High-density assembly and root cause analyses

Implementing high-density assembly in all electronic products requires many considerations. Before starting any development work or implementing a new technology, it is critical to understand the product and industry requirements and capabilities. If this is not fully understood, failure is the most probable outcome. This paper will discuss selection of the correct solder paste based on the end product and the need to conduct proper root cause analyses before making any material or process changes.
Pattern of genito-urinary parasitic infections at the Teaching Hospital, Sokoto, Nigeria.

Urinary schistosomiasis was more frequently observed among subjects aged 10-19 years old; and the degree of exposure to the infection was found to be high among the males. Comparative analysis of T. vaginalis infection among the females revealed a ten-fold increase in the detection rate for the flagellate in the urine samples collected from the Special Treatment Clinic than those from Out-patient department. The age-specific morbidity pattern for Trichomonal vaginitis was remarkably high among females of maximum sexual activity (i.e. 20-29 years old), 6(12.24%) and 4(8.16%) of the 49 cases of Trichomonal vaginitis had mixed infections with Neisseria gonorrhoae and Candida albicans respectively. The association between detection of haematuria, proteinuria and urinary schistosomiasis was supported. Age, sex and social behaviour were identified as important determining factors on pattern of genito-urinary parasitic infections.
Ultra-Wideband CMOS Differential Colpitts VCO with adaptive gm bias for the 60GHz WPAN

A Ultra-Wideband CMOS Differential Colpitts VCO for 60GHz WPAN fabricated with the 90nm TSMC Process is presented. The VCO is composed of a NMOS transistor-pair as a core circuit, 3 bit capacitor array for enhancement of the oscillation bandwidth, and adaptive gm bias for desensitizing process variations. The proposed architecture can operate at 28∼34GHz and the phase noise at 1MHz offset is −112dBc/Hz. The power consumption of the VCO including inherent buffer is 21.6mW. Compared with previous studied works, the proposed VCO has the widest bandwidth at mm-Wave frequency.
A New Approach to CSR: Company Stakeholder Responsibility

Assume that the CEO of Firm A is asked the following: ‘Well, I know that your company makes products that consumers like, and that those products make their lives better. And I know that suppliers want to do business with your company because they benefit from this business relationship. I also know that employees really want to work for your company, and are satisfied with their remuneration and professional development. And, let’s not forget that you’re a good citizen in the communities where you are located;2 among other things, you pay taxes on the profits you make. You compete hard but fairly. You also make an attractive return on capital for shareholders and other financiers. However, are you socially responsible? ’
How to become an employer of choice: transforming employer brand associations into employer first-choice brands

Abstract Being a first-choice brand is a valuable asset for an organisation, both for remaining competitive and for attracting potential employees. Despite the considerable research available on linking brand associations to employer brand attractiveness, research on how to become an employer of choice is limited. This article addresses the research gap by investigating employer brand associations that predict status as an employer first-choice brand (FCBe), and by determining how these associations are transferred into preference. Research was based on university students’ evaluations of employer brand associations and identification of their FCBe. Results indicate that work content and work culture of employer brand associations are drivers of being an FCBe, with no support found for effects of salary, advancement opportunities, location or organisational reputation. Importantly, employer brand emotions emerged as a full mediator in the model, indicating that for an FCBe, work content and work culture need to be linked to emotions. These results suggest that only if employer brand associations lead to positive employer brand emotions can an FCBe be established. This study contributes to the literature by being the first to investigate drivers of employer first-choice brand, and to identify employer brand emotions as essential for establishing an FCBe.
Language and gender influence on the consumer choice of branded meat attributes

The feedlot industry is the main beef producer in South Africa and falls in the category of Small Businesses. For these small business enterprises to be successful in an industry subjected to fierce competition, it is necessary to be innovative in a market where high quality beef serves as just another commodity. Previous research has shown that demographic factors can influence brand preferences. The objective of this study was to investigate the relationships between language and gender with brand attribute preference. Another objective was to identify opportunities that will differentiate and position branded meat products that will create consumer equity and build strong brand names. The case study approach was used and included quantitative and qualitative research. The population consisted of consumers buying meat products at the different retailers in Middelburg, Mpumalanga, under the brand names Kanhym Fresh Meat, Farm Inn Meat, and Franks Meat. A sample of 612 was conveniently selected for the study. A total of 588 questionnaires were completed. This study confirmed the interrelationship of the demographic variables gender and language that may affect consumers preferences. This means consumers will try different products with specific attributes. The results of this study identify opportunities of implementing strategies to maintain and enhance the competitiveness of branded meat retailers. It is finally recommended that brand retailers determine the demographic and psychographic profile of their target market for a specific product when producing or marketing products.
Methyl 2-(5-chloro-1-methyl-2-oxo-2,3-dihydro-1H-indol-3-ylidene)acetate

The title compound, C12H10ClNO3, the indoline ring system is essentially planar, with a maximum deviation of 0.009 Å for the N atom. The indoline ring and acetate group are essentially coplanar, with a maximum deviation of 0.086 Å for the O atom. The mean plane through the methoxycarbonylmethyl group forms a dihedral angle of 3.68 (5)° with the plane of the indoline ring system. The molecular structure is stabilized by an intramolecular C—H⋯O hydrogen-bond interaction. In the crystal, π–π stacking interactions [centroid–centroid distance = 3.7677 (8) Å] occur between benzene rings, forming a chain running along the c-axis direction.
A Visual Analytic System for Comparing Attention Patterns in Eye-Tracking Data

In this work we present a novel approach of analyzing eye tracking data through temporal analysis of fixation data. We adopt a general visual analytic system called Glyph that facilitates comparison of abstract data sequences to understand group and individual patterns. Using such a system, researchers can understand how users shift in their fixations and dwelling given different stimuli, and how different user groups differ in terms of these temporal eye tracking patterns. In this paper we discuss the system using a case study of eye tracking experiment used to investigate emotion regulation among different age groups through the study of attention to different parts of a video. Temporal patterns for such a study presents a plus on other eye tracking analysis methods.
Induction of transmissible gastroenteritis coronavirus-neutralizing antibodies in vitro by virus-specific T helper cell hybridomas.

Three transmissible gastroenteritis (TGE) virus-specific T helper (Th) cell hybridomas have been generated from virus-primed BALB/c mice, by fusion with the thymoma BW5147. The hybridomas responded to purified u.v. -inactivated TGE virus with interleukin production and growth inhibition. TGE virus recognition by the hybridomas was restricted by the major histocompatibility complex: only splenocytes from syngeneic or semi-syngeneic mice were able to recognize the antigen. The three hybridomas were Thy 1.2+, but did not express detectable levels of Lyt 1 or Lyt 2 antigens by fluorescent cell sorting analysis. Only one hybridoma (T.1J.B5) expressed the L3T4 marker. These hybridomas had helper activity, as they were able to reconstitute in vitro the synthesis of TGE virus-specific antibodies by Th cell-depleted spleen cells from immune BALB/c mice. The antibodies that they induced specifically neutralized by 10(3)- to 10(4)-fold the infectivity of TGE virus, ruling out the possibility of inhibition of virus replication by interferon. These hybridomas could be very useful for identifying antigenic domains in TGE virus recognized by Th cells, which cooperate with B cells in the synthesis of neutralizing antibodies.
Sensitivity evaluation of the visual, tactile, and auditory detection response task method while driving

ABSTRACT Objectives: In this article, we evaluate the sensitivity to cognitive load of 3 versions of the Detection Response Task method (DRT), proposed in ISO Draft Standard DIS-17488. Methods: We present a user study with 30 participants in which we compared the sensitivity to cognitive load of visual, audio, and tactile DRT in a simulated driving environment. The amount of cognitive load was manipulated with secondary n-back tasks at 2 levels of difficulty (0-back and 1-back). We also explored whether the DRT method is least sensitive to cognitive load when the stimuli and secondary task are of the same modality. For this purpose, we used 3 forms to present the n-back task stimuli: visual, audio, and tactile. Responses to the task were always vocal. The experiment was based on a between-subject design (the DRT modalities) with 2 levels of within-subject design study (modalities and difficulty of the secondary n-back tasks). The participants' primary task in the study was to drive safely, and a second priority was to answer to DRT stimuli and perform secondary tasks. Results: The results indicate that all 3 versions of the DRT tested were sensitive to detecting the difference in cognitive load between the reference driving period and driving and engaging in the secondary tasks. Only the visual DRT discriminated between the 0-back and 1-back conditions on mean response time. Contrary to expectations, no interaction was observed between DRT modality and the stimuli modality used for presentation of the secondary tasks. Conclusions: None of the 3 methods of presenting DRT stimuli showed a consistent advantage in sensitivity in differentiating multiple levels of cognitive load if all response times, hit rates, and secondary task performance are considered. If only response time is considered, the visual presentation of the DRT stimulus used in this study showed some advantages. In interpreting these data, it should be noted that the methods of DRT stimulus presentation varied somewhat from the currently proposed draft ISO standard and it is possible that the relative salience level of the visual DRT stimulus influenced the findings. It is further suggested that more than 2 levels of difficulty of the n-back task should be considered for further investigation of the relative sensitivity of different DRT stimuli modalities. Parameters that indicate change in cognitive load (response time, hit rate, task performance) should be analyzed together in assessing the overall impact on the driver and not individually, in order to obtain a fuller insight of the assessed cognitive load.
A survey of plasmids among natural isolates of Streptomyces.

The possible involvement of plasmid DNA in the biosynthesis of antibiotics in Streptomycetaceae has been intensively studied, and plasmids have been isolated from many antibiotic-producing Streptomyces.1--13) However no strong evidence has been found which proves that plasmids play a part in the biosynthesis of any antibiotic except for methylenomycin14). To study the possible role of plasmids in antibiotic production, we examined 120 newly-isolated strains of Streptomyces for the presence of plasmids; the antibiotic-producing abilities of each strain were determined and correlated with the presence of a
Low‐dose ketamine failed to spare morphine after a remifentanil‐based anaesthesia for ear, nose and throat surgery

Background: Ketamine has been claimed to prevent acute opioid tolerance and hyperalgesia following acute exposure to opioids and its use has been proposed to decrease postoperative morphine consumption. Methods: We conducted a randomized, double‐blind, controlled study to evaluate the effect of intravenous (i.v.) ketamine on postoperative pain for 48 h after major ear, nose and throat (ENT) surgery. Thirty‐one patients received i.v. ketamine 0.15 mg kg−1 before induction and 2 μg kg−1 min−1 during anaesthesia, and 31 patients were administered placebo in a similar manner. Anaesthesia was standardized with remifentanil and propofol, but without nitrous oxide. Standardized postoperative analgesia included paracetamol, methylprednisolone and morphine administered via a patient controlled analgesia (PCA) device. Results: Intra‐operative remifentanil consumption was not different between the ketamine group (0.25 ± 0.07 μg kg−1 min−1) and the control group (0.22 ± 0.07 μg kg−1 min−1). In the postoperative period, both groups experienced an identical pain course evolution. Cumulative morphine consumption was not significantly different between groups: at 24 h it was 33.3 ± 14.9 with ketamine and 31.9 ± 15.3 mg in controls, at 48 h it was 40.4 ± 20.6 mg with ketamine and 42.5 ± 25.9 mg in controls. Conclusion: Low‐dose ketamine added to a remifentanil‐based propofol anaesthesia did not reduce morphine consumption after major ENT surgery.
A gain-enhanced microstrip-fed cavity-backed slot antenna

This paper describes a gain-enhanced cavity-backed slot antenna. A superstrate of high permittivity is placed at a certain distance above the substrate to enhance the gain of the slot antenna. The cavity-backed slot antenna is fed by a microstrip line printed on the top of the substrate. Both simulation results and experimental measurements show that this superstrate-covered cavity-backed slot antenna can attain a high gain, while it retains the broadband impedance characteristics.
The efficacy of primary care chaplaincy compared with antidepressants: a retrospective study comparing chaplaincy with antidepressants

Aim To determine the effectiveness of primary care chaplaincy (PCC) when used as the sole intervention, with outcomes being compared directly with those of antidepressants. This was to be carried out in a homogenous study population reflective of certain demographics in the United Kingdom. Background Increasing numbers of patients are living with long-term conditions and ‘modern maladies’ and are experiencing loss of well-being and depression. There is an increasing move to utilise non-pharmacological interventions such as ‘talking therapies’ within this context. Chaplaincy is one such ‘talking therapy’ but within primary care its evidence base is sparse with only one quantitative study to date. There is therefore a need to evaluate PCC excluding those co-prescribed antidepressants, as this is not evidenced in the literature as yet. PCC also needs to be directly compared with the use of antidepressants to justify its use as a valid alternative treatment for loss of well-being and depression. Methods This was a retrospective observational study based on routinely collected data. There were 107 patients in the PCC group and 106 in the antidepressant group. Socio-demographic data were collected. Their pre- and post-intervention (either chaplaincy or antidepressant) well-being was assessed, by the Warwick-Edinburgh Mental Well-being Scale (WEMWBS) which is a validated Likert scale. Findings The majority of both groups were female with both groups showing marked ethnic homogeneity. PCC was associated with a significant and clinically meaningful improvement in well-being at a mean follow-up of 80 days. This treatment effect was maintained after those co-prescribed antidepressants were removed. PCC was associated with an improvement in well-being similar to that of antidepressants with no significant difference between the two groups.
Histamine, mast cells, and the enteric nervous system in the irritable bowel syndrome, enteritis, and food allergies

There is altered expression of histamine H1 and H2 receptor subtypes in mucosal biopsies from the terminal ileum and large intestine of patients with symptoms of food allergy and/or irritable bowel syndrome The research article by Sander and colleagues1 in this issue of Gut , reports their results for expression of histamine receptor subtypes in the human intestinal tract from normal individuals and patients with symptoms of the irritable bowel syndrome (IBS) and/or food allergies (see page 498) . Work of this nature was overdue because most of the available histological and functional data for histamine receptors in the small and large intestine were obtained from animal models. The authors’ principal findings for the human bowel are in general agreement with the animal literature that reports on expression of the histamine H1, H2, and H4 receptor subtypes in the enteric nervous system (ENS), intestinal musculature, mucosal epithelium, and immune/inflammatory cells. In contrast, the finding by Sander and colleagues1 that histamine H3 receptors are not expressed in the human bowel was unexpected in view of the clearcut evidence for functional involvement of the H3 receptor subtype in the nervous control of motility, secretion, and blood flow in guinea pig intestine, which serves as the primary animal model.2–5 The authors’ evidence for altered expression of histamine H1 and H2 receptor subtypes in mucosal biopsies from the terminal ileum and large intestine of patients with symptoms of food allergy and/or IBS is consistent with current concepts for the involvement of histamine release from enteric mast cells and its paracrine signalling function in the ENS as an underlying factor in these two disorders.5–8 Histamine is not expressed by enteric neurones and is not a neurotransmitter in …
Characterization of the RcsC→YojN→RcsB Phosphorelay Signaling Pathway Involved in Capsular Synthesis in Escherichia coli

Escherichia coli and other enteric microorganisms produce an extracellular polysaccharide capsule, called colanic acid, under certain environmental conditions. This capsular synthesis is regulated by the RcsC (sensor kinase)→YojN (phosphotransfer intermediate)→RcsB (response regulator) phosphorelay signal transduction under certain growth conditions. Nonetheless, little is known about signals that exaggerate the Rcs-system. To gain insight into signals that activate the Rcs-system, here we searched for genes that activate the Rcs-system, provided that those on a multicopy plasmid were introduced into E. coli. We identified several such genes, namely, rcsB, rcsA, djlA, lolA, and ompG. The DjlA, LolA, and OmpG proteins are particularly interesting in that they are all located on the cell surface, where the primary sensor RcsC histidine-kinase is localized. Implications of these findings are discussed with special reference to the mechanism by which RcsC perceives external signals.
Staining and morphologic features of bone marrow hematopoietic cells in desert tortoises (Gopherus agassizii).

OBJECTIVES To determine optimal site for collection of bone marrow from desert tortoises, and to characterize cytologic staining and morphologic features of bone marrow hematopoietic cells. ANIMALS 16 desert tortoises. PROCEDURE Bone marrow was obtained at necropsy from the pelvis, proximal portion of the humerus, femur, and thickened portions of the cranial to craniolateral and caudal to caudolateral margins of the carapace and plastron for histologic and cytologic examinations. Cytocentrifuged preparations of marrow cells were evaluated for reactivity to cytochemical stains. RESULTS Histologic sections were adequate for evaluating acidophils, acidophil precursors, and erythrocyte precursors. It was difficult to differentiate among monocytes, lymphocytes, thrombocytes, and blast cells, and eosinophils could not be differentiated from heterophils. Basophils were in rare, small clusters of 3 to 12 cells. A few lymphoid follicles were found in the pelvis and long bones. Use of cytochemical staining accomplished differentiation between agranular heterophil precursors and granulated heterophils, and between granulated eosinophils and basophils. Monocytes, azurophils, and monoblasts had similar staining features. Staining of erythrocyte precursors with Sudan black B differentiated them from lymphocytes. Only a few small cells with periodic acid-Schiff-positive cytoplasm were identified as thrombocytes. Lymphocytes did not stain with any of the cytochemical stains. CONCLUSIONS For histologic and cytologic evaluation of bone marrow hematopoietic cells, pelvis, proximal portion of the humerus, femur, and thickened portions of the peripheral cranial and caudal regions of the carapace and plastron are suitable sites to collect specimens. There are distinct cytochemical markers for heterophil, monocyte, and erythrocyte precursors, as well as later stage heterophils, eosinophils, basophils, monocytes, and azurophils.
Coil Design of 200 MVA/200 kV DC Superconducting Fault Current Limiter by Employing Iron Yoke

With increase of direct current (dc) transmission voltage and capacity, the short-circuit fault current of dc transmission is one of the serious difficulties in a high-power dc system. In order to reduce the fault current, we propose a coil design method of a 200 MVA/200 kV resistive dc superconducting fault current limiter (DC-SFCL). The target is to limit the short-circuit current to less than 1–35% of the predicted value when the dc short-circuit occurs. However, the cost of DC-SFCL in high-power dc system is relatively high, which weakens the advantage of resistive DC-SFCL. For economic reasons, a pair of iron yokes is installed with the DC-SFCL limiting component, a superconductor coil, to alter the magnetic field and promote the utilization efficiency of YBCO coated conductors. We design two resistive DC-SFCLs without and with iron yokes for comparison for target limiting resistance 5 Ω. Influence of the iron yoke is investigated and discussed in two-dimensional finite element method models by simulation. The simulation result shows that the proposed method is effective and economical.
Integrating Word Embedding based Cluster Features in Hindi Dependency Parsing

In this paper we present our efforts at incorporating word embedding cluster based features to aid data driven dependency parsing. This work is motivated by the observation that two words connected to a common head word through an identical dependency relation tend to be close to each other in the semantic space. We present a simple and effective semi-supervised method to introduce features that incorporate dependency label clusters derived from a large annotated corpus into data driven dependency parsing. We demonstrate the effectiveness of the approach in a series of experiments on the Hindi Dependency Treebank.
