build complex geometries, good surface finish, and high dimensional accuracy. Due to these benefits, SLM has demonstrated the ability to create metallic parts that can be applied in aerospace, automotive, and medical industries. However, most parts are geometrically complex with curved surface features, which would be difficult to be fabricated through traditional manufacturing methods. In order to increase the adoption and effectiveness of SLM for metal parts fabrication, the as-built surface finish and dimensional accuracy of the parts with curved surface features should be well understood. Great attempts have been made to investigate the surface texture of SLM as-built parts with various surface types. Most investigations characterize the surface texture of SLM-fabricated specimens with planar surface features. However, little is known about the surface finish and dimensional accuracy of SLM-fabricated metal parts with curved surfaces. Directly applying knowledge derived from planar surfaces to curved ones can be misleading. In this work, stainless steel 316L parts with curved surface features were built using SLM to examine the surface finish and dimensional accuracy. The results showed that 11 surface texture variables were significant at five different curvatures and the three most significant roughness variables were Sk, Spc, and Vmc. It was found that curvatures C1 and C5 significantly differed from the other curvatures (C2, C3, and C4) in all the 11 surface texture variables. In addition, the thickness of the as-built curved surface part at varied curvature locations would be almost constant.
Binder Jetting Additive Manufacturing of Ceramics: Feedstock Powder Preparation by Spray Freeze Granulation

Abstract
Objective of this study is to prepare the binder jetting feedstock powder by spray freeze drying and study the effects of its parameters on the powder properties. Binder jetting additive manufacturing is a promising technology for fabricating ceramic parts with complex or customized geometries. However, this process is limited by the relatively low density of the fabricated parts even after sintering. The main cause comes from the contradicting requirements of the particle size of the feedstock powder: a large particle size (&gt; 5 μm) is required for a high flowability while a small particle size (&lt; 1 μm) for a high sinterability. For the first time, a novel technology for the feedstock material preparation, called spray freeze drying, is investigated to address this contradiction. Using raw alumina nanopowder (100 nm), a full factorial design at two levels for two factors (spraying pressure and slurry feed rate) was formed to study their effects on the properties (i.e., granule size, flowability, and sinterability) of the obtained granulated powder. Results show that high pressure and small feed rate lead to small granule size. Compared with the raw powder, the flowability of the granulated powders was significantly increased, and the high sinterability was also maintained. This study proves that spray freeze granulation is a promising technology for the feedstock powder preparation of binder jetting additive manufacturing.

Published: November 2019

Abstract
Many industries, such as human-centric product manufacturers, are calling for mass customization with personalized products. One key enabler of mass customization is 3D printing, which makes the flexible design and manufacturing possible. However, personalized designs bring obstacles for the shape matching and analysis, owing to the high complexity and large shape variations. Traditional shape matching methods are limited to shape alignment, which cannot determine the intrinsic in-variance of mass customized models. To extract the deformations widely seen in mass customization paradigm and address the issues of alignment methods in shape matching, we redefine the geometry matching problem as a correspondence problem, and solve for the correspondence of all vertices on a queried shape to a reference shape. A state-of-the-art geometric deep learning method is used to learn the correspondence of a set of collected models. Through learning the intrinsic deformations of the products, the underlying variations of the shapes are extracted. We demonstrate the application of the proposed approach in orthodontics industry, and the experimental results show the effectiveness of the proposed method and the defined problem is favorably suitable for shape analysis in mass customization.

Published: November 2019

Abstract
Carbon fiber reinforced plastic (CFRP) composites were widely used in machinery, automobile, and aerospace industries due to the superior properties of high stiffness, high strength-to-weight ratio, high fatigue resistance, and good wear resistance. In these applications, hole making on CFRP composites was needed for assembly purpose. In different hole making processes, delamination was considered as a crucial issue, leading to premature failure of products. Compared with the conventional CFRP hole making processes (such as twist drilling, milling, grinding, etc.), rotary ultrasonic machine (RUM) had advantages of low cutting force and torque, low surface roughness, and long tool life. Therefore, numbers of researchers worked on RUM processes. The reported investigations mainly focused on the effects of input variables (including machining variables, tool variables, and workpiece properties) on cutting force, torque, surface roughness, and tool life, etc. In addition, effects of cutting tool variables on delamination were also reported. However, there were no reported investigations on effects of machining variables on delamination in RUM of CFRP composites. This investigation, for the first time, reported the effects of ultrasonic power, tool rotation speed, and feedrate on delamination as well as its associated cutting force. Based on the experiments, the results showed that delamination decreased with ultrasonic power increasing, tool rotation speed increasing, or feedrate decreasing. The relationships between cutting force and delamination were also studied.

Abstract
The objective of this paper is to experimentally validate the graph-based approach that was advanced in our previous work for predicting the heat flux in metal additive manufactured parts. We realize this objective in the specific context of the directed energy deposition (DED) additive manufacturing process. Accordingly, titanium alloy (Ti6Al4V) test parts (cubes) measuring 12.7 mm × 12.7 mm × 12.7 mm were deposited using an Optomec hybrid DED system at the University of Nebraska-Lincoln (UNL). A total of six test parts were manufactured under varying process settings of laser power, material flow rate, layer thickness, scan velocity, and dwell time between layers. During the build, the temperature profiles for these test parts were acquired using a single thermocouple affixed to the substrate (also Ti6Al4V). The graph-based approach was tailored to mimic the experimental DED process conditions. The results indicate that the temperature trends predicted from the graph theoretic approach closely match the experimental data; the mean absolute percentage error between the experimental and predicted temperature trends were in the range of 6% ∼ 15%. This work thus lays the foundation for predicting distortion and the microstructure evolved in metal additive manufactured parts as a function of the heat flux. In our forthcoming research we will focus on validating the model in the context of the laser powder bed fusion process.

Abstract
Glass-to-metal seals are important in hermetic electrical feedthroughs for high-temperature and high-pressure applications. Traditionally, glass-to-metal seals are created using a high temperature furnace with controlled pressure and atmosphere. Current manufacturing techniques for glass-to-metal seals require precise fixturing (limiting unitization) and face restrictions in terms of the coefficient of thermal expansion for the glass/metal system. This paper explores the potential to use a laser to locally heat the glass as the first step toward the additive manufacturing of glass to metal seals. Studies are conducted fusing both frit and preforms under ambient conditions. The effects of process parameters on the process are quantified. The paper shows the potential of the process using Selective Laser Melting equipment, which can lead to greater flexibility for glass-to-metal seals with respect to geometry, materials, and spatially varying properties.

AbstractObjectiveTo examine the association of consumption of dairy foods with risk of total and cause specific mortality in women and men.DesignThree prospective cohort studies with repeated measures of diet and lifestyle factors.SettingNurses’ Health Study, Nurses’ Health Study II, and the Health Professionals Follow-up Study, in the United States.Participants168 153 women and 49 602 men without cardiovascular disease or cancer at baseline.Main outcome measureDeath confirmed by state vital records, the national death index, or reported by families and the postal system. During up to 32 years of follow-up, 51 438 deaths were documented, including 12 143 cardiovascular deaths and 15 120 cancer deaths. Multivariable analysis further adjusted for family history of cardiovascular disease and cancer, physical activity, overall dietary pattern (alternate healthy eating index 2010), total energy intake, smoking status, alcohol consumption, menopausal status (women only), and postmenopausal hormone use (women only).ResultsCompared to the lowest category of total dairy consumption (average 0.8 servings/day), the multivariate pooled hazard ratio for total mortality was 0.98 (95% confidence interval 0.96 to 1.01) for the second category of dairy consumption (average 1.5 servings/day), 1.00 (0.97 to 1.03) for the third (average 2.0 servings/day), 1.02 (0.99 to 1.05) for the fourth (average 2.8 servings/day), and 1.07 (1.04 to 1.10) for highest category (average 4.2 servings/day; P for trend <0.001). For the highest compared to the lowest category of total dairy consumption, the hazard ratio was 1.02 (0.95 to 1.08) for cardiovascular mortality and 1.05 (0.99 to 1.11) for cancer mortality. For subtypes of dairy products, whole milk intake was significantly associated with higher risks of total mortality (hazard ratio per 0.5 additional serving/day 1.11, 1.09 to 1.14), cardiovascular mortality (1.09, 1.03 to 1.15), and cancer mortality (1.11, 1.06 to 1.17). In food substitution analyses, consumption of nuts, legumes, or whole grains instead of dairy foods was associated with a lower mortality, whereas consumption of red and processed meat instead of dairy foods was associated with higher mortality.ConclusionThese data from large cohorts do not support an inverse association between high amount of total dairy consumption and risk of mortality. The health effects of dairy could depend on the comparison foods used to replace dairy. Slightly higher cancer mortality was non-significantly associated with dairy consumption, but warrants further investigation.

ObjectiveTo determine whether patients from the Vascular Quality Initiative (VQI) registry who are Medicare–Medicaid dual-eligible have outcomes after surgical intervention with medical devices such as stents for peripheral artery disease comparable to the outcomes of those eligible for Medicare alone.MethodsThe study cohort included fee-for-service Medicare beneficiaries from 2010 to 2015 who underwent peripheral vascular intervention as determined by the VQI. We performed propensity matching between the dual-eligible and non-dual-eligible cohorts. Postintervention use, including imaging, amputation and death, was determined using Medicare claims data.ResultsRates of major amputation were higher among dual-eligible patients (13.0% vs 10.5%, p<0.001), while time to amputation by disease severity was similar (p=0.443). For patients with more advanced disease (critical limb ischaemia (CLI) vs claudication), dual-eligible patients have significantly faster times to any amputation and death (p<0.001). For of postoperative imaging, 48.4% of dual-eligible patients receive at least one postoperative image, while the percentage for non-dual-eligible patients is 47.2% (p=0.187).ConclusionsPatients with mild forms of peripheral artery disease (PAD), such as claudication, demonstrated similar outcomes regardless of dual-eligibility status. However, those with severe PAD, such as CLI, who were also dual-eligible had both inferior overall survival and amputation-free survival. Minimal differences were observed in process-driven aspects of care between dual-eligible and non-dual-eligible patients, including postoperative imaging. These findings indicate that despite receiving similar care, dual-eligible patients with severe PAD have inferior long-term outcomes, suggesting the Medicaid safety net is not timely enough to benefit from long-term outcomes for these patients.
Gender in Biblical Studies: a Brief Overview
Authors: Edwards Katie , Stiebert Johanna 
Published: November 2019

AbstractThis article provides background and context for the ensuing contributions in this special journal edition, the focus of which is gender studies and the Dead Sea Scrolls. While the discovery and study of the Scrolls has certainly revolutionized Biblical Studies, the study of the Scrolls is nevertheless often perceived and treated as a subsidiary, even marginalized, field of Biblical Studies, rather than as either an integral part thereof, or as a discipline in its own right. This article aims to highlight how gender has been studied with reference to the Bible. Subsequent contributions demonstrate how gender is shaping interpretations of the Scrolls.
Reassessment of taxonomic characters for the plant bug genus Hypseloecus Reuter, with descriptions of new species of Hypseloecus and the related genus Lasiolabops Poppius (Heteroptera: Miridae: Phylinae)
Authors: Yasunaga Tomohide , Duwal Ram Keshari 
Published: November 2019

The Old World plant bug genus Hypseloecus Reuter of the tribe Pilophorini is reviewed on the basis of detailed observation of the morphological characters, with an updated checklist of Asian congeners. “Pleural glands” are herein suggested as a novel diagnostic character and currently considered as an additional autapomorphy for the genus. Two Asian new species, Hypseloecus nakagawai sp. n. (from Honshu, Japan) and H. aaroni sp. n. (Bagmati Zone, Nepal), are diagnosed and described. The host association and habitat of H. nakagawai are also documented. An Old World pilophorine genus, Lasiolabops Poppius, assumed to be a potential sister taxon of Hypseloecus, is diagnosed and discussed; further, two new species, L. cirratus sp. n. (from Japanese Ryukyus) and L. remicornis sp. n. (from Central Thailand), are described, based on their distinctive vestiture pattern.
شكاوى موظفي الدولة الأشورية الحديثة إلى الملك أو لولي العهد (قبل الميلاد ٦١٢ – ٧٢١)

Published: November 2019

Justice is one of the Assyrian Kings’ titles during the Sargon II Dynasty, 721–612 BCE. They used to say that they loved justice. Despite the existence of courts and judges, high-ranking officials and astrologers prefer to complain to the King directly using their association with the King to state their problem, sometimes between lines or at the end of the report. Most of the cases are concerned with either estate or other affairs.This paper focused on those cases; unfortunately in most cases we do not know the King’s orders except in some cases when the officials were not satisfied with the judge’s verdict, therefore they complain again and mention the King’s order as an indirect speech in the same letter.
نقش كتابي بصهريج يعقوب شاه المهمندار بالقاهرة، يسجل مآثر السلطان قايتباي المعمارية والحربية م) ١٤٩٦-١٤٩٥ /ھ ٩۰۱)

This is an extensive study about the inscription of the cistern of Yacqūb Shāh al- Mihmandār in Cairo (901 AH/1495–1496 CE). This Cistern is a small building existing at the foot of the Citadel; however, it is a very important building, not only for its function but also for the content of its inscriptions. Despite that there are previous studies of the inscription, they are brief studies. Therefore, it should be restudied in a comprehensive manner.The inscription showed that the building at the time of construction was a dual cistern with double domes, established by Yacqūb Shāh al-Mihmandār (one of Amirs during the reign of the Sultan Qāyt Bāy, and is one of the loyal friends of this Sultan). Although the inscription is a construction text, it is considered a documentary and ceremonial text. It recorded the religious and knighthood achievements of Sultan Qāyt Bāy, which made him surpass his peers of kings and sultans, and recorded the military and architectural accomplishments of the same Sultan. For example, in Makkah, Sultan Qāyt Bāy reconstructed Masjid al-Khayf (Al-Khayef) in the south of Mina (873/1467), and also restarted the flow of the aqueduct of Arafa (Ain Zubaidah). In Medina, he reconstructed the Prophet’s Mosque. In Jerusalem, he restarted the flow of the aqueduct of el-Sabīl. Afterwards, the inscription is completed by an epic report about the victory of the Mamluk Army versus the Ottoman Army in the Battle of Adana (891 AH/1486 CE), and the capture of the commander of the Ottoman Army, Hersekzāde Ahmed, bringing him to Cairo in a humiliating manner.

Published: November 2019

Objective: The aim of this study was to assess the effect of Full Plate Diet (FPD) on the primary prevention of cardio-metabolic risk factors. Design: Randomised clinical trial. Setting: Drayson Center, Loma Linda University, CA, USA. Methods: Forty individuals were randomly assigned to either an intervention group receiving the FPD health education for 10 weeks or to a control group not receiving this intervention. Comprehensive evaluations of clinical and anthropometric outcomes were conducted at baseline and at the end of intervention. To assess within-group changes and between-group differences, a general linear model was used. Results: Significant reductions in weight (−1.54 kg, 95% confidence interval [CI] −2.5, −.54) and total cholesterol (TC) (−11.7 mg/dL; 95% CI −21.4, −2) and non-significant reductions in means for low-density lipoprotein cholesterol (LDL-C) (−7.3 mg/dL, 95% CI −16, 1.5) and triglycerides (−18.7 mg/dL, 95% CI −46, 8.5) were observed in the intervention group after 10 weeks compared with baseline. These reductions were non-significantly higher in the intervention compared with the control group. There were no significant mean changes in systolic and diastolic blood pressure, high-density lipoprotein cholesterol (HDL-C) and haemoglobin A1c (A1c) in the intervention group after 10 weeks. Conclusion: A multi-component programme comprising 10 weeks of health education that emphasised the high intake of fibre failed to significantly reduce cardio-metabolic risk factors. It did show a downward trend in triglycerides, TC and body weight that may be of clinical importance suggesting that a future investigation with a longer intervention duration is needed.

Published: November 2019

Objective To develop a liquid chromatography-tandem mass spectrometry (LC-MS/MS) method for the quantification of voriconazole in human plasma, and to evaluate its application in clinical therapeutic drug monitoring. Method Plasma samples were obtained from Chinese patients receiving voriconazole, precipitated with methanol (using fluconazole as an internal standard), and then subjected to LC-MS/MS using an SB C18 column with a methanol and water mobile phase at a flow rate of 0.4 mL/minute. Quantification was performed by multiple-reaction monitoring using the precursor and product ion pair m/z 350–280.9 for voriconazole and m/z 307–219.9 for fluconazole. Results The calibration curve was linear over a range of 0.1–10.0 µg/mL (R2 = 0.9995). The inter-day and intra-day relative standard deviations were <7.68% and <8.97%, respectively. Extraction recovery, matrix effect, and stability were also validated. Sixty-eight plasma samples from 42 patients were analyzed, and the voriconazole concentrations in 25 samples (36.8%) were outside the optimal range of 1.5–4.5 µg/mL. Conclusions We developed a simple and accurate method of drug monitoring, which could improve the efficacy and prevent adverse reactions of voriconazole.
