Sesame (Sesamum indicum L.) Response to Soil Additives Applied in-Furrow at Planting
Authors: Grichar W. James
Published: February 2024

Aims: Studies were conducted to study the response of sesame to soil additives applied in-furrow.  

Study Design:  Randomized complete block with 4 replications.

Place and Duration of Study: Field experiments were carried out during the 2016 through 2018 growing seasons in south-central Texas near Yoakum (29.27704o N, -97.12453o W).

Methodology: Sesame seed was planted < 2.54 cm deep. Treatments were applied using a CO2-pressurized sprayer in 46.8 L ha-1 of water with one Teejet® orifice disc #45 nozzle per row immediately after seed drop but prior to furrow closure.  Each plot consisted of two rows spaced 97 cm apart and 7.6 m long.  Sprinkler irrigation was applied on a 2- to 3-wk schedule throughout the growing season as needed.  S-metolachlor at 1.4 kg ha-1 was applied preemergence while clethodim at 0.11 kg ha-1 and diuron at 1.12 kg ha-1 were applied postemergence to control annual grasses and broadleaf weeds that were present.  

Results: In 2016, treatments containing 7% N + 10% chelated Fe, gibberellic acid + 3-indolebutyric acid (0.045%) + cytokinin as Kinetin (0.09%), and pop-up fertilizer (9-30-0 + Zn) resulted in the greatest sesame emergence. In 2017, 2% N, bifenthrin + Bacillus amyloliquefaciens strain D747, and humic acids + Bacillus spp. resulted in greater emergence (90-97%) while in 2018, Azospirillum brasilense and 2% N resulted in the greater emergence (90-91%).  In 2016, 2% N produced the greatest yield while in 2018 2% N and the 3-way combination of cytokinin as kinetin (0.090%) + gibberellic acid + indole-3-butyric acid (0.045%) resulted in up to a 117% increase in yield over the untreated. 

Conclusion: The 3-way combination of gibberellic acid + 3-indolebutyric acid (0.045%) + cytokinin as kinetin (0.090%) and 2 % N proved to be the most consistent soil additives and resulted in a yield increases in the two years that the studies were harvested.
Psychosocial Hazards among Field Workers in the Construction Industry Across Demographic Groups in Rivers State, Nigeria
Authors: Ekeke Kelechi D. , Nwaogazie Ify L. , Nnadede K. S.
Published: February 2024

This study explores how psychosocial hazards affect safety outcomes, particularly across demographic characteristics in the construction industry in Rivers State, Nigeria. Questionnaires were distributed to workers in the construction companies in Rivers State to get their responses on psychosocial hazards such as workload, role clarity, social support, and organizational culture. A questionnaire-based survey also collected data on the demographic variables of the workers. Two- hundred and ninty-five respondents had a complete and usable questionnaire. Pearson correlation coefficients and Principal Component Analysis (PCA) were used to understand the relationship between the psychosocial factors with the safety outcome and the relationship with demographic variables. The result revealed that male workers faced higher stress, accidents, and near misses, while females grappled with role ambiguity but reported better social support. The results from correlation analysis revealed that higher workload correlated with increased accidents and near misses. Adequate equipment and suitable environment equate with positive job performance, positive organisational culture leads to low accident rates. Also, clear job roles were linked to improved performance and fewer accidents. Psychosocial hazards have not gained high attention in most industries, but with the improvements in this field of research, safety of workers holistically will be attained.
Mycological and Mycotoxicological Producing Potential of Isolates from Fermented Melon Seeds [Citrullus lanatus (Thumb) Matsun ‘Egusi kirikiri’]
Authors: Opara Christiana Ngozi , Alabere Awengi
Published: February 2024

This study identified and examined fungal presumed producing mycotoxins in fermented melon seed condiment (ogiri). The samples were cultured on Potato Dextrose Agar and Sabouraud Dextrose agar to identify fungi. The detection of mycotoxins in the fermented melon seeds samples was carried out by the use of Coconut Agar Media (CAM), by which the fungal isolates were cultured and plates incubated for 3-7days at 280C. The mycobiota of fermented melon seed revealed of many species belonging to the Aspergillus spp, Penicillium spp, Cladosporium spp, and Rhizopus oryzae. Among all the fungi identified in the study, Aspergillus spp has the highest prevalence rate (44.4%) while Penicillium spp, and Rhizopus oryzae have same value (22.2%).the lowest is Cladosporium spp with (11.1%)  and its presence can be attributed to decaying of the samples. The results obtained show that some of the fungal isolates had the ability to produce mycotoxins. From the mycotoxin screening, only six (6) species (Aspergillus spp, and Penicillium spp) were positive (+), Cladosporium spp, and Rhizopus oryzae were negative (-). Mycotoxin contamination level varied in different market locations in which Swali Market had the highest level of mycotoxin (50%) followed by Opolo Market (33.3%) and Tombia Market (16.7%). Mycotoxigenic producing fungi and mycotoxin levels in fermented melon seed samples are public health concern. Meanwhile, the occurrence of the pathogenic fungi (Aspergillus, Penicillium, and Rhizopus) in fermented melon seed can affect its shelf life and can also cause severe health challenges.
Catalytic Hydroconversion of Lauric Acid Over Poly(N-vinyl-2-pyrrolidone)-Coated Pd Nanoparticles on ZIF-8
Authors: Dahnum Deliana , Ramadhita Holanda , Andreas Andreas , Prasetyo Joni , Bakti Aditia Nur , Dang Huyen Tran
Published: February 2024

A subclass of Metal-Organic Frameworks, Zeolitic Imidazole Frameworks-8 (ZIF-8) is known as an emerging material that has the characteristic of a large surface area, good thermal stability as well as a high porosity. Instead of having extraordinary properties, ZIF-8 consists of Lewis acid and Lewis base site on its Zn metals and 2-methylimidazole which are the important components for the catalyst. In this study, Pd-Poly(N-vinyl-2-pyrrolidone) coated on ZIF-8 (Pd-PVP@ZIF-8) was synthesized by mixed Pd-PVP solution and ZIF-8 precursors at room temperature. The Pd-PVP solution was varied from 10 to 50 ml to differentiate the Pd concentration in ZIF-8. As-synthesized 50 ml of Pd-PVP on ZIF-8 (50Pd-PVP@ZIF-8) showed catalytic activity in the conversion of 98.6% lauric acid to produce 78.2% of 1-dodecanol at optimum condition 320 °C for 6 h. The synergy between Pd-PVP as metal and ZIF-8 as metal support as well as high dispersion of Pd particles could enhance performance in the conversion of lauric acid.

Control of Polymer Composition in Pd‐Catalyzed CO/Olefin Terpolymerization Reactions
Authors: Bastero Amaia , Ruiz Aurora , Claver Carmen , Bella Antonio , Milani Barbara , Moreno‐Lara Belén , Jalón Félix A. , Manzano Blanca R.
Published: May 2005

The CO/tert‐butylstyrene/ethylene terpolymerization catalyzed by Pd‐(N‐N′) complexes was studied. The results evidence that the olefin preferentially inserted in the terpolymer chain is strictly related to the nature of the nitrogen ligand, mainly to its steric constraints, and not to the kind of ligand. Indeed, slight variations in the backbone of the nitrogen ligands coordinated to palladium allow for the synthesis of terpolymers with a controlled composition.
Magnesium‐Lanthanum Mixed Metal Oxide: a Strong Solid Base for the Michael Addition Reaction
Authors: Veldurthy Bhaskar , Clacens Jean Marc , Figueras François
Published: May 2005

Michael additions were achieved quantitatively at room temperature with a broad spectrum of acceptors and donors, using a magnesium‐lanthanum mixed oxide, a strong solid base. The best solvent for the reaction is dimethylformamide, but good yields were also obtained using toluene as solvent. The results obtained with magnesium‐lanthanum are comparable to those reported for super bases. The catalyst can be separated from the reaction mixture and recycled five times without loss of activity with no other treatment.

Highly Efficient Route to Diselenides from the Reactions of Imines and Selenium in the Presence of Carbon Monoxide and Water
Authors: Zhao Xiaodan , Yu Zhengkun , Zeng Fanlong , Chen Jinzhu , Wu Xiaowei , Wu Sizhong , Xiao Wen‐Jing , Zheng Zhaoyan
Published: May 2005

Reactions of selenium with imines (RR1CNR2) of aldehydes and ketones in the presence of carbon monoxide, water and triethylamine lead to reductive selenation, on aerobic work‐up, to afford symmetrical diselenides (RR1CHSe)2 in good to excellent yields. The proposed mechanism suggests that both in situ generated carbonyl selenide (SeCO) and hydrogen selenide (H2Se) are involved in the reaction.

Authors: Gerdin Martin , Moberg Christina
Published: May 2005

Silaboration of 1,3‐cyclohexadiene in the presence of Pt(acac)2, DIBALH, and a phosphoramidite prepared from (S)‐1,1′‐bi‐2‐naphthol and diisopropylamine led to (1R,4S)‐1‐(dimethylphenylsilyl)‐4‐(4,4,5,5‐tetramethyl‐1,3,2‐dioxaborolan‐2‐yl)‐2‐cyclohexene with 70% ee. Chiral catalysts based on Ni gave no or essentially racemic product, whereas complexes containing Pd were inactive.
Study on an Aldol Reaction Catalyzed by Ti(IV)/Calix[n]arene Complexes
Authors: Soriente Annunziata , De Rosa Margherita , Fruilo Marina , Lepore Laura , Gaeta Carmine , Neri Placido
Published: May 2005

Ti(IV)/calixarene complexes, formed in situ or previously prepared with standard procedures, can be conveniently used as efficient catalysts in the aldol reaction of Chan's silyloxydiene with a range of aldehydes bearing either activating or deactivating groups, including aromatic, heteroaromatic and α,β‐unsaturated ones. The structure of both calixarene ligand and aldehyde, as well as the reaction conditions, strongly influence the efficiency of the reaction. NMR experiments in conjunction with the experimental results suggest that the structure of the catalytic species in the Ti(IV)/calixarene system prepared in situ is strongly dependent on the concentration and temperature adopted.
The Multi‐Substrate Screening of Asymmetric Catalysts
Authors: Satyanarayana Tummanapalli , Kagan Henri B.
Published: May 2005

The principle of the one‐pot multi‐substrate screening is presented. This methodology has been successfully applied to various types of catalyzed enantioselective reactions: borane reduction of ketones, addition of organozinc on aldehydes, conjugate addition of diethylzinc on cycloalkenones or nitroalkenes, hydroformylation of olefins, hetero‐Diels–Alder reaction on α‐keto esters, enzymatic hydrolysis of glycerol‐type monoesters as well as hydrogenation of 2‐aryl‐substituted terminal alkenes and enamides. The one‐pot multi‐catalyst screening methodology is also briefly discussed.
A new DAX1 gene mutation associated with congenital adrenal hypoplasia and hypogonadotropic hypogonadism

Published: May 2005

We report on a DAX1 gene investigation in a patient with X‐linked adrenal hypoplasia congenita (AHC) and hypogonadotropic hypogonadism (HH) in order to identify mutations causing this disorder and to confirm the clinical diagnosis. The description of the clinical course of the condition with a detailed documentation of longitudinal data is also reported. A male newborn was referred at 45 days of life because of vomiting, dehydration, and weight loss. The diagnosis was primary adrenal insufficiency. The appropriateness of glucocorticoid therapy during the prepubertal period was difficult to judge because of elevated ACTH levels on one hand and progressive retardation of bone age on the other hand. Basal and GnRH stimulated gonadotropin levels remained low during the entire period of examination and exogenous gonadotropin treatment was begun. This had to be interrupted at age 14.6 years because of the occurrence of a 3rd degree anaplastic ependimoma of the left posterior‐parietal region, without apparent lepto‐meningeal involvement. The molecular analysis of DAX1 gene of the propositus showed deletion of nucleotides AAT in exon 2, resulting in the loss of the Asn430. No alterations were found in the mother and grandmother. This deleted residue lies in one of the helices forming the hydrophobic core of the ligand‐binding domain (LBD); thus this mutation may be the cause of the observed phenotype. Further investigations are needed to verify its causal role in AHC associated with HH. © 2005 Wiley‐Liss, Inc.
Unilateral acheiria and fatal primary pulmonary hypertension in a girl with incontinentia pigmenti
Authors: Hayes Ian M. , Varigos George , Upjohn Edward J. , Orchard David C. , Penny Dan J. , Savarirayan Ravi
Published: May 2005

We describe a newborn girl with incontinentia pigmenti (IP, MIM308300), unilateral acheiria, and fatal primary pulmonary hypertension. Limb deficiency has not been described previously in IP and pulmonary hypertension only on two previous occasions [Triki et al., 1992; Miteva et al., 2001]. A review of the cause of IP shows that these rare manifestations may not be unexpected, given the many roles of the underlying gene product. © 2005 Wiley‐Liss, Inc.
Array comparative genomic hybridization analysis of a familial duplication of chromosome 13q: A recognizable syndrome
Authors: Mathijssen Inge B. , Hoovers Jan M.N. , Mul Adri N.P.M. , Man Hai‐Yen , Ket Jan L. , Hennekam Raoul C.M.
Published: May 2005

We report on a family with six persons in three generations who have mild mental retardation, behavioral problems, seizures, hearing loss, strabismus, dental anomalies, hypermobility, juvenile hallux valgus, and mild dysmorphic features. Classical cytogenetic analysis showed a partial duplication of chromosome 13q, array comparative genomic hybridization showed the duplication to span approximately 21 Mb, ranging from chromosome band 13q21.31 to 13q31.1. The relatively mild presentation of this large duplication may be explained by the relative paucity of genes in the chromosome region involved. Genotype–phenotype correlations in patients with similar partial 13q duplications are inconsistent. Emerging cytogenetic techniques will allow more reliable genotype–phenotype correlations. © 2005 Wiley‐Liss, Inc.
Living with a hereditary disease: Persons with muscular dystrophy and their next of kin
Authors: Boström Katrin , Ahlström Gerd
Published: May 2005

This qualitative study describes conceptions and experiences of the hereditary aspect of muscular dystrophy (MD) from both the patients' and the next of kin's perspective. Different diagnoses of MD are included: dystrophia myotonica, myopathia distalis tarda hereditaria, Becker MD, facioscapulohumeral MD, limb‐girdle MD, Emery–Dreifuss and undetermined proximal MD (Duchenne MD is not included). Interviews were conducted with 46 persons with MD and 36 next of kin. The interviews were subjected to inductive content analysis. Only two in each group did not spontaneously mention anything related to the fact that MD is disease with dominant or recessive inheritance. It was found that heredity has a prominent place in the thoughts and feelings of the family. These thoughts were classified as Becoming aware of MD and its hereditary nature, looking into the pedigree, acquiring an understanding of MD, thoughts about genetic testing, interpreting the risk, whether to have children or not, feelings related to the future, and feelings of responsibility and guilt. Families with MD need medical information and the opportunity for genetic testing as well as support and counseling in coming to terms with living with a hereditary disease, whether or not that includes a decision to take a test. © 2005 Wiley‐Liss, Inc.

The natural history of low‐grade ductal carcinoma in situ of the breast in women treated by biopsy only revealed over 30 years of long‐term follow‐up
Authors: Sanders Melinda E. , Schuyler Peggy A. , Dupont William D. , Page David L.
Published: May 2005

BACKGROUND

Opportunities to study the natural history of ductal carcinoma in situ (DCIS) are rare. A few studies of incompletely excised lesions in the premammographic era now recognized as DCIS have provided critical insights into its proclivity for local recurrence in the original site. At the time the biopsies in the current study were originally examined, small DCIS was not diagnosed and, by default, these women were treated by biopsy only.

METHODS

The authors report the latest results from a follow‐up study, which was published originally in 1982, of 28 women with low‐grade DCIS who were treated by biopsy only. These women were from a large, prospectively identified, completely characterized cohort.

RESULTS

Eleven of 28 women developed invasive breast carcinoma (IBC), all in the same breast and quadrant from which their low‐grade DCIS biopsy was taken. Seven IBCs were diagnosed within 10 years of the DCIS biopsy, 1 was diagnosed within 12 years of the DCIS biopsy, and the remaining 3 IBCs were diagnosed over 23–42 years. Five of these women, including 1 woman who developed IBC 29 years after her DCIS biopsy, developed distant metastasis, which resulted in death 1–7 years after the diagnosis of IBC.

CONCLUSIONS

The natural history of low‐grade DCIS can extend greater than 4 decades, with IBC developing at the same site as the previous DCIS in the majority of women. This natural history differs markedly from that of patients with high‐grade DCIS and from the outcome of patients with any completely delimited DCIS excised to negative margins.

An augmented Lagrange multiplier approach to continuum multislip single crystal thermo–elasto–viscoplasticity
Authors: Celigoj C. C.
Published: May 2005

The material and structural behaviour of single crystals is going to be investigated. On the constitutive level the concept of ‘generalized standard materials (gsm)’ is used to set up the equations for finite deformation multislip single crystal thermo–elasto–viscoplasticity within a continuum slip theory. The only two scalar quantities needed are a thermodynamic potential and a dissipation potential. The resulting evolution equations for the internal (viscoplastic) variables are discretized in time and solved via a backward Euler scheme, using an ‘augmented Lagrange multiplier method’ for satisfying the multiple constraints, thus circumventing the cumbersome and less robust ‘active set strategies’. As a computational reference frame serves the Eulerian setting.

The structural behaviour (non‐linear coupled thermomechanics) is solved in a staggered algorithm: in an isothermal mechanical phase via q1(displacements)/p0(pressure)/j0(jacobian)‐finite elements and in an isogeometric thermal phase via q1(temperatures)‐finite elements, followed by an isogeometric and isothermal update phase of the internal variables.

Numerical results of the simple isothermal shear test of a single face‐centred cubic (fcc) crystal and of the thermomechanical behaviour of a geometrically imperfect strip consisting of initially equally oriented (0/45/30 in Euler angles) fcc‐crystals under tension and plane strain conditions are given.
