How Growth Dynamics Affect Soybean Development across Cultural Practices

The objective of this work was to predict `Packham's Triumph' (Pyrus communis L.) fruit growth as a function of time using an empirical mathematical model. A mature crop was studied at the Experimental Farm of the Comahue National Univ., Rio Negro, Argentina, during the 1992–93, 1993–94, and 1994–95 growing seasons. Trees were selected at random and fruits were collected at weekly intervals. The range of sampling dates was 27 and 178 days after full bloom (DFB). Fresh fruit mass (FM) was measured using an electronic scale (n = 1169). Fruit number/trunk cross-sectional area was also determined; cultural practices were performed according to the local standard program. Equations were developed with SYSTAT procedure. Results showed that the following logistic model provided the most satifactory fit to the pooled data, as compared to the power and linear models: FM (g)= 316.081/(1+ e^5.030–0.039 DFB) R2=0.84 P < 0.001. The accuracy of predictions was tested on an independent crop in the 1995–96 growing season. According to the values of the statistical F test, no significant differences (Pr0.05) were detected between the mean squared deviations of the observed and the estimated values, suggesting that, overall, the model works well. It can provide growers with a means of determining adequate fruit mass at harvest, considering that unless a certain minimum size is obtained, the fruit will be given a lower grade and price.

Harvest Pressure

Asparagus producers have reported a decrease in plant longevity and plant productivity in asparagus fields. Eleven commercial sites (6 in California and 5 in Washington) were monitored starting in Spring 2003. The purpose in monitoring was to evaluate how long-term growth dynamics are affected by harvest pressure. Sites were planted as crowns in Spring 2002 and farm irrigation methods included furrow, sprinkler, and drip. Most sites were harvested starting in Spring 2003 at varying pressures. Harvest yields ranged from 0 to 1300 kg·ha-1. Carbohydrate (CHO) levels in the roots were sampled over the entire growing season and assessed with AspireUS (www.aspireus.com). At the last sampling in Oct. and Nov. 2003, CHO levels ranged from 438 mg·g-1 to 712 mg·g-1 (97% to 158% of the ideal). This resulted in a root CHO load of 2.6 to 6.3 megagrams/hectare. Root mass and distribution was sampled in Spring 2003 and again at the end of the growing season. Root biomass increased by 18% to 487% of the previous year's growth. Fern number, fern mass and plant population were also sampled. Fern number ranged from 3.2 to 6.4 stems per plant and total fern weight ranged from 8.9 to 36.2 megagrams/hectare. Plant populations were reduced by 3% to 19% when compared to the initial planted population. Findings suggest that excessive harvest pressure in the year after planting adversely affects storage CHO accumulation and root growth. Additional site monitoring will occur through 2005.

Abstract We consider the ways humans engage in social epistemic actions, to guide each other's attention, prediction, and learning processes towards salient information, at the timescale of online social interaction and joint action. This parallels the active guidance of other's attention, prediction, and learning processes at the longer timescale of niche construction and cultural practices, as discussed in the target article.

Microstructure of epitaxial layers of doped GaAs and its crystal growth dynamics on single crystal GaAs substrate were studied by Raman microspectroscopy with a Dilor OMARS instrument equipped with a 1024 photodiode multichannel detector and a ion-argon laser Spectra-Physics emitting at 514.5 nm.The spatial resolution of this technique, less than 1 μm2, allows the recording of Raman spectra at several spots in function of thickness, from the substrate to the outer deposit, including areas around the interface (Fig.l).The high anisotropy of the LO and TO Raman bands is indicative of the orientation of the epitaxial layer as well as of the structural modification in the deposit and in the substrate at the interface.With Sn doped, the epitaxial layer also presents plasmon in Raman scattering. This fact is already very well known, but we additionally observed that its frequency increases with the thickness of the deposit. For a sample with electron density 1020 cm-3, the plasmon L+ appears at 930 and 790 cm-1 near the outer surface.

Bagi sesebuah negara yang mempunyai etnik pelbagai anutan kepercayaan dan perbezaan amalan budaya, dialog antara agama berperanan membetulkan semula kekaburan dalam kehidupan beragama dan berbudaya. Melalui peranan Saudara Baru, dialog antara agama mampu menjadi medan bagi menjelaskan kebenaran tentang agama Islam kepada masyarakat bukan Muslim dan pelaksanaan amalan budaya asal kepada Muslim asal. Objektif kajian ini ialah melihat pengalaman pelaksanaan dialog antara agama di Terengganu dan relevansi dalam kehidupan beragama di negara Brunei. Metode kajian ini menggunakan kajian dokumen yang menyentuh komuniti Cina Muslim di Terengganu dan Brunei. Pengalaman pelaksanaan dialog antara agama di Terengganu dan negara Brunei memperlihatkan dialog antara agama mampu membetulkan salah faham dan selanjutnya mengendurkan ketegangan hubungan antara agama dan budaya antara komuniti Saudara Baru, ahli keluarga bukan Muslim dan masyarakat Muslim asal. Biarpun begitu, adalah dicadangkan agar kajian yang menyentuh dialog antara agama perlu diperkukuhkan sebagai medium membina semula peradaban memandangkan penduduk di kedua-dua lokasi ini terdiri daripada berbilang etnik dan agama sedangkan pada masa yang sama masalah yang menyentuh hubungan antara agama sentiasa timbul. Abstract: For a country with diverse ethics of beliefs and cultural practices, interfaith dialogue plays a role to redefine ambiguity in religious and cultural life. Through the role of the New Muslim (Muslim Convert), interfaith dialogue can become a medium to explain the truth about Islam to the non-Muslims and the implementation of real cultural practices to the others Muslim. The objective of this study is to examine the experience of interfaith dialogue in Terengganu and in Brunei. The method of this study is being conducted in document research that related with the Muslim Chinese community in Terengganu and Brunei. In addition, interviews with people involved in the management of New Muslims also carried out. The experience of interfaith dialogue in Terengganu and Brunei shows that dialogue capable explains misunderstandings and further loosening the tension between religion and culture among New Muslims, non-Muslim family members and Muslim communities. However, it is recommended that studies on interfaith dialogue should be strengthened as a medium for rebuilding civilization as the residents of both locations are multi-ethnic and religious while at the same time the problem of interreligious persists.

Point Of Departure

From a remarkably innovative point of departure, Ben Highmore (University of Sussex) suggests that modernist literature and art were not the only cultural practices concerned with reclaiming the everyday and imbuing it with significance. At the same time, Roger Caillois was studying the spontaneous interactions involved in games such as hopscotch, while other small scale institutions such as the Pioneer Health Centre in Peckham, London attempted to reconcile systematic study and knowledge with the non-systematic exchanges in games and play. Highmore suggests that such experiments comprise a less-often recognised ‘modernist heritage’, and argues powerfully for their importance within early-twentieth century anthropology and the newly-emerged field of cultural studies.

The Way

Covering the period from 709 to 871, this chapter traces the initial conversion of Afghanistan from Zoroastrianism and Buddhism to Islam. Highlighting the differential developments in four regions of Afghanistan, it discusses the very earliest history of Afghan Islam both as a religion and as a political system in the form of a caliphate. The chapter draws on under-utilized sources, such as fourth to eighth century Bactrian documents from Tukharistan and medieval Arabic and Persian histories of Balkh, Herat and Sistan. In so doing, it offers a paradigm shift in the way early Islam is understood by arguing that it did not arrive in Afghanistan as a finished product, but instead grew out of Afghanistan’s multi-religious context. Through fusions with Buddhism, Zoroastrianism, early Abrahamic traditions, and local cult practices, the Islam that resulted was less an Arab Islam that was imported wholesale than a patchwork of various cultural practices.
