DESIGN OF A BEAM SWITCHTABLE SUPERDIRECTIVE DIPOLE FOR IOT GATEWAY

—In this paper, a switchable beam and super-directive Electrically Small Antenna (ESA) dipole deployed at an IoT network gateway at 868 MHz is presented. It consists of one fed dipole and one loaded parasitic dipole. The nature and value of the load are obtained using the Uzkov equations, allowing determining current weighting coeﬃcients in the case of two separately fed antennas, in order to maximize the gain and the directivity in a given direction. Reconﬁgurability in two directions is achieved using a pair of anti-parallel PIN diodes to steer the beam to the desired direction. The array ﬁnal dimensions are 109 × 43 mm 2 (0 . 3 λ × 0 . 1 λ ) generating a high directivity of 6.8 dBi in simulation and 6.7 dBi in measurement at 868 MHz for each beam in the azimuth plane.
ENZYME SUPPLEMENTATION TO CORN AND SOYBEAN MEAL DIETS

SUMMARY Energy and protein nutrient specifications in broiler rations in the United States are primarily met with corn and soybean meal, respectively. Little has been done to improve the nutrient availability of corn or soybean meal because they are considered to be highly digestible. However, the energy availability of the carbohydrate portion of soybean meal in poultry is low. Research has indicated that dietary α-galactosidase improves the energy availability of soybean meal. We conducted this research to determine whether a dietary enzyme preparation containing αgalactosidase would improve growth performance or carcass attributes of broilers fed corn and soybean meal diets. Three thousand six hundred straight-run commercial broilers were fed diets with or without an enzyme preparation primarily containing α-galactosidase during periods of hot temperature conditions. Broilers in the enzyme-supplemented treatment had significantly reduced 1- to 49-d feed conversion and mortality. A subsequent battery chick trial showed no beneficial effects of the enzyme on growth performance of male chicks. Commercial broilers reared in hot temperature conditions that received corn- and soybean meal-based diets supplemented with α-galactosidase might have improved performance.
Phylogeny, historical biogeography, and macroevolution of host use among Diastrophus gall wasps (Hymenoptera: Cynipidae)

Phylogenetic relationships among 14 species of 3 Holarctic gall wasp genera, Diastrophus Hartig, Gonaspis Ashmead, and Xestophanes Forster (Hymenoptera: Cynipidae: Cynipinae: Aylacini), are inferred from 43 adult morphological characters. The incorporation of four characters associated with gall morphology is explored, although only a single parsimony-informative gall character is obtained. All analyses retrieve Diastrophus as paraphyletic with respect to the monotypic genus Gonaspis. These two genera share several morphological synapomorphies as well as related host plant associations. The genus Gonaspis is thus a new junior synonym of Diastrophus, and Gonaspis potentillae is herein transferred to Diastrophus as D. potentillae Bassett. In addition, D. kincaidii var. austrior Kinsey is formally elevated to specific status, as Diastrophus austrior Kinsey (new status). Association of Diastrophus species with Rubus, as well as with woody host plants, could have originated once, but the possibility of more than one origination cannot be excluded. In either case, at least two reversal events have contributed to the patterns of association of Diastrophus with Potentilla, and with herbaceous host plants. Reconstruction of the historical biogeography of the group using a dispersal and vicariance analysis model suggests that the ancestor of Diastrophus was either East Nearctic (EN) or Holarctic. The two West Palearctic (WP) species resulted from either two independent dispersals from EN followed by subsequent vicariance, or from a basal vicariance between WP and EN and a subsequent dispersal from EN to WP followed by a subsequent vicariance between the two regions. The West Nearctic species resulted from dispersals from EN and are relatively recent.
COMPUTER ANALYSIS OF DISEASE DATA TO DERIVE HYPOTHETICAL GENOTYPES FOR REACTION OF HOST VARIETIES TO PATHOGENS

A method is described for deriving genotypes for low reaction in varieties of a host from data resulting from inoculating many host varieties with many cultures of a pathogen. A computer program utilizing Boolean algebra was used to compare and group patterns of low and high infection types produced by host variety: pathogen culture combinations. Visual inspection within each group allows derivation of the genotype. A successful trial of the system was made with data on wheat leaf rust involving 60 varieties of wheat and nine cultures of Puccinia recondita.

Genetic studies on internal and external egg quality traits of Guinea fowl

The four hundred sixty two eggs of 38 weeks old Guinea fowl, produced from 23 sires and 120 dams were used. The average value of egg weight, egg length, egg width, shape index, yolk weight, yolk height, yolk width, yolk index, albumen weight, albumen height, albumen width, albumin volume, albumen index, shell weight, shell thickness and haugh unit were found as 39.24±0.15 g, 4.90±0.11 mm, 3.82±0.007 mm, 77.83±0.26, 12.09±0.049 g, 16.40±0.046 mm, 37.7±0.18 mm, 0.44±0.01, 21.50±0.086 g, 6.42±0.045 mm, 63.0±0.25 mm, 21.13±0.079 ml, 0.103±0.001, 5.74±0.044 g, 0.38±0.003 mm and 86.36±0.289 per cent, respectively. The heritability estimates, based on sire component of variance for corresponding traits were 0.43±0.05, 0.29±0.04, 0.31±0.01, 0.16±0.05, 0.25±0.07, 0.49±0.06, 0.22±0.08, 0.18±0.01, 0.46±0.08, 0.27±0.06, 0.11±0.04, 0.12±0.03, 0.14±0.08, 0.09±0.02, 0.15±0.06 and 0.26±0.11, respectively. Guinea fowl has got more yolk weight, shell weight over commercial chicken indicating the availability of more nutrients per egg and less chances of egg breakage during transportation. Sufficient variability observed in most of the egg quality traits indicated the scope of further genetic improvement.
The Handling of Business Lawsuits by Common Courts in Poland: Identification of Transaction Costs

The aim of the article is to identify factors influencing the transaction costs of the enforcement of contracts concluded between entrepreneurs in business matters. For the purpose of the article, a pilot study was conducted involving 210 court cases pending before the District Court in Gdańsk in the first instance after 2009, in which the judgment was issued in 2012 (the last 210 cases) and for which the appeal was lodged to the Appeals Court in Gdańsk and the proceedings were concluded before 2013. The conducted case study was to identify factors influencing the transaction costs of contractual rights on the supply side, i.e. as part of court activity. Transaction costs of contract enforcement include not only the costs of court fees and legal representation, which are defined normatively, but also – and what is obvious – the time necessary to exercise rights under the contract. The study attempted to answer two research questions. First, which factors influence the time of consideration of the case, from the moment it reaches the court of first instance up to the second-instance judgment, and second – to what extent the level of complexity of the case is correlated with the time of its examination. The results enabled preselecting the basic factors that identify the level of complexity of the case. It was assumed in this article that they include: the number of volumes accumulated throughout the examination of the case, the number of hearings, and the number of pages of justification of the first- and second-instance judgment.
The life table of Cryptolaemus montrouzieri Mulsant (Coleoptera: Coccinellidae) after different storage periods

The life table of Cryptolaemus montrouzieri Mulsant (Coleoptera: Coccinellidae) was calculated on Planococcus citri (Risso) (Homoptera: Coccidae) under laboratory conditions at 25±1°C and 45±5% relative humidity after different storage periods at 15°C of cooling. Experiments consisted of 5 groups including a control and design experiments that were run for 5, 10, 15 and 20 days, respectively. The following predictive parameters were obtained for the control and design experiments: intrinsic rate of increase r m = 0.098, 0.092, 0.074, 0.058 and 0.045; net reproductive rate R 0 = 340.703, 276.629, 149.930, 119.321 and 65.928; mean generation time T 0 = 59.350, 60.851, 67.726, 83.189 and 94.173, respectively. Doubling time DT= 7.2, 7.9, 9.3, 12.1 and 15.3, and finite rate of increment λ = 1.101, 1.092, 1.074, 1.059 and 1.046, were calculated as well. The reproductive value (V x ) for each group was plotted.
Effects of atmospheric carbon dioxide fertilization on biomass and secondary metabolites of some plant species with pharmacological interest under greenhouse conditions

The increase of atmospheric CO 2 due to global change and/or horticultural practices promotes direct effects on plant growth and development. These responses may occur in natural ecosystems, but also can be used to increase the production of some plants and some secondary compounds. Present work tries to study the effects of atmospheric CO 2 enrichment under greenhouse conditions on growth and in the concentration and composition of secondary metabolites of Taxus bacatta, Hypericum perforatum and Echinacea purpurea under Mediterranean environmental conditions. CO 2 fertilization shows interesting perspectives to increase and improve horticultural techniques in order to increase plant medicinal productivity, in spite of clear differences among the species. In general this technique promotes important and significant increases in primary productivity and, in some cases, also in secondary compounds. This has a great horticultural relevance because the total productivity of this kind of products increase at crop level, directly because concentration is increased and /or indirectly because biomass is increased.
Localization of T- and B-Iymphocytes in the lymphoid organs of chicken embryo and assessment of their functional status

Present study was conducted to investigate the localization of two important components of humoral and cell mediated immunity, i.e. T- and B-lymphocytes and assessment of their functional status in developing chicken embryo using monoclonal markers and immunoperoxidase staining technique. T-cells were demonstrated in thymic cortex and B-cells in bursal follicles. In spleen T-cells were found around the arterial blood vessels with B-cell colonies in between. Both T- and B-cells were not responsive to mitogenic stimuli at 16th day of incubation, but their response was very high at 21st day of incubation. This showed that however, lymphocytes are differentiated into T- and B-lymphocytes at 16th day of incubation, but they start functioning at 21st day of incubation.

Effects of Exogenous Phytase on Growth Performance of Weaned Dorper x Pelibuey Lambs

The objective of this study was to evaluate the effect of an exogenous phytase on in vitro residual phosphorus (P) concentration and performance of 30 weaned ¾ Dorper vs ¼ Pelibuey lambs (12.12±1.46 kg BW). In vitro treatments were: 0 and 0.12 mg phytase per g of sorghum, corn gluten meal (CGM), alfalfa hay and experimental diet (70% ground sorghum grain, 16.9% CGM, 12% alfalfa hay, 1.1% calcium carbonate). There were significant (P 0.05) ADG (251, 294 and 266 g/d), DMI (905, 1119 and 975 g/d), FC (4.06, 4.37 and 3.94). However, phytase addition increased DMD (72.34, 82.54 and 82.57%) and FPE (1.01, 1.09 and 1.26 g/d). It may be concluded that apparent DM digestibility as well as faecal excretion of phosphorus were affected when an exogenous phytase was added to a 70% sorghum grain diet, fed to weaned Dorper x Pelibuey lambs.
Artificial Intelligence in Innovation: How to Spot Emerging Trends and Technologies

Firms apply strategic foresight in technology and innovation management to detect discontinuous changes early, to assess their expected consequences, and to develop a future course of action enabling superior company performance. For this purpose, an ever-increasing amount of data has to be collected, analyzed, and interpreted. Still, a major part of these activities is performed manually, which requires high investments in various resources. To support these processes more efficiently, this article presents an artificial-intelligence-based data mining model that helps firms spot emerging topics and trends at a higher level of automation than before. Its modular structure consists of components for query generation, data collection, data preprocessing, topic modeling, topic analysis, and visualization, combined in such a way that only a minimum amount of manual effort is required during its initial set up. The approach also incorporates self-adaptive capabilities, allowing the model to automatically update itself once new data has become available. The model parameterization is based on latest research in this area, and its threshold parameter is learnt during supervised training using a training data set. We have applied our model to an independent test data set to verify its effectiveness as an early warning system. By means of a retrospective analysis, we show in three case studies that our model is able to identify emerging technologies prior to their first publication in the Gartner Hype Cycle for Emerging Technologies. Based on our findings, we derive both theoretical and practical implications for the technology and innovation management of firms, and we suggest future research opportunities to further advance this field.
A Tale of Two Educational Revolutions. Human Capital Formation in England in the Long Run

EnglishThis paper charts the growth trajectory of grammar schools in England at the county level between 1270 and 1700 to shed new light on the long-term development of the economy in the centuries before the Industrial Revolution. The evidence on schooling shows that there were two “educational revolutions”. The first occurred in the period between the Black Death and the 1530s, and can probably be attributed to the favourable conditions for schooling created by the European Marriage Pattern (EMP). The second revolution occurred in the second half of the 17th century. Interestingly, this phase of rapid educational expansion was concentrated in the counties in the Northwest of England, which at that time was undergoing rapid urbanisation and commercialisation and which would form the core of the 18th century Industrial Revolution. Moreover, it was the same region that saw a decline of human capital formation during the Industrial Revolution. francaisCet article retrace, au niveau regional, la trajectoire de croissance des Grammar schools en Angleterre entre 1270 et 1700. Il met en evidence l’existence de deux « revolutions educatives ». La premiere eut lieu entre l’episode de la Peste Noire et les annees 1530, et peut etre attribuee aux conditions favorables, en matiere d’education, creees par le modele de mariage europeen (EMP). La seconde revolution remonte a la seconde moitie du dix-septieme siecle. Singulierement, cette phase d’expansion rapide de l’education fut concentree dans les comtes du nord-ouest de l’Angleterre, qui, a cette periode, connurent une phase d’urbanisation et de commercialisation rapide et qui formerent, au dix-huitieme siecle, le cœur de la Revolution Industrielle. De plus, cette meme zone geographique a connu un declin, en matiere de formation de capital humain, pendant la Revolution Industrielle.
Research article GENETIC DIVERGENCE STUDIES IN MUNGBEAN (VIGNA RADIATA L. WILCZEK)

Genetic divergence using D 2 statistic of forty genotypes of various agro-climatic region for ten quantitative characters revealed existence of considerable genetic diversity in the material. The genotypes were grouped into eleven clusters. Cluster VIII contained the highest number of nine genotypes followed by cluster V with seven genotypes. The pattern of distribution of genotypes from different geographical location into eleven clusters were random, demonstrating that geographical isolation may not be the only factor causing genetic diversity. The highest intra-cluster distance was observed for cluster VI (112.02) and the lowest was observed for cluster II (6.24). While the highest inter-cluster distance was observed between cluster III and X (493.41). Harvest index contributed maximum to diversity. Cluster IX with WGG-66 recorded the highest mean for yield contributing characters viz., plant height, branches/plant, pods/plant and clusters/plant. Therefore it was suggested that more emphasis should be given this genotype as parents for crossing with genotypes of other clusters which may produce novel recombinants with desirable traits.
Building Students’ Hard and Soft Skills through Innovative Teaching Approaches to Mathematics

The goals of this case study were to (1) analyze the role of innovative mathematics teaching approaches among middle and high school students regarding their hard and soft mathematical skills; (2) to examine students’ perceptions about the mathematical teaching approaches, used by their teachers during class sessions, (3) to analyze aspects of innovation in them. The descriptive case study approach was used to analyze the role of innovative teaching approaches in helping students to develop various mathematical hard and soft skills. A qualitative meta-analysis methodology was applied to ten student theses about mathematics teaching within the Department of Mathematics in the School of Postgraduate studies of IKIP Siliwangi in Cimahi. This paper presents the results based on ten graduate students’ theses research studies, selected purposively from 68 student theses. The selection of articles aimed to include a variety of theses discussing mathematics skills teaching and learning approaches. The results show that, in general, students who were trained with innovative teaching approaches attained higher grades than students taught by conventional teaching methods. It has been established that students’ grades on mathematical hard skills varied after intervention. On the contrary, regarding students mathematical soft skills, some theses reported no difference between students taught using both approaches, while some reported greater differences. Finally, students had good opinions regarding the innovative teaching-learning approaches, used by their teachers.
Influência da temperatura na germinação de sementes de Annona Montana

Com o objetivo de avaliar a influencia da temperatura sobre a porcentagem de germinacao e o indice de velocidade de germinacao (IVG) de sementes de Annona montana, conhecida como falsa graviola, especie com potencial para porta-enxerto das variedades comerciais, testaram-se quatro temperaturas (20; 25; 30 e 35oC). O trabalho foi desenvolvido em laboratorio em câmaras de germinacao tipo BOD, utilizando-se de sementes de tres plantas provenientes do Banco de Germoplasma do Departamento de Producao Vegetal da Faculdade de Ciencias Agrarias e Veterinarias - UNESP, Câmpus de Jaboticabal-SP. O delineamento experimental foi o inteiramente casualizado, com quatro repeticoes, com dez sementes cada. Pelos resultados obtidos, tem-se que tanto para o parâmetro porcentagem de germinacao como para o IVG, os maiores valores observados foram para as sementes na temperatura de 30oC (55% de germinacao e IVG = 0,153), seguido da temperatura de 25oC (25% de germinacao e IVG = 0,088). Para as temperaturas de 20oC e 35oC, nao foi observada ocorrencia de germinacao. A analise estatistica dos dados de porcentagem de germinacao foi transformada em arc-sen square root (x/100) e as medias foram comparadas pelo teste de Tukey, a 5% de probabilidade.
Nutritional status and clinical evolution of the elderly in home enteral nutritional therapy: a retrospective cohort study*

Objective to evaluate the clinical and nutritional evolution of elderly patients receiving home enteral nutritional therapy. Method retrospective cohort observational study. Data collection was performed through the analysis of clinical and nutritional records. The demographic, nutritional and clinical variables were analyzed. The sample consisted of elderly patients using home enteral nutritional therapy via the probe or the stomach. For the statistical analysis, the Statistical Package for the Social Sciences program was used, adopting the level of significance of 5%. Results the sample was 218 participants, with a mean age of 76 ± 10.12 years, of which 54.1% were female. The main morbidity was the stroke sequelae. Malnutrition was the nutritional diagnosis and the overall subjective assessment, the main instrument of nutritional evaluation. The route of administration of the most prevalent diet was the nasoenteric/nasogastric tube, however, after one year of follow-up, gastrostomy became the main route. It was observed the predominance of general condition maintenance and the most prevalent clinical outcome was death. Conclusion the majority of patients in home enteral nutrition therapy presented maintenance and / or improvement of clinical and nutritional status. Therefore, this therapy may contribute to a better clinical and nutritional evolution.
Design of a Self-Driving Transistor-Based RF-DC Converter Based on Optimized Harmonic-Tuned Rectification Waveforms

In order to apply the traditional power amplifier’s (PA) waveform engineering in an RF-dc rectifier design, a piecewise ON-resistance transistor model is introduced into the derived equations. In this proposed analysis method, the connection between the drain voltage and current is built in order to make the theoretical waveforms easily applied to a practical rectifier design with optimized parameters of the best efficiency. Continuous class-F/inverse class-F and continuous class-B/J waveforms are evaluated with numerical examples in this work. Thus, the rectification performance with different classes and parameters can be compared. This study shows that a continuous class-F and a continuous class-B/J rectifier can barely offer higher than 52% and 70% efficiencies with precise on-duty ratio ( $D$ ) of 0.5, respectively, except by reducing the conduction angle. However, a continuous inverse class-F shows the best rectification efficiency (easily higher than 85%) among all the studied cases for $D=0.5$ . A self-driving inverse class-F design example with optimized parameters is given to verify the theoretical analysis and demonstrate the high-efficiency performance. The rectification efficiencies of 74.9% and 80.7% are measured for 11.2- and 6 W-input powers at 1.9 GHz, respectively.
