Feasibility of Low-Cost Seed Potato Storage in Kenya: The Case of Diffused Light Storage in Nyandarua County

An on-farm storage trial was conducted at six sites in Nyandarua County using seed tubers of eight officially recognized Kenyan potato varieties and one commonly grown farmers' variety called Cangi.The seeds were stored under diffuse light store (DLS) conditions in low-cost structures owned by the growers to test the feasibility of prolonged seed storage under on-farm conditions.Three farmers' groups and three individual farmers were used in this study.In general, DLS wooden structures with iron sheet roof or mud-walled with iron sheet roofs were used for storage.Most of the varieties stored satisfactorily for up to 8 months.Kenya Mpya and Kenya Mavuno had higher overall acceptability than Sherekea, Asante, Desiree, Kenya Karibu, Tigoni and Dutch Robjin.Kenya Mpya, Sherekea and Kenya Mavuno had the least shrinkage following 8 months of storage.The unofficial cultivar Cangi which is the most popular in Nyandarua had poor storability but could be planted 2 to 3 months following harvest.Results indicated that DLS could be used by ware potato growers for prolonged seed storage the following season.This way the growers could be assured of good potato harvests due to the use of well sprouted tubers.This is critical in case of seasons with low or less than average rainfall as experienced in recent years.

No galaxy left behind: accurate measurements with the faintest objects in the Dark Energy Survey

Accurate statistical measurement with large imaging surveys has traditionally required throwing away a sizable fraction of the data. This is because most measurements have relied on selecting nearly complete samples, where variations in the composition of the galaxy population with seeing, depth, or other survey characteristics are small. We introduce a new measurement method that aims to minimize this wastage, allowing precision measurement for any class of detectable stars or galaxies. We have implemented our proposal in &lt;scp&gt;balrog&lt;/scp&gt;, software which embeds fake objects in real imaging to accurately characterize measurement biases. We demonstrate this technique with an angular clustering measurement using Dark Energy Survey (DES) data. We first show that recovery of our injected galaxies depends on a variety of survey characteristics in the same way as the real data. We then construct a flux-limited sample of the faintest galaxies in DES, chosen specifically for their sensitivity to depth and seeing variations. Using the synthetic galaxies as randoms in the Landy–Szalay estimator suppresses the effects of variable survey selection by at least two orders of magnitude. With this correction, our measured angular clustering is found to be in excellent agreement with that of a matched sample from much deeper, higher resolution space-based Cosmological Evolution Survey (COSMOS) imaging; over angular scales of 0&lt;f&gt;$_{.}^{\\circ}$&lt;/f&gt;004 &lt; θ &lt; 0&lt;f&gt;$_{.}^{\\circ}$&lt;/f&gt;2, we find a best-fitting scaling amplitude between the DES and COSMOS measurements of 1.00 ± 0.09. We expect this methodology to be broadly useful for extending measurements’ statistical reach in a variety of upcoming imaging surveys.

Multiple Time-Frequency Curve Classification for Tacho-Less and Resampling-Less Compound Bearing Fault Detection Under Time-Varying Speed Conditions

Rotating machinery usually runs at time-varying speeds, which often brings failures, especially compound faults. However, currently, there is still a lack of satisfactory coupled fault diagnosis methods at variable speeds. Several methods have been developed, which try to eliminate rotational speed influences by converting nonstationary fault characteristic frequencies into stationary ones. But it brings new problems of computational efficiency and accuracy, and requires an auxiliary tachometer to measure the rotational speed. Time-frequency analysis can solve the problems, and extract time-frequency curves for fault diagnosis through time-frequency representation (TFR). However, for signals containing multiple faults at variable speeds, uninterested components will be generated when extracting multiple time-frequency curve (MTFC), which makes it difficult for compound fault diagnosis. To solve these problems, a novel MTFC classification method for tacho-less and resampling-less compound bearing fault detection under time-varying speed conditions is proposed in this paper. Here the TFR characteristics of a multi-fault vibration signal is analyzed, and a compound fault diagnosis strategy based on MTFC classification is developed. Firstly, MTFC is extracted by a local peak search method. Then, according to the relationship between instantaneous shaft rotational frequency, instantaneous fault characteristics frequency and their respective harmonics, two classification criteria for curves are proposed and MTFC is classified into interested curves and uninterested curves. Finally, the average ratios between interested curves are matched to theoretical fault characteristic coefficients to determine the fault type. Case studies on rolling bearing experiments verified the effectiveness and superiority of the proposed method.

Argentina's Turmoil: The Politics of Informality and the Roots of Economic Meltdown

This article argues that Argentina's current economic crisis cannot be fully understood without an analysis of recent political processes. It defines the politics of informality that have characterised Argentina's democracy-building processes. This de-institutionalisation of politics was perceived as the facilitator of democratic consolidation, state reform and economic restructuring. In practice, the politics of informality contributed to the crisis of 2001. The article begins by analysing the scale of the political and economic crisis from 1999. It is followed by an analysis of the politics of informality implemented by the Raúl Alfonsín and Carlos Menem's governments and then goes on to explain the consequences of informal politics. Finally, it concludes by outlining the main factors that conspire against democracy and economic stability in Argentina.

Building plug and play power applications using abstract object modeling

This paper addresses the computer industry's general inability to develop complex software applications in a manner that promotes easy integration, reusability and low maintenance. Most complex applications are built for a very specific environment and include far too many dependencies, making them difficult to maintain and expensive to integrate. A development methodology known as Abstract Object Modeling is discussed that overcomes this limitation and a simple power application known as a linear powerflow is used as an example. The powerflow is first discussed in terms of a traditional approach, then in terms of the abstract object modeling.

The embedded machine

The Embedded Machine is a virtual machine that mediates in real time the interaction between software processes and physical processes. It separates the compilation of embedded programs into two phases. The first phase, the platform-independent compiler phase, generates E code (code executed by the Embedded Machine), which supervises the timing, not the scheduling of, application tasks relative to external events such as clock ticks and sensor interrupts. E code is portable and, given an input behavior, exhibits predictable (i.e., deterministic) timing and output behavior. The second phase, the platform-dependent compiler phase, checks the time safety of the E code, that is, whether platform performance (determined by the hardware) and platform utilization (determined by the scheduler of the operating system) enable its timely execution. We have used the Embedded Machine to compile and execute high-performance control applications written in Giotto, such as the flight control system of an autonomous model helicopter.

An Alternative Role for Acetylenes: Activation of Fluorobenzenes toward Nucleophilic Aromatic Substitution

Acetylenes are increasingly versatile functional groups for a range of complexity-building organic transformations and for the construction of desirable molecular architectures. Herein we disclose a previously underappreciated aspect of arylacetylene reactivity by utilizing alkynes as electron-withdrawing groups (EWG) for promoting nucleophilic aromatic substitution (S(N)Ar) reactions. Reaction rates for the substitution of 4-(fluoroethynyl)benzenes by p-cresol were determined by (1)H NMR spectroscopy, and these rate data were used to determine substituent (Hammett) constants for terminal and substituted ethynyl groups. The synthetic scope of acetylene-activated S(N)Ar reactions is broad; fluoroarenes bearing one or two ethynyl groups undergo high-yielding substitution with a variety of oxygen and arylamine nucleophiles.

Antibody Immobilization on Waveguides Using aFlow–Through System Shows Improved Listeria monocytogenesDetection in an Automated Fiber Optic Biosensor: RAPTORTM

Recent outbreaks of food borne illnesses continue to support the need for rapidand sensitive methods for detection of foodborne pathogens. A method for detecting Listeriamonocytogenes in food samples was developed using an automated fiber-optic-basedimmunosensor, RAPTORTM. Detection of L. monocytogenes in phosphate buffered saline(PBS) was performed to evaluate both static and flow through antibody immobilizationmethods for capture antibodies in a sandwich assay. Subsequent detection in frankfurtersamples was conducted using a flow through immobilization system. A two stage blockingusing biotinylated bovine serum albumin (b-BSA) and BSA was effectively employed toreduce the non-specific binding. The sandwich assay using static or flow through mode ofantibody immobilization could detect 1

Peptidoglycan of Free-Living Anaerobic Spirochetes

Electron microscope examination of negatively stained or thin-sectioned cells of Spirochaeta stenostrepta treated with penicillin or lysozyme showed that the peptidoglycan was present as a thin, electron-dense layer adjacent and external to the cytoplasmic membrane. The peptidoglycan was isolated from cells of S. stenostrepta and Spirochaeta litoralis by a procedure including treatments with sodium lauryl sulfate and Pronase. Hydrolysates of the isolated S. stenostrepta and S. litoralis peptidoglycans contained glucosamine, muramic acid, glutamic acid, l -ornithine, and alanine in molar ratios of 0.90:0.85:1.00:1.00:1.40 and of 0.63:0.63:0.99:1.00:1.41, respectively. Determination of N-terminal residues suggested that nearly 50% of the ornithine in S. stenostrepta and S. litoralis peptidoglycans was involved in peptide cross-linkage. The peptidoglycan layer of S. stenostrepta was sensitive to lysozyme and myxobacter AL-1 protease.

Assessing the willingness to change: optimising behaviour change in the management of chronic eye conditions

Background: Globally, low vision self-management programmes remain relatively novel, with limited discussion on how acceptance, motivation and readiness to change affect successful and sustainable behaviour change. Aim: To explore the relationship between acceptance, motivation and readiness to change in a group of people participating in low vision self-management programmes. Methods: A participatory action research framework was used with a steering group comprising clinicians and researchers to identify barriers to participation and challenges in the implementation of a self-management low vision programme in Singapore. Results: Many participants were not ready to make changes as they not only did not accept their condition, but were also unmotivated to make changes. We also found that the programme did not meet the psychosocial needs of the participants. Conclusions: Prior to inclusion in self-management programmes, it is recommended that motivational interviewing strategies are used to assess whether individuals have accepted their condition and are ready and motivated to make changes. It is essential that programmes address issues, such as: the emotional consequences of low vision; grief; communicating feelings; and coping strategies.

Near Term Suicide Risk Assessment: A Commentary on the Clinical Relevance of Protective Factors

In this article we examine the clinical relevance of protective factors to the assessment and formulation of near-term risk of death by suicide. Contrary to current clinical belief and practice, we posit that there is no evidence base to support these factors as mitigating or buffering risk for suicide for the individual patient, especially in the near-term assessment of that suicide risk. We show that evidence-based protective factors derive from population-based studies and, applicably, have relevance to public health promotion/primary prevention and are significant in informing treatment/secondary prevention, but they lack evidence to support their often-proposed role in mitigating or buffering risk for suicide on an individual basis, especially when applied to the assessment of near-term risk of suicide. Accordingly, we argue for the need for empirical study of the role protective factors may or may not play in the formulation of a patient's risk for suicide and, in the interim, for clinical caution in assuming that protective factors have any significant buffering effect on a patient's level of near-term risk.

10 YEAR FOLLOW UP OF ANTERIOR CRUCIATE LIGAMENT RECONSTRUCTION IN 30 PATIENTS USING SPECT BONE SCANNING

The incidence of osteoarthritis (OA) after an ACL reconstruction is not clear. Reports estimate between 12% and 61% at 8 years post ACL reconstruction. Single Photon emission Computed Tomography (SPECT) scanning (a 3 dimensional radionuclide bone scan) is a sensitive and quantitative method of assessing knee OA, with abnormalities appearing before plain xray and arthroscopic changes.Aim: to objectively assess the long term result of ACL reconstruction using SPECT.Method: we have prospectively studied a series of 31 patients (mean age at injury of 29 years) up to a mean follow up of 10 years after ACL reconstruction. None had chondral defects, 15 had meniscectomies at or before ACL reconstruction. Each patient was assessed at 8 – 13 years following ACL reconstruction with clinical examination, plain xrays (grading OA in 3 compartments as 0,1,2 according to Albach) and a SPECT scan (grading metabolic activity as in 3 compartments: 0 (normal); 1 (increased but not clinically significant); 2 (increased, clini...

The formation of convex microstructures on the surface of polymeric materials under laser irradiation

The formation of convex structures on the surface of colored samples of polymethylmethacrylate (PMMA) when they are irradiated by the second-harmonic radiation of a neodymium laser has been experimentally investigated. The dependences of the height and the diameter of the resulting convex microstructures on the energy density of the laser pulse have been investigated. The formation threshold of structures has been determined for various samples, and the optimum structuring regimes have been found. The possibility of obtaining arrays of convex structures (microlenses) and structures in the form of convex fillets has been demonstrated.

Finite element analysis of flextensional transducer with slotted shell

The study of low frequency, small size transducer was an important aspect for the development of the underwater acoustic transducer. The Class IV flextensional transducer was a typical low frequency, high-power and small size transducer. For decreasing its resonant frequency in the case of small size, a flextensional transducer with slotted shell was analyzed using finite element software ANSYS. A comparison between the flextensioanl transducer with slotted shell and the Class IV flextensional transducer was made. The maximum size of the shell is 200mm. The transmitting voltage response of the transducer reaches to 131dB with resonant frequency 600Hz in water. The transducer could radiate at low frequency with small size of the shell.

Discovering Pedagogical Influences: the Impact of Ethnicity and Gender Representation in Early Childhood Education

For the past decade, we have written and discussed the importance of teaching and the role of the teacher in the classroom.There continues to be reams of research on the significance of teacher preparation and understanding the implications of ethnicity, gender and diversity within the context of teacher knowledge, skills and dispositions.We suggest that, almost paradoxically, the best way to enhance the human dimension of the learning process is to work on explicitly addressing the same issues through meaningful racial discourse and action research with those who plan to teach in America's schools.We propose to explore the personal development and deeper meanings, seek purpose, and understand the power of transcendence.This article focuses on dolls, gender, discovery and metacognitive thought that are major elements in an action research project set in an undergraduate social justice and diversity course.Discovery by undergraduate third year students was obtained through active involvement, observation, interaction and discourse, reflection, intuition and personal experiences.

Hysteresis phenomena in the course of polarization evolution in a sinusoidal electric field in lead magnesium niobate crystals

The processes of polarization evolution in single crystals of the PbMg1/3Nb2/3O3 model ferroelectric relaxor in a sinusoidal electric field are investigated at temperatures near and above the temperature T d 0 of destruction of the induced ferroelectric state upon heating in zero electric field. The polarization switching current loops are measured in the ac electric field applied along the 〈111〉 and 〈110〉 pseudocubic directions. The electroluminescence intensity loops are obtained under the combined action of ac and dc electric fields applied along the 〈100〉 direction. In a certain temperature range above T d 0 and the freezing temperature T f in lead magnesium niobate, there are electric current anomalies, that correspond to the dynamic formation and subsequent destruction of the ferroelectric macroregions throughout each half-cycle of the ac electric field. The measurements of electroluminescence hysteresis loops demonstrate that the observed depolarization delay (related to the ac electric field amplitude) increases with an increase in the dc electric field and decreases as the ac field amplitude increases. The nature of the observed phenomena is discussed.
