Production of Bean (Phaseolus vulgaris L.) under Organo-mineral Fertilization in Humid Forest Agro-Ecological Zone with Bimodal Rainfall Pattern in Cameroon

Bean is an annual legume, consumed by more than 500 million people worldwide. It is a base in their daily diet because of its high protein content (25-30%). In Cameroon, its culture has many problems, including the significant decline in fertility and soil acidity. This study aimed to evaluate the effect of organo-mineral fertilization on the bean production. The experimental design was a complete randomized block with two factors [varieties (NITU and DOR 701) and treatments (T0: Original Research Article Kamtchoum et al.; ARRB, 29(4): 1-11, 2018; Article no.ARRB. 44607 2 control, T1: poultry manure and T2: NPK)] and three replications. The study was carried out at the second cropping season from August to November 2015 in Eloumden in the Mefou and Akono Division, Centre Region (Cameroon). The organo-mineral fertilization of two new varieties of beans was tested. The collar diameter, the number of leaves and the shoot length were evaluated weekly. At harvest, the nodulation and yield were evaluated. The results showed that treatment with poultry manure (T1) induced a very highly significant growth (P ˂ .001) of shoot length, as well as a significant increase in the number of pods (36 ± 5.91), the number of seeds (142 ± 88.07) and the biomass. The chemical fertilizer treatment (T2) induced the best nodulation (25.50 ± 0.87). The treatments did not influence the seed yield. However, the varietal effect was highly significant. DOR 701 had a higher seed yield (5.91 ± 1.03 t ha-1) than the NITU variety (4.19 ± 0.54 t ha-1). Poultry manure (T1) restores the minerals useful for the next crop. It is therefore recommended because of its best yield and its ability to protect the environment.
Undermining Information Hiding (and What to Do about It)

In the absence of hardware-supported segmentation, many state-of-the-art defenses resort to “hiding” sensitive information at a random location in a very large address space. This paper argues that information hiding is a weak isolation model and shows that attackers can find hidden information, such as CPI’s SafeStacks, in seconds—by means of thread spraying. Thread spraying is a novel attack technique which forces the victim program to allocate many hidden areas. As a result, the attacker has a much better chance to locate these areas and compromise the defense. We demonstrate the technique by means of attacks on Firefox, Chrome, and MySQL. In addition, we found that it is hard to remove all sensitive information (such as pointers to the hidden region) from a program and show how residual sensitive information allows attackers to bypass defenses completely. We also show how we can harden information hiding techniques by means of an Authenticating Page Mapper (APM) which builds on a user-level page-fault handler to authenticate arbitrary memory reads/writes in the virtual address space. APM bootstraps protected applications with a minimum-sized safe area. Every time the program accesses this area, APM authenticates the access operation, and, if legitimate, expands the area on demand. We demonstrate that APM hardens information hiding significantly while increasing the overhead, on average, 0.3% on baseline SPEC CPU 2006, 0.0% on SPEC with SafeStack and 1.4% on SPEC with CPI.
Aerobic mineralization of vinyl chloride by a bacterium of the order Actinomycetales

A gram-positive branched bacterium isolated from a trichloroethylene-degrading consortium mineralized vinyl chloride in growing cultures and cell suspensions. Greater than 67% of the [1,2-14C]vinyl chloride was mineralized to carbon dioxide, with approximately 10% of the radioactivity appearing in cell biomass and another 10% appearing in 14C-aqueous-phase products.
Comparisons of mesoscale variability in the Semtner‐Chervin 1/4° model, the Los Alamos Parallel Ocean Program 1/6° model, and TOPEX/POSEIDON data

Measures of mesoscale variability in the Semtner-Chervin 1/4° and the Los Alamos Parallel Ocean Program (POP) 1/6° models were compared with those obtained from TOPEX/POSEIDON (T/P) data. The objectives of these comparisons were two-fold: the first was to validate the models using altimetry as a measure of the variability of the real ocean, and the second was to evaluate the effect of increased model resolution/decreased horizontal friction. Mesoscale root-mean-square (rms) sea surface height (SSH), eddy kinetic energies, and length scales were used to quantify the mesoscale variability. Results showed that the models reproduced the distribution and much of the magnitude of this variability associated with the major current systems; however, in the oceans' interiors the magnitude was underrepresented. The 1/6° and 1/4° models were found to explain about 60% and 50% of the global T/P variability, respectively. Estimates of eddy kinetic energy (and rms velocities) from T/P and the models were compared, demonstrating that the models were less energetic than the T/P fields. Independent comparisons were made with lagrangian drifters in the Pacific basin. Excellent agreement was found between the total POP velocity fields and the drifter data in the tropics, where the T/P geostrophic values were too high due to error amplification by the 1/ƒ factor. In the midlatitudes, the drifter values exceeded those derived from the total model velocities; the T/P results lay between the two. Differences are attributed to the drifter analysis choices and possible residual noise in the altimetry data. The effect of increased resolution/decreased friction was best seen in the length scales where the POP scales agreed more closely with the T/P values than with the 1/4° model The distribution and magnitude of the POP length scales were generally in agreement with the T/P values between 10° and 40°. Near the equator, discrepancies were due to the long equatorial and instability waves, whose long wavelengths were too great to be resolved by the the combination of noise in the altimeter slopes, and the particular definition of length scale chosen.
The Roles of Maternal Depression, Serotonin Reuptake Inhibitor Treatment, and Concomitant Benzodiazepine Use on Infant Neurobehavioral Functioning Over the First Postnatal Month.

OBJECTIVE The purpose of this article was to systematically compare the developmental trajectory of neurobehavior over the first postnatal month for infants with prenatal exposure to pharmacologically untreated maternal depression, selective serotonin reuptake inhibitors or serotonin and norepinephrine reuptake inhibitors (collectively: SSRIs), SSRIs with concomitant benzodiazepines (SSRI plus benzodiazepine), and no maternal depression or drug treatment (no exposure). METHOD Women (N=184) were assessed at two prenatal time points to determine psychiatric diagnoses, symptom severity, and prenatal medication usage. Infants were examined with a structured neurobehavioral assessment (Neonatal Intensive Care Unit Network Neurobehavioral Scale) at multiple time points across the first postnatal month. SSRI exposure was confirmed in a subset of participants with plasma SSRI levels. General linear-mixed models were used to examine group differences in neurobehavioral scores over time with adjustment for demographic variables and depression severity. RESULTS Infants in the SSRI and SSRI plus benzodiazepine groups had lower motor scores and more CNS stress signs across the first postnatal month, as well as lower self-regulation and higher arousal at day 14. Infants in the depression group had low arousal throughout the newborn period. Infants in all three clinical groups had a widening gap in scores from the no-exposure group at day 30 in their response to visual and auditory stimuli while asleep and awake. Infants in the SSRI plus benzodiazepine group had the least favorable scores on the Neonatal Intensive Care Unit Network Neurobehavioral Scale. CONCLUSIONS Neonatal adaptation syndrome was not limited to the first 2 weeks postbirth. The profile of neurobehavioral development was different for SSRI exposure than depression alone. Concomitant benzodiazepine use may exacerbate adverse behavioral effects.
Differentiation of reactive-like astrocytes cultured on nanofibrillar and comparative culture surfaces.

AIM To investigate the directive importance of nanophysical properties on the morphological and protein expression responses of dibutyryladenosine cyclic monophosphate (dBcAMP)-treated cerebral cortical astrocytes in vitro. MATERIALS & METHODS Elasticity and work of adhesion characterizations of culture surfaces were performed using atomic force microscopy and combined with previous surface roughness and polarity results. The morphological and biochemical differentiation of dBcAMP-treated astrocytes cultured on promising nanofibrillar scaffolds and comparative culture surfaces were investigated by immunocytochemistry, colocalization, super resolution microscopy and atomic force microscopy. The dBcAMP-treated astrocyte responses were further compared with untreated astrocyte responses. RESULTS & CONCLUSION Nanofibrillar scaffold properties were shown to reduce immunoreactivity responses while poly-L-lysine-functionalized Aclar® (Ted Pella Inc., CA, USA) properties were shown to induce responses reminiscent of glial scar formation. The comparison study indicated that directive cues may differ in wound-healing versus quiescent situations.
Schubert Varieties and Distances between Subspaces of Different Dimensions

We resolve a basic problem on subspace distances that often arises in applications: How can the usual Grassmann distance between equidimensional subspaces be extended to subspaces of different dimensions? We show that a natural solution is given by the distance of a point to a Schubert variety within the Grassmannian. This distance reduces to the Grassmann distance when the subspaces are equidimensional and does not depend on any embedding into a larger ambient space. Furthermore, it has a concrete expression involving principal angles, and is efficiently computable in numerically stable ways. Our results are largely independent of the Grassmann distance --- if desired, it may be substituted by any other common distances between subspaces. Our approach depends on a concrete algebraic geometric view of the Grassmannian that parallels the differential geometric perspective that is well-established in applied and computational mathematics.
Nutritional education in the primary prevention of osteoporosis in perimenopausal and postmenopausal women

Osteoporosis affects millions of people in the whole world and brings about far-reaching physical and psycho-social consequences for patients and financial ones for the health care system, and therefore it is classified as one of public health problems and treated as a social disease. Women belong to the increased osteoporosis illness risk group due to lower top bone mass reached earlier in life as compared to men and due to hormonal changes occurring in the menopausal period, which affect loss of the bone mineral density (BMD). Limitation of the osteoporosis-related financial and social costs increase requires efficient preventive actions on the level of early, primary, secondary or tertiary prevention. At all the four osteoporosis prevention phases, the crucial role is played by health education and nutrition education, the latter being the key element of the former one. The nutritional education purpose is to acquaint patients with nutrition recommendations that are the basic element of the osteoporosis prevention and to make them change their nutrition habits, which will improve their osseous metabolism. The education should be based on results of the latest scientific researches and focus on recommendations relating to proper supplementing of calcium and vitamin D, simultaneously including all the other nutrition components, necessary to decrease the osteoporosis risk. The primary prevention oriented to a specific group at risk for osteoporosis, including peri- or postmenopausal women, should be provided in cooperation with the different levels’ medical professionals and it should focus on causing positive changes in patients both as regards nutrition habits and physical activities.
The Social Environment’s Relationship With Frailty: Evidence From Existing Studies

Increasingly, policymakers assume that informal networks will provide care for frail older people. While the literature has mainly discussed the role of the family, broader social networks are also considered to be important. However, these social networks can diminish in later life. This systematic review investigates whether the social environment increases the risk of frailty or helps to prevent it. Findings from 15 original studies were classified using five different factors, which denoted five dimensions of the social environment: (a) social networks, (b) social support, (c) social participation, (d) subjective neighborhood experience, and (e) socioeconomic neighborhood characteristics. The discussion highlights that the social environment and frailty are indeed related, and how the neighborhood dimensions and social participation had more consistent results than social support and social networks. Conclusively, recommendations are formulated to contemplate all dimensions of the social environment for further research examining frailty and community care.
Example of a Review Exhibiting Linguistic Characteristics Associated with Deception Distribution of Product Ratings without a with a Confirmed Confirmed Transaction Transaction Difference Expressions Describing Fit and Feel without a with a Confirmed Confirmed Transaction Transaction Difference Indi

The authors document that approximately 5% of product reviews on a large private label retailer's website are submitted by customers with no record of ever purchasing the product they are reviewing. These reviews are significantly more negative than other reviews. They are also less likely to contain expressions describing the fit or feel of the items and more likely to contain linguistic cues associated with deception. More than 12,000 of the firm's best customers have written reviews without confirmed transactions. On average, these customers have each made more than 150 purchases from the firm. This makes it unlikely that the reviews were written by the employees or agents of a competitor and suggests that deceptive reviews may not be limited to the strategic actions of firms. Instead, the phenomenon may be far more prevalent, extending to individual customers who have no financial incentive to influence product ratings. In recent years, many Internet retailers have added to the information available to customers by providing mechanisms for customers to post product reviews. In some cases, these reviews have become the primary purpose of the web-site itself (e.g., Yelp.com, TripAdvisor.com). The increase in product reviews has been matched by an increase in academic interest in word of mouth and the review process Much of this research has focused on why customers write reviews and whether these reviews influence other customers. However, more recently, some of the focus has turned to the study of fraudulent or deceptive reviews (Luca and Zervais 2013; Mayzlin, Dover, and Chevalier 2013). We study product reviews at a prominent private label apparel company. The company's products are only available through the firm's own retail channels; the firm does not allow other retailers to sell its products. The unique features of the data reveal that approximately 5% of the product reviews are written by customers for whom we can find no record of ever purchasing the item. These reviews are significantly more negative on average than the other 95% of reviews, for which there are records that the customer previously purchased the item. They are also significantly less likely to include descriptions of the fit or feel of the garments , which typically can only be evaluated through physical inspection. This is consistent with the interpretation that these reviewers have not purchased the item that they are reviewing. More than 12,000 customers, including some of the firm's highest-volume customers, have …
Macrophage Infiltration Induces Gastric Cancer Invasiveness by Activating the β-Catenin Pathway

Background Despite evidence that activated macrophages act in an inflammatory microenvironment to promote gastric tumorigenesis via β-catenin signaling, the effects of β-catenin signaling on gastric cancer cell metastasis and the relationship of these cells with surrounding tumor associated macrophages have not been directly studied. Methods Immunohistochemical staining was employed to analyze 103 patients. An invasion assay was used to evaluate the relationship between macrophages and gastric cancer cells. β-catenin gain-of-function and loss-of-function approaches were performed. To assess the β-catenin regulation mechanism in gastric cancer cells, Western blotting and reverse-transcription polymerase chain reaction were used. Results Increased density of macrophages was associated with advanced stage and poor survival. Gastric cancer cell lines co-cultured with macrophages conditioned medium showed increased nuclear accumulation of β-catenin and increased invading ability. AKT but not ERK regulated β-catenin translocation. MMP7 and CD44, both β-catenin downstream genes, were involved in macrophage-activated gastric cancer cell invasion. Conclusion(s) Collectively, the clinical data suggest that macrophage infiltration is correlated with increased grade and poor prognosis for gastric cancer patients who underwent radical resection. Macrophages may induce invasiveness by activating the β-catenin pathway.
Lipopolysaccharide Sensitizes Neonatal Hypoxic-Ischemic Brain Injury in a MyD88-Dependent Manner1

Neurological deficits in children, including cerebral palsy, are associated with prior infection during the perinatal period. Experimentally, we have shown that pre-exposure to the Gram-negative component LPS potentiates hypoxic-ischemic (HI) brain injury in newborn animals. LPS effects are mediated by binding to TLR4, which requires recruitment of the MyD88 adaptor protein or Toll/IL-1R domain-containing adapter inducing IFN-β for signal transduction. In this study, we investigated the role of MyD88 in neonatal brain injury. MyD88 knockout (MyD88 KO) and wild-type mice were subjected to left carotid artery ligation and 10% O2 for 50 min on postnatal day 9. LPS or saline were administered i.p. at 14 h before HI. At 5 days after HI in wild-type mice, LPS in combination with HI caused a significant increase in gray and white matter tissue loss compared with the saline-HI group. By contrast, in the MyD88 KO mice there was no potentiation of brain injury with LPS-HI. MyD88 KO mice exhibited reduced NFκB activation and proinflammatory cytokine-chemokine expression in response to LPS. The number of microglia and caspase-3 activation was increased in the brain of MyD88 KO mice after LPS exposure. Collectively, these findings indicate that MyD88 plays an essential role in LPS-sensitized HI neonatal brain injury, which involves both inflammatory and caspase-dependent pathways.
Coral bleaching and recovery in the Thai Andaman Sea

Tropical scleractinian corals are particularly vulnerable to global warming as elevated sea surface temperatures (SSTs) disrupt the delicate balance between the coral host and their algal endosymbionts, leading to symbiont expulsion, mass bleaching and mortality. While satellite sensing of SST has proved a reliable predictor of coral bleaching at the regional scale, there are large deviations in bleaching severity and mortality on the local scale that are poorly understood. Here, we show that internal waves play a major role in explaining local coral bleaching and mortality patterns in the Andaman Sea. Despite a severe region-wide SST anomaly in May 2010, frequent upslope intrusions of cold sub-pycnocline waters due to breaking large-amplitude internal waves (LAIW) mitigated coral bleaching and mortality in shallow waters. In LAIW-sheltered waters, by contrast, bleaching-susceptible species suffered severe bleaching and total mortality. These findings suggest that LAIW benefit coral reefs during thermal stress and provide local refugia for bleaching-susceptible corals. LAIW are ubiquitous in tropical stratified waters and their swash zones may thus be important conservation areas for the maintenance of coral diversity in a warming climate. Taking LAIW into account can significantly improve coral bleaching predictions and provide a valuable tool for coral reef conservation and management.
In vivo models of cardiac diseases: application to drug development and screening

Cardiac disease is the top cause of human mortality in the Western world. Current drug therapy for cardiac disease has been established via experimental studies using a variety of in vivo animal models. The purpose of this review is to discuss the features (advantages and limitations) of the mainly used in vivo models of cardiac disease and provide the reader with an overview of how they can be utilized in the development and screening of cardiac drugs. A search for articles focusing on and including in vivo models for the main areas of cardiac diseases was performed on PubMed. We also searched the reference lists of identified articles for further original articles. Large and small animal models including genetically modified ones have made accomplishments in the process of cardiac drug development with different clinical relevance. However, there is still a clear need for lessening the gap between human and experimental models by improving in vivo models.
International Master’s Degree Students’ Experiences of Support at a Finnish University

This phenomenographic study explores international master’s degree students’ ways of experiencing support in Finnish higher education. The study draws on Schlossberg’s Transition Model and the Culturally Engaging Campus Environments Model as a conceptual framework. The phenomenographic analysis of 17 interviews with international master’s degree students identified four ways of experiencing support as: (a) study system adjustment, (b) learning enhancement, (c) personal growth, and (d) autonomy development. The findings identified participants’ experiencing support in relationships, use of information, communication, services, the flexibility of studies, learning and study environments. The presence of two indicators, Humanizing Educational Environments and Availability of Holistic Support suggested that the campus environment was culturally responsive to academic and personal support of international degree students. The findings contribute to the understanding of support for international degree students in higher education and may be used to develop services to support international degree students’ social, cultural, and career integration into host communities.
