Core Ideas
Feijoa fruit combine unique flavor and medicinal properties.
The Brazilian feijoa collection exhibit high variability in fruit traits.
Years was the major effect to all fruit trait phenotype in south of Brazil.
The aim of the present work was to physicochemically characterize the fruits of accessions of feijoa [Acca sellowiana (O. Berg.) Burret] active germplasm bank (BAG), located in São Joaquim, Brazil. The identification of accessions with desirable fruit traits will facilitate species breeding and cultivation. During seven harvests (2004–2017), 10 fruits per plant of 229 accessions were evaluated for fruit diameter, length and weight, skin and pulp weight, skin thickness, pH, titratable acidity, and soluble solids content, in addition to the qualitative descriptors insertion of sepals, fruit shape, sheen of skin, vacuum, color of skin and pulp, and texture and roughness of the skin. Descriptive statistics, correlations, and a multivariate analysis were applied to better understand the nature and magnitude of the variables. The mean +1SD was used to identify the best accessions for breeding purposes. Active germplasm bank accessions revealed significant phenotypic diversity for the physicochemical characteristics of the fruits, and the year effect represented the largest contribution to the variance for all evaluated characteristics, except fruit length. The characteristics total fruit weight, fruit diameter, and skin thickness are strongly related to pulp yield (%). There is high phenotypic diversity in accessions of feijoa conserved in the São Joaquim BAG, which will allow different traits of this species to be genetically improved.

Published: March 2019

A Biologia se constituiu como uma ciência do conhecimento, passando por períodos de descrédito nos quais não era considerada uma ciência segmentada em várias áreas de mesmo nível de reconhecimento da Física e a Química. Tais contextos acabaram influenciando a construção da disciplina Biologia, que se caracteriza como fragmentada, descritiva e memorística. A presente pesquisa, de natureza qualitativa, buscou investigar as concepções acerca da epistemologia da Biologia elucidadas por participantes de uma Comunidade de Prática, constituída por professores pesquisadores, pós-graduandos, graduandos e professores da educação básica. Os discursos dos sujeitos da pesquisa foram obtidos por meio de gravações das reuniões referentes aos temas da epistemologia da ciência, posteriormente transcritos e tratados com o auxílio da Análise Textual Discursiva. O tratamento dos dados pela ATD possibilitou a emergência de duas categorias, Biologia ou Ciências Biológicas, Biologia: construção histórica e autonomia, que possibilitaram a construção de um metatexto sobre a natureza da Ciência Biologia. Na visão dos participantes, a Biologia se caracteriza como uma ciência autônoma no presente momento, porém ainda não se encontra completamente unificada.

EDXRF Spectrometry and Complementary Non-Destructive Analytical Techniques in the Archaeometric Study of Copper Artefacts
Authors: S. Katsifas Christos , A. Zachariadis George 
Published: March 2019

Background:For more than a decade, Energy Dispersive X-Ray Fluorescence (EDXRF) spectrometry is the primary analytical technique in archaeometric research and especially in the study of ancient copper artefacts. EDXRF has established itself as the fundamental archaeometric analytical technique because of features like: the ability to analyze samples in a non destructive or non invasive way, no requirements for sample preparation, portability, in situ analysis, simultaneous determination of many elements and finally its easy in use. At the same time there is an explosion of related research publications which provide new possibilities to museums and archaeology scientists. On the other hand, due to its limitations it cannot provide information for every analytical question.Objective:The goal of this article is to present an overview of the capabilities of the contemporary EDXRF spectrometry for the study of ancient copper artifacts and the necessity to be implemented, depending on the analytical question, in correlation with complementary analytical techniques which are presented through related case studies.Conclusion:The demand for studying artefacts in situ, the evolution of the instrumentation and the access of more scientists (historians, archaeologists, curators etc.) to archaeometry will maintain EDXRF spectrometry as the central analytical technique. Limitations like inability for light elements detection, penetration depth, low (relatively) sensitivity can be partially overcome with the implementation of other analytical techniques which will provide complementary information. Moreover, progress in non-invasive analysis and new portable instruments combining elemental and molecular techniques expand significantly the capabilities of in situ analysis.
Random Black Hole Attack Modelling and Mitigation Using Trust- Confidence Aware OLSR in MANETs for Private Data Communications
Authors: Adoni Kirti A. , S. Tavildar Anil , K. Warhade Krishna 
Published: March 2019

Background and Objective:
Random Black Hole (BH) attack significantly degrades MANET’s
performance. For strategic applications, the performance parameters like Packet Delivery Ratio,
Routing Overheads, etc. are important. The objectives are: (a) To model random BH attack, (b)
To propose a routing strategy for the protocol to mitigate random BH attack, (c) To evaluate and
compare the network performance of modified protocol with the standard protocol.

Methods:
The random BH attack is modelled probabilistically. The analysis is carried out by varying
Black Hole Attack (BHA) time as Early, Median, Late occurrences and mix of these three categories.
The blocking performance is also analysed by varying the percentages of malicious presence in the
network. Normal Optimized Link State Routing (OLSR) protocol is used to simulate the MANET
performance using a typical medium size network. The protocol has then been modified using Trust-
Confidence aware routing strategy, named as TCAOLSR, with a view to combat the degradations
due to the random BH attack.

Results:
The random behavior of Black Hole attack is analyzed with all the possible random parameters,
like deployment of mobile nodes, number of malicious nodes and timing instances at which these
nodes change their state. From the results of individual type- Early, Median and Late, it is observed
that the TCAOLSR protocol gives stable performance for Packet Delivery Ratio (PDR) and
Routing Overheads (RO), whereas for OLSR protocol PDR gradually reduces and RO increases. For
individual and mix type, Average Energy Consumption (AEC) per node increases marginally for
TCAOLSR protocol. For the mix type, PDR for TCAOLSR is 40-60% better whereas RO for
TCAOLSR is very less compared to OLSR protocol. The efficacy of the TCAOLSR protocol remains
stable for different categories of BH attack with various percentages of malicious nodes compared
to OLSR with the same environment.

Conclusion:
Simulations reveal that the modified protocol TCAOLSR, effectively mitigates the network
degradation for Packet Delivery Ratio and Routing Overheads considerably, at the cost of a slight increase
in Average Energy Consumption per node of the network. Efficacy of the OLSR and TCAOLSR
protocols has also been defined and compared to prove robustness of the TCAOLSR protocol.

Perencanaan Perencanaan produksi merupakan suatu kegiatan yang harus dilakukan sebelum proses produksi dimulai. Perencanaan produksi tidak hanya menyangkut mengenai apa yang diproduksi, melainkan ada beberapa hal yang harus dilakukan. Salah satunya merencanakan kebutuhan bahan untuk produksi. PT. X merupakan perusahaan yang bergerak pada bidang aksesoris otomotif. Dalam proses produksinya, PT. X mengalami kesulitan dalam pengendalian stok bahan baku karena stok bahan yang berlebih. Pemesanan kepada pemasok dilakukan tanpa adanya analisa yang akurat. Untuk itu PT. X memerlukan metode analisa penghitungan kebutuhan bahan sebelum proses produksi dimulai. metode yang dilakukan yaitu MRP (material requirement planning). Penelitian ini dilakukan dengan menentukan Jadwal Induk Produksi (JIP). Kemudian menentukan struktur produk stok bahan baku yang diperlukan untuk membuat satu produk jadi. Melakukan konversi dari jumlah Jadwal Induk Produksi (JIP) menjadi “kebutuhan bersih”. Selanjutnya membandingkan kebutuhan yang ada dengan jumlah stok yang ada. Dan menghasilkan informasi mengenai kapan dan berapa jumlah stok bahan yang harus dipesan kepada pemasok. Untuk mempermudah penghitungan, maka dibuat aplikasi berbasis web yang memiliki fungsi dalam melakukan peramalan stok dengan metode MRP. Hasil dari aplikasi MRP pada PT.X adalah menurunnya jumlah stok bahan di gudang mencapai 50%.

Published: March 2019

ABSTRACT

Objectives:
To evaluate the precision of the virtual occlusal record using the Carestream CS3600 Intraoral Scanner (Carestream Dental, Atlanta, Ga).

Materials and Methods:
A total of 20 participants were recruited for this prospective study using preestablished inclusion/exclusion criteria. A complete intraoral scan and two bite registrations were obtained. The participants were instructed to bite with normal pressure when bite registrations were acquired. Contact locations, size (circumference), and intensity were identified on the maxillary first molars and canines. Agreement between contact size and intensity was assessed with intraclass correlation coefficients. Kappa statistics evaluated agreement in contact locations. Statistical significance was set at P &lt; .05.

Results:
All participant data were included for statistical analysis. Between the two bite registrations, nonstatistically significant differences were observed in the proportion of locations with contacts (P = .7681). A nonstatistically significant difference (−0.25 mm, P = .8416) in mean contact circumference size was observed. A statistically significant difference in mean contact intensity was observed (P = .0448). When evaluating agreement between the bite registrations, a weak correlation for size (intraclass correlation coefficient = 0.35) and intensity (intraclass correlation coefficient = 0.32) was observed as well as a moderate agreement for contact location (κ coefficient = 0.67).

Conclusions:
The findings suggest that the Carestream intraoral scanner software possesses adequate precision when acquiring the location and size of the contacts in bite registrations. The scanner failed to demonstrate adequate precision when acquiring contact intensities in bite registrations. Additional research is warranted to further investigate the precision of virtual occlusal records with currently available software systems.

Biomechanical comparison of a modified three-loop pulley technique and a three-level self-locking technique for repair of patellar tendon rupture in dogs
Authors: Soula Mariajesus , Shmalberg Justin W. , Johnson Matthew D. 
Published: March 2019

Abstract

OBJECTIVE
To compare use of a 3-level self-locking suture (3LSLS) technique with use of a previously described modified 3-loop pulley (M3LP) technique to repair rupture of the proximal aspect of patellar tendons in limbs from canine cadavers.

SAMPLE
Paired hind limbs of 6 adult mixed-breed dogs.

PROCEDURES
A limb from each pair was randomly assigned to be repaired by the 3LSLS technique or M3LP technique with size-2 ultrahigh-molecular-weight polyethylene and size-0 monofilament polypropylene suture, respectively. Limbs were prepared, and each patellar tendon was transected at a site chosen to simulate rupture at the proximal aspect. Tendons were repaired with the assigned techniques and mechanically tested with a biaxial servohydraulic test system; the clamp was distracted until the repair failed. Force at 1 -mm gap formation, 3-mm gap formation, and repair failure and gap size at failure were measured and compared between methods. Mode of failure was recorded.

RESULTS
There was no significant difference between methods for the force required to produce a 1 - or 3-mm gap in the repair. The 3LSLS technique required a significantly higher load for complete failure; gap formation immediately before failure was significantly greater for this method than for the M3LP technique. Four of 6 repairs with the M3LP technique and 0 of 6 repairs with the 3LSLS technique failed by suture breakage.

CONCLUSIONS AND CLINICAL RELEVANCE
The 3LSLS technique with size-2 ultrahigh-molecular-weight polyethylene suture was as effective at resistance to 1 - and 3-mm gap formation as the M3LP with size-0 monofilament polypropylene suture.
Single-day and multiday repeatability of stance analysis results for dogs with hind limb lameness
Authors: Wilson Megan L. , Roush James K. , Renberg Walter C. 
Published: March 2019

Abstract

OBJECTIVE
To assess single-day and multiday repeatability of weight distribution (stance) data obtained with a commercial analyzer for dogs with naturally occurring hind limb lameness.

ANIMALS
46 dogs (15 and 31 for single-day and multiday trials, respectively).

PROCEDURES
For single-day trials, 5 to 10 measurements/trial were collected to determine body weight (BW), weight distribution on each limb, and forelimb and hind limb symmetry indices (SIs). The dog was removed from the room and returned immediately; 5 trials were performed. For multiday trials, measurements were performed in the same manner on 2 sequential days. Data were compared among trials (single-day measurements) and between days (multiday measurements). Repeatability (correlation coefficients and Lin concordance correlation coefficients [LCCCs]) and variability (coefficients of variation [CVs]) were assessed.

RESULTS
In single-day trials, BW (r = 0.999), weight distribution on the lame hind limb (r = 0.915) and contralateral hind limb (r = 0.948), and hind limb SI (r = 0.964) were each significantly correlated among trials. In multiday trials, BW results were similar; weight distribution on the lame hind limb and contralateral hind limb and hind limb SI were each less closely but still significantly correlated between days. The LCCCs were highest for BW, weight distribution on the contralateral hind limb, and hind limb SI in single-day trials and for BW and weight bearing on the contralateral and lame hind limbs in multiday trials. The CVs were lowest for BW and highest for forelimb SI in both trial types.

CONCLUSIONS AND CLINICAL RELEVANCE
The analyzer used allowed repeatable measurement of BW and weight distribution on the hind limbs of dogs with hind limb lameness. Measurement of forelimb stance variables was not repeatable in this group of dogs.
The impact of cattle drinking points on aquatic macroinvertebrates in streams in south-east Ireland
Authors: Madden D. , Harrison S. , Finn J.A. , hUallacháin D. Ó 
Published: March 2019

Abstract
Measures that prevent cattle access to watercourses are commonly implemented through agri-environment schemes, in an effort to address the objectives of the Water Framework Directive. Despite the widespread implementation, few studies have assessed the impact of cattle access to streams on aquatic macroinvertebrates. This study assessed the local-scale impact of cattle drinking points on water quality parameters (i.e. macroinvertebrate and water chemistry metrics) on 39 intensively-managed grassland farms in the south-east of Ireland. The results indicate that sites that were more than or equal to good quality upstream of cattle drinking points, were more susceptible to cattle access impacts than sites where upstream water quality was less than good. The European Court of Auditors (2011) recommended that there should be a higher rate of EU contribution for measures with higher environmental potential, in this instance, for cattle exclusion measures targeted to sites where background quality is more than or equal to good. Appropriate efforts should thus be made to incentivise farmers in good to high status sites to adopt cattle exclusion measures.
