In maize cultivation, the labour-intensive, time-consuming, and costly nature of manual planting necessitates the exploration of mechanized solutions. This study presents a comprehensive economic evaluation of an embedded system-controlled seed cum fertilizer applicator as a potential answer to these challenges. Precise planting methods offer a multi-pronged approach, aiming to reduce cultivation costs, minimize time requirements, and improve worker comfort during planting operations. By meticulously analyzing both ownership and operational expenses, this study empowers farmers with the knowledge necessary to make informed decisions. These decisions could involve adopting the precise seed cum fertilizer applicator technology, optimizing existing machinery, or exploring alternative methods to achieve enhanced farm productivity and financial gains. The embedded system-controlled seed cum fertilizer applicator was directly compared to traditional manual planting methods. This analysis revealed ownership and operating costs of 9.56 Rs/h and 63 Rs/h, respectively. The compelling findings demonstrated a remarkable 96.87% reduction in planting time and a 55.47% cost decrease when utilizing the embedded system compared to manual methods. These results highlight the significant cost-effectiveness and environmental benefits associated with adopting this precise planting system. This research offers valuable insights to farmers, potentially promoting the integration of advanced agricultural technologies that can optimize resource utilization, improve operational efficiency, and contribute to the implementation of sustainable farming practices.

Published: April 2024

Sedimentary structures and petrographic studies of Akpoha area in Afikpo/Abakiliki basin was undertaken in an attempt to understudy and determining constraints in depositional processes in the area . The major outcrops in the area are alternating succession of sandstones and shales striking in a NE-SW direction primarily as a result of folding due to past orogeny in the area. The sandstone outcrops at Akpoha are highly indurated due to age, compaction and tectonism and occur in ridges within the shale unit. The studied shale outcrops were poorly laminated and low in fossil content.Sedimentary structures identified include;Wavy/ripple lamination, Mud cracks, Parallel lamination and Fissility.The results of the petrographic modal analysis from thin section studies show that the sandstone consists predominantly of quartz (55 - 64%); feldspar (22 - 30%) and rock fragment (1 – 9%). The sandstones were immature, poorly to moderately sorted with angular to sub-angular grain shapes which gives clear indication of high energy of sediment deposition and short transport history from provenance.The abundance of well preserved sedimentary structures is an indication of prolong calmness of tectonic/orogenic activities in the area. The fissility observed in shale outcrops and the high induration of the Akpoha sandstones was as a result of compaction from overburden pressure before uplift and exposure.

Published: June 2008

AbstractTo clarify the relation between the drainage pathway of cerebrospinal fluid and the development of idiopathic normal pressure hydrocephalus (iNPH), we examined flow patterns of internal jugular veins in 20 patients with iNPH and 13 control patients using air‐contrast ultrasound venography during the Valsalva maneuver. The iNPH group had a significantly greater frequency of retrograde jugular venous flow (19/20, 95%) than the control group (3/13, 23%) (χ2 test, p < 0.001). Our results suggest that retrograde jugular venous flow may be associated with the development of iNPH; therefore, the analysis of retrograde jugular venous flow could be a useful element in the diagnosis of iNPH.

No correlation between intraocular pressure and intracranial pressure
Authors: Han Ying , McCulley Timothy J. , Horton Jonathan C. 
Published: June 2008

AbstractA recent study has reported an excellent correlation between intraocular pressure (IOP) and intracranial pressure (ICP), suggesting that measurement of IOP may serve as a noninvasive means to determine ICP. To reexamine the relation between IOP and ICP, we reviewed the medical records of all patients who underwent lumbar puncture between 1991 and 2007 in the neuro‐ophthalmology clinic at the University of California San Francisco. Data for IOP and ICP were available for 55 patients. There was no correlation between IOP and ICP (Pearson correlation coefficient, r = 0.07; p = 0.59). IOP measurement is not a useful substitute for ICP measurement. Ann Neurol 2008
A comparative study of reactivity and selectivity of chiral diamines and structurally analogous amino alcohol ligands in enantioselective alkylations with diethylzinc
Authors: Silva Serra M. Elisa , Murtinho Dina , Rocha Gonsalves A. M. d'A. 
Published: June 2008

AbstractA series of chiral δ‐diamines and structurally analogous δ‐amino alcohols derived from natural tartaric acid were synthesized and a comparative study of their activity and selectivity in the enantioselective alkylation of aromatic aldehydes was carried out. Our results show that in general the δ‐diamines were found to be better chiral inducers than the corresponding δ‐amino alcohols. The highest selectivity was observed when benzaldehyde was alkylated in the presence of the benzylic diamine, giving (R)‐1‐phenylpropanol with an ee of 42%. Copyright © 2008 John Wiley & Sons, Ltd.
A bit of prose about poetry
Authors: Akhtar Salman 
Published: June 2008

AbstractThis brief communication delineates 10 outstanding characteristics of poetry. These include poetry's expression of preverbal experience, blending of primary and secondary processes, musical use of words, enhancement of mentalization, reduction of mental pain, cathexis of links and bonds, manifestation of culture, synthesis of neurophysiology, acceptance of the oedipal situation, and its location in the transitional realm. The paper then moves on to deconstruct the form of its message thus far and in the process sheds further light on the “work” of writing poetry. Copyright © 2008 John Wiley & Sons, Ltd.
Boronic Acids in Molecular Self‐Assembly
Authors: Fujita Norifumi , Shinkai Seiji , James Tony D. 
Published: June 2008

AbstractThe reversibility of boronic acid and diol interaction makes it an ideal candidate for the design of self‐assembled molecular structures. Reversibility is required to ensure that the thermodynamically most stable structure is formed. Reversibility also ensures that any errors produced during the assembly process are not permanent.

Enhancement of exciton coupled circular dichroism with sterically encumbered bis‐porphyrin tweezers
Authors: Tanasova Marina , Vasileiou Chrysoula , Olumolade Oluwatoyin O. , Borhan Babak 
Published: June 2008

AbstractPorphyrin tweezers have been successfully used as hosts for the absolute stereochemical determination of a variety of chiral compounds. A set of new porphyrin tweezers with substituted aryl groups on the meso position of the porphyrin rings have been synthesized. The modified tweezers are used as hosts for the stereochemical determination of chiral diamines and carrier‐derivatized α‐chiral carboxylic acids in order to monitor the influence of the various substitutions of the aryl group on the amplitude and sign of the ECCD couplet. t‐Butyl substitution at the meta positions of the porphyrin's meso phenyl substituents leads to enhanced ECCD amplitudes.

Enantiomer separation of triazole fungicides by high‐performance liquid chromatography
Authors: Ying Zhou , Ling Li , Kunde Lin , Xinping Zhu , Weiping Liu 
Published: June 2008

AbstractEnantiomer separation is one of the most important prerequisites for the investigation of environmental enantioselective behaviors for chiral pesticides. In the present study, the enantiomer separation of 7 triazole fungicides, i.e., hexaconazole (1), triadimefon (2), tebuconazole (3), diniconazole (4), flutriafol (5), propiconazole (6), and difenoconazole (7), were evaluated using normal phase high‐performance liquid chromatography. Chrialcel OD column and Chrialcel OJ column were used. The influence of column temperature was studied for the optimization of the resolution as well as the type and percentage of organic modifier in the mobile phase. The retention factors for the enantiomers of all investigated compounds decreased as the temperature increased. The natural logarithms of the selectivity factors (lnα) of hexaconazole (1), tebuconazole (3), flutriafol (5), propiconazole (6) and difenoconazole (7) depended linearly on the inverse of temperature (1/T) while the corresponding values for triadimefon (2) and diniconazole (4) kept unchanged in the studied temperature range 10–35 °C. Van't Hoff plots afforded thermodynamic parameters, such as the apparent change in enthalpy ΔH°, the apparent change in entropy ΔS°and the apparent change in ΔΔH° and ΔΔS°. The thermodynamic parameters (ΔH°, ΔS°, ΔΔH° and ΔΔS°) were calculated in order to provide an understanding of the thermosynamic driving forces for enantioseparation. The established method shows perspective to be used for preparing micro‐scale amount of pure enantiomers of the chiral triazoles studied. Chirality, 2009. © 2008 Wiley‐Liss, Inc.
Theoretical Investigation of the OH.‐Initiated Oxidation of Benzaldehyde in the Troposphere
Authors: Iuga Cristina , Galano Annia , Vivier‐Bunge Annik 
Published: June 2008

AbstractA mechanistic and kinetic study of the OH.‐initiated oxidation of benzaldehyde is carried out using quantum chemical methods and classical transition state theory. We calculate the rate constant for this reaction within the temperature range of 200–350 K at atmospheric pressure. All possible hydrogen abstraction and OH. addition channels are considered and branching ratios are obtained. Tunneling corrections are taken into account for abstraction channels, assuming unsymmetrical Eckart barriers. The aldehydic abstraction is by far the most important reaction channel within the entire range of temperatures studied, especially at room temperature and lower—the temperatures relevant to atmospheric chemistry. The relative importance of all the other possible channels increases slightly with temperature. Branching ratios show that addition at the ring and abstraction of an ortho hydrogen contribute about 1 % each at about 300 K, while the branching ratio for the main reaction decreases from 99 % at 200 K to 93 % at 350 K. The results are compared with available experimental measurements.
Hepatoma‐derived growth factor (HDGF) is dispensable for normal mouse development
Authors: Gallitzendoerfer Rainer , Abouzied Mekky M. , Hartmann Dieter , Dobrowolski Radoslaw , Gieselmann Volkmar , Franken Sebastian 
Published: June 2008

AbstractHepatoma‐derived growth factor (HDGF) is suggested to be involved in organ development and exhibits proliferative, angiogenic, and neurotrophic activity. The in vivo functions are, however, so far unknown. In this study, we generated HDGF‐deficient mice, in which parts of the HDGF gene were replaced by a gene encoding green fluorescent protein (eGFP). HDGF−/− mice are viable with no apparent morphological abnormalities. Cultured HDGF‐deficient dermal fibroblasts show unaltered proliferation rates and cell‐cycle distributions. In contrast to previous studies, our data demonstrate that signal pathways involved in the response to extracellular HDGF do not depend on the presence of intracellular HDGF. Contrary to the reported role of HDGF as a modulator of apoptosis, similar apoptotic rates were found between wild‐type and HDGF‐deficient fibroblasts following tumor necrosis factor α (TNFα) ‐induced apoptosis or cellular stress. The lack of obvious biochemical and morphological phenotypes in HDGF‐deficient mice demonstrates that in vivo HDGF is dispensable for normal development in mice.

Expression and regulation of HTRA1 during chick and early mouse development
Authors: Ferrer‐Vaquer Anna , Maurey Pablo , Werzowa Johannes , Firnberg Nicole , Leibbrandt Andreas , Neubüser Annette 
Published: June 2008

AbstractHTRA1, a member of the high temperature requirement factor A family, is a secreted serine protease that can bind to and inactivate members of the transforming growth factor‐beta (TGFβ) family, modulate insulin‐like growth factor signaling and stimulate long range fibroblast growth factor (FGF) signaling in Xenopus. In vertebrates, so far homologues from mouse, human, and Xenopus have been cloned and studied. Here we report the cloning of the chicken HTRA1 homologue from a screen for FGF8 inducible genes in chick facial mesenchyme. We characterize its expression pattern from gastrulation (Hamburger and Hamilton stage 4) to day 4 of development, and in forming inner organs and limbs. We show that chick HTRA1 has a dynamic expression pattern that differs significantly from the expression of its mouse homolog. We, furthermore, demonstrate that FGF signaling is necessary and sufficient for HTRA1 expression in chick facial and forelimb mesenchyme, but is not required for HTRA1 expression in HH11 embryos.

Treatment of anorexia nervosa in a specialty care continuum
Authors: Treat Teresa A. , McCabe Elizabeth B. , Gaskill Jill A. , Marcus Marsha D. 
Published: June 2008

AbstractObjective:Inpatient hospitalization has been a mainstay of treatment for anorexia nervosa (AN), but decreasing lengths of inpatient stay have prompted the development of alternative care‐continuum models. This study characterizes the 6‐month outcomes of 71 patients with AN who completed an inpatient‐treatment protocol (∼5 weeks), followed by a day‐hospital program (DHP) (∼3 weeks).Method:Data were derived from chart reviews and questionnaire data were collected during routine clinical care.Results:On discharge from DHP, 35.2% of patients showed excellent outcomes, whereas 23.9% exhibited poor outcomes. At 6 months after DHP discharge, 47.9% of the patients were successful in maintaining outpatient treatment status. Patients with successful 6‐month outcomes were admitted to inpatient at a higher weight, had fewer previous hospitalizations, were younger, were rated by inpatient staff as more committed to treatment, endorsed less AN psychopathology during inpatient admission, and showed greater weight gain during DHP. Number of previous hospitalizations and weight gain immediately after inpatient discharge predicted 89.2% of outcome classifications 6 months after DHP discharge.Conclusion:These findings highlight both the potential benefits of this care‐continuum model for patients who previously have not been hospitalized and the pressing need to develop alternative treatment strategies for patients with more chronic AN. © 2008 by Wiley Periodicals, Inc.

Published: June 2008

AbstractOligodendrocytes form an insulating multilamellar structure of compact myelin around axons, which allows efficient and rapid propagation of action potentials. However, little is known about the molecular mechanisms operating at the onset of myelination and during maintenance of the myelin sheath in the adult. Here we use a genetic cell ablation approach combined with Affymetrix GeneChip microarrays to identify a number of oligodendrocyte‐enriched genes that may play a key role in myelination. One of the “oligogenes” we cloned using this approach is Tmem10/Opalin, which encodes for a novel transmembrane glycoprotein. In situ hybridization and RT‐PCR analysis revealed that Tmem10 is selectively expressed by oligodendrocytes and that its expression is induced during their differentiation. Developmental immunofluorescence analysis demonstrated that Tmem10 starts to be expressed in the white matter tracks of the cerebellum and the corpus callosum at the onset of myelination after the appearance of other myelin genes such as MBP. In contrast to the spinal cord and brain, Tmem10 was not detected in myelinating Schwann cells, indicating that it is a CNS‐specific myelin protein. In mature oligodendrocytes, Tmem10 was present at the cell soma and processes, as well as along myelinated internodes, where it was occasionally concentrated at the paranodes. In myelinating spinal cord cultures, Tmem10 was detected in MBP‐positive cellular processes that were aligned with underlying axons before myelination commenced. These results suggest a possible role of Tmem10 in oligodendrocyte differentiation and CNS myelination. © 2008 Wiley‐Liss, Inc.
