Published: June 2016

Aims In this prospective observational study, we investigated the time-dependent changes and correlations of upper arm performance tests (ten-second test and Simple Test for Evaluating Hand Function (STEF), the Japanese Orthopaedic Association (JOA) score, and the JOA Cervical Myelopathy Evaluation Questionnaire (JOACMEQ) in 31 patients with cervical myelopathy who had undergone surgery. Patients and Methods We hypothesised that all the indices correlate with each other, but show slightly different recovery patterns, and that the newly described JOACMEQ is a sensitive outcome measure. Results Peak recoveries were achieved one month post-operatively in the ten-second test and JOACMEQ upper extremity function (UEF) subscale, and at three months in the JOA and STEF scores. The recoveries of all indices were maintained until six months post-operatively. The upper extremity function (UEF) subscale in the JOACMEQ showed the strongest correlation with STEF although all the indices correlated with each other. Patients with ≥ 20 and < 20 acquired points in the UEF subscale were classified into the UEF-improved and UEF-unimproved groups. Comparisons between the groups showed that pre-operative evaluation of “coordinated motion” of the STEF was significantly low in the UEF-unimproved group. Conclusion These results indicate that the JOACMEQ is a concise, sensitive, patient-based outcome measure for evaluating functional recovery in patients with cervical myelopathy who have undergone surgery.

Cementless total knee arthroplasty
Authors: Dalury D. F. 
Published: June 2016

As the number of younger and more active patients treated with total knee arthroplasty (TKA) continues to increase, consideration of better fixation as a means of improving implant longevity is required. Cemented TKA remains the reference standard with the largest body of evidence and the longest follow-up to support its use. However, cementless TKA, may offer the opportunity of a more bone-sparing procedure with long lasting biological fixation to the bone. We undertook a review of the literature examining advances of cementless TKA and the reported results.Cite this article: Bone Joint J 2016;98-B:867–73.

Aims This study describes the Osseointegration Group of Australia’s Accelerated Protocol two-stage strategy (OGAAP-1) for the osseointegrated reconstruction of amputated limbs. Patients and Methods We report clinical outcomes in 50 unilateral trans-femoral amputees with a mean age of 49.4 years (24 to 73), with a minimum one-year follow-up. Outcome measures included the Questionnaire for persons with a Trans-Femoral Amputation, the health assessment questionnaire Short-Form-36 Health Survey, the Amputation Mobility Predictor scores presented as K-levels, 6 Minute Walk Test and timed up and go tests. Adverse events included soft-tissue problems, infection, fractures and failure of the implant. Results Our results demonstrated statistically significant improvements in all five outcome measures. A total of 27 patients experienced adverse events but at the conclusion of the study, all 50 were walking on osseointegrated prostheses. Conclusion These results demonstrate that osseointegrated prostheses are a suitable alternative to socket-fit devices for amputees experiencing socket-related discomfort and that our strategy offers more rapid progress to walking than other similar protocols.

Aims The aims of our study were to provide long-term information on the behaviour of the thoracolumbar/lumbar (TL/L) curve after thoracic anterior correction and fusion (ASF) and to determine the impact of ASF on pulmonary function. Patients and Methods A total of 41 patients (four males, 37 females) with main thoracic (MT) adolescent idiopathic scoliosis (AIS) treated with ASF were included. Mean age at surgery was 15.2 years (11 to 27). Mean follow-up period was 13.5 years (10 to 18). Results For the TL/L curve, the mean curve flexibility evaluated with supine pre-operative bending radiographs was 78.6% (standard deviation 16.5%), with no significant loss of correction observed. On comparing patients with an increase of the TL/L curve increase (> 4º, n = 9, 22%) to those without, significant differences were observed in the correction rate of the MT curve at the final follow-up (p = 0.011), correction loss of the MT curve (p = 0.003) and the proportion of patients who had semi-rigid instrumentation (p = 0.003). Pre-operative percentage predicted forced vital capacity (%FVC) was 80%, dropping to 72% at final follow-up (p < 0.001). The Scoliosis Research Society questionnaire score was not significantly different between patients with and without a TL/L curve increase (p = 0.606). Spontaneous lumbar curve correction (SLCC) was maintained up to 18 years following selective ASF in most patients and demonstrated significant correlation with maintenance of MT curve correction. Conclusion Maintenance of MT curve correction using rigid instrumentation provided stable SLCC over time. An observed 8% decrease in %FVC indicates that ASF should be reserved for patients with no or only mild pulmonary impairment. Cite this article: Bone Joint J 2016;98-B:997–1002.

Authors: Zhu H-Y. , Gao Y-C. , Wang Y. , Zhang C-Q. 
Published: June 2016

Objectives Circulating exosomes represent novel biomarkers for multiple diseases. In this study, we investigated whether circulating exosome levels could be used as a diagnostic biomarker for steroid-induced osteonecrosis of the femoral head (ONFH). Methods We assessed the serum exosome level of 85 patients with steroid-induced ONFH and 115 healthy donors by Nanosight detection. We then assessed the diagnostic accuracy of serum exosomes by receiver operating characteristic curve analysis. Results The circulating exosome level of the ONFH group was significantly lower than that of control group. The area under the curve was 0.72, suggesting that the level of serum exosomes has moderate diagnostic accuracy for steroid-induced ONFH. Conclusion Circulating exosome levels are valuable in the diagnosis of steroid-induced ONFH. Cite this article: H-Y. Zhu, Y-C. Gao, Y. Wang, C-Q. Zhang.

Utopia, Palestine, and partition: Herbert Samuel’s An Unknown Land (1942)
Authors: Fordham Finn 
Published: July 2016

Abstract
This article examines the relation between, on the one hand, ‘An Unknown Land’, a moderately popular Utopian fiction written by the Jewish Liberal politician, Herbert Samuel, and, on the other, Samuel’s involvement in British policy towards Palestine from World War I to the time of the Arab Uprising (1936–1939). Samuel was the first High Commisioner of Palestine, from 1922 to 1925 under the British Mandate, and had sympathies with Zionism. In the late 1930s, he resisted (successfully) the various plans proposed to partition Palestine into Jewish, Muslim and specifically British areas. His resistance to partition, however, sits oddly alongside the fiction, in which the threat of sectarian civil war in Utopia is assuaged through a voluntary act of partition, agreed by all parties. The article argues that the contradiction does not signal any irony or satire against the condition of Utopia on Samuel’s part, but represents both a wish-fulfilment and Samuel’s Imperialist political unconscious in which Zionism is a means to an Imperialist end, and is justified as a Utopian triumph of modernity over tradition.

Authors: Kubieniec Joanna 
Published: June 2016

Abstract
In paper [4] there are considered random dynamical systems with randomly chosen jumps acting on Polish spaces. The intensity of this process is a constant λ. In this paper we formulate criteria for the existence of an invariant measure and asymptotic stability for these systems in the case when λ is not constant but a Lipschitz function.

Authors: Jomantienė Rasa , Ivanauskas Algirdas , Valiūnas Deividas , Urbanavičienė Laima , Šneideris Donatas 
Published: June 2016

Abstract
Here we report on a plant disease caused by insect-transmitted unculturable plant pathogenic bacteria detected in a private garden in Vilnius region. Samples of symptomatic peas (Pisum sativum L.), nasturtium (Tropaeolum majus L.), strawberry (Fragaria × ananassa Duchesne) and zucchini (Cucurbita pepo var. giromontina) plant tissues were collected. Based on the molecular technique, the Internet tools and phylogenetic analysis, these pathogens were identified as phytoplasmas and classified in phytoplasma RFLP (restriction fragment length polymorphism) group 16SrI, subgroup A. Because this pathogen may be spread by insect-vector that comes from the wild nature, the phytoplasmas could cause a problem in agriculture of Lithuania.
Vascular flora of the Viešvilė State Strict Nature Reserve and its buffer zone (West Lithuania)

Published: June 2016

Abstract
The paper presents analysis of the results of floristic studies carried out over 25 years in the Viešvilė State Strict Nature Reserve (VSSNR) and its buffer zone. The list of 703 vascular plant species including the data on their distribution and dynamics of abundance are provided. The native flora of the VSSNR includes 580 species, i.e. amounts to 47% of all native vascular plant species recorded in Lithuania. Since 1991, after the establishment of the Reserve, 15 species have become extinct and 30 have become endangered as a result of natural succession. Among 37 alien species recorded in the Reserve, four species are penetrating into natural habitats and threatening their existence. It was ascertained that about half of all species were recorded in meadows and glades of the forests, i.e. in the habitats, which occupy less than 1% of the whole territory. These are also habitats of most extinct and endangered species. Riparian and fontinal black alder woods are the most rich in vascular plant species among forest habitats.
Caldesia Parnassifolia – not extinct in Lithuania
Authors: Sinkevičienė Zofija 
Published: June 2016

Abstract

Caldesia parnassifolia (L.) Parl. is a “near threatened” species in Europe and it has been treated as extinct in Lithuania, the latest gathering dating back to 1957. Occurring there at the northern border of its range, this species was recorded only once at the beginning of the 19th century and twice in separate localities in the middle of the 20th century. In summer 2015, after an interval of almost 60 years, C. parnassifolia was found in a new locality, more than 100 km north of those previously known. A very abundant population composed of vegetative and flowering (turion forming) individuals was spread over about 3.5 ha area in Lake Rūžas, known as a unique Lithuanian habitat of Aldrovanda vesiculosa. C. parnassifolia formed almost monodominant stands along swampy shores and less abundantly occurred in communities of floating leaved species (mainly Nuphar luteum and Potamogeton natans) at a depth of 0.5–1 m. It is likely that implemented measures to improve the habitat condition for A. vesiculosa were favourable for the appearance of C. parnassifolia.
Effect of nano-silicon foliar application on safflower growth under organic and inorganic fertilizer regimes
Authors: Janmohammadi Mohsen , Amanzadeh Tahere , Sabaghnia Naser , Ion Viorel 
Published: June 2016

Abstract
Silicon nanoparticles have distinctive physicochemical characteristics and are able to enter into plants and impact the metabolism of plants as well as improve plant growth and yield under unfavourable environmental conditions. Besides, low soil organic matter content, imbalanced nutrient and inadequate water supply may adversely affect crop productivity in semiarid areas. To understand the effects of foliar spray of silicon dioxide nanoparticles (nSiO2) with application of farmyard manure (FYM) or inorganic fertilizer on morpho-physiological traits and yield of safflower, a field experiment was carried out in a highland semiarid region of Maragheh, northwest Iran. The experiment consisted of two levels of nSiO2 (0 and 20 mM) and four fertilizer regimes (control, 15 t ha−1 FYM, 30 t ha−1 FYM, 90 kg ha−1 N-P-K chemical fertilizer). Safflower plants were treated with nSiO2 suspension at leaf development, branching and capitulum emergence stages. Although the nSiO2 significantly improved some growth parameters such as canopy spread, stem diameter, plant height, ground cover and the number of achenes in capitulum, it did not affect achene yield and harvest index. However, fertilizer treatments considerably affected most of morpho-physiological traits, achene yield and yield components. The result showed that the best growth and the highest achene yield were achieved by application of 30 t ha−1 FYM before sowing. Application of high FYM increased the achene yield by 48% compared to the control, however, application of N-P-K chemical fertilizer or of 15 t ha−1 FYM improved achene yield only up to 17% over the no fertilizer condition. Moreover, this work revealed some positive effects of exogenous application of nSiO2 on safflower growth. This finding suggests that application of organic fertilizers with foliar spray of nSiO2 can improve safflower production and is an advisable agronomic option.

Published: June 2016

Abstract

Background:
The innovative pneumatic tube system (iPTS) transports one sample at a time without the use of cartridges and allows rapid sending of samples directly into the bulk loader of a laboratory automation system (LAS). We investigated effects of the iPTS on samples and turn-around time (TAT).

Methods:
During transport, a mini data logger recorded the accelerations in three dimensions and reported them in arbitrary area under the curve (AUC) units. In addition representative quantities of clinical chemistry, hematology and coagulation were measured and compared in 20 blood sample pairs transported by iPTS and courier.

Results:
Samples transported by iPTS were brought to the laboratory (300 m) within 30 s without adverse effects on the samples. The information retrieved from the data logger showed a median AUC of 7 and 310 arbitrary units for courier and iPTS transport, respectively. This is considerably below the reported limit for noticeable hemolysis of 500 arbitrary units.

Conclusions:
iPTS reduces TAT by reducing the hands-on time and a fast transport. No differences in the measurement results were found for any of the investigated 36 analytes between courier and iPTS transport. Based on these findings the iPTS was cleared for clinical use in our hospital.
Morphotectonic control of the Białka drainage basin (Central Carpathians): Insights from DEM and morphometric analysis.
Authors: Wołosiewicz Bartosz 
Published: June 2016

Abstract
The Białka river valley is directly related to a deep NNW-SSE oriented fault zone. According to the results of previous morphometric analyses, the Białka drainage basin is one of the most tectonically active zones in the Central Carpathians. It is also located within an area of high seismic activity.
In this study Digital Elevation Model (DEM) based, morphometric analyses were used to investigate the morphotectonic conditions of the watershed. The results reveal the relationships between the main tectonic feature and the landforms within the research area. The lineaments, as obtained from the classified aspect map, seem to coincide with the orientation of the main structures as well as the trends revealed by the theoretical Riedel-Skempton shear model. Base-level and isolong maps support the conclusion that the Białka and Biały Dunajec fault zones exert a strong influence on the morphology of the adjacent area.
The Idea of Enhancing Directional Energy Radiation by a Phased Antenna Array in UHF RFID System
Authors: Jankowski-Mihułowicz Piotr , Kawalec Damian , Węglarski Mariusz 
Published: June 2016

Abstract
The interrogation zone IZ is the most important parameter when RFID systems are considered. Its predictability is determined by the construction and parameters of antenna built in a read/write device. The IZ should be of sufficient size and appropriate to requirements established for an application of object automated identification. The method of shaping an antenna radiation pattern provides effective yet unconventional opportunities in this area. The idea and practical solution of the phased antenna array dedicated to UHF read/write devices are presented in the paper. On the basis of tests carried out, the authors pointed out the possibility of using developed devices for the synthesis of a determined IZ in anti-collision RFID system.
The Influence of Sintering Conditions on the Inkjet Printed Paths Resistance
Authors: Tomaszewski Grzegorz , Wałach Tadeusz , Potencki Jerzy , Pilecki Mariusz 
Published: June 2016

Abstract
The sintering of elements performed with the inkjet printing technique is one of the stages of flexible printed circuit manufacturing process. It is a crucial factor to determining the printed paths conductivity playing often an important role in the printed circuit. In this paper the study of the influence of thermal sintering conditions (temperature, time) on the resistance of paths made with inkjet printing on flexible substrates by using two electrically conductive inks was presented. The results of the investigations show that the sintering temperature is the main factor determining the paths resistance. Therefore, in some applications the sintering temperature higher than the one specified by the ink manufacturer can be used to decrease the paths resistance and to improve some circuit parameters. However, it should be noticed that the effective resistance decrease occurs only up to a certain temperature due to the appearance cracks in the printed paths.
An Energy Efficient QAM Modulation with Multidimensional Signal Constellation
Authors: Markiewicz Tomasz G. 
Published: June 2016

Abstract
Packing constellations points in higher dimensions, the concept of multidimensional modulation exploits the idea drawn from geometry for searching dense sphere packings in a given dimension, utilising it to minimise the average energy of the underlying constellations. The following work analyses the impact of spherical shaping of the constellations bound instead of the traditional, hyper-cubical bound. Balanced constellation schemes are obtained with the N-dimensional simplex merging algorithm. The performance of constellations of dimensions 2, 4 and 6 is compared to the performance of QAM modulations of equivalent throughputs in the sense of bits transmitted per complex (two-dimensional) symbols. The considered constellations give an approximately 0:7 dB to 1 dB gain in terms of BER over a standard QAM modulation.

Published: June 2016

Abstract
A class-D audio amplifier with analog volume control (AVC) for portable applications is proposed in this paper. The proposed class-D consist of two sections. First section is an analog volume control which consists of an integrator, an analog MUX and a programmable gain amplifier (PGA). The AVC is implemented with three analog inputs (Audio, Voice, FM). Second section is a driver which consists of a ramp generator, a comparator, a level shifter and a gate driver. The driver is designed to obtain a low distortion and a high efficiency. Designed with 0.18 um 1P6M CMOS technology, the class-D audio amplifier with AVC achieves a total root-mean-square (RMS) output power of 0.5W, a total harmonic distortion plus noise (THD+N) at the 8-Ω load less than 0.06% and a power efficiency of 90% with a total area of 1.74 mm2.
