New Geological, Palaeobotanical and Palynological Evidence of the Carboniferous from Brandov (Krušné Hory Mts., Czech Republic)
Authors: Šimůnek Zbyněk , Mlčoch Bedřich , Drábková Jana 
Published: August 2018

Abstract
Gas-pipeline construction around Brandov (Czech Republic) exposed pre Quaternary strata allowing more precise understanding of the regional geology. The crystalline rocks in the basement, near the Brandov Carboniferous Relict, belong to Sayda Dome rather than to the Hora Svaté Kateřiny (Katharinaberg) Dome. The lower Carboniferous unit (Westphalian – Moscovian) is of greater extent than previously estimated. In contrast, the upper unit, which is correlated with Stephanian (Kasimovian or Gzhelian) strata, is arealy less extensive than previously estimated and is devoid of fossil remains. An anthracite seam, in the lower unit, was discovered in the “North depth” some 1–1.3 km to the North from old mining activity of the “South depth”. The seam was accompanied by a flora dominated by cordaitaleans and sphenopsids (calamitaleans), and common lycopsids and ferns. Palynomorphs were isolated from mudstones for the first time and 36 genera and 51 species of miospores could be determined. A humic clayey layer was discovered in the Quaternary deposits whose palynological age is 500 – 100 years old.

Published: August 2018

Abstract
Histatins are histidine-rich peptides present in the saliva of humans and higher primates and have been implicated in the protection of the oral cavity. Histatin 1 is one of the most abundant histatins and recent reports show that it has a stimulating effect on cellular adherence, thereby suggesting a role in maintaining the quality of the epithelial barrier and stimulating mesenchymal-to-epithelial transition. Here we summarize these findings and discuss them in the context of previous reports. The recent findings also provide new insights in the physiological functions of histatin 1, which are discussed here. Furthermore, we put forward a possible role of histatin 1 in various pathologies and its potential function in clinical applications.

Published: August 2018

Abstract
The National Museum (NM) is preparing several temporary exhibitions in all of its buildings, along with preparing new permanent exhibitions in the New and Historical Buildings. All parts of the National Museum are incorporated in the preparation of new exhibitions, i.e. the Historical Museum, Natural History Museum, Czech Museum of Music, Náprstek Museum and the National Museum Library. In 2017, these exhibition projects are: Light and Life, Masaryk as a Phenomenon, and Indians. In 2018, the National Museum will present the Czech-Slovak / Slovak-Czech exhibition, which will reflect the 100th anniversary of the founding of Czechoslovakia, together with selected moments of Czechoslovakian history and the relationship of these two nations. 2019 could bring the opening of the grand Egyptology exposition Sun Kings and also new Natural history expositions. The remaining permanent expositions should be opened in 2020. The exhibitions in this period will likely recall some important anniversaries (1620, 1920). In future years, the renovation of the Czech Museum of Music and Náprstek Museum will take place.

In vitro antagonism of five rhizobacterial species against athelia rolfsii collar rot disease in soybean
Authors: Safni Irda , Antastia Widya 
Published: August 2018

Abstract
Plant Growth Promoting Rhizobacteria (PGPR) influence plant growth by a number of direct (producing plant growth promoting substances) and indirect (through prevention of deleterious effects of phytopathogenic microorganisms) mechanisms. Five species of bacteria were isolated from rhizospheric soils of soybean and peanut fields from several locations in North Sumatra. On the basis of morphological and biochemical characteristics, the bacteria were identified as Aeromonas hydrophila, Burkholderia cepacia, Serratia ficaria, Pantoea spp. 2, and Vibrio alginolyticus. These species were tested in vitro against the causal pathogen of collar rot disease of soybean, Athelia rolfsii, which is an important soybean disease in Indonesia. The five species of bacteria were subjected to screening of antagonistic activities against A. rolfsii in vitro with a dual culture-technique. Of the five species, B. cepacia, S. ficaria and V. alginolyticus were the most effective antagonistic bacteria to control A. rolfsii. B. cepacia, S. ficaria and V. algynolitycus produced inhibiting zones against A. rolfsii of 98.35%, 97.83% and 96.97% respectively. All bacterial species showed their antagonistic activity significantly with the inhibiting zone percentage being more than 60%. The experimental results suggested that all bacterial species have a future potency as a biocontrol agent to reduce A. rolfsii collar rot disease of soybean

Published: August 2018

Abstract
With the aging of the population worldwide, humanoid robots are being used with an older population, e.g., stroke patients and people with dementia. There is a growing body of knowledge on how people interact with robots, but limited information on the difference between young and old adults in their preferences when interacting with humanoid robots and what factors influence these preferences.We developed a gamified robotic platform of a cognitive-motor task.We conducted two experiments with the following aims: to test how age, location of touch interaction (touching the robot’s tablet or hand), and embodied presence of a humanoid robot affect the motivation of different age-group users to continue performing a cognitive-motor task. A total of 60 participants (30 old adults and 30 young adults) took part in two experiments with the humanoid Pepper robot (Softbank robotics). Both old and young adults reported they enjoyed the interaction with the robot as they found it engaging and fun, and preferred the embodied robot over the non-embodied computer screen. This study highlights that in order for the experience of the user to be positive a personalization of the interaction according to the age, the needs of the user, the characteristics, and the pace of the task is needed.
Evaluation of multiple transducers implementation in a magnetoelectric vibration energy harvester
Authors: Naifar Slim , Bradai Sonia , Viehweger Christian , Choura Slim , Kanoun Olfa 
Published: August 2018

AbstractA novel magnetoelectric (ME) vibration energy harvester employing magnetostrictive and piezoelectric laminate composite transducers is presented for potentially powering wireless sensor systems. The harvester consists of two four-layered Terfenol-D/PZT laminate composite and a magnetic circuit composed by two parallel magnetic springs and two rectangular magnets. The repulsive forces are realized by a magnetic spring for more robustness. In order to realize a high power density, a multiple transducer design with a lateral configuration is proposed. The magnetic flux density and the induced displacement in the magnetostrictive layers are investigated by finite element analysis to determine the optimal relative position of the twin transducers at the static equilibrium. Furthermore, the output characteristics of the harvester are experimentally studied and compared to the case when only a single transducer is used. The experimental results show that the twin lateral converter can provide a higher power outcome especially if operated at resonance. In addition, doubling the amplitude of vibration from 0.5 mm to 1 mm leads to a voltage output which is four times higher at resonance.

Abstract
In this paper, the plasma electrolytic oxidation (PEO) was used to improve the corrosion resistance of aluminum in 0.5 M HCl solution. Influence of many factors such as the composition of electrolytes, time and inorganic additives on the performance of PEO process have been investigated. The surface morphology of PEO films was inspected using SEM, EDX and XRD analysis. The electrochemical impedance spectroscopy (EIS) and polarization measurements were carried out to evaluate the corrosion resistance of aluminum. The hardness and reduced modulus of aluminum surface at different PEO process time were determined by nanoindenter measurements. The results showed that the best conditions for formation high efficient oxide layer on the aluminum surface during PEO process were carried out in 0.001 M NaOH electrolyte containing 9 × 10−5 M Na2WO4 for 5 min. The PEO process is able to inhibit uniform and pitting corrosion of aluminum in HCl solution. The surface morphology analysis showed that PEO process produce a highly resistant protective oxide layer, mainly composed of orthorhombic crystalline phase of α-Al2O3. This oxide characterized by its greater hardness.
A New Triaxial Apparatus Imposing Nonuniform Shearing for Deep Learning of Soil Behavior
Authors: Asmar Randa K. , Hashash Youssef M. A. 
Published: August 2018

Abstract
Soil behavior is commonly characterized based on laboratory tests with imposed or assumed uniform stress and strain distribution within a given soil specimen for convenient data reduction. This uniformity assumption limits the interpretation of each test to a single stress-strain path, and therefore, extensive laboratory testing is required to represent field soil behavior under a broad range of loading paths. This article presents the development of a modified, next-generation, triaxial device (NG-TX) to generate multiple loading paths in a single test that can be interpreted using an evolutionary deep-learning inverse analysis. This device inherits all features of a conventional triaxial test and adds lateral restraint clamps to increase nonuniformity in specimen deformation, combined with a digital photogrammetry system to measure the 3-D deformed shape of the specimen. The design of the restraint clamps was optimized using numerical simulations, which showed that the sheared specimen includes shear modes that cannot currently be mobilized with available testing devices. By coupling SelfSim, a deep-learning algorithm, with the modified triaxial device (NG-TX), the shear behavior of Ottawa sand was extracted. The SelfSim-extracted Neural Network material models were able to successfully capture the global behavior of each test and extract the nonuniform stress-strain behavior from within the specimens. The interpreted stress paths cover broad portions of stress space that current laboratory tests cannot cover. The stress-strain behavior is interpreted in terms of the mobilized secant friction angle using 2-D and 3-D failure criteria. The mobilized secant friction angle interpretation shows better agreement with empirically developed envelopes when computed along the octahedral plane accounting for the influence of intermediate principal stress.
Bending and Shear Stiffness of Cross-Laminated Timber Using a Variable Span Bending Test
Authors: Hindman Daniel P. , Bouldin John C. 
Published: August 2018

Abstract
Cross-laminated timber (CLT) is a novel wood product composed of lumber layers adhered orthogonally to create a two-way composite plate. The orthogonal orientation of the layers creates bending stiffness in both in-plane directions. However, compared to a solid wood beam, the orthogonal orientation of CLT reduces the shear stiffness in the longitudinal direction. Compared to a solid wood beam of the same material, shear deformation in CLT increases by approximately 30 %. Test methods to evaluate the shear stiffness terms of CLT beams are needed. This article examined two possible methods to obtain the bending and shear stiffness terms of CLT beams: (1) a simultaneous solution of the beam formulas currently tested in the product standard for CLT and (2) a regression method for variable span beams. Both methods produced similar bending and shear stiffness results. The use of a wide range of length-to-depth (L/d) ratios is recommended, with a minimum L/d value less than 10:1. Different loading configurations can be incorporated into the regression method provided that the regression terms are kept consistent. The simultaneous solution is of particular interest since no additional testing is needed beyond the current beam configurations in the CLT product standard.

Authors: Reid Laura J , Muthukrishnan Bala , Patel Dilip , Crane Mike S , Akyol Murat , Thomson Andrew , Seckl Jonathan R , Gibb Fraser W 
Published: August 2018

Objective
Primary hyperparathyroidism (PHPT) is a common reason for referral to endocrinology but the evidence base guiding assessment is limited. We evaluated the clinical presentation, assessment and subsequent management in PHPT.

Design
Retrospective cohort study.

Patients
PHPT assessed between 2006 and 2014 (n = 611) in a university hospital.

Measurements
Symptoms, clinical features, biochemistry, neck radiology and surgical outcomes.

Results
Fatigue (23.8%), polyuria (15.6%) and polydipsia (14.9%) were associated with PHPT biochemistry. Bone fracture was present in 16.4% but was not associated with biochemistry. A history of nephrolithiasis (10.0%) was associated only with younger age (P = 0.006) and male gender (P = 0.037). Thiazide diuretic discontinuation was not associated with any subsequent change in calcium (P = 0.514). Urine calcium creatinine clearance ratio (CCCR) was <0.01 in 18.2% of patients with confirmed PHPT. Older age (P < 0.001) and lower PTH (P = 0.043) were associated with failure to locate an adenoma on ultrasound (44.0% of scans). When an adenoma was identified on ultrasound the lateralisation was correct in 94.5%. Non-curative surgery occurred in 8.2% and was greater in those requiring more than one neck imaging modality (OR 2.42, P = 0.035).

Conclusions
Clinical features associated with PHPT are not strongly related to biochemistry. Thiazide cessation does not appear to attenuate hypercalcaemia. PHPT remains the likeliest diagnosis in the presence of low CCCR. Ultrasound is highly discriminant when an adenoma is identified but surgical failure is more likely when more than one imaging modality is required.
Non-functional duodenal neuroendocrine carcinoma: a rare cause of diabetes mellitus
Authors: Bisambar Chad , Collier Andrew , Duthie Fraser , Meney Carron 
Published: August 2018

Summary
A 40-year-old Caucasian female presented with hyperglycaemia, polyuria, polydipsia and weight loss of 6 kg over a 1-month period. There was no personal or family history of malignancy or diabetes mellitus. On examination, she was jaundiced with pale mucous membranes and capillary glucose was 23.1 mmol/L. Initial investigations showed iron deficiency anaemia and obstructive pattern of liver function tests. HbA1c was diagnostic of diabetes mellitus at 79 mmol/mol. Malignancy was suspected and CT chest, abdomen and pelvis showed significant dilatation of intra- and extra-hepatic biliary tree including pancreatic duct, with periampullary 30 mm mass lesion projecting into lumen of duodenum. Enlarged nodes were seen around the superior mesenteric artery. This was confirmed on MRI liver. Fasting gut hormones were normal except for a mildly elevated somatostatin level. Chromogranin A was elevated at 78 pmol/L with normal chromogranin B. Duodenoscopy and biopsy showed possible tubovillous adenoma with low-grade dysplasia, but subsequent endoscopic ultrasound and biopsy revealed a grade 1, well differentiated neuroendocrine tumour. The patient was started on insulin, transfused to Hb >8 g/dL and Whipple’s pancreatico-duodenectomy was undertaken. This showed a well-differentiated neuroendocrine carcinoma arising in duodenum (Grade G1 with Ki67: 0.5%), with areas of chronic pancreatitis and preservation of pancreatic islet cells. There was complete resolution of diabetes post Whipple’s procedure and patient was able to come of insulin treatment. Her last HBA1C was 31 mmol/mol, 4 months post tumour resection.

Learning points:

Diabetes mellitus and malignancy can be related.

A high index of suspicion is needed when diabetes mellitus presents atypically.

Non-functional neuroendocrine tumours can present with diabetes mellitus.
My tummy hurts – a case report of abdominal pain and macrocytic anemia caused by hypothyroidism
Authors: Hamid Kewan , Dayalani Neha , Jabbar Muhammad , Saah Elna 
Published: August 2018

Summary
A 6-year-old female presented with chronic intermittent abdominal pain for 1 year. She underwent extensive investigation, imaging and invasive procedures with multiple emergency room visits. It caused a significant distress to the patient and the family with multiple missing days at school in addition to financial burden and emotional stress the child endured. When clinical picture was combined with laboratory finding of macrocytic anemia, a diagnosis of hypothyroidism was made. Although chronic abdominal pain in pediatric population is usually due to functional causes such as irritable bowel syndrome, abdominal migraine and functional abdominal pain. Hypothyroidism can have unusual presentation including abdominal pain. The literature on abdominal pain as the main presentation of thyroid disorder is limited. Pediatricians should exclude hypothyroidism in a patient who presents with chronic abdominal pain. Contrast to its treatment, clinical presentation of hypothyroidism can be diverse and challenging, leading to a delay in diagnosis and causing significant morbidity.

Learning points:

Hypothyroidism can have a wide range of clinical presentations that are often nonspecific, which can cause difficulty in diagnosis.

In pediatric patients presenting with chronic abdominal pain as only symptom, hypothyroidism should be considered by the pediatricians and ruled out.

In pediatric population, treatment of hypothyroidism varies depending on patients’ weight and age.

Delay in diagnosis of hypothyroidism can cause significant morbidity and distress in pediatrics population.
Growth hormone deficiency as a cause for short stature in Wiedemann–Steiner Syndrome
Authors: Stoyle George , Banka Siddharth , Langley Claire , Jones Elizabeth A , Banerjee Indraneel 
Published: August 2018

Summary
Wiedemann–Steiner Syndrome (WSS) is a rare condition characterised by short stature, hypertrichosis of the elbow, intellectual disability and characteristic facial dysmorphism due to heterozygous loss of function mutations in KMT2A, a gene encoding a histone 3 lysine 4 methyltransferase. Children with WSS are often short and until recently, it had been assumed that short stature is an intrinsic part of the syndrome. GHD has recently been reported as part of the phenotypic spectrum of WSS. We describe the case of an 8-year-old boy with a novel heterozygous variant in KMT2A and features consistent with a diagnosis of WSS who also had growth hormone deficiency (GHD). GHD was diagnosed on dynamic function testing for growth hormone (GH) secretion, low insulin-like growth factor I (IGF-I) levels and pituitary-specific MRI demonstrating anterior pituitary hypoplasia and an ectopic posterior pituitary. Treatment with GH improved height performance with growth trajectory being normalised to the parental height range. Our case highlights the need for GH testing in children with WSS and short stature as treatment with GH improves growth trajectory.

Learning points:

Growth hormone deficiency might be part of the phenotypic spectrum of Wiedemann–Steiner Syndrome (WSS).

Investigation of pituitary function should be undertaken in children with WSS and short stature. A pituitary MR scan should be considered if there is biochemical evidence of growth hormone deficiency (GHD).

Recombinant human growth hormone treatment should be considered for treatment of GHD.
Вплив засобів масової комунікації на природні, біологічні та соціально- психологічні чинники в процесі трудової адаптації

У сучасний час засоби масової комунікації грають значну роль у формуванні уявлення соціуму про навколишній світ та безпосередньо впливають на поведінку окремих груп у повсякденній діяльності.У сучасний час засоби масової комунікації грають значну роль у формуванні уявлення соціуму про навколишній світ та безпосередньо впливають на поведінку окремих груп у повсякденній діяльності.Труд є одним із основних видів діяльності людини в процесі життя, тому питання поведінки індивідів та груп під час трудового процесу та самого відношення до праці, починаючи з ХІХ століття по сучасний час, є об’єктом уваги багатьох вітчизняних та іноземних дослідників. Важливими віхами в сучасній соціології праці є роботи М. П. Лукашевича, А. С. Лобанової, Г. В. Дворецької.Одним із питань процесу трудової діяльності є процес адаптації індивідів та гру до нових умов праці, а також детермінанти відповідних адаптаційних процесів.У статті досліджено різноманітні прояви впливів засобів масової комунікації на природні, біологічні та соціально-психологічні чинники в процесі трудової адаптації. З’ясовано, що вплив ЗМК на дію природних чинників може призвести до ефектів двох видів: викривлення уявлення суб’єктів трудової адаптації про реальні впливи природних (космічних) сил на умови трудової діяльності за певною професією, неадекватне уявлення суб’єктами трудової адаптації власних можливостей у взаємодії з природними умовами трудової діяльності. Підтверджено гіпотезу про вплив ЗМК на чинники, що зумовлюють адаптаційні процеси.
