Humoral Immune Response of Immunized Sows with Recombinant Proteins of Enterotoxigenic Escherichia coli  [PDF]
Daniele Araujo Pereira, Caio Abércioda Silva, Mario Augusto Ono, Odilon Vidotto, Marilda Carlos Vidotto
World Journal of Vaccines (WJV) , 2015, DOI: 10.4236/wjv.2015.51008
Abstract: Enteric disorders in pigs are related to the fimbriae F4 (K88), F5 (K99), F6 (987P), F41 and F18 of enterotoxigenic Escherichia coli (ETEC). Immunization of sows with adhesins is important to stimulate the production of antibodies and the consequent transfer of these to the piglets via colostrum to prevent diarrhea during the neonate period and after weaning. The objective of this study was to evaluate the immune response of the sows immunized with recombinant ETEC proteins (F4, F5, F6, F18 and F41). The immune response of the sows immunized with the recombinant proteins was compared with a commercial vaccine containing ETEC bacterins. The study was performed on a commercial farm and included nine pregnant sows divided into three groups: G1 was vaccinated with recombinant proteins (n = 3); G2 was vaccinated with the commercial vaccine (n = 3); and G3 was vaccinated with sterile buffered saline (PBS) (n = 3). All the sows were fed a balanced diet without antibiotics and water ad libitum. The recombinant fimbriae stimulated the specific humoral immune response of the immunized sows. There was a statistically significant increase in the levels of antibodies to the fimbriae F4 (K88), F5 (K99), F6 (987P) and F18 in the sows vaccinated with the recombinant proteins compared with the control group. The colostrum IgG titers for all fimbriae in all the immunized sows were significantly increased compared to the control group. Additionally, all the piglets exhibited significantly increased antibody levels relative to all fimbriae when compared with those in the unimmunized control group, demonstrating successful antibody transfer via colostrum of the sows to the piglets.

A Simple Trade Model with an Optimal Exchange Rate Motivated by Discussion of a Renminbi Float  [PDF]
Hui Huang, Yiming Wang, John Whalley, Shunming Zhang
Modern Economy (ME) , 2012, DOI: 10.4236/me.2012.35069
Abstract: We present a model of combined inter-spatial and inter-temporal trade between countries in which there is a fixed ex-change rate with a surrender requirement for foreign exchange generated by exports. The model incorporates inter- temporal intermediation services, which may or may not be liberlized across countries. We use numerical simulation methods to explore the properties of the model, since it has no closed form solution. In this model, when services re-main unliberalized there is an optimal trade intervention, even in the small open price taking economy case. Given monetary policy and an endogenously determined premium value on foreign exchange, an optimal setting of the ex-change rate can provide the optimal trade intervention. We suggest this model may have loose relevance for the current situation in China where services remain unliberalized and tariff rates are bound in the WTO and a free Renminbi float is under discussion.
Observation of Vortex Lattice Related Anomalies in Polycrystalline YBa2Cu3O7-x Near the Superconducting Transition  [PDF]
S. B. Ota
Journal of Modern Physics (JMP) , 2012, DOI: 10.4236/jmp.2012.310183
Abstract: The d.c. I-V characteristic of polycrystalline YBa2Cu3O7-x high temperature superconductors (HTSC) is measured near the transition temperature (Tc). The Tc was found to be 90 K with a width of 2 K. The voltage was measured at various current values and with reversing the current. A difference in voltage was found for forward and reverse current directions near Tc. The observed directionality of the I-V characteristic can be understood in terms of quantized magnetic flux by the self-field of the current and the proximity junctions in these materials. This can also be understood qualitatively as due to the d-wave superconductivity. The measured dc voltage showed increased noise near Tc which is possibly related to 1/f noise due to the motion of Abrikosov flux lines.
A High Power-Added-Efficiency 2.5-GHz Class-F Power Amplifier Using 0.5 μm GaN on SiC HEMT Technology  [PDF]
Chia-Han Lin, Hsien-Chin Chiu, Min-Li Chou, Hsiang-Chun Wang, Ming-Feng Huang
Journal of Computer and Communications (JCC) , 2016, DOI: 10.4236/jcc.2016.43011
Abstract:

This paper proposed the high-frequency, multi-harmonic-controlled, Class-F power amplifier (PA) implemented with 0.5 μm GaN Hetrojunction Electron Mobility Transistor (HEMT). For PA design at high frequencies, parasitics of a transistor significantly increase the difficulty of harmonic manipulation, compared to low-frequency cases. To overcome this issue, we propose a novel design methodology based on a band-reject, low-pass, output matching network, which is realized with passive components. This network provides optimal fundamental impedance and allows harmonic control up to the third order to enable an efficient Class-F behavior. The implemented PA exhibits performance at 2.5 GHz with a 50% PAE, 14 dB gain, and 10 W output power.

Abstract: Fritillary is a precious Chinese medicinal herb. Those native to Xinjiang Northwest China, are even more distinguished from other sources for their purity and effectiveness. Fritillaria in Xinjiang comprises 8 native species and one (F. thunbergii Miq.) introduced from Zhejiang, East China. In this paper the authors describe the karyotypes of 6 species native to Xinjiang and F. thunbergii Miq., of which five, i.e.F. olgae Vved., F. walujewii Regel, F. yuminensis X. Z. Duan, F. karelinii (Fisch.) Baker and F. thunbergii Miq. were studied for the first time. Detail observation and measur- ment of chromosomes in each of them were made. The data obtained may be summa- rized as follows: scietific name karyotype formula (2n=) F. pallidiflora Schrenk 2m + 2sm + 6st + 14t F. olgae Vved. 4m + 6st + 14t F. walujewii Regel 2m + 2sm + 8st+ 12t F. yuminensis X. Z. Duan 4m + 8st + 12t F. verticillata Willd 4m + 8st + 12t F. karelinii (Fisch.) Baker 4m + 4sm + 4st + 12t F. thunbergii Miq. 2m + 2sm + 4st + 16t The karyotype of the native species are, on the whole, similar to each other except that of F. karelinii (Fisch.) Baker, a species inhabiting desert areas. The number of m-sm chromosomes has increased from 2 to 4 and the number of st-t chromosomes decreased correspondently. So is the karyotype of F. thunbergii Miq. which is noted for its high ratio of long chromosome/short chromosome and the more t-chromosomes. These two peculiar karyotypes coincide amazingly with their specific natural habitats.

Abstract: The paper describes the symptoms of the Fusarium wilt and necrosis of root and lower stem of soybean, which include leaf chlorosis, wilt of the apical portion of the plant, necrosis of the root and lower stem, and wilting of the whole plant. The pods are often poorly developed. The seeds may be smaller and lighter in the weight and infected, as well. Isolated from diseased soybean plants were the species Fusarium avenaceum, F. equiseti, F. oxysporum and F. poae. Pathogenicity tests under artificial infection conditions showed F. oxysporum (isolate S/1) to be the most pathogenic among of the four investigated species. The other species proved much less pathogenic.

Abstract: This paper examines fiscal policy, monetary policy and real exchange rate in Turkish foreign trade from global point of view. While importance of foreign trade is rapidly increasing in the globalization age at the world, active policy applications have undergone extremely significant implications. In this paper relation between foreign trade and real exchange rate, budget deficit and M1 money supply is thoroughly examined with causality tests. For these variables first of all ADF unit root tests are carried out. All of them are found to be same degree integrated. Than, long run relations among the variables are examined with VAR analysis. Provided with the long run relation, VAR is estimated. Finally Granger causality tests based on VAR. Keywords: Foreign trade, real exchange rate, monetary policy, fiscal policy, impossible trinity
