ABSTRACT<br />The limited fertile land and increasing flood intensity as a result of global climate changes become serious constraints in the sustainability of national rice production. Improvement of rice varieties, especially for rice cultivation in swampy area is necessary. The objective of this research were to evaluate responses and productivity of rice genotypes to stagnant flooding stress which occurs on swampy area. A total of 22 genotypes had been tested, included Tapus, IR42, and IR64 as check varieties. Water level at stagnant flooding environment was 50-60 cm and started from 35 days after planting until harvest. Research was conducted in wet season of 2011/2012 at Babakan Experimental Farm, Bogor Agricultural University. The experiment used randomized block design with three replicates. The results showed that stagnant flooding stress caused an increase in plant height, flowering and maturity date, number of unfilled grain, and stem elongation ability. On the other hand, the number of productive tiller and the number of filled grain decreased. The number of filled grain positively correlated with grain yield (r = 0.74**), but stem elongation ability didn’t have strong correlation with grain yield (r = -0.29). Genotypes IPB107-F-5-1-1 and IPB107-F-82-2-1 showed the highest productivity, 5.47 ton ha-1 and 5.80 ton ha-1,, respectively, at which productivity decreased up to 20% compared to optimum condition. <br />Keywords: basin swampy rice, stagnant flooding

Oil palm is one of the important plantation crops in the plantation sector. Increased oil palm plantation area causes the need for the availability of oil palm seedlings in large quantities. Good quality oil palm seedlings were obtained through intensive maintenance especially fertilization. Fertilizers needed for the growth of oil palm seedlings include calcium and magnesium fertilizers. The objective of this experiment was to determine the optimum rates of calcium and magnesium fertilizer for oil palm seedling (Elaeis guineensis Jacq.). This experiment was conducted at Cikabayan Experimental Station, IPB Darmaga, Bogor, from December 2011 to November 2012. The experimental design used was factorial randomized block design with three replications. The first factor was Ca fertilizer rates i.e., 0, 5, 10, and 20 g CaCO3 plant-1. The second factor was Mg fertilizer rates, i.e., 0, 24, 48, and 96 g MgSO4 plant-1. The results showed that calcium affected stomatal density, whereas magnesium fertilizer affected morphological and physiological variables (stomatal density and chlorophyll content) of oil palm seedling. Based on the plant height and stem diameter, the recommended rate of magnesium fertilizer for 8 months oil palm seedlings in the main nursery was 58 g plant-1. This total rate should be applied at different amount every month from 1-8 month, at 2.0, 2.0, 8.0, 9.3, 8.8, 9.3, 9.4 and 9.3 g MgSO4 plants-1, respectively. The optimum rate of calcium fertilizer was not able to be determined in this research. <br />Keywords: chlorophyll, leaf, morphology, physiology

ABSTRACT<br /><br />Somatic embryo induction medium was reported to be genotype dependent for soybean. This study was aimed to obtain the optimum medium for embryo somatic induction and proliferation, and to regenerate somatic embryo of five soybean genotypes. Five soybean genotypes (Tanggamus, Anjasmoro, Yellow Biloxi, CG-22-10, and SP-10-4) were used in this study. The research was divided into four steps: (1) embryogenic callus induction of five soybean genotypes, (2) embryogenic callus proliferation of five soybean genotypes, (3) optimation of embryo somatic induction on five soybean genotypes and (4) embryo somatic regeneration of five soybean genotypes. The induction experiment showed that based on number of embryogenic callus, the best somatic embryo-induction medium was 3% sucrose+ NAA 5 mg L-1+2,4-D 5 mg L-1+ Vitamin B5. Embryogenic callus number for each genotype tested was increased on proliferation media of 3% sukrosa + 2,4-D 5 mg L-1 + NAA 5 mg L-1+ Vit B5, and Yellow Biloxi gave the highest number of proliferated somatic embryos compared to other genotypes. Increasing number of globular somatic embryo of all genotypes was obtained from the optimation of somatic embryo induction media being used, and Tanggamus genotype gave the highest number of globular somatic embryo which followed by Yellow Biloxi genotype. Tanggamus and Yellow Biloxi genotypes were also successfully formed the four steps of somatic embryos (globular, heart, torpedo, and cotyledonary stages), but in regeneration medium of MS0 and media MS + sukrosa 10 g L-1 + GA3 2 mg L-1 + BAP 4 mg L-1 + Vit B5 only Tanggamus genotype was regenerated into plantlet. <br /><br />Keywords: 2,4-D, NAA, somatic embryos, induction, proliferation<br /><br />

Ginger, the rhizome of the Zingiber officinale, a herbaceous tropical perennial plant which belong to the family Zingiberaceae. Ginger is a non-toxic highly promising natural compound having a wide spectrum of biological functions. In this study, selected bioactive components of ginger were computationally evaluated for therapeutic potential in relevance to human diseases using standard bioinformatics tools such as Pubchem, Swisstargetprediction and Swissadme. The result of this study showed that most of the targets obtained such as 5- hydroxytryptamine receptors, carbonic anhydrases and zinc finger proteins, have not been adequately researched in relation to the therapeutic potential of ginger. Ginger showed high potential in the prevention and management of cancer, neurodegenerative dementia and cardiovascular diseases in human, which could be administered alone or in combination with other drugs.

„Involvierte“ Väter zwischen Beruf und Familie. Zur Re/Produktion von Männlichkeiten in paarinternen Aushandlungen
Authors: Peukert Almut 
Published: April 2017

Starting from the hypothesis discussed in research on masculinities and fathering that ‘involved’ fathering is incompatible with hegemonic masculinity, this paper examines continuity and change in interrelating work and family life by German fathers. Within the sociological frame of interaction theory on un/doing masculinity I focused on the production and presentation of gender differences and the hierarchizing demarcation against femininity and non-hegemonic masculinities within the couple. Based on 27 qualitative couples’ and individual interviews, three forms of re/production of masculinity were constructed and discussed along the dimensions of vocational/career concepts, financial care of the family, and parental leave arrangements within the couple. The results show that the re/production of masculinities within negotiations of the couples regarding paid and family work are fragile, challenged, or episodically undone. This implies that in addition to welfare state policies and work organizations, the negotiations within the couple about their division of paid and unpaid work have significant consequences for the un/equality between the parents.
Zusammenfassung
Ausgehend von der in der Männlichkeitsforschung diskutierten These, ‚involvierte‘ Väterlichkeit stehe im Widerspruch zum Leitbild erwerbszentrierter hegemonialer Männlichkeit, werden im vorliegenden Beitrag Kontinuitäten und Wandel in der Relationierung von Erwerbs- und Familienarbeit bei Vätern untersucht. Mit dem interaktionstheoretischen Ansatz zu ‚un/doing masculinity‘ liegt der Fokus auf der Her- und Darstellung von Geschlechterdifferenzen sowie der hierarchisierenden Abgrenzung zu Weiblichkeiten und nicht-hegemonialer Männlichkeiten im Paarkontext. Anhand von 27 qualitativen Paar- und Einzelinterviews werden – entlang der Dimensionen Berufs-/Karrierekonzept, finanzielle Versorgung der Familie und Elternzeitarrangement – drei Re/Produktionsformen erwerbszentrierter hegemonialer Männlichkeit rekonstruiert und diskutiert. Im Ergebnis zeigt sich, dass die Re/Produktion von Männlichkeiten in paarinternen Aushandlungen zu Erwerbs- und Familienarbeit fragil, herausgefordert oder episodisch ausgesetzt wird. Dies impliziert, dass auch die Aushandlungen auf der Paarebene zur Relationierung von Erwerbs- und Familienarbeit, neben wohlfahrtsstaatlichen Rahmungen und Arbeitsorganisationen, signifikante un/gleichheitsrelevante Folgen haben.

Abstract
Natural pathogens, such as viruses, often induce T-dependent and T-independent Ab responses. However, the activation and differentiation of Ag-specific B cells under these conditions had not been examined in detail. In this study, we used bacterial phage Qβ-derived virus-like particles (Qβ-VLPs) as an immunogen to examine the T-independent and T-dependent phases of the response in mice. Using Qβ-specific cell labeling and enrichment methods developed in this study, we were able to characterize the rare Ag-specific B cells in detail. Surprisingly, we found that Qβ-VLPs could induce Bcl-6 expression in pregerminal center B cells independently of T cell help. In addition, Qβ-VLP–induced T-independent responses could lead to isotype-switched and somatically mutated memory B cells. Finally, in contrast to what has been reported with several other Ags, long-lived IgG+ memory cells were induced by Qβ-VLPs, with IgM+ memory B cells being produced but only evident for a limited time, suggesting that different types of immunogens may preferentially generate or maintain IgM+ versus IgG+ memory B cells.

Abstract
RNA-based vaccines have recently emerged as a promising alternative to the use of DNA-based and viral vector vaccines, in part because of the potential to simplify how vaccines are made and facilitate a rapid response to newly emerging infections. SAM vaccines are based on engineered self-amplifying mRNA (SAM) replicons encoding an Ag, and formulated with a synthetic delivery system, and they induce broad-based immune responses in preclinical animal models. In our study, in vivo imaging shows that after the immunization, SAM Ag expression has an initial gradual increase. Gene expression profiling in injection-site tissues from mice immunized with SAM-based vaccine revealed an early and robust induction of type I IFN and IFN-stimulated responses at the site of injection, concurrent with the preliminary reduced SAM Ag expression. This SAM vaccine-induced type I IFN response has the potential to provide an adjuvant effect on vaccine potency, or, conversely, it might establish a temporary state that limits the initial SAM-encoded Ag expression. To determine the role of the early type I IFN response, SAM vaccines were evaluated in IFN receptor knockout mice. Our data indicate that minimizing the early type I IFN responses may be a useful strategy to increase primary SAM expression and the resulting vaccine potency. RNA sequence modification, delivery optimization, or concurrent use of appropriate compounds might be some of the strategies to finalize this aim.
δ13C decreases in the upper western South Atlantic during Heinrich Stadials 3 and 2

Abstract. Abrupt millennial-scale climate change events of the last deglaciation (i.e. Heinrich Stadial 1 and the Younger Dryas) were accompanied by marked increases in atmospheric CO2 (CO2atm) and decreases in its stable carbon isotopic ratios (δ13C), i.e. δ13CO2atm, presumably due to outgassing from the ocean. However, information on the preceding Heinrich Stadials during the last glacial period is scarce. Here we present δ13C records from two species of planktonic foraminifera from the western South Atlantic that reveal major decreases (up to 1 ‰) during Heinrich Stadials 3 and 2. These δ13C decreases are most likely related to millennial-scale periods of weakening of the Atlantic meridional overturning circulation and the consequent increase (decrease) in CO2atm (δ13CO2atm). We hypothesise two mechanisms that could account for the decreases observed in our records, namely strengthening of Southern Ocean deep-water ventilation and weakening of the biological pump. Additionally, we suggest that air–sea gas exchange could have contributed to the observed δ13C decreases. Together with other lines of evidence, our data are consistent with the hypothesis that the CO2 added to the atmosphere during abrupt millennial-scale climate change events of the last glacial period also originated in the ocean and reached the atmosphere by outgassing. The temporal evolution of δ13C during Heinrich Stadials 3 and 2 in our records is characterized by two relative minima separated by a relative maximum. This w structure is also found in North Atlantic and South American records, further suggesting that such a structure is a pervasive feature of Heinrich Stadial 2 and, possibly, also Heinrich Stadial 3.

Abstract. An accurate estimation of water resources dynamics is crucial for proper management of both agriculture and the local ecology, particularly in semi-arid regions. Imperfections in model physics, uncertainties in model land parameters and meteorological data, as well as the human impact on land changes often limit the accuracy of hydrological models in estimating water storages. To mitigate this problem, this study investigated the assimilation of terrestrial water storage variation (TWSV) estimates derived from the Gravity Recovery And Climate Experiment (GRACE) data using an ensemble Kalman filter (EnKF) approach. The region considered was the Hexi Corridor in northern China. The hydrological model used for the analysis was PCR-GLOBWB, driven by satellite-based forcing data from April 2002 to December 2010. The impact of the GRACE data assimilation (DA) scheme was evaluated in terms of the TWSV, as well as the variation of individual hydrological storage estimates. The capability of GRACE DA to adjust the storage level was apparent not only for the entire TWSV but also for the groundwater component. In this study, spatially correlated errors in GRACE data were taken into account, utilizing the full error variance–covariance matrices provided as a part of the GRACE data product. The benefits of this approach were demonstrated by comparing the EnKF results obtained with and without taking into account error correlations. The results were validated against in situ groundwater data from five well sites. On average, the experiments showed that GRACE DA improved the accuracy of groundwater storage estimates by as much as 25 %. The inclusion of error correlations provided an equal or greater improvement in the estimates. In contrast, a validation against in situ streamflow data from two river gauges showed no significant benefits of GRACE DA. This is likely due to the limited spatial and temporal resolution of GRACE observations. Finally, results of the GRACE DA study were used to assess the status of water resources over the Hexi Corridor over the considered 9-year time interval. Areally averaged values revealed that TWS, soil moisture, and groundwater storages over the region decreased with an average rate of approximately 0.2, 0.1, and 0.1 cm yr−1 in terms of equivalent water heights, respectively. A particularly rapid decline in TWS (approximately −0.4 cm yr−1) was seen over the Shiyang River basin located in the southeastern part of Hexi Corridor. The reduction mostly occurred in the groundwater layer. An investigation of the relationship between water resources and agricultural activities suggested that groundwater consumption required to maintain crop yield in the growing season for this specific basin was likely the cause of the groundwater depletion.
